However, due to the particularity of the operating environment of this type of vehicle, the electronic control system may face some challenges and problems.

[0003] First, the transportation of saturated water vapor requires strict temperature control to maintain the saturated state of the steam. The current electronic control system cannot accurately control heaters and other temperature regulation equipment, resulting in overheating or underheating of the saturated water vapor.

[0004] Secondly, the transportation of saturated water vapor also involves pressure control to ensure the safety of the container and the effective transportation of steam. The current electronic control system is also unable to accurately monitor and control the pressure.

[0068] Specifically in this implementation example, the intelligent electronic control system provides a complete set of control and monitoring mechanisms for the transport trailer to ensure the safety and efficiency during transportation. The following is an introduction to the specific working process:

[0069] The steam filling pipeline 200 is connected to the steam source, and the steam is filled into the tank body 100 through the steam filling pipeline 200, and heat is exchanged through the coil 330 to heat the cooling water; the coil 330 in the heat exchange pipeline 300 exchanges heat with the cooling water in the tank body 100 to generate steam, the muffler 320 is used to reduce the noise generated by the steam flow, and the steam-water separator 310 is used to separate the steam and the unevaporated cooling water to ensure that only the steam enters the discharge pipeline 400; the liquid level monitoring pipeline 600 is used to monitor the cooling water level in the tank body 100 in real time to ensure that the amount of cooling water is within a safe range. The centralized control center 900 monitors the temperature and pressure in the tank body 100 through the controller 920 to ensure that it is within a safe range. The controller 920 adjusts the heat exchange pipeline 300 according to the monitored data. , the opening of the control valves on the steam filling pipeline 200 and the unloading pipeline 400 to control the generation and transportation of steam. During the transportation of the semi-trailer, the control center 900 continuously monitors and controls the status inside the tank 100 to ensure transportation safety. When the semi-trailer arrives at the designated unloading location, the unloading pipeline 400 is connected to the unloading end and starts to transport steam. By controlling the control valve on the unloading pipeline 400, the steam delivery volume and speed can be adjusted to complete the unloading process; the control center 900 transmits the monitored temperature, pressure, liquid level data and control valve opening data to the monitoring center or operator through the network communication module 910 for remote monitoring and operation; after unloading is completed, the steam filling pipeline 200 is closed, the steam supply is stopped, and then the system is shut down to wait for the next filling and transportation.

[0070] The entire system is designed to ensure safety and efficiency during transportation. Through real-time monitoring and control, the state inside the tank 100 can be effectively managed to prevent unsafe conditions such as overheating and overpressure. At the same time, the addition of the network communication module 910 allows the system to be remotely monitored and operated, improving operational flexibility and response speed.

[0073] Specifically in this embodiment, one end of the first pipeline is connected to the steam source to ensure that steam can enter the pipeline system. The first electric ball valve 210 is the first control point for steam to enter the system. The first electric ball valve 210 can be remotely controlled by an electric actuator to open or close the flow of steam. The opening and closing states of the first electric ball valve 210 can be adjusted by the controller 920 of the centralized control center 900 as needed to control the steam filling process; the function of the first check valve 220 is to prevent steam from flowing in the reverse direction in the system, ensuring that steam can only flow in one direction, from the steam source to the coil 330.

One end of the second pipeline close to the third temperature sensor 460 is connected to the interior of the tank body 100, and one end of the second pipeline close to the second pressure sensor 410 is suitable for connection with the unloading end.

[0075] Specifically in this embodiment, the unloading pipeline 400 is used to safely and effectively transport the steam in the tank body 100 to the unloading end. The safety and controllability of the unloading process are ensured through the precise control of a series of sensors and electric ball valves.

