Description

Technical Field

[0001] This invention relates to the field of communication equipment, and more specifically to a fully automated testing adapter. Background Technology

[0002] Currently, almost all communication devices undergo performance / functional testing using manual or semi-automatic methods. Manual testing is labor-intensive and extremely time-consuming. Semi-automatic testing involves connecting all the communication devices to be tested (such as spectrum analyzers, signal generators, and audio analyzers) to the host via GPIB or TCP protocol interfaces. The control protocols of the communication devices interact with the host through the network port, and the audio ports of the communication devices require a test box to connect to the corresponding test equipment. During testing, the test box needs to be constantly adjusted manually to change the corresponding audio data and audio channels to meet the performance testing requirements. Call functionality testing requires a person to conduct a call through a microphone and audio amplification. However, this semi-automatic testing method does not completely free up testers, and human intervention during testing may introduce errors in performance test indicators. Furthermore, call functionality testing involves human interaction during both the call and reception, leading to individual differences and making it difficult to accurately distinguish between good and bad performance.

[0014] The embodiments of the present invention will be described in detail below with reference to examples. However, those skilled in the art will understand that the following examples are only for illustrating the present invention and should not be regarded as limiting the scope of the present invention.

[0015] refer to Figure 1 A fully automatic test adapter is used to perform performance or functional tests on communication equipment in conjunction with a test host and test instruments and equipment. The fully automatic test adapter includes digital circuits and audio circuits.

[0016] The digital circuit is connected to the audio circuit;

[0017] The digital circuit is used to receive external control commands and send control signals to the audio circuit according to the external control commands;

[0018] The audio circuit is used to process audio signals according to control signals.

[0019] The digital circuit is specifically described in reference. Figure 2 The digital circuit includes an external control command input port, a control command conversion chip, and an ARM chip connected in sequence; the external control command input port is used to receive external control commands; the control command conversion chip is used to convert the external control commands into signals that the ARM chip can recognize; and the ARM chip is used to send control signals to the audio circuit.

[0020] The audio circuit is specifically described in reference. Figure 3The audio circuit includes a mechanical audio signal input port, which is connected to the input terminal of a first relay. The first output terminal of the first relay is connected to the input terminal of a second relay, and the output terminal of the second relay is connected to the mechanical audio signal output port. The second output terminal of the first relay is connected to the input terminal of a third relay. The audio circuit also includes a line audio signal input port, which is connected to the input terminal of a fourth relay. The first output terminal of the fourth relay is connected to the input terminal of a fifth relay, and the output terminal of the fifth relay is connected to the line audio signal output port. The second output terminal of the fourth relay is connected to the input terminal of the third relay.

[0021] The audio circuit also includes a first amplifier, a digital potentiometer, a second amplifier, a first electronic switch, and a Headset output port, which are connected in sequence to the third relay.

[0022] The audio circuit also includes a MIC input port, a third amplifier, a voice compression circuit, a fourth amplifier, a second electronic switch, and a test equipment audio output port connected in sequence.

[0023] The audio circuit also includes a test device audio input port, which is connected to a second electronic switch.

[0024] The audio circuit also includes a PTT forwarding input port and a PTT forwarding output port, which are used to receive and forward forwarding hard commands sent by the test host.

[0025] Furthermore, the ARM chip in the digital circuit is connected to the first relay, second relay, third relay, fourth relay, fifth relay, first electronic switch, second electronic switch, and digital potentiometer in the audio circuit, respectively.

[0026] When testing communication equipment, first connect the communication equipment, the test host, and the test instruments to the corresponding ports of the fully automatic test adapter.

[0027] The control software of the adapter is deployed on the ARM chip in the digital circuit. The ARM chip enables the switching of audio paths, the control of digital potentiometers, and the parsing of communication protocols. Communication with the test host is achieved through a USB interface. The host sends protocol commands to the ARM chip via the USB serial port, and the ARM chip parses the commands and sends corresponding control signals to the audio circuit.

[0028] When testing the reception parameters of communication equipment, the audio signal output by the communication equipment enters the audio circuit through the line audio signal input port or the mechanical audio signal input port according to the test items. The test host sends the corresponding external control commands to the digital circuit according to the test items. The digital circuit then controls the audio circuit to process the audio signal. The processed audio signal then enters the test instrument through the line audio signal output port or the mechanical audio signal output port. The test instrument performs the corresponding parameter tests.

[0029] When testing the reception parameters of communication equipment, if the test item is to measure the maximum audio output parameters of the communication equipment, the audio signal is directly output. The audio signal input from the mechanical audio signal input port is routed from the first relay to the second relay, and then output to the test instrument through the mechanical audio signal output port; the audio signal input from the line audio signal input port is routed from the fourth relay to the fifth relay, and then output to the test instrument through the line audio signal output port.

[0030] When testing the reception parameters of communication equipment, if the test requires volume control of the audio output of the communication equipment, the audio signal input from the mechanical audio signal input port is routed from the first relay to the third relay, then sequentially through the first amplifier, digital potentiometer, and second amplifier to adjust the audio signal level. The adjusted audio signal is then sent to the second relay via the first electronic switch, and finally output to the test instrument via the mechanical audio signal output port. Similarly, the audio signal input from the line audio signal input port is routed from the fourth relay to the third relay, then sequentially through the first amplifier, digital potentiometer, and second amplifier to adjust the audio signal level. The adjusted audio signal is then sent to the fifth relay via the first electronic switch, and finally output to the test instrument via the line audio signal output port. The digital circuit controls the resistance value of the digital potentiometer according to the external control commands sent by the test host, thereby adjusting the audio signal level.

[0031] When testing the receiving function of a communication device, the audio signal output by the communication device enters the audio circuit through the line audio signal input port or the machine audio signal input port. The test host sends the corresponding external control commands to the digital circuit according to the test items. The digital circuit then controls the audio circuit to process the audio signal. The processed audio signal then enters the test host through the Headset output port, and the test host records the audio.

[0032] When testing the receiving function of the communication equipment, the digital circuit controls the audio circuit to process the audio signal. The audio signal input from the machine audio signal input port passes through the first relay, the third relay, the first amplifier, the digital potentiometer, the second amplifier, the first electronic switch, the second relay, and the Headset output port in sequence to enter the test host; the audio signal input from the line audio signal input port passes through the fourth relay, the third relay, the first amplifier, the digital potentiometer, the second amplifier, the first electronic switch, the fifth relay, and the Headset output port in sequence to enter the test host.

[0033] When testing the transmission parameters of communication equipment, the audio signal sent by the testing instrument enters the communication equipment sequentially through the audio input interface of the testing equipment, the second electronic switch, and the audio output interface of the testing equipment. The communication equipment then forwards the signal to another communication device, which in turn sends the received audio signal back to the testing instrument through the audio circuit of another device.

[0034] When testing the transmission function of the communication equipment, the voice signal sent by the test host enters the communication equipment in sequence through the MIC input port, the third amplifier, the voice compression circuit, the fourth amplifier, the second electronic switch, and the audio output port of the test equipment. The communication equipment then forwards the signal to another communication equipment, which in turn sends the received audio signal to the test instrument through the audio circuit of another device.

[0035] This transforms the testing of communication equipment from a semi-automatic to a fully automatic mode, completely freeing up testers, improving testing efficiency, eliminating errors in performance test indicators caused by human intervention, and improving the accuracy of test results; it also allows for human review of test results and storage and retrieval of received voice recordings.

[0036] Although the present invention has been described in detail in this specification with general description and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention are within the scope of protection claimed by the present invention.
