Description

Technical Field

[0001] The present invention relates to the technical field of pump truck control, and in particular to a pump truck gear remote starting control system and method. Background Art

[0002] The current pump truck engine can only be started when the vehicle is in neutral gear. Some pump trucks are in gear-operated power-taking state during loading operations. Pump truck drivers usually work outside the cab. When taking a break between operations, the driver will remotely shut down the vehicle. If they continue to work, the vehicle is still in gear and cannot be remotely started in gear. The driver needs to return to the cab from outside the vehicle to return the vehicle gear to neutral, start the engine, shift gears to take power, and then return to the cab to perform loading operations. Since pump trucks have long operating hours and long waiting times during breaks, this operation is too complicated. For pump trucks, remote starting with gear can greatly improve the convenience of operation.

[0003] The existing gear start scheme uses the method of short-circuiting the neutral signal to achieve gear remote start, which is not suitable for pump trucks. The pump truck's upper body controller will determine whether to switch the upper body operation mode back to the normal driving mode based on the neutral signal, that is, exit the power take-off function. If a short-circuited neutral signal is received, the actual vehicle is not in the neutral state. If the driver mistakenly switches to the normal driving mode at this time, there is a risk of gear knocking in the upper body transfer case. Only by shorting the neutral signal and other methods to achieve gear start, it cannot be guaranteed that the vehicle is in the power take-off state, that is, the power input of the whole vehicle has been switched to the upper body, and there is a safety risk of the vehicle running out.

[0004] Therefore, it is urgent to propose a control system and method for remote starting of a pump truck with gear, so as to solve the technical problem that the prior art only realizes starting with gear by short-circuiting the neutral signal, and cannot ensure that the vehicle is in a power-taking state, that is, the power input of the whole vehicle has been switched to the upper body, and the vehicle may have the safety risk of running out. Summary of the invention

[0005] In view of this, it is necessary to provide a control system and method for remote starting of a pump truck with gear, so as to solve the technical problem in the prior art that starting with gear is achieved only by short-circuiting the neutral signal, etc., and it cannot be ensured that the vehicle is in a power-taking state, that is, the power input of the whole vehicle has been switched to the upper body, and there is a safety risk that the vehicle may run out.

[0006] In order to solve the above problems, the present invention provides a pump truck gear remote start control system, comprising: A starting module, used to output the power of the pump truck to the loading module when the pump truck starts loading operation; The upper loading module is used to start the upper loading operation mode of the pump truck when receiving the power; The remote control module is used to send the remote start signal to the upper installation module after receiving the remote start signal, so that the upper installation module can judge the gear position and engine status of the pump truck when starting the upper installation operation mode, and perform remote start control with gear according to the remote start signal when the judgment result is not neutral.

[0007] In one possible implementation, the starting module includes a power take-off switch and a transfer case. The starting module is also used to start the transfer case and start taking power when the power take-off switch is pressed. After the transfer case completes taking power, the power of the pump truck is output to the upper module.

[0008] In a possible implementation, the transfer case is installed between the transmission shaft and the drive axle.

[0009] In a possible implementation, the starting module is also used to determine whether the transfer case is in a hooked state based on a power take-off feedback switch signal of the transfer case. If so, the transfer case is controlled to start taking power and the power take-off feedback switch signal is sent to the upper module.

[0010] In one possible implementation, the upper loading module includes an upper loading controller; the upper loading controller is used to determine whether the power take-off switch of the starting module is pressed, and whether the power take-off feedback switch signal is activated. If so, it is determined that the pump truck meets the conditions for starting the upper loading operation mode, and the upper loading operation mode is started.

[0011] In a possible implementation, the upper installation module further includes a BBM controller, and the BBM controller is used to receive an upper installation operation mode signal sent by the upper installation controller after starting the upper installation operation mode, and broadcast the upper installation operation mode signal in the form of a message.

[0012] In a possible implementation, the upper installation module further includes an engine control system controller, and the engine control system controller is configured to not respond to a throttle signal in the cab of the pump truck after receiving the upper installation operation mode signal broadcast by the BBM controller.

[0013] In a possible implementation, the bodywork controller is further configured to transmit the remote start signal sent by the remote control module to the BBM controller via a hard line after receiving the remote start signal; The BBM controller is used to broadcast the remote start signal on the bus in the form of a message; The engine control system controller is used to perform gear-shift remote start control according to the remote start signal after receiving the message instruction of the remote start signal and when the pump truck and the engine meet a first preset condition.

