[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] Embodiment 1 of the present utility model discloses a belt conveyor electric control device based on a mining system, such as Figure 1 As shown, it includes: host computer, PLC control cabinet and underlying sensing equipment.

[0024] The host computer can realize the centralized monitoring, management, storage and query functions of each subsystem, enhance the correlation between modules, and perform the configuration, upgrade and maintenance of the control system. At the same time, the collected data information is stored in the local database to prevent data loss or damage.

[0025] The PLC control cabinet, including: main belt shaft control cabinet, main transport part 1 control cabinet, main transport part 2 control cabinet, is used to upload equipment operation information and execute relevant functional instructions issued by the host computer.

[0026] The underlying sensing devices, including motors, belt cameras, smoke sensors, coal pile sensors, and deviation sensors, obtain equipment operating status and on-site environmental data information, and upload data through the 5G network.

[0027] The underlying sensing device uses a 5G base station to transmit the collected data to the host computer in real time through the PLC control cabinet. The host computer issues control instructions through the PLC control cabinet based on the collected data.

[0028] It also includes: a voice announcer, which is used for voice alarms and call management, and sends important information to operators or other personnel when needed. It is equipped with a battery inside to ensure that the power supply along the line is interrupted and the voice announcer can continue to work; the voice announcer and the underlying sensing equipment both have built-in 5G communication modules, which are connected to the PLC control cabinet through a 5G base station.

[0029] The PLC control cabinet uses a Siemens S7-1200 PLC controller, which is connected to the 5G wireless gateway. The external signal is connected to the PLC controller through the conversion module integrated inside the PLC control cabinet, realizing the "one-button start and stop" control of the equipment and completing the signal interaction and interlocking control between the devices.

[0030] The motor is belt driven by dual motor soft start mode and is equipped with a soft start hydraulic station motor start switch for remote and local control.

[0031] The belt camera adopts flameproof intrinsically safe camera, which is used to transmit on-site monitoring images in real time. It has all-weather, multi-angle, high-definition monitoring capabilities, realizes efficient data transmission and remote monitoring functions, and ensures the smooth progress of the conveying process.

[0032] The smoke sensor uses a gas-sensitive probe with a switch output to detect smoke generated by the friction between the roller and the belt. When the smoke concentration is greater than the set value, the open light contact is closed and the smoke alarm is activated. It can monitor the on-site smoke concentration in real time and accurately, and transmit it to the ground host computer using a wireless base station to prevent safety accidents such as fire.

[0033] The coal pile sensor is hung above the coal bunker and the head of the belt conveyor, 1.5-2 meters away from the coal bunker opening. It has intrinsic safety performance and is used to detect the coal level to avoid blockage or overflow. The normal coal level does not touch the sensor touch rod. When the coal level touches the touch rod and pushes it away from the upper limit angle, the belt conveyor stops and an alarm signal is issued.

[0034] The deviation sensor adopts an intrinsically safe design and is connected to a control device with intrinsically safe terminal output. It is installed at the head, body and tail of the belt conveyor to detect belt deviation. When the belt deviates, the direction rod of the sensor is touched to make it move, and the switch signal is output to the control system to alarm and stop the conveyor, thereby preventing the material on the conveyor belt from deviating from the predetermined path, causing material loss or equipment damage.

[0035] Working principle: The motor, belt camera, smoke sensor, coal pile sensor and deviation sensor use 5G base station to transmit the collected data to the host computer in real time through the PLC control cabinet. The host computer issues control instructions and alarm instructions through the PLC control cabinet based on the collected data.

[0036] The embodiment of the utility model discloses an electric control device for a belt conveyor based on a mine Hong system. The utility model is based on a 5G base station and uses a unified communication protocol to transmit the data collected by the motor, belt camera, smoke sensor, coal pile sensor and deviation sensor deployed at various key positions of the belt conveyor to the host computer through a PLC control cabinet. The host computer issues control instructions and alarm instructions through the PLC control cabinet based on the collected data, which not only realizes the ground centralized control and real-time automatic monitoring of the underground belt conveyor, including: smoke monitoring, coal pile monitoring and deviation monitoring, but also realizes stable and reliable transmission based on a unified communication protocol between various devices, effectively enhancing the safety and reliability of the belt conveyor, improving the overall automation management level of the mine belt conveyor, and achieving the purpose of reducing staff and increasing efficiency.
