Description

Technical Field

[0001] The present application relates to the technical field of drainage vehicles, and in particular to a control system and method for a drainage vehicle. Background Art

[0002] As the most commonly used type of emergency equipment, drainage trucks are often used for drainage, flood control, and waterlogging drainage. Drainage trucks are also used for irrigation of agriculture and urban greening. When the drainage truck is in use, it uses the drainage device on the drainage truck to drain the accumulated water in potholes, ditches, and rivers.

[0003] The existing drainage truck can control the engine of the drainage truck through a remote control, and the existing drainage truck includes two parts, a mother truck (box truck) and a sub-truck (mobile drainage pump station). The mother truck and the sub-truck can be controlled by different remote controllers. At the same time, the remote controller of the mother truck and the remote controller of the sub-truck can both control the speed of the engine of the mother truck. When multiple remote controllers control the engine speed of the drainage truck, if there is a conflict between the remote control signals of the multiple remote controllers, the speed of the engine of the drainage truck may fluctuate greatly, making the engine of the drainage truck prone to malfunction. Summary of the invention

[0004] In view of the above problems, the present application provides a control system and method for a drainage vehicle to solve the conflict problem of controlling the engine of a mother vehicle through multiple remote controllers in the existing drainage vehicle.

[0005] To achieve the above purpose, the inventor provides a control system for a drainage vehicle, comprising:

[0006] A remote control transmitter, the remote control transmitter at least comprising a first remote control transmitter and a second remote control transmitter, the first remote control transmitter and the second remote control transmitter are used to send a throttle control request and a remote control signal;

[0007] A remote control receiver, the remote control receiver is used to receive the throttle control request and the remote control signal sent by the first remote control transmitter and the second remote control transmitter;

[0008] The on-board programmable controller is connected to the remote control receiver. When receiving a throttle control request sent by the remote control transmitter, the on-board programmable controller is used to determine the authority of the current remote control transmitter. If the current remote control transmitter has the authority, the speed request signal is output to the engine controller according to the remote control signal sent by the current remote control transmitter.

[0009] In some embodiments, the on-board programmable controller is also used to determine whether the current control authority is empty when receiving a throttle control request sent by a remote control transmitter. If it is empty, the control authority is mapped to the current remote control transmitter. If the current control authority is not empty, it is determined whether the difference between the speed value in the remote control signal output by the current remote control transmitter and the speed value sent by the remote control transmitter with control authority is less than a preset difference. If it is less than the preset difference, the control authority is switched to the current remote control transmitter.

[0010] In some embodiments, the on-board programmable controller is also used to send a prompt signal to the current remote control transmitter when it is determined that the difference between the speed value in the remote control signal output by the current remote control transmitter and the speed value sent by the remote control transmitter with control authority is greater than a preset difference. The prompt signal is used to remind the user to adjust the speed value to an appropriate value.

[0011] In some embodiments, the first remote control transmitter and the second remote control transmitter both include a throttle request control button and a speed control knob, the throttle request control button is used to send a throttle control request, and the speed control knob is used to send a remote control signal.

[0012] In some embodiments, the throttle request control button is also used to send a throttle control request after being long pressed for a preset time.

[0013] In some embodiments, the first remote control transmitter and the second remote control transmitter both include a display screen, and the display screen is used to display the remote control transmitters that currently have authority. The first remote control transmitter and the second remote control transmitter are provided with a display screen, which can display the remote control transmitter with the current engine control authority on the display screen, so that the staff can know which remote control transmitter has the current engine control authority.

[0014] In some embodiments, the remote control receiver includes at least a first remote control receiver and a second remote control receiver, the first remote control receiver is communicatively connected to the first remote control transmitter, and the second remote control receiver is communicatively connected to the second remote control transmitter.

[0015] Another technical solution is also provided, a method for controlling a drainage vehicle, comprising the following steps:

[0016] The remote control transmitter sends a throttle control request or a remote control signal to the remote control receiver, and the remote control transmitter includes at least a first remote control transmitter and a second remote control transmitter.

[0017] When the vehicle-mounted programmable controller receives the throttle control request sent by the remote control transmitter through the remote control receiver, it determines whether the current remote control transmitter has the control authority;

[0018] If the control authority is available, a speed request signal is output to the engine controller according to the remote control signal of the current remote control transmitter.

