Description

Technical Field

[0001] This disclosure pertains to the field of anti-collision technology for mobile coke oven machinery, and in particular to an anti-collision system, method and apparatus, electronic device and computer-readable storage medium for mobile coke oven machinery. Background Technology

[0002] With the advancement of technology, intelligentization has become an essential feature and function of equipment. While intelligentization is the ultimate goal, safe operation of equipment is its fundamental guarantee. Especially for large-scale machinery with complex structures, intricate movements, and interconnected mechanical links, intelligentization is an inevitable trend, but safe production is of paramount importance. Given this working condition and in conjunction with existing projects, developing an anti-collision function is urgently needed.

[0003] Based on a large-scale coking project abroad, this disclosure explores the vertical thinking during the installation and commissioning process, opening up new ideas for future project design and execution. For example, an ongoing project includes three sets of coke pushers, three sets of coke catchers, three sets of coal packers, and three sets of locomotives, all of which are mobile devices running on the same fixed track. Therefore, if the equipment fails or the operators lack a sense of responsibility, there is a possibility of collisions between two or more pieces of equipment running at the same time, posing a significant safety hazard.

[0004] The information disclosed in this background section is intended only to enhance understanding of the overall background of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this disclosure is to address the potential for collisions and significant safety hazards posed by two or more mobile devices operating simultaneously on the same fixed track. This disclosure provides a collision prevention system, method, and apparatus for coke oven mobile machinery, electronic equipment, and a computer-readable storage medium.

[0006] The first aspect of this disclosure provides a collision avoidance system for a coke oven mobile machine. The system includes: a fixed track; the coke oven mobile machine, including: a machine body and rollers that cooperate with the fixed track, the rollers being able to move on the fixed track; an coded position recording device, including: an encoder mounted on the rollers, the encoder being used to record the movement position of the coke oven mobile machine; an infrared collision avoidance device, including: a reflector and an infrared transceiver mounted on the machine body, the infrared transceiver being used to emit infrared light to the reflector and receive the emitted signal from the reflector, and to send infrared transmission and reception information; a limit device, installed at a limit position of the coke oven mobile machine, used to record limit information when the coke oven mobile machine moves to the limit position; and a logic controller, connected to the coke oven mobile machine, the coded position recording device, the infrared collision avoidance device, and the limit device respectively, receiving in real time the movement position of the coded position recording device, the infrared transmission and reception information of the infrared collision avoidance device, and the limit information of the limit device, and controlling the coke oven mobile machine to decelerate or brake based on the movement position, the infrared transmission and reception information, and the limit information.

[0007] The second aspect of this disclosure provides a method for preventing collisions with a coke oven mobile machine. The method includes: receiving in real-time the movement position of an coded position recording device, infrared transceiver information from an infrared anti-collision device, and limit information from a limit device; the coded position recording device includes an encoder mounted on a roller of the coke oven mobile machine, the roller cooperating with a fixed track; the infrared anti-collision device includes a reflector and an infrared transceiver on the machine body of the coke oven mobile machine, the infrared transceiver emitting infrared light to the reflector and receiving the emitted signal from the reflector, and sending infrared transceiver information; the limit device is installed at a limit position on the coke oven mobile machine, used to record limit information when the coke oven mobile machine moves to the limit position; and controlling the coke oven mobile machine to decelerate or brake based on the movement position, infrared transceiver information, and limit information.

[0008] This disclosure provides a collision avoidance device for a coke oven mobile machine, comprising: a receiving unit configured to receive in real time the movement position of an coded position recording device, infrared transceiver information from an infrared collision avoidance device, and limit information from a limit device; the coded position recording device comprising: an encoder mounted on a roller of the coke oven mobile machine, the roller cooperating with a fixed track; the infrared collision avoidance device comprising: a reflector and an infrared transceiver on the mechanical body of the coke oven mobile machine, the infrared transceiver being used to emit infrared light to the reflector and receive the emitted signal from the reflector, and to send infrared transceiver information; a limit device installed at a limit position of the coke oven mobile machine, used to record limit information when the coke oven mobile machine moves to the limit position; and a control unit configured to control the deceleration or braking of the coke oven mobile machine based on the movement position, the infrared transceiver information, and the limit information.

