[0047] Figure 2 FIG. 1 is a partial structural diagram of a tanker according to an embodiment of the present application. Figure 2As shown, the solution provided by the present application is used for monitoring a tank truck, which includes a tank body 3 for loading edible oil or other liquids, and a manhole is provided on the top of the tank body 3, and the manhole is used to load edible oil and other transport objects. A manhole cover assembly 2 is installed at each manhole of the tank body 3, and the manhole cover assembly includes a manhole cover; an oil unloading valve is installed at the bottom of the rear end cover 31 of the tank body 3, and in the present application, the oil unloading valve is Figure 2 The oil unloading valve assembly 1 in the tank truck transport monitoring system provided in the present application includes an oil unloading valve monitoring camera 101, which is fixed on the tank body 3 of the tank truck. Specifically, the oil unloading valve monitoring camera 101 can be installed on the top of the rear end cover 31 of the tank body, and the oil unloading valve monitoring camera 101 needs to be installed toward the oil unloading valve assembly 1, that is, the oil unloading valve is located in the field of view of the oil unloading valve monitoring camera 101, and the sensing side of the oil unloading valve monitoring camera 101 is facing the oil unloading valve installed on the tank body 3, so as to make a video record of the use of the oil unloading valve.

[0048] The tanker transport monitoring system provided by the present application may also include a background monitoring device and a manhole monitoring camera 201, which is fixed on the tank body 3 of the tanker, and the sensing side of the manhole monitoring camera 201 faces the manhole cover installed at the manhole of the tank body, that is, the sensing side of the manhole monitoring camera 201 faces the manhole cover assembly 2, so that the manhole cover assembly 2 is located in the field of view of the manhole monitoring camera 201, so as to record the use of the manhole cover by video. The unloading valve monitoring camera 101 is arranged at a distance from the manhole monitoring camera 201.

[0049] The tanker transport monitoring system provided in the present application may also include a field monitoring device, which is located on the tanker, for example, it can be installed in the cab of the tanker. The field monitoring device may have a display screen, for example, it may be a display-control integrated screen with display and control functions. The field monitoring device is electrically connected to the manhole monitoring camera and the oil unloading valve monitoring camera respectively (for example, connected by a wiring harness), and the field monitoring device includes a communication module (such as a 4G or 5G mobile communication module) that can communicate wirelessly with the background monitoring device; the field monitoring device is used to obtain the video recorded by the manhole monitoring camera and the oil unloading valve monitoring camera, and transmit the obtained video to the background monitoring device through the communication module. The field monitoring device can transmit the obtained video to the background monitoring device in real time through the communication module, or it can first store the obtained video in a local memory, and then, when necessary, transmit the video stored in the local memory and / or the video obtained in real time to the background monitoring device. The capacity of the local memory is usually limited. Therefore, the local memory can only store videos of a predetermined length or a predetermined size. When the video stored in the local memory reaches the predetermined length or size, if it is necessary to continue storing videos, the latest acquired video data can be used to overwrite the earliest video data stored in the local memory in sequence, so that the data stored in the local memory is always the latest video data.

[0050] The on-site 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.

[0051] Whether the manhole cover or oil unloading valve is open can be judged by AI recognition of the video collected by the corresponding monitoring camera. AI recognition can be performed by the on-site monitoring device, or the on-site monitoring device can transmit the video to the background monitoring device, which can perform AI recognition.

[0052] Since the amount of video data collected by the camera is very large, performing AI recognition on all video frames will consume a lot of computing resources. In order to save computing resources, video frames can be obtained from the video frames collected by each camera at predetermined intervals (such as 5 seconds) through sampling, and then AI can be used for recognition.

[0053] When a manhole cover or an oil unloading valve is detected to be opened, the on-site monitoring device can transmit only the video data collected by the camera responsible for monitoring the manhole cover or the oil unloading valve to the background monitoring device. It can also 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.

[0054] When the manhole cover or the oil unloading valve is opened, the on-site monitoring device can transmit the real-time acquired video data to the background monitoring device through the communication module; in order to achieve more reliable and comprehensive monitoring, the video data of a predetermined time recorded before the current time and the real-time acquired video data can also be transmitted to the background monitoring device.

