Description

Technical Field

[0001] The present invention relates to the technical field of detection of personnel entering / exiting a mine, and in particular to a detection method and system for full-cycle positioning management of underground operations of coal mine personnel. Background Art

[0002] As one of the six major systems for coal mine safety production, the underground personnel positioning system plays an important role in safe production, risk avoidance and disaster relief. With the construction and promotion of smart mines, the implementation of the people-oriented and safe production concepts in coal mines has become increasingly prominent, and the core role of personnel positioning has become increasingly prominent. The personnel positioning system equips each person entering the mine with a positioning card to track and locate underground personnel and limit attendance. However, there are three problems in actual use: (1) After going down the mine, the positioning card is replaced to realize underground shift replacement. (2) Before entering the work face, the positioning card is left outside the work face to avoid overcrowding and evasion of supervision. (3) There are counterfeit positioning cards on the market, which makes the system data unreliable.

[0003] At present, the coal mines that use personnel positioning generally use security gates to detect whether the positioning card is worn correctly, but it still cannot solve the problems of card replacement, retention and counterfeiting in the mine. In addition, the security gate is expensive and has high requirements for installation and access. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a detection method and system for full-cycle positioning management of underground operations of coal mine personnel, which can detect illegal behaviors such as cheating with positioning cards, abnormal card carrying, counterfeit cards, etc.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a detection method for full-cycle positioning management of underground operations of coal mine personnel, comprising the following steps:

[0006] Conduct biometric identification of people entering the mine at the entrance of the underground passage;

[0007] If the recognition is successful, the signal receiving module uses photoelectric detection to detect whether the positioning card is worn on the wrist;

[0008] If yes, the signal receiving module sends an SN verification code to the positioning card;

[0009] The positioning card combines the SN verification code and the positioning card number into an SN code and returns it to the signal receiving module;

[0010] The signal receiving module determines whether the SN code meets the requirements, and if so, allows the person entering the well to pass;

[0011] When the underground personnel want to leave the well, the positioning card sends the SN code to the signal receiving module, and the signal receiving module determines whether the SN code meets the requirements. If so, the personnel are allowed to leave the well.

[0012] Furthermore, the signal receiving module includes: a first receiver A1 and a second receiver A2, and the first receiver A1 and the second receiver A2 are installed on two side walls of the channel C respectively.

[0013] Furthermore, the channel C is provided with an identification preparation area and a detection area, a biometric identification module is installed in the detection area, and the signal receiving module is installed in the detection area.

[0014] Furthermore, when a person enters the identification preparation area, the positioning card enters a quick-send state.

[0015] Furthermore, when a person enters the identification preparation area, the distance between the person and the first receiver A1 is D1, the distance between the person and the second receiver A2 is D2, and the width of the channel C is D ref , when D1<D ref And D2<D ref At this time, the person is considered to have entered the detection area and testing begins on the person.

[0016] Furthermore, the positioning card is worn on the wrist of the person using a wristband, and the wristband is fixed with a buckle. When the buckle is buckled, the positioning card can generate an initial SN code. The initial SN code is 16 digits, and the last five digits are the card number of the positioning card.

[0017] Furthermore, when the signal receiving module recognizes that the positioning card is worn on a person's wrist, the signal receiving module sends a randomly encrypted SN verification code to the positioning card. After receiving the randomly encrypted SN verification code, the positioning card combines it with the positioning card number into an SN code; if the wristband of the positioning card has been opened, the positioning card immediately restores the SN code to the initial SN code.

[0018] Furthermore, if the personnel positioning system detects that a positioning card with an initial SN code appears underground, an alert is immediately issued for the positioning card.

[0019] Furthermore, when there are multiple people waiting in the waiting area, the signal receiving module broadcasts and notifies the positioning cards that are more than 3 meters away from the first receiver A1 or the second receiver A2 to enter the slow-sending state; when the waiting person is equal to or less than 3 meters away from the first receiver A1 or the second receiver A2, the positioning card of the person is switched to the fast-sending state.

[0020] The present invention also discloses a detection system for full-cycle positioning management of underground coal mine personnel, which adopts the detection method for full-cycle positioning management of underground coal mine personnel. The detection system comprises:

[0021] A biometric identification module, which is installed in the detection area of ​​channel C and is used to perform biometric identification on people entering / leaving the well;

[0022] A signal receiving module is installed in the detection area of ​​channel C and is used to detect and verify the positioning cards of personnel entering / exiting the well.

