Description

Technical Field

[0001] This invention relates to the field of hybrid train technology, and more particularly to an electrical room system and control method for the electrical equipment of an unmanned hybrid train. Background Technology

[0002] Molten iron transportation is a crucial part of the steel industry's production process. With the continuous improvement of production levels and changes in market trends, companies must constantly innovate and explore new methods for molten iron transportation, while also continuously improving their scheduling techniques. Currently, domestic molten iron rail transport mainly uses specialized molten iron cars as transport vehicles, primarily of two types: open-top molten iron cars and torpedo-type molten iron cars. Among these, torpedo-type molten iron cars offer significant advantages over open-top molten iron cars in terms of operability, operating speed, and heat preservation performance.

[0003] In the workplace, the railway lines of steel enterprises are complex, characterized by numerous switches, short tracks, multiple reused lines, fixed operating areas, and a large number of special vehicles. This makes transportation scheduling technically much more challenging than that of ordinary railways. Furthermore, as steel enterprises constantly adapt to changing market demands, they must frequently construct and renovate plant buildings and adjust steel production, leading to rapid changes in the plant's railway lines and frequent line modifications. This, in turn, results in complex and variable traffic organization. Therefore, the entire process of molten iron transportation scheduling is extremely complex, and enterprises need to continuously adapt their production conditions and levels according to changes in social and market demands. Despite the complexity of molten iron transportation, its scheduling level has not yet reached a modern, let alone intelligent, level. On-site, molten iron scheduling still relies on the experience of on-site staff for scheduling decisions. Therefore, the workload of operators is extremely heavy, inevitably leading to errors or oversights due to work pressure and on-site conditions, ultimately resulting in low and unstable scheduling efficiency.

[0004] Currently, the level of on-site dispatching in steel enterprises depends heavily on the long-term work experience and on-site adaptability of operators. For example, when production operations are disrupted by malfunctions or unexpected events, preventing operation from following the original schedule, dispatchers must make quick subjective judgments. It's difficult for them to comprehensively consider all on-site transportation operation information, and they lack sufficient time for analysis, calculation, and sound decision-making. If on-site personnel cannot effectively implement emergency measures, the final decision will affect other transportation tasks. For instance, unplanned occupation of tracks or switches can delay other transportation tasks. Furthermore, the iron production process is prone to frequent incidents such as uneven tapping time and quantity, inconsistent iron quality during transportation, untimely iron supply, and damage to transportation equipment. Combined with inherent uncertainties in the iron processing technology, these factors make iron dispatching more challenging than in national railways.

[0005] To address the shortcomings of existing molten iron transportation methods and improve the turnover rate of mixed-rail vehicles, researchers have proposed a method for realizing a permanent magnet direct-drive mixed-rail vehicle and its traction system without altering the main structure of existing mixed-rail vehicles. By employing technologies such as 5G communication, intelligent sensing, unmanned control, and permanent magnet drive, they have developed an autonomous intelligent mixed-rail vehicle (ARIT, Autometic Running Intelligent TPC), which enables the mixed-rail vehicle to operate with its own power, operate unmanned, improve turnover rate, and achieve energy conservation and emission reduction.

[0006] Currently, research teams are primarily focused on developing unmanned systems, with little attention paid to the safety of the electrical room, which is crucial for ensuring the safe and stable operation of the electrical equipment in unmanned mixed-train vehicles. Throughout the entire operational process of an unmanned mixed-train vehicle, it experiences significant temperature variations and complex, ever-changing environments, all of which greatly impact its electrical equipment. Therefore, it is necessary to develop an electrical room that can adapt to the operating conditions of unmanned mixed-train vehicles to guarantee the safe and stable operation of their electrical equipment.

[0048] In this embodiment, the indoor electrical equipment includes a power battery pack 8, a first electrical cabinet 9, a second electrical cabinet 10, and a backup power battery 11; an LED light 17 is installed above the second electrical cabinet 10.