[0014] In a possible implementation, the first preset condition includes that the pump truck enters the upper loading operation mode, the pump truck is in a non-reverse gear state, the engine has no faults, the engine is in a shutdown state, and the engine control system receives a message signal of the remote start signal.

[0015] On the other hand, the present invention also provides a pump truck gear remote start control method, comprising: When the pump truck starts loading operation, the power of the pump truck is obtained; When the power is received, the loading operation mode of the pump truck is started; After receiving the remote start signal, the gear position and engine status of the pump truck are judged to obtain a judgment result; When the judgment result is that the gear is not in neutral, remote start control with gear engaged is performed according to the remote start signal.

[0016] The beneficial effects of the present invention are as follows: the starting module is used to output the power of the pump truck to the loading module when the pump truck starts the loading operation; the loading module is used to start the loading operation mode of the pump truck when receiving the power; the remote control module is used to send the remote starting signal to the loading module after receiving the remote starting signal, so that the loading module can judge the gear position and engine status of the pump truck when starting the loading operation mode, and perform remote starting control with gear according to the remote starting signal when the judgment result is a non-neutral state. The present invention outputs the power of the pump truck to the loading module to start the loading operation mode, ensuring that the pump truck is in a power-taking state. After the pump truck starts the loading operation mode, not only the non-neutral state of the gear position of the pump truck is judged, but also the engine status is judged, thereby realizing multi-faceted control of remote starting with gear, thereby ensuring the safety of the pump truck.

DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0019] A pump truck, also known as a concrete pump truck, is a machine that uses pressure to continuously transport concrete along a pipeline. It is mainly composed of a pump body and a delivery pipe. The pump body is installed on the chassis of the car and is equipped with a retractable or tortuous placing boom. The hydraulic pump pushes the piston to drive the concrete pump to work and transport the concrete to a certain height and distance. Concrete pump trucks are mainly used for the transportation of concrete in construction. They can efficiently transport concrete to high-rise buildings or other difficult-to-access construction sites. In addition, pump trucks can also be equipped with placing booms to achieve precise laying of concrete.

[0020] like Figure 1 As shown, a specific embodiment of the present invention discloses a pump truck gear remote start control system 100, comprising: The starting module 101 is used to output the power of the pump truck to the loading module 102 when the pump truck starts loading operation; The upper loading module 102 is used to start the upper loading operation mode of the pump truck when receiving power; The remote control module 103 is used to send the remote start signal to the upper installation module after receiving the remote start signal, so that the upper installation module can judge the gear position and engine status of the pump truck when starting the upper installation operation mode, and perform remote start control with gear according to the remote start signal when the judgment result is not neutral.

[0021] It should be noted that the conditions for the pump truck to start loading operations include the following aspects: Pump truck in place: The pump truck should be parked in a flat and solid place with no obstacles around and no high-voltage transmission lines above. Pump trucks must not be parked on slopes. Outrigger extension: After the pump truck is in place, the outriggers should be propped up and the fuselage should be kept level and stable. Inspection items qualified: The following items need to be checked before operation: Fuel, lubricating oil, hydraulic oil, water tank are adequately filled, tire pressure meets regulations, and lighting and signal indicators are complete and in good condition. The hydraulic system works normally, there is no leakage in the pipeline, and the cleaning water pump and equipment are complete and in good condition. There is no debris in the mixing bucket, and the protective grid on the hopper is intact and covered tightly. The conveying pipeline is firmly connected and well sealed. The basic operation process of the pump truck includes the following steps: Chassis power take-off operation: The driving pumping switch is completed in the cab. Before the power take-off operation, the neutral gear is put on and the handbrake is pulled, and the power take-off switch is pressed. After the power take-off is completed, the corresponding gear is engaged, generally the 1:1 speed ratio gear. ‌Deploy the outriggers and level them: Deploy the outriggers and level them in the near control state. When leveling, observe the level gauge next to the outrigger multi-way valve or the level data on the display screen. ‌Pumping concrete‌: Lubricate the pipeline with a small amount of mortar before pumping. When pouring pumped concrete on site, no one should stand within 1 meter on both sides of the conduit to prevent the conduit from swinging and injuring people. ‌Closing work‌: First retract the boom by remote control and then switch to near control to retract the outriggers. ‌Basic structure and function of the pump truck‌: ‌Structural composition‌: The pump truck consists of five parts: boom, pumping, hydraulic, support, and electric control. The pump body is installed on the chassis of the car and is equipped with a retractable or flexing placing boom. ‌Function‌: Use pressure to continuously transport concrete along the pipeline, which is suitable for various construction sites. Through the above steps and conditions, the safety and smooth progress of the pump truck loading operation can be ensured.

