Description
Technical field
The invention relates to the intelligence controlling device of low pressure low-power user being carried out remote meter reading and remote pre-payment.
Background technology
For the management of low pressure low-power user power utilization and control device, two kinds of situations are arranged at present.
A kind ofly be manual metering and artificial on-site control device, this device for per month by the meter reading personnel to on-the-spot manually copy reading ammeter registration, the electricity charge that then occur last month according to this registration calculating user.When owing electricity charges occurs in the user, need by meter reading personnel's Advise By Wire or issue the arrearage advice note to notify the user in time to pay dues, if the user still can not pay dues on time, need by the meter reading personnel to on-the-spot artificial the power failure.After the user has paid the electricity charge, also need the meter reading personnel to arrive on-the-spot artificial power transmission.This kind mode workflow is loaded down with trivial details, waste of manpower resource, inefficiency also easily cause the situation of 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 in advance the Power supply business Room by the 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 electric weight of forward purchasing and reducing gradually.When last electric weight is few, user's Power supply business Room electricity forward purchasing that can again hold in advance, and in time be charged in control device.If the user does not in time go power purchase or in time do not supplement with money, when last electric weight was finished, control device will send trip command and trip.Electric company still arrives on-the-spot copy reading ammeter registration by the meter reading personnel per month to the actual clearing of this demand charge.This device critical piece used has casing, electric energy meter, contactor, the controller with the IC-card card reader, on-load switch.
The weak point of this kind mode:
1 still needs the meter reading personnel to check meter to the scene per month.
2, user's business hall electricity forward purchasing that need to hold, and card is easily lost.
3, card reader is easily damaged, and causes not Card Reader, fails to see card and can not supplement with money.
4, to the user power utilization situation can not the time real monitoring.
Summary of the invention
Because prior art can not fundamentally solve the manual metering problem, effectively To Implement Pre is paid, real monitoring in the time of can not be to the user power utilization situation, automaticity is not high, system equipment reliability, poor stability, the problems such as anti-stealing electricity function is poor exist, therefore need to upgrade to the prior art condition, thoroughly solve manual metering, really realize pre-payment, effectively stop electricity arrears, improve automatization level, the electricity theft prevention behavior occurs, and improves the system equipment reliability and stability, the invention provides a kind of low-voltage remote intelligent residential district power prepaid devices.
The present invention will take take the intelligent miniature controller as core, take CJ20S type A.C. contactor as control device, take signal lamp as the information transmission, many technology, many means, comprehensive intelligence controlling device occur with TM-K1 type Intelligent meter box control device management electricity filching behavior.
Microcontroller is the intelligent terminal control appliance with GPRS communication function, and it has real-time meter-reading function, pre paid functionality, long-range control function, real-time monitoring and control, urges the expense alarm function.
CJ20S type A.C. contactor is the A.C. contactor with electric locking function, and it has tripping operation, two control coils close a floodgate.When pull-in winding is switched on, iron core adhesive and snap close, the main circuit closure puts into operation, the coil instantaneous relase; When disconnecting main circuit, connect the snap close control device, contactor discharges, and main circuit disconnects.In the course of the work, the contactor control loop does not consume electric energy, therefore claim full energy-saving pressureless type A.C. contactor.This equipment plays the effect that disconnects 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 respectively closing coil and the breaking coil of A.C. contactor, thereby realizes closure and the disconnection of main circuit.
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, the 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 last electric weight of user has reached alarm threshold, notify the user to go to as early as possible the business hall to pay tariff in advance.During greater than alarm threshold, this indicator light is for extinguishing state when the last electric weight of user; When the tripping operation indicator light is lighted, illustrate that the last electric weight of user is finished, contactor trips, and main circuit disconnects.When contactor closure, main circuit operation, this indicator light is for extinguishing state; When allowing the combined floodgate indicator light to light, illustrate that this moment, the user can close a floodgate by control button.When if this lamp is not lit, presses control button and also can't close a floodgate.
TM-K1 type control device is in the batch meter that is assemblied in shunt opening or the coil circuit breaker of exerting pressure.When illegal unlatching metering chamber door, the charged work of control device, several seconds inner breaker tripping operation, and can't recover voluntarily, need the electricity-management personnel to hold and could recover power transmission after electronic key is decoded, carry out the generation of electricity filching behavior thereby stop user's private opening metering chamber door.
Adopt technique scheme, the present invention has following advantage: after the user bought electric weight by the Power supply business Room, the staff can be issued to the electric weight that the user buys in controller at any time by GPRS network, did not pay dues and supplemented with money and do not re-use IC-card.When day needing copy reading ammeter registration when checking meter per month, the person of checking meter can be by the main website of system, utilize the real-time copy reading ammeter of GPRS network registration, can remove the work that the person of checking meter is arrived on-the-spot copy reading ammeter from.When user's dump energy reached alarm threshold, controller will send alarm command, made signal indicating device go out sound and light alarm, in time notified the user to pay tariff in advance.The simultaneity factor main website also can in time send note to the user according to the dump energy of controller report, with the electric weight of informing that the user is last, can remove the person of checking meter from and issue tariff notification to the scene.When user's dump energy was finished, controller will send trip command, and contactor obtains will tripping and cutting off the power supply after instruction, thus the generation of stopping user's owing electricity charges.After the user was finished outage because of electric weight, in the situation that there is no pre-paying, the user is power transmission voluntarily.After the user paid tariff in advance and issues, the user is start button and power transmission voluntarily, thereby realizes that administrative staff no longer go to the 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 the user can't recover voluntarily, could recover power transmission after needing administrative staff to hold the electronic key decoding, measures chamber door and carries out the generation of electricity filching behavior thereby stop user's private opening.
