JPH01212198A - Energy consumption saving system for electronic key telephone system - Google Patents

Abstract

PURPOSE:To reduce energy consumption for the whole title telephone system by stopping the energy consumption concerning the visible and audible displaying of the key telephone set whose key is not operated for a specified time or more at all. CONSTITUTION:When key information does not exist, a key telephone set corresponding counter is checked, whether or not the key telephone set, whose value exceeds the specified value (for example, 2hours=7,200seconds) set beforehand, exists, and an 'energy saving command' is sent through a telephone set interface circuit 2 to the key telephone set concerned. Here, when the 'energy saving command' is received from a main control part 5, a telephone set main control part 14 of the key telephone set concerned makes a visible audible control part 12 into a stopping condition, and even after receiving a visible audible displaying command from a main device based on an existing processing in a following main processing and interrupting processing, by stopping the visible and audible displaying control part 12, the control part is made into an energy saved condition. Thus, the energy consumption can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electronic button telephone device comprising a plurality of button telephones and a main device.

(Conventional technology) Electronic button telephone devices are widespread.

Conventionally, this type of button telephone device has been designed to reduce the power consumption of the connected button telephone.(Problem to be Solved by the Invention) , the visual indicators (LED and L
CD) and an audible display (ring tone from a speaker or BGM) are always in operation, which has the disadvantage that the power consumption of the entire button telephone device is large, which hinders the efficient power consumption of the button telephone device. .

The object of the present invention is to overcome the above-mentioned drawbacks.

An object of the present invention is to provide a power-saving method for a nine-den ten-key button telephone device that reduces power consumption.

(Means for Solving the Problems) In order to achieve the above object, the power saving method of the electronic button telephone device according to the present invention includes a control unit for controlling visual and audible displays, and a key input on the operation surface of the button telephone. A plurality of button telephones each having a key input detection section for detecting the key input detection section and a telephone main control section for controlling these, a power supply machine interface circuit for connecting the plurality of button telephones, a code section for storing a program, and a button telephone. In an electronic button telephone device comprising a main device having a data section for storing various service information etc. in the device and a main control section for controlling the valley section, the data section in the main device is provided with information corresponding to each button telephone. A counter is provided in the main control unit, and the main control unit in the main device is provided with a control means for incrementing the counter by interrupt processing at fixed time intervals, and a control means for incrementing the counter by interrupt processing at regular intervals. Clears the counter corresponding to the pressed button telephone, and sends a 1i11L command money to remove the power saving tile to the button telephone that is in the power saving state.If there is no key input information, clears the counter corresponding to the button telephone whose counter value has reached the specified value. A control means is provided for transmitting a power saving command to the button telephone, and a control means for operating/stopping the button telephone 1735 visual/audible control section in response to a power saving command is provided in the telephone main control section of the key telephone. The present invention is configured to stop displaying information on a button telephone that is not operated.

(Example) Hereinafter, the present invention will be explained in more detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an electronic key telephone device according to the present invention.

Inside the main device 1 is a telephone interface circuit 2 connected to a key telephone. It is composed of a data section 3 that stores various data such as service information within the device, a code section 4 that stores a program for the main control section, and a main control section 5 that controls these.

11, inside the button telephone 11, there is a viewing control section 12 that controls the visual and audible display on the button telephone, a key input detection section 13 that detects each key input by button operation on the button telephone, and these components. It is composed of a key telephone main control section 14 that stores all control programs and data.

FIG. 2 is a diagram for explaining the main processing and interrupt processing procedures of the key telephone device.

The main control unit 5 increments (by one) the area corresponding to all the button telephones in the button telephone corresponding counter in the data section 3 by an interrupt process executed at regular intervals (for example, every second). count up) (Figure 2 Step 2)
1).

- In the main control unit main processing, when a button operation (for example, off-hook or dial press) is performed on a certain button telephone, the "key information" sent through the telephone interface circuit 2 is checked. Action (Step 22)
), if key information is present, initialize the counter value of the button telephone counter of the corresponding button telephone (step 23).
).

fc, if there is no key information, check the key telephone counter and determine whether there is a key telephone that has exceeded a predetermined limit t (for example, 2 hours - "7200" seconds) (procedure). 24), sends "1 power saving command" to the corresponding button telephone via the telephone interface circuit 2 (step 25).

Here, the telephone main control unit 14 in the corresponding button telephone,
When receiving the 9 power saving command nlr from the main control unit 5, the visual and audible control unit 12 is stopped, and a visual and audible display command is issued from the main device based on the existing processing (step 27) in the subsequent main processing and interrupt processing. As a precaution, the visual and audible display control section 12 is stopped to enter a power saving state in which -bright display is not performed.

Here, if any key input is made on the corresponding button telephone, the key input detection section 13 sends the main key input information to the telephone main control section 14, and the telephone main control section 14 sends this information to the telephone interface circuit 2. via the main control unit 5
Send to.

The main control unit 5 initializes the area of the corresponding button telephone in the key telephone compatible counter, and sends a "power saving command" indicating cancellation of power saving to the corresponding key telephone main control unit 14 (step 26).Push button telephone The main control unit 14 restores the visual and audible control unit 12 from the stopped state in response to this "cancellation" power saving command and brings it into the operating state.

(Effects of the Invention) As explained above, the present invention has the advantage that -
Since it is configured to stop the power consumption related to the viewing display of key telephones that do not have the off button operated, it is possible to provide the normal service functions for key telephones that are frequently used. This has the effect of reducing the power consumption of a telephone with a low number of buttons, and making it possible to efficiently consume power of the entire system.
