Abstract
An intelligent electricity theft-proof control device added in an electric energy measurement box applies a microprocessor, which is connected with a key reading circuit, a control circuit for controlling the switching of the main loop of a power supply, a non-volatile memory, a self-reset circuit and an alarming circuit to control the intelligent electricity theft-proof control device. An unpacking detection part is cascaded in the power supply loop of the device, a control contact in a self-locking circuit is controlled by the microprocessor and connected in parallel with the unpacking detection part, and as a result, when the detection part is disconnected, the normal operation of the control device is still ensured. Moreover, a relay controlling the switching of the main loop of the power supply by means of the control contact is provided in the control circuit for controlling the switching of the main loop of the power supply. Not being electricized in the normal situation, the utility model has the advantages of no electricity consumption, safety, reliability, no wrong action and long service life. Meanwhile, because the intelligent control device is controlled by the microprocessor, a user can never illegally open the measurement box, thus radically preventing the occurrence of electricity theft.
Description
Technical field
The utility model relates to a kind of anti-electricity-theft control device, the anti-electricity-theft control device of particularly a kind of electrical energy metering tank additional intelligence.
Background technology
Usually, the stealing electricity method that some areas of China " stealing " person adopts, be to juggle things mostly at electric energy meter or relative metering section, although relevant producer improves its table box structure, but still the generation that can't fundamentally stop stealing electricity phenomenon, this is because " electricity filching person " can be by stealing bitting, even pry open means such as showing case and carry out " stealing ", because management of power use personnel are limited, can not often patrol, prized also to learn it is that who do even found the table case, do not got evidence on the other hand.The utility model patent communique was once announced a kind of name and was called " multi-functional thief-proof electric metering box ", notification number is the patented claim of CN2292289Y, it is characterized in that: the table case is provided with a cipher control electromagnetic lock, be used for the keying of control table case, and, table is provided with a magnetic field sensor that is connected with the control line of electric force of automatic air-break switch in the case, makes the automatic air-break switch tripping operation rapidly when being used for strong magnetic stealing, realizes automatic purpose of cutting off the power supply.Though this batch meter has improved the pick-proof performance to a certain extent, and can effectively avoid the generation of strong magnetic stealing electricity phenomenon, but still can't in time find electricity filching person and other electricity filching behavior is control effectively.Simultaneously, the charged all the time work of The whole control circuit very easily causes misoperation and has power consumption and problem such as serviceable life is short.
The utility model content
The utility model is can't in time find electricity filching person at what exist in the prior art, and its electricity filching behavior control effectively, and because the The whole control circuit caused misoperation of charged all the time work and have power consumption and lack technical matters serviceable life provides a kind of anti-electricity-theft control device of electrical energy metering tank additional intelligence that can effectively overcome above-mentioned shortcoming.
Its concrete solution is: adopt a microprocessor, and make itself and key read circuit, power supply major loop gauge tap control circuit, non-volatile memory to be connected with the self-resetting circuit each several part it is controlled.And the unpacking detection part that is arranged on the chamber door place is serially connected in the electric power loop of this device, make to have only when chamber door is opened and to connect its working power, control contact in the latching circuit of being controlled by microprocessor is in parallel with unpacking detection part, when disconnecting with the assurance detection part, this control device still can operate as normal.And, be provided with relay in the power supply major loop gauge tap control circuit by its control contact control main circuit power break-make.
In addition then, the output control terminal of microprocessor is connected with a warning circuit.
The utility model is not owing to power under the normal condition, so not only not consumed power but also, safe and reliable, no misoperation, long service life, simultaneously, adopt this Intellectualized controller of controlling by microprocessor, stopped fundamentally also that the user illegally opens batch meter without authorization and the generation of the stealing electricity phenomenon that causes thus.

2Constitute, the detection part II that unpacks adopts is one often to start Cheng KaiguanS
4, it and latching circuit relay S
2Normally opened contact S
2-1Be serially connected with after the parallel connection between transformer T secondary and the rectifier bridge DB circuit, make under this device normal condition not power on.And power supply major loop gauge tap control circuit repeat circuit S
1Normally opened contact S
1-1With the gauge tap S among the power supply major loop control VIII
3Serial connection.
During installation, should be with travel switch S
4Be arranged on the chamber door place.Normally under (chamber door is closed) situation, travel switch S
4Disconnect, this intelligence controlling device does not power on, so consumed power does not have the misoperation generation yet.When opening chamber door, travel switch S
4Closure, intelligence controlling device powers on, and microprocessor I starts working, and it at first starts latching circuit, at this moment, relay S
2Work, normally opened contact S
2-1Closure makes travel switch S
4Ineffective, guaranteed travel switch S
4This device still can be kept work during disconnection.Microprocessor I is through time-delay (about 10 seconds adjustable), and PIN reads key information by the key seat, and and memory IC
2In the storage password compare, if read less than or read and memory IC
2The password of middle storage is inequality, and microprocessor I will be to relay S
1Send gating pulse, normally opened contact S
1-1Closure, the gauge tap S in the control of power supply major loop
3The main circuit power supply power supply is cut off in action, and warning circuit is reported to the police.After this microprocessor I does not stop reads key information and to gauge tap S
3Send break pulse, the user can't restore electricity voluntarily, to reach the purpose that prevents from illegally to open the batch meter stealing.In the 6 needle socket PINs of power supply management personnel with supporting key insertion intelligent apparatus, microprocessor I closes audible alarm after reading password and confirming correctly, stops outwards to send gating pulse, discharges latching circuit and makes normally opened contact S
2-1Disconnect the outage of awaiting orders.But manual reversion power supply this moment is closed chamber door after pulling out Electrical key, makes travel switch S
4Disconnect, the device power interruption recovering is to normal condition.
