Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to signal transmission between an elevator control device and operation buttons provided corresponding to service floors.

One way to improve productivity is to unify specifications, reduce the number of models, and increase the number of production units. In order to unify specifications and improve productivity in this way, elevators must be able to cope with changes in the number of floors in a building. Therefore, the conventional approach has been to set the maximum possible service floor as, for example, the 50th floor, and apply control devices with the same specifications to buildings below 50 floors.

By the way, if the service floors are consecutive, the above method can be used, but if the service floors are distributed above and below with a non-service floor in the middle, even if there is a car at the position corresponding to the non-service floor. Because the position indicator must be lit, a control device must be installed in the same way as on the service floor, even though there are no operation buttons on the landing.

Storage device connected to 1, 73, 74, 75, 9
Reference numeral 1 denotes a signal line 92 that connects the control device 1 and the storage device 81 and transmits a reference signal 91a that is at a high level (hereinafter referred to as "H") for one period (including a short delay) of the clock signal 3a. Reference signals 92a to 95 connect the storage devices 82 to 85, respectively, and sequentially become "H" by one period (including a short delay) of the clock signal 3a with a time delay.
~95a (signal 95a not shown), signal lines 101-103... have terminals D connected to signal lines 91-93, respectively, terminal CL connected to signal line 3, and terminal Q connected to signal lines 92-94, respectively. D flip-flop (hereinafter referred to as memory) connected to 11
1 to 113... are D flip-flops (hereinafter referred to as memories) in which the terminal D is connected to the signal line 5, the terminal CL is connected to the terminal Q of the memories 101 to 103..., and the terminal Q is connected to the hall call registration lights 71 to 73..., respectively. , 121-123... are AND gates whose input sides are connected to the signal lines 92-94... and the hall buttons 61-63, respectively, and whose output sides are connected to the signal line 4.

Next, the operation of this conventional example will be explained.

Now, connect clock signal 3a to signal line 3, and connect clock signal 3a to signal line 9.
1, the output 92a of the terminal Q of the memory 101 becomes the input 91a of the terminal D when the input 3a of the terminal CL rises.
2a is a clock signal 3a when the reference signal 91a becomes a low level signal (hereinafter referred to as "L").
It becomes "H" for only one period. Similarly, the reference signals 92a to 94a... sequentially become "H" with a time delay as shown in FIG. Here, the 1st floor (1F)
If the landing button 61 is pressed, when the reference signal 92a becomes "H", the AND gate 12
1 becomes "H" and is transmitted to the control panel 1 on the signal line 4 as a hall call signal 4a. Also, 3
Assuming that the landing button 63 on the 3rd floor is pressed, when the reference signal 94a becomes "H", the output of the AND gate 123 becomes "H", and the same signal line 4
The signal is transmitted as a hall call signal 4a. 1st floor 1
F landing button 61 and 3rd floor 3rd floor landing button 63
Even if the clock signals 3a and 3 are pressed at the same time, the period of the clock signal 3a is extremely short, so that the clock signal 3a is transmitted as a serialized hall call signal 4a on the same signal line 4. By repeating this in order, the states of the hall buttons 61, 63-65 are obtained. When a predetermined number of pulses have been sent as the clock signal 3a, all data is collected. These signals are processed by the control device 1 and registered as hall calls.

Hall call registration signal 5 registered in this way
a is transmitted by the signal line 5, and the input to the terminal D of the memory 112 becomes "H". At this time, the signal 92a, which is the input to the terminal CL of the memory 111, is "H".
Therefore, the output of terminal Q becomes "H" and is maintained. Now, the hall call registration light 72 on the second floor
lights up to indicate that the hall call has been registered. Similarly, the hall call registration light 73 on the third floor is also turned on.

By the way, the landing buttons 61, 63-65 on each floor
The storage device 82 must be installed even though the second floor 2F is a non-service floor because the number of reference signals 91a emitted from the control device 1 is used to determine the signal emitted from the control device 1. figure,
It had the disadvantage of being expensive.

