The buttons 122 may include a numeric keypad, an alphanumeric keypad or the appropriate number of special functions and/or navigation buttons or any combination of them.

Fig. 3 shows a block diagram of a portable field instrument for maintenance in accordance with a variant implementation of the present invention. Preferably, the tool 52 correspond to at least one of the specifications relating to internal security, such as that listed above, to help ensure safety in potentially explosive environments. Handheld field tool 52 for maintenance includes, at least, the module 121 wireless technological process. Appropriate examples module 121 wireless technological process includes a module that generates and/or receives the correct signals from�testii with a known wireless communication Protocol, this is known as WirelessHART (IEC 62591). Another wireless Protocol technological process outlined in ISAlOO.l la. Although in Fig. 3 shows one module 121 wireless technological process, especially considered that any suitable number of wireless technological process can be used to maintain a connection in accordance with different wireless communication protocols technological process that now exist or will be developed later. Although embodiments of the present invention, in General, are described in relation to internally secure the portable field instrument for maintenance, which includes at least one communication module of technological process, a certain variant of the implementation can be implemented in practice without maintaining connection of the technological process, using only location information GPS and portable tools.

Handheld field tool 52 for maintenance also includes at least one additional module 123 of the wireless communication Protocol. Module 123 of the wireless communication Protocol can support communication in accordance with one or more options shown by dotted lines in Fig. 3. More specifically, the module 123 Protocol wireless�Oh connection can communicate in accordance with the specification 124 Bluetooth (such as Bluetooth 2.1 specification, related to power mode 2); specification 126 Wi-Fi (such as IEEE 802.1 l.a/b/g/n); known specification 128 radio frequency identification (RFID); technology 130 cellular (such as GSM/CDMA) and/or satellite communication 132. These communication technologies and methodologies allow portable field instrument 52 for maintenance liaise directly with your wireless gateway or other suitable device, either through a direct wireless connection, or using the Internet. Although one in Fig. 3 shows one unit 123 of the wireless communication Protocol, you can use any suitable amount. Each module 121 of the wireless Protocol of the technological process and module 123 of the wireless communication Protocol connected to the controller 130, which is also connected to module 138 wired communication process. The controller 130 is preferably a microprocessor that executes a sequence of instructions that are stored in it or in a memory connected to the controller 130, to perform tasks for a portable field instrument for maintenance. The module 138 wired communication technological process allows to provide the physical connection of a portable field instrument 52 for maintenance via a wired connection to�bars 142, 144 in a field device. Examples of suitable wired communication technological process includes the communication Protocol with the remote sensor highway addressable (HART®) Protocol Fieldbus FOUNDATION Fieldbus, Profibus and others.

Handheld field tool 52 for maintenance includes a module 156 user interface to generate a user interface using the display keys 120 and 122. The module 156 may include circuit 158 display driver and/or the memory to communicate with the display 120. The module 156 also includes circuitry 160 of the input, which is configured with the possibility of interaction with the buttons 122 for receiving user input. In addition, in embodiments where the display 120 includes a touch screen, the module 160 may include a scheme for generating user input data in the controller 130 on the basis of touch and/or gesture taken by a touchscreen.

Handheld field tool 52 for maintenance may involve a number of additional elements that facilitate additional functionality. More specifically, the tool 52 may include a detection module location, such as a GPS module 150. The GPS module 150 can be configured with the ability to complement�form of further use of the regional system of the radiodetermination satellite location by the respondents on the frequency of the request (WAAS) to provide increased accuracy and/or optionally can be configured with the ability work using differential GPS technology. The module 150 is connected to the controller 130 to provide the controller 130 with indication of the geographical location of the tool 52. Although the detection module 150 location is preferably an internal tool element 52, it can be an external element and communication associated with use of a suitable Protocol wireless or wired connection, such as Bluetooth 124, 128 and RFID etc. moreover, although the detection module 150 location, usually described as the GPS module 150, you can use other technology to triangulate location of the portable field instrument for maintenance on the basis of the relative strength of the wireless communication with the wireless transceiver having a known fixed location. Examples of such wireless technologies triangulation include triangulation location of the portable field instrument 52 for maintenance on the basis of three or more points WiFi connection with a fixed position or access points. Moreover, as described above, embodiments of the present invention may include the ability to use one or more modules of the wireless Protocol and technologiesprocessor, such as module 121. Such technologies triangulation can also be used in the case that it is possible to achieve a suitable number of wireless communications with the wireless field devices with a fixed location. Finally, while various methods are provided for obtaining a location of a portable field instrument 52 for maintenance, as described above, they can also be used in conjunction with each other to provide additional accuracy and/or redundancy. In addition, the tool 52 also preferably contains a module 152 compass coupled to the controller 130 so that the tool 52 could show the compass direction in which it points. Finally, the tool 52 may also include a module 154 of the slope, coupled with the controller 130 to provide indication to the controller 130 relative to the angle of the instrument 52 relative to gravity. However, also consider further the measurement axis.

