Weighting and temperature/humidity monitoring ground mat for piled object based on NB-IOT and monitoring method

Abstract

A monitoring ground mat for a piled object based on NB-IOT (Narrow Band Internet of Things) wireless Internet of things communication technology comprises a ground mat, a splicing unit and a ground mat host, wherein the splicing unit comprises a pressure conversion module, a temperature sampling module, a humidity sampling module and a data transmission module, and the ground mat host comprises apower supply module, a power supply management module, a CPU (Central Processing Unit) calculation module and an NB-IOT communication module; the pressure conversion module consists of a plurality ofdistributed film type pressure sensors, and the output of the pressure sensor is connected with a filtering and amplifying circuit and is used for transmitting electric signals to the CPU calculationmodule after the electric signals are amplified and filtered; the pressure sensor is also used for sensing a heavy object placed on an electronic scale and converting gravity into a voltage analog signal; the temperature sampling module is internally provided with a temperature sensitive chip or a sensor and is used for acquiring original data and transmitting the original data to the CPU calculation module; an MCU is used for receiving original data transmitted by a temperature acquisition chip, transmitting the original data to the NB-IOT communication module, therefore, the monitoring ground mat is used for acquiring the real-time temperature of the piled object, and the number of the temperature sampling modules can be set according to actual requirements.

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...

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;