[0055] Of course, whether the manhole cover or the oil unloading valve is opened can also be determined by other methods; for example, position sensors for monitoring the positions of the manhole covers and the oil unloading valves can be respectively installed on the tank body 3.

[0056] Figure 3 is a three-dimensional diagram of an oil unloading valve assembly according to an embodiment of the present application; Figure 4 It is a front view of an oil unloading valve assembly according to an embodiment of the present application; Figure 5 is a top view of an oil unloading valve assembly according to an embodiment of the present application; Figure 6 It is a right side view of an oil unloading valve assembly according to one embodiment of the present application; Figure 7 It is a left side view of an oil unloading valve assembly according to an embodiment of the present application.

[0057] See also Figure 3-Figure 7 As shown, the oil unloading valve, namely the oil unloading valve assembly 1, comprises a pneumatic actuator 11, a butterfly valve mechanism 14 and a valve handle 15 for controlling the pneumatic actuator 11, the butterfly valve mechanism 14 comprises a butterfly flange 141, a butterfly plate and a return device 142 for constraining the position of the butterfly plate, the butterfly plate is fixedly rotatably connected in the butterfly flange 141, and the pneumatic actuator 11 is transmission-connected with the return device 142. The oil unloading valve assembly 1 can be fixedly connected to the oil outlet of the tank body 3 through the butterfly flange 141. The return device 142 can be a spring. The pneumatic actuator 11 can include a cylinder 111 and an induction bracket 112, the cylinder 111 and the induction bracket 112 are connected through a movable key, the cylinder 111 can drive the movement of the induction bracket 112 by driving the movement of the movable key, thereby driving the return device 142 to perform a corresponding action (such as spring compression), and then driving the rotation of the butterfly plate to realize the opening or closing of the oil unloading valve.

[0058] The on-site monitoring device may also include a speaker and a positioning module for positioning the tank truck. The on-site monitoring device is also used to obtain the positioning information of the tank truck through the positioning module, and when it is determined that the tank truck deviates from the predetermined route according to the positioning information, the speaker is controlled to send a first voice prompt message, and a first alarm message is sent to the background monitoring device through the communication module. The on-site monitoring device may include one or more speakers, and may also include one or more positioning modules.

[0059] The on-site monitoring device can directly determine whether the tank truck deviates from the scheduled route based on the positioning information, or it can first send the positioning information to the background monitoring device, which will determine whether the tank truck deviates from the scheduled route based on the positioning information and obtain the determination result returned by the background monitoring device. When the on-site monitoring device determines that the tank truck deviates from the scheduled route based on the determination result, it can directly control the speaker to issue a first voice prompt message and send a first alarm message to the background monitoring device through the communication module.

[0060] Of course, after determining that the tank truck has deviated from the predetermined route according to the positioning information, the background monitoring device can also directly return the corresponding first voice prompt information to the on-site monitoring device, which will play it.

[0061] The first voice prompt information may be a prompt information preset by the system, which is used to prompt the tank truck to deviate from the predetermined route or to return to the predetermined route in time. The first alarm information may include information indicating that the tank truck deviates from the predetermined route, the current location, the 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 on-site monitoring device, and the on-site monitoring device can play the shouting voice to warn the driver.

[0062] See also Figure 3 As shown, the tanker transport monitoring system provided by the present application may also include an oil unloading valve position sensor 13, and the oil unloading valve position sensor 13 is electrically connected to the on-site monitoring device, and is used to collect the position information of the oil unloading valve, and transmit the position information of the oil unloading valve to the on-site monitoring device. Specifically, a sensor bracket 12 is fixed on the oil unloading valve assembly 1, and the oil unloading valve position sensor 13 can be installed on the sensor bracket 12. The position information collected by the oil unloading valve position sensor 13 can be opening information or an opening and closing signal. The on-site monitoring device can also directly determine whether the oil unloading valve is open based on the received position information of the oil unloading valve; the on-site monitoring device can also be used to receive the position information of the oil unloading valve and the positioning information of the tanker, and when it is determined that the opening location of the oil unloading valve is not at the predetermined location based on the received position information of the oil unloading valve and the positioning information of the tanker, the speaker is controlled to send a second voice prompt message, and a second alarm message is sent to the background monitoring device through the communication module. Figure 3-Figure 7 In the embodiment, the oil unloading valve assembly 1 further comprises a sealing cover 16, which is used to block 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 sealing cover 16.

