The power communication industry, such as power distribution boxes, communication light cross-connect boxes; the transportation industry, such as high-speed rail maintenance doors, bus coin boxes, containers, and the like; in the aspect of public facilities, a monitoring box is one of the more important items; in other fields, such as oil pipe oil conveying ports, bank note conveying boxes, military ammunition storehouses, hazardous chemical storehouses and the like, the safety problem is very important. Locks are widely used in business administration and people's daily life, and businesses and individuals commonly use locks to protect valuable financial and important data. The common lock on the market at present is mainly a mechanical lock, and the lock is unlocked through the cooperation of lock core and key tartar, but this kind of lock core can be opened easily through steel wire or tinfoil, and the security of structure is not high. The mechanical lock has hundreds of years of history along with human life, and even today, the mechanical lock is still the main lock in life, but cannot meet the requirements of modern people on high reliability, high safety, informatization and intellectualization of the lock.
Since the end of the 50 s, after the semiconductor (transistor) technology came into existence, people just applied the technology to locks, and invented electronic locks with various shapes and colors and rich functions. With the development of science and technology, electronic intelligent locks using signal acquisition and processing are developed at home and abroad, and an intelligent lock system with high security performance is developed by combining unique characteristics of human fingerprints, irises and the like with locks.

Along with the development of science and technology and the improvement of people's standard of living, people also are higher and higher to the security performance requirement of tool to lock in practical application to realize personnel's management problem through the tool to lock that evolve on the tool to lock basis has also obtained people's attention. The properties of the lock, such as firmness, safety, confidentiality, reliability, durability, etc., and the price of the lock become the focus of attention. In order to meet the actual requirements of people, a large number of electronic locks based on single-chip microcomputers are produced. Because the singlechip has the characteristics of flexible development, small volume, high integration level and the like, electronic locks developed on the market according to different purposes are various, and generally have the characteristics of small volume, low mutual opening rate, strong practicability and the like. On the basis, software on a computer terminal is used for controlling the electronic lock, so that a personnel management system of a company is established by using the whole software and hardware system of the electronic lock. Therefore, electronic locks are widely used in various industries. At present, the electronic lock market in China still takes W key type and card type electronic locks as leading products. Both the key type and card type electronic locks are introduced in foreign technology, and now dozens of production and supply markets exist in China. The former tends to be eliminated due to some problems caused by the structure of the dial type and touch type electronic locks, and the latter is less adopted in the occasion of multi-bit code combination due to poor sensitivity. At present, the domestic market of high-grade electronic locks is still occupied by foreign products.
However, the electronic lock cylinders commonly found in the market at present have the following two problems: (1) the power supply of the electronic lock cylinder depends on the mains supply, and a user needs to use a special mains supply circuit to meet the voltage requirement of normal work of the electronic lock cylinder, so that the use of the electronic lock in the environment without the mains supply is limited. For example, in the field, such as oil production wells, water injection stations, telecommunication wells, etc., especially in remote locations, the safety requirements are often high, but it is difficult to provide power. (2) The battery is installed on the lock head of part electronic lock, though the potential safety hazard that the system is in the normal open state after the outage has been solved, change the battery on the lock head and generally need dismantle the lock head, brought very big inconvenience for the user. The patent publication No. CN206888714U discloses an electronic lock control device, which is applied in a BMS system including a battery pack and an MCU unit, and a power supply is provided to the system by the battery.
The passive electronic lock is a new important branch in the field of electronic locks, and the most different from the traditional electronic lock (temporarily called as active electronic lock) is that: the inventor adopts the concept of reverse thinking to transfer the necessary working power supply of the electronic lock to the electronic key (called as active electronic key), thereby thoroughly solving a series of inherent problems in the traditional active electronic lock, such as: the system consumes a large number of batteries, needs frequent maintenance, and has the advantages of complex structure, low generalization and standardization degree and higher failure rate. When the active electronic key contacts the passive electronic lock, the power supply (battery) on the active electronic key and the unlocking electronic code are simultaneously led into the passive electronic lock with the built-in microcomputer, and the codes of the two are in accordance, so that the lock can be unlocked. However, the key is still required to be replaced with a battery, and the operation is inconvenient. In the past, people have higher and higher safety requirements, and technicians in the field are keen on the research of safety performance, for example, patent document with publication number CN107180464A discloses an unlocking method and system of a temporary visitor intelligent lock, which solve the potential safety hazard of the temporary/dynamic password of the existing intelligent unlocking method through quadruple security. The quadruple guarantees are respectively the uniqueness of the authorized unlocking equipment/user, the uniqueness of the authorized unlocking position, the limitation of the authorized time and the limitation of the effective time of the two-dimensional code. The unlocking equipment/user can be tracked and identified respectively, the authorization position is limited by management, the visiting time can be controlled, the authorization use time can be managed, and the safety of the intelligent lock in a temporary visiting scene is greatly improved. The technical personnel in the field think that the mode of adopting the active key to open passive intelligence lock has been very convenient, and to the passive technique of no battery, the simplified operation, the research is few, and ever since always, people often use wireless signal transmission information, can not think to be used for transmitting the electric energy.
The invention has the beneficial effects that: the invention comprises a lock body, a lock core arranged in the lock body and a control system. The control system comprises a power supply and communication antenna, a receiving processing unit, a processor, an indicating unit and an unlocking execution unit.
