Abstract

The utility model discloses an electricity-theft prevention device of an electricity meter box, which comprises a CPU module, a sensor, a motion module, a speaker and a communication module, wherein the sensor is used for sending a signal to the CPU module when monitoring the electricity meter box is opened, and the CPU module judges the signal and then controls the motion module to cut off an air switch, the speaker to tweet, and the communication module to transmit alarm information. The electricity-theft prevention device judges whether illegal people enters or not by a decoding signal prestored in the CPU module, effectively avoids false alarm, automatically cuts off power when judging that electricity theft motion exists, sends the alarm information, carries out alarm by various ways and prevents the electricity theft motion, thus reducing electricity quantity loss.

Description

The anti-electricity-theft device of ammeter box

Technical field

The utility model relates to the ammeter box structure, is meant a kind of ammeter box that can effectively prevent stealing especially.

Background technology

Raising along with socio-economic development and distribution technique, ammeter box is widely used in the electric power supply, be used for accurately measuring power consumption, in order to prevent electricity filching behavior, common on the market ammeter box structure, the unified structure that adopts lead sealing of its shell, but in actual use, lead seal structure is easy to destroyed, treat to lose already after electric power enterprise is found, also can produce a lot of disputes simultaneously, particularly install the place of ammeter concentratedly at some, owing to can't assert divisions of responsibility can, often Ge Ti electricity filching behavior can cause the electricity filching behavior difficulty to be discovered to destroy other validated user lead sealings for following, and not only electric power enterprise incurs loss, individual or enterprise also can be affected, and have upset social electricity consumption order.

For preventing stealing, the a large amount of manpower and materials of electric power enterprise input, diversified anti-electricity-theft device has also appearred in the society, shown in the reference table 1, some is easily destroyed for these anti-electricity-theft devices, do not have the effect that stops electricity filching behavior, in addition, some anti-electricity-theft device adopts the communication technology, in case discovery electricity filching behavior, promptly send alarming short message, yet this device still has the signal conductively-closed or the basement signal is not enough can't to be used because of electric power facility is in to default number, cause anti-electricity-theft device to perform practically no function, moreover it is just to notify electric power enterprise after the actual generation of electricity filching behavior that aforementioned means also has a common shortcoming, has caused the loss that can't retrieve this moment.

Table 1

Product	Advantage	Shortcoming
Product	Advantage	Shortcoming	Theftproof lock	Economical, convenient, easily installation	1) theft-proof is poor, without a few minutes just destroyed, can't find
Common sound alarm	Caution power is strong, easily installs and uses	1) only play warning effect 2) can't stop electricity filching behavior	Theftproof lock	Economical, convenient, easily installation
Common sound alarm	Caution power is strong, easily installs and uses		The GSM Short message alarm	Advanced technology is in time notified the generation of electric power enterprise electricity filching behavior	Stealing produces when 1) reporting to the police, and loss has occurred 2) signal may conductively-closed 3) mostly electric power facility be positioned at the underground distribution chamber, may can't use because of the signal deficiency

Because aforementioned analysis, the design people studies improvement at the defective of present anti-electricity-theft device, and this case produces thus.

The utility model content

Fundamental purpose of the present utility model is to provide a kind of anti-electricity-theft device of ammeter box, and it can effectively avoid false alarm, and stops the transmission of electricity filching behavior, reduces the loss that stealing causes.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of anti-electricity-theft device of ammeter box, comprise CPU module, sensor, action module, loudspeaker and communication module, sensor sends signal to the CPU module when being opened monitoring ammeter box, CPU module control action module after judging disconnects air switch, the control loudspeaker pipe, control communication module transmission warning message.

The sensor is connected with lockset on the ammeter box.

After adopting such scheme, the utility model is monitored by the on off state to ammeter box, simultaneously in conjunction with the decoded signal that prestores in the CPU module, in case ammeter box is opened, but intelligent decision is validated user or disabled user to enter, avoid carrying out false alarm, and can when being judged as the disabled user, realize multiple action:

(1) be suitable for advanced technology such as GSM, can utilize communication module to send note or call to electric power enterprise even assigned number, the very first time reports to the police;

(2) judgement in a single day of CPU module illegally enters, then disconnect air switch, realize outage, stop electricity filching behavior, reduce the loss, this moment, the CPU module air switch that only could close again after receiving from the formal legal authorization of electric power enterprise recovered to send electricity, more was applicable to the place of communication signal conductively-closeds such as basement;

(3) the control loudspeaker send chimes of doom, near the generation of the resident's electricity filching behavior the notice, and personnel cause caution to stealing.

Description of drawings

Fig. 1 is a structured flowchart of the present utility model;

Fig. 2 is an action flow chart of the present utility model.

Embodiment

Below in conjunction with drawings and the specific embodiments the structure of the present utility model and the course of work are elaborated.

With reference to shown in Figure 1, be the structural representation of the anti-electricity-theft device of a kind of ammeter box of the utility model, comprise CPU module 1, sensor 2, action module 3, loudspeaker 4 and communication module 5.

Sensor 2 is used to monitor the on off state of ammeter box, in the present embodiment, can realize by the monitoring to lockset on the ammeter box, and when finding that lockset is opened, sensor 2 sends signal to CPU module 1.

Prestore decoded signal in the CPU module 1, this decoded signal is set by Utilities Electric Co., and CPU module 1 can judge that open ammeter box is legal or the disabled user by this decoded signal; CPU module 1 also is connected with action module 3, loudspeaker 4 and communication module 5, behind the signal that receives sensor 2, and in conjunction with judgement to decoded signal, the action of control action module 3, loudspeaker 4 and communication module 5.

Action module 3 is connected with air switch, under the control of CPU module 1 air switch is disconnected or connection.

With reference to shown in Figure 2, during present embodiment work, when the lockset on the ammeter box is opened, sensor 2 sends signal to CPU module 1, CPU module 1 judges whether to receive decoded signal, and when receiving decoded signal, compare with the data that prestore, if identically then be judged as the personnel of Utilities Electric Co. (being validated user) that hold correct decoded signal, can not report to the police; Be not inconsistent with the data that prestore and work as decoded signal, or when not receiving decoded signal, then be judged as the disabled user, this moment, CPU module 1 was sent instruction to action module 3, and air switch is disconnected, and realized outage, avoid causing electric quantity loss, CPU module 1 is also controlled loudspeaker 4 and is sent warning, and communication module 5 sends alarming short message or calls the notice electric power enterprise to the number of appointment simultaneously.

Above embodiment only is explanation technological thought of the present utility model; can not limit protection domain of the present utility model with this; every according to the technological thought that the utility model proposes, any change of being done on the technical scheme basis all falls within the utility model protection domain.
