Description

A kind of earth leakage protective device based on PC control

Technical field

The utility model relates to low pressure power consumption control technical field, is specifically related to a kind of earth leakage protective device based on PC control.

Background technology

At present, earth leakage protective is an important resist technology in low pressure electricity protection, is widely used in low voltage electric network as the residual current circuit breaker of one of its carrier, occurs with the accident that prevents leakage fire and loss of life or personal injury.

Traditional intelligent electric leakage controller has one group of unique switching value input defining and one group of unique switching value output defining, and the way of output of switching value output is also unique.Suppose that in product design, switching value input is defined as remote switching function, switching value output is defined as long-range separating brake function, terminal use takes this circuit breaker, and intelligence is used input and the output function of product design initial stage definition, causes the inconvenience for client's use.

Therefore, for avoiding above-mentioned technical problem, necessaryly provide a kind of earth leakage protective device based on PC control, described single chip control module core is AVR.

Utility model content

The purpose of this utility model is to provide a kind of earth leakage protective device based on PC control; taking Single-chip Controlling as core, there is the circuit breaker of the intelligent controller of input and output able to programme, can be according to user required; change input and output definition, finally realizes earth leakage protective Based Intelligent Control.

For achieving the above object; the technical scheme that the utility model is taked is: a kind of earth leakage protective device based on PC control; it comprises: input circuit module, output circuit module, single chip control module, RS232 interface, upper computer control module; described above-mentioned each module and single chip control module have formed the earth leakage protective device based on PC control, and described single chip control module, RS232 interface, upper computer control module have formed host computer-single-chip microcomputer bidirectional communication unit.

Compared with prior art, the utlity model has following beneficial effect: algorithm is easily realized, AVR supports C and assembler language, can utilize C language easily to transplant or collect and approach the advantage of hardware address; Described leakaging controller, can solve input and output function in prior art products design, can not free setting etc. problem; Host computer-single-chip microcomputer, by the two-way communication of RS232 interface, has been realized the variation of Single-chip Controlling function with intelligent.
