Utility model content
The purpose of this utility model is to provide a kind of function-stable, circuit structure simple Multi-functional safety electricity-using protection system, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of Multi-functional safety electricity-using protection system, comprises single-chip microcomputer U1, detection module and voice alarm module, and described single-chip microcomputer U1 is connection detection module, voice alarm module, reseting module, control module and warning lamp module respectively.
As further program of the utility model: described voice alarm module adopts chip U2, and the model of chip U2 is ISD2560.
As further program of the utility model: described single-chip microcomputer U1 model is AT89C51.
As the utility model further scheme: described detection module adopts the model of amplifier U3, amplifier U3 to be LM324.
Compared with prior art; the beneficial effects of the utility model are: the utility model Multi-functional safety electricity-using protection system is by using single-chip microcomputer U1; various defencive function is rolled into one; and can the various fault of intelligent decision; provide voice message, maintain easily maintainer and investigate fault, circuit structure is simple simultaneously; function-stable is various, is applicable to very much promoting the use of.
Accompanying drawing explanation
Fig. 1 is the circuit structure block diagram of Multi-functional safety electricity-using protection system;
Fig. 2 is the circuit theory diagrams of Multi-functional safety electricity-using protection system.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2; in the utility model embodiment; a kind of Multi-functional safety electricity-using protection system, comprises single-chip microcomputer U1, detection module and voice alarm module, and single-chip microcomputer U1 is connection detection module, voice alarm module, reseting module, control module and warning lamp module respectively.
Voice alarm module adopts chip U2, and the model of chip U2 is ISD2560.
Single-chip microcomputer U1 model is AT89C51.
Detection module adopts the model of amplifier U3, amplifier U3 to be LM324.
Operation principle of the present utility model is: detection module data acquisition is carried out to supply line and by obtain signal through amplify, send into single-chip microcomputer U1 and carry out data processing, if find, overvoltage, under-voltage, short circuit etc. are abnormal, then carry out voice message and warning by voice alarm module and cut off power supply circuits.
Refer to Fig. 1,2, supply line voltage signal Vi amplifies in rear transmission single-chip microcomputer U1 by the amplifier U3 of detection module, through single-chip microcomputer U1 computing, failure judgement type (overvoltage, under-voltage, short circuit etc.), exports all kinds of default audio alert information by voice alarm module, and by control module control relay K conducting, open the normally-closed contact that it is positioned at supply line, cut off load electricity consumption, meanwhile, the flicker of warning lamp module is warned.
