[0020] First, the applicable application scenarios of this application will be introduced. The embodiments provided in this application are applicable to the field of steelmaking production technology.
[0021] Currently, there are high safety risks in the process of adding molten iron and scrap steel during the production of steelmaking converters. High-temperature molten iron, molten steel and slag may splash, and if personnel accidentally enter the danger zone when equipment such as overhead cranes are operating near the furnace mouth, they are very likely to be splashed and suffer burns and other safety accidents.
[0022] However, safety protection in the converter operation area relies heavily on manual supervision and simple warning signs, which have limited protective effects and make it difficult to achieve real-time monitoring and automatic control, resulting in low efficiency of manual inspection.
[0023] Based on this, the embodiments of this application provide a method, device and electronic equipment for determining safety protection in converter operations. The embodiments provided by this application solve the technical problems in the prior art that the operator is easily burned by splashing, the protective effect is limited, it is difficult to achieve real-time monitoring and automatic control, and the manual inspection efficiency is low. The embodiments provided by this application reduce the probability of burns caused by molten iron splashing, realize real-time monitoring and automatic control of the target area, and improve the inspection efficiency.
[0024] Figure 1 A flowchart illustrating a method for determining safety protection in converter operations, as provided in an embodiment of this application, is shown. Figure 1 As shown, the method for determining safety protection measures for converter operations includes the following steps: S101. Obtain the light curtain monitoring signal of the converter to be tested within the target area, wherein the target area is used to characterize the dangerous area where safety accidents are likely to occur when the target operator enters the converter operation area.
[0025] In this step, the embodiments provided in this application, when aiming to provide safety protection for the converter operation process, first need to monitor the light curtain monitoring signal in the dangerous area where safety accidents are likely to occur when the target operator enters the converter operation area in real time.
[0026] It should be noted that the light curtain monitoring signal obtained in the embodiments provided in this application is acquired by light curtains set on both sides of the converter to be tested. The light curtains in the embodiments provided in this application need to be set within the preset angles on the left and right sides of the converter to be tested when the furnace mouth of the converter to be tested is facing the direction of adding molten iron, that is, the two light curtains are set within the target limiting angles of the furnace mouth of the converter to be tested.
[0027] It is understood that the light curtain in the embodiments provided in this application works on the basis of an optical occlusion sensing mechanism.
[0028] In the embodiments provided in this application, the light curtain for collecting light curtain monitoring signals is composed of a transmitter and a receiver. The transmitter emits multiple beams of parallel infrared light, which are the light curtain monitoring signals. The receiver is responsible for receiving these beams to achieve real-time monitoring of the status of all equipment and target personnel within the target area. The light curtain can cover the dangerous areas that target personnel may accidentally enter during the process of adding molten iron and scrap steel in the converter to be detected.
[0029] For example, the embodiments provided in this application determine the target area in the following manner: Obtain the tilt angle of the furnace opening of the converter to be tested when it is aligned with the corresponding ladle; based on the tilt angle, determine the corresponding target restriction angles to the left and right of the furnace opening, wherein the target restriction angle is used to characterize the danger angle threshold at which safety accidents are likely to occur when the target operator enters the converter operation area; based on the target restriction angle, determine the target area.
[0030] In the above-described embodiments, the present application first obtains the tilt angle of the converter opening when it is aligned with the ladle, and then, based on the tilt angle, determines the dangerous area that the target operator may face when entering the converter operation area, and then identifies the dangerous area as the target area where safety accidents are likely to occur.
[0031] Here is a schematic diagram showing the converter being aligned with the ladle. Figure 2 and Figure 3 As shown, Figure 2 This illustration shows one of the structural diagrams of the connection between the converter to be tested and the ladle in a method for determining safety protection of converter operation provided in an embodiment of this application. Figure 3 This illustration shows a second schematic diagram of the connection between the converter to be tested and the ladle in a method for determining safety protection during converter operations provided in this application. (See attached diagram.) Figure 2 and Figure 3 As shown, when the furnace opening of the converter to be tested is tilted and aligned with the ladle, a certain target limiting angle is formed between the furnace opening of the converter to be tested and the two light curtains on the left and right.
