Abstract
The invention discloses an early warning device for a fault of a rectifier, belonging to the technical field of rectifiers. The early warning device comprises an alternating current detection device, a direct current detection device, a single chip, an input device, a speaker and a storage device, wherein the single chip is connected with the alternating current detection device, the direct current detection device, the input device, the speaker and the storage device respectively; the alternating current detection device is connected in series to an alternating current end of the rectifier; and the direct current detection device is connected in series to a direct current end of the rectifier. The early warning device has the beneficial effect that early warning can be performed when input alternating current of the rectifier is overlarge or output direct current is overlarge.
Description
Technical field
The present invention relates to a kind of fault pre-alarming device, specifically is a kind of rectifier fault pre-alarming device, belongs to the rectifier technical field.
Background technology
Rectifier in the automobile is one of indispensable important component part of automobile electric control system, and rectifier is to convert alternating current to direct current, and the electric current that automobile current generator sends converts some vehicle-mounted electronic product electric energy of direct current supply to through the effect of rectifier; Auto rectifier is along with the increase of service time; The instability of the electrorheological of conversion, electric current might become greatly, like this; Make some vehicle-mounted electronic products be in the excessive state of electric current for a long time; Damage equipment is if the electric current of the ac input end of while rectifier also can influence the operate as normal of rectifier when excessive, present also not to the excessive device that carries out early warning of rectifier current easily.
Summary of the invention
To the problem that above-mentioned prior art exists, the present invention provides a kind of rectifier fault pre-alarming device, can be at the interchange input current of rectifier excessive or average anode current when excessive, carry out early warning.
To achieve these goals; The technical scheme that the present invention adopts is: a kind of rectifier fault pre-alarming device; Comprise AC current detection device, direct current detection device, single-chip microcomputer, input media, loudspeaker and memory storage; Single-chip microcomputer is connected with memory storage with AC current detection device, direct current detection device, input media, loudspeaker respectively, and AC current detection device is connected on the interchange end of rectifier, and the direct current detection device is connected on the dc terminal of rectifier.
Further, AC current detection device is an alternating current ammeter.
Further, direct current detection device is a DC ammeter.
Principle of work: interchange input current value and the average anode current value that will set through input media store in the memory storage through single-chip microcomputer; AC current detection device detects the interchange input current value and passes to single-chip microcomputer; The data that single-chip microcomputer calls in the memory storage are carried out analyzing and processing; If the alternating current flow valuve that detects is greater than the alternating current flow valuve of setting; Then the Single-chip Controlling loudspeaker sends early warning, and the direct current detection device detects the average anode current value and passes to single-chip microcomputer, and the data that single-chip microcomputer calls in the memory storage are carried out analyzing and processing; If the DC current values that detects is greater than the DC current values of setting, then the Single-chip Controlling loudspeaker sends early warning.
Compared with prior art; The present invention can be with the interchange input current value and real-time the detecting of average anode current value of rectifier; When the average anode current value surpassed setting value, the present invention can send early warning, thereby the staff is keeped in repair rectifier timely; Avoided other vehicle electronic devices because of being in the excessive damage that causes of electric current for a long time; When the interchange input current value was excessive, the present invention also can send early warning, makes the staff can check in time whether automobile electric control system problem takes place.
