Problems solved by technology

Regardless of whether it is an abnormal vibration, fire (gas anomaly) warning, etc., it is impossible to notify the key personnel in the affected area at the same time, causing most of the relevant personnel to lose the best evacuation opportunity and causing huge losses.
[0006] Especially in terms of timely notification of fire in high-rise buildings, whether it is a commercial building or a residential building, the basic fire-fighting facilities have completely lagged behind the acceleration of the storey height. When a fire occurs, it still needs to be communicated through people. Wasted precious evacuation time, lost the reliability of the alarm, delayed the timeliness of the alarm, and lost accurate information on the fire source and evacuation route, which made people saddened to see many accidents that should not have happened in the past and in the near future. fire tragedy

example 1

[0035] Example 1. By setting the start-up remote control, the gas abnormality alarm module starts to work and is in the monitoring state.

[0036] The gas alarm detects abnormal gas and starts the alarm: start the transmission of the remote control, so that the relays (1), (2), (3) act in the data received by the remote control; the relay 1 acts, and the on-site alarm sounds, SMS (dial-up) ) alarm; relay 2 acts to trigger the MCU (N1) pulse signal data, digital signal data and analog signal data corresponding to the gas abnormal alarm device, through the CPU: from Zigbee (E) network transceiver module 1 and (F) network transceiver module 1 Wirelessly transmit and transmit data to Zigbee(E) network transceiver module N and 430MHz---490MHz(F) network transceiver module N; corresponding to the voice IC module, send out an alarm voice sound; corresponding to the network alarm displayed by the PC; corresponding to the display screen Zigbee sub-node or area on-site alarm; relay 3 ac...

example 2

[0038] Example 2. By setting and starting the remote control, the abnormal gas alarm module starts to work and is in a monitoring state.

[0039] Zigbee(E) network transceiver module 1 and (F) network transceiver module 1 receive the pulse signal data, digital signal data and analog data transmitted by Zigbee(E) network transceiver module N and 430MHz---490MHz(F) network transceiver module N Signal data, after the CPU carries out data difference optimization: corresponding to the voice IC module, the voice sound of the alarm is issued; the network alarm displayed by the corresponding PC; the Zigbee sub-node or regional on-site alarm displayed by the corresponding display screen; again from the Zigbee (E) network to send and receive Module 1 and (F) network transceiver module 1 wirelessly transmit and transmit data to Zigbee (E) network transceiver module N and 430MHz---490MHz (F) network transceiver module N.

Abstract

The invention discloses a Zigbee abnormal network data transmission method and an alarm device system, wherein the real-time automatic monitoring of a complex environment and region is realized by the mutual emission and reception functions of a Zigbee node and a Zigbee sub-node (monitoring point), the connection of the Zigbee nodes at the inside and outside of a building, the Zigbee self-networking and the transmission of 430MHz-490MHz emitting and receiving module. A double-network transmission state of transmitting the same content data through different networks and different orders and data difference optimal fusion of a crossing node CPU (Central Processing Unit) are used for correcting the signal attenuation and data loss generated by Zigbee network multilevel transmission to guarantee the perfect abnormal data transmission state and improve the activity and accuracy of real-time monitoring data.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a Zigbee abnormal network data transmission method and an alarm device system. Background technique [0002] With the changing trend of the global climate and environment, the extreme natural state is constantly emerging, which has constantly threatened human beings. In recent years, strong earthquakes, mudslides and tsunamis have repeatedly destroyed precious lives on a large scale. [0003] When the leap of science and technology brings people to enjoy happiness and reduce physical labor, human beings rely too much on various electric machinery; when luxurious decoration brings human beings a glorious moment, fires caused by electrical failures and brutal construction, etc. How many precious lives have been swallowed. [0004] A high-rise building stands like a concrete forest in each city. In order to display the regional business card, the high-rise buildings in each ...
