DETAILED DESCRIPTION

[0022] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar modules or modules with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0023] Example 1

[0024] In this embodiment, a tank truck vibration controller is specifically provided, which is used to control the on-off of the cryogenic liquid delivery pipeline on the cryogenic tank truck, mainly by collecting the vibration state to perform pipeline on-off and alarm control. Specifically, the controller is mainly composed of a control module 1 and an alarm module 11.

[0025] For Control Module 1 part:

[0026] The control module 1 includes a first MCU processing unit, a vibration sensor, a solenoid valve 7, a first wireless communication unit 4 and a solenoid valve 7 driving unit, wherein the vibration sensor, the first wireless communication unit 4 and the solenoid valve 7 driving unit are respectively connected to the first MCU for communication, and the solenoid valve 7 driving unit is electrically connected to the solenoid valve 7, which is connected in series to the cryogenic liquid delivery pipeline through its air inlet pipe interface 5 and air outlet pipe interface 6. To ensure the normal operation of each component unit in the control module 1, the control module 1 also includes: a first power supply processing unit, which is respectively electrically connected to the first MCU processing unit, the first wireless communication unit 4, the solenoid valve 7 driving unit and the vibration sensor, so as to supply power to the normal operation of the first MCU processing unit, the first wireless communication unit 4, the solenoid valve 7 driving unit and the vibration sensor through the first power supply processing unit.

[0027] In actual application, in order to display the working status of the solenoid valve 7 in real time and to be able to manually control the solenoid valve 7, the first MCU processing unit of the control module 1 is connected to the switch valve indicator light 2 and the switch valve button 3. By pressing the switch valve button 3 again, the solenoid valve 7 drive unit immediately stops driving the solenoid valve 7. At this time, the solenoid valve 7 cuts off the user's low-temperature liquid delivery pipeline.

[0028] For alarm module part 11:

[0029] The alarm module 11 includes a second MCU processing unit, a second wireless communication unit 8 and a buzzer 12 driving unit, the second wireless communication unit 8 and the buzzer 12 driving unit are respectively connected to the second MCU processing unit, and the buzzer 12 driving unit is connected to the buzzer 12. In actual application, the wireless communication connection established between the first MCU processing unit and the second MCU processing unit is realized by the short-range wireless communication between the first wireless communication unit 4 and the second wireless communication unit 8. In order to ensure the normal operation of each component unit in the alarm module 11, the alarm module 11 also includes: a second power supply processing unit, the second power supply processing unit is respectively electrically connected to the second MCU processing unit, the second wireless communication unit 8, the buzzer 12 driving unit and the redundant vibration sensor, so as to supply power to the normal operation of the second MCU processing unit, the second wireless communication unit 8, the buzzer 12 driving unit and the redundant vibration sensor through the second power supply processing unit.

[0030] In order to display the alarm status of the alarm module 11 in real time, the alarm module 11 is also provided with an alarm indicator light 10, and the alarm indicator light 10 is communicatively connected with the second MCU processing unit.

[0031] On the other hand, in order to enable the driver to manually turn off the alarm, the second MCU processing unit is also connected to a mute button 9. By pressing the mute button 9, the sound of the buzzer 12 disappears.

[0032] Among them, the alarm module 11 is installed in the tank truck cab, and the control module 1 is installed at the rear of the tank truck. When the tank truck stops and fills the storage tank and other equipment with liquid, the solenoid valve 7 needs to be opened manually. After the filling is completed, the solenoid valve 7 needs to be closed manually, and the filling pipe is removed and placed. When the tank truck stops filling, data is sent to the alarm module 11 to cancel the alarm. When the tank truck vibrates after ignition or while driving, the control module 1 detects the vibration and closes the solenoid valve 7, and sends data to the alarm module 11 to alarm.

[0033] Based on the tank truck vibration controller provided above, its working principle is as follows:

[0034] (1) When the cryogenic tank truck is ignited and started, the first MCU processing unit receives a vibration signal fed back by the vibration sensor, indicating that the tank truck is currently vibrating. The first MCU processing unit controls the solenoid valve 7 driving unit to stop driving the solenoid valve 7, so that the solenoid valve 7 cuts off the cryogenic liquid delivery pipeline. At the same time, the vibration signal is sent to the second wireless communication unit 8 through the first wireless communication unit 4. After receiving the signal, the second MCU processing unit controls the buzzer 12 to sound a buzzer alarm through the buzzer 12 driving unit. At the same time, it also controls the alarm indicator light 10 to work and flash a red light to alarm.

[0035] At this time, when the driver or staff hears the buzzer, it reminds the driver that the tank truck is about to drive and will get off the car for inspection, avoiding the leakage of cryogenic liquid caused by the failure to close the pneumatic valve after filling due to negligence of the personnel. At the same time, it can also check whether each link of filling has been processed; if there is no safety hazard, the driver or staff presses the mute button 9, the buzzer 12 disappears, the red light flashing alarm of the alarm indicator 10 remains unchanged, and the control module 1 no longer repeatedly sends out an alarm signal during the driving process of the tank truck, until the control module 1 receives the stop signal, the state of the control module 1 is reset, and the next vibration signal can trigger the control module 1 to send out an alarm signal again. The control logic is implemented in the first MCU processing unit through a control program, for example: it can be determined by the duration of the vibration signal collected by the vibration sensor. If the vibration time lasts for more than 3s, it is determined that the tank truck is driving, and the control module 1 no longer repeatedly sends out an alarm signal; if the non-vibration time lasts for more than 3s, it is determined that the tank truck stops, the state of the control module 1 is reset, and after receiving the vibration signal next time, an alarm signal will be sent to the alarm module 11.

[0036] (2) When the low-temperature tank truck stops at the destination, the first MCU processing unit does not receive the vibration signal fed back by the vibration sensor. At this time, the first MCU processing unit sends a stop signal to the second wireless communication unit 8 through the first wireless communication unit 4. The second wireless communication unit 8 feeds back information to the second MCU processing unit, and the second MCU processing unit controls the alarm indicator light 10 to turn off and the buzzer 12 to stop beeping.

[0037] At this time, press the switch valve button 3, the solenoid valve 7 driving unit immediately drives the solenoid valve 7 to connect the low-temperature liquid delivery pipeline of the tank truck. At the same time, the switch valve indicator light 2 lights up green. In the current state, the scene of parking and filling low-temperature liquid can be met; thereafter, when the tank truck completes the filling of low-temperature liquid, press the switch valve button 3 again, the solenoid valve 7 driving unit immediately stops driving the solenoid valve 7, so that the low-temperature liquid delivery pipeline of the tank truck is cut off, and the switch valve indicator light 2 lights up red.

[0038] Example 2

[0039] Based on the tank truck vibration controller provided in Example 1, the second MCU processing unit is communicatively connected to a redundant vibration sensor.

[0040] When working, the second MCU processing unit sends the vibration state collected by the redundant vibration sensor to the control module 1 through the second wireless communication unit 8, and the first MCU processing unit of the control module 1 compares the vibration state of the vibration sensor to determine the vibration state at this time. It is necessary to meet the requirements that both the vibration sensor and the redundant vibration sensor collect vibration to be determined as a vibration state; similarly, if both the vibration sensor and the redundant vibration sensor are in a stopped state, it is determined to be a stopped state.
