[0003] As shown in Figure 2 In actual use process, internal communication plug 38 has been preset on communication cable 36, so staff only need to wire external communication interface 37.

[0034] The specific use process is as follows:
[0035] When using the signal detection device, the detection communication plug 9 on the detection module 1 is first butted against the external communication interface 37 on the communication interface module 35 to realize the electrical connection of the wiring point one 21 with the first wiring point 3, the wiring point two 22 with the second wiring point 4, the wiring point three 25 with the third wiring point 5, the wiring point four 26 with the fourth wiring point 6, the wiring point five 29 with the fifth wiring point 7, and the wiring point six 30 with the sixth wiring point 8.

[0036] If you want to judge the wiring condition under the RS485 communication mode, press the normally open button SB1 on the first shell 31 to turn on the power supply circuit of the light-emitting diode LED1. If the communication cable 36 is normally connected with the first wiring point 3 and the second wiring point 4 on the external communication interface 37, the light-emitting diode LED1 emits light. If the light-emitting diode LED1 does not emit light, it means that the wiring of the RS485 communication mode is misaligned and needs to be reworked.
[0037] If you want to judge the wiring condition under the TTY communication mode, press the normally open button SB2 on the first shell 31 to turn on the power supply circuit of the light-emitting diode LED2. If the communication cable 36 is normally connected with the third wiring point 5 and the fourth wiring point 6 on the external communication interface 37, the light-emitting diode LED2 emits light. If the light-emitting diode LED2 does not emit light, it means that the wiring of the TTY communication mode is misaligned and needs to be reworked.
[0038] If you want to judge the wiring condition under the CAN communication mode, press the normally open button SB3 on the first shell 31 to turn on the power supply circuit of the light-emitting diode LED3. If the communication cable 36 is normally connected with the fifth wiring point 7 and the sixth wiring point 8 on the external communication interface 37, the light-emitting diode LED3 emits light. If the light-emitting diode LED3 does not emit light, it means that the wiring of the CAN communication mode is misaligned and needs to be reworked.
[0039] If you want to judge the communication mode of the external communication interface 37, press the normally open buttons SB1, SB2 and SB3 in turn. If the corresponding light-emitting diodes are lit, the current communication mode of the external communication interface 37 can be quickly judged. If all the light-emitting diodes are not lit or there are two or more light-emitting diodes lit, it means that the wiring of the external communication interface 37 is wrong and needs to be reworked.
[0040] After using the detection device, the communication interface is separated from the detection communication plug 9, and the internal communication plug 38 is separated from the power supply interface 14.
