The detection module is connected to the dual-mode communication module to be tested through the access module. The detection module is used to receive the instructions forwarded by the control module and detect the interface and working status of the dual-mode communication module to be tested according to the instructions.

[0055] Specifically, the dual-mode communication module detection system described in this embodiment is used to detect the dual-mode communication module. The specific detection object can be the dual-mode communication module in the electric energy meter to ensure the ex-factory quality of the electric energy meter and improve its detection efficiency at the same time.

[0056] The detection system described in this embodiment includes a host computer, a control module, an access module, a co-test module, and a detection module. The access module, the co-test module, and the detection module are all connected to the control module. The following will combine Figure 1-11 Describe in detail the connection relationship and functions between the various modules of the dual-mode communication module detection system.

[0057] The control module is used to control the co-test module, the access module, and the detection module, and control the test system to test the dual-mode communication module to be tested. During the test process, the control module is used to send signals to test the dual-mode communication module to be tested.

[0058] It should be noted that the detection system described in this embodiment also includes a host computer. The control module is connected to the host computer through a serial port, used to communicate with the host computer, complete various test tasks, and output instructions to the control module. Among them, the serial port is a DB9 interface. In the actual test process, the host computer is used to send corresponding instructions to the control module, and the control module outputs corresponding signals to the corresponding modules according to the corresponding instructions sent by the host computer, so as to realize the test of the dual-mode communication module to be tested. In this embodiment, the instructions sent by the host computer are divided into power-on instructions, test instructions, and power-off instructions.

[0059] Furthermore, the control module in this embodiment is a main control MCU. The circuit diagram of the control module is as Figure 2As shown, the main control MCU is preferably the GD32F407ZGT6 single-chip microcomputer, which has an ARM-Cortex M4 core, a main frequency of 192MHz, and 144 PIN pins. It has high performance and low power consumption, with rich peripheral interfaces and powerful computing capabilities, enabling easy data exchange and communication with external devices, and providing test guarantees for the detection system described in this embodiment.

[0060] One end of the co-testing module is connected to the access module through an attenuator, and the other end is connected to the control module; the co-testing module sends test signals to the dual-mode communication module to be tested through the attenuator, and the co-testing module cooperates with the control module to perform HPLC tests and RF tests on the dual-mode communication module to be tested.

[0061] Furthermore, the co-testing module includes a co-testing unit and a co-testing unit socket. The co-testing unit is connected to the co-testing unit socket, and the co-testing unit socket is also connected to the control module and the access module respectively. The co-testing unit socket is of the size of a standard single-phase electric energy meter communication module socket, including weak-current terminals and strong-current terminals, and both the weak-current terminals and the strong-current terminals conform to the terminal definitions of the national grid single-phase electric energy meter communication module.

[0062] The strong-current terminals of the co-testing unit socket are connected to the access module through an attenuator, used to send HPLC test signals to the dual-mode communication module to be tested. At the same time, the co-testing unit, in cooperation with the control module, performs HPLC tests (high-voltage power line carrier tests) and RF tests (radio frequency tests) on the dual-mode communication module to be tested. Among them, the HPLC test includes HPLC communication detection and calibration; the RF test includes RF communication detection and calibration. It should be noted that the attenuator set in this embodiment is an HPLC attenuator, and the attenuation value of the attenuator is fixedly set to 60dB, used to attenuate the HPLC test signals sent by the co-testing unit, control the signal strength, ensure the correct range of HPLC signal transmission, and protect circuit components.

[0063] Furthermore, the test system also includes a phase control module, which is respectively connected to the attenuator, the control module, and the access module. After the control module receives the instruction sent by the host computer, the phase control module will control the phase of the dual-mode communication module to be tested accessing the access module according to the instruction forwarded by the control module, and cooperate with the co-testing module to perform HPLC tests and RF tests on the dual-mode communication module to be tested. It should be noted that the phase control module uses multiple relays to control the phase of the dual-mode communication module to be tested accessing the access module, and one or more phases among the three phases A / B / C can be selected to access for testing according to the actual situation, enabling flexible selection of the access phase and ensuring the accuracy of detection.

