[0021] figure 1 It is a schematic structural diagram of a local communication reliability test system for electricity usage information collection according to an embodiment of the present invention. The electricity usage information collection local communication reliability test system includes a host computer 11, a master communication unit 12, and at least one slave communication unit. In this embodiment, the slave communication unit 13 and the slave communication unit 14 will be described as an example. It should be noted that when testing the reliability of the actual application of low-voltage power carrier communication in the field, the master communication unit 12, the slave communication unit 13, and the slave communication unit 14 adopt low-voltage power carrier communication modules; When the power wireless communication is reliable in actual field application, the master communication unit 12, the slave communication unit 13, and the slave communication unit 14 adopt micro-power wireless communication modules. The low-voltage power carrier communication module and the micro-power wireless communication module are both existing structures, and will not be repeated here.

[0022] Specifically, the host computer 11 is connected to the main communication unit 12, and is suitable for configuring test parameters and source test data, and controls the main communication unit 12, the slave communication unit 13, and the slave communication unit 14 to locally The communication mode is used to communicate, receiving and analyzing the target test data to obtain the communication status of the current channel. In this embodiment, the host computer 11 may be connected to the main communication unit 12 through a USB interface. Further, the host computer 11 includes a configuration module, a control module, and a processing module.

[0023] The configuration module is suitable for configuring test parameters and source test data according to the requirements input by the user. Through the visual input interface provided by the host computer 11, the user can set test parameters and source test data according to actual needs. The test parameters include local communication mode, message length, repeated data transmission times, data transmission path, and test times. In this embodiment, the maximum message length can be set to 250 Bytes, and the minimum can be set to 1 Byte. The data transmission path can be set from the master communication unit 12 directly to each slave communication unit, or it can be set as a slave communication unit. The master communication unit 12 passes through the middle slave communication unit to the next slave communication unit. The source test data may be directly input to the configuration module by the user, or may be randomly generated by the configuration module.

[0024] The control module is adapted to send the source test data to the master communication unit according to the configured test parameters, and wait to receive the response data from the slave communication unit forwarded by the master communication unit. After setting the test parameters and the source test data, the configuration module sends the source test data to the main communication unit 12 in the form of a message. The master communication unit 12 sends the source test data to the designated slave communication unit in the form of a message according to the configured local communication mode and data transmission path. After the designated slave communication unit receives the data sent by the master communication unit 12, it returns response data according to the original transmission path specified by the master communication unit 12, and the content of the response data is the instruction requested by the master communication unit 12 Make sure. The instruction requested by the main communication unit 12 can be set according to the actual needs of the user, which is not limited in this embodiment. During the data transmission process, the main communication unit 12 extracts the communication parameters of the current channel to obtain target test data, and feeds back the target test data to the host computer 11, and the target test data includes the From the response data of the communication unit, the communication parameters include signal quality and communication response time.

[0025] The processing module is adapted to analyze the target test data to obtain the communication status of the current channel, the communication status including the packet loss rate, signal strength, and communication conditions of different communication data loads. Further, the host computer 11 can provide the tester with the communication status of the current channel in an intuitive manner through a friendly visual interface.

[0026] Based on the above-mentioned electricity usage information collection local communication reliability test system, the embodiment of the present invention also provides a electricity usage information collection local communication reliability test method. figure 2. The method for testing the reliability of local communication for collecting electricity information includes:

[0027] Step S1: Install the master communication unit at the installation position of the electricity usage information collection terminal, and install the slave communication unit at the installation position of the smart meter. Further, when there are multiple slave communication units, the installation location of each slave communication unit is a randomly selected smart meter installation point.

[0028] Step S2, configure test parameters and source test data in the host computer. As mentioned above, through the visual input interface provided by the host computer 11, the user can set test parameters and source test data in advance according to actual needs. The test parameters include local communication mode, message length, number of repeated data transmissions, data Transmission path and number of tests.

[0029] Step S3: Input a test command in the upper computer, so that the upper computer controls the master communication unit to send the source test data to the slave communication unit to obtain the target test data in the current communication mode. After the communication channel is established, the host computer 11 sends the source test data to the main communication unit 12 in the form of a message, and the main communication unit 12 tests the source according to the configured local communication mode and data transmission path. The data is sent to the designated slave communication unit in the form of messages. After the designated slave communication unit receives the data sent by the master communication unit 12, it returns response data according to the original transmission path designated by the master communication unit 12. During the data transmission process, the main communication unit 12 extracts the communication parameters of the current channel to obtain the target test data, and feeds back the obtained target test data to the host computer 11, and the host computer 11 responds to the target test data. Perform analysis to obtain the packet loss rate, signal strength, and communication conditions of different communication data loads.

[0030] Taking testing the reliability of the actual application of low-voltage power carrier communication in the field as an example, the master communication unit 12, the slave communication unit 13, and the slave communication unit 14 are all low-voltage power carrier communication modules.
