The technical field

The present invention relates to portable tools, and more specifically to a wireless field adapter.

Prior art

Portable field instruments for maintenance known. Such tools are extremely useful for process control and industry-related measurements, allowing operators to easily communicate and/or to query a field device at a given process unit. Examples of such processing units include oil, pharmaceutical, chemical process plant and process plant associated with the processing of pulp and other fluid. In such installations, the process control and measurement network can include dozens or even hundreds of different field devices, which periodically require maintenance to ensure that such devices are working properly and/or calibrated. In addition, when the detection of one or more errors in process control and measurement setup using a portable field instrument for maintenance allows the technician to quickly diagnose such errors.

Because at least some the e process plant may include highly volatile or even explosive environment field devices and portable field instruments for maintenance, used with field devices, it is often preferable, or even necessary, to comply with the requirements of internal security. These requirements help to ensure that the electrical device will not create a source of ignition even in conditions of failure. One example of the requirements of internal security set out in the APPROVAL STANDARD INTRINSICALLY SAFE APPARATUS AND ASSOCIATED APPARATUS FOR USE IN CLASS I, II AND III, DIVISION NUMBER 1 HAZARDOUS (CLASSIFIED) LOCATIONS, CLASS NUMBER 3610, published by Factory Mutual Research in October 1998, an Example of a portable field instrument for maintenance, which is subject to the requirements of internal security, includes tool, sold under the trade designation Model 475 Field Communicator, available Fisher-Rosemount Systems, Inc., Eden Prairie, Minnesota.

Taking into account considerations related to the specific environment of the field devices, the transmission signals are traditionally very carefully controlled. Examples of communication protocols industrial processes include the Protocol (Highway Addressable Remote Transducer (HART®and FOUNDATION™ Fieldbus. Both of these protocols are wired protocols, because each field device is formed by a physical wired connection.

Recently, some field devices is yli designed with the possibility of wireless connection. These field devices, therefore, do not require wires for communication or power supply, which simplifies wiring, as well as the interaction with the device. However, portable field instruments for maintenance contacts, which are designed with the possibility of a physical connection to the contact wiring field device, just can't interact with these new wireless field devices.

A detailed description of an example embodiment variants of the invention

Figa and 1B are schematic depictions of a portable field instrument 22 for maintenance, connected to the field devices, in accordance with the prior art. As shown in figa, portable field instrument 22 for maintenance includes a pair of contacts 25, 27, which connect the tive control pins 30, 32, respectively, which are then connected to the contacts 24 of the field device 20. The contacts 24 can be special contacts, allowing you to connect this portable field instrument for maintenance device 20 and to interact with the device 20.

Figv shows an alternative scheme in which the portable field instrument 22 for maintenance connected directly to the circuit 34 process control, which are connected to the field device 23. In any case, a wired connection between a portable field instrument for the maintenance and field device allows a portable field instrument for service to interact with the desired field device 20, 23.

Figure 2 is a schematic depiction of a portable field instrument for maintenance, interacting with the wireless field device, in accordance with a variant embodiment of the present invention. The system 100 includes a portable field instrument 102 for maintenance, wireless image associated with the wireless field device 104 via a wireless field adapter 114 for maintenance. Wireless field device 104 is shown in the form of a pressure transmitter the Oia fluid of the industrial process, having a discharge pipe 106 connected therewith, and a housing 108 for electronics. The housing 108 for electronics is additionally connected to the energy source (in this example, a solar cell 110) and includes a wireless communication unit that establishes wireless communication through the antenna 112. Wireless field device 104 is shown only for illustrative purposes. In fact, the wireless field device 104 may be any industrial device, such as a temperature transmitter fluid process, the level transmitter fluid process, transmitter flow of fluid process, the controller valve or any other device that is applicable for measurements and/or control of industrial processes.

Wireless field device 104 establishes a connection in accordance with the Protocol of the wireless communication process. One example of such a Protocol is the new WirelessHART standard. This standard uses wireless communication on the 2.4 GHz band, but otherwise uses the same command structure, which is used when establishing a connection, Wired HART®. More detailed information regarding the wireless HART®, can be found in the Wireless HART® Specification, published by the HART Communication Foundation. Relevant the e plots Wireless HART® Specification include: HCF_Spec 13, change 7.0; HART Specification 65 - Wireless Physical Layer Specification; HART Specification 75 - TDMA Data Link Layer Specification (TDMA refers to multiple access with time division channels); HART Specification 85 - Network Management Specification; HART Specification 155 - Wireless Command Specification; and HART Specification 290 - Wireless Devices Specification. Although Wireless HART® is one example of the wireless application Protocol process, other standards may be used in accordance with various embodiments of the present invention.

