变电所电气接点无线测温装置

　　变电所电气接点无线测温装置Circuit design and dual power management technology

　　The wireless temperature measurement and early warning system of high-voltage substation adopts dual-power management technology to manage the intelligent temperature sensor and the wireless transceiver module respectively, which can reduce the power consumption and improve the service life of the sensor. Due to the small working current of temperature sensor, ultra-low power single-chip microcomputer and peripheral circuit, 3.6V, 3000mA battery is mainly used for power supply in the circuit design process. The large continuous discharge current and large pulse discharge current of the battery can reach 150mA and 300mA respectively. Calculated according to 80% battery utilization rate, Life expectancy can reach more than two years. Through the control of single chip microcomputer to the current do not need to work on the parts of power protection, effectively improve the utilization rate of electricity. In addition, in order to effectively prolong the service life of the wireless temperature measurement early warning system in high-voltage substation, under the premise of meeting the operating frequency of equipment, a smaller working frequency can be selected to reduce the power consumption of the single-chip microcomputer. Moreover, energy consumption should also be emphasized in the design of peripheral circuits and equipment selection.

　　System overall scheme design

　　The wireless temperature measurement system proposed in this paper includes a main temperature gathering unit and several subordinate temperature sensing units. System to use more than a master from the way, can be realized at the same time for multiple real-time temperature measuring device under test, from temperature sensing element is in contact with the object under test to measure the temperature of the object to be tested, from temperature sensing unit by wireless communication mode will be collected temperature data sent to the main unit, the temperature collection unit and the temperature of the socket connection will bring together information sent to the host. The slave temperature sensing unit in the wireless temperature measurement system proposed in this paper is powered by lithium battery, which is convenient for on-site installation. Low power MCU is used to collect temperature information of the measured object and lithium battery power information in its ultra-low power consumption way, so that the battery can be used for a longer time; The main temperature collection unit adopts USB hardware socket and Modbus software interface to connect with the host, which makes the host configuration more flexible. The master-slave module communication has two modes of air matching and active reporting to ensure the communication stability between the master temperature gathering unit and the slave temperature sensing unit. The two working modes can be selected according to the requirements of use to ensure the stability of the equipment under the condition of low power consumption.
