The technical field to which the invention relates
The present invention, in General, refers to the device with AC power, which includes a control device such as a microcontroller or the like In a specific embodiment, the present invention relates to a driver for controlling the light source such as led or a gas discharge lamp; hereinafter the present invention is specifically described here for the case of this driver, but it should be noted that the invention can be applied in many other situations.
Background of the invention
Figure 1 shows a block diagram of the electronic driver 1 to control the light source 2 with a power driver from the network. In particular, the driver 1 has input terminals 3, 4 for connection to the network and output terminals 8, 9 for connecting the lamp 2. As is known to experts in the field of technology there are several options for implementing such electronic driver. Because these drivers are well known, and the precise embodiment of the driver has nothing to do with the implementation of the present invention, a detailed description of embodiment of the driver are omitted here. However, it is essential that the driver 1 includes a device 10 controls driving operation of the driver, and that this controller will is replaced with the possibility of programming (i.e. you can change the software and/or parameters stored in the storage device). The control device can be implemented, for example, in the form of a Central processor, microprocessor, microcontroller, etc., and hereinafter referred to as the controller.
For the proper functioning of the driver 1, the controller 10 must be setup and configured, which is usually done on the test bench manufacturer. The process configuration can produce as staff, and configures the device, which itself may be implemented as a software application running on a computer (PC, laptop). In any case, the process requires data to the controller and from the controller.
Up until the controller 10 is not built into the driver, to communicate with the controller is relatively easy. However, once the controller 10 is built to communicate with the controller becomes much more difficult. To provide access to the controller from the outside it is necessary to provide physical contact with the controller using special connectors and/or to provide the driver 1 separate connector. However, these solutions are relatively expensive.
The present invention is the provision of solving the above problems.
Given the th, the need for communication with the controller, basically, there are only at the production stage driver, a particular object of the present invention is to provide a simple and cheap way of communicating with the controller, make the minimum possible changes to the driver.
In one aspect, the present invention provides a controlled power source capable of creating an alternating voltage the frequency of which can be controlled. It should be noted that in WO-98/21803 describes a system in which the frequency of the current supply network is managed by the order management systems of energy consumption on a national scale. This system, obviously, is not suitable for configuration of one individual electronic driver. There are only minor changes in the frequency and duration of the signals is sufficiently large, of the order of several seconds per bit. Additionally, it is noted that all the documents WO 2009/040718 A2, US 2005/231128 A1 and US 2003/030386 A1 describe the controlled power source capable of creating an alternating voltage the frequency of which can be modulated to transmit data. The modulated AC voltage is used to power the source of electromagnetic radiation such as light, so that the data contained in the modulation, is transmitted through electr the magnetic radiation, generated by the source.
In the second aspect, the present invention provides testing equipment, equipped with such a controllable power source; a driver in such equipment it is possible to provide a controlled power source from the network, that is, a source of alternating voltage whose frequency is modulated. For the specialist in this area should be clear that the frequency modulation enables transfer of data.
In the third aspect, the present invention provides a driver that is able to perform the demodulation of frequency-modulated voltage power supply.
In the fourth aspect, the present invention provides a method of downloading information from a voltage source in the device receiving the energy from this voltage source.
Additionally, it is preferred that the controller can communicate in the opposite direction to the device programming without the need for special lines. Therefore, in the fifth aspect, the present invention provides an electronic driver contains a controller, configured to modulate the current consumed from the voltage source.
In the sixth aspect, the present invention provides test equipment, containing a current sensor for detecting Tulyaganova current.
In the seventh aspect, the present invention provides a method of loading information into the voltage source from the device, powered from this voltage source.
In the eighth aspect, the present invention provides a means for two-way communication over the power lines.
Additional preferred development are mentioned in the dependent claims.

Detailed description of the invention
Figure 2 schematically illustrates the device 100 programming for electronic driver that contains the device 20 p is ogromnogo control and source 30 voltage, suitable for providing voltage Vs power supply driver electronic lamps and considered as a replacement of the normal mains supply. For example, the voltage source configured to generate an alternating voltage with amplitude of about 330 at its output terminals 38, 39 connected to the output terminals 108 of the device 100 programming. In the input stage of the driver lamp (or other device that receives this voltage) input voltage is first rectified, for example, using a diode bridge, as it should be clear to the person skilled in the technical field, proper operation of the lamp driver (or other device) to a greater or lesser extent, depends on the frequency of the input AC voltage. For conventional power sources, in particular, for the normal mains power supply, the power frequency is almost constant (i.e., 50 Hz in Europe). A separate aspect of the present invention is that the frequency of the supply voltage is modulated to transmit data to the driver of the lamp (or other device). The source 30 voltage has an input 31 of the control, and the device 20 program management has an output 21 of the control connected to the data input 31 management; source 30 voltage is arranged to establish its in the output frequency in accordance with a control signal, taken at the control input 31.
