[0052] In the above figures: 1. On-vehicle data acquisition and control device; 2. Data base station. Detailed implementation manners

[0053] By providing a method for monitoring a torpedo car in an embodiment of the present application, the technical problem that the torpedo car is prone to tipping failures in the prior art is solved.

[0054] The technical solution of the embodiment of the present application for solving the above technical problem has the following general idea:

[0055] An embodiment of the present application provides a method for monitoring a torpedo car, including: the on-vehicle data acquisition and control device of the torpedo car receives and responds to a first status signal that the torpedo car has not reached the ladle turntable, performs a spot check on the torpedo car to obtain actual spot check data; the on-vehicle data acquisition and control device receives and responds to a second status signal that the torpedo car has reached the ladle turntable, establishes communication with the data base station of the ladle turntable, and sends the actual spot check data to the data base station; the data base station responds to a spot check normal signal that the actual spot check data meets a preset spot check standard, generates a tipping signal for instructing the torpedo car to perform a tipping operation; the on-vehicle data acquisition and control device receives and responds to the tipping signal, monitors the actual tipping data of the torpedo car, and sends the actual tipping data to the data base station; in the case where the data base station determines that the actual tipping data does not meet the preset tipping standard, a first alarm signal for prompting a tipping failure is generated.

[0056] It can be seen that by setting up an on-vehicle data acquisition and control device on the torpedo car, and completing the spot check using the on-vehicle data acquisition and control device before the torpedo car enters the ladle turntable station, the continuity of production is ensured, and the controllability of the torpedo car in the high-temperature environment when entering the ladle turntable station is improved; the actual spot check data collected by the on-vehicle data acquisition and control device is obtained in an offline state, which can reduce the noise interference of wireless communication and improve the accuracy of the data. During the tipping operation, the actual tipping data is monitored through the on-vehicle data acquisition and control device, and the actual tipping data is transmitted to the data base station. The data base station judges whether it is in a safe operating state. In the case of a tipping failure, a reminder or alarm is issued in a timely manner, thereby reducing the risk of out-of-control caused by sudden equipment failures, blocking the deterioration of the failure in a timely manner, reducing the possibility of molten iron splashing or mechanical damage, and improving the safety of the production process.

[0057] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0058] First of all, it should be noted that the term "and / or" appearing in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the front and rear associated objects.

[0059] As the core equipment for transporting molten iron in metallurgical enterprises, after long-term operation, the torpedo car frequently experiences tipping failures due to the deterioration of its technical state, mainly manifested as problems such as no tipping action, abnormal current overlimit, and increased mechanical vibration, resulting in failures such as motor burnout, chain breakage, and damage to the reduction gearbox gears. According to the statistics of a certain base, the cumulative failure handling time in two years was as high as 96 hours, seriously affecting production safety and efficiency.

[0060] Its equipment management adopts a mode of segmented responsibility between the steelmaking plant and the transportation department. The steelmaking plant is in charge of operation-end equipment such as power plugs and control consoles; the transportation department manages execution-end equipment such as motors and reduction gearboxes. The cooperation between the two parties' equipment is insufficient and the responsibilities overlap. Coupled with factors such as the accumulation of residual iron and human operation errors during the tipping operation, the failure risk is further exacerbated.

[0061] The harsh environment of high-temperature radiation and metal dust in the ladle turntable station makes it difficult to monitor the operating state of the equipment in real time. The traditional static spot check relies on manual experience and adopts a combination of five-sense observation and instrument sampling inspection, which has problems such as a high missed inspection rate (limited by insufficient time and environmental interference), strong subjectivity of results (mainly qualitative judgment), and weak data support, resulting in large deviations in fault analysis and inaccurate rectification measures, and unable to effectively warn and block the deterioration of faults.

[0062] To solve the above problems, an embodiment of the present application provides a monitoring method for a torpedo car, which is matched with a torpedo car provided by an embodiment of the present application.

