Description

Technical Field

[0001] This invention belongs to the field of personnel protection in tunneling faces, and specifically relates to a method and device for sharing the status of personnel in tunneling faces based on information broadcasting. Background Technology

[0002] Because mobile equipment at the tunneling face needs to operate alternately and cyclically during production, dust concentrations are high, and blind spots exist during equipment movement, increasing the risk of personnel crushing accidents. To address this, some mines have installed personnel approach protection systems on mobile equipment at the tunneling face for personnel protection. However, underground tunneling processes are complex, sometimes requiring a single person to perform multiple tasks, and sometimes requiring workers to operate equipment close to other machines. Existing personnel approach protection systems cannot meet the demands of current complex processes, and multiple machines cannot effectively coordinate, severely hindering coal mining while simultaneously pursuing safe production.

[0003] Currently, the personnel approach protection system at underground tunneling faces does not consider enabling single-person multi-position operations through personnel information sharing. Summary of the Invention

[0004] In order to solve at least one of the above-mentioned technical problems in the prior art, the present invention provides a method and apparatus for sharing the status of personnel at a tunneling face based on information broadcasting.

[0005] This invention is implemented using the following technical solution: a method for sharing personnel status at a tunneling face based on information broadcasting, comprising the following steps:

[0006] S1: Configure the parameters of the processing terminal on the mobile device at the tunneling face and perform a power-on self-test;

[0007] S2: Workers at the working face carry identification cards into the tunneling face and establish communication with the processing terminal of the mobile equipment. The processing terminal broadcasts the identification card information and calculates the distance.

[0008] S3: Based on the distance between the identification card and the processing terminal, and the information broadcast from the identification card, the processing terminal controls the mobile device to perform alarm, shutdown, or maintain the status quo operations.

[0009] Preferably, the parameters of the processing terminal include operator identification card information, alarm protection area, shutdown protection area, work area or off-duty protection area.

[0010] Preferably, the method for processing the broadcast of identification card information in the terminal is as follows:

[0011] T1: The mobile device identifies whether the operator carrying the current identification card is a staff member of this device based on the parameter settings;

[0012] T2: If the user is not a staff member of this equipment, no identification card information will be broadcast in the alarm protection area or shutdown protection area of ​​the equipment, and the processing terminal will only perform the ranging function.

[0013] If a staff member of this equipment enters the equipment's working area, the ranging module and communication broadcast module of the processing terminal on the equipment will work together. The communication broadcast module will broadcast the information of the identification card carried by the staff member. If the working area of ​​this equipment overlaps with the alarm protection area, shutdown protection area, or off-duty shutdown area of ​​another equipment, the processing terminal of the other equipment will receive the broadcast identification card information in the overlapping area and temporarily evade the staff member by shutting down the equipment. No alarm or shutdown will be triggered in the overlapping area.

[0014] Preferably, when the personnel cross from the work area to the off-duty shutdown area, the equipment is triggered to stop, and the processing terminal only performs the ranging function and does not broadcast the identification card information.

[0015] Preferably, the distance between the identification card and the personnel approaching the processing terminal is calculated using a multi-range distance measurement method.

[0016] Preferably, the operator identification card information includes equipment personnel, non-equipment personnel, and the number of identification cards; the self-test includes self-testing of the processing terminal, control components, and parameter settings.

[0017] Preferably, it includes an identification card and a processing terminal; wherein the identification card is used to carry relevant information of the operator; the processing terminal includes a UWB ranging module and a communication broadcasting module, used to calculate the distance between the identification card and the processing terminal, broadcast the information of the identification card, and control the mobile device to perform alarm, shutdown or maintain status operations.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention can effectively protect personnel from approaching mobile equipment underground while ensuring normal production processes; it can effectively solve the problem of one person holding multiple positions, thus reducing manpower, increasing efficiency, and improving safety supervision.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] It should be noted that the structures, proportions, sizes, etc., shown in the accompanying drawings of this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented. Therefore, they have no substantial technical significance.

It should be noted that in this specification, relational terms such as "first" and "second" are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0031] This invention provides an embodiment:

[0032] A method for sharing personnel status at a tunneling face based on information broadcasting includes the following steps:

[0033] S1: Configure the parameters of the processing terminal on the mobile device at the tunneling face and perform a power-on self-test;

[0034] S2: Workers at the working face carry identification cards into the tunneling face and establish communication with the processing terminal of the mobile equipment. The processing terminal broadcasts the identification card information and calculates the distance.

