Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mining equipment, and concretely relates to the safety optimization design of blasting process. BACKGROUND

[0002] With the development of science and technology, wisdom mine based on modern coal mine intelligent concept is paid more and more attention. Wisdom mine deeply integrates internet of things, cloud computing, big data, artificial intelligence, automatic control, industrial internet, robotized equipment and modern mine development technology, forms a complete intelligent system of mine comprehensive perception, real-time interconnection, analysis and decision, autonomous learning, dynamic prediction and collaborative control, and can realize intelligent operation of mine development, mining, transportation, sorting, safety guarantee, ecological protection and production management.

[0003] Among them, the application of electronic detonator is the most important part of wisdom mine. Because electronic detonator itself has extremely high risk, so it needs strict safety supervision in the use link. It is more and more important to integrate the safety verification of electronic detonator with modern intelligent technology to realize the safety production task of wisdom mine.

[0004] In the prior art, the electronic detonator arranged needs to be controlled and detonated by the blasting operator through the handheld initiator, for example, the electronic detonator initiation system disclosed in the Chinese patent document with the announcement number CN211824101U uses the above technical means, and a plurality of electronic detonators in parallel are detonated by the electronic detonator initiator. Usually, the initiator stores the verification information required for detonating electronic detonators, such as address information and time information. Usually, before performing the work of detonating electronic detonators, the blasting operator needs to download the verification information to his own initiator on a management device, and in this process, because the existing management device lacks additional verification function, the verification information can be downloaded at will. If the criminal steals the initiator and successfully downloads the verification information, it can realize illegal detonation of electronic detonators at different places and different times by tampering with the verification information, which seriously deviates from the safety supervision of mining operation and has great safety hazard. UTILITY MODEL CONTENT

[0005] The utility model aims at providing a mine-used initiation safety verification device, which can replace the existing management device to issue verification information, and has multiple safety verification capabilities on this basis, so as to avoid the theft of verification information and ensure the safety of electronic detonator detonation.

[0006] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0007] The mining detonation safety verification device comprises an explosion-proof shell 1 and a power supply assembly 2 installed in the explosion-proof shell 1, characterized in that it further comprises a verification assembly 3 installed in the explosion-proof shell 1 and connected with the power supply assembly 2; the verification assembly 3 comprises a processing unit 31 for data processing, and a face recognition assembly 32 and a communication assembly 33 electrically connected with the processing unit 31; a displacement detection assembly 4 connected with the processing unit 31 is arranged on the explosion-proof shell 1, and the displacement detection assembly 4 is used for identifying the position change of the explosion-proof shell 1 and sending a clearing instruction to the processing unit 31.

[0008] The power supply assembly 2, the verification assembly 3 and the displacement detection assembly 4 are installed in the explosion-proof shell 1, the power supply assembly 2 is used for providing power support for the verification assembly 3 and the displacement detection assembly 4, the verification assembly 3 is used for completing the receiving and sending of verification information and safety verification identification, and the displacement detection assembly 4 is used for identifying the position change of the explosion-proof shell 1.

[0009] The explosion-proof shell 1 is made of a strong anti-breaking material, such as aluminum alloy integrated molding, alloy welding or high-strength engineering plastic, which can not only adapt to the harsh dust and stone environment of the mine and protect the hardware structure safety of the core verification assembly 3, but also avoid being broken by illegal persons and stealing or tampering data.

[0010] The verification assembly 3 comprises a processing unit 31 for data processing, and a face recognition assembly 32 and a communication assembly 33 electrically connected with the processing unit 31. The face recognition assembly 32 is electrically connected with the processing unit 31, can realize the collection of face images through devices such as stereo cameras, binocular cameras, structured light cameras and infrared cameras, and send data to the processing unit 31 for comparison processing and analysis; the processing unit 31 can be realized based on existing hardware technologies such as ARM or FPGA, such as an STM32 series single-chip microcomputer designed based on an ARM Cortex-M core; the communication assembly 33 can use WIFI, Bluetooth, relay wireless network and other means to realize the bidirectional receiving and sending of information data and command instructions in the processing unit 31, so that the mining detonation safety verification device provided by the utility model can not only communicate with the cloud to receive and send original verification information, detonation plans, schedules and other data, but also can communicate wirelessly with a detonator to issue verification information.

