Example 8:
as shown in fig. 8, the present embodiment provides a box door alarm control method, which employs the box door alarm control system according to any embodiment of the present invention, and in addition to the technical features of embodiment 7, the present embodiment further includes the following technical features.
The vehicle state includes a vehicle running state, a vehicle power take-off state, and a vehicle gear state. The controller is according to the switching of the second alarm device of the vehicle state control chamber door alarm control system of work vehicle, specifically includes:
step S302, controlling a second alarm device to be started and give an alarm by a controller based on the vehicle running state;
and step S304, based on the vehicle running state that the vehicle does not run, the controller controls the second alarm device to be opened and closed according to the power taking state and the gear position state of the vehicle.
In the present embodiment, the vehicle running state includes two states of vehicle running and vehicle non-running. The vehicle power take-off state comprises two states of vehicle on-board power take-off and vehicle chassis power take-off. The vehicle gear state is that the vehicle is in neutral or the vehicle is switched to neutral, and the vehicle is not in neutral or the vehicle is switched to the non-neutral.
Based on the fact that the opening and closing state is that part of the door is not closed and the vehicle running state is that the vehicle runs, the door is not completely or completely closed, so the second alarm device is controlled to be opened and give an alarm in this case. If the opening and closing state is that part of the box doors are not closed and the vehicle running state is that the vehicle does not run, the box doors may be opened because the rescue workers take and place the rescue equipment. At the moment, the second alarm device is controlled to be opened and closed according to the power taking state and the gear state of the vehicle, so that misjudgment and interference on rescuers are avoided.
Example 9:
as shown in fig. 9, the present embodiment provides a box door alarm control method, which employs the box door alarm control system according to any embodiment of the present invention, and in addition to the technical features of embodiment 8, the present embodiment further includes the following technical features.
The controller is according to the switching of vehicle power takeoff state and vehicle gear state control second alarm device, specifically includes:
step S402, controlling a second alarm device to be closed by a controller based on the vehicle power take-off state as the vehicle power take-off state;
step S404, based on the power take-off state of the vehicle as the power take-off of the vehicle chassis and the gear state of the vehicle as the non-neutral gear of the vehicle or the switching of the vehicle to the non-neutral gear, the controller controls the second alarm device to be started and give an alarm;
and S406, based on the power taking state of the vehicle, power is taken from the chassis of the vehicle, the gear state of the vehicle is in neutral gear of the vehicle or the vehicle is switched to neutral gear, the controller controls the second alarm device to be started and give an alarm, and controls a second relay coil of the box door alarm control system to be disconnected, a normally closed contact of the second relay is closed, a time delay relay coil is closed, and a normally open contact of the time delay relay is opened, so that the second alarm device is closed in a time delay mode after being started.
Based on the vehicle running state being that the vehicle is not running, the present embodiment further determines the vehicle power take-off state and the vehicle gear position state. Wherein the vehicle on-board power take off indicates that the work vehicle 100 is performing rescue, and therefore controls the second warning device to turn off at this time. Based on the vehicle driving state being that the vehicle is not driving and the vehicle power take-off state being that the vehicle chassis power take-off, the vehicle gear state needs to be further judged. Specifically, if the vehicle gear state is that the vehicle is not in neutral or the vehicle is shifted to non-neutral, it indicates that the work vehicle 100 is traveling or is about to start, and the door opening at this time is abnormal, so the second warning device is controlled to open and warn. Accordingly, if the power take-off state of the vehicle is the power take-off state of the vehicle chassis, and the gear state of the vehicle is the neutral gear of the vehicle or the vehicle is switched to the neutral gear, the second warning device needs to be turned off after being turned on in a delayed manner. Thereby. When a driver gets off the vehicle and puts the vehicle into the neutral position before closing the door, the delay relay delays for a certain time and then cuts off the power, the audible and visual alarm continues to light and buzzes, and after a certain time, the audible and visual alarm stops working. The specific time of the delay may be 60 seconds or 40 seconds or 80 seconds.