[0063] Similarly, whether the opening location of the oil unloading valve is at the predetermined location can be determined by the background monitoring device or by the on-site monitoring device.

[0064] The second voice prompt information may be a prompt information preset by the system, which is used to prompt that the opening location of the oil unloading valve is not at the predetermined location or that the oil unloading valve needs to be closed immediately, etc. The second alarm information may include information indicating that the opening location of the oil unloading valve is not at the predetermined location, the current location, the current time, etc. After sending the second alarm information to the background monitoring device, the relevant personnel using the background monitoring device can return the corresponding shouting voice to the on-site monitoring device, and the on-site monitoring device can play the shouting voice to warn the driver.

[0065] The tanker transport monitoring system in the embodiment of the present application may also include a manhole cover position sensor, which is electrically connected to the on-site monitoring device and is used to collect the position information of the manhole cover and transmit the position information of the manhole cover to the on-site monitoring device; the position information collected by the manhole cover position sensor may be opening information or an opening and closing signal. The on-site monitoring device may also determine whether the manhole cover is open based on the received position information of the manhole cover; the on-site monitoring device may also be used to receive the position information of the manhole cover and the positioning information of the tanker, and when it is determined that the opening location of the manhole cover is not at the predetermined location based on the received position information of the manhole cover and the positioning information of the tanker, the speaker is controlled to issue a third voice prompt message, and a third alarm message is sent to the background monitoring device through the communication module.

[0066] Of course, the predetermined location corresponding to the opening location of the manhole cover and the predetermined location corresponding to the opening location of the oil discharge valve may be different.

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

[0068] The third voice prompt information may be a prompt information preset by the system, which is used to prompt that the opening location of the manhole cover is not at the predetermined location or that the manhole cover needs to be closed immediately, etc. The third alarm information may include information indicating that the opening location of the manhole cover is not at the predetermined location, the current location, the current time, etc. After sending the third alarm information to the background monitoring device, the relevant personnel using the background monitoring device can return the corresponding shouting voice to the on-site monitoring device, and the on-site monitoring device can play the shouting voice to warn the driver.

[0069] In the above embodiments, each voice prompt information may be the same or different; each alarm information may be the same or different.

[0070] The tank body 3 may have a plurality of manholes, and the tank truck may include a plurality of manhole covers, each of which is installed at a manhole of the tank body. The plurality of manholes may be evenly opened at the top of the tank body 3.

[0091] The present application also provides a tank truck transportation monitoring method.

[0092] Fig.12 1 shows a flow chart of a tanker transport monitoring method according to an embodiment of the present application. The method can be executed by the on-site monitoring device in the above embodiment. Fig.12 As shown, the tank truck transportation monitoring method may specifically include the following steps:

[0093] Step 1210, obtaining the position information of the manhole cover and the position information of the oil unloading valve, the manhole cover is installed at the manhole of the tank body of the tank truck, and the oil unloading valve is installed on the tank body of the tank truck.

[0094] The position information of the manhole cover can be collected by the manhole cover position sensor, and the position information of the oil unloading valve can be collected by the oil unloading valve position sensor. The position information of the manhole cover and the oil unloading valve can be opening information or opening and closing information.

[0095] Step 1220, when it is determined based on the position information of the manhole cover that the manhole cover is open, at least a first video recorded for the use of the manhole cover is obtained, and the first video is transmitted to the background monitoring device.

[0096] Before executing this step, it can be determined whether the manhole cover is open. The location information of the manhole cover can be sent to a background monitoring device, which determines whether the manhole cover is open and returns the determination result to the on-site monitoring device; the on-site monitoring device can also directly determine whether the manhole cover is open based on the location information of the manhole cover.

[0097] The first video recorded for the use of the manhole cover can be obtained through the manhole monitoring camera. When there are multiple manhole covers and only some of the manhole covers (such as one manhole cover) are opened, the first video recorded for the use of the opened manhole cover can be obtained only through the manhole monitoring camera corresponding to the opened manhole cover. Of course, the collected video can also be obtained as the first video through a larger number of cameras fixed on the tank body, including the manhole monitoring camera corresponding to the opened manhole cover.