[0009] A fourth aspect of this disclosure provides an electronic device comprising: at least one processor; and a memory communicatively connected to the at least one processor, wherein the memory stores instructions executable by the at least one processor to enable the at least one processor to perform a method as described in any implementation of the second aspect.

[0010] The fifth aspect of this disclosure provides a non-transitory computer-readable storage medium storing computer instructions for causing a computer to perform the method described in any implementation of the second aspect.

[0011] Compared with existing technologies, the technical effects achieved by this disclosure are as follows: By acquiring the position information of the coke oven's moving machinery through multiple methods such as coded position recording devices, infrared anti-collision devices, and limit devices, the probability of collision accidents can be greatly reduced compared to a single monitoring method, effectively protecting the safety of equipment and personnel. The limit devices function at specific limiting positions, further ensuring accurate braking control at critical locations and avoiding dangerous situations such as collisions caused by inaccurate position monitoring. The real-time braking control method, based on multiple information sources, is more reliable than some simple, non-real-time braking control methods. It can respond promptly to various situations, ensuring accurate braking when needed and avoiding accidents caused by untimely braking. Attached Figure Description

[0016] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0017] The technical solutions of this disclosure are illustrated below through specific embodiments. It should be understood that one or more steps mentioned in this disclosure do not preclude the existence of other methods and steps before or after the combined steps, or that other methods and steps may be inserted between these explicitly mentioned steps. It should also be understood that these examples are for illustrative purposes only and are not intended to limit the scope of this disclosure. Unless otherwise stated, the numbering of each method step is only for the purpose of identifying each method step, and not to limit the order of each method or to limit the scope of implementation of this disclosure. Changes or adjustments to their relative relationships, without substantial changes to the technical content, can also be considered as within the scope of implementation of this disclosure.

[0018] The raw materials and instruments used in the examples are not subject to any specific restrictions on their source; they can be purchased from the market or prepared according to conventional methods known to those skilled in the art.

[0019] Traditional methods for preventing collisions with moving machinery in coke ovens mainly employ the following approaches:

[0020] 1) Limit switch method: Limit switches are installed on the tracks or equipment of the coke oven moving machinery. When the machinery reaches the set limit position, the limit switch is triggered, thereby cutting off the power or sending a signal to stop the machinery and prevent collisions with other machinery or obstacles. The trigger position of the limit switch is relatively fixed, which makes it less adaptable to complex operating environments and dynamically changing collision risks, and it cannot provide early warning and handle some emergencies.

[0021] 2) Radar ranging method: This method utilizes the principle of radar emitting electromagnetic waves and receiving reflected waves to measure the distance between the moving machinery of the coke oven and obstacles in front. When the detected distance is less than a set safe distance, an alarm or automatic shutdown device is triggered. This method is relatively expensive, and radar signals may be interfered with by other electromagnetic devices, leading to decreased measurement accuracy or false alarms.

[0022] 3) Laser ranging method: This method determines the distance between the moving coke oven machinery and obstacles by emitting a laser beam and measuring its reflection time. When the distance is below a set threshold, corresponding anti-collision measures are taken. Laser ranging equipment has high environmental requirements; dust, smoke, etc., may affect the propagation and reflection of the laser, leading to increased measurement errors. Furthermore, the equipment and maintenance costs are relatively high.

[0023] 4) Wireless communication technology method: This method utilizes wireless communication technologies (such as Bluetooth) to transmit and share the operating status and location information of mobile machinery in the coke oven in real time. By analyzing this data, it can determine whether there is a risk of collision and issue timely warnings or control commands. A reliable wireless communication network is required to ensure the stability and real-time performance of data transmission. Furthermore, the installation and debugging of communication equipment are complex and costly.

