[0053] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.
[0054] It should be noted that the terms "first," "second," and so on, in the specification, claims, and drawings of the present invention are used to distinguish different objects, and are not intended to limit a specific order. The following embodiments of the present invention can be implemented independently or in combination with each other, and the present invention does not impose specific limitations on this.
[0055] Figure 1This is a structural block diagram of a hydraulic lock control system for a diversion cabin provided by an embodiment of the present invention, see Figure 1 The hydraulic lock control system for the deflector cabin includes a vehicle body control module 10, a hydraulic lock module 20, and a switch module 30. The vehicle body control module 10 includes a processing device 110 and a sensor information acquisition device 120. The hydraulic lock module 20 includes multiple lifting switches 210. The sensor information acquisition device 120 is connected to the switch module 30 and the lifting switch 210, respectively, and is used to collect gear information of the switch module 30 and status information of the lifting switch 210. The processing device 110 is connected to the sensor information acquisition device 120 to obtain the speed information of the entire vehicle, determine the driving status of the entire vehicle based on the gear information and speed information, and control the hydraulic lock module 20 to unlock or send an alarm message based on the driving status and status information.
[0056] Specifically, the vehicle body control module 10 includes a processing device 110 and a sensor information acquisition device 120. The processing device 110 may be a central processing unit (CPU). The sensor information acquisition device 120 is in communication with the switch module 30 and is configured to collect gear position information from the switch module 30. The switch module 30 may be the vehicle's starting switch, and the gear position information from the switch module 30 includes the vehicle's four gear positions: LOCK, ACC, ON, and START. Specifically, the LOCK position is the lock position, which is where the vehicle key is inserted and removed. When the switch module 30 is in the LOCK position, all circuits in the vehicle are completely shut down, locking the steering wheel, except for the anti-theft system and the interior lights. The ACC position is the accessory power position. When the switch module 30 is in the ACC position, the accessory circuits are connected, allowing devices such as the radio to operate normally. The ON position is the on position. When the switch module 30 is in the ON position, the vehicle circuits are connected, and the system performs necessary preparations and self-tests for starting the engine. When the vehicle is in motion, the switch module 30 remains in the ON position. The START position is the starting position. When the switch module 30 is in the START position, the starter circuit is connected, driving the engine and starting it. The switch module 30 automatically returns to the ON position when the key is released.
[0057] In addition, there are other modules in the system of the whole vehicle that can collect the speed information of the whole vehicle. The processing device 110 is communicated with the module to obtain the speed information of the whole vehicle in real time. The processing device 110 is communicated with the sensor information acquisition device 120. The sensor information acquisition device 120 transmits the collected gear information of the switch module 30 to the processing device 110. The processing device 110 determines the driving status of the whole vehicle based on the acquired speed information of the whole vehicle and the gear information of the switch module 30. For example, when the acquired gear information of the switch module 30 is the on gear, and the speed information of the whole vehicle is 0 at this time, it is judged that the whole vehicle is in the parking state; and when the acquired gear information of the switch module 30 is the on gear, and the speed information of the whole vehicle is greater than 0 at this time, it is judged that the whole vehicle is in the driving state.
[0058] The hydraulic lock module 20 is used to lock the deflector cabin, ensuring that the deflector cabin is fixed to the vehicle, thereby reducing the wind resistance of the vehicle during driving. The hydraulic lock module 20 includes multiple lifting switches 210. The multiple lifting switches 210 can be understood as sensors used to determine whether the hydraulic lock module 20 has failed. Exemplarily, the status information of the lifting switches 210 includes a closed state and an open state. When the status information of the multiple lifting switches 210 is all closed, the hydraulic lock module 20 is not faulty, the deflector cabin is correctly positioned, and there is no risk of the deflector cabin tipping over. When the status information of at least one of the multiple lifting switches 210 is open, it indicates that the hydraulic lock module 20 has failed and the risk of the deflector cabin tipping over is high. The sensor information acquisition device 120 is also communicatively connected to the multiple lifting switches 210 to collect the status information of the multiple lifting switches 210 and transmit the collected status information of the multiple lifting switches 210 to the processing device 110. Furthermore, when it is determined that the driving state of the entire vehicle is the driving state, the processing device 110 determines whether the hydraulic lock module 20 is faulty based on the status information of the multiple lifting switches 210, and sends an alarm message when the hydraulic lock module 20 fails for the safety officer to monitor or repair, which can avoid the driving risk caused by the tipping of the diversion cabin due to the failure of the hydraulic lock module 20, thereby improving the driving safety; or, when it is determined that the driving state of the entire vehicle is the parking state, it determines whether the hydraulic lock module 20 needs to be unlocked, and when the hydraulic lock module 20 needs to be unlocked, controls the hydraulic lock module 20 to be unlocked, thereby ensuring the maintenance convenience of the entire vehicle.
