Abstract

PURPOSE:To obtain excellent usability by switchingly selecting a cipher type elevator operation and an ordinary elevator operation and switching over to the ordinary elevator operation when the elevator is used by an ordinary person. CONSTITUTION:As a selecting switch 22 is set to a cipher side, a normally open contact 22a is closed and the command signal of a cipher type operation is turned on and inputted through a receiver 15. Here, if a full automatic operation is adopted, the cipher type operation with which the calling register of a specific floor is unable unless a cipher is inputted is adopted and the indicating lamp of during cipher operation is lit for indication. Then, as the switch 22 is set to an ordinary side, both of normally open contacts 22a, 22b are closed, turning off the command signal of the cipher type operation. Thereby, the cipher type operation is stopped switching over to an ordinary operation, turning off the indicating lamp of the during cipher operation. Therefore, the secrecy of the cipher type operation can be kept from ordinary persons to be effective to a crime preventing operation, while enabling the ordinary person to get rid of carrying out the troublesome cipher type operation.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an improvement in a so-called encrypted call registration device for limiting the number of people who can register a call for a specific floor of an elevator.

[Conventional technology]

Normal elevators can be used freely by an unspecified number of people. However, for crime prevention and privacy protection, the number of people using elevators is limited on certain floors, such as the executive power level, computer power level, and the so-called Getabaki Pill residential level, where the lower part is the store and the upper part is the residence. There is a need. For this reason, in the past, a key switch was used to call a specific floor instead of a normal push button, but carrying a key switch was a hassle.
There was a drawback that if you forgot, you would not be able to use the elevator. Therefore, JP-A-55-66468 and JP-A-59-
98474, a car call or hall call for a specific floor can be registered only when the code code is input by operating the push buttons in the elevator car or at the hall in a special manner, such as by operating the push buttons in the elevator car or at the hall. I try to do that. These operations are described in the above-mentioned patent publication, so explanations are omitted, but in both cases, even if the call button for a specific floor is operated, the call is not registered, and the button is pressed according to a preset code code. The call for a specific floor is registered only when the button is operated. In the above-mentioned patent publication, the encrypted call registration device is constructed from a relay circuit, but in recent years it has been constructed from a microcomputer program. In addition, in consideration of the case where the board room policy is changed or the code code is discovered, the administrator etc. can freely set or change the specific floor and code code mentioned above.

[Problem to be solved by the invention]

Conventional encrypted call registration devices are configured as described above, so call registration for a specific floor is always encrypted and can be done within seconds.
- There is a drawback that outpatients, newspaper delivery people, etc. cannot use the elevator. Here, if you teach the code to a foreign visitor or newspaper delivery person, they can use the elevator, but you cannot tell them because the code would be meaningless. Additionally, during times when many people use elevators, such as when commuting to and from work, there is less need for crime prevention and privacy protection, and the problem is that it takes time to operate the code, and that the code may be revealed to other passengers in the car. was there. This invention was made to solve the above-mentioned problems. - A code that allows out-of-office visitors, newspaper delivery workers, etc. to use the elevator, and also saves them the trouble of operating codes when coming to and leaving work. The object of the present invention is to obtain a system call registration device and to enable a building manager or the like to easily determine whether or not the building is operating using a code.

[Means to solve the problem]

The elevator control device according to the present invention registers a call for a specific floor by pressing the push buttons in a specific order and registering a call for a specific floor by pressing the push buttons in a specific order when registering the call. In addition, the system is equipped with a function to switch and select each call registration, and to display the call registration method in operation.

[For production]

According to this invention, during times when there are many elevator users, the call registration button for the destination floor is registered by pressing the call registration button in the usual manner. When registering a call to a specific floor, press the normal call registration buttons in a specific order,
Since call registration can only be performed after entering a password, it is possible to easily switch from normal operation to crime prevention operation by switching between each call registration method.

【Example】

An embodiment of the present invention will be described below. In Figure 1, 1 is a block diagram of a control device in a control panel installed in a machine room, 2 is a block diagram of an operation panel installed in a manager's room, etc., and 11 is a block diagram of a control device installed in a control panel installed in a manager's room, etc. A central processing unit CPU, 12 a read-only memory ROM that stores programs, 13 a read/write memory RAM for primary hourly calculation results, 14 a drive device driver for outputting signals to external equipment such as lamps, and 15 a read-only memory ROM that stores programs; A voltage converter receiver for inputting signals from switches and buttons of external devices, 16 an internal signal bus such as an address bus and data path, 21 an encrypted operation indicator light, 22a a selection switch 22, 22b is a normally open contact that closes when the selection switch 22 is set to the automatic side; 22c is a normally open contact for a timer switch (not shown) that closes only during a specific time period. be. FIG. 2 is an external view of an operation panel installed in a manager's room, etc., where 2a is an operation panel, 21 is a coded operation indicator light, and 22 is a selection switch. FIG. 3 is a flowchart 1 showing the procedure for the selected part of the cryptographic operation in the program of the ROM 12. First, the operation of selecting encrypted driving will be explained. When the selection switch 22 shown in FIG. 2 is set to the encryption side, the normally open contact 22a shown in FIG. Here, if fully automatic operation is used, procedure 3 in the flowchart in Figure 3
1 becomes YES and goes to procedure 32. Since the command signal for encrypted operation has been input, procedure 32 also becomes YES and the process goes to procedure 33. If there is a floor for which a code has been set, procedure 33 will also be YES and the process will proceed to procedure 34. In step 34, the system switches to encrypted operation in which call registration is not possible without entering a code on a specific floor, and lights up the encrypted operation indicator light to display the code. Next, we will explain the operation of selecting normal operation for guests, newspaper delivery people, etc. When the selection switch 22 shown in FIG. 2 is set to the normal side, both normally open contacts 22a and 22b shown in FIG. 1 are opened, so that the command signal for cryptographic operation is turned off. Therefore, procedure 3 in Figure 3
2 is NO, and the process goes to procedure 35. In procedure 35, the encrypted operation is stopped, switched to normal operation, and the indicator light during encrypted operation is turned off. Note that when the selection switch 22 in FIG. 2 is set to the automatic side, the first
The normally open contact 21a shown in the figure opens, and the normally open contact 21b closes. Therefore, if a timer switch (not shown) is used to open the normally open contact 22c in FIG. 1 only during work hours and when the newspaper delivery person arrives, the manager or the like can select between encrypted mode and normal mode using the selection switch. There is no need to switch. In addition, in the case of manual operation for maintenance or operation with a driver, procedure 31 in FIG. 3 will be No, and encrypted operation will not be performed. Therefore, maintenance of the elevator can be carried out without teaching the code to maintenance personnel and the like, making it difficult for the code to be discovered. Also, if the selection switch 22 in FIG. 2 fails, the procedure 32 in FIG.
If you accidentally reset all the codes and forget about it (or procedure 33 in Figure 3 will be NO. Therefore,
In either case, the indicator light does not light up during encrypted operation, so if there is a malfunction or abnormality, it can be detected early in the morning. [Effects of the Invention] As described above, according to the present invention, it is possible to switch between encrypted elevator operation and normal elevator operation using a selection switch, etc., and - when the largest number of people use the elevator. Since the system switches to normal elevator operation, the secrecy of encrypted operation from the general public is maintained, which is effective for crime prevention, and the elevator is easy to use because the general public does not need to perform cumbersome encrypted operation operations. It is effective in providing the following.
