Problems solved by technology

[0003] The present invention solves the problem that the wireless sensor network node cannot detect its own energy consumption and its own node failure. When a certain node in the wireless sensor network cannot work normally, other nodes will continue to send information to the node without knowing it. node, which is not conducive to the energy saving of the entire network, and is not conducive to prolonging the service life of the entire network. A Zigbee wireless sensor network node energy consumption and fault detection device is provided, which mainly includes sensor sockets, signal amplification modules, working status Indication module, high-frequency transmission module, energy consumption and fault detection module, battery / power supply module and serial port output module; said energy consumption and fault detection module made up of MSP430 single-chip microcomputer through high-sensitivity sampling resistance to sensor node trunk voltage Carry out sampling to realize energy consumption detection and fault detection of wireless sensor network nodes; that is, conduct voltage sampling on the high-frequency transmitter module with CC2530 as the main chip through the sampling resistor; pass the real-time sampled information to the management terminal through the serial port output module , which has reached the real-time reading of energy consumption information of the sensor at the management end; while sampling the voltage of the high-frequency transmitting module, the voltage value and sampling time of each acquisition are stored and the collected voltage value is compared with the preset value in the MSP430 Compared with the maximum operating threshold voltage and the minimum threshold operating voltage, if the sampled voltage value is significantly higher than the maximum operating threshold voltage or lower than the minimum operating threshold voltage, it indicates that the wireless sensor network node has failed, because the MSP430 stores the voltage of each sampling Value and sampling time, so you can read each sampling information and time through the serial port output module, which is convenient for network managers to analyze the crux of the network failure in time to improve the network in time; use the A / D converter integrated in the MSP430 microcontroller to The periodically collected battery power information is converted from analog to digital, and the converted digital signal is compared with the preset minimum battery power threshold. When the threshold is lower than the threshold, the MSP430 sends the information to the management terminal and other wireless sensor network node; and integrate the sensor module and the high-frequency emission module, after the temperature and humidity information and the light intensity information are respectively collected by the temperature and humidity sensor and the light intensity sensor in the sensor module, they are transmitted to the management terminal through the high-frequency emission module
