变电所无线测温监控系统

　　变电所无线测温监控系统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.

　　Software low power consumption implementation, when the bus is in a small current state, the magnetic induction coil to obtain less energy, so the entire circuit power is very low, so not only requires low power chip, software design is also particularly important. Low power program design, through the sleep of single chip microcomputer and wireless transceiver and the shutdown of peripheral circuit, make the whole circuit high current is not more than 30ms, the power consumption of wireless transmission is not more than 500ms.
