Abstract
The utility model relates to a self -detection device of tractor electrical apparatus box, include the LED pilot lamp parallelly connected with the fuse, current -limiting resistor of LED pilot lamp series connection. The utility model discloses a LED pilot lamp is instructed the insurance of fusing, helps the quick fault localization circuit of maintenance person person, and simple structure, and is with low costs, be applicable to the fault indication of ordinary tractor electrical apparatus box.
Description
Technical field
This utility model is related to the accident indicator being connected with protection device, more particularly to a kind of tractor electrical appliance kit
Self-checking unit.
Background technology
Electrical appliance kit is the standard configuration on common tractor, its effect be the relay required for car load, electric fuse and
Other associated appliance elements are assembled into an entirety by printed circuit board (PCB) and shell, are docked with overall wire sheaves by plug connector,
So as to realize the integration control function of electric equipment.Electrical appliance kit possesses that size is little, low cost and other advantages, but due to the electricity of electrical appliance kit
Gas element degree of integration is high, once breaking down, keeps in repair complex, and not possessing the operator of Professional knowledge cannot be carried out to it
Malfunction elimination.The high-end tractor in part is equipped with programmable PLC, and electrical appliance kit can be monitored, so as to realize
The self diagnosis of electrical system, but because cost is too high, it is not suitable for common tractor.
The content of the invention
The purpose of this utility model is to provide a kind of self-checking unit of tractor electrical appliance kit, it is adaptable to commonly draw machine electric appliance
The indicating fault of box.
The purpose of this utility model is realized by following technical proposals：A kind of self-checking unit of tractor electrical appliance kit, bag
Include the LED light in parallel with electric fuse, one current-limiting resistance of the LED light series connection.
Further, one fault diagnosis single-chip microcomputer of the electric fuse parallel connection, the fault diagnosis single-chip microcomputer connects with instrument
Connect.
More specifically, the fault diagnosis single-chip microcomputer is connected with CAN module, and the CAN module is total by CAN
Line is connected with the instrument.
This utility model has the advantage that compared with prior art：
1st, this utility model indicates the insurance for fusing that assistance maintainer quickly positions event by LED light
Barrier circuit, and simple structure, low cost.
2nd, this utility model is supervised in real time using fault diagnosis single-chip microcomputer to the electric current of fuse state, critical circuits
Control, and corresponding failure code is sent to instrument by the working condition of critical circuits and after breaking down, by instrument to driving
The person of sailing more intuitively is reminded, and to maintainer certain maintenance direction is provided.
This utility model is described in detail below in conjunction with the drawings and specific embodiments.
Description of the drawings
Fig. 1 is the structural representation of this utility model preferred embodiment.
Specific embodiment
Embodiment one：
Referring to Fig. 1, the self-checking unit of tractor electrical appliance kit of the present utility model, indicate including the LED in parallel with electric fuse 1
Lamp 2, one current-limiting resistance 3 of series connection of the LED light 2.
In prior art, tractor electrical appliance kit is mainly made up of following sections：Shell, functional module, shell plays guarantor
The effect of shield and fixed electric elements, the bonnet of shell is integrally formed, and overall wire sheaves can pass through waterproof connector directly and electrical equipment
Box connects；Functional module includes the elements such as electric fuse, relay, PCB, and the electrical system of whole machine can be controlled
System, for realizing the basic function of electrical appliance kit.This utility model is arranged in PCB.
Referring to Fig. 1, in the present embodiment, the left end of electric fuse 1 is connected with power supply, and the right-hand member of electric fuse 1 connects protected unit
Part.Protected element can be steering indicating light, headlight, wiper, each display lamp etc..When electric fuse 1 is normal, LED is indicated
Lamp 2 and current-limiting resistance 3 are shorted, and LED light 2 does not work；After electric fuse 1 fuses, electric current process is had in LED light 2,
LED light 2 is lighted, and represents that the circuit breaks down.Realize that electric fuse indicates function, side under conditions of cost increases seldom
Help the quick locating bad lines of maintainer.
Referring to Fig. 1, in the present embodiment, the fault diagnosis single-chip microcomputer 4 in parallel of the electric fuse 1, the fault diagnosis
Single-chip microcomputer 4 is connected with instrument.Fault diagnosis single-chip microcomputer (MCU), can be to circuit by the voltage-contrast before and after electric fuse switching
State carry out monitor in real time, realize the self-diagnostic function of ordinary appliances box.
Preferably, the fault diagnosis single-chip microcomputer 4 is connected with CAN module, and the CAN module is total by CAN
Line is connected with the instrument.When fault diagnosis single-chip microcomputer detects exception, CAN module can be controlled, by CAN by phase
The failure code answered is sent to instrument, and driver is more intuitively reminded by instrument, provides certain to maintainer
Maintenance direction.In the present embodiment, electrical appliance kit bus protocol meets CAN2.0 standards, and compatible most CAN are total for communication aspects
Line instrument.
This utility model can also be used for the work condition inspection to relay and other related elements.
Content disclosed in embodiment is only this utility model preferably specific embodiment, but protection of the present utility model
Scope is not limited thereto, and any those familiar with the art, can in the technical scope that this utility model is disclosed
The change or replacement for readily occurring in, all should cover within protection domain of the present utility model.
