Technical Field

[0001] The utility model relates to the field of industrial process control and safety protection, in particular to an early warning system for personnel entering a key area at a chute discharge port. Background Art

[0002] Mining chutes are currently widely used in mining, primarily to connect different stages and serve as vertical or inclined conveyance channels for ore, improving transportation efficiency and saving costs. By utilizing the ore's own weight for vertical or inclined conveyance, chutes avoid frequent vehicle transport, significantly improving ore transportation efficiency. In addition to serving as ore conveyance channels, chutes can also be used for pedestrian access, material transportation, ventilation, backfilling operations, and prospecting, demonstrating their versatility in mine shaft construction.

[0003] However, the working environment in the chute is poor and is not suitable for manual inspection on site; and there is a risk of silo collapse at the chute outlet, and the potential risk of silo collapse will increase when personnel enter the area. The existing technology has made relevant improvements, but the following defects still exist: First, there are no warning alarm devices for personnel entering key areas on site and in the control room, and the on-site equipment protection devices are not perfect; second, once a blockage occurs in the chute, or the chute breaking system equipment fails, timely warning cannot be given, and the chute breaking system equipment cannot be stopped in time, and the idling of the equipment causes a waste of resources; third, the poor real-time monitoring and measurement results in delayed warning messages. If the risks cannot be dealt with in time, personnel or production safety accidents may occur. Summary of the Invention

[0022] Example 1

[0023] like Figure 1-2 As shown, an early warning system for personnel entering a critical area at a chute discharge port includes:

[0024] The multi-level distance measurement module is connected to the human body sensing module and the MCGS (Monitor and Control Generated System) control module to monitor the distance between people and preset key areas in real time;

[0025] The human body sensing module is connected to the MCGS control module to monitor in real time whether there are people or other objects entering the preset key areas of the chute;

[0026] MCGS control module is used to process and analyze the data received from the multi-level ranging module and the human body sensing module, and send corresponding control signals;

[0027] The multi-level early warning module is connected to the MCGS control module and is used to receive corresponding control signals and perform corresponding early warning operations.

[0028] like Figure 1 As shown, this embodiment uses a multi-level distance measurement module to monitor the distance between personnel and preset key areas in real time, and a human body sensing module to monitor whether there are personnel or other objects entering the preset key areas of the chute. The MCGS control module processes and analyzes the data received from the multi-level distance measurement module and the human body sensing module, and sends corresponding control signals to the multi-level early warning module, thereby realizing corresponding early warning operations. In order to prevent personnel from entering the key area at the chute discharge port, the collaborative work of multi-level distance measurement, human body sensing, MCGS control and multi-level early warning modules is adopted to realize real-time monitoring and early warning of personnel entering dangerous areas, improve the safety of the operating area, reduce the probability of accidents, greatly improve the early warning efficiency, and provide a strong safety guarantee for chute operations.

[0029] In the preferred solution, the setting of the preset key area is specifically as follows: taking the preset reference point as the base point, presetting the first distance threshold and the second distance threshold, and performing multi-level division according to the distance size; wherein the first distance threshold is greater than the second distance threshold.

[0030] In this embodiment, the preset reference point is the starting point for distance measurement. In the scenario of the chute outlet, the reference point can be selected at the edge of the outlet, the boundary of the safety area or other representative locations.

[0031] In this embodiment, the edge of the discharge port is used as the preset reference point for illustration. Considering that personnel have enough time to react and evacuate from this point to the dangerous area, the first distance threshold is set to 10 meters and the second distance threshold is set to 5 meters. The distance threshold can be adaptively changed according to actual application.

[0032] According to the distance size, the key areas are divided into multiple levels: the area between the reference point and the first distance threshold can be defined as the safe state area, the area between the first distance threshold and the second distance threshold is the normal warning state area, and the area within the second distance threshold is the emergency warning state area.

[0033] In a preferred embodiment, the multi-level distance measurement module includes an infrared electronic fence or a distance measurement sensor.

