[0026] When a pump truck unloads liquid to a small storage tank, it is necessary to pair the identity information of the small storage tank, monitor and control the unloading process, and record the unloading information at the same time. However, due to the different distribution scenarios of small storage tanks, when the pump truck unloads liquid to a small storage tank, the background management personnel cannot timely understand and master the unloading progress, thus affecting the supervision and control of the unloading. Therefore, a storage tank control system is proposed to solve the above problems.

[0027] Its solution is further described through the following embodiments:

[0028] Figure 1 It is a schematic diagram of the storage tank control system in the embodiment of the present utility model.

[0029] The storage tank control system of this embodiment can be applied to a storage tank for monitoring and controlling the filling of the medium in the storage tank, so as to achieve the purpose of monitoring the filling medium of the storage tank. Among them, the medium in the storage tank can be propane, LNG, liquefied petroleum, etc.

[0030] Please refer to Figure 1 , the storage tank control system may include a liquid phase pipeline, a gas phase pipeline, a monitoring component, a controller 1, and a wireless communication component.

[0031] Among them, both the liquid phase pipeline and the gas phase pipeline can be connected to the storage tank.

[0032] Specifically, the liquid phase pipeline is connected to the storage tank so that an external filling device can fill the medium into the storage tank through the liquid phase pipeline. And a liquid phase valve 4 can be provided on the liquid phase pipeline, and the liquid phase valve 4 can be used to control the connection or disconnection of the liquid phase pipeline. It should be noted that the liquid phase pipeline can also be used to discharge the medium in the storage tank outward.

[0033] At the same time, the gas phase pipeline can be used to balance the air pressure in the storage tank, and a gas phase valve 5 can be provided on the gas phase pipeline. The gas phase valve 5 can be used to control the connection or disconnection of the gas phase pipeline, so as to ensure the air pressure balance in the storage tank and facilitate the filling or discharging of the medium.

[0034] In this embodiment, the controller 1 can be arranged in the control cabinet of the storage tank. Specifically, the controller 1 can be integrated on the main control module, and the main control module is installed in the control cabinet to form protection for the main control module.

[0035] In addition, the controller 1 can be electrically connected to the liquid phase valve 4 and the gas phase valve 5, so that the controller 1 can control the conduction or cutoff of the liquid phase valve 4 and the gas phase valve 5, and further control the connection or disconnection of the liquid phase pipeline and the gas phase pipeline.

[0036] At the same time, the monitoring component can be connected to the storage tank to monitor the state of the storage tank, such as the pressure in the storage tank and the liquid level height in the tank, etc., and form monitoring information.

[0037] In this embodiment, the controller 1 can also be electrically connected to the monitoring component, so that the controller 1 can read the monitoring information detected by the monitoring component, and the controller 1 can control the conduction or cutoff of the liquid phase valve 4 and the gas phase valve 5 according to the monitoring information.

[0038] Specifically, the monitoring component can include a liquid level gauge 21 and a pressure monitoring component. Among them, the liquid level gauge 21 is connected to the storage tank to collect the liquid level information in the storage tank. The pressure monitoring component is connected to the storage tank to collect the pressure information in the storage tank. That is, in this embodiment, the monitoring information can include liquid level information and pressure information.

[0039] It should be noted that in this embodiment, the pressure monitoring component may include a first pressure transmitter 22 and a second pressure transmitter 23. Among them, the operating pressure value of the first pressure transmitter 22 is greater than that of the second pressure transmitter 23, so that when the pressure in the storage tank drops outside the operating pressure range of the first pressure transmitter 22, the second pressure transmitter 23 can continue to monitor the pressure in the storage tank, thereby obtaining more accurate pressure information and ensuring the safe use of the storage tank.

[0040] In this embodiment, the wireless communication component may be connected to the controller 1 and can be wirelessly connected to the operation platform 2 and the external filling device 3, so that the controller 1 can wirelessly communicate with the operation platform 2 and the external filling device 3 through the wireless communication component.

[0041] It should be noted that the operation platform 2 may be an operation management platform located in the background, enabling staff to monitor and control the filling of the storage tank on the operation platform 2. The external filling device 3 may be set as a pump truck, and a central control system may be provided on the pump truck so that the external filling device 3 can communicate with the controller 1 on the storage tank through the wireless communication component. The external filling device 3 can be connected to the liquid phase pipeline and fill the storage tank with the medium through the liquid phase pipeline.

[0042] Specifically, the controller 1 can send or receive signals to the operation platform 2 through the wireless communication component, so that the operation platform 2 can remotely read the monitoring information, or the operation platform 2 can control the opening or closing of the liquid phase valve 4 and the gas phase valve 5 through the controller 1. That is, the operation platform 2 can obtain the monitoring information of the storage tank through the controller 1 and wirelessly communicate with the controller 1 to send instructions or signals to the controller 1, so that the controller 1 controls the opening or closing of the liquid phase valve 4 and the gas phase valve 5, thereby achieving the purpose of remote monitoring and control.

