Referring to fig. 5, fig. 5 is a flowchart illustrating a method for controlling a controller in a tank truck with a pump according to an exemplary embodiment of the present application, which may be specifically performed by the controller 103 in any one of fig. 1 to 4.

As shown in fig. 5, the controller 103 is configured to perform S510 to S520, described in detail below:
S510: and calculating the relative position distance between the tank truck with the pump and the target storage tank according to the position information of the tank truck with the pump and the position information of the target storage tank.
The self position information is the position information of the tank truck with the pump. The target storage tank is a container for storing the transfer liquid, namely, the liquid in the liquid storage tank of the tank truck with the pump.
The own position information and the position information of the target tank may be coordinate information in a two-dimensional coordinate system, for example, the own position information is (1, 2), and the position information of the target tank is (2, 3).
Illustratively, the pump-equipped tank car self-location information is (x 1 ，y 1 ) The position information of the target tank is (x) 2 ，y 2 ) And calculating the relative position distance between the tank truck and the target storage tank according to the following formula:
wherein D represents the relative position distance between the tank truck and the target storage tank; (x) 1 ，y 1 ) Representing the position coordinates of the tank truck; (x) 2 ，y 2 ) Representing the location coordinates of the target tank.
S520: and if the detected relative position distance is smaller than the preset relative position distance and the liquid amount in the tank truck with the pump is reduced, controlling the tank truck with the pump to carry out parking braking.
The preset relative position distance is a preset numerical value, and the unit of the preset relative position distance is the same as the relative position distance.
If the detected relative position distance is smaller than the preset relative position distance, the characterization target storage tank is in the operation range of the tank truck, which is a precondition for the tank truck to execute the liquid unloading operation, and if the detected liquid amount in the tank truck with the pump is reduced, the characterization tank truck with the pump is in the liquid unloading operation process, so that the situation that the tank truck with the pump is displaced due to the reduction of the friction force between the tank truck with the pump and the ground is avoided, and the parking brake of the tank truck with the pump is timely controlled, so that the safety in the liquid unloading process is improved.
If the detected relative position distance is larger than the preset relative position distance, the characteristic that the target storage tank is not in the operation range, namely the linear distance between the liquid storage tank in the tank truck with the pump and the target storage tank is far, cannot meet the operation requirement of liquid transfer of the two. The alarm prompts that the target storage tank is not in the operation range, and can inform operators that the liquid storage tank and the target storage tank are not in the operation range in time, so that the operators can analyze and judge the current operation faults.
In addition, if the relative position distance is detected to be larger than the preset relative position distance, but the current moment is in a liquid unloading operation state, liquid leakage possibly occurs, or liquid in the liquid storage tank is transferred to a non-target storage tank, and the liquid unloading operation can be immediately controlled to be stopped while the alarm prompts that the target storage tank is not in an operation range.
In the embodiment, under the condition that the relative position distance between the tank truck with the pump and the target storage tank is smaller than the preset relative position distance, whether the tank truck with the pump performs parking braking is determined by detecting whether the liquid amount in the tank truck with the pump is reduced or not; if the liquid amount in the tank truck with the pump is detected to be reduced, the tank truck with the pump is rapidly controlled to carry out parking braking, so that safety accidents caused by misoperation of the tank truck with the pump are avoided.

S610: and responding to an instruction for executing the liquid unloading operation, and matching the identity information with preset identity information to obtain an identity information matching result.
The instruction for executing the liquid discharge operation is an instruction triggered by an operator, for example, the operator triggers a request to the central control platform, and the platform issues an instruction for executing the liquid discharge operation corresponding to the request to the controller 103, so that the controller 103 responds to the instruction. Wherein, each request corresponds to at least one target job, that is, one request can simultaneously correspond to a plurality of target jobs, and the target jobs can be jobs except for the liquid discharging job. The preset identity information is pre-entered information including one or more operators' identity information, such as at least one type of identity information of fingerprint, sound wave, facial image information, etc.
Illustratively, the controller 103 receives an instruction for executing the liquid unloading operation, matches the fingerprint information of the current operator acquired by the identity information acquisition device 101 with preset fingerprint information in preset identity information, and if the fingerprint information is matched, obtains a matching result representing that the identity information is successfully matched; and if the preset fingerprint information is not matched, obtaining a matching result representing that the identity information is failed to be matched.