The module 150 location detection module 152 of the compass and the module 154 slope are particularly useful where a portable field instrument for maintenance assists the technician or engineer to find the physical location of wireless field devices in the field. Refinery is often �very big technological installation with multiple field devices, located in different locations, some of which may be quite invisible. When the technique or the engineer must physically identify the location of the field device to perform the engineering works, installation and/or maintenance tasks, technique or engineer will need to pre-execute one of the following tasks. The technician or engineer will be forced to find a field device based on the memory or on the basis of written or oral instructions from another technician or engineer. Alternatively, a technician or an engineer will look for the field device to the technical drawings, which often do not contain detailed information regarding the physical location of the device. Then, based on the often limited information technician or engineer will attempt to physically determine the location of devices in a plant or process unit.

Variant implementation of the present invention typically uses a geographical information regarding a field device with a fixed location, and information is loaded into or otherwise created inside a portable field instrument for maintenance for portable field instrument for maintenance helped uses�the user to navigate to the physical location of the field device. Moreover, in some embodiments, this location information can be transferred from one portable field device for maintenance to the other so that the portable field instrument for maintenance of other equipment can be supplemented with location information from a portable field instrument for the maintenance of the first technique is to ensure that both techniques were able to quickly and easily find the best route to the physical location of the field device. Preferably, this transmission of information between portable field instruments maintenance is performed wirelessly, but you can use any suitable technology to transmit information between portable field instruments for maintenance.

As shown in Fig. 3, a portable field instrument 52 for maintenance preferably includes a chamber 157. The chamber 157 is preferably located inside a portable field instrument 52 for maintenance and configured with the ability to capture still and/or video images. In addition, the chamber 157 can also be done with audio input so that you can provide video z�ing with sound in real time.

Embodiments of the present invention typically use a portable field instrument for maintenance with the ability to determine its own location in order to facilitate maintenance in the field based on your location. Preferably, a portable field instrument 52 for maintenance uses GPS and/or cellular triangulation or triangulation WirelessHART (wireless HART) to help the technician to find the optimal route to the location of the field device or processing facility within the allowable radius. Using wireless triangulation of the signal (in addition to simple use of GPS) is important because the industrial process equipment typically generates noise of traditional alarms/GPS receivers. Thus, the module location, which is configured with the possibility of using triangulation in a place or in combination with GPS, is predominant in the process unit. Moreover, triangulation WirelessHART is especially preferred due to the presence of numerous control points (such as the number of wireless field devices with a fixed location) in close proximity to the object.

For about�to lagcity maintenance at the place on the basis of location, each field device usually has its own physical location, or has some other way when it is put into operation or interacts with technology. The second way in which a technician for maintenance in the field can set the location of the device, serves to make the technician for maintenance in the field can run or otherwise execute a software application stored in memory of the controller 130 and reproduces a map on the display 120. The map will show the location of the portable field instrument for maintenance, which defined the module 150 of the positioning. Then the technician may move to a position that is next to the field device, if possible, without loss of signal accuracy location detection (GPS/cellular/WirelessHART/WiFi) and then drag, or otherwise interact with, an icon depicting a field device on a map. If the input field device does not already exist in the local database of a portable field instrument for maintenance, you enter. Then the technician moves the icon field devices on the map in any direction and at any distance relative to the current position of perinon�th field tool for maintenance until while the technician is not satisfied that the specified position on the minimap is a valid representation of physical reality. Alternatively, the technician can simply move the portable field instrument for the maintenance in position of the field device. Next, the technician selects the icon and sets the location in a portable field instrument for maintenance. This allows you to save the location information that represents a current location of the portable field instrument for maintenance, which was modified by the displacement vector based icons equipment, if applicable.