[0034] The multi-level ranging module can realize accurate monitoring and early warning of personnel approaching dangerous areas, thereby improving the safety of the working area.

[0035] Furthermore, infrared electronic fences and distance measuring sensors are used in combination to achieve a multi-level early warning function: in safe areas, infrared electronic fences are used to monitor whether people have crossed the boundary; in other areas, distance measuring sensors are used to accurately measure the distance between people and key areas.

[0036] The preferred solution further includes a switching optical terminal for transmitting data;

[0037] MCGS control module includes relay module and MCGS touch screen;

[0038] The human body sensing module transmits data to the relay module and MCGS touch screen through the switch optical terminal. The MCGS touch screen uses the relay module to process and analyze the collected data.

[0039] In this embodiment, the switching optical terminal ensures stable and reliable data transmission and is a key component for achieving communication between various parts of the early warning system.

[0040] The relay module includes multiple relays, each of which switches its output state according to the received signal state, thereby controlling the corresponding early warning equipment, such as sound alarms and light flashers.

[0041] The MCGS touch screen is used to display real-time information of people approaching key areas, including distance, warning level, etc.; and the MCGS touch screen can also be used to set parameters of the warning system, such as distance threshold, warning time, etc.

[0042] The various modules work together to achieve real-time monitoring and early warning of people approaching key areas, ensuring the stability, accuracy and intuitiveness of data transmission, and improving the reliability and practicality of the early warning system.

[0043] The preferred solution also includes an HMI (Human-Machine Interface) monitoring module connected to the MCGS control module, which is used to monitor the status of preset key areas in real time on-site and remotely, and to manually control the equipment in the preset key areas and record relevant data.

[0044] During operation, if someone accidentally enters a critical area, the MCGS control module will send relevant emergency information to the HMI monitoring module and issue an alarm signal through the sound, light and voice alarm device. The HMI monitoring module will also display the warning information, the equipment's shutdown status and the reason for the shutdown in real time.

[0045] In this embodiment, the HMI monitoring module is used to realize remote or local control of equipment in key areas and data recording and analysis, thereby improving the monitoring capability, response speed and security of the system.

[0046] In a preferred embodiment, the multi-level warning module includes an audible and visual alarm device and an emergency braking device.

[0047] Furthermore, the multi-level warning module receives corresponding control signals and performs corresponding warning operations. Specifically, the MCGS control module makes a judgment based on the input signal of the relay module. If the current distance of the person or other object monitored by the human body sensing module and the current distance monitored by the multi-level ranging module is greater than the first distance threshold, it is a safe state.

[0048] If the current distance is less than the first distance threshold and greater than the second distance threshold, it is a normal warning state and the sound and light alarm device is activated.

[0049] If the current distance is less than the second distance threshold, it is an emergency warning state, and the sound and light alarm device and the emergency brake device are activated.

[0050] In the preferred embodiment, the emergency braking device includes a ore-discharging machine and a slag-blocking insert. When the emergency braking device is activated, the ore-discharging machine in the chute stops running and the slag-blocking insert is lowered at the same time.

[0051] In this embodiment, the emergency braking device further improves the safety of the system, effectively distinguishes different safety risk levels, and ensures timely response and handling of potential dangers.

[0052] When in use, the multi-level distance measurement module monitors the distance between personnel and the preset key area in real time, the human body sensing module monitors whether there are personnel or other objects entering the preset key area of ​​the chute, the MCGS control module processes and analyzes the data received from the multi-level distance measurement module and the human body sensing module, and the MCGS touch screen uses the relay module to process and analyze the collected data. After receiving the specified signal, it triggers the alarm mechanism and sends alarm information to on-site personnel and the central control operator in the control room through sound and light alarms. If the chute bursts, the material level will rise and the ore discharger will automatically stop, and the slag blocking plate will fall, thereby realizing the corresponding early warning operation.

[0053] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