[0035] S3: Based on the distance between the identification card and the processing terminal, and the information broadcast from the identification card, the processing terminal controls the mobile device to perform alarm, shutdown, or maintain the status quo operations.

[0036] The parameters of the processing terminal include operator identification card information, alarm protection zone, shutdown protection zone, and work area or off-duty protection zone. Operator identification card information includes whether the operator is a staff member working on the equipment or not, and the number of identification cards. Self-testing includes checks on the processing terminal, control components, and parameter settings. The distance from the identification card to the operator approaching the processing terminal is calculated using a multi-range distance measurement method.

[0037] The method for processing the broadcast of identification card information in the terminal is as follows:

[0038] T1: The mobile device identifies whether the operator carrying the current identification card is a staff member of this device based on the parameter settings;

[0039] T2: If the user is not a staff member of this equipment, no identification card information will be broadcast in the alarm protection area or shutdown protection area of ​​the equipment, and the processing terminal will only perform the ranging function.

[0040] If a staff member of this equipment enters the equipment's working area, the ranging module and communication broadcast module of the processing terminal on the equipment will work together. The communication broadcast module will broadcast the information of the identification card carried by the staff member. If the working area of ​​this equipment overlaps with the alarm protection area, shutdown protection area, or off-duty shutdown area of ​​another equipment, the processing terminal of the other equipment will receive the broadcast identification card information in the overlapping area and temporarily evade the staff member by shutting down the equipment. No alarm or shutdown will be triggered in the overlapping area.

[0041] When the personnel cross from the work area to the off-duty shutdown area, the equipment is triggered to stop. The processing terminal will only perform the ranging function and will not broadcast the identification card information.

[0042] When information sharing is conducted via broadcasting, the following problems can be solved (but not only the following problems):

[0043] like Figure 5 As shown, (1) when a staff member operates equipment A and approaches equipment B (this staff member is an employee of equipment A and an outsider of equipment B), information sharing is performed:

[0044] When a worker carrying an identification card operates equipment A within the work area of ​​equipment A, as equipment A approaches equipment B, the worker's identification card information is broadcast by equipment A to equipment B. Upon receiving and analyzing this broadcast, equipment B can determine that the worker is an employee of equipment A and is within a safe zone. Therefore, the worker will not trigger an alarm or shutdown on equipment B, thus ensuring the safe approach of the equipment and preventing disruption to normal underground production. (Without this information sharing, if the worker drives equipment A into equipment B's alarm or shutdown zone, equipment A will be triggered, preventing the approach operation.)

[0045] 2) One person holding multiple positions:

[0046] like Figure 6 As shown, there is a situation underground where one person operates multiple pieces of equipment. In this case, the person needs to be designated as a worker for multiple pieces of equipment. However, when the person is driving equipment and simultaneously approaches multiple pieces of equipment (and is also a worker for these pieces of equipment), there will be a situation where the person is in the working area of ​​equipment A while being in the off-duty shutdown area of ​​other equipment, making it impossible for the equipment to follow each other. When the person enters the working area of ​​equipment A, the person's identification card information is broadcast to other equipment. The other equipment, through parsing, receives the information that the person is currently operating equipment A and temporarily avoids the person in the off-duty shutdown area, thereby realizing one person working in multiple positions.

[0047] When personnel working on equipment A and equipment B are in the work area of ​​equipment A and the off-duty protection area of ​​equipment B, the processing terminal of equipment A informs equipment B via broadcast: the personnel working on equipment A and equipment B are currently in the work area of ​​equipment A and are operating equipment A. Equipment B should be temporarily shut down to avoid this situation. Equipment B can temporarily pass through or follow the operation. At the same time, the personnel can also leave equipment A and operate equipment B in the same way, thus realizing the role of one person in multiple positions.

[0048] The present invention also provides a personnel status sharing device for tunneling faces based on information broadcasting, including an identification card and a processing terminal; wherein the identification card is used to carry relevant information of the workers; the processing terminal includes a UWB ranging module and a communication broadcasting module, used to calculate the distance between the identification card and the processing terminal, broadcast the information of the identification card, and control the mobile device to perform alarm, shutdown or maintain status operations.

[0049] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
