[0046] Embodiment 1
[0047] Figure 1 A flowchart of a method for controlling a mining dump truck is provided for the first embodiment of the present invention. This embodiment is applicable to the case of emergency shutdown of a mining dump truck. The method for controlling a mining dump truck can be executed by a control device for a mining dump truck. The control device for a mining dump truck can be implemented in the form of hardware and / or software. The control device for a mining dump truck can be configured in a mining dump truck. Figure 1 As shown, the control method of the mining dump truck includes:
[0048] S110. Acquire vehicle operation information of the mining dump truck during normal operation of the mining dump truck, and generate an emergency shutdown instruction of the mining dump truck based on the vehicle operation information.
[0049] Among them, the vehicle operation information may include the engine compartment ambient temperature, brake air pressure, brake pedal opening, engine speed and wheel speed. The engine compartment ambient temperature, brake air pressure, brake pedal opening, engine speed and wheel speed can be obtained through existing data collection methods, and this embodiment does not impose any restrictions on this.
[0050] In this embodiment, during the normal operation of the mining dump truck, one or more combinations of the collected engine compartment ambient temperature, brake air pressure, brake pedal opening, engine speed and wheel speed are used to determine whether an emergency shutdown command for the mining dump truck is generated by the emergency control system of the mining dump truck.
[0051] Specifically, if the ambient temperature of the engine compartment exceeds the first set ambient temperature alarm value within the set detection time length, an emergency shutdown command of the mining dump truck is generated; or, if the brake air pressure is within the set pressure range and the brake pedal opening exceeds the set opening threshold, an emergency shutdown command of the mining dump truck is generated; or, if the ratio of the engine speed to the wheel speed is not equal to the set alarm value, an emergency shutdown command of the mining dump truck is generated.
[0052] On the basis of the above, if the vehicle operation information of the mining dump truck obtained during the normal operation of the mining dump truck is the engine compartment ambient temperature, when the engine compartment ambient temperature exceeds the second set ambient temperature alarm value, an alarm is issued through the dashboard of the mining dump truck; wherein the first set ambient temperature alarm value is greater than the second set ambient temperature alarm value.
[0053] S120, controlling the power distribution system of the mining dump truck to cut off power based on the emergency shutdown command, and obtaining the current speed of the mining dump truck after receiving the emergency shutdown command.
[0054] On the above basis, after the emergency shutdown command of the mining dump truck is generated by the emergency control system of the mining dump truck, the power distribution system of the mining dump truck is powered off after the emergency control system triggers the emergency shutdown command, that is, the emergency shutdown command is used to control the power distribution system of the mining dump truck to power off.
[0055] It is understandable that in order to ensure the emergency shutdown and stable parking of the mining dump truck at this time, the power distribution system must retain the power supply to the emergency braking system, emergency steering system, and alarm system, while all other power distribution of the entire machine is cut off to avoid further accidents of mining dump trucks due to circuit failures, which would cause the engine to lose power and shut down.
[0056] The current vehicle speed is the speed of the mining dump truck detected in real time after receiving the emergency shutdown command. The specific method for obtaining the current vehicle speed can be implemented according to the function of the mining dump truck itself, and this embodiment does not impose any limitation on this.
[0057] S130, according to the current vehicle speed, controlling the emergency braking system of the mining dump truck to be enabled or the emergency steering module to be disabled and the whole machine power supply to be disconnected, so as to control the mining dump truck to stop stably.
[0058] Specifically, if the current vehicle speed is greater than the set vehicle speed threshold, the emergency control system of the mining dump truck automatically controls the emergency braking system of the mining dump truck to be enabled, so as to control the mining dump truck to stop stably.
[0059] Among them, setting the vehicle speed threshold is used to determine whether the mining dump truck can automatically trigger the emergency braking system at this time. The vehicle speed threshold can be set by referring to the speed limit value of the mining dump truck automatically triggering the emergency braking system obtained in the experiment. This embodiment does not impose any restriction on the specific value of the speed threshold.
[0060] Optionally, the vehicle speed threshold may be set to 5 km / h. When the vehicle speed is greater than or equal to 5 km / h, the emergency braking system of the mining dump truck is automatically activated through the emergency control system of the mining dump truck to control the mining dump truck to stop stably.
[0061] On the above basis, after the emergency braking system of the mining dump truck is activated, the mining dump truck is controlled to decelerate at a set deceleration value until the mining dump truck stops quickly and stably.
[0062] Among them, the set deceleration value is used to determine whether the mining dump truck can stop quickly and stably at this time. The set deceleration value can be selected and set by referring to the deceleration limit value for the rapid and stable parking of the mining dump truck obtained from the experiment. This embodiment does not impose any restrictions on the specific numerical value of the set deceleration value.
