In a wired measurement mode, the work of laying the cable is very complicated, the field construction environment is severe, the lifting monitoring signal is easily interfered by various factors, the cable is easily broken by a smashing method, and the potential safety hazard is very large. In the wireless measurement mode, the wireless transmission monitoring equipment powered by a battery is generally adopted, the structure is small and independent, and the interference of site construction is hardly caused. Currently, a wireless measurement mode is generally popular. Representative international systems include the american Campbell Scientific CR-10 system, which is used by most of the world monitoring equipment manufacturers (including kykang, SINCO, ROCTEST, etc.) as the acquisition unit of its automation system, the data acquisition instrument 100 of the australian database company, the american Geomation 2380 system, and the italian ISMES institute GPDAS system. However, in the wireless measurement mode of lifting deformation, the charging time of the equipment is about 8 hours generally, the equipment can only continuously work and run for 3 to 4 days after being charged every time, and the monitoring efficiency of the equipment cannot meet the continuous monitoring requirement on the site.

The lift detection unit 22 may be a lift sensor, and the alarm unit 23 may be a light alarm.
The utility model discloses a RFID mode is for lifting the power supply of detection sensor, simple structure, and convenient to use can satisfy the on-the-spot continuous monitoring requirement. RFID (Radio Frequency Identification) is commonly called "electronic tag", and is a non-contact automatic Identification technology that automatically identifies a target object and obtains related data through a Radio Frequency signal. When an Agilent N6705B direct current power supply analyzer is used for measuring a commonly used RFID chip, the average current is 368uA and the peak value is 21mA in the standby mode. In transmit mode 1(1 pulse/sec), average current 410uA, start pulse: pulse width 0.5mS, average current 11mA, peak current 22mA, transmit pulse: pulse width 0.33mS, average current 83mA, peak current 268 mA. In the emission mode 2(25 pulses/sec), the average power consumption current was 7.7mA, the average current was 6.7mA, and the peak value was 289 mA. The normal working current of the lift sensor is generally 5mA, and the standby current is 1 mA. As can be seen from the data, the wireless radio frequency signal sent by the master station 10 can completely supply power to the lift sensor. In addition, the working distance of the RFID, the frequency of 433.92MHz, can reach 1 kilometer far; the frequency is 915MHz, and the far frequency can reach more than 25 meters; the frequency of 2.4GHz can reach 200 m, and the device can be completely used in construction occasions