[0019] In some embodiments, the step of "determining whether the current remote control transmitter has control authority" specifically includes the following steps:

[0020] When receiving a throttle control request from a remote control transmitter, determine whether the current control authority is empty;

[0021] If it is empty, the control authority will be mapped to the current remote control transmitter;

[0022] If it is not empty, determine whether the difference between the speed value in the remote control signal output by the current remote control transmitter and the speed value sent by the remote control transmitter with control authority is less than the preset difference;

[0023] If it is less than the preset difference, the control authority will be switched to the current remote control transmitter.

[0024] In some embodiments, the step of "determining whether the difference between the rotation speed value in the remote control signal output by the current remote control transmitter and the rotation speed value sent by the remote control transmitter with control authority is less than a preset difference" further includes the following steps:

[0025] If it is greater than a preset difference, a prompt signal is sent to the current remote control transmitter, and the prompt signal is used to remind the rotation speed value to be adjusted to a suitable value.

[0026] Different from the prior art, the above technical solution, when multiple remote control transmitters control the speed of the drainage truck engine, when the remote control receiver receives the signal sent by the remote control transmitter, it sends the received signal to the on-board programmable controller. When the on-board programmable controller confirms that the received signal is a throttle control signal, it determines whether the remote control receiver currently sending the signal has the authority. If it has the authority, it switches the control authority to the current remote control transmitter, and outputs the speed request signal to the engine controller according to the remote control signal of the current remote control transmitter, thereby controlling the engine speed of the drainage truck. The drainage truck engine is controlled according to the different authorities of the remote control transmitter, avoiding conflicts when different remote control transmitters control the engine of the mother vehicle.

[0050] See also Figure 1 , this embodiment provides a control system for a drainage vehicle, including:

[0051] A remote control transmitter, the remote control transmitter at least comprising a first remote control transmitter 111 and a second remote control transmitter 112, wherein the first remote control transmitter 111 and the second remote control transmitter 112 are used to send a throttle control request and a remote control signal;

[0052] A remote control receiver 121, the remote control receiver 121 is used to receive the throttle control request and the remote control signal sent by the first remote control transmitter 111 and the second remote control transmitter 112;

[0053] The on-board programmable controller 122 is connected to the remote control receiver 121. When receiving a throttle control request sent by the remote control transmitter, the on-board programmable controller 122 is used to determine the authority of the current remote control transmitter. If the current remote control transmitter has the authority, the speed request signal is output to the engine controller 130 according to the remote control signal sent by the current remote control transmitter.

[0054] When multiple remote control transmitters control the speed of the drainage vehicle engine, when the remote control receiver 121 receives the signal sent by the remote control transmitter, it sends the received signal to the on-board programmable controller 122. When the on-board programmable controller 122 confirms that the received signal is a throttle control signal, it determines whether the remote control receiver 121 currently sending the signal has the authority. If it has the authority, it switches the control authority to the current remote control transmitter, and outputs the speed request signal to the engine controller 130 according to the remote control signal of the current remote control transmitter, thereby controlling the engine speed of the drainage vehicle. The drainage vehicle engine is controlled according to the different authorities of the remote control transmitter to avoid conflicts when different remote control transmitters control the mother vehicle engine.

[0055] The remote control transmitter is not only used to transmit signals, but also can receive signals sent by the remote control receiver 121. The remote control receiver 121 is not only used to receive signals, but also can be used to send signals to the remote control transmitter. The remote control transmitter and the remote control receiver 121 are connected in communication, and the remote control transmitter and the remote control receiver 121 can communicate wirelessly through Bluetooth communication, infrared communication, millimeter wave communication and other communication methods.