[0064] The access module is actually a socket for connecting the dual-mode communication module under test, the co-test module, the control module, and the detection module. The access module includes a strong-current terminal and a weak-current terminal. The strong-current terminal of the access module is connected to the strong-current terminal in the co-test unit socket through a phase control unit and an attenuator, and its strong-current terminal is also connected to the control module through a phase control module. The weak-current terminal of the access module is directly connected to the detection module, and can test the interface and working state of the dual-mode communication module under test under the action of the detection module.

[0065] It should be noted that the circuit diagram of the co-test module is as Figure 3 shown. The co-test module includes a connector J8. The RXD pin of the connector J8 is connected to the 136th pin of the control module, and the TXD pin is connected to the 137th pin of the control module for communicating with the control module. The circuit diagram of the attenuator is as Figure 4 shown. The input end of the attenuator is connected to the co-test module, and the output end is connected to the phase control module.

[0066] The circuit diagram of the phase control module is as Figure 5 shown. The phase control module is respectively connected to the attenuator, the control module, and the access module. The phase control module includes separate A-phase unit, B-phase unit, and C-phase unit. One input end of the A-phase unit is connected to the output end of the attenuator, and the other input end is connected to the 65th pin of the control module. The output end is connected to the access unit and finally to the dual-mode communication module under test. One input end of the B-phase unit is connected to the output end of the attenuator, and the other input end is connected to the 66th pin of the control module. The output end is connected to the access unit and finally to the dual-mode communication module under test. One input end of the C-phase unit is connected to the output end of the attenuator, and the other input end is connected to the 67th pin of the control module. The output end is connected to the access unit and finally to the dual-mode communication module under test. It should be noted that the A-phase unit, B-phase unit, and C-phase unit in the phase control module are all connected to the strong-current terminal of the access module.

[0067] The circuit diagram of the access module is as Figure 6 shown. The access module includes a connector J6. The 7th pin of the connector J6 is connected to the 96th pin of the control module, the 8th pin is connected to the 97th pin of the control module, the 9th pin is connected to the 88th pin of the control module, the 10th pin is connected to the 87th pin of the control module, the 11th pin is connected to the 56th pin of the control module, and the 12th pin is connected to the 57th pin of the control module. The access module also includes a strong-current terminal interface J7. The A-phase unit, B-phase unit, and C-phase unit in the phase control module are all connected to the J7 of the access module.

[0068] As an optional implementation manner, the detection module includes a power control unit and a communication management unit; the power control unit is connected to the dual-mode communication module to be tested through an access module, and is used for powering on and off the dual-mode communication module to be tested; the communication management unit is connected to the dual-mode communication module to be tested through an access module, and is used for communicating with the dual-mode communication module to be tested, sending the instructions forwarded by the control module to the dual-mode communication module to be tested, and enabling the dual-mode communication module to be tested to enter the test state.

[0069] Specifically, the function of the power control unit is to be able to power on and off the dual-mode communication module to be tested. When the host computer sends a power-on instruction to the control module, the control module will send a power-on signal to the power control unit. At the same time, the power control unit powers on the dual-mode communication module to be tested through the access module. After power-on, the host computer can send different test instructions to the control module according to different test items, and the control module controls the corresponding test units in the detection module to test the dual-mode communication module to be tested. After the dual-mode communication module to be tested completes the corresponding test, the host computer will send a power-off instruction, and the control module controls the power control unit to power off to complete the test of the dual-mode communication module to be tested. After the test of the dual-mode communication module to be tested is completed, the control module will receive the corresponding test data and finally send it to the host computer.

[0070] The communication management unit communicates with the serial port of the dual-mode communication module to be tested through the access module, and is used for forwarding the signals sent by the control module to enable the dual-mode communication module to be tested to enter the test state. After the host computer sends a power-on instruction to the control module to power on the dual-mode communication module to be tested, the host computer will send a second test instruction to the control module. Since the communication management unit is connected to the serial port of the dual-mode communication module to be tested, the communication management unit will forward the corresponding test signals to the dual-mode communication module to be tested and enable the dual-mode communication module to be tested to enter the test state. Among them, after the control module receives the corresponding test instructions, they will all be forwarded to the dual-mode communication module to be tested through the communication management unit, which can ensure the normal forwarding of test data and accurately test different items of the dual-mode communication module to be tested.

