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

[0021] Example

[0022] like Figure 1 and Figure 2 As shown in this embodiment, the smart tank that can monitor the liquid level includes: a tank body 1, four liquid level transmitters 2, and a monitor.

[0023] The tank body 1 includes an inner tank wall 11 and an outer tank wall 12; a monitoring liquid 15 is disposed between the inner tank wall 11 and the outer tank wall 12; the cross-section of the monitoring liquid 15 is annular, maximizing the effective monitoring area of ​​the monitoring liquid 15 while minimizing the increase in tank body volume, resulting in a more obvious liquid level fluctuation when shaken. The monitoring liquid 15 is selected based on the material of the tank body 1, using a safe type of liquid that is not prone to reaction.

[0024] In addition, at least one waterproof and breathable valve 17 is installed on the outer barrel wall 12, so that the monitoring liquid 15 is connected to the atmosphere and the liquid surface is in a free state without pressure, and rises and falls naturally with the barrel body.

[0025] In this embodiment, four level transmitters 2 are evenly distributed circumferentially around the location of the monitored liquid in a circular pattern; however, a non-uniform distribution is also possible. The level transmitters 2 can be magnetostrictive transmitters or float level transmitters, both of which are existing technologies and will not be described in detail. Taking a magnetostrictive transmitter as an example, the lower end of the probe of the magnetostrictive transmitter is fixed in a groove at the bottom between the inner barrel wall 11 and the outer barrel wall 12; a cover plate 16 is provided at the upper end of the magnetostrictive transmitter to seal the inner barrel wall 11 and the outer barrel wall 12, ensuring that the monitored liquid 15 does not leak out. The magnetic float 21 of the magnetostrictive transmitter fluctuates with the rise and fall of the monitored liquid 15, thereby obtaining the liquid level height at that point in the monitored liquid 15.

[0026] In this embodiment, the monitor can be built-in on the barrel 1. The monitor can set the coordinate origin as needed, taking the center point of the inner barrel wall 11 bottom as the coordinate origin, i.e. (0, 0, 0). The monitor stores the position information of each liquid level transmitter 2, i.e. X, Y coordinates, which are determined values when the magnetostrictive transmitters are installed on the barrel 1.

[0027] The Z value of the liquid level transmitter 2 is constantly changing with the fluctuation of the magnetic float with the monitored liquid 15, as shown in Figure 3 If the barrel 1 is tilted, the magnetic floats 21 of the magnetostrictive transmitters at different positions will present different heights, and the position of the magnetic float 21 is the height value of the monitored liquid 15, i.e. the Z coordinate value.

[0028] The liquid level transmitter 2 provides the obtained Z coordinate of the corresponding position to the monitor. The monitor can obtain the (X, Y, Z) coordinate value of the point of the monitored liquid by each magnetostrictive transmitter. According to the prior art that three points on a non-straight line can calculate a plane, the monitor calculates the equation of the plane position β of the monitored liquid 15. It should be noted that the coordinate system is a relative coordinate system with the center point of the inner barrel wall 11 bottom as the coordinate origin, i.e. (0, 0, 0), and the specific absolute position will change with the barrel 1.

[0029] In order to more intuitively reflect the plane position β, the monitor sets the inner barrel wall 11 bottom as the reference surface O, i.e. the Z value is 0. The monitor calculates the current monitored liquid surface inclination E through the plane position β and the reference surface O. Due to the effect of gravity, whether it is the monitored liquid 15 or the liquid stored in the barrel, the liquid surface always remains horizontal, and the so-called inclination angle is the angle between the liquid surface and the tilted barrel, so the inclination of the liquid stored in the barrel and the inclination of the monitored liquid surface are consistent, as shown in Figure 3 .

[0030] In this embodiment, the height of the liquid stored in the barrel each time and the height of the monitored liquid 15 can have different height differences. The monitor can receive the Z value of the current stored liquid, which is the liquid level height of the current stored liquid, which can be calculated according to the filling amount, density and parameters of the barrel; or it can be measured after the liquid is filled into the barrel. In a stable state, the Z value of the liquid level transmitter 2 is theoretically consistent, and if there is a slight difference, the average value Z of four positions can be taken to calculate the height difference Δh between the stored liquid and the monitored liquid 15. Of course, this height difference Δh between the stored liquid and the monitored liquid 15 can be directly obtained from the upper computer.

[0031] The monitor also calculates the plane position a of the storage liquid according to the plane position β and the height difference Δh of the monitoring liquid 15. It is to be noted that the area of the liquid surface changes after the barrel body is tilted, and theoretically the height difference Δh changes after the barrel body is tilted, but the error is within an acceptable range. The plane position a calculated by the monitor can be regarded as the storage liquid surface.

[0032] As an application derived from the smart chip barrel capable of monitoring the liquid level, the monitor can regard the plane position a as a horizontal plane, reversely calculate the position of the bottom of the inner barrel wall 11, convert the position into a graph, and display the graph on the configured display device, so that people can more intuitively see the current state of the barrel body.

[0033] In the embodiment, the monitor is preset with a rated value of the liquid surface inclination; when the current liquid surface inclination E calculated by the monitor is greater than the rated value of the liquid surface inclination, the monitor sends an inclination alarm information to remind the driver or the operator to slow down, and if the alarm continues, the driver or the operator needs to stop the vehicle or the machine for inspection to determine whether the barrel body cannot return to the horizontal position due to a collision.

[0034] In the embodiment, the monitor is preset with a rated value of the safe height of each liquid level transmitter 2; when the height position information of the monitoring liquid 15 obtained by the monitor is greater than the rated value of the safe height, the monitor sends a height alarm information. The safe height of the liquid level transmitter 2 represents the height at which the transported liquid may or has reached the overflow, reminding the driver or the operator to stop the vehicle or the machine for inspection.

[0035] In theory, three liquid level transmitters 2 can achieve monitoring. However, if one of the liquid level transmitters 2 fails during the transfer, that is, the Z value of the position is incorrect, the entire calculation will be incorrect and the judgment will be incorrect. In order to prevent such events from occurring, four liquid level transmitters 2 are provided. Four sets of data can be arranged in combination to calculate the plane position β for a maximum of 4 times. The monitor calculates the plane position β for 3 to 4 times according to the four sets of data arranged in combination by the four liquid level transmitters 2. When the error of the plane position β calculated for 3 to 4 times is less than an error standard value, the average value of the plane position β calculated for 3 to 4 times is taken as the final output value; it is indicated that all the liquid level transmitters 2 are in a normal state. When the error of the plane position β calculated for 3 to 4 times is greater than the error standard value, the plane position β with the maximum inclination is taken as the final output value, and an alarm is prompted. In this case, it is indicated that the Z value of one of the liquid level transmitters 2 is incorrect, and if the problem cannot be checked immediately, the maximum inclination is used as the judgment standard. When the checking condition is met, the repair is carried out immediately.

[0036] In this embodiment, the monitor can be built in the barrel 1, receiving and calculating all the data obtained by wireless transmission to the upper control device. Of course, the monitor is set in the upper control device, and after receiving the monitoring liquid 15 height position information monitored by the liquid level transmitter 2 through wireless transmission, corresponding calculation is performed.

[0037] It should be noted that the barrel can be configured with lifting lugs, barrel covers and other mechanical structures according to the operation requirements; the barrel structure is not limited to the embodiment.

[0038] The above-described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