[0024] 5) Speed ​​Limit and Restricted Area Setting Method: In the coke oven mobile machinery control and management system, restricted areas and speed limit areas are set for vehicles based on production needs and safety requirements. When machinery enters a restricted area or exceeds the speed limit, the system will issue a warning or take mandatory measures, such as automatic deceleration or stopping. This method is relatively passive and cannot effectively respond to some sudden collision risks outside the restricted area or speed limit range in a timely manner.

[0025] 6) Mechanical structure optimization method: This method optimizes the structure of the moving machinery of the coke oven, such as adding protective devices and adjusting the layout and size of the equipment, to reduce the possibility of collisions or reduce the damage caused by collisions. Optimization design needs to be carried out during the mechanical manufacturing stage. It is difficult to modify existing equipment and cannot fundamentally eliminate the risk of collisions; it can only play a certain auxiliary role.

[0026] The aforementioned anti-collision methods for various mobile coke oven machinery operate independently, each only offering protection in a specific aspect. They fail to integrate multiple control information sets to achieve comprehensive protection. Traditional designs sometimes focus solely on hardware, and others solely on software, both exhibiting inherent design flaws. Furthermore, cultural differences across countries and regions, varying operator skills and levels of responsibility, and the harsh conditions and inadequate equipment maintenance at coke plants all contribute to frequent equipment collisions.

[0027] To address the shortcomings of existing technologies, this disclosure provides a collision avoidance system for moving coke oven machinery. Figure 1A schematic diagram of an embodiment of a coke oven mobile machinery anti-collision system is shown. The system includes: a fixed track 1, a coke oven mobile machinery 2, an encoded position recording device 3, an infrared anti-collision device 4, a limit device 5, and a logic controller. The coke oven mobile machinery 2 includes: a machinery body 20 and rollers that cooperate with the fixed track 1, and the rollers can move on the fixed track 1. The encoded position recording device 3 includes: an encoder 31 mounted on the rollers, which records the movement position of the coke oven mobile machinery 2. The infrared anti-collision device 4 includes: a reflector 41 and an infrared transceiver mounted on the machinery body 20. The infrared transceiver 42 is used to emit infrared light to the reflector 41 and receive the emission signal from the reflector 42, and send infrared transmission and reception information. The limit device 5 is installed at the limit position of the coke oven moving machine 2, and is used to record the limit information when the coke oven moving machine 2 moves to the limit position. The logic controller is connected to the coke oven moving machine, the coded position recording device, the infrared anti-collision device and the limit device respectively, and receives the movement position of the coded position recording device, the infrared transmission and reception information of the infrared anti-collision device and the limit information of the limit device in real time. Based on the movement position, the infrared transmission and reception information and the limit information, the logic controller controls the coke oven moving machine 2 to decelerate or brake.

[0028] In this embodiment, the coke oven mobile machinery is a large-scale mechanical device that serves as a core supporting equipment in the coke oven production process. It may include: coal charging cars, coke pushing cars, coke quenching cars, coke quenching cars, electric locomotives, and flue gas guiding cars. One coke oven mobile machinery can operate on a fixed track, and multiple coke oven mobile machinery can also operate simultaneously on a fixed track.

[0029] In this embodiment, the roller includes a driving roller 21 and a driven roller 22. The encoder 31 is mounted on the driven roller 22 and encodes as the driven roller 22 moves.

[0030] In this embodiment, there can be multiple infrared transceivers 42 installed on the mechanical body 20. These multiple infrared transceivers 42 can receive infrared light emitted not only from the reflector 41 on the coke oven mobile machinery itself, but also from the emitters 41 on other mobile machinery, thereby effectively calculating the distance between the coke oven mobile machinery and other mobile machinery. It should be noted that the reflector 41 of the infrared anti-collision device 4 can be installed not only on the coke oven mobile machinery, but also on one side of the fixed track 1, which facilitates effective restriction of the movement position of the coke oven mobile machinery.

[0031] In this embodiment, the infrared transceiver information is information sent from one infrared anti-collision device to another. This infrared transceiver information includes the times when the infrared anti-collision device sends and receives infrared light, as well as parameters (such as the infrared light transmission speed) used to calculate the corresponding distance. It should be noted that the infrared light sent by the infrared anti-collision device on the same coke oven mobile machinery is received by a reflector mounted on it, and the propagation distance of the infrared light is a fixed value. The propagation distance of the infrared light between different coke oven mobile machinery will vary depending on the distance between them.

