Abstract

PURPOSE:To simplify a wiring processing by providing a supplying means with a low voltage direct current power source to a telephone set, etc., at a master equipment to connect the telephone set to a telephone line in accordance with the receiving contents from the telephone line and transmit and receive a signal between respective terminals to suffice with only one AC adap. CONSTITUTION:Since the division between jacks 18 and 19 of a master equipment 8 is connected by lead wires 23 and 24 in the internal part, the direct current power source of a low voltage supplied from an AC adapter 11 is supplied from the jack 19 through a power source code 12 to a telephone set 9. Thus, it is not necessary to prepare an another AC adapter as for the telephone set 9, extra expenses are not costly, the system is used by loading the telephone set on the master equipment, the master equipment and the telephone set are made close and arranged, the short power source cord of the telephone set is sufficient, a wiring processing comes to be very simple and a satisfactory external apperance can be obtained.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is a telecontrol system that sends signals from a remote location using a telephone to control equipment such as an F-Fun at home or check its operating status. Regarding the system.

Conventional technology In the past, it was common for telephones to be powered by telephone lines, but in recent years there has been a significant increase in the number of multi-decision telephonists with functions such as name dialing, Increasingly, AC power sources are used as power sources.

Figure 4 shows a schematic diagram of a telecontrol system including the above-mentioned telephone set. In Figure 6, 1 is the parent of the telecontrol system, 2 is the home telephone, and 3 is the string that connects the base unit 1 to the telephone line. , 4 is an AC adapter that supplies low-voltage DC power to the base unit 1, 5 is an AC adapter that supplies low-voltage DC power to the telephone bill 2, 6 is a flap that connects the base unit 1 and the telephone bill 2, and 7 is the base unit 1 This is line 13 for transmitting and receiving control line 15 from the station to each terminal.

<Problems to be Solved by the Invention> The telecontrol system shown in FIG. 4 has the following problems.

(a) Extra costs are incurred because the JJfi telecontrol system and each telephone require an AC adapter.

(1) )? tlW (ii) Line Funcent (Rosenodo, 3 Binjyak, Mononilar Tsuyatsuk h!r
) There is not always an AC power source nearby, and if there is not, 2
I had to carefully route the hood of the AC adapter from the AC power source to the main unit of the telecontrol system.

(c) If the AC power source has 20 outlets,
The telecontrol system alone monopolizes the power, which interferes with the use of other electrical appliances.

The present invention has been made to solve these problems.

Means for solving the problem of communication between terminals and terminals In order to achieve the above object, the telecontrol system of the present invention connects the telephone to the telephone line or connects each terminal depending on the content of the incoming call from the telephone line. The base unit, which sends and receives signals between telephones, is provided with means for supplying low-voltage DC power to telephones and the like.

Function> As mentioned above, in the telecontrol system of the present invention, since low voltage DC power can be supplied from the base unit, AC7C7
It's easy to use, wiring is easy, and AC7
There is no need to monopolize the outlet of the RI source.

<Example> Next, the illustrated embodiment will be specifically described.

The first UA is a schematic diagram of the embodiment, 8 is a base unit of the telecontrol system, 9 is a home telephone 1, 10 is a cord that connects the base unit 8 and a telephone line, 11 is a string, and 11 is a cord that connects the base unit 8. AC adapter that supplies low voltage DC power, 12 is J! A power cord 13 supplies a low-voltage DC power supply from the 8-year-old to the telephone 9, a cord 13 connects the parent 8 and the telephone 9, and 14 is a signal line for transmitting and receiving control signals from the AM8 to each terminal.

Figure 2 is a side view of the above-mentioned JQ Ketsu 8, in which 15 is the upper cabinet, 16 is the lower cabinet, and 17 is Isohimo 1.
Monular jack for 0, 18 is AC7 Gubuta 11
19 is a jack for the plug 12a of the power cord 12, and 20 is a monophonic jack for the cord 13. Shiny 18 for the above plug
and 19 are internally connected as shown in Figure ff13. That is, FIG. 3 is a plan view of the main parts of the main unit 8 with the upper cabinet 15 removed, and 21 and 22 are the terminals of the jack 18 for the plug lla of the AC adapter 11 and the control circuit of the main unit 8. Lead wires 2:l and 24 connect the terminal of the jack 18 and the power supply hood 1 to the board (not shown).
Lead wires 25 and 26 for connecting the terminals of the jack 19 for the second plug 12a are circular holes provided in the side surface of the lower cabinet 16.

In this way, since the jacks 18 and 19 are connected internally, the low voltage DC':ri source supplied from the AC7 adapter 11 is supplied to the telephone bill 9 through the power cord 12 from the jack 19. Therefore, there is no need to prepare a separate AC adapter for the telephone 9.

<Effects of the Invention> As is clear from the explanation of the above embodiments, the present invention has the following effects:
The telecontrol system is equipped with means for supplying low-voltage DC power to telephones and the like. Therefore, (a) Only one AC7 controller is needed, so there is no extra cost.

(b) Using the phone on the base unit, etc.
! By arranging the rock and the telephone close together, the power cord for the telephone bill can be shortened, the wiring becomes extremely simple, and a good appearance can be obtained.

(e) Since only one AC adapter is required, it does not monopolize 20 electrical outlets and does not interfere with the use of electric appliances in the pond.

It has the following advantages and can solve problems during the use of conventional telecontrol systems.