[0078] Specifically in this embodiment, the liquid level monitoring pipeline 600 is designed to accurately monitor the liquid level changes of the cooling water in the tank body 100 to ensure the safety and effectiveness during transportation. Accurate monitoring of the liquid level is achieved by installing an upper liquid level gauge stop valve 610, a lower liquid level gauge stop valve 620, a first liquid level gauge 630, a first liquid level gauge drain valve 640 and a second liquid level gauge 650 on one side of the tank body 100. The upper liquid level gauge stop valve 610 and the lower liquid level gauge stop valve 620 are used to control the water inlet and outlet of the liquid level gauge so that the connection between the liquid level gauge and the tank body 100 can be cut off when necessary for maintenance or cleaning. These stop valves can operate the liquid level gauge without affecting the cooling water in the tank body 100, thereby improving the safety of the system and the convenience of maintenance. The upper liquid level gauge stop valve 610 is connected in series with the first liquid level gauge 630, which means that the water flow can pass through the upper liquid level gauge stop valve 610 and then flow into the first liquid level gauge. 630; the lower level gauge stop valve 620 is connected in parallel with the upper level gauge stop valve 610 and the first level gauge 630, so that the first level gauge 630 can be bypassed when necessary and directly connected to the tank body 100; the first level gauge drain valve 640 is used to discharge impurities or air that may accumulate in the first level gauge 630 to ensure the accuracy and reliability of the level gauge. Through regular discharge, the level gauge can be prevented from malfunctioning or inaccurate readings due to impurity accumulation; the second level gauge 650 provides an additional level monitoring point, which together with the first level gauge 630 can provide more comprehensive level data. This dual monitoring can improve the redundancy of the system and ensure that when one of the level gauges fails, the other level gauge can still provide accurate level data.

[0080] Specifically in this embodiment, the temperature and pressure monitoring equipment installed at the bottom of one side of the tank body 100 is crucial to ensure transportation safety and efficiency. These devices include a first temperature sensor 110, a first thermometer 120, a first pressure sensor 130 and a first pressure gauge 140, wherein the first temperature sensor 110 is used to transmit the temperature data inside the tank body 100 in real time. This sensor is usually based on the thermoelectric effect or the principle of resistance change, and can convert temperature changes into electrical signals. The first temperature sensor 110 may include a thermocouple or a thermistor, which are connected to the controller 920 of the control center 900 to realize real-time data collection and transmission; the first thermometer 120 is used to measure the temperature inside the tank body 100 in real time. It may use a glass tube liquid thermometer or a digital display thermometer. The first thermometer 120 can provide instant temperature readings, which is convenient for operators to directly observe the temperature conditions inside the tank body on site; it is used to transmit the pressure data inside the tank body 100 in real time. The first pressure sensor 130 is usually based on piezoelectric or piezoresistive effect to convert pressure changes into electrical signals. These sensors can detect pressure changes in the tank body and convert them into digital signals, and perform real-time data collection and transmission through the controller 920 of the control center 900; the first pressure gauge 140 is used to measure the pressure inside the tank body 100 in real time. The pressure gauge can be mechanical (such as spring tube type) or electronic. The first pressure gauge 140 provides an intuitive pressure reading, so that the operator can quickly understand the pressure status inside the tank body 100 on site.

[0086] The water replenishment pipeline 700 includes an upper water replenishment branch 710 and a lower water replenishment branch 720, which are respectively connected to the upper and lower ends of the tank body 100. The upper water replenishment branch 710 is used to replenish cold water from the top when the cooling water level inside the tank body 100 is low, so as to ensure that the water volume in the tank body 100 is maintained at an appropriate level; the lower water replenishment branch 720 replenishes water from the bottom after the tank body 100 is emptied, so as to ensure that the tank body has sufficient water before or during transportation; the water replenishment process can also be automatically controlled by the controller 920 of the control center 900 according to the liquid level monitoring data, or it can be manually operated.

[0087] The drain pipe 800 is installed on one side of the top of the tank body 100 to discharge the steam and condensed water inside the tank body 100. Before transportation or after unloading, the steam and condensed water inside the tank body 100 may need to be discharged. The drain pipe 800 achieves this function through the drain valve on the top. The draining process can also be remotely controlled by the controller 920 of the centralized control center 900 to ensure that the pressure and humidity inside the tank body are controlled within a safe range.