In accordance with a variant embodiment of the present invention portable field instrument 102 for maintenance includes RF module for communication in a relatively short distance, for example, in accordance with known Bluetooth specification, such as Bluetooth Specification 2.1 related power mode 2. However, since the syntax of the command language and the transmission of signals between the Bluetooth and Wireless HART® are incompatible, the ability of a portable field instrument 102 for maintenance to communicate according to the Bluetooth specification does not allow wireless communication with the wireless field device 104. Therefore, variants of the embodiment of the present invention typically use the adapter 114 for bidirectional communication with the wireless field device 104. As will be more podrobnaya below, the adapter 114 includes adaptation through hardware, software, or both providing for communication in accordance with a relatively low power RF communication portable field instrument 102 for maintenance, and communication in accordance with at least one wireless application Protocol process, such as wireless HART®Protocol. Specialists in the art it is clear that because the adapter 114 establishes a wireless link with the portable field instrument 102 for maintenance, and with the wireless field device 104, for each device does not require a physical connection. Therefore, it is assumed that the adapter 114 may simply be a eld module, which is tolerated by the technician during maintenance. Additionally, although the provision of a portable field instrument for the maintenance of the ability to establish direct wireless HART® would obviate the need for the adapter 114, it would not provide the ability to establish communication using the wireless HART® field devices for operating portable field instruments for maintenance, currently used techniques, which shall have connectivity only in accordance with the Bluetooth Protocol. Additionally, since the Bluetooth specification provides a relatively standardized communication, it is assumed that multiple adapters 114 could be used for communication in accordance with a variety of different wireless protocols process that currently exist or may be developed later, through one portable field instrument for maintenance. Thus, to some extent, providing wireless communication adapter of the technological process allows the use of portable field instrument for maintenance, essentially, as a universal wireless Configurator when used with the appropriate adapters 114. Examples of other suitable wireless protocols process, which can be used in accordance with various embodiments of the present invention include protocols supported by the Instrument Society of Automation as the Protocol ISA-SP100.11a, or any other suitable wireless protocols process. Finally, it is also assumed that in addition to the specifications Bluetooth adapter 114 may include any suitable additional or alternative protocols RF link, for example, and is known protocols Wi-Fi, in accordance with the family of IEEE 802.11 protocols for WLAN, and/or known signaling protocols with radio frequency identification.

Suitable examples of such protocols include the well-known specification 124 Bluetooth connection in accordance with IEEE 802.11 126 or the communication protocols for the transmission of signals used in known technology 128 radio frequency identification (RFID). Each module 120 and 122 is connected to the controller 130, which preferably is a microprocessor. By suitable adaptations using hardware, software about the level or both, the controller 130 configure with establishing a bidirectional communication using both modules 120 and 122. Thus, the signals received by the module 122 can be processed, and information based on such signals may be transferred through the module 120. On the contrary, the signals received by the module 120 wireless communication process, can be processed, and based on these information can be transmitted via the module 122 of the wireless application Protocol. Additionally, in variants of the embodiment of the present invention, which uses multiple low-power RF modules 122 communication Protocol, definitely it is assumed that the controller 130 may be configured to convert or another adaptation of the signals received from one adapter 122, in accordance with the first Protocol information via the second module 122 in accordance with the second Protocol. For example, in variants of the embodiment in which the adapter 114 includes a Protocol module of a wireless communication process to establish communication in accordance with a Bluetooth module for communication in accordance with Wi-Fi, the controller 130 may be adapted to transform or another transition between Bluetooth and Wi-Fi.

The adapter 114 includes a module 132 power, coupled with all the other components of the adapter 114, as indicated by the arrow 134, labeled “all”. Module 132 power supply is preferably a battery, but can be any suitable power source that can store, generate or maintain a suitable electric power for operation of the adapter 114.

Historically, obtaining data from the field device meant physical connection of the device with a suitable field tool for maintenance or, in the worst case, destruction of field devices of the process to verify the required details in the workplace. Creating a physical connection to the contacts of the field device to obtain access to the necessary data can be complex depending on the location and installation of the field device or simply impossible due to the inability of the opening device for the ode for security reasons. In accordance with a variant embodiment of the present invention wireless field adapter for maintenance allows you to transmit signals from the wireless field device to a portable field instrument for maintenance, which preferably is internally secure. Additionally, signals may be transmitted from a portable field instrument for maintenance on the wireless field device or the wireless network to determine and/or record data before and after calibration for the wireless field device. The signals converted by the wireless communication adapter process can be queries with a portable field instrument for maintenance of the wireless field device or data from the wireless field device.

In accordance with one embodiment of the adapter 114 may be physically connected to the module 138 wired communication process and contacts 140, 142 with conductive contacts of the portable field instrument for maintenance. Therefore, in this variant embodiment, the adapter 114 receives signals from a portable field instrument for maintenance through the contacts 140, 142 and generates the wireless HART® wirelessly with denim field device for determining and/or write data to/after calibration for the wireless field device. Therefore, in this variant embodiment, the adapter 114 converts or otherwise adapts wireless signals HART® - enabled wireless HART® field device or network signals HART®, which can be processed portable field instrument for maintenance.

