Special-type intelligent door dual-system control device

Abstract

The invention discloses a special-type intelligent door dual-system control device, and the device comprises the commercial power, a switching power supply, a standby power supply, a commercial powerdetection device, an access controller and an electronic lock. The access controller comprises a controller CPU, and the commercial power detection device comprises a low voltage conversion unit. Theaccess controller further comprises an IGBT dual-power switching unit, an alarm unit and a remote communication unit. The IGBT dual-power switching unit comprises an IGBT electronic switching switch,which greatly improves the commercial power compared with the switching speed of a relay, thereby improving the switching speed of the commercial power and the standby power supply, and truly achieving the uninterrupted supply of the power supply. The device is short in switching time, is high in reliability, has no problem of switching sparks, and is very good in application prospect, can achievethe starting of an electronic lock remotely through the access controller, achieves the remote control of the opening of the door and the emergency opening of the access control system in case of emergency power failures. When the fire or extreme danger occurs, the ambulance personnel can perform the emergency opening without approaching.

Description

technical field [0001] The invention relates to the technical field of prison access control systems, in particular to a dual-system control device for special intelligent doors. Background technique [0002] With the continuous development and progress of social economy and science and technology, all walks of life have more and more strict requirements on power quality and power supply reliability. Especially for some important power-consuming departments or equipment, even if the power failure time is milliseconds, it may bring catastrophic destruction to the enterprise or equipment. Therefore, people's demand for high-quality continuous power supply is becoming more and more urgent. [0003] In the prison security system, the access control system in the prison is the most important part of the prison management. At present, most of the access control of the prison has adopted the access control management system, and the most important parts of the access control manage...

Problems solved by technology

[0003] In the prison security system, the access control system in the prison is the most important part of the prison management. At present, most of the access control of the prison has adopted the access control management system, and the most important parts of the access control management system are the access control controller and the electronic lock. As the executive body in the access control, the access control controller is the core of the access control management system. It is a controller used in the management of high-security channels. It has very strict requirements on power supply. The controller needs to use the backup power supply for stable power supply, and the dual power supply system needs to be switched without interference, so the dual power supply switching system has emerged as the times require. When the mains power in use fails, it can automatically identify and quickly switch to the normal backup power supply to ensure uninterrupted power supply, and when the mains power returns to normal, it can switch the user circuit back to the mains, reducing the access control system. The cost of electricity consumption and the physical loss of the backup power supply can realize the control of the backup power supply in the dual power supply system that can be started in emergency situations such as fire or no electricity in the mains; in addition, the existing access control system does not have a remote communication function. It is impossible to remotely control the opening of the access control controller and the emergency opening of the access control system in the event of an emergency power failure. When a fire or extreme danger occurs, the ambulance personnel can remotely open the emergency opening without approaching; but the existing dual power switching system has some defect:

[0004] Because the existing dual power supply switching unit uses relays to switch between the mains power supply and the backup power supply, the switching speed of the relays is slow, the reliability is low, and there are problems of switching sparks

In addition, the existing access controller does not have the remote control function. When there is an abnormal or emergency situation such as fire on the local side, it cannot be controlled remotely, and there is no alarm reminder function.
