JPH0846706A - Dialing restriction system for lobby doorphone device - Google Patents

Abstract

PURPOSE:To reduce man-hours of error check relating to the input of restriction information by restricting dialing by means of part of digits of a call number so as to suppress restriction to be stored for dialing restriction. CONSTITUTION:When a call number '1023' is depressed by a call dial 10 of a lobby doorphone device 1, a number is sent to a memory 11 and stored therein for each depression of the call dial 10. The call number, '1023' stored in the memory 11 is given to a transmitter 14. A restricted digit value '0' stored in an address in the memory 11 designated by a signal of a restricted digit from a memory 12 is outputted to a comparator 13. The comparator 13 compares a signal of a restricted value '5' received from the memory 12 with the restricted digit value '0' and gives a level 1 to the transmitter 14 as a comparison signal 20 when they are coincident. When dissident, '0' is given to the transmitter 14 as the comparison signal 20. The transmitter 14 dials the signal '1023' received from the memory 11 when the value of the comparison signal 20 is '1'.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lobby intercom system, and more particularly to a transmission restriction system thereof.

[0002]

2. Description of the Related Art A conventional lobby intercom system is constructed to register a callable dwelling unit number in a storage means. With such a configuration, the lobby intercom device searches the dwelling unit number registered in the storage means with the entered dwelling unit number by pressing the dwelling unit number and the call button, and if the dwelling unit number is found, the calling is permitted. Was working like.

[0003]

Therefore, when the outgoing call is restricted by the conventional technique, it is necessary to register a callable dwelling unit number for each lobby intercom device, which causes a problem that a great number of man-hours are required to check an input error. there were.

Further, when calling a dwelling unit number that cannot be called, since the dwelling unit number and related information are not stored, there is a problem that the lobby doorphone device that can access the calling dwelling unit number and guidance display such as an access route cannot be displayed. An object of the present invention is to solve such a problem and reduce the number of inputs required for data input for transmission restriction. A further object of the present invention is to provide a lobby intercom device that allows access to a calling house number and a guidance display such as an access route.

[0005]

In order to achieve such an object, the present invention is configured to store a restriction digit for restricting a calling number and a restriction value of the restriction digit in a storage means. The present invention is further configured to store the guidance such as an access route and a lobby doorphone device that can access the calling dwelling unit number in correspondence with the regulation value of the calling number of another lobby doorphone device in the storage means.

[0006]

The lobby door intercom device operates so as to compare the value of the control digit of the input dwelling unit number with the control value and, if they do not match, control the call and do not call. Furthermore, when the value of the regulation digit of the input dwelling unit number does not match the regulation value, the lobby intercom device operates so as to notify the guidance corresponding to the value of the regulation digit.

[0007]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a block diagram of an embodiment of a transmission control means of a lobby door phone device, in which 1 is a lobby door phone device, 10 is a calling dial, 11 and 12 are memories, 1
3 is a comparator, 14 is a transmitter, and 20 is a comparison signal.

When the call number "1023" is pressed by the call dial 10 of the lobby door phone device 1, the number is sent to the memory 11 and stored every time the number of the call dial 10 is pressed.

When the calling of the calling dial 10 is pressed, the memory 11 stores the stored calling number [1023].
Is input to the transmitting device 14. Further, the memory 11 outputs the value “0” of the regulation digit accumulated from the memory 12 at the location addressed by the signal of the regulation digit “2” to the comparator 13.

The comparator 13 compares the signal of the regulation value "5" input from the memory 12 with the regulation digit value "0", and when they coincide with each other, sets 1 as the comparison signal 20.
Enter in 4.

If they do not match, the comparison signal 20 is 0.
Is input to the transmitting device 14. When the value of the comparison signal 20 is 1, the transmission device 14 makes a dial transmission using the calling number “1023” input from the memory 11.

As is clear from the above description, transmission control can be performed by using the digits and values of the call number to be regulated as information. In the above description, the memory 12 is used as the storage means, but transmission restriction can be made even if 12 is replaced with a disk device.

Further, although the case of one restricting digit has been described, a plurality of restricting digits can be provided by using a plurality of comparators. Further, the comparison signal is transmitted at 1, but can be transmitted at 0.

FIG. 2 is a block diagram of an embodiment of the guidance display means of the lobby intercom system. 1 is a lobby intercom system, 10 is a calling dial, 11 and 12 are memories, 13 is a comparator, 20 is a comparison signal, Reference numeral 15 is a display control circuit, 16 is a display device, 21 is guidance, and 22 is a guidance signal.

When the calling number "1023" is pressed by the calling dial 10 of the lobby intercom system 1, each time the number of the calling dial 10 is pressed, the number is sent to and stored in the memory 11.

When the calling of the calling dial 10 is pressed, the memory 11 outputs to the comparator 13 the value "0" of the regulation digit stored in the location addressed by the signal of the regulation digit "2" from the memory 12. To do.

The comparator 13 compares the signal of the regulation value "5" input from the memory 12 with the value of the regulation digit "0", and when they match, inputs 1 as the comparison signal 20 to the display control circuit 15.

If they do not match, the comparison signal 20 is set to 0.
Is input to the display control circuit 15. The display control circuit 15 is
When the comparison signal 21 is "0", the memory 12 is searched with the value "0" of the regulation digit input from the memory 11, and the display value "guidance 1" corresponding to the regulation value "0" is taken out as the guidance 21. The extracted guidance is input to the display device 16 as a guidance signal 22.

The display device 16 displays the input guidance. As is clear from the above description, the guidance accumulated in the lobby door intercom device can be searched and displayed by the digits of the call restriction and the restriction value.

Further, it is possible to set a plurality of display values. In the above description, the display control circuit 15 and the display device 16 are described.
It is possible to notify the guidance by using 6 as a voice synthesizer or a voice output device.

[0021]

As described above, according to the present invention,
Since the call is restricted by the value of a part of the calling number, the restriction information accumulated for restricting the call can be suppressed.
As a result, there is an advantage that the number of man-hours such as an error and a check related to the input of the regulation information can be significantly reduced.

Further, since the guidance is stored in combination with the regulation value, it becomes possible to notify the user of the guidance for the numbers not called. This has the advantage that the user can know the next action or operation method.
