[0033] Example 1

[0034] This embodiment proposes a multi-channel voice port detection device, such as Figure 1 As shown, it is a connection diagram of the two main modules of the device, including: a multi-channel voice interface module and a voltage range detection module; the multi-channel voice interface module is connected to multiple voltage range detection modules; the voltage range detection module includes a prompter; the multi-channel voice interface module is used to access the voice plug of a large voice gateway, and the voltage range detection module obtains the voice plug voltage received by the multi-channel voice interface module; when the voltage range detection module detects that the voltage meets the preset value, the prompter gives a prompt that the voltage meets the preset value; when the voltage range detection module detects that the voltage does not meet the preset value, the prompter gives a prompt that the voltage does not meet the preset value.

[0036] Example 2

[0037] Based on Example 1, combined Figure 2 and Figure 5 This embodiment describes in detail the electronic component connection method of the multi-channel voice interface module in the utility model.

[0038] In this embodiment, the indicator is a light emitting diode (LED); when the voltage range detection module detects that the voltage meets the preset value, the light emitting diode (LED) is in a lit state; when the voltage range detection module detects that the voltage does not meet the preset value, the light emitting diode (LED) is in an off state.

[0039] In a specific embodiment, the prompter can also be a buzzer. When the voltage range detection module detects that the voltage meets the preset value, the buzzer is in a sounding state; when the voltage range detection module detects that the voltage does not meet the preset value, the buzzer is in a silent state.

[0040] The multi-channel voice interface module supports 32 voice interfaces, and the voice interfaces supported by the multi-channel voice interface module include: RJ11 interface, RJ45 interface, DB37 interface and CHAMP64 interface.

[0041] The multi-channel voice interface module includes a first interface X1, a second interface XS1, a third interface XS2 and a fourth interface XS3; the multi-channel voice interface module is connected to the voice interfaces of different voice gateways through the first interface X1, the second interface XS1, the third interface XS2 and the fourth interface XS3; the first interface X1 is a DB37 interface, the second interface XS1 is an RJ45 interface, the third interface XS2 is a CHAMP64 interface, and the fourth interface XS3 is an RJ11 interface; wherein the first interface X1, the second interface XS1 and the third interface XS2 support receiving 32-channel voice signals, and the fourth interface XS3 supports receiving 4-channel voice signals.

[0042] In a specific embodiment, the schematic diagram of connecting the first interface to the fourth interface to the voltage range detection module is as follows: Figure 2-Figure 5 As shown in the figure, FXSTEXT represents a voltage range detection module, and it can be seen that each adapted interface can be connected to multiple voltage range detection modules. TIP and RING both represent voice signals collected by the multi-channel voice interface module, which are input into the voltage range detection module through the interface pins.

[0043] The voltage range detection module is connected to the multi-channel voice interface module via an RJ11 connection line, and the voice plug voltage collected by the multi-channel voice interface module is used as the power supply voltage of the voltage range detection module.

[0044] In a specific embodiment, Figure 2-Figure 5 As shown, firstly, the chip and pins used in the multi-channel voice interface module of the utility model are explained:

[0045] The first interface X1 is a DB37 interface, which can support 32 voice signals at the same time.

[0046] The first interface X1, the second interface XS1 and the third interface XS2 support RJ45, DB37 and CHAMP64 respectively, while the fourth interface XS3 is RJ11; the above technical features indicate that the multi-channel voice interface module supports 4 different interfaces. In a specific embodiment, the fourth interface XS3 has 4 pairs of signal lines, which can be connected to four identical voltage range detection circuits respectively.

[0047] Example 3

[0048] Based on Example 1 and Example 2, combined Figure 6 , this embodiment describes in detail the specific process of the voltage range detection module performing voltage range detection.

[0049] In a specific embodiment, Figure 6 As shown, the voltage range detection module consists of a rectifier bridge and a switch circuit. It determines whether the voltage is between 48V and 60V by whether the LED light is on, thereby determining whether the signal voltage is within the normal range.

[0050] In this embodiment, the voltage value range that meets the preset conditions is 48V-60V. Figure 6 As shown, the voltage range detection module also includes: a rectifier bridge and a switch circuit.

[0051] The input end of the rectifier bridge is connected to the multi-channel voice interface module, the output end of the rectifier bridge is connected to the switch circuit, and the output end of the switch circuit is electrically connected to the prompter.

[0052] The rectifier bridge includes: a first input end, a second input end, a first diode D1, a second diode D2, a third diode D3, a fourth diode D4, a first interface and a second interface.

[0053] Among them, the first input end and the second input end are both connected to the input end of the rectifier bridge, the first input end is respectively connected to the anode of the first diode D1 and the cathode of the third diode D3, the second input end is respectively connected to the anode of the second diode D2 and the cathode of the fourth diode D4, the cathode of the first diode D1 and the cathode of the second diode D2 are connected to the first interface of the rectifier bridge, and the anode of the third diode D3 and the cathode of the fourth diode D4 are connected to the second interface of the rectifier bridge.

[0054] Preferably, the switch circuit includes: a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a sixth resistor R6, a seventh resistor R7, an eighth resistor R8, a ninth resistor R9, a first transistor Q1, a second transistor Q2 and a third transistor Q3.

[0055] The first interface of the rectifier bridge is respectively connected to one end of the first resistor R1, one end of the second resistor R2 and the collector of the first transistor Q1, the other end of the first resistor R1 is respectively connected to one end of the fourth resistor R4, one end of the fifth resistor R5 and the base of the second transistor Q2, the other end of the fourth resistor R4 and the other end of the fifth resistor R5 are both connected to one end of the third resistor R5, the other end of the second resistor R2 is respectively connected to the base of the first transistor Q1 and the collector of the second transistor Q2, and the emitter of the first transistor Q1 is respectively connected to one end of the eighth resistor R8 and one end of the prompter. In a specific embodiment, as Figure 6 As shown, it is the anode of the light emitting diode LED.

[0056] The second interface of the rectifier bridge is respectively connected to the other end of the third resistor R3, the emitter of the second transistor Q2, one end of the sixth resistor R6 and the emitter of the third transistor Q3, the other end of the sixth resistor R6 is connected to one end of the seventh resistor R7, the other end of the seventh resistor R7 is respectively connected to the other end of the eighth resistor R8 and the base of the third transistor Q3, and the other end of the prompter, in a specific embodiment, as Figure 6 As shown, the cathode of the light emitting diode LED is connected to the collector of the third transistor Q3 through the ninth resistor R9.

[0057] The lowest conduction voltage of the first transistor Q1 is 48V, and the lowest conduction voltage of the second transistor Q2 is 60V.

[0058] It should be noted that when the voltage range detection module is powered on, when the power-on voltage is less than 60V, the second transistor Q2 is not conducting, and the first transistor Q1 is conducting. At this time, when the voltage is greater than 48V and less than 60V, the light-emitting diode LED is in a lit state; when the voltage is greater than 60V, the second transistor Q2 is conducting, the first transistor Q1 is not conducting, and the light-emitting diode LED is in an off state. Therefore, the inspection personnel can detect whether the power-on voltage is between 48V-60V by whether the LED light is on.
