Description

Technical Field

[0001] The present invention relates to the technical field of inspection of coal mine safety monitoring systems, and in particular to a maximum inspection cycle inspection system for coal mine safety monitoring. Background Art

[0002] The maximum inspection cycle of a coal mine safety monitoring system should not be greater than 20 seconds, and the maximum inspection cycle requirement is to be inspected under the condition of full system capacity. At present, the typical full-capacity configuration of an in-use coal mine safety monitoring system is 256 sub-stations, with 32 sensors connected to each sub-station; during the process of submitting the system for safety standard review, the maximum inspection cycle is a mandatory test item, and the full system capacity involves 256 sub-stations and 8,192 sensors. The equipment quantity involved in the maximum inspection cycle test process is huge, requiring a large amount of capital investment and human input.

[0003] Currently, during the inspection process of the maximum inspection cycle of a coal mine safety monitoring system, usually only part of the equipment is set up for verification, or 256 sub-stations are set up, and then sensor data is generated through a simulation program on the sub-stations. This method not only requires huge capital and human input to simulate sensor data on the sub-stations for verification; since this method lacks the data communication link between the sub-stations and the sensors, it cannot truly and effectively verify the maximum inspection cycle of the system. Summary of the Invention

[0004] One of the problems existing in the background art that the present invention aims to solve.

[0005] To this end, the present invention provides a maximum inspection cycle inspection system for coal mine safety monitoring.

[0006] The technical solution adopted by the present invention to solve its technical problems is:

[0007] A maximum inspection cycle inspection system for coal mine safety monitoring, comprising,

[0008] A host computer, in which a maximum inspection cycle inspection data configuration software is set, used for simulating alarm data configuration information;

[0009] A sensor flexible simulation device, which can automatically generate alarm simulation data of 32 sensors according to the alarm data configuration information in the host computer;

[0010] An automatic inspection module, which calculates the maximum inspection cycle of the system by monitoring the alarm process.

[0011] Further, the maximum inspection cycle test data configuration software includes an alarm data configuration module, a configuration information machine language conversion module, a configuration distribution module, and a distribution result verification module. The alarm data configuration module realizes the configuration and storage of the configuration information related to 32 sensors. The configuration information machine language conversion module converts the configuration information into 16 - bit machine code according to the communication protocol. The configuration distribution module distributes the converted machine code - formatted data configuration information to the sensor flexible simulation device through the network. The distribution result verification module is responsible for confirming and verifying whether the relevant configuration information has been successfully sent to the sensor flexible simulation device.

[0012] Further, in the alarm data configuration module, the configuration information related to 32 sensors includes the sensor RS485 communication parameters, the sensor address, the analog alarm value, and the duration of the analog value.

[0013] Further, the sensor flexible simulation device includes a network interface and multiple RS485 interfaces. The network interface is used for data communication with the configuration distribution module.

[0014] Further, after receiving the analog alarm data configuration information, the sensor flexible simulation device sequentially simulates the data of 32 sensors according to the analog alarm value and the duration in the configuration information. After receiving the time - slot command of the sub - station, it sequentially sends the simulated data of 32 sensors to each sub - station through the corresponding RS485 interface until the duration ends.

[0015] Further, it also includes an automatic screenshot module and an image analysis module. The automatic screenshot module is connected to the image analysis module, and the image analysis module is connected to the automatic inspection module. The automatic screenshot module real - time captures the operation interface of the upper computer display screen and sends the screenshot image to the image analysis module. The image analysis module extracts the graphic information at a specific position of the screenshot to identify the current number of sensor alarms and sends it to the automatic inspection module.

[0016] Further, after the number of recorded alarms in the automatic inspection module reaches 8192, which is the number of sensors with the full system capacity, the maximum inspection cycle is calculated based on the start time of the automatic timing.

[0017] The beneficial effects of the present invention are as follows. The maximum inspection cycle test data configuration software can configure the triggering conditions such as 32 sensor addresses, analog alarm data, and analog duration, and provide one-key automatic distribution of serialized analog conditions to the sensor flexible simulation device. After the sensor flexible simulation device returns a signal indicating successful reception, the maximum inspection cycle automatic test software starts automatic timing. After the sensor flexible simulation device analyzes the received data content, it simulates the 485 output signal to the substation in real time, and the substation transmits the execution result to the ground central station software of the coal mine safety monitoring system. After the ground central station software of the coal mine safety monitoring system analyzes and processes the uploaded result of the substation, it displays the alarm records and the number of alarm records in real time. The maximum inspection cycle automatic test software automatically takes screenshots of the alarm data page displayed by the ground central station software (taking a screenshot every 100 milliseconds) Figure 1 times), and uses image recognition and analysis technology to automatically extract the current number of alarm records. When the number of alarm records reaches 8192, the timing stops, and the maximum inspection cycle test result is automatically generated.