This invention was made in view of the above-mentioned drawbacks, and includes a floor name comparing means for comparing a floor signal in a control device with an actual floor of a building, and a signal is transmitted via this floor name comparing means. By doing so, the purpose is to correspond between the control device and the floors of the actual building, and to eliminate the need to install a storage device even if there is a non-service floor in the middle.

First, in FIG. 4, 1a is an I/O port housed in the control device 1 and connected to signal lines 3 to 5, and 1b is a central processing unit (hereinafter referred to as CPU) that exchanges signals with this I/O port 1a. ), 1c is a read-only memory (hereinafter referred to as ROM) in which the program shown in FIG. 6 is stored, 1d is a readable/writable memory (hereinafter referred to as RAM), and 1e is an I/O
This is a well-known controller that controls the operation of an elevator connected to port 1a.

In FIG. 5, 200 constitutes a part of the ROM 1c, and the number of floors x _i of the building, with 1 being the lowest floor served by the elevator, corresponds to a pointer P consisting of serial numbers from 1 to 50. 211 is a stored floor name comparing means, and 211 is a ROM in which 1 indicating 1F of the 1st floor is stored at the address corresponding to 1 of pointer P;
212 is 3 on the 3rd floor at the address corresponding to 2 of pointer P.
ROM 213 stores 4 of the 4th floor 4F for 3 of pointer P, ROM 214 stores 5 of 5F of 5th floor for 4 of pointer P. It is ROM.

In this embodiment, the 2nd floor 2F is a non-service floor, and the 1st floor 1F to the 5th floor 5F are targeted. Therefore, ROM2 from pointer P=1 to P=4
11 to 214 are used. Since pointers P=5 to P=50 are not used here, they are not set anew. In other words, the initial settings are left as they are. As shown in FIG. 5, the initial settings are "5, 6 to 48, 49, 50" here. 3
00 constitutes a part of the RAM1d, and is a call storage means in which the call signal for each floor is stored in correspondence with the number of floors Xi. 311 with a memory capacity that can store call signals up to 50 floors.

2 is a memory in which a call signal is registered when the second floor 202 is a service floor, 313 to 315 are memories in which call signals for the third floor 203 to fifth floor 205 are stored, respectively, and 316 to 360 are memories in which the call signals for the 6th floor to 50 are respectively stored. This is a memory in which a call signal corresponding to when an elevator services a floor is registered, and is not used in this embodiment.

Next, the operation of the above embodiment will be explained with reference to FIGS. 6 and 7.

FIG. 6 is a flowchart of the program stored in the ROM 1c, and FIG. 7 is a diagram for explaining the operation.

First, when the control device 1 is activated, step 401
In step 402, pointer P is initialized to 1 at time _t0 , and in step 402, clock signal 3a is set to "L" and output to signal line 3 via I/O port 1a. In step 403, the reference signal 91a is set to "H" at time _t1 , and the signal line 9
1 is output. In step 404, floor name comparison means 2
00, the floor number 1 corresponding to the pointer 1 is picked up, and in step 405, if the 1st floor call registration signal is stored in the memory 311 at time _t2 , it is sent to the signal line 5 as the hall call registration signal 5a. Output.

