Description

security alarm system

Technical field:

The utility model relates to the field of security technology, in particular to a security alarm system.

Background technique:

In today's society, security alarm systems have been more and more used in homes, schools, enterprises and other places. The security alarm system can detect intruders at the first time and send out an alarm to attract the attention of people in the place, so as to take timely measures. Measures to reduce unnecessary losses. Yet the alarm system generally can only play the effect of warning, can not limit to some extent or record its physical characteristics for the intruder, moreover only can play the effect of warning when someone is present, if people expect themselves to be able to Keep abreast of and monitor the security situation in your home, school or business, then you can't be satisfied. Therefore there are some deficiencies in the existing security alarm device design.

Invention content:

The utility model provides a security alarm system, which can be used for security alarms in families and schools.

The concrete technical scheme of the utility model is as follows:

A security alarm system, comprising a main controller, an infrared camera and a sensor, the infrared camera and the sensor are respectively connected to the main controller, the main controller includes a main control chip, and a memory connected to the main control chip, a GSM module, Rolling code receiving module, camera interface module, indicating module, web port and power management module.

The sensors include a shock sensor, a human body pyroelectric sensor and a door magnet.

The indication module includes a system power indicator light, a system error indicator light, a normal working indicator light, an arming and disarming indicator light, and a buzzer alarm indicator.

The main control chip adopts ARM Cortex-A8; the memory adopts Nand Flash; the GSM module adopts BENQ M22.

The system uses a lithium battery and the mains power supply together, and the power management module can realize the switching power supply between the lithium battery and the mains power. The main controller of the system can communicate with mobile phone or PC.

The beneficial effects of the utility model are as follows:

1. In the security alarm system of the present utility model, the main control chip adopts an ARM processor, and uses a telecom mobile platform for information transmission, which greatly improves the system processing speed and enhances the real-time performance and reliability of the system.

2. All the sensors of this utility model use a 315MHz rolling code wireless transceiver module to communicate with the main controller, which is convenient for function expansion, and the security alarm system is easy to install without wiring.

Description of drawings

Fig. 1 is a structural schematic diagram of the security alarm system of the present invention.

Figure 2 is a schematic diagram of the main controller structure.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the security alarm system of the present utility model includes a main controller, an infrared camera, and sensors. The sensors include vibration sensors, human body pyroelectric sensors, and door magnets. Carry out functional expansion.

As shown in Figure 2, the main controller is mainly composed of the main control chip, memory, GSM module, rolling code receiving module, camera interface module, indicating module, web port and power management module. Among them, ARM Cortex A8 is used as the main control chip; the memory uses Nand Flash to store information such as user face information, system password and alarm number; the GSM module uses BENQ M22 to communicate with the mobile phone through the mobile platform; rolling code reception The module is used to receive control signals such as human body pyroelectricity, door magnetism, and wireless remote control; the camera interface module is used for communication between the infrared camera and the main control chip; the indication module includes system power indicator lights, system error indicator lights, Normal working indicator light, arming and disarming indicator light, and buzzer alarm indication; the web port is used to connect to the Internet for remote configuration and data reception of the device; The operation of the device, the power management module can realize the switching management between the battery and the mains.

The working process of the system after carrying the software is as follows: When the main controller receives signals from the vibration sensor, human body pyroelectric sensor or door sensor, etc., it controls the infrared camera to sample the monitoring screen, and uses the main control chip to use wavelet analysis based on Haar characteristics. Method for analysis, first use generic feature matching to divide the face from the image, and then compare the stored face features of legal people, if it is confirmed that they do not belong to legitimate customers, use door magnetism to lock and call the police and use The main control system captures pictures and location information and stores them in memory, and sends them to mobile phone users through the GSM network. Users can also use mobile phones to connect to the system through the GSM network, use computers to connect to the system through the Internet, or use the remote control to set up and control the system, such as arming, disarming, requesting to send on-site photos, setting new passwords, setting alarm numbers, etc. .
