Description
Technical field
The invention relates to intelligent controlling device low pressure low-power user being carried out to remote meter reading and remote pre-payment.
Background technology
Two kinds of situations are had at present for the management of low pressure low-power user power utilization and control device.
One is manual metering and manual site's control device, this device be monthly by meter reading personnel to on-the-spot artificial copy reading ammeter registration, then calculate according to this registration the electricity charge that user occurs last month.When owing electricity charges occurs user, or arrearage advice note need be issued notify that user pays dues in time by meter reading personnel's Advise By Wire, if user still can not pay dues on time, manually need to be had a power failure to on-the-spot by meter reading personnel.After user has paid the electricity charge, meter reading personnel has also been needed to arrive on-the-spot artificial power transmission.This kind of situation that mode workflow is loaded down with trivial details, waste of manpower resource, inefficiency also easily cause electricity arrears.This device critical piece used has casing, electric energy meter, on-load switch.
Another kind of mode is manual metering, IC-card mode pre-payment automatic control equipment.This device arrives first the Power supply business Room in advance by user and pays tariff in advance, and electricity forward purchasing is charged in IC-card, and the scene that then holds is charged to electricity forward purchasing in control device.Along with the increase of user power utilization, the electricity of forward purchasing and reducing gradually.When remaining electricity is few, user can hold Power supply business Room electricity forward purchasing in advance again, and is charged in time in control device.If user does not go power purchase in time or do not supplement with money in time, when remaining electricity is finished, control device will send trip command and trip.Electric company still monthly arrives on-the-spot copy reading ammeter registration by meter reading personnel to the actual clearing of this demand charge.This device critical piece used has casing, electric energy meter, contactor, the controller with IC-card card reader, on-load switch.
The weak point of this kind of mode:
1 still needs meter reading personnel monthly to check meter to scene.
2, user needs to hold business hall electricity forward purchasing, and card is easily lost.
3, card reader is easily damaged, cause not Card Reader, fail to see card and can not supplement with money.
4, to user power utilization situation can not time real monitoring.
Summary of the invention
Because prior art can not fundamentally solve manual metering problem, effectively can not carry out pre-payment, can not to monitoring real during user power utilization situation, automaticity is not high, system equipment reliability, poor stability, the problems such as anti-stealing electricity function difference exist, therefore need to upgrade to prior art condition, thorough solution manual metering, really realizes pre-payment, effectively stops electricity arrears, improve automatization level, electricity theft prevention behavior occurs, and improves system equipment reliability and stability, the invention provides a kind of low voltage long distance intelligent residential district motive power prepayment.
The present invention will take with intelligent miniature controller as core, with CJ20S type A.C. contactor for control device, take signal lamp as information transmission, occur with TM-K1 type Intelligent meter box control device management electricity filching behavior, many technology, many means, comprehensive intelligent controlling device.
Microcontroller is the intelligent terminal control appliance with GPRS communication function, and it has real-time meter-reading function, pre paid functionality, programmable function, real-time monitoring and control far away, urges expense alarm function.
CJ20S type A.C. contactor is the A.C. contactor with electric locking function, and it has tripping operation, close a floodgate two control coils.When pull-in winding is energized, iron core adhesive snap close, main circuit is closed to put into operation, coil instantaneous relase; When disconnecting main circuit, connect snap close control device, contactor discharges, and main circuit disconnects.In the course of the work, contactor control loop does not consume electric energy, therefore claims full energy-saving pressureless type A.C. contactor.This equipment plays the effect disconnected with closed main circuit in the present invention.
Control button plays the effect of closed main circuit in the present invention, and it and controller act on closing coil and the breaking coil of A.C. contactor respectively, thus realizes the closed of main circuit and disconnect.
Signal lamp plays information transfering action in the present invention, and it is divided into run indicator, tripping operation indicator light, alarm lamp, permission combined floodgate indicator light.When run indicator is bright, main circuit normal operation is described.When run indicator is extinguished, illustrate that main circuit has disconnected or line outage; When alarm lamp is lighted, illustrate that the remaining electricity of user reaches alarm threshold, notify that user goes to business hall to pay tariff in advance as early as possible.When the remaining electricity of user is greater than alarm threshold, this indicator light is OFF state; When the indicator light that trips is lighted, illustrate that the remaining electricity of user is finished, contactor trips, and main circuit disconnects.When contactor is closed, main circuit runs, this indicator light is OFF state; When allowing combined floodgate indicator light to light, illustrate that now user can be closed a floodgate by control button.If when this lamp is not lit, presses control button and also cannot close a floodgate.
TM-K1 type control device is assemblied in shunt opening or exerts pressure in the batch meter of coil circuit breaker.When illegal unlatching metering chamber door, control device live line work, several seconds inner breaker tripping operation, and cannot recover voluntarily, could power transmission be recovered after needing electricity-management personnel to hold electronic key decoding, thus stop the generation that user's private opening metering chamber door carries out electricity filching behavior.
Adopt technique scheme, the present invention has following advantage: when user is bought after electricity by the Power supply business Room, staff can be issued to the electricity that user buys in controller at any time by GPRS network, and does not re-use IC-card and pay dues and supplement with money.When needing copy reading ammeter registration day of monthly checking meter, the person of checking meter can by system main website, utilize GPRS network real-time copy reading ammeter registration, the person of checking meter can be removed to the work of on-the-spot copy reading ammeter.When user's dump energy reaches alarm threshold, controller will send alarm command, makes signal indicating device go out sound and light alarm, notifies that user pays tariff in advance in time.Simultaneity factor main website also can send note to user according to the dump energy of controller report in time, to inform the electricity that user is remaining, can remove the person of checking meter from and issue tariff notification to scene.When user's dump energy is finished, controller will send trip command, will trip and power-off, thus stop the generation of user's owing electricity charges after contactor obtains instruction.When user is because of after electricity is finished power-off, when not having pre-paying, user cannot power transmission voluntarily.After user pays tariff in advance and issues, user can start button and power transmission voluntarily, thus realizes administrative staff and no longer go to scene to stop the function of power transmission.
When illegal unlatching metering chamber door, the close lock of electronics will send cut-offing instruction and self-locking, and user cannot recover voluntarily, could recover power transmission after needing administrative staff to hold electronic key decoding, thus stops the generation that user's private opening metering chamber door carries out electricity filching behavior.