[0088] For further information, see Figure 1 , 2 As shown, the sewage discharge pipeline 500 includes a first sewage discharge outlet ball valve 510 and a first sewage discharge outlet stop valve 520 which are connected in sequence, and the first sewage discharge outlet ball valve 510 and the first sewage discharge outlet stop valve 520 are both electrically connected to the controller 920 .

[0089] Specifically in this embodiment, the sewage pipeline 500 is to ensure the cleanliness of the inside of the tank body 100 and prevent the accumulation of impurities and possible blockage problems. The first sewage outlet ball valve 510 is usually used to control the flow of fluids and can quickly open or close the pipeline. The first sewage outlet ball valve 510 is the main control point of the sewage outlet pipeline, allowing the operator to remotely control the opening and closing of the valve. When sewage discharge operation is required, the controller 920 will send a signal to the first sewage outlet ball valve 510 to open it, thereby allowing the impurities inside the tank body 100 to be discharged through the sewage outlet pipeline 500; the first sewage outlet stop valve 520 is mainly used to accurately control the flow of fluids and is suitable for occasions where the flow rate needs to be carefully adjusted. The first sewage outlet stop valve 520 is another control point of the sewage outlet pipeline, which can provide additional control after the first sewage outlet ball valve 510. In some cases, it may be necessary to slowly discharge impurities to prevent environmental pollution or avoid sudden ejection of impurities. At this time, the first sewage outlet stop valve 520 can adjust the opening to accurately control the sewage discharge speed.

[0090] For further information, see Figure 1 , 2 As shown, the upper water replenishment branch 710 includes an upper water replenishment port ball valve 711 and an upper water replenishment port stop valve 712 which are sequentially connected from the outside to the tank body 100; the lower water replenishment branch 720 includes a lower water replenishment port ball valve 721 and a lower water replenishment port stop valve 722 which are sequentially connected from the outside to the tank body 100.

[0091] Specifically in this embodiment, the upper water replenishment inlet ball valve 711 is used to control the opening and closing of the water replenishment. When the cooling water level inside the tank body 100 is low, cold water needs to be added. At this time, the upper water replenishment inlet ball valve 711 is opened to allow water to enter the tank body 100. The upper water replenishment inlet ball valve 711 switches quickly and has good sealing performance, which is suitable for occasions that require frequent operation; the upper water replenishment inlet stop valve 712 is installed downstream of the upper water replenishment inlet ball valve 711, and is used to accurately control the water replenishment flow and cut off the water flow in an emergency. The upper water replenishment inlet stop valve 712 has high adjustment accuracy and is suitable for occasions that require fine flow adjustment.

[0092] The function of the lower water replenishment port ball valve 721 is similar to that of the upper water replenishment port ball valve 711, but it is installed on the bottom side of the tank body 100, and is used to replenish water from the bottom after the tank body 100 is emptied. When the tank body 100 needs to be completely emptied and refilled with water, the lower water replenishment port ball valve 721 opens to allow water to enter the tank body; the lower water replenishment port stop valve 722 has a similar function to the upper water replenishment port stop valve 712, but it is located on the lower water replenishment branch 720, and is used to control and cut off the water flow of the lower water replenishment port ball valve 721. When it is necessary to accurately control the water replenishment amount or to cut off the water source in an emergency, the lower water replenishment port stop valve 722 comes into play.

[0093] For further information, see Figure 1 , 2As shown, the emptying pipeline 800 includes a first exhaust branch and a second exhaust branch connected in parallel on one side of the tank body 100, the first exhaust branch and the second exhaust branch are connected in series with one end of the emptying port stop valve 850 at a side away from the tank body 100, and the other end of the emptying port stop valve 850 is connected between the upper water supply port ball valve 711 and the upper water supply port stop valve 712;

[0094] The first exhaust branch includes a first safety valve 810 and a second gas outlet ball valve 820 connected in series, and an end of the second gas outlet ball valve 820 away from the first safety valve 810 is connected to the tank body 100;

[0095] The second exhaust branch includes a second safety valve 830 and a first safety valve stop valve 840 connected in series, and one end of the first safety valve stop valve 840 away from the second safety valve 830 is connected to the tank body 100 .