Then, since both the hall call registration signal 5a and the signal 93a of the signal line 93 become "H", a signal is outputted from the memory stored in the storage device 81 and corresponding to the memory 111 shown in FIG. 2 to register the hall call. The light 71 is turned on. By step 406, time t ₃
Then, the clock signal 3a is set to "H" and output to the signal line 3. The reference signal 91a is set to "L" at time _t4 by step 407, and further, step 40
8, the clock signal 3a is set to "L" at time _t5 . As described in the conventional example shown in FIGS. 1 to 3, the signal 93a of the storage device 81 remains at "H". While this signal 93a is "H", the 1st floor 2
When the hall button 61 of 01 is pressed, the signal 4a becomes "H". This signal 4a is
The signal is taken in through the O port 1a, and stored as a first floor call signal in the memory 311 corresponding to the number of floors 1 in step 410. In step 420, pointer P is incremented to 2 at time _t6 , and in step 421, the final value (the final value of pointer P is "the number of floors the elevator stops + 1", which is "5" in this example) ) is checked. Since the pointer P is not yet the final value, the process goes to step 404, and the floor name comparison means 200 is referred to, and the pointer t is
The number of floors 3 is picked up. Step 4
05, memory 3 corresponding to floor number 3 at time t ₇
The third floor call registration signal No. 13 is output to the signal line 5. By step 406, clock signal 3 is activated at time _t8 .
a is set to “H” and output to the signal line 3.
This clock signal 3a causes the signal 94a to go "H" and the signal 92a to go "L". When the landing button 63 on the third floor 203 is pressed when the signal 94a is "H", the signal 4a becomes "H". Pressing the landing buttons 61, 64, and 65 on other floors is invalid. The reference signal 91a is set to "L" in step 407, but since it has already been set to "L" in step 407 when pointer P is 1, there is no change. Clock signal 3 is set at time _t9 by step 408.
a is set to "L". If the landing button 63 on the third floor 3F is pressed while the signal 94a is "H", the signal 4a becomes "H". This signal is taken in through the I/O port 1a in step 409, and in step 41
0 is stored in the memory 313 corresponding to the number of floors 3 as a 3rd floor call signal. The time is determined by step 420.
At _t10 , pointer P is incremented to 3. Similarly, as the pointer P advances from 2 → 3 → 4, the number of floors Xi changes from 3 → 4 → 5,
The reference signal is signal 94a → signal 95a → signal 96a
becomes.

In this way, the 1st floor 1F, the 3rd floor 3F to the 5th floor 5F
The memory devices 81, 83-85 can be activated in sequence to send signals from the hall buttons 61, 63-65 to the control device 1, or to light the hall button registration lights 71, 73-75.

When pointer P is set to "5" in step 420, it is determined to be the final value in step 421, and the process returns to step 401. In step 403, the reference signal 91 is set at time _t19 .
Output a. Below, steps 404~
421 is repeated.

Further, the lighting registration lights 71, 73 to 75 can be turned off in the same manner as described above. In other words, the elevator car is on the 3rd floor.
Suppose that the call signal for the third floor 3F stored in the memory 313 is canceled by the controller 1e. The contents of this memory 313 are output to the signal line 5 between times t ₇ and _{t 11} in FIG. 7 and become "L", and the output of the storage device 83 when the reference signal 94a becomes "H" is ""L" and the registration light 73 goes out.

In addition, in the above embodiment, the landing buttons 61, 63 to
65 and the registration lights 71, 73 to 75 and the control device 1, the present invention is also applicable to the transfer of signals between the destination button on the car operation panel provided in the car and the control device 1. .

In addition, the final value of pointer P is “number of stopping floors +
1", but if the final value of pointer P is checked in step 421 shown in FIG. 6 before incrementing in step 420 and after step 410, the final value of pointer number of beds.

As described above, in this invention, the reference signal is sequentially transferred to each floor in synchronization with the clock pulse signal, and only the signal from the operation button of the floor for which the reference signal is significant is sent to the control device. In the elevator signal transmission device, a floor name comparison means is provided to compare the count value of the clock pulse signal and the floor name where the operation button is installed, and when the signal from the operation button is input to the control device, the floor name comparison means is provided. The floor name comparing means reads the floor name from the count value of the clock pulse signal at that time, and the signal of the operation button is stored in the corresponding memory location based on this floor name. Even if the location includes a floor name, the operation button signal corresponds to the correct floor name by making the above count value correspond to the floor name while excluding non-service floors in the floor name comparison means. This has the effect of being able to be stored in a memory location.