[0063] Furthermore, if the current vehicle speed is 0, the emergency control system of the mining dump truck controls the emergency steering module of the mining dump truck to be disabled and the power supply of the entire machine is disconnected to ensure the safety of the mining dump truck.
[0064] If the current vehicle speed is not 0, the emergency steering module of the mining dump truck is activated, the emergency steering motor is started, the emergency steering pump is turned on, and the emergency steering system starts working to ensure that the vehicle still has the ability to steer after losing power. The driver can move the vehicle to the roadside or a safe area, thereby achieving stable parking of the mining dump truck.
[0065] On the basis of the above embodiment, after the emergency shutdown command is triggered, the alarm system of the mining dump truck can trigger the working warning light and the four-flash alarm light to flash, thereby reminding other vehicles to avoid the current mining dump truck.
[0066] It should also be noted that after the fault of the mining dump truck is eliminated, the emergency shutdown switch can be reset, and the emergency control system of the mining dump truck can control the power distribution module to distribute power normally, thereby eliminating the alarm of the alarm system and allowing the mining dump truck to return to normal working state.
[0067] The technical solution of the embodiment of the present invention obtains the vehicle operation information of the mining dump truck during the normal operation of the mining dump truck, and generates an emergency shutdown command of the mining dump truck based on the vehicle operation information; controls the power distribution system of the mining dump truck to be powered off based on the emergency shutdown command, and obtains the current speed of the mining dump truck after receiving the emergency shutdown command; controls the emergency braking system of the mining dump truck to be enabled or the emergency steering module to be disabled and the power supply of the whole machine to be disconnected according to the current speed, so as to control the mining dump truck to stop stably. The present invention solves the problem that the current mining dump truck has a slow response speed when encountering a major fault, and the fault range is easily expanded when the power system is running, realizes the emergency shutdown control of the mining dump truck, and ensures the safe driving of the mining dump truck.
[0068] Embodiment 2
[0069] Figure 2 This is a flowchart of a method for controlling a mining dump truck provided in the second embodiment of the present invention. Based on the above embodiment, this embodiment generates an emergency shutdown command for a mining dump truck based on different vehicle operation information, providing an optional implementation method. Figure 2 As shown, the control method of the mining dump truck includes:
[0070] S210, normal operation process of a mining dump truck.
[0071] S220: Acquire vehicle operation information of the mining dump truck as an engine compartment ambient temperature.
[0072] S221. Determine whether the ambient temperature of the engine compartment exceeds a second set ambient temperature alarm value. If so, execute step S222; if not, execute step S220.
[0073] Among them, the second set ambient temperature alarm value is used to determine whether the engine compartment of the mining dump truck is in a high temperature state at this time. The second set ambient temperature alarm value can be selected and set with reference to the temperature limit value of the mining dump truck in a high temperature state obtained from the experiment. This embodiment does not impose any restriction on the specific numerical value of the second set ambient temperature alarm value.
[0074] In this embodiment, if the ambient temperature of the engine compartment does not exceed the second set ambient temperature alarm value, the vehicle operation information of the mining dump truck continues to be obtained.
[0075] S222. Alarm through the dashboard of the mining dump truck.
[0076] Specifically, when the ambient temperature of the engine compartment exceeds the second set ambient temperature alarm value, the emergency control system of the mining dump truck communicates with the instrument panel, and then alarms through the instrument panel of the mining dump truck that the engine compartment is in a high temperature state, so that the user of the mining dump truck or relevant technical personnel can take corresponding measures in time.
[0077] It can be known that the alarm mode of the instrument panel can be implemented according to the instrument panel function of the mining dump truck itself, and this embodiment does not impose any limitation on this.
[0078] S223, determine whether the ambient temperature of the engine compartment exceeds the first set ambient temperature alarm value within the set detection time length, if so, execute step S224, if not, execute step S220.
[0079] Among them, the first set ambient temperature alarm value is used to determine whether the mining dump truck will spontaneously combust at this time. The first set ambient temperature alarm value can be selected and set with reference to the temperature limit value for spontaneous combustion of the mining dump truck obtained from the experiment. This embodiment does not impose any restriction on the specific numerical value of the first set ambient temperature alarm value.
[0080] Similarly, the detection time length may be set by referring to the detection time length limit of spontaneous combustion of a mining dump truck obtained from an experiment. This embodiment does not impose any restriction on the specific value of the detection time length.
[0081] Specifically, if the ambient temperature of the engine compartment does not exceed the first set ambient temperature alarm value within the set detection time length, the vehicle operation information of the mining dump truck continues to be obtained.
