Abstract

The invention is microcomputer intelligent lock system, which mainly made up of keyboard circuit, bit driving circuit, microprocessor, and lock head electromagnetic driving circuit, memory, protecting circuit, power control circuit. The keyboard circuit, bit driving circuit, and the memory are connected to the microprocessor directly; the buzz instructing light circuit, lock head electromagnetic driving circuit, power control circuit, and the protecting circuit are connected to the bit driving circuit; the protecting circuit controls the read and write of the memory; the microprocessor is connected with a PC to change the cipher code; the direct current electric signal uses the thyristor to control the alternate current power of the electric lock; a returning hook device is arranged in the electric lock for ensuring the safety when closing the door. The lock uses electron switch, has no arc or spark; the inputted cipher code may reach to 16 bits, it can change the cipher code online.

Description

technical field

[0001] The invention relates to an electronic control device, belonging to the fields of electronic technology and information technology. Background technique

[0002] Nowadays, general-purpose mechanical locks generally have shortcomings such as easy duplication and weak insurance performance. Some people can even open most mechanical locks without a key; Lost, the product is not universal, and it is inconvenient to use. Existing multiple coded locks also have some disadvantages: the simple switch type coded lock has few code digits, inconvenient modification, and weak security. The combination lock of the digital gate circuit is inconvenient to modify, cannot be automatically detected, and lacks intelligence. The CUP controls the combination lock of the computer board and cannot be connected with the personal computer, so the intelligence is limited, and it is difficult to meet the requirements of family intelligence. The electric locks commonly used in...