[0098] In one embodiment of the present application, when it is determined that the manhole cover is open based on the position information of the manhole cover, at least a first video recorded for the use of the manhole cover is obtained, including: when it is determined that the manhole cover is open based on the position information of the manhole cover, start video recording of the use of the manhole cover to obtain the first video.

[0099] When it is determined that the manhole cover is open according to the position information of the manhole cover, a start recording instruction may be sent to the manhole monitoring camera corresponding to the manhole cover, thereby recording and obtaining the first video.

[0100] Of course, each manhole monitoring camera can also continue to record the use of the manhole cover, and store the recorded video in the local storage space of the on-site monitoring device. When the on-site monitoring device determines that the manhole cover is open, it can obtain the video recorded by the manhole monitoring camera corresponding to the manhole cover after the current time from the local storage space as the first video; in order to obtain a more comprehensive monitoring video, when the on-site monitoring device determines that the manhole cover is open, it can obtain the video recorded by the manhole monitoring camera corresponding to the manhole cover after a predetermined time from the local storage space as the first video, wherein the predetermined time is before the current time, and the predetermined time is separated from the current time by a predetermined length of time.

[0101] Step 1230, when it is determined based on the position information of the oil unloading valve that the oil unloading valve is open, at least a second video recorded for the use of the oil unloading valve is obtained, and the second video is transmitted to the background monitoring device.

[0102] Before executing this step, it can be determined whether the oil unloading valve is open. The position information of the oil unloading valve can be sent to the background monitoring device, which determines whether the oil unloading valve is open and returns the determination result to the on-site monitoring device; the on-site monitoring device can also directly determine whether the oil unloading valve is open based on the position information of the oil unloading valve.

[0103] The second video recorded for the use of the oil unloading valve can be obtained through the oil unloading valve monitoring camera. Of course, the collected video can also be obtained as the second video through a larger number of cameras including the oil unloading valve monitoring camera and at least one manhole monitoring camera.

[0104] In one embodiment of the present application, when it is determined based on the position information of the oil unloading valve that the oil unloading valve is open, at least a second video recorded for the use of the oil unloading valve is obtained, including: when it is determined based on the position information of the oil unloading valve that the oil unloading valve is open, start video recording of the use of the oil unloading valve to obtain a second video.

[0105] When it is determined that the oil unloading valve is open according to the position information of the oil unloading valve, a start recording instruction may be sent to the oil unloading valve monitoring camera corresponding to the oil unloading valve, thereby recording a second video.

[0106] Of course, the oil unloading valve monitoring camera can also continuously record the use of the oil unloading valve, and store the recorded video in the local storage space of the on-site monitoring device. When the on-site monitoring device determines that the oil unloading valve is open, it can obtain the video recorded by the oil unloading valve monitoring camera after the current time from the local storage space as the second video; in order to obtain a more comprehensive monitoring video, when the on-site monitoring device determines that the oil unloading valve is open, it can obtain the video recorded by the oil unloading valve monitoring camera after a predetermined time from the local storage space as the second video, wherein the predetermined time is before the current time, and the predetermined time is separated from the current time by a predetermined duration.

[0107] When the manhole cover or the oil unloading valve is opened, the on-site monitoring device can play the video recorded on the opened manhole cover or the oil unloading valve, and send out a corresponding alarm to remind the driver.

[0108] Of course, in order to carry out more comprehensive monitoring, multiple manhole monitoring cameras can be set for each manhole cover, and different manhole monitoring cameras are located at different positions and face the corresponding manhole covers from different angles; multiple oil unloading valve monitoring cameras can also be set for the oil unloading valve, and different oil unloading valve monitoring cameras are located at different positions and face the oil unloading valve from different angles.

[0109] When multiple surveillance cameras are set corresponding to the manhole cover or the oil unloading valve, when the manhole cover or the oil unloading valve is not opened, video recording can be performed through some surveillance cameras (such as one surveillance camera) corresponding to the manhole cover or the oil unloading valve, and the recorded video is stored in the local storage space of the on-site monitoring device; when the manhole cover or the oil unloading valve is opened, video recording can be performed through all surveillance cameras (multiple surveillance cameras) corresponding to the manhole cover or the oil unloading valve, and the recorded video is transmitted to the background monitoring device.