[0022] In a specific embodiment of the present invention, the embodiment of the present invention may include a starting module 101, a loading module 102 and a remote control module 103. The starting module 101 can be used to prepare for loading operations on the pump truck. When the pump truck is ready to start loading operations, the pump truck stays still and outputs power to the loading module 102. When the loading module 102 receives power, it indicates that the conditions for loading are met, and the loading operation mode of the pump truck can be started. Then, the pump truck can be controlled by the remote control module 103. When a remote start signal is received, the remote start signal can be sent to the loading module 102. The loading module 102 can judge the gear position and engine status of the pump truck to obtain a judgment result, and when the judgment result is not neutral, the pump truck is remotely started with gear according to the remote start signal.

[0023] Compared with the prior art, the starting module provided in this embodiment is used to output the power of the pump truck to the loading module when the pump truck starts the loading operation; the loading module is used to start the loading operation mode of the pump truck when receiving the power; the remote control module is used to send the remote starting signal to the loading module after receiving the remote starting signal, so that the loading module can judge the gear position and engine status of the pump truck when starting the loading operation mode, and perform remote starting control with gear according to the remote starting signal when the judgment result is non-neutral. The present invention outputs the power of the pump truck to the loading module to start the loading operation mode, ensuring that the pump truck is in a power-taking state. After the pump truck starts the loading operation mode, not only the non-neutral state of the gear of the pump truck is judged, but also the engine state is judged, thereby realizing multi-faceted control of remote starting with gear, thereby ensuring the safety of the pump truck.

[0024] In some embodiments of the present invention, Figure 2 As shown, the start module 101 may include a power take-off switch 1011 and a transfer case 1012. When the driver needs to perform loading operations, he will press the power take-off switch 1011 in the cab. The start module 101 may also be used to start the transfer case 1012 when the power take-off switch 1011 is pressed to achieve power take-off of the transfer case 1012. After the power take-off of the transfer case 1012 is completed, the power of the pump truck is output to the loading module 102. The transfer case 1012 can be installed between the transmission shaft and the drive axle, and the chassis drive axle will not rotate.

[0025] In some embodiments of the present invention, there is a power take-off feedback switch signal on the transfer case 1012, and this switch can feedback whether the transfer case 1012 is in the engaged state, so the start module 101 can also be used to determine whether the transfer case 1012 is in the engaged state according to the power take-off feedback switch signal of the transfer case 1012. If so, it means that the power take-off feedback switch signal is activated, and then the transfer case 1012 can be controlled to start taking power, and the power take-off feedback switch signal is sent to the upper module 102. This power take-off feedback switch signal is also connected to the upper controller.

[0026] In some embodiments of the present invention, the upper loading module 102 includes an upper loading controller 1021; the upper loading controller 1021 is used to determine whether the power take-off switch 1011 of the starting module 101 is pressed, and to determine whether the power take-off feedback switch signal is activated. If so, it means that the pump truck meets the conditions for starting the upper loading operation mode, and starts the upper loading operation mode, and feeds back the upper loading operation mode signal to the BBM controller 1022 through a hard line.

[0027] In a specific embodiment of the present invention, a PTO activation switch, a power take-off switch, and a driving mode switching switch are provided in the cab. All three switches are connected to the upper body controller; the premise for entering the upper body operation mode is to judge: 1. The transfer case power take-off feedback switch is activated, the power take-off is engaged, and the power output is switched to the upper body / 2. The PTO activation switch is pressed, that is, the driver is ready to start the upper body operation at this time / 3. The power take-off switch is pressed. The upper body controller makes the above judgments and then sends out the upper body operation mode signal.

[0028] In some embodiments of the present invention, the upper installation module 102 further includes a BBM controller 1022, which is used to receive an upper installation operation mode signal sent after the upper installation controller 1021 starts a hard-line signal of the upper installation operation mode, and broadcast the upper installation operation mode signal via a message.

[0029] In some embodiments of the present invention, the upper installation module 102 also includes an engine control system controller 1023, which is used to not respond to the throttle signal in the cab of the pump truck after receiving the hard-wire signal of the upper installation operation mode signal broadcast by the BBM controller 1022.

