the analog off-hook and power supply module is used for simulating the off-hook action of the telephone and providing working voltage for the voice repeating module after receiving the telephone ringing signal sent by the tested voice interface;
the voice signal coupling loop is used for coupling the voice signal sent by the tested voice interface to the voice repeating module and coupling the voice signal replayed by the voice repeating module to the tested voice interface;
and the voice repeating module is used for recording the voice signal sent by the tested voice interface and playing back the audio after the recording is completed.
An example of a circuit structure of the above-mentioned detecting device is shown in fig. 4, and the analog off-hook and power supply module includes: the voltage detection chip U1, the rectifier bridge D1, the diode D2, the first resistor R1, the second resistor R2, the third resistor R3, the voltage stabilizing diode VD1, the silicon controlled rectifier SCR1 and the first capacitor C1; the positive electrode output end and the negative electrode output end of the rectifier bridge D1 are connected with a voice signal coupling circuit, the first resistor R1 and the second resistor R2 form a voltage dividing circuit, the voltage dividing circuit is connected between the positive electrode output end and the negative electrode output end of the rectifier bridge D1, and a voltage dividing point is connected with a power pin of the voltage detection chip U1 through a diode D2; the power supply pin of the voltage detection chip U1 is grounded through a first capacitor C1; the control electrode of the silicon controlled rectifier SCR1 is connected with the output pin of the voltage detection chip U1, and the positive electrode of the silicon controlled rectifier SCR1 is connected with the positive electrode output end of the rectifier bridge D1 sequentially through the voltage stabilizing diode VD1 and the third resistor R3; the negative electrode of the silicon controlled rectifier SCR1 is grounded.
The voice signal coupling loop comprises: a second capacitor C2 and a third capacitor C3; one end of the second capacitor C2 is connected with the positive electrode output end of the rectifier bridge D1, and the other end of the second capacitor C is connected with the voice repeating module; one end of the third capacitor C3 is connected with the negative electrode output end of the rectifier bridge D1, and the other end of the third capacitor C is connected with the voice repeating module.
The voice repeating module comprises: the voice recording and playing chip U2, the fourth resistor R4 and the fourth capacitor C4; the power pin of the voice recording and playing chip U2 is connected with a third resistor R3; the recording/playing pin REC/PLAY of the voice recording/playing chip U2 is connected with the power pin of the U2 through a fourth resistor R4 and is connected with the grounding pin GND through a fourth capacitor C4; the positive audio input pin MIC+ and the positive audio output pin SP+ of the voice recording and playing chip U2 are connected with the second capacitor C2; the negative audio input pin MIC-and the negative audio output pin SP of the voice recording and playing chip U2 are connected with the third capacitor C3.
In a specific implementation, the voltage detection chip U1 is a chip capable of detecting that when the voltage reaches a specific voltage threshold, a level jump occurs on an output pin, for example, PT7M7809STEX. The chip has the functions of reaching a voltage threshold and delaying triggering (200 milliseconds can be delayed), and the circuit can be more stable through delaying triggering. The voice recording and playing chip U2 is a chip with recording and playing functions, such as ISD1110, and has the characteristics of interference resistance, high recording and playing tone quality, multiple repeated recording and playing times, power-off voice data protection and the like.
The working principle of the detection device is as follows: the tested voice interface is connected with the detection device through a TIP (positive electrode wire) and a RING (negative electrode wire), and under the normal standby condition, the tested voice interface has a feed voltage of 48V and is powered to the whole device through a rectifier bridge D1. The 48V voltage is divided by the first resistor R1 and the second resistor R2, and as the voltage on the second resistor R2 is less than 3V, the 2 pin of the voltage detection chip U1 outputs low voltage, the silicon controlled rectifier SR1 is in a cut-off state, and the whole detection device does not work.
When the tested voice interface actively sends out telephone ringing, the ringing voltage is superposed with the feed voltage in standby, the voltage is divided by a first resistor R1 and a second resistor R2, the voltage on the second resistor R2 exceeds 3V, the voltage is rectified by a diode D2 and a first capacitor C1 and then is supplied to a voltage detection chip U1, the 2 pin of the voltage detection chip U1 outputs high level, and a silicon controlled rectifier SCR1 is conducted. After the SCR1 is conducted, the whole loop forms loop current, and when the tested voice interface detects that the loop has current, the circuit is considered to be off-hook, and the current tested voice interface stops ringing. Because SCR1 has the characteristic of continuously keeping on after being triggered to be conducted, even if ringing is stopped, SCR1 is still continuously conducted, the whole loop continuously has current, and the feed voltage can be supplied to the voice record-replay chip U2 for use after being stabilized by the voltage stabilizing diode VD 1.
After the tested voice interface detects that the line is off-hook, actively sending out an audio signal; the audio signal is coupled to the voice recording and playing chip U2 through the second capacitor C2 and the third capacitor C3, and the voice recording and playing chip U2 records the audio signal. The 6 pins of the voice recording and playing chip U2 perform recording and playing switching actions, and the level of the 6 pins is switched through a charging delay circuit formed by a fourth resistor R4 and a fourth capacitor C4. After a period of time, the 6 feet are changed from low level to high level, the voice recording and playing chip U2 is switched from a recording state to a playing state, the recording signals are played and coupled to the tested voice interface through the second capacitor C2 and the third capacitor C3, the detecting device compares the voice signals received by the tested voice interface with the voice signals sent out, and if the voice signals are consistent, the tested voice interface passes the test.