[0032] Infrared anti-collision device: Used for deceleration and stopping between two coke oven moving machines and between the coke oven moving machine and the ground end platform. This device can be set by parameters. When it reaches a certain range, it will send a passive switch signal to the logic controller to decelerate; when it reaches another range, it will send a passive switch signal to the logic controller to stop.

[0033] The encoder in the coding position recording device is installed on the driven wheel of the coke oven mobile machinery to reflect the walking position of the coke oven mobile machinery in real time. Specifically, the encoder can be an incremental encoder, and the distance calculated by the encoder is shown in Equation (1).

[0034]

[0035] In equation (1), S represents the travel distance, K represents the number of encoder revolutions, R is the radius of the driven wheel of the coke oven moving machinery, and N is the number of encoder pulses.

[0036] Optionally, to achieve unmanned and intelligent operation, the aforementioned anti-collision system for coke oven mobile machinery may also include: an automatic alignment system that allows the alignment accuracy of the coke oven mobile machinery to reach ±5mm. This system enables the coke oven mobile machinery to achieve soft anti-collision function, and can also use ground code disks and encoders in conjunction to achieve the functions of trolley deceleration and stopping.

[0037] Optionally, the above-mentioned anti-collision system for coke oven mobile machinery may also include: a mechanical limit switch. When the infrared anti-collision device fails, the automatic alignment system fails, or the encoder of the coded position recording device fails, the mechanical limit switch installed on the ground transmits the deceleration and stopping passive switch signals to the coke oven mobile machinery, thereby realizing the forced stop function of power failure of the control circuit of the coke oven mobile machinery.

[0038] In this embodiment, the movement distance of the coke oven mobile machinery can be determined by the movement position, the distance between the coke oven mobile machinery and other machinery can be determined by the infrared anti-collision device, and whether the coke oven mobile machinery exceeds its own trajectory can be determined by the limit information. The above-mentioned control of the coke oven mobile machinery to decelerate or brake based on the movement position, infrared transmission and reception information, and limit information includes: responding to the infrared transmission and reception information indicating no other coke oven mobile machinery and the limit information not indicating a limit target (the limit target is a position limit set for the coke oven mobile machinery, such as a limit target of 0), based on the movement position, detecting whether the distance between the coke oven mobile machinery and a preset target is less than a first preset distance or less than a second preset distance, wherein the second preset distance is less than the first preset distance; responding to the detection that the distance between the coke oven mobile machinery and the preset target is less than the first preset distance, controlling the coke oven mobile machinery to decelerate; responding to the detection that the distance between the coke oven mobile machinery and the preset target is less than the second preset distance, controlling the coke oven mobile machinery to brake; wherein, the preset target can be a travel target set for the coke oven mobile machinery, and the preset target can be a limit value set in hardware, such as a ground support. The preset target can also be a position value set by software for a specific location on a fixed track.

[0039] In this embodiment, the first set distance and the second set distance can be set based on development needs, such as the first set distance being 15m and the second set distance being 5m.

[0040] The aforementioned control of deceleration or braking of the coke oven mobile machinery based on movement position, infrared transceiver information, and limit information includes: in response to detecting that the limit information indicates that the limit target has not been reached and the movement position indicates that the distance between the coke oven mobile machinery and the preset target is greater than a first set distance, based on the infrared transceiver information, detecting whether the distance between any two of the at least two coke oven mobile machinery is less than the first set distance or less than a second set distance; in response to detecting that the distance between the two coke oven mobile machinery is less than the first set distance, controlling the two coke oven mobile machinery to decelerate; and in response to detecting that the distance between the two coke oven mobile machinery is less than the second set distance, controlling the two coke oven mobile machinery to brake.