[0023] The beneficial effects of the present invention are:

[0024] (1) When the positioning card enters the well for inspection, it obtains a legal SN code, which is unique and automatically reset to the initial SN code when it is tripped. At this time, the personnel positioning system will automatically alarm. When the person leaves the well without legal SN authorization, he cannot pass through the gate and can only be released after the penalty registration. In this way, the problem of replacing positioning cards underground and the problem of retaining positioning cards outside the working face area to avoid over-staffing statistics can be improved.

[0025] (2) The SN code verification mechanism designed by the present invention generates a random SN verification code each time entering the well, and the personnel positioning system directly alarms for illegal SN codes. Those who cannot pass the SN code verification will not be allowed to go down the well. In addition, if the current personnel positioning system wants to eliminate counterfeit positioning cards, the signal receiving module, positioning card, substation, etc. must be upgraded and updated one by one, which is very difficult. With the SN code verification method, the upper computer only needs to change the encryption method of the SN verification code and then resend it to the signal receiving module to complete the replacement of the SN verification code, which can achieve a senseless upgrade.

[0026] (3) By setting the positioning card in the slow-sending state in the wellhead waiting area, the time slot conflict problem of the positioning card waiting at the wellhead is improved. At the same time, the positioning card is switched to the fast-sending state in the identification preparation area to ensure the high timeliness of the data between the positioning card and the signal receiving module.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0033] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] like Figures 1 to 3 As shown, the detection method for full-cycle positioning management of underground coal mine personnel of the present invention includes the following steps: biometric identification of personnel entering the mine at the entrance of the underground passage; if the identification is passed, the signal receiving module uses photoelectric detection to detect whether the positioning card is worn on the wrist; if so, the signal receiving module sends an SN verification code to the positioning card; the positioning card combines the SN verification code and the positioning card number into an SN code and returns it to the signal receiving module; the signal receiving module determines whether the SN code meets the requirements, and if so, the personnel entering the mine are released; when the underground personnel want to leave the mine, the positioning card sends the SN code to the signal receiving module, and the signal receiving module determines whether the SN code meets the requirements, and if so, the personnel leaving the mine are released.

[0036] That is to say, when a person enters the detection area, the biometric module turns on the biometric identification. When it is confirmed that it is the person himself, a message is sent to the signal receiving module. The signal receiving module notifies the positioning card to turn on the photoelectric detection to determine whether the positioning card is worn on the wrist. If so, the positioning card asks the signal receiving module for the SN verification code. The signal receiving module sends a randomly generated SN verification code to the positioning card. After receiving the SN verification code, the positioning card combines the SN verification code with the positioning card number into a unique SN code. Only positioning cards with SN codes that meet the requirements are considered normal. Once the wristband is opened, the positioning card is immediately reset to the initial SN code, which is considered an illegal SN code. The SN code is detected again when leaving the well, and only legal SN codes are allowed to be released. Therefore, the present invention can improve the problems of cheating and counterfeiting of positioning cards.

[0037] It should be noted that the underground passage can be divided into an identification preparation area and a detection area, and the identification preparation area is connected to the waiting area. The underground personnel first wait in the waiting area, and then queue up to enter the identification preparation area and the detection area. After passing the verification in the detection area, they can enter / exit the well.

[0038] Specifically, the signal receiving module includes: a first receiver A1 and a second receiver A2, and the first receiver A1 and the second receiver A2 are respectively installed on the two side walls of channel C. Channel C is provided with an identification preparation area and a detection area, and a biometric identification module is installed in the detection area, and the signal receiving module is installed in the detection area. When the personnel entering or exiting the well enter the identification preparation area, the positioning card enters the quick-send state. When the positioning card is in the quick-send state, the communication efficiency between the signal receiving module and the positioning card is higher. The first receiver A1 and the second receiver A2 are arranged opposite to each other, and the distance between the first receiver A1 and the second receiver A2 is equal to the width D of channel C. ref Basically equal, the first receiver A1 is used as the main receiver, the second receiver A2 is used as the auxiliary receiver, and the receiver is used as the center point. ref Draw a circle with radius D1, and the circular area is the signal sensing range. When a person enters the signal sensing range, the positioning card can transmit signals to the first receiver A1 and the second receiver A2. When a person enters the identification preparation area, let the distance between the person and the first receiver A1 be D1, the distance between the person and the second receiver A2 be D2, and the width of channel C be D ref , when D1<D ref And D2<D ref When the person enters the detection area, it is considered that the person has entered the detection area and the detection of the person begins. In the detection area, the person is subjected to iris or face recognition (i.e. biometric recognition). When the biometric recognition passes, the signal receiving module sends an SN verification code to the positioning card.

