The message interaction can be information such as module reset initialization, starting identification, module manufacturer version reading and the like, or can also be information such as module sub-node (such as electric energy meter) parameter downloading, meter reading and the like.
In the existing electricity consumption information acquisition system, a palm computer is also called as an electric power PDA or a PDA, and the hardware of the palm computer is formed by combining all or part of a human-computer interaction unit, an infrared port, an RS485 port and a remote communication unit. In the fault diagnosis device shown in fig. 1, since the interface 3 of the concentrator telecommunication module includes a GPRS port and an ethernet port, the function of a telecommunication unit in a palm computer can be realized, and therefore, the fault diagnosis device shown in fig. 1 can be considered to have all hardware units and interfaces constituting the palm computer, and a software part is the same as the palm computer, and only the existing palm computer related programs need to be written and burned, data messages are generated through user interfaces such as a keyboard or a touch screen in a man-machine interaction unit, and are transmitted and received through a communication interface unit, so that the palm computer in the electricity consumption information acquisition system can be replaced.
In addition, in the electricity consumption information collection system, in order to simulate the master station function, communication protocols such as "QGDW 1376.1-2009/13 master station and collection terminal communication protocol", "QGDW 1376.2-2009/13 concentrator local communication module interface protocol", and "DL/T645-2007 communication protocol" are generally run on a notebook computer to realize the simulation, and then data messages are formed through a human-computer interaction interface and are transmitted and received through a communication interface unit. However, the field concentrator and the electric energy meter debugging communication port is usually an infrared port, an RS485 port or an RS232 port, while the notebook computer generally only supports an RS232 and ethernet interface, does not support an RS485 port, WiFi or GPRS/CDMA communication, is not highly versatile, generally requires communication conversion interface conversion or external expansion when the analog master station communicates with the concentrator/electric energy meter, and the notebook computer itself does not have a communication unit for remote connection and is heavy to carry, so the notebook computer is usually replaced by a palm computer or a fault diagnosis device provided by the embodiment of the present invention.
In the electricity consumption information acquisition system, the reading controller is equipment provided by a concentrator and an electric energy meter local communication module manufacturer and provided with a concentrator local communication module and an electric energy meter local communication module communication link on which signal messages are received, intercepted, modulated and demodulated. One end of the controller is an RS232 port for connecting a palm computer or a notebook computer, and the other end is connected to a communication link (usually a power line) between the concentrator local communication module and the electric energy meter local communication module. The palm computer or the notebook computer sends the communication message to the copy controller through the RS232 port, and the copy controller is used for modulating the communication message and then sending the modulated communication message to a power line or other communication links between the concentrator local module and the electric energy meter local module. Or after the copy controller is connected to a communication link between the concentrator local communication module and the electric energy meter local communication module, the received signal is converted into a data message through the signal demodulation circuit, and the data message is sent to the palm computer or the notebook computer through the RS232 port. By utilizing the fault detection equipment provided by the embodiment of the invention, a copy controller in the power utilization information acquisition system can be simulated: the concentrator local communication module is inserted into the concentrator local communication module interface 1, and after the electric energy meter local communication module is inserted into the electric energy meter local communication module interface 2, a message can be received and transmitted on a communication link, modulation and demodulation are performed, and the message on the communication link is intercepted (for example, the inserted local communication module is enabled or configured as a copy controller module of a module manufacturer), so that the copy controller can be replaced. In addition, the local communication module interface 1 of the concentrator and the local communication module interface 2 of the electric energy meter on the fault diagnosis device in the embodiment of the invention are both UART signals with TTL level, and the hardware connection is equal to the UART signal with RS232 level between the copy controller and the palm computer or the notebook computer.
The fault diagnosis equipment provided by the embodiment of the invention can identify the phase information and the transformer area information of the electric energy meter to be detected in the electricity information acquisition system. In specific implementation, the fault device and the electric energy meter to be tested provided by the embodiment of the present invention are connected to the same power cable (which may be a three-phase power cable or a single-phase power cable), and then the second station area identification module 42 is plugged into the concentrator local communication module interface 1. Running the three-phase station identification software in the processor 9 enables the device to have the function of identifying the host side (sender) and the slave side (receiver) of the three-phase station simultaneously. The processor 9 (host end) sends the station area identification command to the second station area identification module 42 through the weak current terminal of the concentrator local communication module interface 1, and after the second station area identification module 42 receives the station area identification command, the first station area identification module 41 is controlled to send out the modulated power frequency zero-crossing signal through the extended pin of the concentrator local communication module interface 1. The concentrator local communication module interface 1 (from the machine end) transmits the power frequency zero-crossing signal to the second station area identification module 42 through the strong current terminal, and the second station area identification module 42 demodulates the power frequency zero-crossing signal and then transmits the demodulated power frequency zero-crossing signal to the processor 9 through the weak current terminal, so that the phase information and the station area information of the electric energy meter to be detected are obtained and transmitted to the touch screen for display. If the processor 9 does not receive the demodulated power frequency zero-crossing signal sent by the concentrator local communication module interface 1 within a preset time (for example, 6 seconds), it indicates that the concentrator local communication module interface 1 and the processor are not in one station area.
The power frequency zero-crossing signal adopted by the embodiment of the invention is the power frequency carrier modulation signal, and can technically ensure the long-distance signal transmission of the same line and cannot be transmitted to other lines, so that all users in a distribution room can be quickly, accurately and reliably identified, no misjudgment occurs, no user which cannot be identified exists, and one-time successful identification is ensured.
By utilizing the fault diagnosis equipment provided by the embodiment of the invention, the fault detection can be carried out on the electric energy meter to be detected and the local communication module thereof in the electricity utilization information acquisition system.

In specific implementation, after the power consumption information acquisition system fault diagnosis device is connected with the electric energy meter to be detected according to the connection mode, a QGDW1376.2-2013 concentrator local communication module interface protocol and a DL/T645-2007 communication protocol are operated on the device, and the processor 9 actively sends a message to a corresponding port of the connected electric energy meter to be detected through the infrared port 7, or the RS485 port, or the electric energy meter local communication module interface 2 to detect the communication port and the working condition data of the electric energy meter to be detected.
The invention only takes the detection of the local communication function of the electric energy meter to be detected as an example, and explains the electric energy meter communication detection function of the equipment: the processor 9 sends a data message to a concentrator local communication module (or a copying controller module) inserted in the concentrator local communication interface 1, the concentrator local communication module (or the copying controller module) modulates the received data message and sends the modulated data message to a communication link, the local communication module of the electric energy meter to be tested demodulates the modulated data message from the communication link and sends a demodulation signal to the electric energy meter to be tested, and the electric energy meter to be tested normally receives the demodulation signal and then sends a response communication message to the local communication module of the electric energy meter to be tested for demodulation, and finally sends the response communication message to the communication link. The concentrator local module or the meter reading controller module inserted in the concentrator local communication module interface 1 of the device demodulates signals on a communication link and sends the demodulated signals to the processor 9, and the processor 9 judges that the communication function of the electric energy meter to be tested is normal.
In addition, the device can also simulate the communication function of the electric energy meter, when the device works in a simulated electric energy meter form, after the infrared port 7, the RS485 port 5 and the electric energy meter local communication module interface 2 of the device receive communication messages, the device can respond to different contents to generate corresponding response communication messages according to user configuration, and the response communication messages can be consistent with the actual electric energy meter.
