Cabinet door control alarm

Abstract

The invention discloses a cabinet door control alarm, which comprises a main control circuit, a power source and cabinet door state detection circuit, a motor lock motor driving circuit, an alarm input-output circuit, an alarm circuit and a multimedia message module integrated circuit (IC7), wherein the main control circuit is used for controlling each circuit; the power source and cabinet door state detection circuit is used for supplying a power source to the circuits and detecting an opening and closing state of a cabinet door; the motor lock motor driving circuit for supplying a power source started or shut down to a motor lock motor and enabling a motor lock to move towards the opening or closing direction; the alarm input-output circuit is used for collecting each alarm signal and giving out alarm command; and the alarm circuit is used for sending out sound and light to give an alarm and sending out the alarm signal to users near the cabinet door. The multimedia message module IC7 is used for achieving remote connection between the cabinet door control alarm and a cabinet door controller and enabling the cabinet door controller to know about the state of the cabinet door control alarm and achieve remote control of the cabinet door control alarm. The cabinet door control alarm can carry out remote control and remote alarm to the cabinet door, multiple unlocking secret-key control is adopted, and the safety performance of a cabinet door control system is greatly improved.

Description

technical field [0001] The invention relates to a cabinet door control alarm, which is used to support the control and alarm of electric control locks, motor locks and electric mortise locks. Background technique [0002] Judging from the current market, there are no products that apply remote control and alarm to cabinet door lock control and alarm. Most of them are alarms that only play an alarm role, and lock controllers that only play a role in control. [0003] As far as alarms are concerned, the common alarms at present include object vibration alarms, fixed telephone line dial alarms, infrared alarms, door magnetic wireless alarms, etc. All kinds of anti-theft alarms have the following disadvantages: 1. The information is single, and comprehensive alarm information cannot be sent, and false alarms and missed alarms (no alarms) are prone to occur. For example, traditional infrared detectors will trigger alarms when encountering cats, dogs, mice walking, curtains being...

Problems solved by technology

[0003] As far as alarms are concerned, the common alarms at present include object vibration alarms, fixed telephone line dial alarms, infrared alarms, door magnetic wireless alarms, etc. All kinds of anti-theft alarms have the following disadvantages: 1. The information is single, and comprehensive alarm information cannot be sent, and false alarms and missed alarms (no alarms) are prone to occur.

For example, traditional infrared detectors will trigger alarms when encountering cats, dogs, mice walking, curtains being blown by the wind, clothes shaking, hot and cold air convection, fans shaking their heads, etc., which will generate false alarms; Small animals that touch the object that the vibration alarm is protected from will cause false alarms; ordinary wireless alarms will cause false alarms due to electromagnetic interference in the air, and 315M or 433M jammers are used when thieves invade (this is currently the most commonly used) Intrusion method), all the wireless anti-theft system communication will be disabled! The alarm cannot be effective (that is, missed alarm); and the fixed telephone line dial-up alarm, because the telephone line is easily damaged, once the telephone line is damaged, the system will not be able to call the police, that is, a false alarm will occur

2. The alarm distance is limited, and some alarms only have on-site sound and light alarms, without remote alarm functions, and can only be used for short-distance anti-theft or sight, hearing, limited distance and wired anti-theft

3. If the alarm often sends false alarms, the alarm sound from the on-site acousto-optic alarm is louder, which will cause noise interference to the on-site environment

These two opening methods are all single-authority opening methods, and have the following disadvantages: 1. The digital keyboard input password opening method is easy to be detected by an intruder through technical means to unlock the unlock password, and finally realizes illegal unlocking

2. The opening method of the wireless remote control is easy for the intruder to crack the password of the remote control through the high-tech code reader, so that the code reader becomes a remote control, which can control the door lock control system arbitrarily and open the door lock