[0011] The displacement detection component 4 is arranged on the explosion-proof shell 1, and is used for identifying position change of the explosion-proof shell 1 and sending a clearing instruction to the processing unit 31. The displacement detection component 4 can be realized by various means, such as an acceleration sensor, an ultrasonic sensor, an elastic mechanical reset button and the like matched with a signal processing unit. The main purpose is to send the clearing instruction to the processing unit 31. Specifically, taking the ultrasonic sensor as an example, all the blasters need to hold the initiator to the near field communication range of a specified download position (such as a specific room or a mine roadway wall) of a mine site to download the verification information before performing the detonation task.

[0012] After the device is placed and started, the displacement detection component 4 is initialized, then the device downloads the original verification information from the cloud through the communication component 33 and saves the original verification information; then the blaster downloads the verification information from the device after confirming the identity through face recognition.

[0013] In the above process, if the initiator does not correspond to the face recognition information of the carrying person, the device will not start the verification information distribution program, which reflects the identity verification feature. If there is a thief who steals or robs the device, the displacement detection component 4 will immediately obtain the displacement information of the explosion-proof shell 1, and then automatically send a clearing instruction to the processing unit 31. The clearing instruction can be a high / low level digital signal in the prior art, which will clear the original verification information saved in the memory of the processing unit 31 after being transmitted to a specific pin of the processing unit 31. This makes the stolen or robbed device unable to continue to perform the verification information distribution work after the displacement action. The above technical means endows the device with displacement verification capability, so that the initiator can only download the verification information at the specified location.

[0014] As a preferred embodiment of the utility model, the displacement detection component 4 comprises an ultrasonic sensor and a hidden shell mounted outside the probe of the ultrasonic sensor, and the ultrasonic sensor is mounted at the bottom plate of the explosion-proof shell 1.

[0015] The ultrasonic sensor has the advantages of strong concealment and high sensitivity, and is mainly based on ultrasonic distance sensing, and when arranged on the bottom plate of the explosion-proof shell 1, the displacement of the safety verification device in the placed state can be detected. When the safety verification device is placed on a horizontal plane and started, the ultrasonic sensor can automatically obtain the distance between the bottom plate of the explosion-proof shell 1 and the placed horizontal plane, and take the distance as an initial reference. Once the explosion-proof shell 1 is stolen, for example, moved away from the initial placement position, the distance detected by the ultrasonic sensor changes and is different from the initial reference, and then a clear instruction is automatically sent to the processing unit 31, and the clear instruction is a preset high / low level digital signal. The ultrasonic sensor can be realized by using existing products. The ultrasonic sensor probe is externally provided with a concealed shell which does not interfere with the transmission of ultrasonic signals, but cooperates with the explosion-proof shell 1 to shield the color of the ultrasonic sensor probe, so that the ultrasonic sensor probe cannot be easily visually identified, and potential criminals can be confused, and the detection concealment is improved.

[0016] As a preferred embodiment of the present application, the displacement detection assembly 4 comprises a push switch and a spring connected to the push switch, and the push switch is installed on the back plate of the explosion-proof shell 1.

[0017] The push switch is a mechanical structure, and when installed on the back plate of the explosion-proof shell 1, the displacement of the safety verification device hung on the wall can be detected. When the safety verification device is hung on the wall and started, the push switch is affected by the component force of the gravity of the explosion-proof shell 1, and will be automatically pressed against the wall and in a continuously pressed state. If the explosion-proof shell 1 is stolen, for example, taken off the wall, the spring connected to the push switch will pop up the push switch, so that the push switch automatically pops up and resets. At this time, a digital electrical signal will be triggered and sent to the processing unit 31, i.e. the clear instruction. The push switch can be realized by using existing products.

[0018] As a preferred embodiment of the present application, the verification assembly 3 further comprises an encryption assembly 34 arranged between the processing unit 31 and the communication assembly 33, and the encryption assembly 34 is used for providing encryption protection for the transmission of verification information.