[0043] At the same time, the external filling device 3 can identify and connect to the controller 1 through the wireless communication component, so that the controller 1 can transmit the monitoring information to the external filling device 3. That is, the external filling device 3 is connected and paired to the controller 1 on the storage tank through the wireless communication component and judges whether the storage tank can be filled with the medium according to the monitoring information.

[0044] Specifically, the wireless communication component may include a LoRa module 11.

[0045] Among them, the LoRa module 11 is electrically connected to the controller 1, and the LoRa module 11 can be used for wireless transmission, so that in the local area network, the external filling device 3 can be wirelessly connected to the controller 1 through the LoRa module 11, enabling the controller 1 to transmit the monitoring information to the external filling device 3.

[0046] In this embodiment, the identity recognition information of the storage tank is set in the LoRa module 11. The external filling device 3 can identify and pair with the storage tank through the identity recognition information, so that the external filling device 3 can fill the medium into the storage tank. That is, the identity recognition information of the storage tank is set in the LoRa module 11, and the external filling device 3 can communicate with the controller 1 through the LoRa module 11 and identify and match the storage tank through the identity recognition information, so that the external filling device 3 can accurately communicate with the storage tank that needs to be connected and fill the medium into the storage tank.

[0047] In addition, the wireless communication component may further include a communication module 12 and a GPS module 13.

[0048] Among them, the communication module 12 can be used for communication connection, so that wireless communication can be carried out between the operation platform 2 and the controller 1 through the communication network. Specifically, the communication module 12 can be set as a 3G module, a 4G module, a 5G module or a WI FI module, etc., so that communication connection can be carried out between the controller 1 and the operation platform 2 through the communication module 12.

[0049] The GPS module 13 can be used to receive position signals to real-time feedback the position information of the storage tank, so as to facilitate the staff of the operation platform 2 to master the position information of the storage tank in real time, and then command the external filling device 3 to find and connect to the storage tank. Of course, in some other embodiments, the GPS module 13 can be set as a Beidou positioning module to be used for feedback the position information of the storage tank.

[0050] Refer to Figure 1 , the storage tank control system may further include a combustible gas detector 6 and an audible and visual alarm 7.

[0051] Among them, the combustible gas detector 6 is connected to the tank body to monitor the tank body and form an alarm signal when the medium leaks from the tank body.

[0052] In this embodiment, the combustible gas detector 6 can be electrically connected to the controller 1 to be able to transmit the alarm signal to the controller 1. That is, when the combustible gas detector 6 detects that the storage tank has a gas leak, the combustible gas detector 6 can form an alarm signal and transmit it to the controller 1, so that the controller 1 can control the liquid phase valve 4 and the gas phase valve 5 to close to ensure the safety of the storage tank.

[0053] At the same time, the audible and visual alarm 7 can be electrically connected to the controller 1, so that the controller 1 can control the audible and visual alarm 7 to turn on or off.

[0054] Specifically, after receiving the alarm signal formed by the combustible gas detector 6, the controller 1 can control the audible and visual alarm 7 to work, so that the audible and visual alarm 7 can emit alarm sounds and alarm lights, and enable the staff around the storage tank to quickly locate the storage tank that issues the alarm. Furthermore, the staff can promptly stop filling the storage tank with the medium and timely handle the emergencies occurring in the storage tank, ensuring the safe use of the storage tank.

[0055] Certainly, when the monitoring information received by the controller 1 exceeds the preset value, the controller 1 can also control the audible and visual alarm 7 to work to alarm the on-site operators, reminding the operators to suspend operations or take emergency measures, thereby ensuring that the storage tank is within a safe range.

[0056] In this embodiment, the storage tank control system may further include an emergency stop button 8 and a reset button 9.

[0057] Among them, both the emergency stop button 8 and the reset button 9 can be installed on the control cabinet. And, the emergency stop button 8 can be electrically connected to the controller 1 to be able to transmit an emergency stop signal to the controller 1. That is, when the on-site staff presses the emergency stop button 8, the emergency stop button 8 can transmit an emergency stop signal to the controller 1, enabling the controller 1 to control the closing of the liquid phase valve 4 and the gas phase valve 5 according to the emergency stop signal and locking the liquid phase valve 4 and the gas phase valve 5 to prevent the liquid phase valve 4 and the gas phase valve 5 from conducting. At the same time, the controller 1 can control the external filling device 3 to stop filling the storage tank with the medium, thereby avoiding the leakage of the medium in the storage tank and ensuring the safety of the storage tank.