[0059] It should be noted that the diversion cabin hydraulic lock control system also includes a power supply module for supplying power to various modules of the diversion cabin hydraulic lock control system, and the body domain control module 10 includes a CAN transceiver module for external communication.
[0060] In summary, the hydraulic lock control system for the deflector cabin of an embodiment of the present invention includes a vehicle body control module, a hydraulic lock module, and a switch module. The vehicle body control module includes a processing device and a sensor information acquisition device. The hydraulic lock module includes multiple lifting switches. The sensor information acquisition device is connected to the switch module and the lifting switch, respectively, to collect gear position information from the switch module and lifting switch status information. The processing device is connected to the sensor information acquisition device to obtain vehicle speed information, determine the vehicle's driving status based on the gear position and speed information, and control the hydraulic lock module to unlock or send an alarm based on the driving status and status information. In this technical solution, when driving, the hydraulic lock module is determined to be faulty based on the status information of the multiple lifting switches. If a fault occurs, an alarm is sent to the safety officer for monitoring or repair. This can avoid the risk of the deflector cabin tipping due to a hydraulic lock module failure, thereby improving driving safety. Alternatively, when parked, the hydraulic lock module is determined to be unlocked and automatically unlocked when required, ensuring easy maintenance of the vehicle.
[0061] It should be noted that the method of determining the status information of the plurality of lifting switches 210 in the parking state is different from the method of determining the status information of the plurality of lifting switches 210 in the driving state.
[0062] In the parking state, the vehicle is stopped. Upon receiving a hydraulic lock unlock command, the hydraulic lock module 20 can be unlocked. Specifically, the processing device 110 is also connected to multiple power-off switches 230. When repairs or maintenance work is required on the diversion cabin, the processing device 110 first determines whether a hydraulic lock unlock command has been received. Upon receiving the hydraulic lock unlock command, the processing device 110 controls the multiple power-off switches 230 to close. The processing device 110 then obtains the gear position information of the switch module 30 and the vehicle's speed information. If the gear position information of the switch module 30 indicates an on gear and the vehicle's speed information is equal to a first preset speed information, the vehicle's driving state can be determined to be the parking state. The first preset speed information can be 0. In the parking state, if the status information of multiple lifting switches are all in the closed state, it indicates that the hydraulic lock module 20 has not failed. After the multiple power-off switches 230 are closed, the hydraulic lock module 20 is unlocked normally; if the status information of at least one of the multiple lifting switches 210 is in the disconnected state, it indicates that the hydraulic lock module 20 has failed. The multiple power-off switches 230 remain in the disconnected state, keeping the hydraulic lock module 20 locked, and sending a first alarm message.
[0063] When the vehicle is in the driving state, the status information of multiple lifting switches 210 needs to be detected in real time. In the normal state, the multiple lifting switches 210 remain in the closed state, the hydraulic lock module 20 is locked, and the deflection cabin is fixed to the vehicle. Specifically, the processing device 110 obtains the gear information of the switch module 30 and the speed information of the vehicle. If the gear information of the switch module 30 is the on gear, and the speed information of the vehicle is greater than the first preset speed information, it can be determined that the vehicle is in the driving state. The first preset speed information can be 0. When driving, if the status information of multiple lifting switches 210 are all closed, it indicates that the hydraulic lock module 20 has not failed, the hydraulic lock module 20 is locked, the deflection cabin is fixed on the vehicle, and the vehicle is driving normally; if the number of lifting switches 210 with closed status information is less than the total number of lifting switches 210, it indicates that the hydraulic lock module 20 has failed, and some lifting switches 210 have abnormalities. At this time, the deflection cabin is still in a fixed state, but there is a risk of the deflection cabin tipping over. The vehicle can drive normally, but a second alarm message needs to be sent for real-time monitoring by the safety officer; if the status information of multiple lifting switches 210 are all disconnected, it indicates that the hydraulic lock module 20 has failed, all lifting switches 210 have abnormalities, and the risk of the deflection cabin tipping over is relatively high. At this time, a third alarm message needs to be sent and the vehicle needs to be stopped for inspection and maintenance by the safety officer.