[0032] In this application, the target limiting angle in the embodiments can be customized and used according to different application scenarios and usage conditions. The target limiting angle in the embodiments provided in this application can be specifically set to 120 degrees, which solves the problem that traditional light curtains cannot collect light curtain monitoring signals in the critical danger area of the 120-degree angle between the left and right sides of the furnace opening, thereby enhancing the detection efficiency and reducing safety accidents such as burns caused by splashing.
[0033] S102. Based on the light curtain monitoring signal, determine whether the target personnel have entered the target area.
[0034] In this step, in the embodiments provided in this application, once a target worker or other object enters the target area, the light curtain monitoring signal will be partially blocked, which will cause the received light curtain monitoring signal to change. Therefore, it is necessary to obtain the light curtain monitoring signal in the target area in real time to determine whether a target worker has entered the target area.
[0035] It should be noted that when no personnel or other objects enter the target area, the receiver of the light curtain can receive all the light emitted by the transmitters. At this time, the light curtain is in normal working condition, and the lifting and lowering operation of the overhead crane of the converter to be tested, the tilting operation of the converter to be tested, and the feeding operation of the converter to be tested are all in normal working condition.
[0036] For example, determining whether a target worker has entered a target area based on light curtain monitoring signals includes: Based on the light curtain monitoring signal, it is determined whether there are obstructions in the target area; if there are, it is determined that the target personnel have entered the target area; if there are no obstructions, it is determined that the target personnel have not entered the target area.
[0037] It is understood that, after the monitoring signal is determined, the embodiments provided in this application will determine whether the target worker has entered the target area based on whether the light curtain monitoring signal is blocked. If the light curtain monitoring signal is blocked, the target worker is determined to have entered the target area; if the light curtain monitoring signal is not blocked, the target worker is determined not to have entered the target area.
[0038] S103. If the target operator enters the target area, an audible and visual alarm is triggered, and the lifting, tilting, and feeding operations of the overhead crane of the converter under test are controlled simultaneously.
[0039] In this step, the embodiment provided in this application, after determining that the target operator has entered the target area, transmits the light curtain monitoring signal to the alarm device connected to it, thereby triggering an audible and visual alarm to remind the target operator on site to pay attention to safety. At the same time, it controls the operation of the lifting equipment on the crane of the converter to be tested, the tilting operation of the converter to be tested, and the feeding operation of the converter to be tested.
[0040] For example, controlling the lifting and lowering operation of the overhead crane of the converter under test includes: The crane controlling the external converter under test can prevent the large hook assembly from descending, or prevent the large hook assembly from rising, or prevent the small hook assembly from rising, or control the small hook assembly from descending.
[0041] It should be noted that, in the embodiments provided in this application, after determining that the target worker has entered the target area, the forward and reverse rotation and speed of the motor will be controlled to realize the raising and lowering actions of the large hook and the small hook. For example, the overhead crane of the externally controlled converter to be tested will be controlled to prevent the large hook assembly from descending, or the overhead crane of the externally controlled converter to be tested will be controlled to prevent the large hook assembly from rising, so as to prevent heavy objects such as molten iron ladles and scrap steel ladles from continuing to fall and causing danger; or the overhead crane of the externally controlled converter to be tested will be controlled to prevent the small hook assembly from rising, so as to avoid the small hook driving related parts to rise and threatening the target worker; or the overhead crane of the externally controlled converter to be tested will be controlled to control the small hook assembly to descend, thereby reducing the process of the target worker being in danger in the target area.
[0042] For example, controlling the tilting operation of the converter under test includes: controlling the converter under test to prevent it from tilting further to a horizontal or vertical position.
[0043] It should be noted that, in the embodiments provided in this application, once the target operator enters the target area, an audible and visual alarm will be activated immediately, followed by a conspicuous sound and light warning to remind the target operator to stay away from the danger zone and prompt relevant operators to take countermeasures. The alarm will also control the converter to be tested to prevent it from tilting further to a horizontal position, thus preventing the furnace opening from tilting too much and causing the high-temperature material to splash more widely, thereby increasing the safety risk.
[0044] For example, controlling the charging operation of the converter under test includes controlling the converter under test to stop the operation of adding molten iron or scrap steel into the ladle.
