Description

Technical Field

[0001] The invention belongs to the technical field of underground positioning, and relates to a single card detection system and method for portable mining equipment. Background Art

[0002] In the coal mining industry, safety has always been one of the core concerns. With the advancement of technology, the underground personnel positioning system in coal mines has become a key means to improve the level of mine safety management. The underground environment of coal mines is complex and changeable, and the accuracy of the personnel positioning system is directly related to whether the people in distress can be quickly located and rescued in an emergency. Therefore, the standard emphasizes that the positioning card must not only have the real-time monitoring function of the working status, but also must ensure that each person going down the mine carries and only carries one exclusive positioning card to achieve the uniqueness of identity confirmation. This requires that portable positioning equipment for mines, including positioning cards, must be designed with highly reliable unique identification technology, such as through unique card number encoding to ensure that the identification information of each card and its corresponding passive card, motherboard, shell and other components is strictly consistent to prevent confusion, thereby ensuring the accuracy of positioning data.

[0003] The underground space of coal mines is small and the structure is complex, which places extremely high demands on the accuracy of the positioning system. The static positioning error is less than 0.3 meters, which means that the positioning system must have extremely high signal processing and anti-interference capabilities. This is directly related to the layout and optimization of the positioning antenna, requiring the antenna signal strength to not only meet basic communication needs, but also maintain stable signal transmission in complex environments to achieve positioning accuracy to meters, providing precise support for personnel safety management and accident emergency response.

[0004] In view of the particularity of the underground working environment of coal mines, the battery life of the positioning card has become a key factor affecting the overall performance of the system. Positioning cards with non-replaceable batteries must ensure a service life of at least 2 years, while positioning cards with replaceable batteries must maintain a service life of at least 6 months. This places strict requirements on battery selection, power management strategies, and battery status testing before leaving the factory. Ensuring that each positioning card reaches the standard battery voltage before being put into use is the basis for ensuring the long-term stable operation of the system.

[0005] Currently, production departments face many challenges in the production process of portable positioning equipment for mining. Identification and labeling, classification, precise assembly and individual testing in manual operation mode are not only time-consuming and labor-intensive, but also prone to errors due to human factors, affecting production efficiency and product quality. In particular, traditional card inspection systems lack effective shielding mechanisms, making it difficult to achieve precise operation, and often require additional manual intervention to isolate non-target devices, further reducing efficiency. At the same time, antenna strength and battery voltage detection usually need to be performed on different systems, increasing the complexity and cost of the detection process. Summary of the invention

[0006] In view of this, the object of the present invention is to provide a single card detection system and method for a portable mining device, which can realize comprehensive, efficient and accurate detection of a portable mining positioning device through an integrated and automated detection process.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] In one aspect, the present invention provides a single card detection system for a portable mining device, comprising:

[0009] The infrared module is used to detect whether a device to be detected enters the detection area and report to the MCU module;

[0022] Furthermore, the camera module is also used to identify the state of the detection area and feed it back to the server; the identification of the state of the detection area includes:

[0023] Observe whether there are any devices to be tested in the testing area;

[0024] Observe whether there is any problem in the process of removing abnormal devices from the normal queue;

[0025] Observe whether there is any problem in the process of rewriting the information of the device to be tested;

[0026] Check whether the indicator light on the device to be tested is normal.

[0027] Furthermore, the abnormal conditions include: the passive read-write module cannot read the passive card number; the camera module cannot recognize the shell card number; the UWB module cannot read the mainboard card number; the passive card number is inconsistent with the shell card number; the mainboard card number is inconsistent with the shell card number; the passive card number is inconsistent with the mainboard card number; the antenna RSSI signal strength read by the UWB module does not match the set range; the battery voltage read by the UWB module does not match the set range; the chip MAC address read by the UWB module is not unique; when an abnormal situation occurs, the MCU module starts the alarm module to alarm, the display module displays an alarm prompt, and starts the mechanical removal module to remove the abnormal device from the normal device queue.

[0028] Furthermore, the setting range of the RSSI signal strength is RSSI value ≥ 800; the setting range of the battery voltage is battery voltage ≥ 3.6v; the chip MAC address is not repeated with the previously detected chip MAC address and is unique.

[0029] On the other hand, the present invention provides a single card detection method for a portable mining device. Based on the single card detection system, the method comprises the following steps:

The MCU module compares the detection results. When all the results are consistent and unique, and the device antenna RSSI signal strength, device battery voltage, and chip MAC address read by UWB meet the set conditions, the device is considered normal, and the device is transmitted out of the detection area through the mechanical transmission module and returned to the normal queue; otherwise, the device is considered abnormal, and the device is removed from the normal queue through the mechanical removal module, and an alarm is sounded through the alarm module.

