Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a centralized reception device having a system status display function for visually impaired persons, which centrally receives terminals used for key telephone devices, exchanges, and the like.

[0002]

[Prior Art]

 Conventionally, this type of centralized reception device has been provided with local and extension lamps, a visual system status display unit such as an LCD, and a system status display unit for the visually impaired by physically operating parts for the visually impaired. It is equipped with a centralized reception device control unit, and by visually interlocking physical operation parts for the visually impaired in the visual system status display unit, the system usage status can be displayed to the visually impaired. It is configured to be able to.

FIG. 2 shows the configuration of a conventional centralized acceptance device of this type. In FIG. 2, reference numeral 21 is a central control unit including a microcomputer, 22 is a communication control unit including a gate array that controls data communication with the main device, and 23 is a system status display unit visually displayed. , 24 are display drive units for driving the system state display unit 23 by a control signal sent from the central control unit 21, and are composed of a plurality of shift drivers. Reference numeral 25 is a system status display unit for visually impaired persons, which is composed of physical operation parts, and 26 is for driving the system status display unit 25 for visually impaired persons using a signal for driving the system state display unit 23 for vision. Is a data conversion unit of.

Next, the operation of the above conventional example will be described. In FIG. 2, the data of communication between the central control unit 21 and the host control unit of the main unit via the communication control unit 22 indicates the system usage status by the control signal sent from the central control unit 21. The display drive unit 24 drives the system status display unit 23. On the other hand, the drive signal is used to control the system status display unit 25 for the visually impaired. At this time, the data is converted by passing through the data conversion unit 26 to change the display specification.

As described above, even with the above-described conventional centralized reception device, it is possible to display the system state display for the visually-impaired person and the visually-impaired person.

[0006]

[Problems to be solved by the device]

 However, in the above-mentioned conventional method, because the hardware of the data conversion unit 26 changes the specifications for visually impaired persons, it is possible to realize complicated functions, for example, to display a combination of visual display function operations and It is difficult to change the operation specifications to meet the user's request, and the more complicated the function, the higher the cost.

The present invention solves such a conventional problem and is an excellent system status display for visually impaired persons, which is low in cost, high in function, and capable of flexibly responding to user's request. It is intended to provide a centralized reception device having a function.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention controls a display drive unit for driving a physical operation component for a visually impaired person by a central control unit of a centralized reception device, and a software-controlled visual control unit. By directly controlling the specification change setting section for persons with disabilities, it is possible to perform original control while linking with the visual system status display section.

[0009]

[Action]

 Therefore, according to the present invention, it is possible to flexibly meet the specifications of the centralized reception device for the visually impaired, which is required by the user, by setting the program in the specification change setting unit for the visually impaired, which is high at low cost. It has the effect that functions can be realized.

【Example】

 FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 1, reference numeral 11 denotes a central control unit composed of a micro computer, which controls the central reception device by control data from the main device and sends information from the central reception device to the main device. Reference numeral 12 denotes a communication control unit including a gate array that controls communication between the main device and the central control unit 11, and 13 denotes a system status display unit that visually displays the status of the entire system. Reference numeral 14 denotes a display drive unit which drives the system status display unit 13 in response to a control signal sent from the central control unit 11 in response to data from the main device, and is composed of a plurality of shift drivers. Reference numeral 15 is a display drive unit for the visually impaired, which drives the system status display unit 17 for the visually impaired by using the control signal sent from the central control unit 11 to the display drive unit 14 according to the data from the main device. Yes, it consists of multiple shift drivers. Reference numeral 16 denotes a specification change setting unit for the visually impaired who changes the display specifications for the visually impaired according to the user's request. Reference numeral 17 is a system status display unit for the visually impaired, which is composed of physical operation parts for the visually impaired to convey the system status to the visually impaired.

Next, the operation of the above embodiment will be described. In the above-described embodiment, when the data on the usage status of the system is sent from the main unit, the data is sent to the central control unit 11 through the communication control unit 12. As a result, 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 according to the data from the central control unit 11.

On the other hand, the visually impaired display drive unit 15 uses the control output in synchronization with the control signal sent from the central control unit 11 to the display drive unit 14 for the visually impaired system state display unit 17. To drive. At this time, according to the program setting of the specification change setting unit 16 for the visually impaired, how to select and display some kind of display method (LED color, lighting, blinking timing, etc.), for example, red LED It is possible to change to the method selected by the user by, for example, taking the logical product of the operation of the LED and the green LED.

The specification change setting unit 16 for the visually impaired person may be set by software of a host system and the specifications may be changed by control of the host system.

[0014]

[Effect of the device]

 As is apparent from the above-described embodiment, the present invention provides a flexible system status display function for the visually impaired by externally setting a program by directly controlling the visual-impairment specification change setting section by the central control section. It has the advantage of being able to Further, since this control is performed by software, there is an effect that the cost can be reduced while having many functions.
