Abstract

PURPOSE:To eliminate a feeling of uncomfortableness to passengers by automatically raising the judgment level of erroneous call input when the frequency of detecting more than a determined number of call signals within a determined time is high, and making the call input within the determined time up to the determined number as a normal input. CONSTITUTION:A call signal registered in a master station 9 is sent to a judgment circuit 10, wherein the presence of more than a preliminarily set determined number of calls within a determined time is judged. When the call frequency is more than the determined number, the calls more than the determined number are counted by a counter 11, and according to the judgment frequency, the set determined number is increased by a determined number setting circuit 12. Thus, when the frequency of detections of more than the determined number of call signals within a determined time is high, the judgment level of erroneous call input is automatically raised, so that the call input within the determined time up to the determined number is made as normal call input, and a feeling of dissatisfaction to passengers is reduced.

This will be displayed on the hall call registration light installed at the station. Furthermore, the car call registration signal is transmitted by operating the call button (6) provided at the remote station (3) in the car, and the completion of car call registration is completed by operating the car call button (6) provided at the remote station (3).

Next, the operation of the conventional device having the above configuration will be explained with reference to FIGS. 5 to 8. FIG. 5 is a timing chart showing signal input/output between the control microcomputer (1) and each remote station R5I to R58, divided into time cycles (TI) to (T6).

On the other hand, the call signal data inputted by the control microcomputer (1) is transmitted to remote stations R53 and R56.
The signal levels of 2 bits and 5 bits corresponding to 2 and 5 bits are low level indicating that there is a call.

Also, in the above time chart, calls that occur at each remote station (R5I to R11) during T are called at T4.

Alternatively, if the counter value of counter 1 is not equal to or greater than the predetermined number, the number of data bits of the call signal data that is the call signal input from each remote station is counted, and counter 2 is incremented by 1 (process 406). Check whether this counting result matches the set number of call input data pits (see Figure 6 (a)), which is the call signal input from all remote stations, and if the result is less than or equal to the number of input data pits. If it is determined that this is the case, the process returns to step 401 to further check input data pits from remote stations on other floors. If the check in process (407) determines that the two counter values are equal to the number of call input data, process 408) to initialize counter 2;
Proceeding to (process 600), the determined call data is registered in the main station.

[Problem to be solved by the invention]

A conventional elevator signal transmission device is configured as described above, and when a predetermined number or more call inputs are received within a predetermined time, this is determined to be an erroneous call input and canceled. However, no countermeasures have been taken for cases where the number of calls is large enough to be judged as an incorrect call input, and in reality, even though the caller force that occurs frequently is a legitimate caller force, it is canceled out as an incorrect call input. There are cases where the call is not registered as a call input, causing discomfort to passengers.

This invention was made in order to solve the above-mentioned problems, and it is a system in which when the number of call inputs is more than a predetermined number within a predetermined time, it is not uniquely canceled out as an erroneous call input. The purpose is to obtain an elevator signal transmission device.

(Means for Solving the Problems) An elevator signal transmission device according to the present invention is provided at a main station for signal transmission provided in the main control panel of the elevator, an operation panel on each landing floor, and an in-car operation panel. In addition to placing a signal transmission line between the remote stations for transmitting the missed signal, the main station is set to the number of times the call registration signal occurs within a certain period of time, which is a guideline for determining whether there is an incorrect call registration. A determination circuit that determines whether a call registration signal has been transmitted more than a set number of times, a counter that counts the number of times the call registration signal has been transmitted, and a counter that counts the number of times the call registration signal has been transmitted. A number setting circuit for increasing the call registration signal determination level is provided.

[Effect]

The elevator signal transmission device according to the present invention automatically raises the determination level for false call input when a predetermined number or more call signals are detected within a predetermined time, and Call inputs within the specified time are treated as regular call inputs.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
The figure shows the control microcomputer (1) in this embodiment.
It is an internal block diagram of (a). In the figure, (9) is a master station that registers calls, (10) is a determination circuit that determines that there are more than a preset number of calls in a predetermined time, and (11) is the number of calls that are determined to be more than this predetermined number. The counter (12) is a predetermined number setting circuit that increases the predetermined set number according to the number of times of determination by the counter (11).

Incidentally, the overall configuration diagram of the signal transmission device is the same as that shown in FIG.

Next, based on the above configuration, the operation of this embodiment will be explained according to the flowchart shown in FIG. This flowchart includes a detailed operation flowchart when the process (400) shown in FIG. 7 is implemented in this embodiment, and other processes (1
00) to (300), (500).

(aOO) is the same as in the prior art. First, the transmission line (8
), the manually input call signal data is shifted to the left by 1 bit, and it is determined whether the carry flag is '0'', that is, the bit signal level is Low, and whether there is a call signal data (process 401), (IA 402).

If this carry flag is "0", the number of call inputs is counted by incrementing the number of call inputs by incrementing the number of call inputs 403)), and whether or not this count value is greater than or equal to a preset predetermined number. is determined (process 404).

At this time, the process (400) has already been repeated several times,

), and further initializes counter 2 (process 414), and then increments counter 3, which counts the number of times a predetermined number or more of call inputs have occurred during the IT cycle (
Processing 409). Thereafter, it is determined whether the counter value 3 is greater than or equal to the predetermined number (41Q), and if it is not greater than the predetermined number, it is treated as a frequent occurrence of caller force due to noise on the signal line (SOO) (see Figure 7). and do not register it in the main station as erroneous call data.

Further, as a result of incrementing the counter 3, if it is determined that the counter value 3 is greater than or equal to the predetermined number, then within the predetermined time (I
Add 1 to a predetermined number that determines the allowable number of call inputs in T cycle) and update it (411), then counter 3
is initialized (processing 412). And this calling power...
is not registered in the main station as incorrect data (process 500).

Also, if the carry (≠O) or call input is not read in the above process (402), or if the counter value 1 does not exceed the predetermined number in the process (404), that is, if the call is not read within one cycle. When manual labor is not required frequently, a counter 2 that counts the number of times the call input data is read is incremented (process 406). The counter value 2 is the total call input data (
Call input from each floor) Process to determine whether it is equal to a 4
07) If all call input data has not been read, processes (401) to (407) are executed again. If call inputs do not occur abnormally frequently and all call input data has been read (process 407), counter 2 and counter 1
The process proceeds to initialization (process 408.413.600) and the read caller power data is registered in the main station.

Next, call data is inputted through the transmission line again in Tl+n cycles (process 300).

(Effects of the Invention) As described above, according to the present invention, when a predetermined number or more call registration signals that are determined to be erroneous call registration signals occur frequently within a predetermined time, the number of occurrences is counted and Once the number of call registration signals has been counted, the predetermined number is increased to raise the judgment level of the false call registration signal. Since it is registered as a call input, it has the effect of increasing the transmission reliability of the call registration signal without causing discomfort to passengers.
