[0044] The tank truck transportation monitoring system provided by the utility model can further include a field monitoring device which is located on the tank truck, for example, can be installed in the cab of the tank truck. The field monitoring device can have a display screen, for example, can be a display and control integrated screen. The field monitoring device is electrically connected (for example, connected through a wire harness) with the manhole monitoring camera and the oil unloading valve monitoring camera, and includes a communication module (such as a 4G or 5G mobile communication module) capable of wireless communication with the background monitoring device; the field monitoring device is used to acquire the video recorded by the manhole monitoring camera and the oil unloading valve monitoring camera, and transmit the acquired video to the background monitoring device through the communication module. The field monitoring device can transmit the acquired video to the background monitoring device in real time through the communication module, or first store the acquired video in a local storage, and then transmit the video stored in the local storage and / or the video acquired in real time to the background monitoring device when needed. The capacity of the local storage is usually limited, so the local storage can only store video of a predetermined time length or a predetermined size, and when the video stored in the local storage reaches the predetermined time length or the predetermined size, if it is necessary to continue to store video, the earliest video data stored in the local storage can be overwritten in sequence by using the latest acquired video data, so that the data stored in the local storage is always the latest video data.

[0045] The field monitoring device can transmit the acquired video to the background monitoring device through the communication module when the manhole cover or the oil unloading valve is opened.

[0046] Whether the manhole cover or the oil unloading valve is opened can be determined by AI recognition of the video collected by the corresponding monitoring camera. AI recognition can be performed by the field monitoring device, or the field monitoring device can transmit the video to the background monitoring device for AI recognition by the background monitoring device.

[0047] Since the data amount of the video collected by the camera is large, AI recognition of all video frames will consume a large amount of computing resources, in order to save computing resources, a sampling method can be used to acquire video frames from the video frames collected by each camera every predetermined time length (such as 5 seconds), and then AI recognition is performed.

[0048] When it is detected that a manhole cover or an oil unloading valve is opened, the field monitoring device can only transmit the video data collected by the camera responsible for monitoring the manhole cover or the oil unloading valve to the background monitoring device, or can transmit the video data collected by a larger number of cameras including the camera responsible for monitoring the manhole cover or the oil unloading valve, or even all cameras, to the background monitoring device, to achieve more comprehensive monitoring.

[0049] When the manhole cover or the oil discharge valve is opened, the on-site monitoring device can transmit the real-time video data obtained to the background monitoring device through the communication module; in order to realize more reliable and comprehensive monitoring, the video data recorded before the current time for a predetermined time length and the real-time video data obtained can also be transmitted to the background monitoring device.

[0050] Of course, whether the manhole cover or the oil discharge valve is opened can also be determined by other means; for example, a position sensor for monitoring the position of each manhole cover and oil discharge valve can also be installed on the tank body 3.

[0053] The on-site monitoring device can further comprise a loudspeaker and a positioning module for positioning the tank car, and the on-site monitoring device is further used for acquiring positioning information of the tank car through the positioning module, and sending a first control signal to the loudspeaker and / or the communication module according to the positioning information.

[0054] Specifically, when it is determined according to the positioning information that the tank car deviates from the predetermined route, the on-site monitoring device can control the loudspeaker to issue a first voice prompt information, and send a first alarm information to the background monitoring device through the communication module.

[0055] The first control signal can be a signal for controlling the loudspeaker to issue the first voice prompt information, or can be a signal for controlling the communication module to send the first alarm information to the background monitoring device.

[0056] The field monitoring device can directly determine whether the tank truck deviates from the predetermined route according to the positioning information, or can first send the positioning information to the background monitoring device, and determine whether the tank truck deviates from the predetermined route according to the positioning information by the background monitoring device, and obtain the determination result returned by the background monitoring device. When it is determined that the tank truck deviates from the predetermined route according to the determination result, the field monitoring device can directly control the loudspeaker to issue the first voice prompt information, and send the first alarm information to the background monitoring device through the communication module.

[0057] Of course, after the background monitoring device determines that the tank truck deviates from the predetermined route according to the positioning information, the corresponding first voice prompt information can also be directly returned to the field monitoring device for playing by the field monitoring device.