[0049] Specifically, the main body of the electrical room is mainly used to store the power battery pack 8, the first electrical cabinet 9, the second electrical cabinet 10 and the spare power battery 11, to provide power, control and feedback signals for the unmanned hybrid vehicle, and to rationally plan the equipment in the electrical room within the limited space of the main body of the electrical room.

[0050] Specifically, the power battery pack 8 is mainly used to provide power for the unmanned hybrid vehicle. The power battery pack 8 can use rechargeable batteries, ternary lithium batteries, lithium iron phosphate batteries, and also includes oxide solid-state batteries, sulfide solid-state batteries, and polymer solid-state batteries, but ternary lithium batteries and lithium iron phosphate batteries are preferred. The capacity of the power battery pack 8 should meet the needs of the unmanned hybrid vehicle for continuous operation of 1-168 hours, but preferably within the 12-24 hour range. Based on the energy density calculations of existing ternary lithium batteries and lithium iron phosphate batteries, the length of the power battery pack 8... The dimensions of (a1), width (b1), and height (h1) should be 0.5m≤a1≤3.5m, 0.2m≤b1≤10m, and 0.5m≤h1≤4.5m. Based on the standard loading capacity of 300-400 tons for unmanned hybrid trains, the more suitable dimensions are 2m≤a1≤3.3m, 0.5m≤b1≤2m, and 1m≤h1≤2m. Other suitable dimensions include 0.2m≤a1≤1.0m, 0.1m≤b1≤0.5m, and 0.2m≤h1≤1m.

[0051] Specifically, the first electrical cabinet 9 is mainly used to distribute power to the power battery pack 8. It belongs to the category of high-voltage electrical cabinets and is mainly used for centralized installation, fixing, and protection of various electrical components and lines. The power distribution lines are related to the needs of the unmanned hybrid vehicle. The distribution lines range from 1 to 20, with 5 to 10 lines being commonly used.

[0052] In addition, the second electrical cabinet 10 is mainly used to provide control and feedback for the signals of the unmanned hybrid train. It belongs to the category of low voltage. It is mainly used to intelligently process the signals fed back by various components of the unmanned hybrid train, and then feed back the processing results to each component. The control circuit is related to the needs of the unmanned hybrid train, and the number of lines is 1-40, with 5-20 lines being commonly used.

[0053] Example 2: like Figure 8 and Figure 9 As shown, a control method for an electrical room system for an unmanned hybrid train electrical equipment is applied to any of the electrical room systems for an unmanned hybrid train electrical equipment described in Embodiment 1. The method includes an automatic emergency cooling control method A executed by an emergency cooling control terminal 24 in an indoor / outdoor environment sensing emergency cooling system. The automatic emergency cooling control method A includes the following steps: SA1: Continuously receives indoor temperature and humidity signals from indoor temperature and humidity sensing probe 29 and outdoor temperature and humidity signals from outdoor temperature and humidity sensing probe 7, and continuously transmits the indoor temperature and humidity signals, outdoor temperature and outdoor humidity signals to the remote control center. SA2: If the indoor temperature signal or the outdoor temperature signal exceeds the set temperature value and the time exceeding the set temperature value exceeds the set duration, an over-temperature alarm signal will be sent to the remote control center; at the same time, the water spray system will be activated to spray water mist on the outside of the electrical room, and the air conditioning unit 12 will be activated to adjust the temperature and humidity inside the electrical room. SA3: When the received outdoor temperature signal is lower than the set temperature value, the water spray system stops spraying water mist on the outside of the electrical room; when the received indoor temperature signal is lower than the set temperature range and the received indoor humidity signal is lower than the set humidity range, the air conditioning unit 12 stops adjusting the temperature and humidity inside the electrical room.

