Electronic lock with high key secret rate for box

Abstract

An electronic lock with high key secret rate for a box is characterized by comprising a lock body and an electronic key; the lock body consists of a lock shell, a bolt, a driving motor and an intelligent control circuit; the output signal of the intelligent control circuit controls the driving motor which forms a driving relationship with the bolt by a reducer and a rack; the bolt corresponds to a lock hole on a box doorframe and the other end of the bolt is provided with a door-locking spring; the electronic key is internally provided with a lock-opening password memory; and when the password stored by the lock-opening password memory is the same as the password pre-stored by the intelligent control circuit, a microprocessor then orders the driving motor to open the bolt. The invention has simple structure, and easy and fast operation, and leads the electricity-stealer hard to open the box door; and by applying the invention to an electricity meter box, electricity-stealing behavior can be basically prevented, thereby not only reducing economic losses, but also eliminating hidden danger of accidents.

Description

technical field [0001] The invention relates to a high-reliability electronic lock for an electric meter box, belonging to the technical field of locks. Background technique [0002] Electricity is an indispensable source of energy in industrial and agricultural production and people's daily life. In order to reasonably plan electricity consumption and charge electricity fees, the power sector installs watt-hour meters in power supply lines to measure users' electricity consumption. The watt-hour meter is generally installed in the meter box. Driven by economic interests, some people often open the meter box privately and modify the circuit or internal parts of the watt-hour meter to achieve the purpose of stealing electricity. This not only causes economic damage to the power supply company Loss, but also will bring leakage, fire and other accident hazards. [0003] The electric meter box lock is an important device to prevent electricity theft. The existing electric meter...

AI Technical Summary

Problems solved by technology

The watt-hour meter is generally installed in the meter box. Driven by economic interests, some people often open the meter box privately and modify the circuit or internal parts of the watt-hour meter to achieve the purpose of stealing electricity. This not only causes economic damage to the power supply company loss, but also will bring leakage, fire and other accident hazards

[0003] The electric meter box lock is an important device to prevent electricity theft. The existing electric meter box is generally equipped with a mechanical lock. The mechanical lock is easy to be opened by a person who masters the general unlocking technology, and the key is also easy to be copied, so the anti-theft effect is not ideal.

In addition, due to the large number of meter boxes managed by the power department, the number of keys is also large, which is inconvenient to carry, and the keys are similar in shape, so it is difficult to distinguish them. Even if they are marked one by one, it often takes a long time to find individual keys , which brings a lot of inconvenience to the management of the electric box and greatly reduces the work efficiency

If multiple meter boxes use a common key, it can bring convenience to the management personnel, but criminals can open multiple meter boxes as long as they get one key, which greatly reduces the safety of the meter boxes.