[0039] It should be noted that the positioning card is worn on the wrist of the personnel using a wristband, and the wristband is fixed with a buckle. When the buckle is buckled (the circuit will be turned on), the positioning card can generate an initial SN code. When the personnel pass the iris / face recognition, the signal receiving module sends a signal to notify the positioning card. After receiving the signal, the positioning card starts the photoelectric detection sensor to detect whether the positioning card is worn on the wrist. After confirming that it is worn, the positioning card returns the confirmation information to the signal receiving module. Then, the signal receiving module sends a randomly encrypted SN verification code to the positioning card. After receiving the verification code, the positioning card combines it with the positioning card to form a new 16-digit legal SN code (the first eleven digits are the SN verification code, and the last five digits are the positioning card number). Once the positioning card detects that the wristband is untied, it immediately restores the SN code to the initial SN code. If the personnel positioning system detects that a positioning card with an initial SN code appears underground, it will immediately warn the positioning card. This function can prevent personnel who have entered the underground working area from replacing or removing the positioning card without authorization.

[0040] When there are many people waiting in the waiting area, the signal receiving module broadcasts and notifies the positioning card that is more than 3 meters away from the first receiver A1 or the second receiver A2 to enter the slow-sending state; when the waiting person is equal to or less than 3 meters away from the first receiver A1 or the second receiver A2, the positioning card of the person is switched to the fast-sending state. That is, the identification preparation area and the detection area are both within 3 meters, and the waiting area is outside the 3-meter range. In order to control the coal mine from being overcrowded, there will be a large number of waiting personnel at the coal mine entrance during the shift change, and these people all carry positioning cards to prepare to enter the mine. At this time, the positioning card will continuously send positioning messages, resulting in air time slot collisions and data accumulation, affecting the speed and stability of the system. At this time, the positioning card in the waiting area is notified by the signal receiving module to enter the slow-sending state, which saves a lot of resources for the air channel, reduces invalid data, and improves the processing efficiency of the signal receiving module. When the personnel enter the identification preparation area, the positioning card switches to the fast-sending state, which reduces the delay and improves the reliability of the data.

[0041] like Figure 4 As shown, the present invention also provides a detection system for full-cycle positioning management of coal mine personnel working underground, and adopts a detection method for full-cycle positioning management of coal mine personnel working underground. The detection system includes: a biometric recognition module, which is installed in the detection area of ​​channel C and is used to perform biometric recognition of personnel entering / exiting the well; a signal receiving module, which is installed in the detection area of ​​channel C and is used to detect and verify the positioning cards of personnel entering / exiting the well.

[0042] The present invention mainly improves the following problems through improvement:

[0043] (1) Problems of cheating in the use of positioning cards: problems with replacing positioning cards underground, and problems with leaving positioning cards outside the working face area to avoid overload statistics. When the positioning card enters the well for inspection, it obtains a legal SN code, which is unique and automatically reset to the initial SN code when it is tripped. At this time, the system will automatically alarm. When the person leaves the well without legal SN code authorization, he cannot pass through the gate and can only be released after the penalty registration.

[0044] (2) Positioning card counterfeiting problem: Currently, positioning cards generally use fixed positioning card numbers. Once the air protocol is cracked or leaked, counterfeit cards will appear. The counterfeit card can still be used in the original system and cannot be detected. The newly designed SN code verification mechanism generates a random SN verification code each time it enters the well, and the system directly alarms for illegal SN codes. Those who fail to pass the SN code verification will not be allowed to go down the well. In addition, if the current personnel positioning system wants to eliminate counterfeit positioning cards, the signal receiving module, positioning card, substation, etc. must be upgraded and updated one by one, which is very difficult. With the SN code verification method, the upper computer only needs to change the encryption method of the SN verification code and then resend it to the signal receiving module to complete the replacement of the SN verification code, which can achieve a senseless upgrade.

[0045] (3) Time slot conflict problem of multiple positioning cards: By setting the positioning card in the wellhead waiting area to a slow-sending state, the time slot conflict problem of the positioning card waiting at the wellhead is improved. At the same time, the positioning card is switched to a fast-sending state in the identification preparation area to ensure the high timeliness of the data between the positioning card and the signal receiving module.

[0046] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
