Data transmission and control method for wireless self-organized network control system

Abstract

The invention relates to a data transmission and control method for a wireless self-organized network control system. The method comprises a bottom-to-top data transmission method for monitoring information and a top-to-bottom control method for a user. The method adopts a collector, a controller and other terminal subsystems, together with a wire data transmission technology at a monitoring nodeand a wireless data transmission technology between the monitoring node and a central base station, transmits the monitoring information from the collector in a bottom-to-top manner to a user mobile phone, and the user controls the controller in a top-to-bottom manner. Due to the adoption of the method, information amount in data transmission is small, the transmission is fast, a great amount of wire circuit arrangement is eliminated, the operating cost is saved, and the safety is high; and due to the small amount of wireless signal transmission, low interference and high reliability are achieved.

Description

Technical field: [0001] The invention relates to the field of intelligent control, in particular to a data transmission and control method for a wireless ad hoc network control system. Background technique: [0002] At present, the wireless ad hoc network control system generally includes a collector, a controller, a monitoring node, and a central base station. The data transmission and control methods of the wireless ad hoc network control system in the prior art generally adopt a technology similar to Zigbee, which is applied to short-distance Wireless communication technology between various electronic devices at a low transmission data rate within a wide range. Compliant with IEEE802.15.4 protocol, it is suitable for building a wireless local area network for family and industrial short-distance communication. [0003] The information sent by the system is transmitted through the wireless signal transceiver module installed on the collector (child node) and monitoring n...

Problems solved by technology

[0006] Second, ZigBee technology is used to transmit point-to-point wireless signal data from the collector to the monitoring node (gateway). In this way, a wireless signal transceiver module needs to be installed on each collector, and the number of collectors under the same monitoring node is large. Under normal circumstances, the amount of data received and processed by monitoring nodes is relatively large, and a large ad hoc network control system of a residential area with more than 1,000 households contains many monitoring nodes, and each monitoring node needs to communicate with the center The base station communicates, so the amount of data received and processed by the central base station is larger, which seriously affects the speed of data transmission

[0007] Third, the wireless ad hoc network control system using ZigBee technology uses R485 bus, or broadband network optical cable or telecommunication telephone cable for wired data transmission between the monitoring node and the central base station. system, it is necessary to lay a large number of lines, the construction is complicated, the cost is high, the line crossing distance is limited, and because the line laying is a public entity facility, it is easy to be damaged and the safety is low

[0008] Fourth, a wireless ad hoc network control system includes many monitoring nodes, and each monitoring node includes many collectors and controllers, and each collector must have a wireless signal receiving and transmitting module, and the difference between them is The code address between users is coded by 12-bit binary dial switch. When there are too many wireless signal receiving and transmitting modules, and they all transmit data on the same channel, in the peak period, the wireless signal data transmission between users is extremely difficult. Prone to collusion, interference, false alarms, channel congestion during peak hours, etc.

[0009] The above defects are actually problems that existing network communication technologies such as ZigBee cannot effectively solve, which is also an important reason for the low popularity of the current intelligent community security system.
