Embodiment Construction

[0191] Please refer to the attached figure 1 As shown, the device of the present invention corresponds to three kinds of terminals by three communication modes, and together with the central controller (1), they form a tree structure; the first level is the central controller, which is responsible for receiving alarms and managing terminals; the second The second level is the Global System for Mobile Communications GSM alarm (2), either a mobile communication terminal or a telephone terminal. Because they can transmit information over a long distance, they can directly report to the central controller; the third level is a radio alarm ( 3), because its alarm distance has a certain limit, so it can only alarm to the nearby second-level terminal, and then the second-level terminal forwards the alarm to the central control room.

[0192] The system consists of network, terminal, mobile communication, telephone communication and public frequency radio. The system consists of hardw...

Abstract

The present invention relates to remote alarm device in radio technology field, and is especially one kind of remote alarm system and method for power failure with alarm site locating function. The remote alarm system consists of network, terminal and other hardware, and one three order tree structure system consists of three kinds of terminals separately for mobile communication, telephone communication and common radio communication and central controller. The alarm system has alarm, automatic polling, sleep, restoring and other work modes. The present invention has the advantages of reliable alarm, long alarm distance, high intelligence, low cost, no alarm blind point, etc. The equipment in the system constitutes one LAN with simple and reliable communication.

Description

technical field [0001] The invention relates to a remote transmission alarm device in the radio field, in particular to a remote transmission alarm system and an alarm method for an accidental power failure, which is applied to a remote transmission alarm when an unexpected power failure occurs in a power grid, and locates an alarm location. Background technique [0002] At present, the remote transmission alarm for accidental power failure usually utilizes telephone lines as the medium for alarm signal transmission. For this reason, the alarm cannot be laid where there is no telephone line coverage. There are also alarms that utilize radio signals to alarm, but the alarm distance is quite limited. Moreover, the alarms are often independent of each other and do not form a network, so it is difficult to control them uniformly. Contents of the invention [0003] In order to overcome the above disadvantages, the main purpose of the present invention is to provide a system th...
