[0039] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0040] Figure 1 A system structure of the mobile heat supply vehicle control system provided by the embodiment of the present application, as Figure 1 shown, the system structure may include: a programmable logic controller CPU module 10, a control module 20, a communication module 30, a host computer 40, a data acquisition module 50, and an actuator 60.

[0041] Among them, the programmable logic controller CPU module 10 is connected to the communication module 30, the data acquisition module 50, and the control module 20. The communication module 30 is connected to the host computer 40, and the control module 30 is connected to the data acquisition module 50 through the actuator 60.

[0042] Specifically, the programmable controller CPU module 10 can be used to process the data of other acquisition, control, communication and other modules to implement control logic.

[0043] The control module 20 can be divided into an analog quantity control module and a digital quantity control module. According to the information obtained by the data acquisition module 50, by writing control logic and algorithms in the programmable logic controller CPU module 10, the optimal heat storage and heat supply strategies are calculated, and the actuator 60 is controlled to perform corresponding operations.

[0044] The communication module 30 can implement functions such as data upload and instruction issuance between the host computer 40 and the programmable logic controller CPU module 10.

[0045] The data acquisition module 50 may include a temperature data acquisition module 51, a pressure data acquisition module 52, and a liquid level data acquisition module 53.

[0046] Among them, the temperature data acquisition module 51 may include a temperature sensor installed on the heat storage tank of the heating system of the mobile heating vehicle, which can be used to collect the temperature data inside the heat storage tank. The pressure data acquisition module 52 may include a pressure sensor installed on the heat storage tank, which can be used to collect the air pressure data inside the heat storage tank. The liquid level data acquisition module 53 can be used to collect the water level data inside the heat storage tank.

[0047] Furthermore, as Figure 2 shown, the host computer 40 may include a human-machine interface 41 and a remote system 42, and both the human-machine interface 41 and the remote system 42 are connected to the communication module 30.

[0048] Specifically, the human-machine interface 41 can adopt an industrial touch screen, which is used to display the operating status, parameter information, and fault alarms of the control system, and provide a human-machine interaction interface to facilitate users to operate and set.

[0049] Furthermore, as Figure 3 shown, the remote system 42 may include a remote module 421 and a remote platform 422. The remote platform 422 is connected to the communication module 30 through the remote module 421.

[0050] Specifically, the remote module 421 can be used to monitor the mobile heating vehicle on the remote platform 422. The remote platform 422 can achieve the same functions of the human-machine interaction interface through data exchange with the remote module 422, and improve functions such as data analysis.

[0051] It can be understood that the programmable logic controller CPU module 10 receives the instructions sent from the human-machine interface 41 or the remote platform 422 to the remote module 421 through the communication module 30, and realizes the corresponding logic control and data feedback. The programmable controller CPU module 10 receives the data of the heat storage tank of the heating system of the mobile heating vehicle and the status of the actuator 60 through the data acquisition module 50, and then combines the instructions given by the host computer 40, and through the programmable controller CPU module 40, issues corresponding control instructions to the control module 20, and the control instructions are used by the control module 20 to control the actuator 60 to act.

[0052] The mobile heat supply vehicle control system provided by this embodiment includes an actuator acting on the mobile heat supply vehicle and a data acquisition module for collecting data of the mobile heat supply vehicle. Structurally, the programmable logic controller CPU module is connected to a communication module, a data acquisition module, and a control module. The communication module is connected to a host computer, and the control module is connected to the data acquisition module through the actuator. Thus, compared with the traditional heat supply control system, the structure of the mobile heat supply vehicle control system is simpler, the equipment is more concise, and the system can adjust according to the data in the heat storage tank of the heat supply system, effectively improving the heat supply efficiency, thereby enhancing the safety and stability of the equipment.

[0053] In some embodiments of the present application, the mobile heat supply vehicle mentioned in the above embodiment is further introduced. The mobile heat supply vehicle may include a transport vehicle and a heat supply system. Among them, the heat supply system may include a water tank type heat supply pipeline and a heat storage tank. The water tank type heat supply pipeline may include a steam supply / discharge pipe, a steam inlet / water inlet pipe, and a phase change material pipe layer.

[0054] Specifically, the phase change material pipe layer may include a phase change material. As Figure 4 shown, the steam supply / discharge pipe, the phase change material pipe layer, and the steam inlet / water inlet pipe are combined into a three-layer concentric circle structure. The steam supply / discharge pipe wraps the phase change material pipe layer, and the phase change material pipe layer wraps the steam inlet / water inlet pipe.

[0055] It can be understood that the steam inlet / water inlet pipe is used to fill the high-temperature and high-pressure steam into the tank body. During this process, the phase change material pipe layer wrapping the steam inlet / water inlet pipe can fully absorb heat from the pipe wall of the steam inlet / water inlet pipe, quickly absorb heat from the solid state to the liquid state within a short time, and make the phase change material of the phase change material pipe layer quickly reach the state of meeting the heat preservation of the steam supply / discharge pipe. When it is necessary to output steam through the steam supply / discharge pipe, the phase change material pipe layer wrapped by the steam supply / discharge pipe keeps the steam in the steam supply / discharge pipe warm and heated by heat conduction, maintaining the quality of the output steam.

