[0034] Refer to the attached Figure 1 As shown, the micro-power wireless simulation test system of the present invention includes a computer simulation test device and a test transceiver connected thereto.

[0035] The test transceiver connects to the computer simulation test device via a USB interface and is also wirelessly connected to a matching concentrator module, which is connected to the concentrator. Specifically, the test transceiver and concentrator module are connected via a GFSK, OOK, NB-IoT, LoRa, or Bluetooth wireless channel. The test transceiver, through its wireless connection to the concentrator module, provides a transmission channel, interacts with the concentrator module, and is used to receive routing path data for each node in the concentrator network after networking with the concentrator, and transmit this data to the computer simulation test device.

[0036] This computer simulation test device simulates the electricity consumption collection process of the meter module, tests the interaction between the transceiver and the concentrator module, and finally displays the test results. The computer simulation test device includes a transceiver module, a configuration module, a data processing module, a routing algorithm module, a network module, a display module, and a storage module.

[0044] The data processing module is used to parse the data transmitted by the transceiver module according to the protocol configured by the configuration module, and to frame the parsing result and send it to the display module.

[0045] The routing algorithm module is used to derive the internal routing path for each node using the data configured by the configuration module, the internal routing algorithm, and the field strength information of each node, and transmit the resulting internal routing path to the display module. The internal routing path for each node generated by the routing algorithm module can be used as a quality evaluation criterion for evaluating the routing algorithm of the concentrator module.

[0046] This display module visually displays the data analysis results sent by the data processing module in a table or topology diagram format. This includes the routing paths for each node derived by the concentrator's routing algorithm, as well as the internal routing paths for each node derived and transmitted by the routing algorithm module, and compares these two routing paths. This display module can also display networking, meter reading time, and frames related to node networking and meter reading, as well as other service information such as event reporting and broadcast time synchronization.

[0047] The network module is used to connect to the concentrator via a network cable to send the address of each meter file, frozen data on the reading day, set time, etc. configured by the configuration module to the concentrator. The network module is used to simulate the function of the master station.

[0048] The storage module is used to store the log records, received and sent data and result comparison of the computer simulation test device.

[0052] (3) sending the addresses of the table files simulated by the configuration module to the concentrator through the network module, and the concentrator starts the networking command;

[0053] (4) After the concentrator is networked, the routing path data of each node obtained by the concentrator routing algorithm is received through the test transceiver device, and then the data is transmitted through the transceiver module and analyzed by the data processing module. Finally, the routing path of each node is displayed through the display module. At the same time, the routing algorithm module obtains the internal routing path of each node through the data configured by the configuration module, the internal routing algorithm and the field strength information of each node, and transmits the obtained internal routing path to the display module. The display module displays the comparison of the routing path of each node obtained by the concentrator routing algorithm analyzed by the data processing module and the internal routing path of each node sent by the routing algorithm module in the form of a table or a topology diagram. The comparison result is indirect and intuitive.

[0054] (5) The node configuration is also changed in real time through the configuration module, and then the abnormal condition test of each meter is implemented according to steps (3) and (4), such as meter failure, meter error response, meter delayed response, etc. Other items are also tested according to needs, such as meter reading, full network perception, broadcast time calibration, etc.

[0055] (6) The storage module is used to record and store the operating steps, received and sent data, and comparison data of the results during the test process for subsequent analysis.
