Description
Technical field
The utility model belongs to Automotive electronic speedometer calibration technology field.Be specifically related to the device of a kind of Automotive electronic speedometer assembly verification.
Background technology
Along with electronic technology is in the fast development of automobile electronics, the production of Automotive electronic speedometer is particularly important.In the process that Automotive electronic speedometer is produced, Automotive electronic speedometer all will carry out assembly verification, and this procedure is the critical process of product.The equipment being generally used for Automotive electronic speedometer verification comprises power supply, industrial computer, LCDs, manipulation keyboard, cable etc.Originally Automotive electronic speedometer verification is the verification undertaken by electronic tachometer tester and external power supply, and equipment is more in disorder.So in process of production because Automotive electronic speedometer voltage signal is easily gone here and there in electronic tachometer tester, make frequent replacing and maintenance electronic tachometer tester, cause ensureing normal production.
Summary of the invention
The purpose of this utility model is exactly the deficiency for general Automotive electronic speedometer tester, provides a kind of Novel intelligent electronic tachometer calibration equipment for Automotive electronic speedometer verification.
Technical solution of the present utility model is: a kind of electronic tachometer calibration equipment, comprises power supply, industrial computer, LCDs, manipulation keyboard, cable, chassis body, it is characterized in that: also comprise the frame of four layers, chassis body and power distribution cabinet; LCDs is loaded on the ground floor of frame, and manipulation keyboard is loaded on the second layer of frame, and chassis body is loaded on the third layer of frame, and power distribution cabinet is loaded on the 4th layer of frame; Controllable electric power, relay card are housed in power distribution cabinet; Chassis body is built with power supply, industrial computer, relay control module and frequency control module, and Control plate is connected with industrial computer end with frequency control card; Manipulation keyboard is connected with industrial computer USB interface.
Also comprise the protection circuit of band duodiode in technical solution of the present utility model, the output terminal of this protection circuit input termination device frequency signal, exports terminable products.
The utility model is owing to being loaded on the ground floor of frame by LCDs, manipulation keyboard is loaded on the second layer of frame, power supply, industrial computer, control module are loaded in chassis body, be loaded on the third layer of frame, controllable electric power and relay board to be installed in panel box in the 4th of frame the layer, thus to form all-in-one-piece Automotive electronic speedometer assembly calibration equipment, compact conformation, floor area is little, easy to operate.The utility model is protection circuit in addition, avoids in production run because Automotive electronic speedometer voltage signal easily goes here and there electronic tachometer checking table frequency signal.
Accompanying drawing explanation
Fig. 1 is structure front schematic view of the present utility model.
Fig. 2 is the circuit diagram of utility model protection circuit.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1.The utility model electronic tachometer calibration equipment is made up of frame 1, chassis body 2, LCDs 3, manipulation keyboard 4, power distribution cabinet 5, wherein contain power supply, industrial computer, relay control module and frequency control module in chassis body 2, containing controllable electric power in power distribution cabinet, relay card.Frame 1 is the frame of four layers, and LCDs 3 is loaded on the ground floor of frame 1; Manipulation keyboard 4 is loaded on the second layer of frame 1, and chassis body 2 is loaded on the third layer of frame 1, and power distribution cabinet 4 is loaded on the 4th layer of frame.
As shown in Figure 2.Protection circuit is conventional duodiode protection circuit.Protection circuit is connected to the output terminal of device frequency signal, adopts duodiode protection circuit to avoid in production run because Automotive electronic speedometer voltage signal easily goes here and there electronic tachometer checking table frequency signal.
The utility model overcomes the deficiency of general Automotive electronic speedometer assembly calibration equipment design, have automaticity high, with the feature of protection circuit, industrial computer control etc., be mainly used in the verification of automotive electronics rotating speed assembly.Manipulation keyboard is connected with industrial computer USB interface, for controlling the Automotive electronic speedometer assembly verification of each gear.Frequency control in the utility model is that industrial computer controls, in addition protection circuit, avoids because Automotive electronic speedometer voltage signal easily goes here and there electronic tachometer checking table frequency signal in production run, this protection circuit employing duodiode D1, D2.
