Abstract
The utility model discloses a door opening detection alarm system of a watt-meter box, which comprises a main control computer chip; wherein the main control computer chip is connected with an external power supply through a power supply module; meanwhile the main control computer chip is connected with a door opening detection module and a spread spectrum carrier wave module unilaterally through a data line; the spread spectrum carrier wave module is also connected with the external power supply through the power supply module and is connected with a carrier wave sending and receiving module unilaterally. The main control computer chip is connected with a spare battery to enable the system to work as before during power failure. Adopting an integral design, the door opening detection alarm system is less in the wire quantity, simple in structure and small in occupying area and can work normally both when the power is turned and when the power is cut off.
Description
Technical field
The utility model relates to the anti-electricity-theft warning of ammeter box field, is specifically related to a kind of ammeter box detection alarm system of opening the door.
Background technology
Existing ammeter is installed in the metal box the inside usually, and power consumer is checked the power consumption of oneself by ammeter box upper glass window.For preventing that the user from opening ammeter box without authorization, reconfiguration supply line privately, power department has been taked many anti-theft electricity technologies, and modal method is that mechanical door lock cooperates lead sealing to guarantee that ammeter box is not illegally opened, and reaches the purpose that prevents stealing; Perhaps adopt smart card to open the method for ammeter box.But be easy to imitatedly or seal off by force by the people, and lose thief-proof function, and ammeter box is in case by after illegal the unlatching, power department can not in time find, and causes the waste of electric power or usurp.
Summary of the invention
The purpose of this utility model provides a kind of ammeter box detection alarm system of opening the door, and can be in time the on off state of ammeter box be sent on the table case state concentrator of power department.
The ammeter box detection alarm system of opening the door comprises the master control computer chip, and the master control computer chip connects external power source by supply module, and the computer chip of master control simultaneously is by the unidirectional respectively connection of data line open the door detection module, extension frequency carrier module; The extension frequency carrier module also connects external power source by supply module simultaneously, and the unidirectional connection carrier wave of extension frequency carrier module sending/receiving module.The master control computer chip also is connected to a battery simultaneously, as standby electricity, makes native system still work when having a power failure.
When the ammeter chamber door is illegally opened, the detection module that opens the door that is installed on the chamber door will send signal to the master control computer chip immediately, the master control computer chip can send alerting signal immediately, alerting signal is amplified by the extension frequency carrier module, the alerting signal of amplifying is transferred on the table case state concentrator of power department by the carrier wave sending/receiving module again.
The utility model adopts integrated design, and wiring quantity is few, and is simple in structure, and it is little to take up room, and can work when electricity or power failure are arranged.
Description of drawings
Below in conjunction with accompanying drawing the utility model ammeter box detection alarm system of opening the door is described in detail.
Fig. 1 is the open the door block diagram of detection alarm system of ammeter box;
Fig. 2 is the open the door circuit theory diagrams of open the door detection module and master control computer chip of detection alarm system of ammeter box;
Fig. 3 is ammeter box open the door the extension frequency carrier module of detection alarm system and the circuit theory diagrams of carrier wave sending/receiving module;
Fig. 4 is the open the door circuit theory diagrams of supply module of detection alarm system of ammeter box;
Embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the ammeter box detection alarm system of opening the door, comprise the master control computer chip, the master control computer chip connects external power source by supply module, and simultaneously the master control computer chip is by the unidirectional respectively connection of data line open the door detection module, extension frequency carrier module; The extension frequency carrier module also connects external power source by supply module simultaneously, and the unidirectional connection carrier wave of extension frequency carrier module sending/receiving module.The master control computer chip also is connected to a battery E1 simultaneously, as standby electricity, makes native system still work when having a power failure.
The work and the data transmission of other module in master control computer chip institute program stored control the utility model.
Supply module becomes the required direct supply of the utility model with the power source conversion of outside input.
Open the door detection module by door interlock switch disconnection or engage the high-low level signal sent to the master control computer chip.
The alerting signal that extension frequency carrier module and carrier wave sending/receiving module send the master control computer chip is amplified and is sent.
Claims (1)
1, the ammeter box detection alarm system of opening the door, it is characterized in that: comprise the master control computer chip, the master control computer chip connects external power source by supply module, and the computer chip of master control simultaneously is by the unidirectional respectively connection of data line open the door detection module, extension frequency carrier module; The extension frequency carrier module also connects external power source by supply module simultaneously, and the unidirectional connection carrier wave of extension frequency carrier module sending/receiving module; The master control computer chip also is connected to a battery simultaneously.