[0019] The encryption assembly 34 is mainly used for providing encryption protection for the transmission of verification information. Since the verification information is confidential information, the device needs to encrypt the verification information during the process of receiving and issuing, so as to prevent criminals from intercepting and deciphering the wireless signal. It can be realized by means of the existing AES-CCM encryption chip and the like. In addition, the existing encryption assembly 34 all has the function of reverse decryption, and can perform decryption work on the received data.

[0020] As the preferred of the present utility model, the verification assembly 3 still contains the network card assembly connected with the processing unit 31 and the communication assembly 33 respectively, the network card assembly is used to store the MAC address.

[0021] The network card assembly is used to store the MAC address, the MAC address is the unique identity information of the safety verification device, and the data length can be 96bit, which is used to verify the effective identity of the current safety verification device.

[0022] As the preferred of the present utility model, the communication assembly 33 contains the LOAR module for long-distance communication.

[0023] The LOAR module can use the prior art means such as Anxinke Ra-03SCH module (transmission distance 5.1km, standby current 0.6mA) to realize long-distance communication, and the safety verification device can communicate with the cloud based on the LOAR module.

[0024] As the preferred of the present utility model, the mine detonation safety verification device further comprises an alarm assembly 5 installed on the explosion-proof shell 1 and used for reporting device abnormal state, and the alarm assembly 5 is electrically connected with the processing unit 31 and the displacement detection assembly 4.

[0025] The alarm assembly 5 is electrically connected with the processing unit 31 and the displacement detection assembly 4, when the displacement detection assembly 4 detects the displacement signal, the high / low level signal is sent to the alarm assembly 5 in parallel, the alarm assembly 5 is triggered and starts to alarm, and the processing unit 31 can control the alarm assembly 5 to close the alarm assembly 5 to prevent the continuous alarm behavior from adversely affecting the working environment. The alarm assembly 5 can sound and light alarm based on the buzzer or LED indicator in the prior art.

[0026] As the preferred of the present utility model, the mine detonation safety verification device further comprises a display assembly 6 installed on the explosion-proof shell 1, and the display assembly 6 is connected with the processing unit 31 and used for providing visual support for device state and verification information transmission process.

[0027] The display assembly 6 is connected with the processing unit 31 and used for providing visual support for device state and verification information transmission process. Specifically, the display assembly 6 can display the face image collected when the face recognition assembly 32 works, display the personal information of the blaster, display the verification information download process, and display the arrangement state of the safety verification device, etc. It can improve the use convenience and intuitiveness of the safety verification device.

[0028] As the preferred of the utility model, the mine detonation safety verification device further comprises a reset circuit connected with the processing unit 31 and used for restarting recovery.

[0029] The reset circuit is connected with the processing unit 31 and is used for restarting recovery. When the safety verification device is in an abnormal state due to false touch or failure, the reset circuit can reset the processing unit 31, so that the verification assembly 3 recovers to the initial state. Since the verification assembly 3 recovering to the initial state also eliminates the original verification information, the reset circuit does not affect the data security of the safety verification device.

[0030] As the preferred of the utility model, the mine detonation safety verification device further comprises a power supply detection circuit arranged between the power supply assembly 2 and the processing unit 31, and the power supply detection circuit is used for detecting and reporting power supply failure.

[0031] The power supply detection circuit can detect the power supply state of the power supply assembly 2 and realize functions such as voltage stabilization and filtering. If it detects power supply abnormality, it can also send failure information to the processing unit 31 and report to the cloud through the processing unit 31, so as to protect and monitor the state of the device.

[0032] In summary, the mine detonation safety verification device has the following advantages:

[0033] 1. By arranging the face recognition assembly 32 connected with the processing unit 31, identity security verification is realized, which makes only the blasting operator himself who passes the verification can download the verification information to his detonator, so as to realize the binding of the person and the detonator. Even if the detonator for specific electronic detonator detonation is stolen by illegal persons, it is also impossible to successfully download the verification information, which greatly improves the detonation safety of the electronic detonator.

