[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centralized reception apparatus having a system status display function for visually impaired persons who receives terminals used for a key telephone apparatus, an exchange and the like in a concentrated manner.

[0002]

2. Description of the Related Art Conventionally, a centralized reception apparatus of this type has a central office and an extension lamp, a visual system status display such as an LCD, and a system status for a visually impaired person by physically operating parts for the visually impaired person. The system is provided with a display unit and a centralized reception device control unit. Is configured to be displayed.

FIG. 2 shows the configuration of a conventional centralized reception apparatus of this type. In FIG. 2, reference numeral 21 denotes a central control unit composed of a microcomputer; 22, a communication control unit composed of a gate array that controls data communication with the main device;
Is a system status display section that is visually displayed.
Is a display drive unit that drives the system status display unit 23 according to a control signal sent from the central control unit 21, and is composed of a plurality of shift drivers. Reference numeral 25 denotes a system status display unit for the visually impaired, which is made up of physical operation components. Reference numeral 26 drives the system status display unit 25 for the visually impaired by using a signal for driving the system status display unit 23 for vision. Is a data conversion unit.

Next, the operation of the above conventional example will be described.
In FIG. 2, the central control unit 21 is controlled via the communication control unit 22.
The display drive unit 24 drives the system status display unit 23 according to the control signal sent from the central control unit 21 based on the data communicated between the central control unit 21 and the data communicated between the system control unit and the host system control unit. On the other hand, the system status display unit 25 for the visually impaired is controlled using this drive signal.
In order to change the display specifications, the data is passed through the data conversion unit 26 to perform data conversion.

As described above, even with the above-mentioned conventional centralized reception apparatus, it is possible to display the system status for the visually impaired and the visually impaired.

[0006]

However, in the above-mentioned conventional method, since the specifications of the data conversion unit 26 are changed for the visually impaired by the hardware, complicated functions are realized, for example, visual display function operation. It is difficult to display the combination of the above and to change the operation specifications to meet the demands of individual users, and there is a problem that the cost becomes higher as the function becomes more complicated.

[0007] The present invention solves such a conventional problem, and is an excellent system status display function for the visually impaired, which is low-cost, high-performance, and can flexibly respond to user demands. It is an object of the present invention to provide a centralized reception device provided with the above.

[0008]

According to the present invention, in order to achieve the above object, a central control unit of a centralized reception device controls a display drive unit for driving a physically operating part for a visually impaired person. At the same time, by directly controlling the display specification change setting unit for the visually impaired, which can be controlled by software, independent control is possible while linking with the visual system status display unit.

Therefore, according to the present invention, the visually impaired
Program for the display specification change setting unit for the user can flexibly cope with the specifications of the centralized reception device for the visually impaired user requested by the user, and has the effect of realizing high functions at low cost. Have.

FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. Reference numeral 11 denotes a central control unit composed of a microcomputer, which controls the centralized reception device based on control data from the main device, and sends information from the centralized reception device to the main device. 12 is the main unit and the central control unit 1
Reference numeral 13 denotes a communication state control unit comprising a gate array for controlling communication with the system 1; and 13, a system state display unit for visually displaying the state of the entire system. Reference numeral 14 denotes a display drive unit that drives the system status display unit 13 by a control signal transmitted from the central control unit 11 based on data from the main device, and includes a plurality of shift drivers. Reference numeral 15 denotes a display driver for the visually impaired, which drives a system status display 17 for the visually impaired by using a control signal transmitted from the central controller 11 to the display driver 14 based on data from the main device. Yes, consisting of multiple shift drivers. Reference numeral 16 denotes a display specification change setting unit for the visually impaired for changing the display specification for the visually impaired at the request of the user. Reference numeral 17 denotes a visually-impaired system status display section which is composed of physical operation parts for the visually-impaired person for transmitting the system status to the visually-impaired person.

Next, the operation of the above embodiment will be described.
In the above-described embodiment, when data on the use status of the system is transmitted from the main device, the data is transmitted to the central control unit 11 through the communication control unit 12. Thereby, the central control unit 11 sends a control signal to the display drive unit 14, and
The display drive unit 14 drives each designated display unit of the system status display unit 13 based on data from the central control unit 11.

On the other hand, the display driver 15 for the visually impaired
Drives the system status display unit 17 for the visually impaired by a control output synchronized with a control signal sent from the central control unit 11 to the display drive unit 14. At this time, according to the program setting of the display specification change setting unit 16 for the visually impaired, how to select and display several kinds of display methods (colors of LEDs, lighting, blinking timing, etc.), for example, a red LED AND the operation of the green LED
It can be changed to the method selected by the user.

The display specification change setting section 16 for the visually impaired may be set by software of the upper system and changed by control from the upper system.

[0014]

As is clear from the above embodiment, the present invention directly controls the specification change setting unit for the visually impaired by the central control unit, and displays the system status for the visually impaired by setting the program from the outside. There is an advantage that the function can be made flexible. Further, since this control is performed by software, there is an effect that the cost can be reduced while supporting many functions.
