The present invention relates to an elevator mischief warning device.

Description of the Related Art In general, an elevator is forcibly excited by a passenger due to the mischief of a passenger, and when the vibration becomes remarkable, a safety device (governor) operates to lead to an accident that the passenger is trapped in the elevator. Therefore, before the safety device malfunctions, for example, the acceleration of the car is detected, and if it exceeds the judgment value, the buzzer sounds or the lights in the car are turned off, and the passengers Techniques for stopping forced excitation are known. Japanese Patent Application Laid-Open No. 6-24663 is an example of this conventional technique.

ねを数回繰り返し、乗りかごが揺れ始めたらその揺れに
合わせて膝の屈伸を行うため、加速度が判定値を超えて
警告を発するまでには数秒〜１０秒程度を要する。In the above conventional example, in order to prevent a warning from being erroneously issued due to the vibration of the normal running, the acceleration determination value for determining whether or not to generate the warning must be increased to some extent. Also, to shake the car, the passenger repeats jumping several times, and when the car starts to shake, it flexes and stretches the knee according to the swing, so it takes a few seconds to raise the warning when the acceleration exceeds the judgment value and issues a warning. It takes about 10 seconds.

の印象を与えかねない。However, in order to stop such mischief, it is more effective to issue a warning immediately after the mischief is started. However, if the determination value of the acceleration of the car is reduced for this reason, a warning is erroneously issued due to the vibration of the normal traveling. Further, in the warning for turning off the light in the car, it is desirable that the light be turned off for a few seconds or more as a stopping effect. However, if another passenger rides on the car, it may give an impression that the warning is excessive.

It is an object of the present invention to provide a mischief warning device for stopping mischief before reaching a second warning that passengers feel excessive.

り低く設定する。The object of the present invention is to provide, in addition to the means for detecting the acceleration of the car, means for detecting the load of the car, wherein the acceleration of the car is set to a predetermined value. At that point, the value of the load on the car is checked, it is determined whether or not the fluctuation is caused by the forced vibration of the passenger, and in the case of the forced vibration, a warning is issued. The warning at this time is not a turning off of the lighting for several seconds or more, but a minor warning such as turning off the lighting for one second. Also, the preset acceleration determination value is set lower than in the conventional example.

いたずらによる強制加振によっても動作する。[0009] The raising and lowering of the car is operated by feeding and removing oil into and from the hydraulic cylinder 2. For this purpose, an oil pipe is connected to the hydraulic cylinder 2 via a motor, an oil pump and a hydraulic control valve (not shown in the drawing). In addition, emergency stop device 12
Is operated to stop the car 1 when the car 1 descends at an abnormal speed (including when the car rope 11 is broken). The governor 5 detects this speed. However, the governor 5 also operates by forced vibration due to mischief of a passenger.

１に示す。始めに、走行前の乗りかごの積載荷重の測定
(１０１）した後に、走行を開始（１０２）する。For this reason, in the conventional example, the speed and acceleration of the car 1 are calculated by periodically detecting the position of the car 1 from the rotary encoder 6, and the governor 5 is controlled.
When approaching the acceleration at which the camera operates, the light 8 is turned off.
It was to stop the mischief. However, in order to stop the mischief, it is more effective to issue a warning immediately after the mischief starts. However, if the determination value of the acceleration is lowered, a warning is erroneously issued due to the vibration generated due to the bending of the guide rail 13 or the like. For this reason, in the present embodiment, it is determined whether or not to issue a warning in consideration of the amount of change in the loaded load of the car 1 instead of simply decreasing the determination value of the acceleration. This processing flow is shown in FIG. First, measure the load on the car before traveling
After (101), running is started (102).

のような厳重な警告である。During traveling, the acceleration of the car is measured (10
3), the load on the car is measured (104) at all times, and it is checked whether the acceleration of the car 1 exceeds the second determination value (105). The second determination value is a value lower than the governor 5 operates and larger than the vibration of the normal traveling.
This is the value used in the conventional example. If it exceeds the second determination value, a second warning (110) is issued, and then the vehicle is driven (111) to the nearest floor. The second warning is a strict warning as in a conventional example in which the car 1 is stopped and the light 8 is turned off for several seconds.

せない警告で、第２の警告より軽微なものである。If it does not exceed the second judgment value, it is checked whether the acceleration of the car has exceeded the first judgment value (106). The first determination value is a value that is approximately equal to the maximum value of the vibration during normal traveling. If it does not exceed the first determination value, the process proceeds to the end of traveling (109). If it exceeds the first determination value, it is checked whether the increase and decrease of one passenger has occurred three times or more within three seconds with the load of the car (107). If No, the process ends or proceeds to (109). If Yes, the first warning is given, and then the process proceeds to the end of traveling (109). The first warning is, for example, a warning that the light 8 is turned off for one second and the car 1 is not stopped, and is a lighter warning than the second warning.

The warning may be generated earlier as the number of times or more. In addition,
The load detection device 9 is originally provided for detecting an excess load, and is not specially provided for the present embodiment. Therefore, the present embodiment can be implemented without increasing the cost. Can be done.

る。The present invention determines whether or not to apply forced vibration in consideration of not only the acceleration of the car but also the change in the load of the car. The driving vibration is not erroneously determined as the forced vibration.
Therefore, by setting the judgment value of acceleration low,
A warning can be issued early for forced vibration, and the effect of stopping mischief is improved as compared with the conventional example.
