。The elevator load detection device detects the load in the car,
When the detector reaches a certain specific value, it outputs overload No. 18. This overload No. 16 can be used to activate the safety device, or to compare the number of calls in the elevator car with the number of calls caused by mischief to determine whether the call is 9 or not, and if there are multiple elevators, In order to minimize elevator waiting time, the elevator operation mode is determined, so if an error occurs in the detected amount of load in the car, various problems will occur, and the optimal control of the elevator will be difficult. ■It causes the problem of poor reviews.

＠６から１ａ負荷信号を出υするようにしである。By the way, the conventional elevator load detection device t has a first
As shown in the figure, the negative detector that conventionally uses the in-cage load is
The floor 1 that supports the load inside the car is supported by a spring 2, and the can where the spring 2 is compressed is detected by a pressure detector 43, and the output of this pressure detector 3 is outputted as a comparison signal to the terminal η. [
The comparison signal from 14 is manually inputted to the other terminal of comparator 5, and the comparison fi! Determine the magnitude of the output signal and the output signal of pressure detector 3, and if the output signal is large, compare! Send a signal indicating overload from i5,
This signal is input to the external output signal generating circuit 6, and the load signal 1a is output from this time @6.
しかし、このような従来装置においては、ばね２の圧縮

が発生する。However, in such a conventional device, since the compression state of the spring 2 changes over time, the output from the pressure detector 3, that is, the lateral density changes over time even under the same load conditions. Therefore, even if there is no negative fi (passenger), the pressure detection 43 will output an output, resulting in a difference of 1 in the detected amount. As a result, when the load in the car is not equal to the rated load 1, the 4 external departure signal generation circuit 6 may output an overload [No. 6] indicating that the number of loads exceeds the rated load. .

Comparison means for outputting a signal indicating overload when the output signal is larger than the comparison signal; and correction means for correcting one of the comparison signal and the output signal of the load detector. The point is that the structure is equipped with the following.

。FIG. 2 is a block diagram showing an embodiment of the elevator load detection device of the present invention. The same parts as in FIG. In FIG. 2, a storage device 17 and an adder 8 are newly installed for detection. For example, if the elevator door is closed and the car is not called for a certain period of time, if there are no passengers in the car. Therefore, the output No. 11I (detector) of the pressure detector 3 of the in-car load detector at this time is entered into the detection memory device 7 and stored, and the detection at this time is performed. 1 is an error itself, so next time when a passenger gets into the car with a normal driving warrant, the comparison signal from the comparison signal output fill 14 and the detected contents stored in the storage device 17 are used in the rero Jll device. 8, the 7XI output from the calculator 8 is given as comparison No. 16 corrected to ratio #a5, and this is compared with the output signal of the pressure detection 43.

ものとなる。According to the above-described embodiment of the present invention, the ratio signal given to the comparator 5 is the 1M signal obtained by multiplying the error of the in-car load detector, that is, the error of the output signal of the pressure detector 3 by D0. Therefore, the comparator 5 is equivalent to comparing a normal comparison signal with the accurate output signal of the pressure detection 43, and the overload signal output from the external output signal generation circuit 6 is accurate. .