[0034] 2. By arranging the displacement detection assembly 4 which can detect the position change of the explosion-proof shell 1 and send a clear instruction to the processing unit 31, displacement safety verification is realized, which makes the blasting operator himself can only successfully download the verification information at the initial placement position of the device. Specifically, even if the device is stolen by illegal persons, since the original verification information has been cleared by the clear instruction, illegal persons cannot obtain the verification information again, which also greatly improves the detonation safety of the electronic detonator.

[0038] The technical solutions of the embodiments of the utility model will be explained and described below in combination with the drawings of the embodiments of the utility model. However, the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0039] As shown in Figure 1 and Figure 2 , the explosion-proof housing 1 is installed with the power supply assembly 2, the verification assembly 3, the displacement detection assembly 4, the alarm assembly 5 and the display assembly 6. Among them, the power supply assembly 2 is used to provide power support for the verification assembly 3, the displacement detection assembly 4, the alarm assembly 5 and the display assembly 6; the verification assembly 3 is used to complete the transceiving and security verification identification of the verification information, the displacement detection assembly 4 is used to identify the position change of the explosion-proof housing 1, the alarm assembly 5 is used to accept the displacement signal of the displacement detection assembly 4 and alarm, and the display assembly 6 is used to provide visual support for the device state and verification information transmission process.

[0040] Among them, the verification assembly 3 contains the processing unit 31 for data processing, and the face recognition assembly 32 and the communication assembly 33 electrically connected with the processing unit 31. The verification assembly 3 is integrated on the mainboard, which can be an Android mainboard. The face recognition assembly 32 can realize the collection of face images through devices such as stereo camera / binocular camera, structured light camera, infrared camera, and send data to the processing unit 31 for comparison processing and analysis; the processing unit 31 can be realized based on the hardware technology such as ARM or FPGA in the prior art, such as STM32 series single-chip microcomputer based on ARM Cortex-M core design; the communication assembly 33 can use WIFI, Bluetooth, relay wireless network and other means to realize the bidirectional receiving and sending of information data and command instructions in the processing unit 31, so that the mine initiation safety verification device provided by the utility model can not only communicate with the cloud to transceive raw verification information, initiation plan, schedule and other data, but also can communicate wirelessly with the initiator to issue verification information. The encryption assembly 34 is mainly used for encryption protection for the transmission of verification information. Since the verification information is confidential information, the device needs to encrypt the verification information during the receiving and issuing process to prevent illegal persons from intercepting and deciphering the wireless signal. It can be realized based on the means such as AES-CCM encryption chip in the prior art. In addition, the existing encryption assembly 34 all has the function of reverse decryption, which can perform decryption work on the received data.

[0041] After the device is placed and powered on, the displacement detection component 4 is initialized, and then the device downloads the original verification information from the cloud through the communication component 33 and saves it; then the bomber confirms the identity through face recognition, and downloads the verification information from the device with the detonator in hand.

[0042] In addition, the processing unit 31 is connected with the displacement detection component 4, which can have multiple implementation ways.

[0043] In this embodiment, the displacement detection component 4 includes an ultrasonic sensor and a hidden shell installed outside the ultrasonic sensor probe, and the ultrasonic sensor is installed at the bottom plate of the explosion-proof shell 1.

[0044] The ultrasonic sensor has the advantages of strong concealment and high sensitivity, and is mainly based on ultrasonic distance sensing. When it is set at the bottom plate of the explosion-proof shell 1, it can detect the displacement of the safety verification device in the placed state. When the safety verification device is placed on a horizontal surface and started, the ultrasonic sensor can automatically obtain the distance between the bottom plate of the explosion-proof shell 1 and the placement horizontal surface, and take this distance as the initial reference. Once the explosion-proof shell 1 is stolen, for example, moved away from the initial placement position, the distance detected by the ultrasonic sensor changes and is different from the initial reference, then the ultrasonic sensor automatically sends a clear instruction to the processing unit 31, and the clear instruction is a pre-set high / low level digital signal. The ultrasonic sensor can be realized by using existing products. A hidden shell is provided outside the ultrasonic sensor probe. The hidden shell does not interfere with the transmission of ultrasonic signals, but cooperates with the explosion-proof shell 1 to color shield the ultrasonic sensor probe, so that the ultrasonic sensor probe cannot be easily visually identified, which can confuse potential criminals and improve the detection concealment.