Frequency modulation can be performed in many ways, as should be known to specialists in this field of technology, and in principle all modulation schemes can be applied when implementing the present invention. However, the present invention offers a very simple modulation scheme, which is described below and shown in figure 3. In this scheme, the source 30 voltage can operate in three operating conditions that differ from other output frequencies. The first state will be shown as a normal state in which no data is transmitted in this state, the output voltage has the first frequency, for example 50 Hz. The second condition will be shown as the first state data, which is transmitted one data bit having the first value (for example, "1"): in this state, the output voltage has a second frequency, such as 125 Hz, easily distinguishable from the first frequency. The third condition will be shown as the second state data, which is transmitted one data bit having a second value (for example, "0"): in this state, the output voltage has a third frequency, for example, 250 Hz, easily distinguishable from the first and second frequencies.
The purpose of communication, you can define successive time frames of equal length and set the output frequency, DL is each time frame. However, this will require timing and synchronization. In a simple embodiment, the data block length is defined as the period of time, beginning and ending with the zero-crossing, if possible, with a predetermined number of zero-crossing within a given interval. Thus, the data block may have a duration corresponding to the phase of 360° voltage signal, but in the preferred currently embodiment, the data block corresponds to the phase of 180° voltage signal; it not only provides high speed data transfer, but also provides the advantage of ease of decoding.
Figure 3 shows a graph of the output voltage Vs as a function of time for a typical situation. First, the device 20 software control is not sending any data; the control signal Vc to source 30 voltage has a first value that causes the source 30 voltage to operate in the first state indicating that the output voltage Vs has a first frequency, for example 50 Hz. Suppose that at time t0, the device 20 program management is going to transmit data. It generates its control signal Vc source 30 voltage with a second value indicating a data bit "1", and in response, the source 30 voltage, starts the time t1, corresponding to the next zero-crossing, makes the transition to the second state in which it generates the output voltage Vs at the second frequency, in this case, 125 Hz. The source 30 voltage remains in the second state until the next zero crossing at time t2, so that the output voltage Vs corresponds to a half-period or phase 180° at the second frequency. This means that in this example, the interval between two zero-crossing at time t1 and t2 is equal to 4 MS. After the time t2, the voltage source of the 30 ready to obey the next command device 20 software control.
Suppose that the data to be transmitted, include the second bit is "0", as indicated by the third value of the control signal Vc. In response, the source 30 of the voltage, since the time t2 is a transition through zero, makes the transition to the third state in which it generates the output voltage Vs at the third frequency, such as 250 Hz. The source 30 voltage remains in the second state until the next zero-crossing, so that the output voltage Vs shows half of the period or phase of 180° at the third frequency. This means that in this example, the interval between two zero-crossing is equal to 2 MS.
The above procedure continues for all data bits. The figure shows that the mouth of austo 20 software control at time t3, so the source 30 voltage continues to operate in its first state, with the time intervals between transitions through zero, equal to 10 MS. It should be clear that the length of one bit of data may also correspond to n·180°, where n is any real number.
Also, it should be clear that the frequency does not need to be very accurate. For example, in the above example, the frequency range from 100 Hz or lower, the corresponding time intervals of 5 MS or more, may indicate the absence of data; frequency range from 100 Hz to 200 Hz, corresponding to time intervals between 5 MS to 2.5 MS, can point to data of "1", and the frequency range from 200 Hz and above, the corresponding time intervals of 2.5 MS or less, can point to data of "0".
Additionally, to increase the speed of data transfer, you can use more than two different frequencies of data. For example, a set of four possible frequencies of data you can send two bits of data.
Figure 4 shows the block diagram comparable to Fig 1, an electronic driver 200 according to the present invention, illustrating the driver 200 that receives the supply voltage Vs, which is supplied by the source 30 voltage device 100 programming. The driver 200 includes a rectifier 210, such as a diode bridge, the output terminals 211, 212 which is connected to the input terminals 3, 4 driver for receiving the AC voltage Vs from the power source, and output terminals 218, 219 are connected with lines 205, 206 power driver 200. The controller 10, in which the terminals 15, 16 are connected to these lines 205, 206 power supply, receives the rectified voltage, for example, after smoothing filter (not shown), which is intended to remove frequency components.