In some embodiments, the identity authentication method may be applied in an implementation environment with a poor signal, that is, the specific processing procedure of the identity authentication may be processed by the controller 103 of the tank truck with pump 100, that is, the management platform 300 issues the identity information of the trained and qualified operator to the controller 103 of the tank truck with pump 100 in advance, the controller 103 of the tank truck with pump 100 matches the acquired identity information with the built-in authorized identity information, and determines whether to issue an instruction for executing the target job according to the matching result; if the identity information matching result represents that the identity information matching is successful, the controller 103 acquires own position information and acquires the position information of the target storage tank 102 from the target storage tank information built in the controller 103; or directly from the target tank 102, provided that the controller 103 establishes a communication connection with the target tank 102, between which data transfer may take place.
In some embodiments, to enhance the supervisory control of the pump-equipped tank truck 100 by the management platform 300, the specific process of identity authentication may be processed in the management platform 300, that is, the pump-equipped tank truck 100 uploads the collected identity information to the management platform 300, the management platform 300 performs identity information matching, and determines whether to issue an instruction for executing the target job to the controller 103 in the pump-equipped tank truck 100 according to the matching result; if the identity information matching result represents that the identity information matching is successful, the management platform 300 issues an instruction for executing the target operation to the controller 103, so that the controller 103 obtains the position information of the controller and obtains the position information of the target storage tank 102 from the management platform 300; or directly from the target tank 102, provided that the controller 103 establishes a communication connection with the target tank 102, between which data transfer may take place.
The embodiment matches the identity information acquired by the identity information acquisition device with preset identity information to perform identity verification on an operator, thereby supervising the operator. Meanwhile, in order to execute the liquid unloading operation, the condition that the relative position distance between the tank truck and the target storage tank is smaller than the preset relative position distance needs to be met, so that the liquid in the tank truck with the pump is monitored to be transferred to the target storage tank, and safety accidents caused by the transfer of the liquid to other non-standard containers are avoided.
If the monitoring is improper or the operation is improper in the process of loading/unloading the tank truck with the pump, potential safety hazards such as liquefied gas leakage and the like are extremely easy to occur, even safety accidents such as fire and explosion are caused, and the life safety and social property safety of people are seriously endangered. The existing tank truck with the pump has the problem that the safety of an operation control system is poor, and the safety accident is easily caused by improper operation of operators.
For this purpose, in another exemplary embodiment, the flowmeter records an initial reading at an initial time, and during the unloading operation, the flowmeter records a current reading of the current time passing through the flowmeter, and determines the flow of the liquid unloaded during the unloading operation at the current time according to the difference between the initial reading and the current reading of the current time passing through the flowmeter. . Referring specifically to fig. 7, fig. 7 is a flowchart illustrating another method for controlling a controller in a tank truck with a pump according to another exemplary embodiment of the present application. As shown in fig. 7, the controller 103 is further configured to perform the steps of:
S710: during the execution of the discharging operation, it is detected whether the decrease in the liquid in the tank truck with the pump is smaller than the increase in the liquid in the target tank.
Because the cost of the flowmeter is far greater than that of the liquid level meter, in the actual application scene, the tank truck with the pump is provided with the flowmeter, and the target storage tank is provided with the liquid level meter, so that the liquid reduction or increase amount can be collected and recorded. The liquid level meter records the initial liquid level in the target storage tank, and in the process of discharging operation of the tank truck with the pump, the liquid level at the current moment is recorded, and the difference value between the liquid level at the current moment and the initial liquid level is the increment of the liquid in the target storage tank. If cost is not a concern, the target tank may also be provided with a flow meter.
In the process of unloading operation which is ideally safe, free of liquid leakage and does not consider liquid volatilization, the reduction amount of the liquid in the tank truck with the pump is equal to the increase amount of the liquid in the target storage tank, namely, the liquid in the tank truck with the pump is completely transferred into the target storage tank.
S720: if the decrease amount is smaller than the increase amount, stopping executing the liquid unloading operation.
In an actual scene, due to the problems of liquid volatilization, instrument precision and the like, a certain amount of decrease and increase exist, and a certain difference exists between the decrease and increase. Therefore, in the preferred embodiment, if the decrease amount is smaller than the increase amount and the difference between the decrease amount and the increase amount is greater than the preset difference, the liquid decreased in the tank truck with pump is not completely transferred to the target storage tank, and there is a risk of leakage, and in order to avoid safety accidents, the liquid unloading operation is stopped.
According to the embodiment, whether the liquid leakage risk exists in the liquid unloading operation process or not is judged by detecting whether the reduction amount of the liquid in the tank truck with the pump is smaller than the increase amount of the liquid in the target storage tank or not, if the reduction amount of the liquid in the tank truck with the pump is smaller than the increase amount of the liquid in the target storage tank, the liquid unloading operation is immediately stopped, so that safety accidents in the liquid unloading process are avoided, and the safety of the liquid unloading operation is improved.
In order to ensure that the liquid in the liquid storage tank in the tank truck with the pump is reduced, not caused by leakage, other auxiliary detection steps are needed to determine that the liquid/gas reduction of the liquid storage tank is caused by the execution of the liquid unloading operation.
For this purpose, in a further exemplary embodiment, a pump gun sensing device is also provided in the tank truck with pump for detecting the operating state of the pump gun. The controller 103 is further configured to perform the steps of:
and if the detected relative position distance is smaller than the preset relative position distance and the operation state of the pump gun represents that the pump gun is in the operation state, executing the liquid discharging operation.
In the discharging operation, the pump gun is certainly in an operating state. If the pump gun is not in operation, but is still in operation for discharging liquid, the concrete situation may need to be analyzed due to liquid leakage or other faults.
The operation state of the pump gun can be judged according to the real-time position of the pump gun, and if the pump gun is arranged on the gun seat, the pump gun is characterized as being in an unworked state; if the pump gun is not arranged on the gun seat, the pump gun is characterized as being in an operating state. The operation states of the pump guns can be classified according to the motion trail of the pump guns, and if the motion trail of the pump guns is detected, the operation states of the pump guns are represented; and if the movement track of the pump gun is not detected, indicating that the pump gun is not in an operation state.
In this embodiment, when the relative position distance is detected to be smaller than the preset relative position distance, it needs to be determined whether the pump gun is in an operating state, and if the pump gun is detected to be in the operating state at the same time, the liquid discharging operation is executed. The safety accident in the liquid unloading operation is avoided, and the safety in the liquid unloading operation process is improved.
In another exemplary embodiment, to prevent leakage of liquid, at least one gas detector is provided around the pumped tank car for detecting the gas concentration of the combustible gas. Wherein the combustible gas is an alkane, e.g. propane (C 3 H 8 ) Propylene (C) 3 H 6 ) Butane (C) 4 H 10 ) Butene (C) 4 H 8 ) And butanedi (C) 4 H 6 ) At the same time, also contains a small amount of methane (CH) 4 ) Ethane (C) 2 H 6 ) Pentane (C) 5 H 12 ) Hydrogen sulfide (H) 2 S), etc. The controller 103 is further configured to perform the steps of:
detecting whether the gas concentration of the combustible gas is greater than a preset gas concentration;
and stopping executing the liquid unloading operation if the gas concentration of the combustible gas is detected to be larger than the preset gas concentration.
The preset gas concentration is a preset standard parameter and is used for measuring whether the concentration of the volatilized combustible gas exceeds the preset standard parameter, and if the gas concentration of the combustible gas is detected to be larger than the preset gas concentration, the condition that the concentration of the combustible gas around the tank truck with the pump exceeds the safety standard parameter is indicated, and the safety risk exists, the liquid unloading operation is stopped.
According to the embodiment, the gas detector is additionally arranged to detect whether the gas concentration of the combustible gas around the tank truck with the pump is larger than the preset gas concentration, and if the gas concentration of the combustible gas is detected to be larger than the preset gas concentration, the liquid unloading operation is immediately stopped, so that safety accidents are avoided, and the safety of the washing liquid operation is improved.
In another exemplary embodiment, the pump-equipped tank truck further comprises a liquid discharge pump for pumping liquid in the liquid storage tank of the pump-equipped tank truck to a target storage tank; and the electromagnetic valve is used for controlling the flow of the liquid pumped by the liquid discharging pump. The controller 103 is further configured to perform the steps of:

