[0002] With the high -speed development of intelligentization of present car industry, the electric circuit on the car wiring harness is more and more and increasingly complex, and the current car wiring harness is in sample line period without electric measuring equipment, so the staff needs to manually turn on detection to each terminal on the car wiring harness. In practice, the above-mentioned manual turn-on detection needs to configure three people at one time, one of which counts, and the other two are responsible for inserting the terminals of the two ends of the loop according to the counting and synchronously according to the counting, and the terminals are respectively inserted into the AB terminal of the plug-in seat, and the turn-on test is carried out. When the circuit is turned on, the single-chip microcomputer controls the corresponding indicating signal lamp to light, and thus the detection result is obtained and recorded. The problem of this processing mode is that it needs to consume a lot of human resources. Therefore, how to develop a new wiring terminal detection auxiliary equipment to overcome the above-mentioned problems in the prior art is the direction that the technical personnel in the field need to study.

[0005] A detection board is provided with a first terminal and a second terminal; the first terminal is used for inserting the terminal of one end of the car wiring harness, and the second terminal is used for inserting the terminal of the other end of the car wiring harness;

[0006] A single-chip microcomputer is signal connected with the first terminal and the second terminal respectively;

[0007] A first indicating lamp is electrically connected with the single-chip microcomputer;

[0008] A second indicating lamp is connected in parallel with the first indicating lamp and is opened / extinguished synchronously with the first indicating lamp;

[0010] A delay light control switch is connected with the player and is used for controlling the player to realize delay power-off; the delay light control switch comprises a photoresistor RG arranged close to the second indicating lamp.

[0011] By adopting the technical scheme, the preset voice file is stored in the player. The time delay light control switch controls the player to play a fixed time (the interval is controlled to be just enough to play one instruction), that is, to enter the time delay power-off state. At this time, the staff respectively inserts one end of the terminal of the automobile wire harness into the first connecting head according to the current instruction, and inserts the other end of the terminal of the automobile wire harness into the second connecting head; thus, the single-chip microcomputer detects the terminal of the wire harness inserted on the detection plate, and when the two terminals are conducted, the first indicator light is controlled to be lit. The staff pulls out the terminal of the wire harness from the connecting head. At this time, the second indicator light is lit synchronously due to being connected in parallel with the first indicator light, the light of the second indicator light controls the time delay light control switch to be conducted, the player is powered on, and the next instruction is played... The above process is repeatedly executed until the preset voice file is played, and the detection of all the terminals of the wire harness is completed.

[0012] Preferably, further comprising:

[0013] The cabinet body, the detection plate, the first indicator light and the player are fixedly installed on the surface of the cabinet body.

[0014] The single-chip microcomputer, the time delay light control switch and the second indicator light are arranged in the cabinet body.

[0015] By adopting the technical scheme, the single-chip microcomputer and the time delay light control switch are protected by the cabinet body. Meanwhile, the external light is avoided from affecting the working of the time delay light control switch.

[0016] Preferably, the cabinet body is provided with a slope surface, and the detection plate is installed on the slope surface.

[0017] By adopting the technical scheme, the ergonomic design makes the inserting process of the staff more smooth.

[0018] Preferably, the cabinet body is provided with a first cavity, and the time delay light control switch and the second indicator light are installed in the first cavity. The single-chip microcomputer is arranged outside the first cavity.

[0019] By adopting the technical scheme, the space for placing the time delay light control switch and the indicator light is reduced, the efficiency of the light triggering is higher, and the configuration requirement of the light intensity of the second indicator light is reduced.

[0020] Preferably, the time-delay light-operated switch comprises a photoresistor RG, a triode V1, a triode V2 and a relay switch K; the collector of the triode V1 is connected with a +6V power supply and one end of the photoresistor RG respectively; the base of the triode V1 is connected with one end of an adjustable resistor RP1 and the other end of the photoresistor RG respectively; the emitter of the triode V1 is connected with one end of a capacitor C1 and one end of a resistor R1 respectively; the other end of the capacitor C1 is connected with the other end of the adjustable resistor RP1 and grounded; the base of the triode V2 is connected with the other end of the resistor R1; the collector of the triode V2 is connected with the positive electrode of a switch diode VD1 and one end of the relay K; the emitter of the triode V2 is grounded; the negative electrode of the switch diode VD1 is connected with the other end of the relay K and the +6V power supply respectively; and the relay K is the power supply switch of the player.

[0021] The working process is as follows:

[0022] When the photoresistor RG is not illuminated, it presents a high resistance, at this time, the triode V1 and the triode V2 are both cut off, and the relay K does not work. When the second indicator lamp is on and illuminates the photoresistor RG, the photoresistor RG presents a low resistance, at this time, the triode V1 is turned on, and the capacitor C1 is rapidly charged. At the same time, the triode V2 is also turned on, and the relay K is attracted, so that the player is powered on and works. When the illumination of the photoresistor RG stops, V1 is cut off, but the stored charge on the capacitor C1 can continue to discharge through R1 to V2, so that V2 is still turned on, and therefore the relay K is still in the attracted state. With the gradual reduction of the charge on the capacitor C1, when it is insufficient to maintain the triode V2 turned on, the triode V2 enters cut-off, and the relay K is released and disconnected, at this time, the player is powered off and stops working.

