Abstract
The invention discloses a prepayment electricity meter balance lower-limit alarm system. The alarm system comprises an AC-to-DC power supply, an alarm light detection module, an alarm sound detection module, a GPRS module, a setting port and a core MCU. The AC-to-DC power supply, the alarm light detection module, the alarm sound detection module and the GPRS module are electrically connected with the core MCU, the setting port is arranged in the core MCU and used for configuration of different detection parameters according to an electricity meter and a negative control terminal, pulse signals generated when an alarm is given out are sent through the prepayment electricity meter and the negative control terminal and introduced into the core MCU, audible and visual alarms are sent through the alarm sound detection module and the alarm light detection module, and short messages are sent to a user through the GPRS module at the same time. Alarm information passing through on-site terminal equipment is automatically converted into mobile phone short message early warning information, a person in charge of the electricity of the customer can learn balance early warning information of electric charge, capacitance exceeding of a transformer and other abnormal electricity utilization information at the first time and takes countermeasures in time, and losses of the customer are avoided.
Description
Technical field
The present invention relates to pre-paying kilowatt-hour meter remaining sum lower limit warning system.
Background technology
A large amount of high pressure users has enabled pre-paying kilowatt-hour meter at present, the electricity charge are supplemented with money in advance and in electricity charge card, are carried out in real time electricity charge deduction, the electricity charge are when Sorry, your ticket has not enough value, ammeter can be sent out audible alarm and the output of early warning metrical pulse, once expense button is complete, take connection to jump the mode of lead-in circuit breaker, cause user to have a power failure, can cause to a certain extent user's loss.Marketing system requires special change user more than 50kVA all should install power information acquisition system (load management terminal) according to province company, in the power information while of real-time supervisory user, for super appearance, wait multiplexing electric abnormality situation device to send audible and visual alarm, marketing main website end, in the situation that alarm does not respond, takes manual remote control tripping operation mode to control its electricity consumption.
Because actual high-voltage customer substation strength on duty is limited, major part is all unattended, daily tour work is to be also difficult to conscientiously handle properly, only depend on the requirement of audible alarm " sending to power off notifying book in advance for 7 days " in being probably difficult to fulfill one's commitments, cannot make electricity consumption client's responsible official to know that the remaining sum early warning information of the electricity charge and transformer surpass the multiplexing electric abnormality information such as appearance in the very first time, cannot take in time counter-measure, cause client's loss.
Summary of the invention
For addressing the above problem, the invention provides a kind of pre-paying kilowatt-hour meter remaining sum lower limit warning system.
The technical solution used in the present invention is:
Pre-paying kilowatt-hour meter remaining sum lower limit warning system, this warning system comprises AC power DC power, warning light detects, chimes of doom detects, GPRS module, mouth and core micro-control unit MCU are set, described AC power DC power, warning light detects, chimes of doom detects, GPRS module is all electrically connected to core micro-control unit MCU, the described mouth that arranges is arranged on core micro-control unit MCU, described setting mouthful for according to ammeter, negative control terminal configures different detected parameters, utilize prepayment meter, pulse signal when negative control terminal sends alarm is introduced core micro-control unit MCU, by chimes of doom, detect, warning light detects and sends audible and visual alarm, by GPRS module, to user, send note simultaneously.
Pre-paying kilowatt-hour meter remaining sum lower limit warning system, this warning system comprises AC power DC power, with ammeter interface circuit, GPRS module, mouth and core micro-control unit MCU are set, described AC power DC power, with ammeter interface circuit, GPRS module is all electrically connected to core micro-control unit MCU, the described mouth that arranges is arranged on core micro-control unit MCU, described setting mouthful for according to ammeter, negative control terminal configures different detected parameters, utilize prepayment meter, pulse signal when negative control terminal sends alarm is introduced core micro-control unit MCU, by GPRS module, to user, send note simultaneously.
Beneficial effect of the present invention: the warning information by on-site terminal equipment is converted into SMS early warning information automatically, make electricity consumption client's responsible official know that the remaining sum early warning information of the electricity charge and transformer surpass the multiplexing electric abnormality information such as appearance in the very first time, take in time counter-measure, avoid client's loss.
Accompanying drawing explanation
Fig. 1 is that the present invention separates independently ultimate principle figure with prepayment meter, negative control terminal.
Fig. 2 is that the present invention is at prepayment meter, the built-in ultimate principle figure of negative control terminal.
1, AC power DC power, 2, warning light detects, 3, chimes of doom detects, 4, GPRS module, 5, mouth is set, 6, core micro-control unit MCU, 7, with ammeter interface circuit.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only, for explaining the present invention, does not form the restriction to protection scope of the present invention.
Shown in Fig. 1, pre-paying kilowatt-hour meter remaining sum lower limit warning system of the present invention, this warning system comprises AC power DC power 1, warning light detects 2, chimes of doom detects 3, GPRS module 4, mouth 5 and core micro-control unit MCU6 are set, AC power DC power 1, warning light detects 2, chimes of doom detects 3, GPRS module 4 is all electrically connected to core micro-control unit MCU6, mouth 5 is set to be arranged on core micro-control unit MCU6, arrange mouthfuls 5 for according to ammeter, negative control terminal configures different detected parameters, utilize prepayment meter, pulse signal when negative control terminal sends alarm is introduced core micro-control unit MCU6, by chimes of doom, detect 3, warning light detects 2 and sends audible and visual alarm, by GPRS module 4, to user, send note simultaneously.
Shown in Fig. 2, this warning system comprises AC power DC power 1, with ammeter interface circuit 7, GPRS module 4, mouth 5 and core micro-control unit MCU6 are set, AC power DC power 1, with the output of ammeter interface circuit 7(metrical pulse), GPRS module 4 is all electrically connected to core micro-control unit MCU6, mouth 5 is set to be arranged on core micro-control unit MCU6, arrange mouthfuls 5 for according to ammeter, negative control terminal configures different detected parameters, utilize prepayment meter, pulse signal when negative control terminal sends alarm is introduced core micro-control unit MCU6, by GPRS module 4, to user, send note simultaneously.
Warning information by on-site terminal equipment is converted into the problem that SMS early warning information scheme comes emphasis solution prior art to exist automatically, it is by prepaid and default minimum alarm power consumption comes and GMS SMS notification system is informed power consumer, avoid by people, not known because of low electric weight early warning, prepayment electric expense exhausts and is de-energized, reduce to affect user power utilization risk, advance pre-paying kilowatt-hour meter erection schedule.Make electricity consumption client's responsible official in the very first time, know the remaining sum early warning information of the electricity charge, take in time counter-measure, avoid client's loss.