[0071] Among them, the second test instruction is used to control the detection module to perform tests. The second test instruction includes an IO test instruction, a power consumption test instruction, a capacitance test instruction, and an Ethernet test instruction. It should be noted that the IO test instruction, the power consumption test instruction, the capacitance test instruction, and the Ethernet test instruction correspond to the IO detection unit, the power consumption detection unit, the capacitance detection unit, and the Ethernet detection unit respectively, and are respectively used to control the IO detection unit, the power consumption detection unit, the capacitance detection unit, and the Ethernet detection unit to detect the IO interface, the power consumption state, the charge and discharge state, and the Ethernet interface of the dual-mode communication module to be tested.

[0072] As an alternative embodiment, the detection module further includes an IO detection unit and a power consumption detection unit; the IO detection unit is connected to the dual-mode communication module to be tested through an access module for testing the IO interface of the dual-mode communication module to be tested; the power consumption detection unit is connected to the dual-mode communication module to be tested through an access module for detecting the power consumption status of the dual-mode communication module to be tested.

[0073] Specifically, the IO detection unit is connected to the dual-mode communication module to be tested through an access module. The main functions of the IO detection unit include data acquisition and transmission, signal conversion, etc. It is responsible for collecting corresponding data from the dual-mode communication module to be tested to test the IO interface of the dual-mode communication module to be tested, confirm whether the IO interface of the dual-mode communication module to be tested is normally connected, and determine whether its IO interface can accurately transmit the corresponding data.

[0074] The power consumption detection unit is used to detect the power consumption status of the dual-mode communication module to be tested. It can measure the power consumption of the dual-mode communication module to be tested, measure its power, voltage, current and other parameters, and can also monitor and analyze the power, voltage, current and other parameters of the dual-mode communication module to be tested to confirm whether the power consumption of the dual-mode communication module to be tested is within a reasonable range.

[0075] Specifically, the power consumption detection unit can perform overall machine current detection and voltage detection on the dual-mode communication module to be tested. Figure 7 is a circuit schematic diagram for overall machine current detection, which includes an integrated chip U5. The first pin of the integrated chip U5 is connected to the twentieth pin of the control module, and the third and fourth pins are connected to the first pin of the connector J6 in the access module. The circuit diagram of voltage detection is as Figure 8 shown.

[0076] It should be noted that when detecting the power consumption status, the power consumption status includes dynamic power consumption and static power consumption. In addition to being able to detect the power consumed by the dual-mode communication module to be tested during state switching, the power consumption detection unit can also detect the power consumed by the dual-mode communication module to be tested in a stable state. And it can judge whether its dynamic power consumption and static power consumption are within a reasonable range. In this embodiment, the reasonable ranges of dynamic power consumption and static power consumption are not limited, and can be limited according to industry standards during actual detection.

[0077] As an alternative embodiment, the detection module further includes a capacitance detection unit and an Ethernet detection unit; the capacitance power consumption unit is connected to the dual-mode communication module to be tested through an access module for detecting the charge and discharge status of the dual-mode communication module to be tested; the Ethernet detection unit is connected to the dual-mode communication module to be tested through an access module for detecting the Ethernet interface of the dual-mode communication module to be tested.

[0078] The capacitance detection module is connected to the dual-mode communication module to be tested through the access unit. It is used to detect the charging and discharging of the supercapacitor in the dual-mode communication module to be tested, and to determine whether the connection of the supercapacitor is normal and whether its capacitance is within a reasonable range.

[0079] The capacitance detection module can detect the capacitance charging current and capacitance discharging of the dual-mode communication module to be tested. Figure 9 As shown in the circuit schematic diagram for capacitance charging current detection, it includes an integrated chip U7. The first pin of the integrated chip U7 is connected to the twenty-first pin of the control module, and the third and fourth pins are used to output the 12VCHARGE signal to detect the charging current of the dual-mode communication module to be tested. Figure 10 As shown in the circuit schematic diagram for capacitance discharging detection, when detecting the capacitance discharging, it is respectively connected to the twenty-eighth pin and the fiftieth pin of the control module, and is used to detect the capacitance discharging of the dual-mode communication module to be tested.

