Description
Technical field
The utility model relates to a kind of vehicle testing line, especially a kind of automotive speedometer check-out console of vehicle testing line.
Background technology
Vehicle testing line is the Vehicle Inspection imperative equipment, can be used for the performance of the each side of automobile is detected, and automotive speedometer check-out console wherein is used to detect the device of automotive speedometer exactly.Known, the automotive speedometer check-out console needs control system to control, come the automobile various aspects of performance is tested by the respective detection element, and cooperation sensing element, give the upper main control computer of deal with data with detecting data transmission, finally handle the related data information that obtains automotive performance by exchange, traditional automotive speedometer check-out console control system, generally all be to adopt various circuit board integrated circuit boards, simulating signal is plug-in, in conjunction with the mode of I/O signal Processing, be installed in the computing machine separately, realize functions such as data acquisition and control in real time, make the control system one-piece construction disperse like this, be generally the detection of realization certain a bit, need specially join a computing machine, not only the cost height assembles up comparatively difficulty, causes the connection line complexity, reliability is low, use dumbly, therefore problem such as antijamming capability is weak is necessary to make improvements.
Summary of the invention
The purpose of this utility model is to provide a kind of automotive speedometer check-out console that possesses integrated control system.
The utility model is that the technical scheme that its technical matters of solution is adopted is:
The automotive speedometer check-out console, comprise check-out console stage body and control system, corresponding site is provided with optoelectronic switch on the stage body, solenoid valve, the stage body lifting jack, cylinder, and speed pickup, it is characterized in that described control system is that an integrated speedometer detects control module, this speedometer detects control module and comprises central processing unit, ROM (read-only memory), random access memory and counter, ROM (read-only memory) wherein, random access memory and counter are connected with central processing unit respectively, central processing unit connects the optoelectronic switch of stage body by the input end of I/O port, this central processing unit also is connected with the communication port with the main control computer communication, and the speed pickup of relevant position is connected on counter and the stage body.
The beneficial effects of the utility model are: the integrated form speedometer that the utility model adopted detects control module, make that the The whole control system height is integrated, improved the reliability and stability of system greatly, in use, only need connect on request and just can by circuit, very be convenient to install and debugging, and itself and host computer adopt the serial data communication mode, have saved the computing machine that detects station, have saved cost, in addition, if system breaks down, the user only needs maintenance, change speedometer detection control module and get final product, and do not need the professional of producer to safeguard, greatly facilitate the user, and realized certain non-maintaining function.
Description of drawings
Be described further below in conjunction with the drawings and specific embodiments:
Fig. 1 is a principle calcspar of the present utility model;
Fig. 2 is a workflow diagram of the present utility model.
Embodiment
As shown in Figure 1, the automotive speedometer check-out console comprises check-out console stage body and control system, and corresponding site is provided with on the stage body: whether optoelectronic switch is used to detect automobile and puts in place; Cylinder is used for the wheel of bearing automobile; Solenoid valve, tradition connects the stage body lifting jack, is used for the lifting automobile; Motor provides power to cylinder; Speed pickup is used to detect car speed.
In the utility model, described control system is that an integrated speedometer detects control module, this speedometer detects control module and can be arranged in the housing usually, its inner member comprises central processing unit, ROM (read-only memory), random access memory and counter, ROM (read-only memory) wherein, random access memory and counter are connected with central processing unit respectively, ROM (read-only memory) stores the control system program, central processing unit is as the control core, extracting control program handles, random access memory stores various data in system work process, take for central processing unit, corresponding I/O port and communication port are set on housing, central processing unit is by the corresponding components and parts of I/O port with the connection stage body, realize the control of data acquisition or components and parts, concrete: central processing unit connects the optoelectronic switch of stage body by the input end of I/O port, be used to gather photoelectric switching signal, the speed pickup of relevant position is connected on counter and the stage body, with the conversion of signals that will detect is count signal, offers central processing unit again.In addition, central processing unit also is connected with remote signal receiver by the input end of I/O port, and to increase control mode, in use, the user can select remote control control or manually control.In housing, also will be provided with power circuit in addition, connect external power or self-powered to each components and parts power supply, to keep operate as normal.
As shown in Figure 2, speedometer of the present utility model detects control module and is connected to host computer by communication port, during work, host computer provides order, and central processing unit judges whether order is correct, and judgement command type, whether the optoelectronic switch detection automobile with stage body puts in place afterwards, if put in place, then falls by the solenoid control lifting jack, wheel of the bus is carried on the cylinder, can judge manually this moment or remote control is carried out, and starter motor afterwards is by cylinder driving automobile wheel turns, in rotation process, gather vehicle speed data by vehicle speed sensor, the data of being gathered obtain the information of needs by rolling counters forward, are transferred to central processing unit, to be collected finishing, the power failure machine rises lifting jack again, gives host computer with the data upload that collects at last, finally handle by host computer, with the automobile speed checking information that needing to obtain.
As seen, the utility model adopts the integrated form speedometer to detect control module, make that the The whole control system height is integrated, improved the reliability and stability of system greatly, in use, only need by circuit connect on request just can, very be convenient to install and debugging, and itself and host computer employing serial data communication mode, saved the computing machine that detects station, saved cost, in addition, if system breaks down, the user only needs maintenance, changing speedometer detection control module gets final product, and do not need the professional of producer to safeguard, greatly facilitate the user, and realized certain non-maintaining function.