[0018] Therefore, the present invention realizes the simple, flexible, and fast configuration of system full-capacity test data. The analog alarm data of 8192 sensors only needs to be configured once, and at the same time, the one-key automatic distribution of the analog alarm data of 8192 sensors is realized. Without providing any sensor devices, it fully meets the requirements of system full-capacity inspection, greatly saving the equipment investment cost in the inspection process. It avoids the cumbersome and error-prone manual setting of sensor data in the existing inspection mode, improves the accuracy of the inspection process, and saves the time of manual participation.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] A maximum inspection cycle inspection system for coal mine safety monitoring includes a host computer, an automatic screenshot module, an image analysis module, an automatic inspection module, and a sensor flexible simulation device. Among them, the host computer is configured with maximum inspection cycle inspection data configuration software, and the automatic screenshot module, the image analysis module, and the automatic inspection module constitute the maximum inspection cycle automatic inspection software.

[0028] The maximum inspection cycle inspection data configuration software realizes the configuration of trigger conditions such as 32 sensor addresses, analog alarm data, and analog duration, and provides a one-key automatic transmission of serialized analog conditions to the sensor flexible simulation device. After the sensor flexible simulation device returns a reception success signal, the maximum inspection cycle automatic inspection software starts automatic timing; after the sensor flexible simulation device analyzes the received data content, it simulates the 485 output signal to the substation in real time, and the substation transmits the execution result to the coal mine safety monitoring system ground central station software. After the coal mine safety monitoring system ground central station software analyzes and processes the uploaded result of the substation, it displays the alarm record and the number of alarms in real time; the maximum inspection cycle automatic inspection software automatically captures the alarm data page displayed by the ground central station software (capturing once every 100 milliseconds) Figure 1times), and uses image recognition and analysis technology to automatically extract the current number of alarm messages. When the number of alarm messages reaches 8192, the timing stops, and the maximum inspection cycle test result is automatically generated.

[0029] Specifically, the maximum inspection cycle test data configuration software includes an alarm data configuration module, a configuration information machine language conversion module, a configuration distribution module, and a distribution result verification module. The alarm data configuration module realizes the configuration and storage of the configuration information related to 32 sensors. The configuration information machine language conversion module converts the configuration information into hexadecimal machine code according to the communication protocol. The configuration distribution module distributes the converted machine code format data configuration information to the sensor flexible simulation device through the network. The distribution result verification module is responsible for confirming and verifying whether the relevant configuration information is successfully sent to the sensor flexible simulation device. After successful sending, the automatic timing starts.

[0030] The sensor flexible simulation device is connected to the upper computer. The upper computer sends simulated alarm data configuration information to the sensor flexible simulation device. After receiving the simulated alarm data configuration information sent by the maximum inspection cycle test data configuration software, the sensor flexible simulation device automatically generates alarm simulation data for 32 sensors. Specifically, the sensor flexible simulation device includes a network interface and multiple RS485 interfaces. The network interface is used for data communication between the device and the maximum inspection cycle test data configuration software. In this embodiment, there are 16 RS485 interfaces, and the 16 RS485 interfaces are used for data communication between the device and the sub-stations.

[0031] Each RS485 interface of the sensor flexible simulation device is connected in series with a group of sub-stations (a group of sub-stations includes 16 sub-stations, and there is a main sub-station in each group of sub-stations. The main sub-station is responsible for periodically sending time slot commands to the simulation device, and other sub-stations only receive data on the RS485 line). After the device simulates the alarm data of 32 sensors, after receiving the time slot command sent by the main sub-station of any group of sub-stations, the device sends the simulated alarm data of 32 sensors through the corresponding RS485 interface; thus, a total of 8192 real-time alarm data of sensors are sent to 256 sub-stations in real time through a sensor flexible simulation device [32 (the device simulates 32 sensors) * 16 (16 RS485 channels) * 16 (1 group of sub-stations includes 16 sub-stations) = 8192].

[0032] It should be noted that the working processes of the large inspection cycle test data configuration software and the sensor flexible simulation device can be displayed on the display screen of the upper computer.

[0033] The automatic screenshot module captures the running interface of the upper computer's display screen in real time and sends the screenshot image to the image analysis module; the image analysis module extracts the graphic information at specific positions of the screenshot (this image area shows the current number of sensor alarms), automatically identifies the current number of sensor alarms, and sends the number of alarms to the automatic inspection module; the automatic inspection module automatically compares the number of alarms. When the number of alarms reaches 8192, the maximum number of sensors in the system's full capacity, the maximum inspection cycle is calculated based on the start time of the automatic timing; finally, combined with the requirement in the "General Technical Requirements for Coal Mine Safety Monitoring Systems" (AQ6201-2019) that the maximum inspection cycle should not be greater than 20 seconds, the inspection result of the maximum inspection cycle and the inspection detail data report are given. Ultimately, the unmanned automatic determination of the maximum inspection cycle is realized, avoiding the influence of uncertain factors in manual determination and improving the reliability of the entire inspection process.

[0034] A method for inspecting the maximum inspection cycle includes the following steps:

[0035] Step 1, configure data in the alarm data configuration module.