[0063] First, an embodiment of the present application will first describe the torpedo car and the ladle turret. As Figure 1 shown, it is a structural schematic diagram of a torpedo car and a ladle turret provided by an embodiment of the present application. The area on the left side of the dotted line represents the safe area outside the ladle turret. The torpedo car travels from the safe area to the ladle turret to perform the task of transporting molten iron. The area on the right side of the dotted line represents the area inside the ladle turret. The torpedo car performs a tilting operation inside the ladle turret area to pour the molten iron into the collection tank inside the ladle turret.

[0064] A vehicle-mounted data acquisition and control device 1 is provided on the torpedo car, and a data base station 2 is provided inside the ladle turret. The vehicle-mounted data acquisition and control device 1 can establish communication with the data base station 2 and transmit data bidirectionally.

[0065] As Figure 2 shown, it is a structural schematic diagram of a vehicle-mounted data acquisition and control device 1 provided by an embodiment of the present application. The vehicle-mounted data acquisition and control device 1 includes a data acquisition unit 11, a communication unit 12, a video unit 13, a circuit switching unit 14, a battery monitoring unit 15, and a central control unit 16 that are connected to each other.

[0066] It should be noted that the connection here can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0067] Among them, the data acquisition unit 11 is used to monitor the actual inspection data and / or the actual tilting data. In some embodiments, two data acquisition units 11 are provided, and each data acquisition unit 11 only monitors the data corresponding to one working process to respectively monitor the actual inspection data and the actual tilting data. In the subsequent embodiments of the present application, an example in which one data acquisition unit 11 monitors both the actual inspection data and the actual tilting data will be continued to be described.

[0068] The data acquisition unit 11 includes a temperature monitoring component 111, a resistance monitoring component 112, a voltage monitoring component 113, a current monitoring component 114, and an angle monitoring component 115.

[0069] The temperature monitoring component 111 is used to monitor the ambient temperature of the torpedo car.

[0070] The resistance monitoring component 112 is used to monitor at least one of the inter-phase resistance data of the motor stator, the inter-phase resistance data of the motor rotor, the brake resistance data, the insulation resistance data of the motor stator, the insulation resistance data of the motor rotor, and the insulation resistance data of the brake.

[0071] The voltage monitoring component 113 is used to monitor at least one of the stator voltage data of the motor, the rotor voltage data of the motor, and the brake voltage data.

[0072] The current monitoring component 114 is used to monitor at least one of the stator current data of the motor, the rotor current data of the motor, and the brake current data.

[0073] The angle monitoring component 115 is used to monitor the tipping angle data of the tank body.

[0074] It should be noted that the "motor" in the above data types refers to the tipping drive motor, usually a three-phase asynchronous motor. The "current" in the above data types refers to three-phase current, and the "voltage" in the above data types refers to three-phase voltage.

[0075] Preferably, the data acquisition unit 11 further includes a component for processing digital quantities, a component for processing analog quantities, and a communication component (such as an RS485 communication component) for internal data communication.

[0076] The vehicle-mounted data acquisition control device 1 further includes a communication unit 12, a video unit 13, a circuit switching unit 14, a battery monitoring unit 15, and a central control unit 16.

[0077] The communication unit 12 is used to establish communication with the data base station 2 and send the actual inspection data and actual tipping data monitored by the data acquisition unit 11 to the data base station 2. The communication unit 12 includes a wireless network component 121, and the wireless network component 121 establishes communication with the data base station 2 through the industrial WI FI set in the tank emptying station.

[0078] The video unit 13 is responsible for video recording at least one of the tipping motor, the brake, the rotating drive chain, and the tipping bearing angle, and sending the video data stream to the data base station 2 through the communication unit 12. The data base station 2 can present the processed video stream data on the human-machine interaction interface for the operator to view. The video unit 13 includes an image acquisition component 131 for acquiring at least one of the tipping bearing image data and the tank body tipping angle data.

[0079] The circuit switching unit 14 is responsible for the function switching of the vehicle-mounted data acquisition control device 1, optimizing the compatibility between each unit, and improving the energy utilization rate. The circuit switching unit 14 includes a switching circuit component 141 for switching the working lines of each unit.