[0080] The Ethernet detection unit is connected to the dual-mode communication module to be tested through the access unit. It is used to detect whether the Ethernet interface connection of the dual-mode communication module to be tested is normal. The circuit diagram of the Ethernet detection unit is as Figure 11 shown. It includes an integrated chip U2. The third, fourth, and fifth pins of the integrated chip U2 are respectively connected to the seventieth, seventy-third, and seventy-fourth pins of the control module.

[0081] The above describes multiple units of the detection module and provides a detailed explanation of the functions of the multiple units in the detection module. In this embodiment, the setting of the detection module can detect different functions or corresponding interfaces of the dual-mode communication module to be tested. The data obtained after the detection can effectively support the judgment of whether the dual-mode communication module can leave the factory, improve the detection efficiency of the dual-mode communication module to be tested, and improve the detection accuracy.

[0082] It should be noted that the instructions sent by the host computer all use the same communication protocol, and the formats of the test instructions are the same. After receiving the test instructions, the serial port of the control module can process the data and forward the instructions, and the corresponding units in the detection module can quickly respond to the corresponding test instructions.

[0083] As an alternative embodiment, the detection system further includes a power supply module, which is respectively connected to the co-test module, the control module, the detection module and the access module, and is used to supply power to the co-test module, the control module, the detection module and the access module. Specifically, the power supply module is used to input a 12VDC power supply, and after step-down, it supplies power to the co-test module, the control module, the detection module and the access module, providing effective support for the normal operation of the co-test module, the control module, the detection module and the access module.

[0084] As an alternative embodiment, the detection system further includes a mains control unit, which is respectively connected to the control module, the co-test module and the access module, and is used to perform zero-crossing signal detection on the dual-mode communication module to be tested connected to the access module. One end of the mains control unit is connected to the control module and is used to receive the signal sent by the main control module. The other end of the mains control unit is respectively connected to the co-test module and the access module. When the mains control unit is connected to the access module, it uses the same connection path as the co-test module and the access module. In this embodiment, the mains control unit uses a relay, which can control the access and disconnection of the mains power and is used to detect the zero-crossing signal of the dual-mode communication module to be tested. The zero-crossing signal is a pulse signal generated by a zero-crossing detection circuit. A pulse signal is generated when the voltage of each mains power drops to 0V in each cycle, and the frequency is 50Hz. In this embodiment, detecting the zero-crossing signal of the dual-mode communication module to be tested can detect the accuracy of the zero-crossing signal frequency of the dual-mode communication module to be tested and can determine whether the zero-crossing detection circuit in the dual-mode communication module to be tested is normal.

[0085] The detection system described in this embodiment includes a host computer, a control module, an access module, a co-test module and a detection module. The host computer can send corresponding instructions to the control module, and the control module controls the co-test module and the detection module to test the dual-mode communication module to be tested connected to the access module. According to the test requirements of the dual-mode communication module, multiple test items are integrated into a system and are controlled by a main control MCU, which can save test time, reduce costs and improve detection efficiency.

[0086] The embodiment is only a special case and does not indicate that the present invention has only such an implementation manner.

[0087] Embodiment Two:

[0088] As Figure 12 shown, the present invention also provides a method for detecting a dual-mode communication module, which is applied to the dual-mode communication module detection system of Embodiment One and includes:

[0089] S10. The host computer sends a power-on instruction to the control module, and the control module controls the detection module to power on the dual-mode communication module to be tested according to the power-on instruction;

[0090] S20. The host computer sends a test instruction to the control module to put the dual-mode communication module under test into the test mode. Meanwhile, the accompanying test module and the detection module test the dual-mode communication module under test according to the test instruction to complete the corresponding test items. Among them, there are multiple test instructions, and each test instruction corresponds to a different test item.

[0091] S30. The host computer sends a power-off instruction to the control module. The control module controls the detection module according to the power-off instruction to cut off the power supply of the dual-mode communication module under test and outputs the test result.

[0092] In this embodiment, the host computer sends instructions to the control module, and the control module forwards the instructions to control different modules or units to test the dual-mode communication module. Specifically, the instructions include a power-on instruction, a test instruction, and a power-off instruction.