[0056] In some embodiments, the on-board programmable controller 122 is also used to determine whether the current control authority is empty when receiving a throttle control request sent by a remote control transmitter. If it is empty, the control authority is mapped to the current remote control transmitter. If the current control authority is not empty, it is determined whether the difference between the speed value in the remote control signal output by the current remote control transmitter and the speed value sent by the remote control transmitter with control authority is less than a preset difference. If it is less than the preset difference, the control authority is switched to the current remote control transmitter. When the on-board programmable controller 122 receives a throttle control request sent by a remote control transmitter, it first determines whether the current control authority is empty, that is, whether there is a remote control transmitter controlling the speed of the drainage vehicle's engine. If not, the control authority is mapped to the remote control transmitter that currently sends the throttle control request, and the engine speed is controlled according to the remote control signal of the remote control transmitter. If the current control authority is not empty, that is, the current control authority is in other remote control transmitters, then it is determined whether the difference between the speed value in the remote control signal of the remote control transmitter that currently sends the throttle control request and the speed value in the remote control signal of the remote control transmitter that currently has control authority is less than a preset difference. If it is less than the preset difference, the control authority is switched to the remote control transmitter that sends the throttle control request, and the drainage vehicle's engine is controlled according to the remote control signal sent by the remote control transmitter.

[0057] In some embodiments, the vehicle-mounted programmable controller 122 is also used to send a prompt signal to the current remote control transmitter when it is determined that the difference between the speed value in the remote control signal output by the current remote control transmitter and the speed value sent by the remote control transmitter with control authority is greater than a preset difference, and the prompt signal is used to remind the speed value to be adjusted to an appropriate value. When the vehicle-mounted programmable controller 122 determines that the difference between the speed value in the remote control signal output by the remote control transmitter that currently sends the throttle control request and the speed value sent by the remote control transmitter with control authority is greater than a preset difference, a prompt signal is sent to the current remote control transmitter to remind the remote control transmitter to send an appropriate speed value, so that the remote control transmitter with a speed adjustment span that is too large cannot obtain authority.

[0058] See also Figure 2-4 In some embodiments, the first remote control transmitter 111 and the second remote control transmitter 112 both include a throttle request control button 113 and a speed control knob 114. The throttle request control button 113 is used to send a throttle control request, and the speed control knob 114 is used to send a remote control signal. The throttle control request can be sent through the throttle request control button 113, and the remote control signal can be sent through the speed control knob 114. In other embodiments, different levels of speed buttons can also be set, and different remote control signals can be output according to different speed buttons.

[0059] In some embodiments, the throttle request control button 113 is also used to send a throttle control request after being pressed for a preset time. In order to avoid the throttle request control button 113 being pressed by mistake and causing a mistaken request for throttle control authority, the remote control transmitter will only send a throttle control request after the throttle request control button 113 is pressed for a preset time. In order to further avoid the throttle request control button 113 being pressed by mistake, when the throttle request control button 113 is pressed for a long time, it is determined whether it is released within a second preset time. If it is released, the throttle control request is sent, and if it exceeds the second preset time, the throttle control request is not sent, wherein the second preset time is longer than the first preset time.

[0060] See also Figure 2-4 In some embodiments, the first remote control transmitter 111 and the second remote control transmitter 112 both include a display screen 115, and the display screen 115 is used to display the remote control transmitters that currently have authority. By setting the display screen 115 on the first remote control transmitter 111 and the second remote control transmitter 112, and displaying the remote control transmitters that currently have authority on the display screen 115, the staff can know the remote control transmitter that currently has the control authority of the throttle.

[0061] See also Figure 3-4In some embodiments, the remote control receiver 121 includes at least a first remote control receiver 1211 and a second remote control receiver 1212, wherein the first remote control receiver 1211 is in communication connection with the first remote control transmitter 111, and the second remote control receiver 1212 is in communication connection with the second remote control transmitter 112. By establishing a communication connection between the first remote control receiver 1211 and the first remote control transmitter 111, and by establishing a communication connection between the second remote control receiver 1212 and the second remote control transmitter 112, it is possible to more accurately determine which remote control transmitter sends the throttle control request and the remote control signal.

[0062] See also Figure 4 In other embodiments, the remote control transmitter further includes a third remote control receiver 1213 , the remote control receiver 121 includes a third remote control transmitter 116 , and the third remote control transmitter 116 is communicatively connected to the third remote control receiver 1213 .