[0056] Furthermore, as Figure 5 and Figure 6 shown, considering that the high-temperature and high-pressure steam needs to fully heat the demineralized water in the tank body, the steam inlet / water inlet pipe should be connected to the relevant structure in the tank body (such as the steam inlet branch pipe), and the steam supply / discharge pipe is used to transport steam. The port of the steam supply / discharge pipe should be in the upper position in the vertical direction in the tank body. The main function of the phase change material pipe layer is to keep the transported steam warm and heated. Therefore, the steam supply / discharge pipe should completely fit and wrap the phase change material pipe layer. Based on this, the relative relationship between the lengths of each pipe is:

[0057] The length of the steam supply / discharge pipe is the same as the length of the phase change material pipe layer, and the length of the steam inlet / water inlet pipe is greater than the length of the steam supply / discharge pipe.

[0058] Considering that the state of the phase change material switches between a solid state and a liquid state, the phase change material tube layer needs to be sealed, and specifically, the two ends of the phase change material tube layer can be sealed.

[0059] Furthermore, the first end of the water tank type heating pipeline is located in the heat storage tank, and the second end of the water tank type heating pipeline is located at a preset distance in front of the pipeline interface outside the heat storage tank.

[0060] Specifically, since the steam inlet / water inlet pipe and the steam supply / steam release pipe are nested into one pipe, only one joint is needed outside the heat storage tank, and the operator can operate the corresponding functions of the steam inlet / water inlet pipe, or the corresponding functions of the steam supply / steam release pipe, thereby improving the convenience of operation.

[0061] It is understandable that the steam inlet / water inlet pipe and the steam supply / steam exhaust pipe are nested into one pipe, which can directly enter the water storage tank through one opening. The steam inlet / water inlet pipe and the steam supply / steam exhaust pipe are concentric sleeves, which can save the layout space of the water tank type heating system and reduce the number of valves arranged in the water tank type heating system. Figure 6 As shown, the heat storage tank may be provided with a sensor interface, and a gate valve and a regulating valve are connected to the sensor interface.

[0062] Specifically, the sensor interface may be connected to the regulating valve via a gate valve.

[0063] Furthermore, since the length of the steam / water inlet pipe is longer than that of the phase change material pipe layer and the steam supply / release pipe, one end of the three is aligned outside the heat storage tank, and only the steam / water inlet pipe extends longer inside the heat storage tank.

[0064] Specifically, one end of the phase change material tube layer, one end of the steam supply / steam exhaust pipe, and one end of the steam inlet / water inlet pipe are all aligned at the second end. The other end of the phase change material tube layer is aligned with the other end of the steam supply / steam exhaust pipe, and both extend in the heat storage tank but not to the first end. The other end of the steam inlet / water inlet pipe extends in the heat storage tank to the first end.

[0065] Further, such as Figure 5 As shown, the heat storage tank includes a steam inlet branch pipe, and the steam inlet branch pipe is connected to a plurality of gas distribution pipes for uniformly conveying high-temperature and high-pressure steam for heating the desalted water in the heat storage tank.

[0066] Based on this, one end of the steam / water inlet pipe in the heat storage tank can be connected to the steam inlet branch pipe, and one end of the phase change material tube layer in the heat storage tank and one end of the steam supply / steam release pipe in the heat storage tank are not connected to the steam inlet branch pipe.

[0067] Furthermore, the structure of the water tank type heating pipeline in the heat storage tank is as follows Figure 6As shown, the phase change material tube layer and the steam supply / discharge pipe extend linearly without bending inside the heat storage tank. The steam inlet / water inlet pipe extends linearly inside the heat storage tank and then bends towards the steam inlet branch pipe to connect with the steam inlet branch pipe.

[0068] It can be understood that when the steam inlet / water inlet pipe is filled with steam, it can quickly heat the phase change material and preheat the steam supply / discharge pipe. When using steam, the phase change material transfers heat to the steam inside the steam supply / discharge pipe. The different extension lengths of the two pipes inside the tank do not affect their respective usage functions.

[0069] In some embodiments of the present application, the actuator 60 mentioned in the foregoing embodiments is further introduced. Specifically, the actuator 60 may include a master control electric gate valve, a single control electric gate valve, and a jacket valve.

[0070] Among them, as Figure 7 shown, the master control electric gate valve can be arranged on the water tank type heating pipeline to simultaneously control the opening and closing of the steam supply / discharge pipe and the steam inlet / water inlet pipe. The single control electric gate valve can be arranged on the steam inlet / water inlet pipe to control the opening and closing of the steam inlet / water inlet pipe. The jacket valve can be arranged on the steam supply / discharge pipe to control the opening and closing of the steam supply / discharge pipe.

[0071] Specifically, the control process of the mobile heating vehicle can be achieved in the following way:

[0072] There is only one pipeline entering the heat storage tank as a whole. Therefore, setting a master control electric gate valve can close two gas channels. The master control electric gate valve is in the normally open state. When filling water / steam, open the single control electric gate valve of the steam inlet / water inlet pipe and close the jacket valve of the steam supply / discharge pipe. The temperature sensor and pressure sensor monitor the data inside the heat storage tank. After the heat storage tank is filled with heat, close the electric gate valve of the steam inlet / water inlet pipe. When discharging steam, open the jacket valve, and the electric gate valve of the water inlet pipe is in the closed state. After the sensor detects that the air pressure and temperature inside the tank drop to the preset value, the jacket valve is automatically closed. When there is a fault in the valve of the steam inlet / water inlet pipe or the steam supply / discharge pipe, the main valve will automatically close, and the vehicle will return to the factory for maintenance.

[0073] The mobile heating vehicle control system provided in this embodiment, under the arrangement of each valve of the actuator, combines the data feedback of temperature and pressure to achieve high-efficiency heating, realizes heat storage of the system through the combination of liquid level and pressure, and realizes the maintenance of the system through the monitoring of the upper computer, providing intelligent analysis and maintenance opinions for safety.