[0064] On the basis of the above embodiment, continue to refer to Figure 1 The vehicle body control module 10 also includes a solenoid valve driver 130. The hydraulic lock module 20 also includes a solenoid valve 220, multiple power-off switches 230, and multiple hydraulic locks 240. The power-off switches 230 are normally open switches, and the lifting switch 210 is a normally closed switch. The processing device 110 is electrically connected to the solenoid valve driver 130 and is configured to control the operation of the solenoid valve 220 via the solenoid valve driver 130 to unlock the multiple hydraulic locks 240. The processing device 110 is also connected to the multiple power-off switches 230 to control the closing of the multiple power-off switches 230.
[0065] Specifically, the power-off switch 230 comprises a normally open switch, and the lifting switch 210 comprises a normally closed switch. Under normal circumstances, the lifting switches 210 are closed, and the power-off switches 230 are open. At this time, the solenoid valve drive device 130 is de-energized, the hydraulic locks 240 are locked, and the deflector cabin is fixed to the vehicle. Upon receiving a hydraulic lock unlock command, the processing device 110 controls the power-off switches 230 to close, energizing the solenoid valve drive device 130, which controls the solenoid valve 220 to actuate. The solenoid valve 220, through the flow of hydraulic oil from a hydraulic pump (not shown), controls the unlocking of the hydraulic lock module 20, and the deflector cabin is lifted, ready for maintenance or other maintenance work. In this way, when the hydraulic lock module 20 needs to be unlocked, it is unlocked, ensuring convenient maintenance of the vehicle.
[0066] Optionally, based on the above embodiment, continue to refer to Figure 1 The control system for the hydraulic lock of the diversion cabin also includes a dispatch information module 40, a telematics processor 50, and an intelligent driving domain controller 60. The telematics processor 50 is used to implement remote information transmission. The intelligent driving domain controller 60 is used to convert and transmit information. The telematics processor 50 is connected to the intelligent driving domain controller 60 and the dispatch information module 40, respectively. The intelligent driving domain controller 60 is connected to the processing device 110. The dispatch information module 40 is used to send command information to the processing device 110 or send alarm information to the safety officer's communication device.
[0067] Specifically, the telematics processor 50 is connected to the intelligent driving domain controller 60 and the dispatching information module 40, respectively, and the intelligent driving domain controller 60 is connected to the processing device 110 to realize communication between the processing device 110 and the outside. Among them, the dispatching information module 40 can be a port dispatching information module, which is used to process the information fed back by the processing device 110. The telematics processor 50 can be a vehicle-mounted T-BOX, which is mainly used to communicate with the communication device to realize remote transmission of information. The intelligent driving domain controller 60 is used to transmit the instruction information of the dispatching information module 40 to the processing device 110. In addition, the intelligent driving domain controller 60 can also directly send instruction information to the processing device 110. Furthermore, the processing device 110 feeds back the alarm information to the intelligent driving domain controller 60, the intelligent driving domain controller 60 transmits the alarm information to the remote information processor 50, and the remote processor 50 uploads the alarm information to the dispatching information module 40. The dispatching information module 40 then sends the alarm information to the safety officer's communication device to notify the safety officer to monitor or repair the entire vehicle. Alternatively, the dispatching information module 40 can send instruction information to the processing device 110 based on the status information of the multiple lifting switches 210 fed back by the processing device 110.
