High-level firefighting rescue equipment equipped with voice alerts that inform the driver of the relevant matters and important driving conditions of the ladder.

As the population is concentrated in large cities due to industrial development and urbanization in recent years, dense and high-rise residential areas and many vehicles are parked on roads in residential areas, making it difficult for fire trucks to enter in case of fire. This is true.

Up to now, the most commonly used as a life-saving equipment in the fire of high-rise buildings has been the high ladder fire truck, which is a large special truck combined with a ladder device made of a welded trust structure, and the ladder is standing up. And at least four outriggers, usually 5 meters or more, on the left and right sides of the fire truck to prevent and overturn the fire truck when it is extended, and lift the body against the ground when the ladder is used. To make it more stable.

Figure 1 is a side view of a conventional high ladder fire truck (1), Figure 2 shows a state in which the elevated ladder (2) of the elevated ladder fire truck 1 of Figure 1 is standing up, and Figure 3 is an outrigger (11) ) Shows a state of supporting the fire engine 1 in contact with the ground.

1 and 2, the high ladder fire truck 1 includes a turntable rotatably mounted by a ladder device 2 and a chassis 5 in a large body-mounted truck. The ladder device 2 comprises a main ladder part 3 attached to a vehicle body and a high ladder part 4 telescopically coupled to the main ladder part 3.

The turntable 6 is provided with an operator cockpit and a control panel, the main ladder part 3 of which the lower end part is fixed to the turntable 6 by a hinge and the high ladder part by the boom cylinder 9. Stand and rotate with the field (4). In recent years, it has become common to adopt a high ladder device that is extended to a maximum of 52 m in a high ladder fire truck.

On the other hand, the elevator 10 is installed on the upper surface of the ladder device 2, the winch mechanism 7 for the vertical movement of the elevator 10 is provided on one side of the main ladder portion (3). Is provided. The winch mechanism 7 mainly uses a hydraulic winch that converts engine power in the vehicle itself into hydraulic pressure.

In addition, by turning the turntable 6 horizontally, the ladder apparatus 2 can be directed in the direction in which fire suppression is necessary in a state where the position of the fire engine 1 is fixed, and the high ladder portion 4 is stretched or refracted. In this way, the windows 8 can be brought closer to the fire site to extinguish the fire.

However, when the ladder is deployed, the driver always pays attention to the length of the ladder and the standing angle as the ladder rotates, expands, and climbs and descends, so that the fire truck can not bear the load of the ladder. It costs.

In particular, in the case of fire trucks on the market, the deployment width of a given outrigger is limited to 5.2 m meters so that the operating state of the straight ladder (see FIGS. 1 and 2) or the articulated ladder (see FIGS. 6 and 7) is limited. Therefore, there is a risk of vehicle overturning, so very careful driving is required for the stability of the equipment.

In the conventional high ladder fire truck, the driver grabs the steering wheel and deploys a ladder device to view and manipulate various information displayed on the cockpit's monitor screen (see FIG. 4). In this light, it was difficult to read the message on the screen. In addition, even though the monitor screen is visible, the driver has a problem that it is practically difficult for the driver to check the state of the equipment such as a high ladder through the monitor screen in consideration of the very urgent situation of the disaster site.

The present invention, in order to solve the above problems, in the elevated ladder fire truck or high-refractive ladder fire truck to display the various safety-related matters and the operation state when operating the ladder with a monitor and at the same time to inform the driver in a dangerous situation The objective is to provide expensive firefighting lifesaving equipment that ensures quick recognition and ensures safety by stopping further operation once the operation of the high ladder is in danger.

When the main screen is displayed on the monitor 20, it is displayed as shown in FIG. 4, and in addition, menus of the parameter 22, the equipment operation 23, the weight setting 24, and the level 25 are provided. According to the main screen, the current height of the ladder is 4m, the length is 10m, and the angle is 1.8 °.

Refractive or straight type ladders are equipped with 8 safety devices to prevent accidents caused by the driver's carelessness.However, even if there are automated safety devices, they are large due to the failure of the safety devices and program errors. There is a possibility that an accident may occur.

In addition, since all safety devices of the high ladder fire truck operate normally only during automatic driving, automatic driving cannot be performed in narrow streets where the outrigger 11 is not developed as much as a predetermined maximum length. Great care must be taken because deployment is required. In addition, even during automatic operation, the safety device does not detect a danger due to an obstacle, an abnormal wind direction, or a load exceeding the rated load, and there is a problem that the driver should look for.

Therefore, the present invention is in danger of falling off the center of gravity of the entire fire truck when the ladder reaches the safety limit area, i.e., when the ladder is laid over the permitted angle or extended beyond the permitted length during manual operation. If the ladder touches an obstacle or the wind speed is too high, or if the wind speed exceeds the rated load, an alarm is displayed on the monitor and the driver is notified by voice that the safety device limit has been reached.
