Beidou synchronous high-speed real-time wireless sensor acquisition system and method based on 4G/5G

Abstract

The invention discloses a Beidou synchronous high-speed real-time wireless sensor acquisition system and method based on 4G / 5G. A sensor sends the sensor detection information to an FPGA chipset, a Beidou timing module sends the timing information to a power supply / communication composite module through a trigger / power supply module, and the trigger / power supply module also sends the trigger information to the power supply / communication composite module; the power supply / communication composite module supplies power to the FPGA chipset, separates out the timing information and trigger information and sends the timing information and the trigger information to the FPGA chipset, and a 4G / 5G communication module is used for reporting the trigger data to a cloud in real time in a production brief report manner, and reporting the over-limit data of the detection information to the cloud in the production brief report manner. According to the present invention, the timing and independent operation of a plurality of sensors can be guaranteed, a large number of cables do not need to be laid, the system maintenance is easy, and the requirements for sensor data acquisition synchronism and high precision of the emergency tasks are met.

Description

technical field [0001] The invention belongs to the technical field of wireless sensors, and relates to a Beidou synchronous high-speed real-time wireless sensor acquisition system and method based on 4G / 5G. Background technique [0002] The wireless sensors currently used in the domestic market are all based on ZigBee, lora, FM, 2G, NB-IOT, etc. These sensors can only achieve static collection and transmission of small data and low power consumption, and the synchronization, timing, and data volume cannot meet the requirements. High-speed, synchronous, real-time, synchronous preprocessing, acquisition and transmission requirements of large amounts of data such as bridges, structures, and geological disasters in the future. [0003] At present, high-speed dynamic data acquisition schemes all use optical fiber or distributed sensors plus high-speed data acquisition terminals to realize high-speed dynamic data collection and processing. In this way, industrial computers, UPS,...

AI Technical Summary

Problems solved by technology

In this way, industrial computers, UPS, data acquisition terminals, networks, heat preservation cabinets, a large number of cables, a large number of cable protection tubes, etc. need to be deployed on site. The dense network and large interference are also not conducive to ultra-high-precision acquisition.

[0004] This kind of high-speed dynamic data acquisition scheme has a long installation period, cannot be deployed quickly and urgently for rescue tasks, etc., and the deployment cost is relatively high

It is not easy to maintain in the later period, and cannot be quickly diagnosed and replaced. Especially compared with railway bridges, the time for skylights is relatively precious, and it needs to be installed quickly and can quickly solve a certain point of failure.

And each parameter cannot be collected synchronously at the same time, such as stress, temperature, deflection, vibration, cable force, acceleration, amplitude, displacement, crack and other parameters, the timing accuracy of data collection cannot be guaranteed