[0068] Exemplarily, the scheduling information module 40 can directly send a hydraulic lock unlocking instruction to the processing device 110 according to actual needs, so that the processing device 110 controls the hydraulic lock module 20 to unlock; or, in the parking state and when the processing device 110 receives the hydraulic lock unlocking instruction, if the status information of at least one of the multiple lifting switches 210 obtained by the processing device 110 is in a disconnected state, indicating that the hydraulic lock module 20 has failed and some of the lifting switches 210 have abnormalities, a first alarm message is sent to the scheduling information module 40, and the scheduling information module 40 sends the first alarm message to the safety officer's communication device for the safety officer to inspect and repair the hydraulic lock module 20; or, in the driving state, if the status information obtained by the processing device 110 is that the number of lifting switches 210 in the closed state is less than the total number of lifting switches 210, then it indicates that the hydraulic lock module 20 has failed. If there is a fault, some lifting switches 210 are abnormal, but the deflection cabin is still in a fixed state, and the whole vehicle can still drive normally, a second alarm message is sent to the dispatching information module 40, and the dispatching information module 40 sends a second alarm message to the safety officer's communication device for the safety officer to monitor the hydraulic lock module 20; or, in the driving state, if the status information of multiple lifting switches 210 obtained by the processing device 110 are all in the disconnected state, it indicates that the hydraulic lock module 20 has a fault, all lifting switches 210 are abnormal, and the risk of the deflection cabin tipping over is greater. At this time, a third alarm message is sent to the dispatching information module 40, and the dispatching information module 40 generates a parking command according to the third alarm message and sends it to the processing device 110, so that the processing device 110 controls the whole vehicle to stop, and at the same time sends a third alarm message to the safety officer's communication device for the safety officer to repair the hydraulic lock module 20. In this way, through the mutual communication between the processing device 110 and the scheduling information module 40, the scheduling information module 40 can perform unified scheduling management on the entire vehicle, facilitate timely detection of problems and carry out repairs, and improve the system's automation control and information management level.
[0069] It should be noted that the scheduling information module 40 can also be directly connected to the processing device 110 through the remote information processor 50, and then the scheduling information module 40 can send information to the processing device 110 through the remote information processor 50. The embodiment of the present invention does not limit the specific communication means between the scheduling information module 40 and the processing device 110, and those skilled in the art can set it as needed.
[0070] It should also be noted that the diversion cabin hydraulic lock control system may also include a storage module, which stores alarm information or instruction information to facilitate subsequent verification and maintenance by safety officers.
[0071] Optionally, based on the above embodiment, continue to refer to Figure 1The control system for the hydraulic lock of the diversion cabin also includes an onboard information display module 70, which is connected to the processing device 110 and is used to display alarm information. Specifically, the onboard information display module 70 can be installed on the entire vehicle, thereby allowing the safety officer to intuitively understand the vehicle's status, facilitating monitoring and maintenance of the vehicle.
[0072] Based on the same inventive concept, an embodiment of the present invention further provides a control method for a diversion cabin hydraulic lock control system, which is applied to the above-mentioned diversion cabin hydraulic lock control system. Figure 2 This is a flow chart of a control method for a diversion cabin hydraulic lock control system provided by an embodiment of the present invention. Figure 2 As shown, the control method includes:
[0073] S110: Acquire the gear position information of the switch module and the status information of the lifting switch.
[0074] Specifically, the switch module can be the starting switch of the entire vehicle, and the gear information of the switch module includes the four gears of the entire vehicle, namely LOCK, ACC, ON and START, namely, the lock gear, the accessory power-on gear, the connection gear and the start gear. The hydraulic lock module is used to lock the deflector cabin to ensure that the deflector cabin is fixed on the entire vehicle, thereby reducing the wind resistance of the entire vehicle during driving. The hydraulic lock module includes a plurality of lifting switches, and the plurality of lifting switches are used to control the unlocking of the hydraulic lock module. Exemplarily, the status information of the lifting switches includes a closed state and a disconnected state. When the status information of the plurality of lifting switches are all in a closed state, the hydraulic lock module has no fault, the deflector cabin is correctly positioned, and there is no risk of the deflector cabin tipping over; when the status information of the plurality of lifting switches is in a disconnected state, it indicates that the hydraulic lock module has a fault and the risk of the deflector cabin tipping over is greater.