[0041] Optionally, the above-mentioned control of the coke oven moving machinery to decelerate or brake based on the moving position, infrared transceiver information and limit information further includes: determining that the information representing deceleration or stopping is received for the first time among the moving position, infrared transceiver information and limit information, and controlling the coke oven moving machinery to decelerate or brake based on the information.

[0042] Optionally, the above-mentioned control of the coke oven mobile machinery to decelerate or brake based on the movement position, infrared transceiver information, and limit information further includes: responding to the limit information not reaching the limit target, determining the position of obstacles around the coke oven mobile machinery based on the infrared transceiver information; determining the current speed of the coke oven mobile machinery based on the movement position; determining the safe distance between the coke oven mobile machinery and the obstacles based on the obstacle position and the current speed; and controlling the coke oven mobile machinery to decelerate or brake based on the safe distance. The safe distance is not just a fixed value, but is related to the speed and acceleration of the machinery and the type of obstacle (if it can be distinguished). For example, the faster the speed, the larger the required safe distance. Specifically, the above-mentioned control of the coke oven mobile machinery to decelerate or brake based on the safe distance includes: determining distance parameters based on the safe distance, including: far distance, near distance, high speed, slow speed, etc. Using fuzzy control logic, the distance parameters are converted into a nonlinear output result of output deceleration force value or braking signal.

[0043] Optionally, the above-mentioned control of deceleration or braking of the coke oven mobile machinery based on movement position, infrared transceiver information, and limit information further includes: responding to the failure of the limit information to reach the limit target, predicting the movement trajectory of the coke oven mobile machinery based on the movement position and combined with machine learning algorithms or Kalman filtering; calculating the collision probability of dynamic obstacles detected by infrared rays based on infrared transceiver information and movement trajectory, and obtaining the collision probability calculation result. Based on the collision probability calculation result, a smooth deceleration curve is dynamically generated, rather than abrupt braking. For example, when the risk is low, the deceleration is gradual to conserve power and avoid unnecessary stops; when the risk is high, a faster deceleration is performed.

[0044] Optionally, the infrared transceiver information can also characterize the distance between the infrared transceiver 42 on the coke oven mobile machinery and the reflector 41 on the fixed track 1. The above-mentioned control of the coke oven mobile machinery to decelerate or brake based on the moving position, infrared transceiver information, and limit information also includes: in response to the limit information not reaching the limit target, determining a first distance between the coke oven mobile machinery and the reflector on the fixed track based on the infrared transceiver information; verifying whether the moving position is correct through the first distance; when the moving position is verified to be correct, constructing a digital twin model of the coke oven mobile machinery according to the moving position, simulating the operating state of the coke oven mobile machinery in real time, and preset a "safety boundary" in the virtual model. When the actual position approaches the boundary, the system triggers deceleration in advance (even if the infrared does not detect a physical obstacle); and controlling the coke oven mobile machinery to brake in response to the limit information reaching the limit target.

[0045] The anti-collision system for coke oven mobile machinery provided in this embodiment acquires the position information of the coke oven mobile machinery through multiple methods, including an coded position recording device, an infrared anti-collision device, and a limit device. Compared with a single monitoring method, this significantly reduces the probability of collision accidents and effectively protects the safety of equipment and personnel. The limit device functions at specific limiting positions, further ensuring accurate braking control at critical locations and avoiding dangerous situations such as collisions caused by inaccurate position monitoring. The real-time braking control method, based on multiple information sources, is more reliable than some simple, non-real-time braking control methods. It can respond promptly to various situations, ensuring accurate braking when needed and preventing accidents caused by untimely braking.

[0046] Among the alternative implementations disclosed herein, such as Figure 1 As shown, the coding position recording device also includes: a reading head 32, which is installed on the coke oven moving machine 2; multiple code disks 33, which are evenly fixed on one side of the fixed track 1 at a preset distance, and the reading head 32 moves to the area that cooperates with each code disk 33 to record the alignment position of the coke oven moving machine 2 in real time; and an alignment sub-device, which is used to correct the movement position according to the alignment position.

