Spatial photometric distribution intelligent monitoring system based on Zigbee

Abstract

The invention discloses a spatial photometric distribution intelligent monitoring system based on Zigbee, comprising: various sensor nodes in a Zigbee wireless sensing network, a converging node for transmitting the monitoring data and a host computer system to realize the functions of receiving, processing, saving and displaying data. Each sensor node comprises a first micro-control module, a first power supply module, a temperature and humidity sensing module to monitor the environment of the sensor node, a luminance sensing module to monitor the burning state of a to-be-detected lamp, and a first radio frequency receiving and sending module. The converging node comprises a second micro-control module, a second power supply module, a serial interface conversion module, and a second radio frequency receiving and sending module. According to the monitoring system of the invention, a low power consumption wireless sensing network technology is utilized to cooperate with a high precision temperature and humidity sensor and a luminescence sensor so that real time monitoring, temperature and humidity data recording and alarming over the allowed temperature could be possible for an entire photometric distribution testing system. At the same time, control over the burning state of a to-be-detected lamp can also be realized.

Description

technical field [0001] The invention relates to an intelligent monitoring system, in particular to a Zigbee-based intelligent monitoring system for spatial photometric distribution used for monitoring the ambient temperature and humidity of a spatial photometric distribution meter and the illuminance of measured lamps. The system belongs to the field of electronics and the Internet of Things. Background technique [0002] The goniophotometer is a large-scale device used to measure the photoelectric parameters in all directions of the tested lamp space. The device is installed in a dark room with a space size of 7×7×15 meters. According to the requirements of national standards, during the test process, the temperature of each point in the dark room, especially the temperature around the tested lamps and photometric probes, needs to be strictly controlled within the range of 25°C ± 2°C. In a darkroom environment, traditional temperature and humidity meters cannot continuously...