Map, which is reproduced on the display 120, may be any suitable graphical representation of the location of the portable field instrument for maintenance relative to the field device. Preferably, the map is two-dimensional, but may be three-dimensional. In addition, the technician can also determine the height of the field device by entering data. Coordinate envisaged for height, can be either positive (height above ground) or negative (depth below ground). The parameter "height" usually makes pictograms card to appear slightly different�governmental (such as transparent), when a portable field instrument for maintenance is in the same exact location as the field device in order to indicate to the user that the field device is not located at ground level. Preferably, the transparency varies depending on the distance from the ground level. For example, the further field device is located on the ground level, the more transparent becomes the associated icon field devices. Additionally or alternatively, the height setting directly or height may be displayed near or on the icon of the field device. Moreover, any other suitable visual indication relating to the field device can be envisaged in order to show the height parameter. For example, you can change the color of the pictogram field device from the first color, showing the depth below ground, to a second color indicating the value of the height above the ground. For technological objects that do not support the relationship, such as a large tank, a pictogram or other suitable for its performance, preferably shows the lack of communication through the properties icon. For example, a red icon may show the object process unit that does not support the connection.

When the technician nanos�t the location of the field device on a map, portable field instrument for service may communicate with the field device through the module 138 wired communication process or module 121 wireless technological process, depending on the situation, in order to assign location coordinates (such as latitude, longitude, and altitude) of this field device. Alternatively, a portable field instrument for service may interact with the control system of objects to update, or otherwise preserve, the location information field of the object. In addition, field devices that do not use the digital connection (such as a traditional device that uses the alarm 4-20 mA), can also determine the location using a portable field instrument for maintenance, and the location of such devices can be downloaded to the control system objects. In embodiments where the handheld field tool for maintenance is not freely available to the control system of objects, a portable field instrument for maintenance can directly just to keep and maintain a database that tracks objects that stores the location information field, and then later synchronize with the app related to the management of objects on the basis of a personal computer.

Although any or all of the field devices can be put on the map, or in other cases have their own specific and stored physical location, other technological devices and/or devices can also similarly be applied to the card. Any device or object in the processing unit can, in essence, assign an icon, and thus, the location. For example, most equipment, such as a reservoir, can be fixed in the form of a reference point on the map. In this scenario you want the database objects within the application associated with the management of objects and/or portable field instrument for maintenance, since the reservoir is not necessary will liaise in accordance with the industrial communication Protocol for the process.

To further facilitate maintenance in the field on the basis of location, separate connections field devices to the rest of the bus/network connection process (e.g., block Spur) can be captured and saved in the field device or the database objects in the form of coordinates of the point of connection to the installation. These coordinates can be included in the CE�I standard GPS coordinates to determine the location of the connection concentrator (longitude, latitude, altitude), and possibly the fourth parameter (the number of terminal blocks or identification), which uses techniques in field conditions to determine which end-to-end connection used for connections, apply power to the field device.

Fig. 4 shows a block diagram of the sequence of operations of a method of determining the location of a field device according to the embodiment of the invention the present invention. Method 200 begins at step 202, where choosing a field device. The choice of field device may be performed by the user or the technician initiating the search label 204 of the object field device. Additionally, if the user uses or has access to the application, such as a host DCS 206, the system 208 manipulate objects or the application 210 for controlling a portable tool, the user or technician can cause the context-sensitive menu, for example, by clicking with the right mouse button on the field unit to select the field device.

After selecting a particular field device, in step 212 receives location information for a selected field device. As stated above, this location information can be stored locally in a portable field instrument for maintenance or stored in a database in the system control�Oia objects. In addition, the location information can even include the manual recording and notes. The location information obtained in step 212, serves in an independent manner in a portable field device for maintenance, and in step 214 to produce the map. Preferably, the map is initially centered on a field device, shown with the location information. Then use the current location of the portable field instrument for maintenance on the playback icon or image location of the portable field instrument for maintenance relative to the selected field device. This is only the preferred option implementation, since it is also assumed that the portable field instrument for maintenance can represent a point in the center of the map. Preferably, the cards I make reference to the North or reference, which is based on the current heading of the portable field instrument for maintenance specified module 152 of the compass. Preferably, the map scale is automatically selected so that the initial playing cards placed portable field instrument for maintenance near the edge of the map with the selected polivy� device in the center of the map or Vice versa. Additionally, the background image is preferably used to provide scale. For example, you can use a kind of technological installation from the satellite. However, any suitable graphical representation of the process plant, developed or derived from drawings or blue prints of the drawings computer-aided design (CAD), can be used in addition to or instead of satellite. Finally, aerial view, photographed from a plane, can also be used for the background image. Preferably, the user interface provides a technique that can handle the card by zoom in for more detailed view or zoom out for a more detailed display of landmarks. Alternatively, the background image can be a source image object to show the technique, which performs the search, the approximate appearance of the field device.