[0047] In this optional implementation, before the coke oven mobile machinery starts operating, the system controlling the reading head 32 and the code disk 33 is initialized to ensure that all equipment is working properly. When the coke oven mobile machinery 2 runs along the fixed track 1, the reading head 32 continuously scans the code disk 33 on one side of the track. Each time the reading head 32 passes a code disk 33, it reads the encoded information on the code disk 33 and transmits this information to the alignment sub-device. The alignment sub-device calculates the deviation between the actual position of the machinery and the preset alignment position based on the read encoded information. If a deviation exists, the alignment sub-device issues a command to adjust the position of the coke oven mobile machinery, returning it to the correct alignment position. Throughout the entire operation, the reading head 32 and the alignment sub-device work continuously, monitoring and correcting the position of the machinery in real time to ensure it is always in a precise alignment state. Through the cooperation of the reading head 32 and the code disk 33, high-precision position detection and alignment can be achieved, improving the operating accuracy of the coke oven mobile machinery. The coke oven mobile machinery anti-collision system can monitor the position of the machinery in real time, promptly detect and correct deviations, ensuring that the machinery is always in a safe and accurate operating state. The combination of encoders and read heads is a mature technology with high reliability and stability, suitable for complex industrial environments. The encoder and read head have a relatively simple structure, low maintenance costs, and are easy to install and debug.

[0048] In some embodiments of this disclosure, such as Figure 1As shown, the aforementioned limiting device 5 includes: a vehicle support 51, installed on the coke oven mobile machinery 2; and a ground support 52, installed at one or both ends of the fixed track 1, which cooperates with the vehicle support 51 to force the coke oven mobile machinery 2 to stop.

[0049] In this optional implementation, the vehicle-mounted support 51 is installed on the coke oven mobile machinery 2, located at the front end or both sides of the coke oven mobile machinery 2. The vehicle-mounted support 51 is made of high-strength material, possessing sufficient strength and stability to withstand significant impact forces in emergency situations. The shape and dimensions of the vehicle-mounted support 51 are designed to fit closely with the ground support 52, ensuring rapid and reliable contact with the ground support 52 and the generation of a braking effect in emergency situations.

[0050] In this optional implementation, the ground support 52 is installed at one or both ends of the fixed track 1, cooperating with the vehicle support 51. The ground support 52 is also made of high-strength material, and its shape and size are designed to fit tightly with the vehicle support 51, ensuring rapid and reliable contact and braking effect in emergency situations. The ground support 52 can be designed as fixed or adjustable, depending on actual needs.

[0051] The anti-collision system for mobile coke oven machinery provided in this embodiment, with the cooperation of the on-vehicle support 51 and the ground support 52, can quickly and reliably stop the machinery in an emergency, further improving the safety and reliability of the system.

[0052] In some optional implementations of this disclosure, there are at least two coke oven mobile machines; the logic controller determines the mechanical distance between any two coke oven mobile machines based on the infrared transceiver information, movement position and limit information of each coke oven mobile machine, determines the control signal of the two coke oven mobile machines based on the mechanical distance, and controls the braking of the two coke oven mobile machines through the control signal.

[0053] In this optional implementation, infrared anti-collision devices, coded position recording devices, and limit devices are installed on each corner of at least two coke oven mobile machines. The movement position of any two of the at least two coke oven mobile machines indicates that the distance between the mobile machine and its respective preset target is greater than a first preset distance. When the limit information of the two coke oven mobile machines indicates that the limit target has not been reached, based on the infrared transmission and reception information of the two coke oven mobile machines, it is detected whether the distance between the two coke oven mobile machines is less than a first preset distance or less than a second preset distance. If the distance between the two coke oven mobile machines is detected to be less than the first preset distance, the two coke oven mobile machines are controlled to decelerate; if the distance between the two coke oven mobile machines is detected to be less than the second preset distance, the two coke oven mobile machines are controlled to brake. This effectively detects the possibility of collision between at least two coke oven mobile machines, improving the safety of multiple coke oven mobile machines.