[0080] The battery monitoring unit 15 supplies power to the on-vehicle data acquisition and control device 1, including a battery charging component 151, a battery discharging component 152, and a battery component 153. It can achieve the switching between charging and discharging states, complete the rapid charging of the battery, and support the simultaneous power supply to the on-vehicle data acquisition and control device 1 by the battery and an external power source. Preferably, the battery component 153 includes a lead-acid battery to improve the stability of power supply.

[0081] The central control unit 16 is used to cooperate in controlling each unit, establish and control related tasks such as inspection, data monitoring, and data transmission. When the torpedo car is outside the pouring station, the central control unit 16 can temporarily store the actual inspection data. The central control unit 16 can also preprocess (such as data cleaning) the actual inspection data and / or actual tipping data monitored by the data acquisition unit 11. In addition, the central control unit 16 can also implement functions such as time synchronization, heartbeat, timing, communication, model rules, value conversion, data caching, data scheduling, and alarm control.

[0082] To adapt to the influence of working environments such as high temperature, high metal dust, and high electromagnetic radiation outside and inside the pouring station, a protective shell is provided outside the on-vehicle data acquisition and control device 1, preferably made of stainless steel conforming to the IP67 protection level.

[0083] After the above description of the torpedo car and the data base station 2, the embodiments of the present application will further describe a torpedo car monitoring method provided as follows.

[0084] As Figure 3 shown, it is a schematic flowchart of a torpedo car monitoring method provided by the embodiments of the present application, including step S1-step S5.

[0085] Step S1, the on-vehicle data acquisition and control device 1 of the torpedo car receives and responds to the first status signal that the torpedo car has not reached the pouring station, inspects the torpedo car, and obtains actual inspection data;

[0086] Step S2, the on-vehicle data acquisition and control device 11 receives and responds to the second status signal that the torpedo car has reached the pouring station, establishes communication with the data base station 2 of the pouring station, and sends the actual inspection data to the data base station 2;

[0087] Step S3, the data base station 2 responds to the inspection normal signal that the actual inspection data conforms to the preset inspection standard, and generates a tipping signal for instructing the torpedo car to perform a tipping operation;

[0088] Step S4, the on-vehicle data acquisition and control device 1 receives and responds to the tipping signal, monitors the actual tipping data of the torpedo car, and sends the actual tipping data to the data base station 2;

[0089] Step S5, when the data base station 2 determines that the actual tipping data does not meet the preset tipping standard, a first alarm signal for prompting a tipping fault is generated.

[0090] Regarding step S1, the on-vehicle data acquisition and control device 1 of the torpedo car receives and responds to the first status signal that the torpedo car has not reached the ladle tipping station, performs a spot check on the torpedo car, and obtains the actual spot check data.

[0091] The torpedo car not reaching the ladle tipping station means that the torpedo car is in a safe area outside the ladle tipping station, and at this time the torpedo car is performing a transportation task. Since there are strong electromagnetic interference sources such as high-power motors and frequency converters around the ladle tipping station, it is easy to affect the accuracy of the spot check process. At the same time, in order to ensure the continuity of production and improve the controllability of the torpedo car in the high-temperature environment when entering the ladle tipping station, it is necessary to complete the spot check outside the ladle tipping station to obtain the actual spot check data.

[0092] The first status signal includes at least one signal type among electrical signals, acoustic signals, optical signals, and mechanical signals.

[0093] It should be noted that the spot check process is completed in an offline state. That is, when the torpedo car is outside the ladle tipping station (for example, Figure 1 at position A), the on-vehicle data acquisition and control device 1 is not connected to the industrial WI FI of the ladle tipping station and has not established communication with the data base station 2. Offline spot check can reduce the noise interference of wireless communication on the monitoring process of the data acquisition unit and improve the accuracy of the actual spot check data.

[0094] Furthermore, the actual spot check data includes at least one of the following: motor stator phase-to-phase resistance data, motor rotor phase-to-phase resistance data, brake resistance data, motor stator insulation resistance data, motor rotor insulation resistance data, and brake insulation resistance data.

