Anti-electricity-stealing intelligent electronic lock of metering tank

Abstract

The invention discloses an anti-electricity-stealing intelligent electronic lock of a metering tank. An external computer and an electronic key are both connected with an adapter, wherein the computer stores the authorization information of the key and the key ID (identity) number in a storage chip U3 and a clock chip U4 of the electronic key through the adapter; when the electronic key unlocks, a battery of the electronic key supplies power to a single chip U5 of an electronic lock so that the single chip U5 reads information in the storage chip U3 and clock chip U4 and compares the information; finally, the single chip U5 starts a power tube Q2 so that an electromagnet acts and drives a bolt to draw back to open the locked door; and a travel switch acts under the driving of the bolt andstores the unlocking information in the storage chip U3. By adopting the metering tank disclosed by the invention, only when a manager offers the authorization information and ID number of the key, can an unlocking people open the lock within the range of the authorization information; the unlocking record is stored in the key and fed back to the manager; one key can open multiple locks; the anti-electricity-stealing intelligent electronic lock disclosed by the invention has good anti-theft effect and is easy to manage and low in using cost.

Description

technical field [0001] The invention relates to a metering box anti-stealing electronic lock. Background technique [0002] With the continuous extension of the power supply network and the increasing number of power customers, the traditional management of electric energy metering boxes can no longer meet the needs of enterprise development, which has seriously affected the improvement of enterprise economic benefits and the development of service work, mainly in the following aspects : [0003] 1. The mechanical or magnetic keys currently used in the locks of the electric energy metering box have poor anti-copying ability and are easy to crack. When the electric energy metering device is operated illegally, it is easy to have legal disputes with electric power customers. Power supply companies have to frequently replace locks, wasting a lot of manpower and material resources. [0004] 2. The power supply enterprise does not have an effective monitoring method for the op...

AI Technical Summary

Problems solved by technology

[0004] 2. The power supply enterprise does not have an effective monitoring method for the opening and closing of the electric energy metering box, and cannot grasp and control information such as the personnel, time, and frequency of opening and closing the electric energy metering box

[0005] 3. Due to the large number of electric energy metering boxes, the number and specifications of keys are relatively large, and the process of issuing keys takes up a lot of time, and mistakes often occur in key management

[0006] 4. The padlocks of the existing metering boxes are used in separate units to distinguish the lock numbers, which must be customized from the manufacturer, and the cost is relatively high

[0007] 5. The padlock of the traditional metering box has no rainproof device, and it will rust soon after a few months, so that the maintenance personnel of the power supply company have to take active destructive behavior

[0008] 6. At present, domestic research on the monitoring and management of electric energy metering boxes is mostly focused on the opening and closing detection of the box door, and the detection results are transmitted to the main station by TTU or load control device through GPRS or carrier wave. This method solves the problem of the door opening and closing. Closed detection, but it is impossible to know who opened and closed the door, and at the same time, it is impossible to detect the opening and closing of the door when the power is off.

[0009] In short, the mechanical or magnetic keys used in the existing electric energy metering boxes have poor anti-copying ability, easy cracking, poor anti-theft ability, and short service life. Once lost, dozens of sets of locks with the same number need to be replaced, and the use cost is high. The management of the key is cumbersome, with a large amount of management, frequent mistakes, and cumbersome use. It can only monitor the opening and closing of the box door, and it is impossible to know who opened the box door. Due to legal disputes, power supply companies have to frequently replace locks, wasting a lot of manpower and material resources