[0054] Specifically, after receiving the automatic control request signal from the remote control center, the indoor and outdoor environment sensing emergency cooling system begins a self-test procedure to confirm that the conditions for automatic control are met. Then, it sends a signal to the remote control center that automatic control can be performed. After the remote control center agrees, automatic control begins.

[0055] Specifically, during the automatic control process, if the remote control receiver 23 receives an input command sent by the handheld remote control terminal, the indoor and outdoor environment sensing emergency cooling system will exit the automatic control mode and switch to the remote control mode.

[0056] Specifically, in automatic control mode, the indoor and outdoor environment sensing emergency cooling system receives the dispatch command from the remote control center through the remote signal transmitter and receiver 22. At the same time, the indoor and outdoor environment sensing emergency cooling system also provides real-time feedback on the system status to the remote control center.

[0057] Specifically, during the automatic control process, the indoor and outdoor environmental sensing emergency cooling system continuously receives signals from the indoor temperature and humidity sensing probe 29 and the outdoor temperature and humidity sensing probe 7. Simultaneously, the emergency cooling control terminal 24 transmits these signals to the remote control center. When the temperature read by the emergency cooling control terminal 24 exceeds the set temperature value and the time exceeding the set temperature value exceeds the set duration (determined by an algorithm), the emergency cooling control terminal 24 immediately transmits an over-temperature alarm signal to the remote control center. To prevent false alarm activation, a delay program is set during this process (the delay time is generally 5-20 seconds). After the delay program is completed, the emergency cooling control terminal 24 begins to operate.

[0058] Specifically, when an outdoor over-temperature alarm is triggered, the emergency cooling control terminal 24 activates the water spray system to spray water mist onto the high-temperature surfaces of the electrical room. When the received outdoor temperature signal is lower than the set temperature value, the water spray system stops spraying water mist onto the electrical room. During this process, if an action command is received from the remote control center, it will be executed accordingly. In low-temperature winter environments, antifreeze should be used instead of water to ensure that the medium in the water spray system remains in a liquid state.

[0059] In addition, when the electrical room is under over-temperature alarm, the air conditioning unit 12 will cool it down. The air conditioning unit 12 is mainly used to provide the temperature and humidity required for the operation of the electrical equipment in the electrical room. The temperature control range is 5-25℃ and the humidity control range is 5%-50%.

[0060] In this embodiment, an automatic fire extinguishing control method B, executed by the automatic fire control terminal 15 in the automatic fire extinguishing control system, is also included. The automatic fire extinguishing control method B includes the following steps: SB1: Continuously receives signals from the automatic fire alarm 20; when a fire alarm signal is received from the automatic fire alarm 20, it transmits the fire alarm signal to the remote control center for alarm activation. SB2: Activate fire extinguisher 28 to extinguish the fire inside the main body of the electrical room, and continuously receive oxygen concentration signals from oxygen concentration detector 16; SB3: When the received oxygen concentration signal is lower than the set oxygen concentration range, the fire extinguisher 28 is ordered to stop extinguishing the fire inside the main body of the electrical room.

[0061] Specifically, during the automatic fire extinguishing control process, if the remote control receiver 23 receives an input command sent by the handheld remote control terminal, the automatic fire extinguishing control system exits the automatic control mode and switches to the remote control mode.

[0062] Specifically, in automatic control mode, the automatic fire extinguishing control system receives the dispatch command from the remote control center through the remote signal transmitter and receiver 22, and at the same time, the automatic fire extinguishing control system also provides real-time feedback on the system status to the remote control center.

[0063] In addition, a power battery fire extinguishing system needs to be installed in the main body of the electrical room; temperature sensors 27 are installed on each surface of the power battery pack 8, and the signals of the temperature sensors 27 are connected to the automatic fire extinguishing control system. When the temperature monitored by the temperature sensor 27 exceeds the set value (generally 100-200℃), it will be processed according to the above process, and at this time, a special lithium battery dry powder fire extinguisher 26 will be used to extinguish the fire.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