[0030] In some embodiments of the present invention, the upper-mounted controller 1021 is further configured to transmit the message command of the remote start signal that can be sent by the remote control module 103 via the remote controller 1031 to the BBM controller 1022 via a hard line; The BBM controller 1022 is used to broadcast the remote start signal on the bus in the form of a message; The engine control system controller 1023 can be used to perform remote start control with gear according to the remote start signal after receiving the message instruction of the remote start signal sent by the BBM controller 1022 by broadcasting, when the pump truck and the engine meet the first preset condition. Among them, the first preset condition may include the pump truck entering the upper installation operation mode, the pump truck is in a non-reverse gear state, the engine has no fault, the engine is in a shutdown state, and the engine control system receives a message signal of the remote start signal. In the upper installation operation mode, the pump truck can be remotely started with gear when it is in a non-neutral state and the transfer case is in a power take-off state. In the non-upper installation operation mode, the engine start still needs to determine the neutral gear.

[0031] In a specific embodiment, the control device and system suitable for pump truck operation and remote starting with gear include a PTO activation switch, a power take-off switch, a driving mode switching switch, a body controller, a transfer case power take-off feedback switch, a BBM controller, an engine control system controller and related accessories.

[0032] PTO activation switch: The switch is arranged in the cab. When the driver presses the switch, it indicates that the vehicle is ready to enter the upper load operation mode. This switch is hardwired to the upper load controller. When the upper load controller determines that the transfer case is currently in the power take-off state, the PTO activation switch signal is sent to the BBM controller through a hardwire signal.

[0033] Power take-off switch: The switch is arranged in the cab. When the superstructure is ready for operation, the driver must first press the power take-off switch, that is, engage the transfer case to take power and switch the vehicle's power output to the superstructure.

[0034] Driving mode switch: This switch is arranged in the cab. When the vehicle completes the loading operation, press this switch to indicate that the vehicle exits the loading operation mode and the power take-off state and can enter the normal driving state.

[0035] Transfer case power take-off feedback switch: This switch is located on the transfer case and can provide feedback on whether the transfer case is actually engaged. It is hardwired to the bodywork controller. Switch activation proves that the vehicle power input has been switched to the bodywork and the vehicle meets the conditions for bodywork operations.

[0036] Bodywork controller: responsible for controlling various functions of bodywork operation, etc. Determine the status of the transfer case power take-off feedback switch. When the transfer case power take-off switch is closed and the transfer case power take-off feedback switch is activated, it will respond to the PTO activation switch signal and output the PTO activation hard-line signal to the chassis controller.

[0037] Chassis controller: The OEM's own controller is used to communicate with the modified vehicle's body control system and control the body's special functions, forward signals, and other functions. The hardwire is connected to the PTO activation signal, remote start, and remote shutdown signal, and the status of these signals is broadcast on the bus through messages. When the hardwire signal of PTO activation is received, the body operation mode signal is broadcast, and when the hardwire signal of remote start is received, the remote start request signal is broadcast through the bus.

[0038] Engine control system controller: determines whether the current mode is the upper body operation mode through the bus signal broadcast by BBM. If the vehicle is in the upper body operation mode, it will not respond to the throttle request in the cab; when receiving the remote start request bus signal, the vehicle is in a non-neutral state, and responds to the start request if all the prerequisites are met, and drives the starter relay to complete the start of the starter.

[0039] The embodiment of the present invention can realize the remote start of the pump truck with gear on without short-circuiting the neutral signal and ensuring that the power output has been transmitted to the upper body, without affecting other functions and the accuracy of the vehicle signal and ensuring the safety of the remote start with gear on. After the pump truck enters the upper body operation mode, the engine does not respond to the accelerator in the cab, avoiding the risk of damage to the upper body due to accidental stepping on the accelerator.

[0040] In order to better implement the pump truck gear remote start control system in the embodiment of the present invention, based on the pump truck gear remote start control system, the embodiment of the present invention also provides a pump truck gear remote start control method, such as Figure 3 As shown, the pump truck gear remote start control method 300 includes: S301, when the pump truck starts loading operation, obtaining power of the pump truck; S302, when power is received, starting the loading operation mode of the pump truck; S303, after receiving the remote start signal, judging the gear position and engine status of the pump truck to obtain a judgment result; S304: When the result of the judgment is that the gear is not in neutral, remote start control with gear engaged is performed according to the remote start signal.