[0075] S120: Obtain vehicle speed information.
[0076] There are other modules in the vehicle system for collecting the speed information of the vehicle. The processing device communicates with the module to obtain the speed information of the vehicle in real time.
[0077] S130: Determine the driving state of the vehicle according to the gear information and the speed information, and control the hydraulic lock module to unlock or send an alarm message according to the driving state and the state information.
[0078] Specifically, the processing device determines the driving state of the vehicle based on the acquired vehicle speed information and the gear position information of the switch module. For example, when the acquired gear position information of the switch module indicates that the vehicle is in the on gear and the vehicle speed information is 0, the vehicle is determined to be in the parked state. When the acquired gear position information of the switch module 30 indicates that the vehicle is in the on gear and the vehicle speed information is greater than 0, the vehicle is determined to be in the driving state. When the vehicle is determined to be in the driving state, the processing device determines whether the hydraulic lock module has failed based on the status information of the multiple lifting switches. If the hydraulic lock module fails, an alarm message is sent so that the safety officer can monitor or repair the hydraulic lock module through relevant measures. This can avoid the driving risk caused by the diversion cabin tipping due to the hydraulic lock module failure and improve driving safety. Alternatively, when the vehicle is determined to be in the parked state, the processing device determines whether the hydraulic lock module needs to be unlocked. If the hydraulic lock module needs to be unlocked, the processing device controls the hydraulic lock module to unlock, thereby ensuring the maintenance convenience of the vehicle.
[0079] In summary, the control method of the hydraulic lock control system of the deflector cabin of the embodiment of the present invention obtains the gear information of the switch module and the status information of the lifting switch, as well as the speed information of the entire vehicle, and determines the driving status of the entire vehicle according to the gear information and speed information, and controls the hydraulic lock module to unlock or send an alarm message according to the driving status and status information. In the above technical solution, in the driving state, the hydraulic lock module is judged to be faulty according to the status information of multiple lifting switches, and an alarm message is sent when the hydraulic lock module fails, so that the safety officer can monitor or repair the hydraulic lock module through relevant measures, thereby avoiding the driving risk caused by the deflector cabin tipping due to the failure of the hydraulic lock module, thereby improving the driving safety; or in the parking state, it is judged whether the hydraulic lock module needs to be unlocked, and when the hydraulic lock module needs to be unlocked, the hydraulic lock module is controlled to be unlocked, thereby ensuring the maintenance convenience of the entire vehicle.
[0080] It should be noted that when the hydraulic lock module fails, the processing device can also determine the cause of the failure of the hydraulic lock module. Specifically, the processing device obtains the current information of the lifting switch and the current information of the power-off switch, and determines the cause of the failure of the hydraulic lock module based on the current information of the lifting switch and the current information of the power-off switch. Exemplarily, the processing device is provided with preset current information. If the current information of the lifting switch obtained is less than the preset current information, it indicates that the corresponding lifting switch has failed. If the current information of the lifting switch is greater than the preset current information, it indicates that the corresponding lifting switch is in a normal state. In addition, the corresponding cause of the failure can also be displayed through the on-board information display module to facilitate the safety officer to perform targeted repairs according to the cause of the failure, further ensuring the maintenance convenience of the entire vehicle.
[0081] Further, Figure 3FIG. 1 is a flow chart of another control method of a hydraulic lock control system for a diversion cabin provided by an embodiment of the present invention. Figure 3 As shown, the control method includes:
[0082] S210: Determine whether a hydraulic lock unlocking instruction is received. If a hydraulic lock unlocking instruction is received, control the multiple power-off switches to be closed. If no hydraulic lock unlocking instruction is received, control the multiple power-off switches to remain in an open state.
[0083] Specifically, the scheduling information module can directly send a hydraulic lock unlock command to the processing device based on actual needs, causing the processing device to control the hydraulic lock module to unlock. For example, receipt of the hydraulic lock unlock command indicates that repair or maintenance work on the diversion cabin is required. The processing device determines whether the hydraulic lock unlock command has been received and, if so, controls multiple power-off switches to close. If not, the multiple power-off switches remain open.