[0082] S224, generate an emergency shutdown instruction for the mining dump truck, and execute step S250.
[0083] Specifically, if the ambient temperature of the engine compartment exceeds a first set ambient temperature alarm value within a set detection time, it is determined that the vehicle may spontaneously combust, and an emergency shutdown command for the mining dump truck is generated through the emergency control system of the mining dump truck.
[0084] S230: Acquire vehicle operation information of the mining dump truck, which includes brake air pressure and brake pedal opening.
[0085] S231. Determine whether the brake air pressure is within the set pressure range and whether the brake pedal opening exceeds the set opening threshold. If so, execute step S232; if not, execute step S230.
[0086] Among them, the set pressure range and the set opening threshold are used to determine whether the main brake system of the mining dump truck will fail at this time. The set pressure range can be selected and set by referring to the set pressure range of failure of the main brake system of the mining dump truck obtained from the test. This embodiment does not impose any restriction on the specific value of the set pressure range.
[0087] Similarly, the opening threshold is set to determine whether the main brake system of the mining dump truck will fail at this time. The opening threshold can be set by referring to the set opening limit of the failure of the main brake system of the mining dump truck obtained from the experiment. This embodiment does not impose any restriction on the specific value of the set opening threshold.
[0088] Specifically, if the brake air pressure is not within the set pressure range, or the brake pedal opening does not exceed the set opening threshold, the vehicle operation information of the mining dump truck continues to be obtained.
[0089] S232, generate an emergency shutdown instruction for the mining dump truck, and execute step S250.
[0090] Specifically, if the brake air pressure is within the set pressure range and the brake pedal opening exceeds the set opening threshold, it is determined that the main braking system of the entire machine has failed, and an emergency shutdown command for the mining dump truck is generated through the emergency control system of the mining dump truck.
[0091] It should be noted that before executing step S232, it is also necessary to determine that the deceleration of the mining dump truck at this time is greater than the set deceleration threshold. The deceleration threshold can be selected and set by referring to the set opening limit of the failure of the main braking system of the mining dump truck obtained from the experiment. This embodiment does not impose any restrictions on the specific value of the set deceleration threshold.
[0092] S240: Obtain vehicle operation information of the mining dump truck, which includes engine speed and wheel speed.
[0093] S241. Determine whether the ratio of the engine speed to the wheel speed is not equal to the set alarm value. If so, execute step S242; if not, execute step S240.
[0094] Among them, the set alarm value is used to determine whether the transmission shaft of the entire transmission system of the mining dump truck will be damaged at this time. The set alarm value can be selected and set by referring to the alarm value limit of the transmission shaft damage of the entire transmission system of the mining dump truck obtained from the experiment. This embodiment does not impose any restrictions on the specific numerical value of the set alarm value.
[0095] Specifically, if the ratio of the engine speed to the wheel speed is equal to the set alarm value, the vehicle operation information of the mining dump truck continues to be obtained.
[0096] S242, generate an emergency shutdown instruction for the mining dump truck, and execute step S250.
[0097] Specifically, if the ratio of the engine speed to the wheel speed is not equal to the set alarm value, it is considered that the drive shaft of the entire machine transmission system is damaged, and an emergency shutdown command of the mining dump truck is generated through the emergency control system of the mining dump truck.
[0098] S250, controlling the power distribution system of the mining dump truck to cut off power based on the emergency shutdown command, and obtaining the current speed of the mining dump truck after receiving the emergency shutdown command.
[0099] S260, according to the current vehicle speed, the emergency braking system of the mining dump truck is controlled to be enabled or the emergency steering module is controlled to be disabled and the power supply of the whole machine is disconnected, so as to control the mining dump truck to stop stably.
[0100] Specifically, if the current vehicle speed is greater than a set vehicle speed threshold, the emergency braking system of the mining dump truck is controlled to be enabled; further, the mining dump truck is controlled to decelerate at a set deceleration value until the mining dump truck stops stably.
[0101] If the current vehicle speed is 0, the emergency steering module of the mining dump truck is controlled not to be enabled and the power supply of the whole machine is disconnected.
[0102] If the current vehicle speed is not 0, the emergency steering module of the mining dump truck is controlled to be enabled to control the mining dump truck to stop stably.
[0103] The technical solution of the embodiment of the present invention can cut off the power supply and power source of the mining dump truck in the shortest time when a serious fault occurs in the mining dump truck, thereby reducing the loss of the mining dump truck to a minimum, effectively protecting the mining dump truck, and improving the driving safety of the mining dump truck.
