Tank lorry according to an embodiment of the present invention, as shown in Figure 1, the tank 10 may be mounted on the rear of the vehicle, the control unit 100 may be provided in the driver's seat.

The tank 10 may be provided with a plurality of partition walls 21 and 22 therein, and two partition walls are shown in FIG. 2, and the number of partition walls depends on the storage capacity of the tank 10 or the purpose of the user. You can also increase.

The compartment may be provided in plural, and in particular, the compartment may be determined by the number of partitions as the inner space of the tank 10 is partitioned by the partitions, and three compartments 31, 32, and 33 are illustrated in FIG. 2. ), Which means that there are two compartments, so there are three compartments.

Individual drain valves 41, 42, and 43 may be provided below each of the three compartments 31, 32, and 33, and may be selected from a plurality of individual drain valves 41, 42, and 43 by a user's operation. Either individual drain valve 41, 42, 43 can be opened. When the individual drain valve is open, the desired liquid can be drained.

In addition, the upper side of each of the three compartments (31, 32, 33) may be provided with individual vent valves (51, 52, 53). The plurality of individual vent valves 51, 52, and 53 may be opened and closed in cooperation with the individual drain valves 41, 42, and 43. For example, when an individual drain valve of a particular compartment is opened, the individual vent valve of that compartment can be opened, thereby keeping the drain of the liquid good by allowing external air to enter the deletion when the liquid is drained. have.

The drain line 12 may be connected to the plurality of individual drain valves 41, 42, and 43, and the drain line 12 may be provided with a drain valve 45. Thus, when the liquid is drained by opening any one of the plurality of individual drain valves 41, 42, 43, the liquid can finally be moved along the drain line 12, and the drain valve ( The liquid may be discharged to the outside by the opening of 45).

Meanwhile, the drain line 12 may have a gradient formed in a discharge direction, and thus liquid may not exist in a section from the individual drain valves 41, 42, 43 to the drain valve 45. More specifically, the liquid may flow out by gravity, or the remaining liquid inside the drain line 12 may evaporate or flow out while the drain valve 45 is opened, Even if the liquid passes through the drain line 12 in sequence, the liquid supply side can receive a liquid that maintains purity without mixing heterogeneous liquids.

In addition, a plurality of compartment valves 61 and 62 may be provided to open one of the three compartments 31, 32, and 33 to be connected to another compartment adjacent to the compartment, and the compartment valve may be opened by an opening request signal. 61 and 62 can be opened.

On the other hand, the compartment valves 61 and 22 may be solenoid valves, whereby when the switch is operated so that opening is required by the user, the opening request signal may be input and operated as an electrical signal.

In addition, the tank lorry and the tank lorry control method according to an embodiment of the present invention may include a control unit 100. The controller 100 may control whether the plurality of compartment valves 61 and 62 are opened or closed.

In more detail with respect to the control unit 100, the storage target liquid information stored in the three compartments 31, 32, and 33 may be input. And when the opening request signal is generated such that any one or all of the plurality of compartment valves 61 and 62 are opened, the information of the liquid stored in each of the compartments to be connected is the same, and is stored in each of the compartments to be connected. If the information of the liquid is different, the closed state can be maintained.

The tank lorry according to the embodiment of the present invention made as described above, when the opening of the compartment valve is required by the user's request, maintains the closed state when the liquid stored in the compartment to be connected is heterogeneous, and opens only when it is homogeneous. Inadvertent mixing of liquids can be prevented by the user's carelessness.

On the other hand, the tank lorry and the tank lorry control method according to an embodiment of the present invention, when any one of the plurality of individual drain valve (41, 42, 43) is opened and the liquid is emptied inside the specific compartment, The storage target liquid information may be deleted from the controller 100.

In general, a tank roller is known to be able to count the discharge flow rate when discharging the liquid, and also to count the stored capacity when storing the liquid in the tank.

That is, the fact that the liquid is emptied when the liquid is emptied in a specific compartment can be easily recognized by known techniques, and such information can be provided to the controller 100.

The user inputs the liquid into the control unit 100 immediately after the liquid is filled into the empty compartment. As a result, information on the newly filled liquid can be input again so that a correct judgment can be made when the opening and closing of the compartment valve is requested.

Hereinafter, with reference to the accompanying drawings, it will be described in more detail in each step with respect to the control method of the tank lorry according to an embodiment of the present invention.

First Step S1: The first step S1 is a step of inputting storage target liquid information stored in a plurality of compartments. The user has the opportunity to confirm once again which liquid is filled in or which liquid is filled in each compartment 31, 32, 33 of the tank 10. Meanwhile, the controller 100 may store the type of liquid in advance, and when the user inputs the type of liquid, the user may select the type of the liquid stored in advance from the list.

Second Step S2: The second step S2 may be a step in which opening of one or all of the plurality of compartment valves 61 and 62 is required. The user can operate the control unit 100 to open the desired compartment valve.

Third Step S3: The third step S3 is a step of determining whether liquid storage information of compartments to be connected to each other is the same. In general, the person who fills a liquid and the person who receives the liquid may be the same or different. Other people may not know what kind of liquid is stored in the tank. And even the same person may misunderstand the type of liquid during a long distance travel.

Fourth step S4: The fourth step S4 is a step of opening a compartment valve for which opening is required if the storage target liquid information of the compartments to be connected to each other is the same.

Fifth Step S5: A fifth step S5 is a step of maintaining the required compartment valve to be closed when the storage target liquid information of the compartments to be connected to each other is different.

Therefore, the tank lorry control method according to the embodiment of the present invention can prevent a problem that may occur due to the opening of the compartment valve, and in particular, when the compartment valve is opened, the judgment is made based on the information already input, without being judged by a person. This can prevent the mixing of heterogeneous liquids.

On the other hand, the tank lorry control method according to an embodiment of the present invention may further include a sixth step (S6) for outputting a warning message after maintaining the compartment valve in the closed state in the fifth step (S5). .

That is, the user can know that the compartment valve is not opened when the compartment valve is not opened even when the compartment valve is operated.

The warning message may be output as a siren, an alarm, a voice, or the like. The warning message may be output as a text or a figure on the instrument panel of the controller 100, or the warning lamp may be turned on.

On the other hand, the tank lorry control method according to an embodiment of the present invention, when any one of the three compartments (31, 32, 33) is empty, the liquid to be stored in the compartment emptied in the first step (S1) Information may be deleted (S7).

As a result, the liquid is filled in the empty compartment so that the liquid information can be newly input to the controller 100.

If the liquid information is not newly inputted, the determination cannot be made in the third step, so that the required compartment valve can be kept closed.

On the other hand, it may be further determined whether the remaining amount of the liquid in all the compartments are not empty (S8). That is, all of the liquid in the compartments in the tank 10 can be ended.

Although the embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains can understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features. will be.