[0063] In other embodiments, a control system for a drainage vehicle, the remote control transmitter includes a first remote control transmitter 111, a second remote control transmitter 112 and a third remote control transmitter 116, the remote control receiver includes a first remote control receiver 1211, a second remote control receiver 1212 and a third remote control receiver 1213, the first remote control receiver 1211 is communicatively connected to the first remote control transmitter 111, the second remote control receiver 1212 is communicatively connected to the second remote control transmitter 112, and the third remote control receiver 1213 is communicatively connected to the third remote control transmitter 116; the first remote control transmitter 111 sends a throttle control request signal A1 and a remote control signal B1 to the on-board programmable controller 122, and the first remote control transmitter 111 receives the current speed control signal sent by the first remote control receiver The second remote control transmitter 112 sends the throttle control request signal A2 and the remote control signal B2 to the on-board programmable controller 122, and the second remote control transmitter 112 receives the current speed control right owner C and the current engine speed value D, as well as the switching prompt E sent by the second remote control receiver; the third remote control transmitter 116 sends the throttle control request signal A3 and the remote control signal B3 to the on-board programmable controller 122, and the third remote control transmitter 116 receives the current speed control right owner C and the current engine speed value D, as well as the switching prompt E sent by the third remote control receiver; wherein the switching prompt E includes two states E1 and E2; E1 indicates that the control right is successfully switched; E2 indicates that the switch fails, please adjust the speed. Please refer to Figure 5, when the current engine control right is empty, when a throttle control request is received, determine which remote control transmitter sent the throttle control request. First, determine whether the received throttle control request is A1 (i.e., whether A1 is true). If it is A1, it means that it is sent by the first remote control transmitter. Then determine whether D-B1 is less than the preset difference. If it is less than the preset difference, adjust the current engine speed value to B1, and map the authority to the first remote control transmitter, and switch the switching prompt E to E1. If it is greater than the preset difference, switch the switching prompt to E2. If the currently received throttle control is not A1, determine whether it is A2. If it is A2, it means that it is sent by the second remote control transmitter. Then determine whether D-B2 is less than the preset difference. If it is less than the preset difference, adjust the current engine speed value to B2, map the authority to the second remote control transmitter, and switch the switch prompt E to E1. If it is greater than the preset difference, switch the switch prompt to E2. If the throttle control currently received is not A2, determine whether it is A3. If it is A3, it means that it is sent by the third remote control transmitter. Then determine whether D-B3 is less than the preset difference. If it is less than the preset difference, adjust the current engine speed value to B3, map the authority to the third remote control transmitter, and switch the switch prompt E to E1. If it is greater than the preset difference, switch the switch prompt to E2. Please refer to Figure 6 In another embodiment, a method for controlling a drainage vehicle includes the following steps:

[0064] Step S610: The remote control transmitter sends a throttle control request or a remote control signal to the remote control receiver, wherein the remote control transmitter includes at least a first remote control transmitter and a second remote control transmitter.

[0065] Step S620: When the vehicle-mounted programmable controller receives the throttle control request sent by the remote control transmitter through the remote control receiver, it determines whether the current remote control transmitter has control authority;

[0066] If the control authority is available, then step S630: outputting a speed request signal to the engine controller according to the remote control signal of the current remote control transmitter;

[0067] If the authority is not possessed, step S640: do not respond to the remote control signal of the current remote control transmitter.

[0068] When multiple remote control transmitters control the engine speed of the drainage truck, when the remote control receiver receives the signal sent by the remote control transmitter, it sends the received signal to the on-board programmable controller. When the on-board programmable controller confirms that the received signal is a throttle control signal, it determines whether the remote control receiver currently sending the signal has the authority. If it has the authority, it switches the control authority to the current remote control transmitter, and outputs the speed request signal to the engine controller according to the remote control signal of the current remote control transmitter, thereby controlling the engine speed of the drainage truck. The drainage truck's engine is controlled according to the different authorities of the remote control transmitter to avoid conflicts when different remote control transmitters control the engine of the mother vehicle.

