Abstract
The utility model discloses a fault early warning apparatus for a rectifier, and belongs to the technical field of a rectifier. The fault early warning apparatus comprises an alternating current detection device, a direct current detection device, a single-chip microcomputer, an input device, a loudspeaker and a storage device. The single-chip microcomputer is respectively connected with the alternating current detection device, the direct current detection device, the input device, the loudspeaker and the storage device. The alternating current detection device is in series connection with an alternating current end of the rectifier. The direct current detection device is in series connection with a direct current end of the rectifier. The beneficial effects of the fault early warning apparatus are that early warning is conducted when AC input current or DC output current of the rectifier is excessively high.
Description
Technical field
The utility model relates to a kind of fault pre-alarming device, and specifically 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, rectifier is to convert alternating current to direct current, 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, it is unstable that the electric current of conversion becomes, it is large that electric current might become, like this, so that some vehicle-mounted electronic products are in the excessive state of electric current for a long time, easy damage equipment, if also can affect the normal operation of rectifier when the electric current of the ac input end of rectifier is excessive simultaneously, at present also not to the excessive device that carries out early warning of rectifier current.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model 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 solution adopted in the utility model 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, 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 alternating current ammeter.
Further, direct current detection device is DC ammeter.
Principle of work: interchange input current value and the average anode current value that will set by 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 analysis that single-chip microcomputer calls in the memory storage is processed, 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, the direct current detection device detects the average anode current value and passes to single-chip microcomputer, the data analysis that single-chip microcomputer calls in the memory storage is processed, 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 utility model can be with interchange input current value and real-time the detecting of average anode current value of rectifier, when the average anode current value surpasses setting value, the utility model can send early warning, thereby the staff is keeped in repair timely to rectifier, avoided other vehicle electronic devices because being in for a long time the excessive damage that causes of electric current, when the interchange input current value is excessive, the utility model also can send early warning, makes the staff can check in time whether automobile electric control system problem occurs.
Description of drawings
Fig. 1 is electric theory diagram of the present utility model.
Among the figure: 1, AC current detection device, 2, rectifier, 3, the direct current detection device, 4, input media, 5, single-chip microcomputer, 6, memory storage, 7, loudspeaker.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises AC current detection device 1, direct current detection device 3, single-chip microcomputer 5, input media 4, loudspeaker 7 and memory storage 6, single-chip microcomputer 5 is connected with memory storage with AC current detection device 1, direct current detection device 3, input media 4, loudspeaker 7 respectively and is connected, AC current detection device 1 is connected on the interchange end of rectifier 2, and direct current detection device 3 is connected on the DC terminal of rectifier 2.
AC current detection device 1 is alternating current ammeter; Direct current detection device 3 is DC ammeter.
During use, if when the interchange input current value of rectifier 2 or average anode current value were excessive, the utility model can send alarm, remind the staff in time to carry out the maintenance of rectifier 2 thereby make.