[0054] To address the shortcomings of existing technologies, this disclosure also provides a method for preventing collisions of mobile coke oven machinery. This method can receive the movement position of the mobile coke oven machinery in real time without contact, can detect potential collision risks in real time, and has strong adaptability to the environment, thereby improving the stability and timeliness of collision prevention for mobile coke oven machinery. Figure 2 The flowchart of one embodiment of a coke oven moving machinery anti-collision method is shown. The above-described coke oven moving machinery anti-collision method includes the following steps:

[0055] Step 201: Receive in real time the movement position of the coded position recording device, the infrared transceiver information of the infrared anti-collision device, and the limit information of the limit device.

[0056] In this embodiment, the execution entity of the coke oven mobile machinery anti-collision method can be the logic controller in the aforementioned coke oven mobile machinery anti-collision system. The coded position recording device includes: an encoder installed on the rollers of the coke oven mobile machinery, the rollers cooperating with a fixed track; the infrared anti-collision device includes: a reflector and an infrared transceiver on the mechanical body of the coke oven mobile machinery, the infrared transceiver being used to emit infrared light to the reflector and receive the emitted signal from the reflector, and to send infrared transmission and reception information; the limit device is installed at the limit position of the coke oven mobile machinery, and is used to record the limit information when the coke oven mobile machinery moves to the limit position.

[0057] Step 202: Based on the moving position, infrared transceiver information, and limit information, control the coke oven moving machinery to decelerate or brake.

[0058] In this embodiment, the moving position, infrared transmission and reception information, and limit information are detected in real time. When either the moving position or the infrared transmission and reception information indicates that the coke oven moving machinery needs to be decelerated, the coke oven moving machinery is directly controlled to decelerate. When the limit information indicates that the limit target has been reached, or the moving position indicates that it has entered the braking position range, or the infrared transmission and reception information indicates that there is a risk of collision with other moving machinery, the coke oven moving machinery is controlled to brake.

[0059] In this embodiment, the system analyzes the received movement position, infrared transceiver information, and limit information. If the limit information indicates that the coke oven moving machinery has reached the limit target, i.e., entered the preset braking range, or if the information is limit information indicating that the machinery has reached the limit position on the track, then the system will immediately trigger the braking mechanism to control the coke oven moving machinery to brake. This measure aims to ensure that the coke oven moving machinery can stop in time when approaching a dangerous area or reaching the end of the track, thereby effectively avoiding collision accidents and ensuring the safety of equipment and operators.

[0060] The anti-collision method for coke oven mobile machinery disclosed herein firstly receives, in real time, the movement position of the coded position recording device, the infrared transceiver information of the infrared anti-collision device, and the limit information of the limit device; secondly, based on the movement position, infrared transceiver information, and limit information, the method controls the deceleration or braking of the coke oven mobile machinery. Thus, by comprehensively utilizing the movement position, infrared transceiver information, and limit information, the operating status of the coke oven mobile machinery can be more comprehensively perceived, enabling more accurate control decisions, effectively preventing collision accidents, improving production efficiency and safety, and enhancing the stability and timeliness of anti-collision measures for the coke oven mobile machinery.

[0061] In some optional implementations of this disclosure, controlling the deceleration or braking of the coke oven mobile machinery based on the movement position, infrared transceiver information, and limit information includes: receiving mode selection information; in response to detecting that the mode selection information indicates the current mode is manual selection mode, blocking the movement position and infrared transceiver information; controlling the deceleration or braking of the coke oven mobile machinery based on the limit information and driver control information; in response to detecting that the mode selection information indicates the current mode is non-manual selection mode, the limit information indicates that the limit target has not been reached, and the infrared transceiver information indicates that there are no other coke oven mobile machinery, based on the movement position, detecting whether the distance between the coke oven mobile machinery and the preset target is less than a first preset distance or less than a second preset distance, wherein the second preset distance is less than the first preset distance; in response to detecting that the distance between the coke oven mobile machinery and the preset target is less than the first preset distance, controlling the coke oven mobile machinery to decelerate; in response to detecting that the distance between the coke oven mobile machinery and the preset target is less than the second preset distance, controlling the coke oven mobile machinery to brake.

