Description

Technical Field

[0001] The present invention belongs to the field of personnel protection in tunneling working faces, and in particular relates to a personnel status sharing method and device for tunneling working faces based on identification card assignment. Background Art

[0002] Because mobile equipment at the tunneling face must cycle through operations, dust concentrations are high during production, and there are visual blind spots during equipment movement, making accidents prone to crushing and injury. To address this, some mines install proximity protection systems on mobile equipment at the tunneling face to protect personnel. However, the complex underground tunneling process sometimes requires a single person to perform multiple tasks, and sometimes requires workers to operate equipment close to one another. Existing proximity protection systems cannot meet the current complex process requirements, and multiple machines cannot effectively interact with each other, severely restricting coal mining while ensuring safe production.

[0003] The current personnel access protection system for underground excavation working faces does not consider the realization of single-person multi-post operation through personnel information sharing. Summary of the Invention

[0004] In order to solve at least one of the above-mentioned technical problems existing in the prior art, the present invention provides a method and device for sharing the status of personnel in an excavation working face based on identification card assignment.

[0005] The present invention is implemented by the following technical solution: a method for sharing personnel status of an excavation working face based on identification card assignment, comprising the following steps:

[0006] S1: Configure the parameters of the processing terminal on the mobile device at the excavation working face and power on the terminal for self-test;

[0007] S2: The face operator carries an identification card into the excavation face and establishes communication with the processing terminal of the mobile device. The processing terminal assigns a value to the identification card and calculates the distance.

[0008] S3: Based on the distance between the identification card and the processing terminal and the value of the flag bit of the identification card, the processing terminal controls the mobile device to execute an alarm, shut down, or maintain the status quo.

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

[0010] Preferably, the method for the processing terminal to assign a value to the flag bit of the identification card is:

[0011] T1: The mobile device identifies whether the operator carrying the current identification card is the operator of this device according to the parameter settings;

[0012] T2: If the person is not a staff member of the equipment, the flag bit of the identification card of the person is set to 0, and the equipment alarm or shutdown is triggered in the alarm protection area or shutdown protection area of ​​the equipment;

[0013] If a staff member of this equipment enters the working area of ​​the equipment, the flag bit of the personnel's identification card will be assigned a value of 1, and the flag bit will be followed by the equipment serial number, and the equipment alarm or shutdown will not be triggered; if the working area of ​​the equipment overlaps with the alarm protection area or shutdown protection area of ​​another equipment, the flag bit of the personnel's identification card and the equipment serial number will not be changed in the overlapping area.

[0014] Preferably, when the personnel crosses from the working area to the off-post shutdown area, the equipment is triggered to shut down; and it is determined whether the off-post shutdown area overlaps with the working area of ​​another equipment. If not, the identification card carried by the personnel is assigned a value of 0; if so, within the overlapping area, the processing terminal of the above-mentioned other equipment determines whether the operator carrying the current identification card is also a staff member of the above-mentioned other equipment; if so, the identification card carried by the personnel is assigned a value of 1, and the flag bit is followed by the serial number of the above-mentioned other equipment; if not, the flag bit of the personnel's identification card is assigned a value of 0, triggering the above-mentioned other equipment to alarm or shut down.

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

[0016] Preferably, the operator identification card information includes equipment staff, non-equipment staff, and the number of identification cards; the self-inspection includes the self-inspection of the processing terminal, control components, and parameter setting values.

[0017] The present invention also provides a tunneling working face personnel status sharing device based on identification card assignment, which is used to implement a tunneling working face personnel status sharing method based on identification card assignment, including an identification card and a processing terminal; wherein the identification card is used to carry relevant information of the working personnel; the processing terminal is used to calculate the distance between the identification card and the processing terminal, assign a value to the flag bit of the identification card, and control the mobile device to perform alarm, shutdown or maintain status operations.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention can effectively ensure the protection of personnel approaching mobile equipment underground while ensuring the normal production process; it can effectively solve the problem that one person cannot perform multiple posts, and achieve the goal of reducing manpower, increasing efficiency and ensuring safety supervision.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention are clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other implementations derived by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts are within the scope of protection of the present invention.

Therefore, they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size should fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose that can be achieved by the present invention. 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] The present invention provides an embodiment:

[0032] like Figures 1 to 7 As shown, a method for sharing personnel status at an excavation working face based on identification card assignment includes the following steps:

[0033] S1: Configure the parameters of the processing terminal on the mobile device at the tunneling face and power on for self-testing. The self-test includes self-testing of the processing terminal, control components, and parameter settings.

[0034] S2: The face operator carries an identification card into the excavation face and establishes communication with the processing terminal of the mobile device. The processing terminal assigns a value to the identification card and calculates the distance.