[0069] In some embodiments, the step of "determining whether the current remote control transmitter has control authority" specifically includes the following steps:

[0070] When receiving a throttle control request from a remote control transmitter, determine whether the current control authority is empty;

[0071] If it is empty, the control authority will be mapped to the current remote control transmitter;

[0072] If it is not empty, determine whether the difference between the speed value in the remote control signal output by the current remote control transmitter and the speed value sent by the remote control transmitter with control authority is less than the preset difference;

[0073] If it is less than the preset difference, the control authority will be switched to the current remote control transmitter.

[0074] When the on-board programmable controller receives a throttle control request sent by a remote control transmitter, it first determines whether the current control authority is empty, that is, whether there is a remote control transmitter to control the speed of the drainage vehicle's engine. If not, the control authority is mapped to the remote control transmitter that currently sends the throttle control request, and the engine speed is controlled according to the remote control signal of the remote control transmitter. If the current control authority is not empty, that is, the current control authority is in other remote control transmitters, then it is determined whether the difference between the speed value in the remote control signal of the remote control transmitter that currently sends the throttle control request and the speed value in the remote control signal of the remote control transmitter that currently has control authority is less than a preset difference. If it is less than the preset difference, the control authority is switched to the remote control transmitter that sends the throttle control request, and the drainage vehicle's engine is controlled according to the remote control signal sent by the remote control transmitter.

[0075] In some embodiments, the step of "determining whether the difference between the rotation speed value in the remote control signal output by the current remote control transmitter and the rotation speed value sent by the remote control transmitter with control authority is less than a preset difference" further includes the following steps:

[0076] If it is greater than a preset difference, a prompt signal is sent to the current remote control transmitter, and the prompt signal is used to remind the rotation speed value to be adjusted to a suitable value.

[0077] When the on-board programmable controller determines that the difference between the speed value in the remote control signal output by the remote control transmitter that currently sends the throttle control request and the speed value sent by the remote control transmitter with control authority is greater than the preset difference, it sends a prompt signal to the current remote control transmitter to remind the remote control transmitter to send a suitable speed value, so that the remote control transmitter with a speed adjustment span that is too large cannot obtain authority.

[0078] In some embodiments, the throttle request control button of the remote control transmitter sends a throttle control request after being long pressed for a preset time. In order to avoid the throttle request control button being pressed by mistake and causing an incorrect request for throttle control authority, the remote control transmitter will send a throttle control request only after the throttle request control button is long pressed for a preset time. In order to further avoid the throttle request control button being pressed by mistake, when the throttle request control button is long pressed, it is determined whether it is released within a second preset time. If it is released, the throttle control request is sent, and if it exceeds the second preset time, the throttle control request is not sent, wherein the second preset time is longer than the first preset time.

[0079] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.

The control system of the drainage vehicle according to claim 1, characterized in that: The remote control receiver includes at least a first remote control receiver and a second remote control receiver, the first remote control receiver is communicatively connected to the first remote control transmitter, and the second remote control receiver is communicatively connected to the second remote control transmitter.

7. A method for controlling a drainage vehicle, characterized in that: The following steps are involved: The remote control transmitter sends a throttle control request or a remote control signal to the remote control receiver, wherein the remote control transmitter comprises at least a first remote control transmitter and a second remote control transmitter; When the on-board programmable controller receives the throttle control request sent by the remote control transmitter through the remote control receiver, it determines whether the current remote control transmitter has the control authority; If the control authority is available, a speed request signal is output to the engine controller according to the remote control signal of the current remote control transmitter; The step of "determining whether the current remote control transmitter has control authority" specifically includes the following steps: When receiving a throttle control request from a remote control transmitter, determine whether the current control authority is empty; If it is empty, the control authority will be mapped to the current remote control transmitter; If it is not empty, determine whether the difference between the speed value in the remote control signal output by the current remote control transmitter and the speed value sent by the remote control transmitter with control authority is less than the preset difference; If it is less than the preset difference, the control authority will be switched to the current remote control transmitter.

8. The control method of the drainage vehicle according to claim 7, characterized in that: The step of "determining whether the difference between the rotation speed value in the remote control signal output by the current remote control transmitter and the rotation speed value sent by the remote control transmitter with control authority is less than the preset difference" also includes the following steps: If it is greater than a preset difference, a prompt signal is sent to the current remote control transmitter, and the prompt signal is used to remind the rotation speed value to be adjusted to a suitable value.
