Embodiment Construction

[0037] The present invention will be further described below in conjunction with drawings and embodiments.

[0038] Such as figure 1 As shown, the museum Internet of Things environment monitoring system involved in the present invention includes three levels of wireless sensor nodes, central control base stations, and central monitoring modules. The sensor nodes are connected with the central control base station through wireless communication, and the central control base station is connected with the central monitoring module through Internet / GPRS.

[0039] Such as figure 2 Shown, be that the wireless sensor node of the present invention comprises: processor module, Zigbee module, signal converter, power supply module, communication interface, and multiple intelligent sensor (temperature and humidity sensor, CO 2 , SO 2 , NO 2 Gas sensor, light sensor, vibration sensor, PH value sensor, air pressure sensor, etc.). Sensor nodes collect data, pass through a signal conver...

Abstract

The invention provides a deployment method of wireless sensor nodes of an environmental monitoring system in a museum internet of things. The method comprises the following steps of: at first, establishing a model of a wireless sensor node deployment problem; and then deploying wireless sensor nodes by using an improved genetic algorithm. The invention has the advantages that: in a complex transmission environment of a museum, the sensor nodes are optimally deployed according to the improved genetic algorithm, and the efficient and energy-saving environmental monitoring system of a Zigbee ad hoc network and a wireless sensing network which is suitable for a museum environment are established, so that the defects in the traditional process of cable wiring of difficult arrangement of collection points, high system cost and difficulty in installation and maintenance are avoided. Furthermore, monitoring nodes are high in fitness and flexible to apply, do not influence collection distribution in an exhibition room and have strong self-organization and expansibility.

Description

technical field [0001] The invention relates to a wireless sensor network, in particular to a method for deploying wireless sensor nodes in a museum Internet of Things environment monitoring system. Background technique [0002] Wireless Sensor Networks (WSNs for short) is the product of the combination of computing, communication and sensor technologies, and has become an active research branch in the field of computer science. With the advancement of wireless communication technology and electronic device technology, the development of low-cost, low-power, small-volume, and multi-functional (sensing, processing, and communication functions) sensors has been promoted, making it possible to develop low-cost sensor networks, thereby Make it have a wider application field. [0003] Wireless sensor network is regarded as a development direction of environmental monitoring and building monitoring. It does not require fixed network support, and has the characteristics of rapid ...
