Abstract
The utility model discloses a metering box capable of preventing electricity from being stolen, which is a closed rectangular box body that can be opened. The box body is provided with a visual window, and is internally provided with a knife switch, an electric energy meter and a control system device for monitoring and controlling the normal opening of the box body. The control system device comprises a travel switch, a 5V relay, a 9V relay, a circuit breaker, a single chip microcomputer, an LED (light-emitting diode) indicator light, a buzzer and an electronic key, wherein the single chip microcomputer is connected with the travel switch, the 5V relay, the 9V relay, the LED indicator light and the buzzer respectively; the circuit breaker is connected with the 9V relay; and the electronic key is provided with an electrically erasable programmable read-only memory (EEPROM) chip. After the metering box is adopted, the manufacturing cost is low, and the work is reliable; and after being applied in batch, the metering box is remarkable in effect of preventing electricity from being stolen.
Description
Technical field
The utility model relates to for the electricity distributing and metering device, is specifically related to a kind of electricity-stealing prevention metering tank.
Background technology
In order to realize justice, just electricity consumption, power department will be installed electric energy meter in the electricity consumption client, and often will detect electricity consumer, detects whether have stealing electricity phenomenon.Along with making rapid progress of science and technology, stealing mode and stealing technology are more and more brilliant, and traditional anti-electricity-theft means are difficult to receive ideal effect, and the common electricity filching means of electricity filching person is illegally to open batch meter, then the gauging table meter is illegally adjusted.The mechanical built-in lock of the general employing of traditional batch meter, electricity filching person is easy to open.Prior art can not the complete generation that comprehensively prevents this phenomenon, and therefore, the anti-theft electricity technology measure should develop towards high-tech, robotization, intelligentized direction.
The utility model content
The purpose of this utility model is to solve the problems referred to above of prior art, the novel electricity-stealing prevention metering tank of a kind of with low cost, reliable operation of design.
For addressing the above problem, a kind of electricity-stealing prevention metering tank of the present utility model is an openable closed rectangular box, have visual window on the casing, knife-like switch, electric energy meter are installed in the casing, wherein, the normal control of turning system and device of Monitoring and Controlling casing are installed also in the casing.
Further, described control system device 2 comprises travel switch, 5V relay, 9V relay, isolating switch, single-chip microcomputer, LED light, hummer and electron key, single-chip microcomputer links to each other with hummer with travel switch, 5V relay, 9V relay, LED light respectively, and isolating switch links to each other with the 9V relay.
Further, on the described electron key eeprom chip is housed.
The beneficial effects of the utility model are: the utility model utilizes single-chip microcomputer and electron key, has designed a kind of novel electricity-stealing prevention metering tank.Advantages such as that this device has is with low cost, reliable operation after using in batches, have played tangible power-steeling preventing effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is circuit theory diagrams of the present utility model;
Fig. 2 is the utility model control system device logic block-diagram.
Embodiment
As shown in Figure 1: a kind of electricity-stealing prevention metering tank, be an openable closed rectangular box, have visual window on the casing, knife-like switch, electric energy meter 1 are installed in the casing, wherein, the normal control of turning system and device 2 of Monitoring and Controlling casing also is installed in the casing.
As shown in Figure 2: described control system device 2 comprises travel switch, 5V relay, 9V relay, isolating switch, single-chip microcomputer, LED light, hummer and electron key, single-chip microcomputer links to each other with hummer with travel switch, 5V relay, 9V relay, LED light respectively, and isolating switch links to each other with the 9V relay.Travel switch input signal monitoring open and close door information; The 5V relay provides power supply to control system device 2; 9V relay output control breaker signal; Single-chip microcomputer is implemented logic determines and event handling; LED light is as operation and alarm condition indication; The hummer audible alarm; Electron key is the electron key that eeprom chip is housed, and is used for storing password, simultaneously dynamic password is set when reading eeprom chip at every turn, to prevent being cracked this electron key by the people.
The scm software flow process is as follows: when metering chamber door when being opened, then the travel switch on the batch meter obtains input signal, and pilot relay is given antitheft electric control system device 2 power supplies, and control system device 2 begins to enter and carries out state.At this moment, LED light is lighted, and locks the 5V relay simultaneously, waits for electron key.Then judge password if there is electron key to insert, if password is correct, then control system device 2 is failure to actuate, and LED light keeps flicker at a slow speed.If password bad, LED light fast blink, buzzer call caution, control system device 2 isolating switchs action outage behind the time-delay certain hour.When closing the metering chamber door, judge whether control system device 2 is in legal door opening state, if, then control the outage of 5V relay, closing control system and device 2, flow process finishes.
Principle of work of the present utility model is: when batch meter is opened, if no effective electron key inserts in the Preset Time, anti-electricity-theft control system device 2 control circuit breaker trip outages are also reported to the police, and LED light is bright, buzzer call is reported to the police, and tripping operation outage action is carried out in the back.Insertion up to the effective electron key can restore electricity; If the insertion with the effective electron key in the Preset Time can restore electricity; If insert with the effective electron key in the Preset Time, then anti-electricity-theft control system device 2 is regarded as and is opened the door legally, keeps power supply state.