In order to increase safety during operation, in another exemplary embodiment, at least one temperature sensor is provided in the tank truck with pump for sensing the storage temperature in the tank. The controller 103 is further configured to perform the steps of:
detecting whether the storage temperature exceeds a preset temperature threshold;
and stopping executing the liquid unloading operation if the storage temperature is detected to exceed the preset temperature threshold value.
The preset temperature threshold is a preset parameter, which may be a single parameter or a parameter interval, for example, [1, 10], (1, 20), [1, 15), etc.
The liquefied petroleum oil and the like have certain requirements on the storage temperature, and safety accidents such as explosion and the like can happen after the storage temperature exceeds certain storage temperature, so that the embodiment is used for detecting whether the storage temperature of the liquid is within a safe storage temperature range or not by arranging the temperature sensor in the tank truck with the pump, and immediately stopping executing the liquid unloading operation when the storage temperature exceeds the safe storage temperature range so as to ensure the safety of the liquid unloading operation process.

The pressure sensor can collect the pressure value in the liquid storage tank, and the controller 103 obtains the collected pressure value and compares the collected pressure value with a preset pressure threshold value to determine whether to stop executing the liquid unloading operation. The controller obtains that the pressure value collected by the pressure sensor is 10Pa, the preset pressure threshold is (1 Pa,9 Pa), the pressure value at the moment exceeds the preset pressure threshold, the fact that the pressure value in the current liquid storage tank is too large is indicated, in order to avoid safety accidents, the execution of liquid unloading operation is required to be stopped, and an alarm prompts an operator to prompt the operator to carry out safety maintenance.