[0110] After the manhole cover or the oil unloading valve is opened, if the opened manhole cover or the oil unloading valve is closed again, the video recorded for the use of the opened manhole cover or the oil unloading valve can continue to be transmitted to the background monitoring device, and after a predetermined time period, the recorded video can be stopped from being transmitted to the background monitoring device to ensure the comprehensiveness of the monitoring.

[0112] Step 1310, obtaining the location information of the tank truck.

[0113] The positioning information can be obtained through positioning modules such as the GPS module and Beidou module in the on-site monitoring device, thereby obtaining the positioning information of the tank truck.

[0114] Step 1320: When it is determined based on the positioning information that the tank truck deviates from the predetermined route, a first voice prompt message is issued, and a first alarm message is sent to the background monitoring device.

[0115] The positioning information can be sent to the background monitoring device, which determines whether the tank truck deviates from the predetermined route based on the positioning information and returns the determination result to the on-site monitoring device; the on-site monitoring device can also directly determine whether the tank truck deviates from the predetermined route based on the positioning information.

[0116] The scheduled routes for different tank trucks may be different. A corresponding scheduled route may be configured for each tank truck.

[0117] The point on the planned route closest to the position indicated by the positioning information can be determined, and then the distance between the point and the position indicated by the positioning information can be determined. If the distance exceeds a predetermined distance threshold, it is determined that the tank truck has deviated from the planned route.

[0118] The first voice prompt information and the first alarm information have been introduced in the aforementioned embodiments and will not be described again here.

[0119] Fig.14 A flow chart showing a second monitoring strategy of a tanker transport monitoring method according to an embodiment of the present application is shown. Fig.14 As shown, the tank truck transportation monitoring method may further include the following steps:

[0120] Step 1410: When it is determined that the oil unloading valve is open according to the position information of the oil unloading valve, the positioning information of the tank truck is obtained.

[0121] Before executing this step, it can be determined whether the oil unloading valve is open. The position information of the oil unloading valve can be sent to the background monitoring device, which determines whether the oil unloading valve is open and returns the determination result to the on-site monitoring device; the on-site monitoring device can also directly determine whether the oil unloading valve is open based on the position information of the oil unloading valve.

[0122] Step 1420: When it is determined based on the positioning information that the tank truck is not at the position where the oil unloading valve is allowed to be opened, a second voice prompt message is issued, and a second alarm message is sent to the background monitoring device.

[0123] The permitted opening position of the oil unloading valve can be configured in advance, and the permitted opening positions of the oil unloading valves of different tank trucks can be different. Whether the tank truck is in the permitted opening position of the oil unloading valve can be determined by judging whether the positioning information is located within a circular area with the permitted opening position of the oil unloading valve as the center and a predetermined length as the radius. Whether the tank truck is in the permitted opening position of the oil unloading valve can be determined by an on-site monitoring device or a background monitoring device.

[0124] The second voice prompt information and the second alarm information have been introduced in the aforementioned embodiments and will not be described again here.

[0126] Step 1510, when it is determined that the manhole cover is open based on the position information of the manhole cover, the positioning information of the tank truck is obtained.

[0127] Before executing this step, it can be determined whether the manhole cover is open. The location information of the manhole cover can be sent to a background monitoring device, which determines whether the manhole cover is open and returns the determination result to the on-site monitoring device; the on-site monitoring device can also directly determine whether the manhole cover is open based on the location information of the manhole cover.

[0128] Step 1520: When it is determined based on the positioning information that the tank truck is not at the location where the manhole cover is allowed to be opened, a third voice prompt message is issued, and a third alarm message is sent to the background monitoring device.

[0129] The permitted opening location of the manhole cover can be configured in advance, and the permitted opening locations of the manhole covers of different tank trucks can be different; even for the same tank truck, the permitted opening locations of different manhole covers can be different; for the same tank truck, the permitted opening location of the manhole cover and the permitted opening location of the oil unloading valve can also be different. Whether the tank truck is in the permitted opening location of the oil unloading valve can be determined by judging whether the positioning information is located within a circular area with the permitted opening location of the manhole cover as the center and a predetermined length as the radius. Whether the tank truck is in the permitted opening location of the manhole cover can be determined by an on-site monitoring device or a background monitoring device.
