[0029] In order to better understand the concept of the present invention, it is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 The detection device shown includes a host module, an external test module and an interface module, wherein the host module, the external test module and the interface module can be connected and combined via a data line to perform detection of different indicators.

[0031] The above-mentioned external test module is mainly used for the detection of standing wave ratio, resistance, current and voltage; the interface module is mainly used for connecting cables, transmitters or receivers of different interfaces in the vehicle-mounted command information system.

[0032] The external test module completes the detection of standing wave ratio, resistance, current and voltage and displays the data through the host module; the detection of cables, transmitters or receivers is completed and displayed by the host module.

[0033] The circuit schematic diagram for realizing the above-mentioned various detections is as follows Figure 2 As shown:

[0034] The host module includes a display control unit, a micro control unit, a digital-to-analog conversion unit, an operational amplifier unit, a power amplifier unit and a power supply;

[0035] When the host module is connected to the external test module, the power supply supplies power to both the host module and the external test module, and connects the display control unit and the external test module signals through the data line.

[0036] The external test module includes a standing wave ratio detection unit and a multimeter unit. The standing wave ratio detection unit can be used to detect the standing wave ratio of radio frequency components (such as antennas) in the vehicle-mounted command information system. The multimeter unit has the ability to detect resistance, voltage and current, and short circuit detection. It can also be used to check the quality of devices such as diodes.

[0037] Since the standing wave ratio detection will be interfered by other detection units and will also interfere with other detection units, electromagnetic shielding and anti-interference design are adopted to enhance the electromagnetic compatibility between the standing wave ratio detection unit and the multimeter unit, ensuring that each circuit unit does not interfere with other circuit units when working.

[0038] In addition to displaying the test results of the external test module, the display and control unit can also switch between the standing wave ratio test unit and the multimeter unit under different test requirements.

[0039] The interface module integrates different types of interfaces, which can be specifically divided into cable interface, receiver interface, and transmitter interface.

[0040] After the interface module is connected to the host module, performance testing can be performed on the cables, receivers, and transmitters connected to the interface module.

[0041] The specific detection of the cable, receiver and transmitter is realized through the micro control unit and digital-to-analog conversion unit in the host module.

[0042] Cable detection mainly involves the on-off and short-circuit detection of the cable. The two ends of the cable are respectively inserted into the cable interfaces of the corresponding models, and the detection is realized through the IO port of the microcontroller unit. The detection result is sent by the microcontroller unit to the display control unit for display.

[0043] The detection of the receiver mainly involves the detection of the quality of the receiver and the AC impedance. The receiver connector is connected to the receiver interface, and a digital signal is sent to the digital-to-analog conversion unit through the microcontroller unit. The digital-to-analog conversion unit converts the digital signal into an analog signal and transmits it to the receiver through the power amplifier. When detecting the quality of the receiver, the microcontroller unit sends an audio signal. If the receiver can play normally, it means that the receiver is working normally. In addition to detecting the quality of the receiver, the analog signal can also be fed back to the digital-to-analog conversion unit through the receiver. The digital-to-analog conversion unit converts the analog signal into a digital signal and sends it to the microcontroller unit for processing to detect the AC impedance of the receiver. The display unit displays the detection result.

[0044] The detection of microphone mainly involves the detection of the quality of microphone. The microphone connector is connected to the microphone interface. The operator speaks to the microphone. The microphone amplifies the analog signal through the operational amplifier and then processes it into a digital signal by the digital-to-analog conversion unit. The microcontroller then processes the digital signal and displays the on and off status of the microphone on the display unit. The microcontroller can also send a signal to the microphone through the digital-to-analog conversion unit and receive the feedback signal from the microphone to detect the AC impedance of the microphone.

[0045] When testing the components to be tested connected to the above-mentioned cable interface, microphone interface, and receiver interface, switching is required, and the switching is also performed through the display and control unit. Therefore, the interface module and the external test module can be connected to the host module at the same time. When it is necessary to switch to the required detection function, the switch can be performed through the display and control unit. Of course, the interface module and the external test module can also be connected to the host module separately. At this time, the corresponding detection mode is switched for the connected module through the display and control unit.

[0046] Since cables, receivers, and transmitters also have different types of connectors, the cable interface, receiver interface, and transmitter interface can be set up with multiple models of interfaces as needed. For example, the cable interface can be set up with interfaces such as power supply, audio, and data communication (such as YS2J7MJ, FQ14-Z, JY27513E12F04PN, etc.), and the transmitter and receiver interface can be matched and set up according to the status of the equipment in service. When the same type of interface (this type of interface refers to the cable interface, the receiver interface, and the transmitter interface) has multiple models, it is also necessary to switch between the interfaces of each model in order to detect the component to be tested connected to the interface. Therefore, when the same type of interface is set up with multiple models or multiple groups, it is also necessary to set up a matrix switch for switching interfaces in the host module, and switch different signal interfaces through the microcontroller unit, so that the interface connected to the component to be tested is in a test state to test the component to be tested. Therefore, according to this embodiment, it can be seen that since the interface types include cable interface, receiver interface, and transmitter interface, and each type of interface is provided with a group of different models, the matrix switch is also provided with three interfaces corresponding to each type, respectively, to switch the various models of interfaces under each type of interface.

[0047] It should also be noted that when connecting a matrix switch to the microphone interface, since the matrix switch has a noise effect on the microphone, it is best to set the matrix switch at the output end of the op amp. Therefore, the number of op amps needs to correspond to the number of microphone interfaces, that is, each microphone interface needs to be configured with an op amp.

[0048] The above-mentioned power source is a lithium battery, which supplies power to the display control unit, micro control unit, digital-to-analog conversion unit, power amplifier unit, operational amplifier unit, matrix switch, interface module, and external test module. When the display control unit switches the detection function, on the one hand, the internal program is switched to the corresponding detection program, and on the other hand, the power supply is connected to the corresponding module or unit to put it in the detection state, thereby completing the detection.

[0049] The above-mentioned standing wave ratio detection unit for detecting the RF unit includes an RF input, a frequency load, an RF output, a detection unit, a control processing unit and a communication interface. The RF input and RF output are collected by the detection unit and then transmitted to the control processing unit for signal processing, and the processed signal is transmitted to the display control unit through the communication interface for display.

[0050] The multimeter unit includes a function conversion circuit, a range conversion circuit, and an analog-to-digital converter. The measured data is converted into digital signals by the analog-to-digital converter through the function conversion circuit and the range conversion circuit and sent to the display control unit for display.
