Device and method for controlling remote start of sensors on basis of passive RFID labels

Abstract

The invention relates to a device and method for controlling remote start of sensors on the basis of passive RFID labels. The device comprises a data terminal system, an RFID label, an amplifier system and a self-power supply system, wherein the data terminal system is used for emitting a wireless radio-frequency signal; the RFID label is wirelessly connected with the data terminal system and is used for receiving the wireless radio-frequency signal emitted by the data terminal system and converting the wireless radio-frequency signal into induction current; the amplifier system comprises a triode, a base resistor connected with the base of the triode and a collector resistor connected with the collector of the triode; and the self-power supply system is used for providing electric energy.According to the device and method, the conducting state of the triode is controlled through base current provided for the triode by the RFID label, and the triode is connected with a power supply management unit of a sensor and the self-power supply system, so that energy consumption of the sensor in non-work state is stopped.

Description

technical field [0001] The invention relates to the technical field of passive RFID tags and sensors, in particular to a sensor remote start control device and method based on passive RFID tags. Background technique [0002] Radio Frequency Identification (RFID) systems and sensor systems are important support systems for the Internet of Things. The RFID system is mainly used in the identification, positioning and tracking of target objects, and also has the functions of data collection and transmission. The sensor system is used for various environmental perception and information collection such as temperature, humidity, light, motion, pressure, stress, distortion, position, flow velocity and gas. As the application environment becomes more and more complex, the data become more and more diverse, the requirements for precision are getting higher and higher, the number of sensors is increasing, and the cycle of environmental monitoring is getting longer and longer. The en...

Problems solved by technology

However, the power consumption of the sensor is continuous. Even if the sensor is in the data collection interval (non-working state), the sensor still needs to consume battery energy to maintain the waiting state of the basic components of the sensor.

Although the energy consumption in the non-working state is much lower than the data acquisition and transmission state (working state), the non-working state lasts for a long time, and the cumulative energy consumption will also account for a large proportion