[0062] In this embodiment, the modular collision avoidance system offers three selectable modes: manual mode, automatic mode, and unmanned operation mode. The automatic and unmanned operation modes are non-manual selection modes.

[0063] In this embodiment, when manual mode is selected, the driver primarily controls the movement of the coke oven mobile machinery. The driver can only send control information via the industrial control computer to control the distance between the two coke oven mobile machines. The deceleration and stopping of the coke oven mobile machinery are also controlled by the driver's control information. In this case, the coded position recording device and the infrared anti-collision device do not participate in the control. Regarding the relationship between the coke oven mobile machinery and the ground: if the driver makes an operational error and the coke oven mobile machinery exceeds its normal driving range, the ground's limit device will be triggered. This will de-energize the coke oven mobile machinery control circuit, reset the inverter output to zero, forcibly close the brakes, and the mechanical support of the limit device will provide a final layer of protection.

[0064] Between two mobile coke oven machines: If the driver makes an operational error, the limit device between the two mobile coke oven machines will be triggered, and both mobile coke oven machines will stop urgently at the same time. The mechanical support of the limit device will provide the last layer of protection.

[0065] In this embodiment, when the automatic mode or the unmanned operation mode (non-manual mode) is selected, the coded position recording device and the infrared anti-collision device will be put into use, and the screen will display the distance between the two coke oven moving machines.

[0066] When the distance between the mobile coke oven machinery and the ground support is less than a first set distance (e.g., 15m), the mobile coke oven machinery begins to decelerate. When the distance is less than a second set distance (e.g., 5m), the mobile coke oven machinery will stop immediately. Once the automatic stop function fails, the mechanical limit switch of the limit device is triggered, the control circuit of the mobile coke oven machinery is de-energized, the frequency converter output is reset to zero, the brake is forcibly closed, and the mechanical support of the limit device will provide a final layer of protection.

[0067] Between two mobile coke oven machines: When the distance between the two mobile coke oven machines is less than the first set distance (meters), both machines begin to decelerate. When the distance is less than the second set distance, both machines will stop immediately. If the automatic stop function fails, the ground mechanical limit switch of the limit device will be triggered, the control circuit of the two mobile coke oven machines will be de-energized, the frequency converter output will be reset to zero, the brakes will be forcibly closed, and the mechanical supports will provide a final layer of protection.

[0068] In this optional implementation, the method further includes a step of receiving mode selection information. When the mode selection information indicates that the current mode is manual, the system will stop receiving the movement position and infrared transceiver information of the coke oven mobile machinery. However, even in manual mode, it will still respond to received limit information. Once limit information is received, indicating that the coke oven mobile machinery has reached the limit position on the track, the system will immediately control the coke oven mobile machinery to brake to ensure safety. This design allows for a response to critical limit information even in manual operation mode, thus ensuring operational flexibility without sacrificing safety.

[0069] In some optional implementations of this disclosure, there are at least two coke oven mobile machines; the control of deceleration or braking of the coke oven mobile machines based on movement position, infrared transceiver information, and limit information includes: in response to detecting that the mode selection information indicates the current mode is a non-manual selection mode, the limit information indicates that the limit target has not been reached, and the movement position indicates that the distance between the coke oven mobile machine and the preset target is greater than a first set distance, based on the infrared transceiver information, detecting whether the distance between any two of the at least two coke oven mobile machines is less than the first set distance or less than a second set distance; in response to detecting that the distance between the two coke oven mobile machines is less than the first set distance, controlling the two coke oven mobile machines to decelerate; in response to detecting that the distance between the two coke oven mobile machines is less than the second set distance, controlling the two coke oven mobile machines to brake.

[0070] In this optional implementation, at least two coke oven mobile machines are involved. First, the mechanical distance between any two coke oven mobile machines is calculated based on the braking or limit information of each machine. Then, braking control is implemented on these two machines based on the determined mechanical distance. This process aims to ensure the safe operation of the coke oven mobile machines by effectively avoiding collisions through precise distance monitoring and corresponding braking control in scenarios involving multiple machines.
