If leakage occurs, some may produce volatile toxic gases, some may corrode the highway surface, and some may be flammable and explosive.

[0003] Certain chemical liquids cannot be directly measured using certain electronic devices. Furthermore, many liquid level measurement devices are only capable of measuring static levels. Therefore, existing technologies cannot dynamically measure the level of liquids in motion, making it impossible to accurately monitor the actual level of liquids during transportation or while a vehicle is in motion. If abnormal leakage or spillage occurs, it is typically only discovered after the fact, requiring remedial measures.

[0004] Therefore, there is an urgent need for a transport container that can monitor the liquid level in real time during transportation. Summary of the Invention

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example like Figure 1 and Figure 2 As shown, in this embodiment, the smart core barrel capable of monitoring the liquid level includes: a barrel body 1, four liquid level transmitters 2 and a monitor.

[0022] The barrel 1 comprises an inner wall 11 and an outer wall 12. A monitoring liquid 15 is disposed between these two walls. The cross-section of the monitoring liquid 15 is circular, maximizing its effective monitoring area while minimizing the increase in barrel volume. This allows for a more pronounced liquid level during shaking. The monitoring liquid 15 is a safe, non-reactive liquid selected based on the material of the barrel 1.

[0023] In addition, at least one waterproof and breathable valve 17 is provided on the outer barrel wall 12, so that the monitoring liquid 15 is connected to the atmosphere, and the liquid level is in a free state without pressure and rises and falls naturally with the barrel body.

[0024] In this embodiment, the four liquid level transmitters 2 are evenly distributed around the circumference of the monitoring liquid in the shape of a circular ring; of course, a non-uniform distribution state is also possible. The liquid level transmitter 2 can be a magnetostrictive transmitter or a float level transmitter. These two transmitters belong to the existing technology and will not be described in detail. Taking the magnetostrictive transmitter as an example, the lower end of the probe rod of the magnetostrictive transmitter is fixed in the groove at the bottom between the inner barrel wall 11 and the outer barrel wall 12; the upper end of the magnetostrictive transmitter is provided with a cover plate 16, which closes the inner barrel wall 11 and the outer barrel wall 12 to ensure that the monitoring liquid 15 does not leak out. The magnetic float 21 of the magnetostrictive transmitter fluctuates with the monitoring liquid 15, so that the liquid level height of the monitoring liquid 15 at that point can be obtained.

[0025] In this embodiment, the monitor can be built into the barrel 1. The monitor can set its coordinate origin as needed, with the center point at the bottom of the inner barrel wall 11 serving as the coordinate origin, i.e., (0, 0). The monitor stores the position information of each liquid level transmitter 2, namely, its X and Y coordinates. These two coordinates are fixed and unchanging when the magnetostrictive transmitter is installed on the barrel 1.

[0026] The Z value of the liquid level transmitter 2 changes continuously as the magnetic float rises and falls with the monitoring liquid 15. Figure 3 As shown, if the barrel body 1 is tilted, the magnetic float 21 of the magnetostrictive transmitter at different positions will present different heights. The position of the magnetic float 21 is the height value of the monitoring liquid 15, that is, the Z coordinate value.

[0027] The liquid level transmitter 2 provides the Z coordinate of the corresponding position to the monitor. The monitor can then obtain the (X, Y, Z) coordinate values ​​of the point in the monitoring liquid where each magnetostrictive transmitter is located. Based on the existing technology that can calculate a surface from three points that are not on a straight line, the monitor calculates the equation for the plane position β of the monitoring liquid 15. It should be noted that the coordinate system is based on the center point of the bottom of the inner barrel wall 11 as the coordinate origin, that is, a relative coordinate system of (0, 0, 0). As the barrel body 1 transforms, the specific absolute position will change.

