Abstract
The utility model provides a kind of electrical system self-diagnosis system, including at least one output element, and output element is provided with driving electrical equipment valve, in addition to for detecting the current sensor of electric current, current sensor is arranged on the total input-wire of electrical system.The utility model detects that the size of circuit operating current is compared with normal current using current sensor, and diagnosis input pull-down or component wear, whole device are simple in construction, is easy to operation；The intellectuality for significantly improving system and the cost for reducing service, also substantially reduce equipment failure rate.
Description
Technical field
The utility model is related to a kind of electrical system self-diagnosis system.
Background technology
Electric automatic control technology is more due to input and output, and difficulty has an effective method to carry out autodiagnosis always
It is disconnected.Particularly with the circuit control of hydraulic pressure or pneumatic element, due to there is multipath electrovalve, detection gets up more complicated, extremely
The present can not realize whether normal to its output end or open/short detection, more can not accurately judge electric or pneumatic
Or the failure of hydraulic system, it can not also detect that electrical system is slept whether body is normal, bring bigger economic loss.
The content of the invention
Goal of the invention of the present utility model is to provide a kind of electrical system self-diagnosis system, mainly solve prior art without
Method diagnoses the problem of whether electrical system is normal automatically.
The technical scheme that the utility model solves the above problems is：The electrical system self-diagnosis system provided, including extremely
A few output element, the output element is provided with driving electrical equipment valve, in addition to for detecting the current sensor of electric current, institute
Current sensor is stated to be arranged on the total input-wire of electrical system.
The electrical system self-diagnosis system also includes shearing device, and the shearing device is arranged at the total input-wire of electrical system
On, when discovery circuit has exception to cut off main circuit at any time, equipment failure rate is substantially reduced.
Advantage of the present utility model：
The utility model detects that the size of circuit operating current is compared with normal current using current sensor, diagnoses
Input pull-down or component wear, whole device are simple in construction, are easy to operation；Significantly improve the intellectuality and reduction of system
The cost of service, also substantially reduces equipment failure rate.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Reference is detailed as follows：
1- current sensors；2- total input-wires；3- output elements；4- drives electrical equipment valve；5- shearing devices.
Embodiment
The utility model is described in detail according to Figure of description：
Electrical system self-diagnosis system as shown in Figure 1, including at least one output element 3 and the electricity for detecting electric current
Flow sensor 1, output element 3 is provided with driving electrical equipment valve 4, and current sensor 1 is arranged on the total input-wire 2 of electrical system.
For the ease of the failure cause of repair apparatus, the device is also equipped with shearing device 5 on total input-wire 2, works as discovery
Circuit has exception to cut off total input-wire 2 at any time, and equipment failure rate is substantially reduced.
Operation principle of the present utility model：
Before the mounting, the driving electrical equipment valve 4 of each output element branch road has a normal current value, by
The electric current for increasing the higher 1 pair of each branch road of current sensor of a precision on total input-wire is acquired.When whole electrical system fortune
After row is opened, current sensor 1 gathers the electric current of each branch road successively, and the current measurement value of each branch road is entered with normal current value
Row compare, if finding, the measured value of the branch road and normal current value are differed, can determine whether the branch road exist open/short or
The problem of appliance controller is damaged, now, should specifically be detected to the branch road, take a location survey measure to avoid bringing serious
Consequence；If it was found that the measured value of each branch road is identical with normal current value, judging that equipment self-diagnosis is normal.