[0095] Regarding step S2, the on-vehicle data acquisition and control device 1 receives and responds to the second status signal that the torpedo car has reached the ladle tipping station, establishes communication with the data base station 2 of the ladle tipping station, and sends the actual spot check data to the data base station 2.

[0096] The torpedo car reaching the ladle tipping station means that the torpedo car reaches the area inside the ladle tipping station represented by the right side of the dotted line in Figure 1 (for example, position B), and the communication module of the on-vehicle data acquisition and control device 1 establishes communication with the data base station 2 through the industrial WI FI inside the ladle tipping station.

[0097] The second status signal includes at least one signal type among electrical signals, acoustic signals, optical signals, and mechanical signals.

[0098] Preferably, the data base station 2 can also provide a human-machine interaction interface to display the actual spot check data.

[0099] Regarding step S3, the data base station 2 generates a tipping signal for instructing the torpedo car to perform a tipping operation in response to a normal inspection signal indicating that the actual inspection data meets the preset inspection standard, including steps S31 - S33.

[0100] Step S31, the data base station 2 determines whether the actual inspection data meets the preset inspection standard;

[0101] Step S32, when the data base station 2 determines that the actual inspection data meets the preset inspection standard, a normal inspection signal is generated;

[0102] Step S33, the data base station 2 generates a tipping signal in response to the normal inspection signal.

[0103] Regarding step S31, the data base station 2 determines whether the actual inspection data meets the preset inspection standard.

[0104] The preset inspection standard is a pre - set detection specification used to guide the judgment of whether each device on the torpedo car is in a safe operating state.

[0105] Furthermore, in the case where at least one torpedo car performs at least one transportation task, step S31 further includes:

[0106] Step S311, the data base station 2 stores the historical inspection data corresponding to at least one torpedo car and / or at least one transportation task;

[0107] Step S312, the data base station 2 determines an inspection standard model based on the stored historical inspection data, and corrects the preset inspection standard according to the inspection standard model.

[0108] Regarding steps S311 and S312, the data base station 2 determines the inspection standard model through related model - building steps such as pre - processing, feature extraction, model selection, model training, model evaluation, and model optimization of the historical inspection data, and then corrects the preset inspection standard according to the inspection standard model, thereby improving the accuracy and adaptability of the preset inspection standard and enhancing the ability to judge the safe operating state.

[0109] Regarding step S32, when the data base station 2 determines that the actual inspection data meets the preset inspection standard, a normal inspection signal is generated.

[0110] The normal inspection signal includes at least one of electrical signal, acoustic signal, optical signal, and mechanical signal.

[0111] In the case where the data base station 2 determines that the actual inspection data does not meet the preset inspection standard, the method further includes steps S321 - S322.

[0112] Step S321, the data base station 2 generates a second alarm signal for prompting troubleshooting of the torpedo car.

[0113] Step S322, the data base station 2 receives and responds to the normal inspection normal signal indicating that the troubleshooting result is normal, and corrects the preset inspection standard.

[0114] Regarding step S321, for troubleshooting, other external detection devices such as a multimeter, a megohmmeter, and a vibration meter can be used to check the relevant equipment with abnormal actual inspection data, and further determine whether the torpedo car has a fault. The second alarm signal includes at least one of an electrical signal, a sound signal, an optical signal, and a mechanical signal.

[0115] Regarding step S322, the correction of the preset inspection standard can be achieved by changing the threshold value of the preset inspection standard.

[0116] Regarding step S4, the on-vehicle data acquisition and control device 1 receives and responds to the tipping signal, monitors the actual tipping data of the torpedo car, and sends the actual tipping data to the data base station 2.

[0117] The tipping signal includes at least one of an electrical signal, a sound signal, an optical signal, and a mechanical signal.

[0118] It should be noted that the monitoring of the actual tipping data is completed in the state of communicating with the data base station 2 to update the actual tipping data to the data base station 2 in real time.

