Technical Field

[0001] The utility model relates to the technical field of powder silo material level monitoring, and in particular to a material level door LED display system based on the MQTT transmission protocol. Background Art

[0002] Powder silo level monitoring is a device that monitors the position of powder materials in the powder silo.

This is not conducive to monitoring the material level in the powder silo. In addition, the monitoring data cannot be uploaded to the cloud platform for unified management, and information sharing is impossible. Material tags need to be manually modified, which increases labor costs. Summary of the Invention

It reduces the wiring complexity through wired connection, realizes 24-hour monitoring of multiple powder silos, and uploads data to mobile terminals and WEB terminals in real time to realize data sharing and real-time updates, significantly improves monitoring efficiency, and reduces management costs.

[0005] To achieve the above-mentioned purpose and other related purposes, the utility model provides a material level door LED display system based on the MQTT transmission protocol, including a material level data acquisition module, an MQTT server, a mobile terminal, a WEB terminal, and a material level data acquisition controller. The material level data acquisition controller is connected to multiple material level data acquisition modules, and the material level data acquisition controller is connected to the MQTT server through the MQTT transmission network. The MQTT server is respectively connected to the mobile terminal, the WEB terminal, and multiple LED control boxes.

[0006] In one embodiment, the material level data acquisition controller is connected to the material level data acquisition module via a wired connection.

[0007] In one embodiment, the material level data acquisition module includes a single-chip microcomputer module and a display module, a storage module, a power module, a communication module, and a sensor acquisition module connected to the single-chip microcomputer module. The sensor acquisition module is connected to the patch pressure sensor.

[0008] In one embodiment, the display module uses a 7-segment digital tube display.

[0009] In one embodiment, the material level data acquisition controller includes an AC-DC module and an MCGS touch screen connected to the AC-DC module, and the MCGS touch screen is connected to the communication module and the MQTT server respectively.

[0010] In one embodiment, the LED control box includes an LED display screen and an LED control card. The LED display screen is connected to the LED control card and a 5V power supply respectively. The 5V power supply is connected to the LED control card. The LED control card is connected to the MCGS touch screen.

[0011] Compared with the existing technology, the material level door LED display system based on the MQTT transmission protocol provided by the utility model connects the material level data acquisition controller and multiple material level data acquisition modules in a wired manner, which reduces the wiring complexity and reduces the management and application costs.

[0012] The material level data acquisition controller can connect multiple material level data acquisition modules to achieve 24-hour uninterrupted monitoring of multiple powder silos and multiple powder materials, with relatively low investment cost;