[0045] It should be noted that, in the embodiments provided in this application, after determining that the target operator has entered the target area, the converter to be tested will be controlled to stop adding molten iron or scrap steel to the ladle, so as to stop the adding of molten iron or scrap steel, interrupt the dangerous operation process, and continue until the danger is eliminated.
[0046] For example, after triggering an audible and visual alarm when the target operator enters the target area, and simultaneously controlling the lifting, tilting, and feeding operations of the overhead crane, the converter under test, and the converter under test, the method further includes: determining whether the target operator has left the target area based on the light curtain monitoring signal; if the target operator leaves the target area, controlling the restoration of normal operation of the overhead crane and the converter under test.
[0047] It should be noted that, in the embodiments provided in this application, after the target operator enters the target area and adjusts the operation of the overhead crane and the converter to be inspected, the system will re-determine whether the target operator has left the target area based on the light curtain monitoring signal, and after determining that the target operator has left the target area, it will control the normal operation of the overhead crane and the converter to be inspected to resume.
[0048] Compared with the prior art, the method for determining the safety protection of converter operations provided in this application obtains the light curtain monitoring signal of the converter to be inspected within the target area, and then determines whether the target operator has entered the target area based on the light curtain monitoring signal. When the target operator enters the target area, an audible and visual alarm is triggered, and the lifting operation of the overhead crane, the tilting operation, and the charging operation of the converter to be inspected are controlled simultaneously. The method provided in this application reduces the probability of safety accidents such as burns caused by molten iron splashing, realizes real-time monitoring and automatic control of the target area, and improves the efficiency of inspection.
[0049] Figure 4 This is a structural block diagram of a device for determining safety protection in converter operations, provided as an embodiment of this application. Figure 4 As shown, the safety protection device 400 for converter operation includes: The acquisition module 410 is used to acquire the light curtain monitoring signal of the converter to be detected within the target area, wherein the target area is used to characterize the dangerous area where safety accidents are likely to occur when the target operator enters the converter operation area.
[0050] The first determining module 420 is used to determine whether the target worker has entered the target area based on the monitoring signal.
[0051] The first control module 430 is used to trigger an audible and visual alarm if the target operator enters the target area, and simultaneously control the lifting and lowering operation of the crane of the converter under test, the tilting operation of the converter under test, and the feeding operation of the converter under test.
[0052] The second determining module 440 is used to determine whether the target worker has left the target area based on the light curtain monitoring signal.
[0053] The second control module 450 is used to restore the normal operation of the overhead crane and the converter under inspection if the target operator leaves the target area.
[0054] For example, in the acquisition module 410, the target area is determined in the following way: Obtain the tilt angle of the furnace opening of the converter to be tested when it is aligned with the corresponding ladle.
[0055] Based on the tilt angle, the corresponding target restriction angles on the left and right sides of the furnace opening are determined. The target restriction angle is used to characterize the danger angle threshold at which safety accidents are likely to occur when the target operator enters the converter operation area.
[0056] The target area is determined based on the target's limiting angle.
[0057] For example, the second determining module 440 is specifically used for: Based on the light curtain monitoring signal, it is determined whether there are obstructions in the target area.
[0058] If it exists, then the target personnel are confirmed to have entered the target area.
[0059] If not, it is determined that the target personnel have not entered the target area.
[0060] For example, controlling the lifting and lowering operation of the overhead crane of the converter under test includes: The crane controlling the external converter under test can prevent the large hook assembly from descending, or prevent the large hook assembly from rising, or prevent the small hook assembly from rising, or control the small hook assembly from descending.
[0061] For example, controlling the tilting operation of the converter under test includes: The converter under test must not be tilted further into a horizontal or vertical position.
[0062] For example, controlling the feeding operation of the converter to be tested includes: Control the converter under test to stop adding molten iron or scrap steel to the ladle.
[0063] Compared with the prior art, the converter operation safety protection device provided in this application obtains the light curtain monitoring signal of the converter to be inspected within the target area, and then determines whether the target operator has entered the target area based on the light curtain monitoring signal. When the target operator enters the target area, an audible and visual alarm is triggered, and the lifting operation of the crane, the tilting operation, and the charging operation of the converter to be inspected are controlled simultaneously. The embodiment of this application reduces the probability of safety accidents such as burns caused by molten iron splashing, realizes real-time monitoring and automatic control of the target area, and improves the efficiency of inspection.
