Problems solved by technology

[0006] The purpose of the present invention is to provide a bus fire early warning and window toughened glass burst remote control system, to solve the early warning of air-conditioned bus fire and when the safety door cannot be opened, the driver has an accident or the fire burns out the line and the window cannot be completed. In the case of tempered glass bursting, the bus center monitors in real time through remote video, sends a remote bursting command, and transmits the command to activate the bursting device through the ZigeBee wireless network to protect the lives of bus passengers

Embodiment

[0027] Embodiment: The system consists of an intelligent gateway, a ZigBee monitoring node, a 3G network, and a bus remote monitoring center computer. The ZigBee coordinator module of the intelligent gateway and the ZigBee module of the ZigBee monitoring node form a ZigBee network, and communicate wirelessly through the ZigBee protocol; the intelligent gateway is connected to the bus remote monitoring center computer via the 3G module and the 3G network.

[0028] The intelligent gateway is composed of Da Vinci processor, ZigBee coordinator module, PTZ camera, video decoder, DDR2 SDRAM, 3G module and display alarm circuit. Its Da Vinci processor uses TMS320DM6446, TMS320DM6446 is a 32-bit processor, internally integrates TMS320C64x+DSP and ARM926EJ-S MPU dual-core structure, integrates the advantages of DSP and RISC technology, its rich user interface, high-speed processing performance, powerful operation System support and low power consumption are widely used in multimedia ne...

Embodiment 2

[0037] 1. When the real-time requirements are not high, GPRS can be used instead of 3G, but only text messages and still pictures can be sent;

[0038] 2. The ZigBee network for fire monitoring in the vehicle can be implemented using CAN bus, 485 bus and other wired monitoring points.

Abstract

The invention relates to a bus fire early warning and armored window glass bursting remote control system, comprising an intelligent gateway, a ZigBee network, a 3G network and a remote bus monitoring center. The intelligent gateway comprises a Leonardo processor with an ARM+DSP double-core architecture, a video collecting and decoding module and a display alarming module; the ZigBee network is composed of a coordinator node and a plurality of monitoring nodes. Each monitoring node monitors fire information such as temperature, smoke and gas, gives an alarm and controls the bursting of the armored glass in the case of emergency; the 3G network is used for transmitting video information, monitoring data and commands of the bus monitoring center which have been encoded and compressed. The ZigBee network combines real-time data monitoring with 3G network remote video transmission, thus achieving fire pre-warning and multistage alarming functions; in the case of emergency, the monitoring center monitors fire situation through video and remotely starts the bursting of the armored window glass, thus allowing passengers to escape as soon as possible, and protecting life safety.

Description

technical field [0001] The invention relates to a bus fire early warning and window tempered glass burst remote control system, in particular to a bus fire early warning and window tempered glass burst remote control system based on ZigBee fire monitoring and 3G video real-time transmission. Background technique [0002] In recent years, there have been many bus fire accidents in some parts of the country, and some even caused a large number of casualties, which has caused a major impact on the society. Buses belong to densely populated public places, and many air-conditioned buses have fully closed windows. In such a relatively closed and narrow space, once a fire accident occurs, it is very easy to cause heavy casualties. Especially under the situation that the fire makes the safety door unable to open, how to make passengers escape as soon as possible and avoid heavy casualties is a problem that needs to be considered urgently. [0003] From an accident involving a vehic...