[0040] like Figure 1 As shown, the present invention provides a single card detection system for a portable mining device, comprising:

[0041] The infrared module is used to detect whether a device to be detected enters the detection area and report to the MCU module;

[0042] Shielding module: used to shield wireless signals;

[0043] The card inspection module is used to select one or more inspection items according to the server instruction, and the inspection items include passive reading and writing, video recording and UWB signal reading and writing;

[0044] Passive read / write module, used to read and write the passive card of the device;

[0045] The camera module is used to identify the unique identification on the device housing; it is also used to identify the status of the detection work area and feed it back to the server;

[0046] UWB module, used to read and write the unique identification of the device's circuit board, read the device's antenna RSSI signal strength, read the device's battery voltage, and read the chip's MAC address;

[0047] The MCU module is used to control the operation of each module and determine abnormal conditions during the detection process. The MCU module is also used to send an interrupt instruction to the mechanical transmission module and the mechanical removal module, and send an alarm prompt to the display module and the alarm module when receiving information sent by the infrared module when it recognizes that part of a person's body has entered the detection area.

[0048] A mechanical transport module for transferring equipment into or out of the inspection area;

[0049] Mechanical removal module, used to remove abnormal equipment from the normal queue;

[0050] An alarm module is used to alarm when an abnormal situation occurs during the detection process;

[0051] Display module, used to display data, alarm prompts, and processing methods during the detection process;

[0052] The server is connected to the MCU module through the RJ45 module and is used to manage and command each module.

[0053] like Figure 2 As shown, based on the above detection system, the present invention proposes a single card detection method for a portable mining device, comprising the following steps:

[0054] The device to be inspected is placed in the mechanical transmission module for transmission; when the infrared module in the detection area recognizes that the device to be inspected has entered the detection area, the shielding module is started to shield the wireless signal; the card inspection module selects one or more of the three tasks of passive reading and writing, video recording, and UWB signal reading and writing for detection, and sends the detection results to the MCU module. The MCU module compares the detection results. When all the results are consistent and unique, and the device antenna RSSI signal strength, device battery voltage, and chip MAC address read by UWB meet the set conditions, the device is considered normal, and the device is transmitted out of the detection area through the mechanical transmission module and returned to the normal queue; otherwise, the device is considered abnormal, and the device is removed from the normal queue through the mechanical removal module, and an alarm is sounded through the alarm module.

[0055] like Figure 3 The specific execution process of the detection system shown is as follows: first, the infrared module is used to determine whether there is a product entering the detection work area. If not, the shielding layer and the card inspection module are on standby; if so, the shielding layer is opened and the card inspection module is started.

[0056] The card inspection module is wirelessly connected to the passive reading and writing module and the UWB module, and is wiredly connected to the camera module, and is used to select one, two or three of the passive reading and writing module, the camera module and the UWB module for card inspection.

[0057] When the passive read / write module is selected to check the card, the passive card of the device is read and written to determine whether the passive card number is read. If not, the alarm module is notified to alarm and upload to the server. If it is read, it is determined whether the passive card number needs to be changed to make the passive card number consistent with the unique identifier on the shell of the subsequent detection.

[0058] When the camera module is selected to check the card, the unique identifier on the device shell is identified. If it is not identified, the alarm module is notified to alarm and upload it to the server. If it is identified, it is determined whether the unique identifier on the shell is consistent with the passive card number read or modified by the passive read-write module. If they are inconsistent, the alarm module is notified to alarm and upload it to the server. If they are consistent, the detection passes.

[0059] When the UWB module is selected for card inspection, the unique identification of the circuit board of the device is read and written by the UWB module, the antenna RSSI signal strength of the device is read, the battery voltage of the device is read, and the MAC address of the chip is read. If any information is not read, the alarm module is notified to alarm and upload to the server; if the antenna RSSI signal strength does not reach the set range (RSSI value ≥ 800), or the battery voltage of the device does not reach the set range (battery voltage ≥ 3.6v), or the MAC address is not unique, the alarm module is also notified to alarm and upload to the server; in addition, if the UWB module does not read the unique identification of the circuit board of the device, or the unique identification of the circuit board of the device is inconsistent with the unique identification on the shell, or the passive card number read or modified by the passive read-write module is inconsistent, the alarm module is also notified to alarm and upload to the server; otherwise, the detection is passed. The UWB module can also make the unique identification of the circuit board consistent with the other two unique identifications by changing the motherboard card number.

[0060] The equipment that issues an abnormal alarm will be removed from the normal queue by the mechanical removal module and stored separately for subsequent processing.
