Abstract

PURPOSE:To efficiently use the batteries of all slave sets by providing a designat ed telephone set connected to a key telephone main device and setting the battery saving period of the slave set for each hand set for the unit of time. CONSTITUTION:The designated telephone set connected to a main device 20 daily sets the several patterns of battery saving periods every one hour for each slave set 40 and stores them in a memory 21. This stored period pattern number for each salve set is sent through a CPU 25, an I/F part 23, an I/F part 31 of a master set 30, a microcomputer 38, a MODEM 36, an RF circuit 34, an antenna 35, an antenna 41 of the slave set 40, an RF circuit 42 and a MODEM 48 to a microcomputer 411, stored in a memory 49 and managed. At the time of waiting, the slave set 40 performs the ON/ OFF power source control corresponding to the period pattern number stored in the memory 49. Thus, the designated telephone set can set the battery saving period for each slave set for the unit of time corresponding to the frequency of using each slave set, and the batteries of all the slave sets can be efficiently used.

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system cordless telephone device which saves battery consumption of a handset.

2. Description of the Related Art First, an outline of the configuration of a system cordless telephone device will be described. This system cordless is added to the key telephone main unit by an add-on method and can be mixed with a wired general telephone. The master unit is connected to the main unit by wire and performs the same data communication as a key telephone, and is installed at an appropriate place on the premises to form a wireless zone. The master unit performs connection control and call holding, but one master unit can hold only one slave unit.
If you need to make simultaneous calls in the same area, install multiple base units as a base unit group. Therefore, when there are a plurality of areas, a plurality of parent device groups are installed in each area. A plurality of handset units are prepared according to the number of base units, and are installed in the premises in the same manner as general extension telephones. Since each is a low-power cordless telephone, it can be moved within a line-of-sight range of up to about 100 m and can be connected to any base unit. Next, a conventional system cordless telephone device will be described. The key telephone main unit sets the battery saving cycle of the handset so that it can use the battery efficiently by lengthening the time with the designated telephone whose power is off during periods of low traffic of the handset. . However, all slave units are set with the same periodic pattern. As a setting example, FIG. 5 shows the periodic pattern number for each time, and FIG. 6 shows the state of the power on / off time for each periodic pattern number.

However, in the above-mentioned conventional system cordless telephone device, the battery saving cycle of the slave units is the same pattern in all the slave units, although the frequency of use in units of time is different for each slave unit. Since it is set, there is a problem that the batteries of all the slaves cannot be used efficiently. The present invention solves such a conventional problem, and an object of the present invention is to provide an excellent system cordless telephone device in which a battery can be efficiently used in all handsets.

In order to achieve the above object, the present invention has at least one master unit connected to a key telephone main unit and at least one slave unit wirelessly connected to the master unit. A system cordless telephone device having a telephone set is provided with a designated telephone which is connected to the key telephone main unit and sets the battery saving cycle of the handset for each handset on an hourly basis.

Therefore, according to the present invention, the battery saving cycle can be set for each slave unit in units of time according to the frequency of use of each slave unit by the designated telephone.

1 and 2 show the structure of an embodiment of the present invention. In FIGS. 1 and 2, reference numeral 10 denotes a system cordless telephone device, which includes a main device 20, a plurality of master devices 30 connected to the main device 20 by wire, and a plurality of slave devices that can be wirelessly connected to the master device 30. 40 is provided. In the main unit 20, 21 is a memory for storing a battery saving cycle of each hour unit for each slave unit, 22 is an interface circuit for detecting incoming line, forming a call, dialing out, etc. 23 is a master unit 30 and A telephone interface unit for controlling data communication with other telephones, 24 is a service tone generator unit for various tones, 25 is a unit for managing and controlling each unit of the main device 20, and each master unit 30 and each slave unit 4
It is a CPU that performs management control including 0 position registration. In the parent device 30, 31 is an interface unit for wired data communication with the main device 20, 32 is a codec connected to the interface unit 31 for analog / digital conversion, 33 is a call circuit connected to the codec 32, Reference numeral 34 is an RF circuit connected to the call circuit 33, 35 is an antenna connected to the RF circuit 34 for transmitting and receiving radio waves, 36 is a modem, 37 is an ID ROM, and 38 is the base unit 3.
0 Each unit is managed and controlled, and wired communication control with the main device 20 and wireless communication control with the slave device 40 are performed. In the child device 40, 41 is an antenna for transmitting and receiving radio waves, 42 is an RF circuit connected to the antenna 41, 4
3 is a call circuit connected to the RF circuit 42, 44 is a call circuit 43 connected to the call circuit 43, and a transmitting / receiving section 44, 45 for listening to and talking a voice, a display section for displaying the current time and the telephone number of the other party, and 46 are Buzzer that sounds a ring tone, 47 is a dial key equipped with dial buttons, 48 is a modem,
49 is an ID ROM, 410 is a battery, and 411 is a child device 40.
It manages and controls each unit, and controls data communication with the master device 30. A designated telephone 50 is connected to the main device 20, a function selected according to the user's needs is selected, and a battery saving cycle of each slave 40 is set for each time unit. Next, the operation of the above embodiment will be described. Designated telephone 50, 1 for each cordless handset 40 per day
Several patterns of battery saving cycles are set for each hour and stored in the memory 21 of the main device 20. FIG. 3 shows an example of setting the periodic pattern number for each hour. The power on / off time of the periodic pattern number is the same as in FIG. 6 shown in the conventional example. In FIG. 3, in the cycle type 1, the power-off time is long from 20:00 to 8:00, the power-off time is short from 10:00 to 15:00, and from 15:00 to 20:00, the standard is set in three stages in between. This is a typical example. The cycle type 2 is an example of emphasis on nighttime when the frequency of use of the handset 40 is high at night, such as a short power-off time from 17:00 to 8:00 and an intermediate time from 8:00 to 17:00. In the cycle type 3, when the power off time is short from 12:00 to 20:00, the off time is long from 0:00 to 7:00, and the remaining time is in the middle of the time, and when the handset 40 is frequently used in the afternoon. This is an example of emphasis on the afternoon. Which child machine 4