[0058] At the same time, the reset button 9 can be electrically connected to the controller 1 to be able to transmit a reset signal to the controller 1, enabling the controller 1 to release the lock on the liquid phase valve 4 and the gas phase valve 5, so that the liquid phase valve 4 and the gas phase valve 5 can be conducted or shut off, and enabling the external filling device 3 to continue filling the storage tank with the medium.

[0059] In summary, the storage tank control system can identify and match with the external filling device 3 through the LoRa module 11, enabling the external filling device 3 to be connected to a specific storage tank. At the same time, the controller 1 transmits the liquid level information read by the liquid level gauge 21 and the pressure information read by the first pressure transmitter 22 or the second pressure transmitter 23 to the external filling device 3, enabling the external filling device 3 to determine whether to fill the storage tank with the medium according to the liquid level information and the pressure information.

[0060] When the external filling device 3 fills the storage tank with the medium, the controller 1 can control the liquid phase valve 4 and the gas phase valve 5 to open, enabling the storage tank to be connected to the external filling device 3, and thus enabling the external filling device 3 to fill the storage tank with the medium.

[0061] Meanwhile, the controller 1 is connected to the operation platform 2 through the communication module 12 to transmit the status information of the storage tank to the operation platform 2, enabling the staff in the background to remotely monitor the status of the storage tank in real time and send signals to the controller 1 through the communication module 12, so that the staff of the operation platform 2 can control the opening or closing of the liquid phase valve 4 and the gas phase valve 5 through the controller 1, enabling the liquid phase pipeline and the gas phase pipeline to be connected or disconnected, and further controlling the filling process of the external filling device 3 for the storage tank. In addition, the staff of the operation platform 2 can also control the operation of the sound and light alarm 7, the emergency stop button 8 and the reset button 9 through the controller 1 to ensure the safety of the storage tank.

[0062] Figure 2 is the flowchart of the filling control method for the storage tank according to the embodiment of the present invention.

[0063] Refer to Figure 2 , the filling control method for the storage tank in this embodiment is applicable to the aforementioned storage tank control system. Specifically, the filling control method for the storage tank includes the following steps:

[0064] S1: The controller 1 obtains monitoring information through the monitoring component and transmits the monitoring information to the external filling device 3 and the operation platform 2 through the wireless communication component. Among them, the monitoring information may include liquid level information and pressure information.

[0065] S2: Determine whether the storage tank needs to be filled according to the monitoring information. When the liquid level information and pressure information in the storage tank are lower than the preset values, the operation platform 2 can determine that the storage tank needs to be filled.

[0066] S3: When it is determined that the storage tank needs to be filled, the external filling device 3 identifies and connects to the controller 1 through the wireless communication component and makes the external filling device 3 match the storage tank. Specifically, when the storage tank needs to be filled with a medium, the operation platform 2 notifies and commands the external filling device 3 to move around the storage tank, so that the external filling device 3 can identify and connect to the controller 1 through the LoRa module 11 of the wireless communication component and match the storage tank to be filled.

[0067] S4: The external filling device 3 fills the storage tank. Specifically, after the external filling device 3 is matched with the storage tank, the external filling device 3 connects to the storage tank through the liquid phase pipeline.

[0068] In this embodiment, the filling control method for the storage tank may further include the following steps:

[0069] S5: The controller 1 controls the liquid phase valve 4 and the gas phase valve 5 to open, enabling the external filling device 3 to fill the medium into the storage tank.

[0070] S6: Real-time monitor the status of the storage tank through the monitoring component, enabling the controller 1 to obtain the monitoring information.

[0071] S7: Determine whether the storage tank needs to stop filling according to the monitoring information.

[0072] S8: When it is determined that the storage tank needs to stop filling, the controller 1 controls the liquid-phase valve 4 and the gas-phase valve 5 to shut off, so that the external filling device 3 stops filling the storage tank with the medium.

[0073] It should be noted that during the filling process of the storage tank by the external filling device 3, the combustible gas detector 6 monitors the storage tank in real time. When the combustible gas detector 6 detects that there is a leakage of the medium, the combustible gas detector 6 will transmit an alarm signal to the controller 1, enabling the controller 1 to control the shut-off of the liquid-phase valve 4 and the gas-phase valve 5 according to the alarm signal, and transmit information to the external filling device 3 through the LoRa module 11, so that the external filling device 3 stops filling, thus ensuring the safety during the filling process of the storage tank.

[0074] Therefore, the filling control method of the storage tank can determine whether the storage tank is filled with the medium. When the storage tank needs to be filled, the operation platform 2 and the controller 1 can remotely control the external filling device 3 to automatically identify and match the storage tank, so that the external filling device 3 can fill the storage tank with the medium, and automatically stop filling after the filling is completed.

[0075] Although the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be broadly construed within the spirit and scope defined by the appended claims. Therefore, all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