[0058] The first voice prompt information can be a prompt information pre-set by the system, for prompting the tank truck to deviate from the predetermined route or to return to the predetermined route in time, etc. The first alarm information can include information for indicating that the tank truck deviates from the predetermined route, current position, current time, etc. After sending the first alarm information to the background monitoring device, the relevant personnel using the background monitoring device can return the corresponding shouting voice to the field monitoring device, and the field monitoring device can play the shouting voice to warn the driver.

[0059] Please refer to Figure 3 The tank truck transportation monitoring system provided by the utility model can further include an oil unloading valve position sensor 13, which is electrically connected with the field monitoring device, for collecting position information of the oil unloading valve and transmitting the position information of the oil unloading valve to the field monitoring device. Specifically, the sensor support 12 is fixed on the oil unloading valve assembly 1, and the oil unloading valve position sensor 13 can be installed on the sensor support 12. The position information collected by the oil unloading valve position sensor 13 can be opening degree information or opening and closing signals. The field monitoring device can also directly determine whether the oil unloading valve is opened according to the received position information of the oil unloading valve; the field monitoring device can also be used for receiving the position information of the oil unloading valve and the positioning information of the tank truck, and sending a second control signal to the loudspeaker and / or the communication module according to the position information of the oil unloading valve and the positioning information of the tank truck. In Figure 3 - Figure 7 The oil unloading valve assembly 1 further includes a cover 16 for plugging the outlet of the oil unloading valve. When the transported liquid is unloaded through the oil unloading valve assembly 1, the liquid can flow from the butterfly valve mechanism 14 to the cover 16.

[0060] The second control signal can be a signal for controlling the loudspeaker to give a second voice prompt information, or can be a signal for controlling the communication module to send a second alarm information to the background monitoring device.

[0061] Specifically, when it is determined according to the received position information of the unloading valve and the positioning information of the tank car that the opening site of the unloading valve is not at the predetermined site, the on-site monitoring device can control the loudspeaker to give a second voice prompt information, and send a second alarm information to the background monitoring device through the communication module.

[0062] Similarly, whether the opening site of the unloading valve is at the predetermined site can be determined by the background monitoring device or by the on-site monitoring device.

[0063] The second voice prompt information can be a prompt information preset by the system, for prompting that the opening site of the unloading valve is not at the predetermined site or that the unloading valve needs to be closed immediately, etc. The second alarm information can include information for indicating that the opening site of the unloading valve is not at the predetermined site, current position, current time, etc. After sending the second alarm information to the background monitoring device, a relevant staff using the background monitoring device can return a corresponding shouting voice to the on-site monitoring device, and the on-site monitoring device can play the shouting voice to warn the driver.

[0064] The tank car transportation monitoring system in the embodiment of the utility model can further include a manhole cover position sensor, the manhole cover position sensor is electrically connected with the on-site monitoring device, is used for collecting position information of the manhole cover, and transmits the position information of the manhole cover to the on-site monitoring device;The position information collected by the manhole cover position sensor can be opening degree information, or can be opening and closing signal. The on-site monitoring device can further determine whether the manhole cover is opened according to the received position information of the manhole cover;The on-site monitoring device can further be used for receiving the position information of the manhole cover and the positioning information of the tank car, and sending a third control signal to the loudspeaker and / or the communication module according to the position information of the manhole cover and the positioning information of the tank car.

[0065] The third control signal can be a signal for controlling the loudspeaker to give a third voice prompt information, or can be a signal for controlling the communication module to send a third alarm information to the background monitoring device. Specifically, when it is determined according to the received position information of the manhole cover and the positioning information of the tank car that the opening site of the manhole cover is not at the predetermined site, the on-site monitoring device can control the loudspeaker to give a third voice prompt information, and send a third alarm information to the background monitoring device through the communication module.

[0066] Of course, the predetermined site corresponding to the opening site of the manhole cover can be different from the predetermined site corresponding to the opening site of the unloading valve.

[0067] Similarly, determining whether the opening location of the manhole cover is at the predetermined location can be made by the back-end monitoring device or by the on-site monitoring device.

[0068] The third voice prompt can be a pre-set system message, used to indicate that the manhole cover is not in the designated location or needs to be closed immediately. The third alarm message can include information indicating that the manhole cover is not in the designated location, the current location, and the current time. After sending the third alarm message to the backend monitoring device, the relevant personnel using the backend monitoring device can send a corresponding voice message back to the on-site monitoring device, which can then play the message to alert the driver.