[0084] S220: Obtain the gear position information of the switch module and the status information of the lifting switch.
[0085] S230: Obtain vehicle speed information.
[0086] S240: If the gear position information indicates an engaged gear and the speed information is equal to the first preset speed information, it is determined that the driving state is a parking state.
[0087] Specifically, if the gear position information of the switch module is the on gear and the speed information of the vehicle is equal to the first preset speed information, it can be determined that the driving state of the vehicle is the parking state. The first preset speed information can be 0.
[0088] S250: In the parking state, if the status information of multiple lifting switches are all closed, control the hydraulic lock module to unlock.
[0089] Specifically, in the parking state, if the status information of multiple lifting switches are all closed, it indicates that the hydraulic lock module has not failed and the hydraulic lock module is unlocked normally. The power-off switch includes a normally open switch, and the lifting switch includes a normally closed switch. Under normal circumstances, multiple lifting switches are in a closed state and multiple power-off switches are in a disconnected state. At this time, the solenoid valve drive device is powered off, multiple hydraulic locks are locked, and the deflector cabin is fixed to the entire vehicle. When a hydraulic lock unlocking instruction is received, the processing device controls the multiple power-off switches to close, the solenoid valve drive device is powered, and the solenoid valve is controlled to operate. The solenoid valve controls the multiple hydraulic locks to unlock through the flow of hydraulic oil in the hydraulic pump. The unlocking process of the hydraulic lock module is completed, the deflector cabin is lifted, and maintenance or status maintenance can be carried out. In this way, when the hydraulic lock module needs to be unlocked, the hydraulic lock module is controlled to unlock, ensuring the maintenance convenience of the entire vehicle.
[0090] S260. In the parking state, if the status information of at least one of the multiple lifting switches is in the disconnected state, keep the hydraulic lock module locked and send a first alarm message to the dispatching information module, so that the dispatching information module sends the first alarm message to the safety officer's communication device.
[0091] In the parking state, if the status information of at least one of the multiple lifting switches is disconnected, it indicates that the hydraulic lock module has a fault. If some lifting switches appear, the hydraulic lock module will be locked and a first alarm message will be sent to the scheduling information module. The scheduling information module will send the first alarm message to the safety officer's communication device so that the safety officer can inspect and repair the hydraulic lock module.
[0092] In summary, in the embodiment of the present invention, it is first determined whether a hydraulic lock unlocking instruction has been received. If a hydraulic lock unlocking instruction has been received, multiple power-off switches are controlled to close, and then the gear information of the switch module and the status information of the lifting switch and the speed information of the entire vehicle are obtained, and it is determined whether the driving state of the entire vehicle is the parking state. In the parking state, if the status information of the multiple lifting switches are all closed, the hydraulic lock module is controlled to unlock; in the parking state, if the status information of at least one of the multiple lifting switches is disconnected, the hydraulic lock module is kept locked, and a first alarm message is sent to the dispatch information module, so that the dispatch information module sends the first alarm message to the safety officer's communication device. In the above technical solution, only when the hydraulic lock unlocking instruction is received and the driving state of the entire vehicle is the driving state, it is determined whether the hydraulic lock module needs to be unlocked, thereby improving safety. In addition, when the hydraulic lock module needs to be unlocked, the hydraulic lock module is automatically controlled to unlock, thereby ensuring the maintenance convenience of the entire vehicle.
[0093] Further, Figure 4 FIG. 1 is a flow chart of another control method of a hydraulic lock control system for a diversion cabin provided by an embodiment of the present invention. Figure 4 As shown, the control method includes:
[0094] S310: Acquire the gear position information of the switch module and the status information of the lifting switch.
[0095] S320: Obtain vehicle speed information.
[0096] S330: If the gear position information indicates an engaged gear and the speed information is greater than the first preset speed information, the driving state is determined to be a moving state.
[0097] If the gear position information of the switch module indicates an on gear and the vehicle's speed is greater than a first preset speed information, the vehicle's driving state can be determined to be in the driving state. The first preset speed information can be 0. When the vehicle's driving state is in the driving state, the status information of multiple lifting switches must be checked in real time. Under normal conditions, all lifting switches remain closed, the hydraulic lock module is locked, and the diversion cabin is fixed to the vehicle, preventing the cabin from tipping over. If the lifting switches are disconnected, this indicates a malfunction in the hydraulic lock module.
