Embodiment Construction

[0026] figure 1 It is the overall frame diagram of the water gate safety monitoring system based on the wireless network of the present invention. The system can be divided into three parts, the first part is the data acquisition system, as shown in figure 11; the second part is the data transmission system, as shown in figure 12; the third part is the sluice remote monitoring system, as shown in figure 13 shown. The data acquisition system 11 is composed of parameter acquisition nodes, video acquisition nodes, routing nodes and coordinator nodes. Water level sensors, flow rate sensors and sluice level gauges are used to collect sluice structural parameters and environmental parameters. Through the 2.4GHz ISM frequency band, they form a ZigBee wireless system based on IEEE 802.15.4 technical standards and ZigBee network protocols with upper-layer routing nodes and coordinator nodes. Network, the routing node expands the network coverage by connecting the neighbor nodes, assi...

Abstract

The invention discloses a wireless-network-based water gate security monitoring system, belonging to the field of security monitoring of water transport engineering. The wireless-network-based water gate security monitoring system comprises a data acquisition system, a data transmission system and a remote monitoring scheduling system, wherein the data acquisition system comprises a parameter acquisition node, a video acquisition node, a route node and a coordinator node, and the remote monitoring scheduling system comprises a database server system and a monitoring scheduling center. According to the invention, a wireless acquisition technology and a wireless transmission technology are adopted to carry out acquisition, transmission, processing, display, control and other operation on environment parameters, structural parameters and video data of a water gate, and a gate is opened and closed according to an operating instruction. According to the invention, a wireless sensor network technology, a third generation wireless communication technology and a video monitoring technology are applied to water gate management, all the operations from information acquisition, transmission and storage to information processing are carried out in digital information image forms, and thus, the efficiency and the security in water gate management are greatly increased.

Description

technical field [0001] The invention belongs to the cross-field research on the combination of safety monitoring of water transport engineering, embedded system and wireless communication technology, and in particular relates to a water gate safety monitoring system based on wireless network. Background technique [0002] As an important water conservancy infrastructure, sluices play a pivotal role in shipping, irrigation, water supply, flood control, hydroelectric power generation, regulating river flow and improving the water environment. However, the current sluice monitoring system mainly uses wired methods, and the wired distributed sluice monitoring system Usually Ethernet or field bus network is used as the network connection mode of the monitoring and control system, and shielded network cable, optical fiber or cable is used as the wired communication medium of the control system. Although individual projects use wireless methods, they also mainly use digital radio s...
