Brief description of the drawings

Fig. 1 is circuit theory schematic diagram of the present utility model.

Detailed description of the invention

As shown in Figure 1, the durable actual road test operating parts of automobile described in the utility model number of operations recorder, comprises single-chip microcomputer, and described single-chip microcomputer output interface is connected with display, data storage input interface respectively; The input control interface of single-chip microcomputer is connected with key-press module output interface; First signal input interface at single-chip microcomputer is connected with the first testing circuit; Described the first testing circuit comprises 12-volt dc power supply, described 12-volt dc power supply output two-way, the resistance R 1 of leading up to is connected with diode D1 is anodal, described diode D1 negative pole is connected with first signal input interface and the capacitor C 1 of described single-chip microcomputer, separately lead up to contact switch K1 ground connection, contact switch K1 is for substituting the vehicle-mounted sense switch of detected exemplar, as car door open and close state-detection switch etc.; Secondary signal input interface at single-chip microcomputer is connected with the second testing circuit; The series circuit that described the second testing circuit is made up of contact switch K2 and capacitor C 2 forms, when described contact switch K2 work, be connected with detected vehicular motion parts, as clutch pedal mechanism etc., by the open and close of vehicular motion parts band moving contact switch K2; The stationary contact of contact switch K2 is connected with the secondary signal input interface of described single-chip microcomputer, and the movable contact of contact switch K2 is through described capacitor C 2 ground connection.

When work, in the time that contact switch K1 is closed, the first signal input interface level of single-chip microcomputer becomes 0V from 5V, single-chip microcomputer detects low level, automatically register corresponding first signal input interface is added to 1, and result is deposited in the respective regions of data storage, realize the record of test operation part number of operations.

In the time that contact switch K2 is closed, the secondary signal input interface of single-chip microcomputer becomes low level 0V from high level 5V, single-chip microcomputer detects low level, automatically register corresponding secondary signal input interface is added to 1, and result is deposited in the respective regions of data storage, realize the record of test operation part number of operations.

Single-chip microcomputer controls by key-press module the number of operations that display shows all signal input interfaces or corresponding port, and can realize by key-press module the control functions such as device reset.