[0028] In order to more intuitively reflect the plane position β, the monitor sets the bottom of the inner barrel wall 11 as the reference plane O, that is, the Z value is 0. The monitor calculates the current monitoring liquid level inclination E through the plane position β and the reference plane O. Due to the effect of gravity, whether it is the monitoring liquid 15 or the liquid stored in the barrel, the liquid level always remains horizontal. The so-called inclination angle is the angle between the liquid level and the inclined barrel body. Therefore, the inclination of the liquid stored in the barrel and the inclination of the monitoring liquid level are consistent. Figure 3 shown.

[0029] In this embodiment, the height difference between the liquid stored in the barrel and the height of the monitoring liquid 15 may vary. The monitor can receive the Z value of the current stored liquid. This value is the current liquid level height of the stored liquid. It can be calculated based on the loading volume, density, and parameters of the barrel; it can also be measured after the liquid is loaded into the barrel. In a stable state, the Z value of the liquid level transmitter 2 is theoretically consistent. If there is a slight difference, the average Z value of the four positions can be taken to calculate the height difference Δh between the stored liquid and the monitoring liquid 15. Of course, this height difference Δh between the stored liquid and the monitoring liquid 15 can be obtained directly from the host computer.

[0030] The monitor also calculates the planar position α of the stored liquid based on the planar position β of the monitoring liquid 15 and the height difference Δh. This is the planar position of the stored liquid. It should be noted that when the liquid surface and the barrel are tilted, the area of ​​the liquid surface changes. In theory, Δh will change after the tilt, but this error is completely acceptable. The calculated planar position α can also be used as the stored liquid surface.

[0031] As a derivative of the smart barrel application that can monitor liquid levels, the monitor can regard the plane position α as a horizontal plane, reversely calculate the position of the bottom of the inner barrel wall 11, convert it into a graphic, and display it on the configured display device, allowing people to see the current status of the barrel body more intuitively.

[0032] In this embodiment, the monitor is preset with a rated value of the liquid level inclination; when the current liquid level inclination E calculated by the monitor is greater than the rated value of the liquid level inclination, the monitor issues a tilt alarm message to remind the driver or operator to slow down. If the alarm continues, it is necessary to stop the vehicle or shut down the machine for inspection to determine whether a collision has occurred and the barrel body cannot return to a horizontal position.

[0033] In this embodiment, the monitor is pre-set with a safety height rating for each level transmitter 2. When the height information obtained by the monitor regarding the monitoring liquid 15 exceeds the safety height rating, the monitor issues a height alarm. The safety height of the level transmitter 2 indicates that the conveyed liquid may or has reached a level at which it may overflow, alerting the driver or operator to stop the machine or shut down for inspection.

[0034] Theoretically, only three level transmitters 2 are needed for monitoring. However, if a level transmitter 2 malfunctions during transport, meaning the Z value at a specific position is incorrect, this could lead to an overall calculation error and an incorrect judgment. To prevent this, four level transmitters 2 are installed. Four data sets can be combined to perform a maximum of four calculations. The monitor calculates the plane position β three or four times based on the four data sets from the four level transmitters 2. If the error in the three or four plane position β values ​​is less than the standard error value, the average of these three or four plane position β values ​​is used as the final output value, indicating that all level transmitters 2 are functioning properly. If the error in the three or four plane position β values ​​is greater than the standard error value, the plane position β with the greatest inclination is used as the final output value, and an alarm is issued. This indicates that the Z value of one of the level transmitters 2 is incorrect. If the problem cannot be immediately identified, the highest inclination is used as the primary criterion. Once the inspection conditions are met, repairs are immediately performed.

[0035] In this embodiment, the monitor can be built into the barrel 1, and all data received and calculated are transmitted to the upper control device via wireless transmission. Of course, the monitor is set on the upper control device, and after receiving the height position information of the monitoring liquid 15 detected by the liquid level transmitter 2 via wireless transmission, it performs corresponding calculations.

[0036] It should be noted that the barrel body can be equipped with mechanical structures such as lifting ears and barrel covers according to operational requirements; the barrel body structure is not limited to that shown in the embodiment.

[0037] The embodiments described above are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