[0096] Specifically in this embodiment, the emptying pipeline 800 is provided to discharge the steam and condensed water in the tank body 100 when necessary. The emptying pipeline 800 includes a first exhaust branch and a second exhaust branch, which are connected in parallel on one side of the tank body 100 and are connected in series with one end of the emptying port stop valve 850 on the side away from the tank body 100. The other end of the emptying port stop valve 850 is connected between the upper water replenishment port ball valve 711 and the upper water replenishment port stop valve 712. The function of the first safety valve 810 is to automatically open when the internal pressure of the tank body 100 exceeds the set value, release excessive pressure, so as to protect the tank body and transportation safety. The second outlet ball valve 820 is used to control the steam flow discharged from the tank body 100, which can be remotely or manually controlled to adjust the discharge speed.

[0097] The drain stop valve 850 is located downstream of the first exhaust branch and the second exhaust branch. It controls the discharge of steam and condensed water to the external environment. The drain stop valve 850 can accurately control the discharge process, ensure the smooth reduction of the internal pressure of the tank body 100, and avoid the risks caused by a sudden drop in pressure.

[0098] See also Figure 3 As shown, another embodiment of the present invention further provides an intelligent electric control method for a transport trailer, which is applied to the above-mentioned intelligent electric control system for a transport trailer, and the electric control method includes a filling process and a unloading process;

[0099] The filling process comprises the following steps:

[0100] Step S1: When filling, all valves are closed, a certain amount of cooling water is filled into the tank body 100, and superheated steam is filled into the tank body 100 through the steam filling pipeline 200;

[0101] Step S2: The superheated steam exchanges heat with the cooling water in the tank 100 through the heat exchange pipeline 200, so that the cooling water is fully heated to reach saturated water at a corresponding pressure;

[0102] Step S3: The first temperature sensor 110, the first pressure sensor 130, the steam filling pipeline 200, the heat exchange pipeline 300, the liquid level monitoring pipeline 600, the water supply pipeline 700 and the emptying pipeline 800 collect temperature data, pressure data and liquid level data in the tank body 100 in real time, and transmit the data to the controller 920 for analysis and calculation through the network communication module 910;

[0103] Step S4: the controller 920 controls the steam filling pipeline, the heat exchange pipeline, the water supply pipeline and the emptying pipeline to maintain the temperature and pressure in the tank within a set range;

[0104] Step S5: remotely observe the temperature, pressure and liquid level data in the tank 100 in real time through the centralized control center 900, and control the closure of the steam filling pipeline 200, the heat exchange pipeline 300, the water supply pipeline 700 and the emptying pipeline 800;

[0105] The unloading process comprises the following steps:

[0106] Step S6: After the tank body 100 is filled, the transport semi-trailer transports the tank body 100 to the designated unloading location, and the unloading pipeline 400 is connected to the unloading end to transport steam to the outside;

[0107] Step S7: controlling the outlet pressure and outlet flow rate of the discharge pipeline 400 through the controller 920, wherein the outlet pressure ranges from 0.4 to 2.5 MPa, and the outlet flow rate ranges from 250 to 4000 kg / h;

[0108] Step S8: After the material is discharged to the specified pressure, the controller 920 controls all valves to close.

[0109] Therefore, through intelligent electronic control methods, the pressure, temperature and liquid level inside the tank can be monitored in real time to ensure that filling and unloading are carried out within a safe range and prevent accidents caused by overpressure, overheating or abnormal liquid level; intelligent control methods can automate the filling and unloading processes, reduce manual operations, improve work efficiency, and shorten loading and unloading time; precise control of electric ball valves, safety valves and stop valves can ensure accurate filling and unloading of liquids, avoid waste of resources and environmental pollution; through the remote monitoring module, operators can monitor and operate the semi-trailer in a safe location, improving the flexibility and convenience of operation.