[0093] When starting the test, the host computer first sends a power-on instruction to the control module, and the control module powers on the dual-mode communication module under test to supply power to the dual-mode communication module under test, providing a power supply basis for subsequent tests. The specific process is that the host computer first sends a power-on instruction to the control module, and the control module sends a signal to the power control unit in the detection module, and the power control unit powers on the dual-mode communication module under test, and finally the dual-mode communication module under test is successfully powered on.

[0094] After the dual-mode communication module under test is powered on, the host computer will send the corresponding test instruction to the control module, and the control module will detect the dual-mode communication module under test connected to the access module according to the test instruction sent by the host computer. The host computer sends a test instruction to the control module, and the control module will transmit the corresponding instruction to the dual-mode communication module under test through the communication management unit in the detection module, so that the dual-mode communication module under test enters the test mode. Meanwhile, the corresponding units in the accompanying test module and the detection module will test the dual-mode communication module under test according to the test instruction to complete the corresponding test items, including:

[0095] The host computer sends a first test instruction to the control module, and the control module controls the accompanying test module to perform HPLC test and RF test on the dual-mode communication module under test based on the first test instruction.

[0096] The host computer sends a second test instruction to the control module, and the control module controls the detection module to test the dual-mode communication module to be tested based on the second test instruction. Among them, the second test instruction includes an IO test instruction, a power consumption test instruction, a capacitance test instruction, and an Ethernet test instruction. The IO test instruction, the power consumption test instruction, the capacitance test instruction, and the Ethernet test instruction are respectively used to control the IO detection unit, the power consumption detection unit, the capacitance detection unit, and the Ethernet detection unit in the detection module to detect the IO interface, the power consumption state, the charge and discharge state, and the Ethernet interface of the dual-mode communication module to be tested.

[0097] In this embodiment, the co-testing module and the detection module can perform different tests on the dual-mode communication module to be tested.

[0098] The co-testing module is connected to the access module through an attenuator and a phase control module, and the access unit is connected to the dual-mode communication module to be tested. The co-testing module can perform HPLC tests and RF tests on the dual-mode communication module to be tested under the action of the control module. When it is necessary for the co-testing module to test the dual-mode communication module to be tested, the host computer sends a first test instruction to the control module, and the control module controls the co-testing module to test the dual-mode communication module to be tested based on the first test instruction.

[0099] The detection module is connected to the dual-mode communication module to be tested through the access module. In addition to including a power control unit for powering on the dual-mode communication module to be tested, the detection module also includes a communication management unit, an IO detection unit, a power consumption detection unit, a capacitance detection unit, and an Ethernet detection unit. The IO detection unit, the power consumption detection unit, the capacitance detection unit, and the Ethernet detection unit can detect the IO interface, the power consumption state, the charge and discharge state, and the Ethernet interface of the dual-mode communication module to be tested according to the second test instruction sent by the host computer.

[0100] It should be noted that the second test instruction is sent to the dual-mode communication module to be tested through the communication management unit, so that the dual-mode communication module to be tested starts corresponding work according to different second test instructions, and at the same time enables the IO detection unit, the power consumption detection unit, the capacitance detection unit, and the Ethernet detection unit to detect the IO interface, the power consumption state, the charge and discharge state, and the Ethernet interface of the dual-mode communication module to be tested. The second test instruction includes an IO test instruction, a power consumption test instruction, a capacitance test instruction, and an Ethernet test instruction. The corresponding test instruction can activate the corresponding test unit in the detection module and enable the units in the dual-mode communication module to be tested, facilitating the testing of the dual-mode communication unit to be tested.

[0101] Finally, after completing the corresponding test items, the host computer will send a power-off command to the control module, and the control module will power off the dual-mode communication module to be tested. The specific process is that the host computer first sends a power-off command to the control module, and the control module sends a signal to the power control unit in the detection module, and the power control unit powers off the dual-mode communication module to be tested.

[0102] The dual-mode communication module detection method described in this embodiment can detect multiple different test items of the dual-mode communication module to be tested on the same detection system, integrate multiple different test items, and can detect the dual-mode communication module more efficiently, improving the detection efficiency and ensuring the detection quality.