[0098] S340. In the driving state, if the status information indicates that the number of lifting switches in the closed state is less than the total number of lifting switches, a second alarm message is sent to the dispatching information module so that the dispatching information module sends the second alarm message to the safety officer's communication device.
[0099] If the number of lifting switches in the closed state is less than the total number of lifting switches, it indicates that the hydraulic lock module has failed and some lifting switches have abnormalities. Although the diversion cabin is still in a fixed state, there is a risk of the diversion cabin tipping over. The entire vehicle can drive normally, and a second alarm message needs to be sent to the dispatching information module. The dispatching information module sends the second alarm message to the safety officer's communication device so that the safety officer can monitor the hydraulic lock module.
[0100] S350. In the driving state, if the status information of multiple lifting switches are all disconnected, send a third alarm message to the dispatching information module, so that the dispatching information module generates a parking instruction and sends the third alarm message to the safety officer's communication device.
[0101] If the status information of multiple lifting switches are all in the disconnected state, it indicates that the hydraulic lock module has failed. If all lifting switches are in the disconnected state, there is a high risk of the diversion cabin tipping over. At this time, if the entire vehicle continues to drive, the diversion cabin will tip over, endangering the personal safety of the safety officer and damaging the port container. Then the control device sends a third alarm message to the dispatching information module. The dispatching information module generates a parking command based on the third alarm message and sends it to the processing device, so that the processing device controls the entire vehicle to stop. At the same time, the third alarm message is sent to the safety officer's communication device for the safety officer to inspect and repair the hydraulic lock module.
[0102] S360: Obtain speed information according to the parking instruction, and control the entire vehicle to stop when the speed information is greater than second preset speed information.
[0103] Specifically, after the processing device receives the parking instruction, it does not immediately control the vehicle to stop. Instead, it determines whether the vehicle's speed information is greater than the second preset speed information. The second preset speed information is greater than the first preset speed information, and the second preset speed information can be 10km / h. If the vehicle's speed information is greater than the second preset speed information, it indicates that the vehicle's speed is relatively high at this time, and the diversion cabin may tip over, thereby endangering the safety of the safety officer and damaging the port container. In this case, the vehicle is controlled to stop. If the vehicle's speed information is less than or equal to the second preset speed information, it indicates that the vehicle's speed is relatively low at this time, and the risk of endangering the safety of the safety officer and damaging the port container is relatively low. In this case, the vehicle can be controlled to continue driving at this speed. In this way, the normal operation of the vehicle is ensured while improving the safety of the vehicle.
[0104] It should be noted that when driving, if the status information of multiple lifting switches are all closed, it means that the hydraulic lock module has not failed, the hydraulic lock module is locked, the deflection cabin is fixed on the vehicle, and the vehicle is driving normally, and there is no need to send an alarm message.
[0105] In summary, the embodiment of the present invention obtains the gear information of the switch module, the status information of the lifting switch, and the speed information of the vehicle. If the gear information is the on gear and the speed information is greater than the first preset speed information, the driving state is determined to be the driving state. In the driving state, if the number of lifting switches with closed status information is less than the total number of lifting switches, a second alarm message is sent to the dispatching information module, so that the dispatching information module sends the second alarm message to the safety officer's communication device. In the driving state, if the status information of multiple lifting switches are all disconnected, a third alarm message is sent to the dispatching information module, so that the dispatching information module generates a parking instruction and sends the third alarm message to the safety officer's communication device. The processing device obtains the speed information based on the parking instruction and controls the vehicle to stop when the speed information is greater than the second preset speed information. The above technical solution determines the status information of multiple lifting switches in real time when the vehicle is in the driving state, and issues an alarm when the hydraulic lock module fails, so as to notify the safety officer to monitor or repair the hydraulic lock module. This can avoid the driving risk caused by the diversion cabin tipping due to the failure of the hydraulic lock module, thereby improving driving safety.