[0045] Unlike the above embodiment, the displacement detection component 4 includes a push switch and a spring connected with the push switch, and the push switch is installed at the back plate of the explosion-proof shell 1.

[0046] The push switch is a mechanical structure, which is installed at the back plate of the explosion-proof shell 1 and can detect the displacement of the safety verification device hung on the wall. When the safety verification device is hung on the wall and started, the push switch is affected by the component force of the gravity of the explosion-proof shell 1, and will be automatically pressed against the wall in a continuous pressed state. If the explosion-proof shell 1 is stolen, for example, taken off the wall, the spring connected with the push switch will pop up the push switch, so that the push switch automatically pops up and resets. At this time, a digital electrical signal will be triggered and sent to the processing unit 31, that is, the clear instruction. The push switch can be realized by using existing products.

[0047] In another possible implementation, the verification component 3 further comprises an encryption component 34 disposed between the processing unit 31 and the communication component 33, and the encryption component 34 is configured to provide encryption protection for the transmission of the verification information. The encryption component 34 can be implemented based on the AES-CCM encryption chip in the prior art and the like. In addition, the existing encryption component 34 is provided with the function of reverse decryption, and can perform decryption work on the received data.

[0048] In another possible implementation, the verification component 3 further comprises a network card component connected with the processing unit 31 and the communication component 33 respectively, and the network card component is configured to store a MAC address, which is the unique identification information of the safety verification device, and the data length of the MAC address can be 96 bits, and the MAC address is used to verify the valid identity of the current safety verification device.

[0049] In another possible implementation, the communication component 33 comprises a LOAR module for long-distance communication. The LOAR module can be implemented based on the existing technical means such as the Anxinke Ra-03SCH module (transmission distance 5.1 km, standby current 0.6 mA), and is used for long-distance communication. The safety verification device can communicate with the cloud based on the LOAR module.

[0050] In another possible implementation, the alarm component 5 is based on the buzzer in the prior art, and when the buzzer receives the displacement signal from the displacement detection component 4, the buzzer is automatically turned on and emits a continuous and sharp buzzing sound to report the abnormal state of the device to the relevant supervisor.

[0051] In another possible implementation, the alarm component 5 is based on the LED indicator light in the prior art, and when the LED indicator light receives the displacement signal from the displacement detection component 4, the LED indicator light is automatically turned on and emits a specific color of light to report the abnormal state of the device to the relevant supervisor. In particular, the LED indicator light and the buzzer can be used in cooperation to provide multi-dimensional alarm reminders.

[0052] In another possible implementation, the mine detonation safety verification device further comprises a display component 6 installed on the explosion-proof shell 1, and the display component 6 is connected with the processing unit 31 and is configured to provide visual support for the device state and the transmission process of the verification information. Specifically, the display component 6 can display the face image collected by the face recognition component 32 when the face recognition component 32 works, display the personal information of the blaster, display the verification information download process, and display the arrangement state of the safety verification device, and the like. The display component 6 can improve the use convenience and intuitiveness of the safety verification device.

[0053] In another possible implementation, the mine-used detonation safety verification device further comprises a reset circuit connected with the processing unit 31 and used for restarting recovery. When the safety verification device is in an abnormal state due to false touch or failure, the reset circuit can reset the processing unit 31, so that the verification assembly 3 returns to the initial state. Moreover, since the verification assembly 3 returning to the initial state also eliminates the original verification information, the reset circuit does not affect the data security of the safety verification device.

[0054] In another possible implementation, the mine-used detonation safety verification device further comprises a power supply detection circuit arranged between the power supply assembly 2 and the processing unit 31. The power supply detection circuit can detect the power supply state of the power supply assembly 2 and realize the functions of voltage stabilization and filtering. If it detects an abnormal power supply, it can also send failure information to the processing unit 31 and report to the cloud via the processing unit 31, so as to realize the protection and state monitoring of the device.
