Wireless Temperature Monitoring System for Substation

Description :

　　Circuit design and dual power management technology for wireless temperature monitoring system in substations

　　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.

　　Product Introduction

　　Function:

　　ARTM Pn wireless temperature measurement device: The ARTM Pn wireless temperature measurement device can be installed separately in high-voltage cabinets and low-voltage drawer cabinets. Each device can receive data from 18 sensors, and sensor models can be selected as ATE100, ATE200, or ATE300. The device is equipped with a 485 interface, which can upload the collected temperature data to the monitoring center.

　　ARTM8 Temperature Inspection Instrument: The ARTM series temperature inspection and control instrument is suitable for measuring and controlling one or multiple temperatures, mainly used for temperature inspection, measurement and control in thermal power plants, hydropower stations and other occasions. Measure the temperature of Pt100 in 8 channels, and any channel can also be shielded. Each channel temperature measurement corresponds to 2 alarm segments, and the relay output can be set to any alarm direction and value.

　　Wireless temperature measurement centralized collection touch screen: The wireless temperature measurement touch screen can be embedded and installed in high-voltage cabinets and low-voltage drawer cabinets. Each device can receive data from 240 sensors and can be optionally used with ATE100, ATE200, and ATE300 sensors. The device is equipped with a 485 interface and an optional Ethernet port, which can upload the collected temperature data to the monitoring center.

　　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.