After playing cards, or display it in any other way, a technician will be sent to the region field to determine the location of the selected field device or the object of the process. As a portable field instrument for maintenance detects a change in the location of the equipment, handheld field in�trument for maintenance, re-tests, if a technician within the selected proximity field device 216. If a technician has not reached the selected location to the field device, the map is updated continuously, as shown in step 218, and the cycle continues until the technician reaches the selected location of the field device. After reaching the selected location of the field device, in step 220 to initiate the location determination the immediate vicinity.

In General, using the simple options location-GPS/cellphone/WirelessHART is difficult to determine the location of the field device among a group of field devices that are limited to a small geographic area. In order to provide additional assistance technique after reaching the selected location, provided at least two options location-close proximity. The first option location-close proximity based RFID tags. RFID use communication in the near zone for the exchange of information between the label and reader. RFID-tags are quite useful, but generally require close proximity to the RFID reader. Active RFID tags have a large range, in addition, require a battery and are quite expensive. As shown in Fig. 3, the module 128 RFID can be used to mutually�of deystviya with RFID tags in the selected field device to achieve location-close proximity. The second option for determining the location of close proximity is a relative coordinate 224 location. Relative location coordinates comprise a pair of numbers (1, 1) to (255, 255), description of the point from the point of view of a person standing to the South links, and facing North in the direction of the link. For example, the wellhead (facing North) can be a starting point. And again, the map is preferably created where visible objects fully visible (i.e. not transparent). Devices, hidden from the sight of the wellhead or other equipment, are preferably transparent. Coordinate (1, 1) will represent the top left corner of the viewing area of technology, and the coordinate (255, 255) will represent the bottom right corner of the viewing area. If the camera is mounted on a portable field instrument for maintenance, we can also get the image to display on the viewing area. Once the technician has determined the location of the field device, using 220 of determining the location in the immediate vicinity, the location is preferably checked. One way in which to test the device with a specific location, is the presence of or reference to a physical tag field of the mouth of�STS. In some cases, this may be impossible if the label has been damaged or subjected to some degree of corrosion. Preferably, the field device is set with a jumper or a button or other suitable schema to which you can get local access with equipment maintenance in the field to produce a shrill signal 226 to broadcast their own communication circuit of the technological process field device or segment that uses a native communication Protocol of the technological process field devices. A portable tool for maintenance, which uses techniques, then listens for the loop/segment connection, the technological process for piping signal or message to confirm that the technician has performed the correct device that produced a shrill sound before servicing the device.

Fig. 5 depicts a block diagram of the sequence of operations of way maintenance in the field, assisted in determining the location, according to an embodiment of the present invention. Method 300 begins at step 302 where a portable field instrument for maintenance is connected with the possibility of establishing a connection with a co�round or segment of the communication process. Next, in step 304, a portable field instrument for maintenance establishes a connection with the contour of the connection or segment of a technological process for the identification of all field devices on the contour or segment of the communication process. In step 306, a portable field instrument for maintenance requests each field device in order to obtain the physical location or coordinates, and the number of terminal blocks that connect the field device with loop or segment of the communication process. Preferably, the location or coordinates of the terminal block also served in a portable field instrument for maintenance with field devices. In step 308, a portable field instrument maintenance technique provides an indication relative to the terminal block. Thus, the technician can ensure that the correct field device is disconnected from the terminal block in the case where it is contained without the need for reverse tracing wires.

Fig. 6 shows a block diagram of the sequence of operations of way maintenance in the field, assisted in determining the location, according to an embodiment of the infusion�his invention. Method 320 begins at step 322, where the handheld field tool for maintenance is connected with the possibility of maintaining communication with the field device. Next, in step 324, a portable field instrument for service passes the request to the field device to obtain the location of its terminal block. In step 326, a portable field instrument for maintenance plays a card or other suitable display technique via the display 120 in order to send a technician to the location of the terminal block of the field device.

Fig. 7 shows a flow chart of a method for performing maintenance in the field, assisted in determining the location, according to an embodiment of the present invention. Method 340 begins at step 342, where the technician selects a specific object, process or piece of equipment using a portable field instrument for maintenance. Next, in step 344, a portable field instrument for maintenance issues a request to the local database or remote system management facilities to identify all of the field devices and/or features of the process plant associated with the selected technological�they object or piece of equipment. In step 346, the portable field instrument for maintenance displays all associated devices and objects on the map for technology.
