Checkout equipment of motormeter

Abstract

The invention discloses checkout equipment of a motormeter. The checkout equipment is characterized in that the checkout equipment is a communication detection system which is formed in a way that a control main plate is respectively connected with an LIN (local interconnect network) communication module, a CAN (controller area network) bus communication module, a PWM (pulse-width modulation) and frequency module and an A / D conversion module; and the control main plate is connected with a relay module and a resistor module so as to form a signal output control system; and the control main plate is connected with a button collecting module and an LCD (liquid crystal display) display module so as to form a man-machine operation system. As the circuit structure is adopted, the equipment has the advantages that 1, checkout and overhauling of the motormeter are realized with lower cost; 2, the volume is small, and the carrying is convenient; and 3, the operation is convenient when the equipment is used for checking out, and the checkout equipment is easy to master.

Description

[0001] Involved areas [0002] The invention relates to the daily maintenance and detection of automobile meters, in particular to a detection device for automobile meters. Background technique [0003] At present, with the rapid development of automotive electronic technology, the electronic technology of automotive instrumentation is also changing with each passing day, and the detection technology of automotive instrumentation is also becoming more and more advanced. [0004] The detection equipment of most instruments adopts the form of industrial computer, that is, the detection equipment is mainly industrial computer, and the boards that send different signals according to different instrument configurations, such as CAN cards and frequency cards, etc., are very expensive. In addition, it is necessary to design the corresponding upper computer detection software, which prolongs the development cycle of the detection equipment, and the maintenance of the equipment is diff...

[0004] The detection equipment of most instruments adopts the form of industrial computer, that is, the detection equipment is mainly industrial computer, and the boards that send different signals according to different instrument configurations, such as CAN cards and frequency cards, etc., are very expensive. In addition, it is necessary to design the corresponding upper computer detection software, which prolongs the development cycle of the detection equipment, and the maintenance of the equipment is difficult, the movement is inconvenient, and it is not suitable for on-site detection; there is also a type of instrument detection equipment that uses a PC and cooperates with the corresponding signal generator. Such as CAN signal, resistance signal, etc. Most of these signals are independent structures. To detect a set of instruments, various signal generators need to be placed on a table, which is prone to signal interference, and users will be dazzled when the detection time is long. Phenomenon, and need to develop the corresponding host computer software, according to the signal access, need to design special software, increase the cost of equipment development