[0023] Compared with the prior art, the utility model can not need to configure staff to specially execute the operation of reporting number, thereby saving human resources. Meanwhile, the stability of operation is improved, and the error of manual operation is reduced. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0029] The embodiments of the present application will be described in detail with specific examples. Other advantages and effects of the present application can be easily understood by those skilled in the art from the content disclosed in the present specification. The present application can also be implemented or applied in other different embodiments, and the details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present application.

[0030] Embodiment 1, please refer to Figures 1-2

[0031] A counting-on instrument includes a cabinet 100, wherein a slope surface is arranged on the cabinet 100. A detection plate 120 is installed on the slope surface. A first terminal 121 and a second terminal 122 are installed on the detection plate 120. The first terminal is used for plugging a terminal of one end of an automobile wire harness, and the second terminal 122 is used for plugging a terminal of the other end of the automobile wire harness. A player 500 and a first indicator light 310 are further installed on the top of the cabinet 100. The player 500 is used for playing a pre-stored voice file. A first manual key 123 and a second manual key 124 are further installed on the detection plate 120. The first manual key 123 is electrically connected with the player 500 and is used for controlling the player 500 to reset and restart. The second manual key 124 is electrically connected with the player 500 and is used for controlling the player 500 to start up by power-on. (The player 500 adopts a conventional playing device in the prior art, and therefore the power supply related structure is omitted in the present specification. Meanwhile, the reset and restart button and the manual power-on button provided on the player 500 are both conventional mature technologies in the field of playing devices, and the working principle and specific connection will not be described in detail in the present specification.)

[0032] ​The cabinet 100 is provided with a first chamber 131 and a second chamber 132. The single-chip microcomputer 200 is installed in the second chamber 132. The single-chip microcomputer 200 is connected with the first wiring terminal and the second wiring terminal in signal mode, and is connected with the first indicator lamp 310 in electric mode. The single-chip microcomputer 200 is used for detecting the wiring terminal inserted in the detection plate 120, and controls the first indicator lamp 310 to be lightened when the two terminals are detected to be conducted. (This is the general function of the single-chip microcomputer 200 for detecting the wiring, and is not the technical improvement) The second indicator lamp 320 and the delay light control switch 400 are installed in the first chamber 131. The second indicator lamp 320 is connected with the first indicator lamp 310 in parallel mode, and is used for being turned on / off synchronously with the first indicator lamp 310. The second indicator lamp 320 preferably adopts a lamp body which can form a bundle of light rays. In the scheme, the power supply device of each component is a conventional power supply device, and can be selected to be a power supply socket arranged on the cabinet 100 to be supplied with commercial power, or can be detached, and thus is not described in detail herein.

[0033] The delay light control switch 400 is connected with the power supply circuit of the player 500, and is used for realizing delay power-off of the player 500. The delay light control switch 400 is arranged at a position close to the second indicator lamp 320, and is used for triggering the delay light control switch 400 to be started when the second indicator lamp 320 is lightened. In the example, the delay light control switch 400 specifically includes a photoresistor RG, a triode V1, a triode V2 and a relay switch K. The collector of the triode V1 is connected with a +6V power supply and one end of the photoresistor RG. The base of the triode V1 is connected with one end of an adjustable resistor RP1 and the other end of the photoresistor RG. The emitter of the triode V1 is connected with one end of a capacitor C1 and one end of a resistor R1. The other end of the capacitor C1 is connected with the other end of the adjustable resistor RP1 and grounded. The base of the triode V2 is connected with the other end of the resistor R1. The collector of the triode V2 is connected with the positive electrode of a switch diode VD1 and one end of the relay switch K. The emitter of the triode V2 is grounded. The negative electrode of the switch diode VD1 is connected with the other end of the relay switch K and a +6V power supply.

[0034] In practice, the working process is as follows:

[0035] The voice file stored in the player 500 can be configured to include detection plug instructions played in sequence, and a fixed time interval can be configured between two adjacent instructions in the file. The time delay light control switch 400 is configured to control the player 500 to play a fixed time (i.e. only one instruction) every time, that is, to enter the time delay power-off state. At this time, the worker respectively inserts the first wiring head 121 into the terminal of one end of the automobile wire harness and the second wiring head 122 into the terminal of the other end of the automobile wire harness according to the current instruction. Thus, the single-chip microcomputer 200 detects the wire harness terminal inserted into the detection plate 120, and controls the first indicator light 310 to light up when the two terminals are detected to be conductive. The worker records the detection result according to the condition of the first indicator light 310. And no matter whether the wire harness passes the detection, the terminal of the wire harness currently detected is pulled out of the wiring head. If the current terminal pair does not pass the detection, the player 500 is started to continue to play the next instruction by operating the second manual key 124. If the current terminal pair passes the detection, the second indicator light 320 is synchronously lighted up at this time because it is connected in parallel with the first indicator light 310, and the light control time delay light control switch 400 is turned on, so that the player 500 is powered on and continues to play the next instruction... The above process is executed cyclically until the preset voice file is played to the end, that is, the detection of all terminal pairs on a wire harness is completed. Then the first manual key 123 can be operated to detect the terminal pairs on the next wire harness. It should be noted that the detection plate 120, the single-chip microcomputer 200, the first indicator light 310, the first manual key, the second manual key and their connection relationship in the above scheme are all structures of existing mature technology, so they should be regarded as a device with inherent functions, and therefore the present scheme does not involve technical improvement on the function of the software program.

[0036] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the above embodiments. Even if various changes are made to the present application, if the changes fall within the scope of the claims of the present application and equivalent technologies thereof, they still fall within the protection scope of the present application.
