A floor mat and monitoring method based on nb-iot for weighing and monitoring temperature and humidity of piles

Abstract

A monitoring floor mat based on NB-IOT wireless Internet of Things communication technology, including a floor mat, a splicing unit and a floor mat host, and the splicing unit includes a pressure conversion module, a temperature sampling module, a humidity sampling module, and a data transmission module , the ground mat host includes a power supply module, a power management module, a CPU computing module, and a NB-IOT communication module; the pressure conversion module is a plurality of distributed thin-film pressure sensors, and the output of the pressure sensor is connected to a filter and an amplification circuit for converting The electrical signal is transmitted to the CPU calculation module after being amplified and filtered; the pressure sensor is also used to sense the weight placed on the electronic scale and convert the gravity into a voltage analog signal; the temperature sampling module is equipped with a temperature sensitive chip or sensor, Collect raw data and transmit it to the CPU computing module; the MCU receives the raw data transmitted by the temperature acquisition chip and transmits it to the NB-IOT communication module for collecting real-time temperature of piles. The number of temperature sampling modules can be set according to actual needs.

Description

technical field [0001] The invention relates to the technical field of material management, specifically an intelligent material monitoring and management technology based on NB-IOT Internet of Things technology + pressure sensor technology and temperature and humidity sensor technology. Background technique [0002] New types of IoT connectivity are Industrial Internet of Things (IIoT) solutions that require Low Power Wide Area (LPWA) technologies to provide efficient connectivity, ubiquitous coverage and competitive payment-for-service models for low-bandwidth solutions. IIoT applications may also require seamless coverage in remote environments, where an always-on connection consumes power and shortens the life of a solution that can operate for a decade or more in the field . Narrowband Internet of Things (NB-IoT) technology is a promising solution. [0003] Narrowband Internet of Things (NB-IoT) is a new wireless technology standardized by 3GPP in 2016. It is rapidly...

AI Technical Summary

Problems solved by technology

[0012] 1. The stacked objects occupy a large area, and as the items are stacked, the occupied area also increases;

[0013] 2. Under normal circumstances, the manager has registration and records for the incoming and outgoing materials, but there is no monitoring and verification of the consistency of the incoming and outgoing materials for the existing general warehouse of materials;

[0014] 3. The places where the piles are generally bad, and it is difficult to supply power outdoors. Some piles, such as: coal, are not easy to power on to avoid fire monitoring equipment;

[0015] 4. The places where the piles are usually placed outdoors bring certain difficulties to network construction and data transmission;

[0016] 5. Also because the places where the piles are mentioned are generally outdoors, it brings great challenges to the security work;
