The first module 30 is connected to the second module 40. In this embodiment, the first module 30 includes a first group of control switches 31, and the first group of control switches 31 are electrically connected between the first group of signal lines 211 and a plurality of first 8 201028700 resistors R1. The second module 40 includes a second group of control switches 41 electrically connected between the second group of signal lines 221 and the plurality of second resistors R2. The first group of control switches 31 and the second group of control switches 41 may be fast switches or bus bar switches. In the present embodiment, a bus bar switch is used. Each of the first group of control switches 31 and the second group of control switches 41 includes control terminals 31D, 31E, 41D, 41E, first input terminals 31A, 41A, and second input terminals 31C, 41C. And output terminals 31B, 41B. It can be understood that each of the first group of control switches 31 and the second group of control switches 41 can also be composed of two single control terminal switches, each of which has a control terminal and an input. End, one output. By connecting the outputs of the two single control terminals, the above control switch having two control terminals can be made. In this embodiment, when the control terminals 31D, 31E, 41D, and 41E receive the low level signal, the first input terminals 31A, 41A are disconnected from the output terminals 31B, 41B, and the second input terminals 31C, 41C are connected. The connection of the output ports 31B, 41B. When the control terminals 31D, 31E, 41D, 41E receive the high level signal, the connection between the first input terminals 31A, 41A and the output terminals 31B, 41B is turned on, and the second input terminals 31C, 41C and the output terminals 31B, 41B are connection. The control terminals 31D, 31E, 41D, and 41E are connected to the controller 80. The first input terminals 31A and 41A are respectively connected to the first group of signal lines 211 and the second group of signal lines 221, and the second input. The terminals 31C and 41C are respectively connected to the plurality of first resistors R1 and the plurality of second resistors R2, the output terminal 31B is located between the control terminals 31D and 31E, and the output 201028700 terminal 41B is located at the control terminal. Between 41D and 41E, the output terminals 31B and 41B are in communication. During the test, the controller 80 controls the two control terminals 31D, 41D of the first group of control switches 31 and the second group of control switches 41 to open the path between the first input terminal 31A and the output terminal 31B, and disconnects The path between the first input terminal 41A and the output terminal 41B is such that the signals of the first group of signal lines 211 and the second group of signal lines 221 cannot be connected to the first module 30 and the second module 40, so that the test is not affected.

The test circuit is equivalent to the plurality of first resistors ri in FIG. In parallel, the plurality of second resistors R2 are connected in parallel with each other, and the plurality of parallel connected first resistors R1 ❹ are connected in series with the plurality of parallel connected second resistors R2. When the detecting circuit is all turned on, the plurality of first resistors R1 are connected in parallel with each other, and the plurality of second resistors R2 are connected in parallel with each other, and the plurality of parallel connected first resistors R1 and the plurality of parallel resistors are connected in parallel The second resistor R2 is connected in series. A voltage value v will exist in series with the plurality of first resistors R1 and the plurality of second resistors R2. According to v=(R1/n)/(R1/n+R2/n) xVcc', if the contact between the first module 3〇 and the second module 4〇 is poor, the second resistor R2 may not be fully connected to the detection. The circuit, that is, the test circuit cannot be fully turned on. 'There is a formula to see that the second resistor R2 is connected, and the voltage value v will become smaller in 201028700. The detecting module 70 is configured to detect a voltage at a junction of the first module 30 and the second module 40 when forming the detecting circuit. In this embodiment, since the first module 30 is installed in the computer, the detection module 70 is electrically connected to the connection between the first resistor R1 and the first module 30 for the convenience of testing. 70 detects a voltage value V at which the first resistor R1 is connected to the first module 30, that is, a voltage value V at the second input terminal 31C of the first group of control switches 31. The detection module 70 is preset with a threshold value Vt. When the threshold value Vt satisfies the test, when the test circuit is not fully turned on, the detected voltage value V is less than the threshold value Vt, and the detection module 70 outputs a low level. When the test circuit is fully turned on, the detected voltage value V is greater than the threshold value Vt, and the detecting module 70 outputs a high level. In the present embodiment, the threshold value Vt is set in advance. The threshold value Vt is when the test circuit is fully turned on, that is, when the second resistor R2 is all connected, Vt < V, so that the detection mode block 70 outputs a high level when the test circuit is not fully turned on. When the at least one second resistor R2 is not connected, Vt > V, the detecting module 70 outputs a low level. In this embodiment, the controller 80 initially sets the control terminals 31D and 41D of the first group of control switches 31 and the second group of control switches 41 to a low level, and the first group of control switches 31 and The control terminals 31E, 41E of the second group of control switches 41 are set to a high level. In this embodiment, the controller 80 also acquires the signal of the plugging module 10, and when the plugging module 10 detects that the connector 200 is not inserted, the controller 80 does not perform the 11 201028700 test. The connection status of the signal line. When it is detected that the signal from the plug-in module ίο indicates that the connector 200 has been inserted. The controller 80 performs a test of the connection status of the test signal line. The controller 80 first outputs a high level signal only to the two control terminals 31E, 41E, turns on the path between the output terminal 31B and the second input terminal 31C, and the path between the output terminal 41B and the second input terminal 41C. The first resistor R1 and the second resistor R2 are turned on through the output terminals 31B, 41B to form a test circuit. When the controller 80 receives the high level signal of the detecting module 70, it is proved that the signal line is all turned on, and the controller 80 outputs a low level signal to the control terminals 31E, 41E, and disconnects the output terminal 31B. The path between the second input terminal 31C disconnects the path between the output terminal 41B and the second input terminal 41C, and the first resistor R1 and the second resistor R2 are disconnected from the first module 30 and the second module 40, so as to avoid Affects the subsequent transmission of normal signals. The controller 80 outputs a high level signal to the control terminals 31D, 41D, turns on the path between the 10th input terminal 31A and the output terminal 31B, and opens the path between the first input terminal 41A and the output terminal 41B. The output terminals 31B and 41B are turned on, and the signals of the first group of signal lines 211 and the second group of signal lines 221 are connected to the first module 30 and the second module 40, and are turned on through the output terminals 31B and 41B to realize normal communication of signals. . The alarm module 90 is connected to the detecting module 70 for detecting an alarm signal when the detecting module 70 outputs a low level. The alarm module 90 of the present embodiment is configured to determine whether the first group of signal lines 12 201028700 211 and the second group of signal lines 221 are all turned on according to the electrical signals output by the high-low level output rules of the detecting module 70. In the embodiment, the alarm module 9G detects that the detection module is rotated and the computer alarms. If the connection between the module and the module is partially oxidized, the test circuit of the connector detection system cannot be completely k, and the first group signal line is electrically connected to the second group of signal lines. When only the connection between the first module and the second module is fully turned on, the test circuit of the splicer detection system can be fully turned on. At this time, the controller controls the first module and the second module to disconnect the first group of signal lines and The conduction of the second group of signal lines is described. Therefore, the problem of transmission error due to incomplete signal transmission due to poor contact is avoided. In addition, those skilled in the art can make other changes within the spirit of the invention. However, any changes made in accordance with the spirit of the invention are intended to be included within the scope of the invention.