It is assumed that the controller 10 has an analog input 11 of the data, which is typical for most controllers. Measuring signal representing the rectified voltage is then applied to this analog input 11 of the data. This measuring signal is generated resistive voltage divider composed of two series-connected resistors 221, 222, connected between lines 205, 206 power supply. The controller 10 is configured by programming using the appropriate software, to sample a signal at its input 11 with a suitable high sampling frequency and to process this information to identify the data transferred through the supply voltage, for example, by initially allocating time intervals between zero-crossing. In other words, the controller 10 is designed for demodulation frequency is Tulyaganova supply voltage. Additionally, the controller 10 is designed for processing the thus received data to adjust its settings and/or configurations that should be clear to a person skilled in the technical field.
Alternatively, for example, if the controller does not have analog input data, it is possible that the driver 200 contained additional data processing module for receiving the rectified mains power supply analog input selection bits of data and transmission of data bits to the digital input of the controller. But this option requires additional hardware component and, therefore, is more expensive, while the preferred implementation, discussed above, has the advantage that it can be simply implemented in the software of the controller.
One of the possible embodiments of the present invention, the programming of the controller 10 is open, i.e. without feedback as confirmation. In a preferred embodiment, the controller 10 is able to communicate in the opposite direction of the device 100 programming using a power supply line. When communication can be made simple statement, but it can also be drawn on the status report or a list of tech is related settings. In any case, the electronic driver 200 must have a means of communication.
It is possible, of course, to provide electronic driver device 200 for applying a high frequency communication signal to the power supply voltage Vs, which can be accepted and processed by the device 100 programming. However, this is complicated and expensive. To avoid this, the present invention offers a solution, the advantage is that it can be implemented within the software of the controller 10. In this embodiment, the implementation of outputs 8, 9 electronic driver 200 is connected to a suitable load such as a lamp 2, so that the electronic driver 200 generates the output current and, therefore, consumes the input current from the programming device, and further, the controller 10 is intended to modulate the input current. To be able to detect this modulation of the input current driver, the device 100 programming can be equipped with a current sensor 40 for measuring the output current signal generated at the outputs 108, 109 programming device, and transmitting the measurement signal to the input 24 of the current measurement from the device 20 program management. Specialist in the art it should be clear that the device 20 software control can be performed (programmed) with an option of processing the measurement signal from the sensor 40 current to retrieve data transmitted by the controller 10.
Since this is the modulation current, it is noted that the controller 10 has an output 19, which generates the control signal Sc, which determines the instantaneous value of current supplied to the load 2. Usually electronic driver 200 includes device 230 correction power factor, receiving this control signal, and take all further control current. Since the devices of the PFC is well known, further explanation is not required here. For the subsequent discussion, it is assumed that the control signal Sc is usually a signal of constant value, indicating a constant average current.
Preferably, the modulation current is amplitude modulation. Specialist in the art should know that amplitude modulation can be performed in various ways, and, in principle, all modulation schemes can be applied when implementing the present invention. However, the present invention also offers a very simple modulation scheme described below with reference to figure 5. In this scheme, the modulation includes the suppression of the current at a sufficiently high frequency suppression, for example, 500 Hz. It can also be seen as multiplying by a 500 Hz square wave. Every bit of information and corresponds to one half-cycle of supply voltage, that is, the period between two successive zero-crossing. Per bit, the high-frequency signal suppression is either present or not, which corresponds to two different values for one bit of data that are readily recognizable.
Figure 5 shows a graph of the current consumed from the source 30 voltage, as a function of time, when this graph is a good example, which assumes that the device 100 programming does not transmit data to the electronic driver 200, so that the current has a nominal frequency of 50 Hz. The navigation function of the current through zero is designated as t0, t1, t2, t3, etc. the Time intervals between successive zero-crossing marked as temporary frames. In the time frame between t0 and t3, the controller 10 does not send data to the device 100 programming, thus forming an unperturbed wave current. In the time frame between t3 and t4, the controller 10 transmits one bit of information ("0") by the generation of current pulses: this bit is interpreted as a start bit, the beginning sequence of a predetermined number of bits. In the time frame between t4 and t5, the controller 10 does not generate the current pulses, transmitting one bit of data ("1"), while in the time frame between t5 and t6, the controller 10 transmits one data bit ("0") by generating a pulse current is.
Summarizing, the present invention provides a device 100 programming for programming the controller 10 in the electronic driver 200 that contains the managed source 30 voltage, suitable for generating an alternating voltage and power electronic driver 200 is disabled outlet and a programmable controller 20 to control the source 30 voltage. The device 100 programming is designed to modulate the frequency of the supply order as supply power to the electronic driver 200 and the data programming in the electronic driver 200.