[0035] S3: Based on the distance between the identification card and the processing terminal and the value of the identification card's flag, the processing terminal controls the mobile device to execute an alarm, shut down, or maintain the current status. The distance between the identification card and the person approaching the processing terminal is calculated using a multi-range ranging method.

[0036] The parameters of the processing terminal include operator identification card information, alarm protection area, shutdown protection area, working area or off-post protection area. The operator identification card information includes equipment staff, non-equipment staff, and the number of identification cards;

[0037] The method for the processing terminal to assign a value to the flag bit of the identification card is:

[0038] T1: The mobile device identifies whether the operator carrying the current identification card is the operator of this device according to the parameter settings;

[0039] T2: If the person is not a staff member of the equipment, the flag bit of the identification card of the person is set to 0, and the equipment alarm or shutdown is triggered in the alarm protection area or shutdown protection area of ​​the equipment;

[0040] If a staff member of this equipment enters the working area of ​​the equipment, the flag bit of the personnel's identification card will be assigned a value of 1, and the flag bit will be followed by the equipment serial number, and the equipment alarm or shutdown will not be triggered; the personnel can operate the equipment, the control components will not operate, the equipment will not shut down, and the alarm will not sound; when the underground workers leave the excavation working face, move away from the mobile equipment to a certain distance, or the identification card is out of power, the identification card will not be able to establish communication with the processing terminal, making the personnel unable to be protected by the personnel proximity protection system.

[0041] If the working area of ​​the equipment overlaps with the warning protection area or shutdown protection area of ​​another equipment, the identification card flag of the person and the subsequent equipment serial number will not be changed in the overlapping area.

[0042] When the person crosses from the work area to the off-post shutdown area, the equipment is triggered to shut down; and it is determined whether the off-post shutdown area overlaps with the working area of ​​another device. If not, the identification card carried by the person is assigned a value of 0, indicating that the person has left his or her work post and there are safety hazards in the area; if so, in the overlapping area, the processing terminal of the other device determines whether the operator carrying the current identification card is also a staff member of the other device; if so, the identification card carried by the person is assigned a value of 1, and the flag bit is followed by the serial number of the other device; if not, the flag bit of the person's identification card is assigned a value of 0, triggering the alarm or shutdown of the other device.

[0043] Specifically,

[0044] (1) When a worker operating device A approaches device B (the worker is a worker of device A and an outsider of device B), information sharing is performed:

[0045] like Figure 5 As shown, when a worker carries an identification card and drives device A in the working area of ​​device A, the worker identification card is assigned a value of 1A. When the worker drives device A close to device B, the identification card can also communicate with the personnel approach processing terminal of device B. At the same time, the processing terminal of device B reads the flag bit of the worker identification card. When the flag bit is read as 1A, it indicates that the worker is a worker of device A and is in a safe area. The worker will not trigger device B to alarm or shut down. In this way, while ensuring the safety of the personnel, the normal approach between the devices is completed without affecting normal production underground. (If information sharing is not carried out, when the worker drives device A into the alarm area or shutdown area of ​​device B, it will trigger device A to alarm and shut down, and the approach work will not be completed.)

[0046] (2) One person holds multiple posts:

[0047] There are situations where one person operates multiple devices underground. In this case, the person needs to be set as a staff member of multiple devices. However, multiple devices can be close at the same time, and any device can assign 0 or 1 to the person's identification card flag, which will cause confusion and instability in the identification card assignment. Therefore, the flag bit is added to the device serial number. When the person first enters the working area of ​​device A, the flag bit is set to 1A. When devices B and C read the flag bit of the staff member's identification card as 1A, it indicates that the person is a staff member, and the alarm and shutdown of devices B and C are not triggered. At the same time, devices B and C have no right to reassign the person's flag bit. Until the person leaves the working area of ​​device A and enters the working area of ​​device B or device C for the first time, the flag bit of the person's identification card can be reassigned to 1B or 1C.

[0048] See Figure 6 When a worker on equipment A and B is in the work area of ​​equipment A, if the worker is assigned a value of 1 by equipment A and a value of 0 by equipment B, this will cause confusion and disrupt the normal process flow. The worker is in the work area of ​​equipment A and is assigned a value of 1A. When equipment B recognizes the worker's flag bit serial number, it does not change the worker's flag bit, allowing the process to proceed normally.

[0049] The present invention also provides a tunneling working face personnel status sharing device based on identification card assignment, which is used to implement a tunneling working face personnel status sharing method based on identification card assignment, including an identification card and a processing terminal; wherein the identification card is used to carry relevant information of the working personnel; the processing terminal is used to calculate the distance between the identification card and the processing terminal, assign a value to the flag bit of the identification card, and control the mobile device to perform alarm, shutdown or maintain status operations.

[0050] The foregoing description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be readily conceived by a person skilled in the art within the technical scope disclosed herein should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