[0119] The actual tipping data includes at least one of tipping bearing image data, motor stator voltage data, motor stator current data, motor rotor voltage data, motor rotor current data, brake voltage data, brake current data, and tank tipping angle data.

[0120] Regarding step S5, when the data base station 2 determines that the actual tipping data does not meet the preset tipping standard, a first alarm signal for prompting a tipping fault is generated.

[0121] The preset tipping standard is the control parameters and safety thresholds that need to be followed during the tipping operation (molten iron pouring operation), which is used to achieve the controllability of the tipping operation and reduce the possibility of tipping faults such as mechanical overload or molten iron splashing.

[0122] Furthermore, when at least one torpedo car performs at least one transportation task, step S5 further includes steps S511 - S512.

[0123] Step S511, the data base station 2 stores the historical tipping data corresponding to at least one torpedo car and / or at least one transportation task;

[0124] Step S512: The data base station 2 determines a tipping standard model based on the stored historical tipping data, and corrects the preset tipping standard according to the tipping standard model.

[0125] Regarding step S511 and step S512, the data base station 2 determines the tipping standard model through relevant model establishment steps such as preprocessing, feature extraction, model selection, model training, model evaluation, and model optimization of the historical tipping data, and then corrects the preset tipping standard according to the tipping standard model, thereby improving the accuracy and adaptability of the preset tipping standard and enhancing the ability to judge the safe operating state.

[0126] Furthermore, regarding step S5, the data base station 2 determines whether the actual tipping data conforms to the preset tipping standard, including step S521 - step S522.

[0127] Step S521: The data base station 2 determines the tipping trend corresponding to the current tipping operation according to the tipping standard model and the actual tipping data.

[0128] Step S522: The data base station 2 determines whether it conforms to the preset tipping standard according to the tipping trend.

[0129] Regarding step S521 - step S522, the tipping trend is the state evolution direction of the current tipping operation, including the prediction of the future development state, such as the trend of the tipping angle of the ladle and the trends of resistance and current changes.

[0130] In step S5, after the data base station 2 generates a first alarm signal indicating a tipping fault when it determines that the actual tipping data does not conform to the preset tipping standard, the method further includes:

[0131] The data base station 2 controls the mixer car to stop the tipping operation in response to the first alarm signal.

[0132] In summary, the embodiment of the present application provides a method for monitoring a mixer car, including: the on-vehicle data acquisition control device of the mixer car receives and responds to the first state signal that the mixer car has not reached the pouring station, performs a spot check on the mixer car to obtain actual spot check data; the on-vehicle data acquisition control device receives and responds to the second state signal that the mixer car has reached the pouring station, establishes communication with the data base station of the pouring station, and sends the actual spot check data to the data base station; the data base station generates a tipping signal for instructing the mixer car to perform a tipping operation in response to the spot check normal signal that the actual spot check data conforms to the preset spot check standard; the on-vehicle data acquisition control device receives and responds to the tipping signal, monitors the actual tipping data of the mixer car, and sends the actual tipping data to the data base station; when the data base station determines that the actual tipping data does not conform to the preset tipping standard, it generates a first alarm signal indicating a tipping fault.

[0133] It can be seen that by setting up an on-vehicle data acquisition and control device on the torpedo car, and completing the inspection before the torpedo car enters the ladle turntable station using the on-vehicle data acquisition and control device, the continuity of production is ensured, and the controllability of the torpedo car in the high-temperature environment when entering the ladle turntable station is improved; the actual inspection data collected by the on-vehicle data acquisition and control device is obtained in an offline state, which can reduce the noise interference of wireless communication and improve the accuracy of the data. During the tilting operation, the on-vehicle data acquisition and control device monitors the actual tilting data and transmits the actual tilting data to the data base station. The data base station judges whether it is in a safe operating state, and issues a reminder or alarm in a timely manner in the case of a tilting fault, thereby reducing the risk of out-of-control caused by sudden equipment failures, blocking the deterioration of the fault in a timely manner, reducing the possibility of molten iron splashing or mechanical damage, and improving the safety of the production process.