In another variant embodiment in which the portable field instrument for service may be able to establish communications in accordance with the Protocol of the relatively low power, radio frequency communications, such as Bluetooth, adapter 114 need not be physically connected to a portable field instrument for maintenance or wireless field device. In this variant embodiment, the adapter 114 converts Bluetooth signals from a portable field instrument for maintenance in wireless signals of the technological process, for example in accordance with the wireless HART®, which are then passed on to a supporting wireless communication of the field device, or the network connection process. The adapter 114 converts the wireless signals of the technological process with supporting wireless communication of the field device or network in the Bluetooth signals that can be processed and/or stored portable field instrument is entom for maintenance. Preferably, and portable field instrument for maintenance, and the adapter 114 design with regard to submission requirements of internal security, such as the aforementioned requirements.

The method 200 begins at block 202 where the wireless field adapter for maintenance combined with a portable field instrument for maintenance. The connection is carried out in block 202 may be performed or physically 204, or by pairing Bluetooth 206. Each of these technologies described above. Method 202 proceeds to block 208 where the technician interacts with the portable field device maintenance for generating a request for data before and after calibration. Next, at block 210 portable field device maintenance communicates with a wireless adapter for maintenance for communication with the wireless field device to determine and/or record data before and after calibration. Extras can be stored in any suitable complement is supplemented flax information, related to the measurement, the state of the wireless field device, the device configuration, or any other suitable information. Additional information may include a time stamp and/or date, and an indication of the location indicated by the GPS sensor of the wireless field device.

As shown in figure 4, these data can be saved or portable field instrument for maintenance, as shown in block 214, or through a database device or software package for resource management, as shown in block 216.

Another common responsibility for maintenance, which greatly facilitates wireless field adapter for maintenance according to the variant embodiment of the present invention is a test checked paths and segments of the communication process. The normal responsibility of the service technician is “testing testing” of the control loop or segment to verify that the field device installed in it, correctly connected, that the transaction is complete and accurate, that energy is available and that the signal device is properly installed and configured in accordance with the tre is Rovaniemi. This validation testing is often performed using portable field instrument for maintenance, for example, a portable device or laptop loaded with the required software, which can cause the desired response from various field devices for testing other field devices, such as meters, recorders or signalling device in circuit communication process.

Historically conducting verification testing using a portable field instrument for maintenance demanded access to the field device or circuit connection process using the physical connection from the control room or at the factory. Conducting such a test enables the technician to check the required response (e.g., indication of a measuring instrument or audible alarm) from other devices in the circuit. However, creating a physical connection can be a complex or time-consuming depending on the location of the access points in the circuit.

In accordance with a variant embodiment of the present invention, the signals may be transmitted from a portable field instrument for maintenance, which preferably is intrinsically safe field device or firewall interface is in circuit communication process to “test validation” of the control loop or segment to verify, for example, that the device is properly installed, the transaction is complete and accurate, the energy available and the signal device is properly established and configured in accordance with the requirements.

In one variant embodiment, the adapter 114 is physically connected to the conductive contacts of the portable field instrument for maintenance. For example, the contacts 140, 142 can be physically connected to contacts of a portable field instrument for maintenance. The adapter 114, therefore, in essence, converts the signals wired HART® portable field instrument for maintenance, using module 138 wired communication process signals that can be transmitted to the wireless field device through the module 120 wireless application Protocol process. The adapter 114 may also convert or otherwise adapt the wireless signals of the technological process of supporting wireless communication of the field device or firewall wired interface signals process that can be handled by a portable field instrument for maintenance.

In this variant embodiment, the adapter 114 receives low-power radio frequency signals, such as Bluetooth signals with a portable field instrument for maintenance, and use of appropriate configuration and/or software commands, the controller 130 may convert such signals into suitable signals for wireless communication process. For example, the Bluetooth signal can be converted to wireless signals HART®. These wireless signals of the technological process can be transferred to a supporting wireless communication of the field device or gateway. The adapter 114 is also configured to convert the wireless signals of the technological process in the Bluetooth signals that can be processed portable field instrument for maintenance.

In another variant embodiment, the adapter 114 may be physically connected to or removed from the Bluetooth-enabled computer that is running the required software to perform the testing circuit and/or the test segment. In the data the m variant embodiment of the adapter 114 converts Bluetooth signals from your computer to the wireless signals of the technological process, for example, wireless signals HART®, which are then passed on supporting wireless field device or gateway. The adapter 114 also operates in the reverse direction, i.e. the signals of the wireless communication process with supporting wireless communication of the field device or firewall interface is converted by the adapter 114 in the Bluetooth signals that can be processed by the computer.

In yet another variant embodiment of the adapter 114 may be physically connected to the USB port on your computer.
