Embodiment Construction

[0014] specific implementation plan

[0015] The hardware configuration of the present invention is that each user configures an alarm controller, and a transponder is set in each small block center including a plurality of alarm controllers, and all transponders access the alarm through a mobile communication network (such as a GSM mobile communication network) center.

[0016] Such as figure 1 As shown, the wireless receiving module of the alarm controller receives signals from various intrusion detectors, and after these signals are received and demodulated by the module, the output data is sent to the I / O port of the single-chip microcomputer (microprocessor). The MCU decodes and processes the data according to the designed program. When an alarm is required, start the carrier frequency transmission through one I / O port, and the other I / O port modulates the carrier frequency with the coded data to be transmitted, and sends an alarm signal to the transponder. It is also ...

Abstract

The method includes the following steps. (1) The large guarding area is divided into many small plots. (2) One repeater with wireless receiver is setup at the central position of each plot. But, the different frequencies are allocated for the repeaters in adjacent plots. (3) One wireless alarm controller with same emissino frequency is allocated for each user in each plot. (4) The repeaters in all plots are networked through the mobile communication network. (5) The alarming signal forwarded by the repeater is transferred to the alarming center. The invention possesses the advantages of both the wired network and the wireless network, and avoids their disadvantages, providing the reliable signal, the benefit without need of wiring.

Description

technical field [0001] The invention relates to an alarm network, in particular to a method for large-scale networking of anti-theft alarm devices. Background technique [0002] There are many kinds of networking methods for traditional anti-theft alarm devices. According to the transmission route of alarm signals, they can be divided into two categories: wired networking and wireless networking. Each user alarm controller is connected to the The alarm center forms an alarm network. [0003] The advantage of wired networking is reliable signal transmission, but the disadvantages are large amount of wiring engineering, complex construction, high cost, inconvenient hiding of lines and alarm devices, easy to be damaged, and inconvenient for large-scale networking. The advantages of wireless networking are that no wiring is required, the installation is convenient, the alarm device is easy to hide, and it is not easy to be damaged. The disadvantage is that the transmission powe...
