Abstract
The utility model discloses a test device for testing a combined switch of an automobile steering wheel. The test device comprises a machine body, the machine body is provided with a faucet corresponding to a part to be detected on the switch of the automobile steering wheel, a LCD (Liquid Crystal Display) screen is arranged on the machine body, an analogue-digital conversion module corresponding to each faucet is arranged in the machine body, and a C8051F020 chip used as a display module is also arranged in the machine body. The output end of the analogue-digital conversion module is connected with the input end of the C8051F020 chip, and the output end of the C8051F020 chip is in signal connection with the LCD screen. When the test device is used, as the prior art, in detection, the faucet is connected with the part to be detected on the switch of the automobile steering wheel through a connector, an analogue signal obtained by the connector is converted into a digital signal by the analogue-digital conversion module, and then the digital signal is displayed on the LCD screen under driving of the C8051F020 chip.
Description
Technical field
The utility model relates to a kind of testing apparatus of testing automobile bearing circle combined switch.
Background technology
The testing apparatus of existing testing automobile bearing circle combined switch generally comprises body; Body be provided with the vehicle steering combined switch on need to detect the corresponding socket in position; On socket and vehicle steering combined switch, needing to detect the position in the time of detection is connected through connector; Become with reometer, voltage then and measure, detection reading efficient is low and be prone to cause detection tired.
Summary of the invention
In order to overcome the above-mentioned deficiency of the testing apparatus that has testing automobile bearing circle combined switch now, the utility model provides a kind of testing apparatus that reading efficient is high, be difficult for causing the testing automobile bearing circle combined switch that detects fatigue that detects.
The technical scheme that the utility model solves its technical matters is: a kind of testing apparatus of testing automobile bearing circle combined switch; Comprise body; Described body be provided with said vehicle steering combined switch on need to detect the corresponding socket in position; Also be provided with LCD display on the described body, also be provided with the analog-to-digital conversion module corresponding in the described body, also be provided with C8051F020 chip in the described body as display module with each socket; The output terminal of said analog-to-digital conversion module is connected with the input end of said C8051F020 chip, and the output terminal of said C8051F020 chip is connected with described LCD display signal.
The utility model in use; The same with prior art; On socket and vehicle steering combined switch, need to detect the position in the time of detection and be connected through connector, the simulating signal that connector is obtained is passed through analog-to-digital conversion module and is converted that the driving through the C8051F020 chip is presented on the LCD display after the digital signal to.
The beneficial effect of the utility model is: directly show detection numerical value through display screen, detect reading efficient height, be difficult for causing detection tired.