[0036] There are usually several sub-stations in the mine, and each sub-station is connected with 32 sensors. That is, the full-capacity sensor configuration of a single sub-station is 32. Therefore, it is necessary to configure the relevant analog alarm data configuration information of 32 sensors. The configuration information is specifically: the RS485 communication parameters of the sensor, the sensor address, the analog alarm value, and the duration of the analog value.

[0037] Step 2, data forwarding. The configuration information machine language conversion module converts the configuration information into hexadecimal machine code according to the communication protocol, and the configuration distribution module distributes the converted machine code format data configuration information to the sensor flexible simulation device through the network.

[0038] Step 3, data simulation

[0039] After the sensor flexible simulation device receives the analog alarm data configuration information sent by the maximum inspection cycle inspection data configuration software, it automatically generates the alarm simulation data of 32 sensors.

[0040] After receiving the analog alarm data configuration information, according to the analog alarm value and duration in the configuration information, it sequentially simulates the data of 32 sensors. After receiving the time slot command of the sub-station, it sequentially sends the analog data of 32 sensors to each sub-station through the corresponding RS485 interface until the duration ends.

[0041] In this embodiment, 16 RS485 interfaces are used for data communication between the device and the sub-stations. Each RS485 interface of the device is connected in series with a group of sub-stations (a group of sub-stations includes 16 sub-stations, and there is a master sub-station in each group of sub-stations. The master sub-station is responsible for sending time slot commands to the simulation device at regular intervals, and the other sub-stations only receive data on the RS485 line). After the device simulates 32 sensor alarm data, after receiving the time slot command sent by the master sub-station of any group of sub-stations, the device sends the simulated alarm data of 32 sensors through the corresponding RS485 interface, so as to send the real-time alarm data of a total of 8192 sensors to 256 sub-stations in real time through a sensor flexible simulation device.

[0042] Step 4: Result verification. The issued result verification module is responsible for confirming and verifying whether the relevant configuration information has been successfully sent to the sensor flexible simulation device. After successful sending, the automatic timing starts.

[0043] Repeat steps 1 to 4 until the number of alarms reaches the number of sensors with the full capacity of the system, which is 8192. Then, calculate and generate the maximum inspection cycle based on the start time of the automatic timing.

[0044] It should be noted that during the operation of the maximum inspection cycle automatic inspection software, the automatic screenshot module captures the operation interface of the ground central station system software in real time and sends the screenshot image to the image analysis module; the image analysis module extracts the graphic information at specific positions of the screenshot, automatically calculates the current number of sensor alarms, and sends the number of alarms to the automatic inspection module; the automatic inspection module automatically compares the number of alarms. When the number of alarms reaches the number of sensors with the full capacity of the system, which is 8192, the maximum inspection cycle is calculated and generated based on the start time of the automatic timing.

[0045] In summary, first, the maximum inspection cycle test data configuration software configured in the upper computer can realize the configuration of trigger conditions such as the RS485 communication parameters, sensor addresses, simulated alarm data, and simulated duration of 32 sensors. The user only needs to complete the configuration of one sensor, and the configuration of the remaining sensors is automatically generated with one key; after the sensor configuration is completed, the relevant configuration information can be automatically sent to the sensor flexible simulation device. The sending process automatically interacts and verifies with the device, and automatically prompts the sending result; while ensuring the accuracy of the data in the whole inspection process, it greatly saves the manual participation time.

[0046] Secondly, the sensor flexible simulation device can simulate RS485 communication data in real time according to the communication protocol between the sensor and the sub-station; and continuously send the corresponding communication data to the sub-station according to the set simulation duration. After receiving the sensing data, the sub-station transmits it to the ground central station system software in real time through the network environment. The ground central station system software automatically generates sensor alarm record data to generate alarm records according to the system service requirements, and calculates the maximum inspection cycle of the system.

[0047] Finally, the maximum inspection cycle automatic inspection software can monitor the working processes of the maximum inspection cycle inspection data configuration software and the sensor flexible simulation device in real time, automatically generate alarm records based on the visual recognition algorithm, automatically calculate the maximum inspection cycle of the system, save manpower investment, avoid the uncertainty influence of human factors, and greatly improve the reliability and credibility of the inspection results.

[0048] Furthermore, the present invention realizes the simple, flexible and fast configuration of the system full-capacity test data. The simulated alarm data of 8,192 sensors only need to be configured once, and at the same time, the simulated alarm data of 8,192 sensors are automatically sent in one key; without providing any sensor equipment, it fully meets the system full-capacity inspection requirements, greatly saving the equipment investment cost in the inspection process. It avoids the cumbersome and error-prone manual setting of sensor data in the existing inspection mode, improves the accuracy of the inspection process, and saves the time of manual participation.

[0049] The inspection solution provided by the present invention takes less than 3 minutes for a single verification time, supports multiple fast inspections with different alarm conditions; and greatly saves the time required for the inspection process while avoiding the random errors that may occur in a single inspection.

[0050] Taking the ideal embodiments according to the present invention as an inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
