Both the relay control execution mechanism and the prepayment module are connected with the microprocessor; an input end of the metering module is connected with alternating current of 220V; an output end of the metering module is connected with the microprocessor; and the power module is connected with the microprocessor, the metering module, the relay control execution mechanism and the prepayment module. The prepayment electric energy meter further comprises a malignant load identification module; the input end of the malignant load identification module is connected with the alternating current of 220V; and the output end of the malignant load identification module is connected with the microprocessor. The prepayment electric energy meter is capable of identifying illegal electric appliances and switching off the power in time.
Description
Technical field
The utility model relates to the electric energy meter technical field, specifically is a kind of prepayment meter.
Background technology
The prepayment meter of prior art comprises microprocessor, metering module, power module, relay control executing mechanism and pre-payment module, and described relay control executing mechanism, pre-payment module all are connected with microprocessor; The input end of described metering module is connected with the 220V alternating current, and the output terminal of described metering module is connected with microprocessor; Described power module all is connected with microprocessor, metering module, relay control executing mechanism and pre-payment module, for they provide working power.During use, supplement with money through the pre-payment module earlier, after microprocessor is received and supplemented signal with money, through the action of relay control executing mechanism, opening power; When microprocessor calculates when exceeding the number of degrees of supplementing with money through metering module, then through relay control executing mechanism action power dump.There is following defective in the prepayment meter of said structure in the use of reality: well-known; Present student dormitory often can be used many illegal electrical appliances; Like electric furnace, immersion heater, electric mattress, electric heater etc.; The use by force of these electrical equipment can make that the load of electric energy meter is fluctuated, causes electric energy meter to damage, even brings great disaster hidden-trouble to student dormitory.
The utility model content
The technical matters that the utility model will solve is, overcomes the defective of above prior art, and a kind of prepayment meter that can discern illegal electrical appliance and can in time cut off the electricity supply is provided.
The technical scheme of the utility model is; A kind of prepayment meter is provided; Comprise microprocessor, metering module, power module, relay control executing mechanism and pre-payment module, described relay control executing mechanism, pre-payment module all are connected with microprocessor; The input end of described metering module is connected with the 220V alternating current, and the output terminal of described metering module is connected with microprocessor; Described power module all is connected with microprocessor, metering module, relay control executing mechanism and pre-payment module; Described prepayment meter also comprises a pernicious load identification module, and the input end of said pernicious load identification module is connected with the 220V alternating current, and the output terminal of said pernicious load identification module is connected with microprocessor.
After adopting above structure, the utility model compared with prior art has the following advantages:
The utility model prepayment meter also comprises a pernicious load identification module; Can identify the pernicious load in the 220V circuit through this module, and carry signal to give microprocessor, after microprocessor is received signal; Through the action of relay control executing mechanism, cut off the electricity supply.So promptly prevent the use of illegal electrical appliance, thereby guaranteed that electric energy meter normally uses, and reduced the disaster hidden-trouble of student dormitory to a certain extent.
Description of drawings
Accompanying drawing is the structural representation of the utility model prepayment meter.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Shown in accompanying drawing, a kind of prepayment meter of the utility model comprises microprocessor, metering module, power module, relay control executing mechanism and pre-payment module, and described relay control executing mechanism, pre-payment module all are connected with microprocessor; The input end of described metering module is connected with the 220V alternating current, and the output terminal of described metering module is connected with microprocessor; Described power module all is connected with microprocessor, metering module, relay control executing mechanism and pre-payment module; Described prepayment meter also comprises a pernicious load identification module, and the input end of said pernicious load identification module is connected with the 220V alternating current, and the output terminal of said pernicious load identification module is connected with microprocessor.In the present embodiment, pernicious load identification module is by PIC single-chip microcomputer main control module, and voltage, current signal extraction module, alarm output module are formed.Extract signal through voltage, current signal extraction module, give PIC single-chip microcomputer main control module extraction and analysis then, get final product through alarm output module output again.
The utility model prepayment meter also comprises a pernicious load identification module; Can identify the pernicious load in the 220V circuit through this module, and carry signal to give microprocessor, after microprocessor is received signal; Through the action of relay control executing mechanism, cut off the electricity supply.
Below only be described, but can not be interpreted as it is restriction claim with regard to the most preferred embodiment of the utility model.The utility model is not limited only to above embodiment, and its concrete structure allows variation.In every case the various variations of in the protection domain of the utility model independent claims, being done are all in the protection domain at the utility model.
