Abstract

PURPOSE:To control a power supply for a load in a home or the like from a telephone set placed at a remote location easily by providing a control means which performs incoming control, data receiving control, signal response control and output device control by comparing and collating a receiving data and a switch setting data. CONSTITUTION:A 16Hz call signal from a line rings a telephone set 4 through a sectioning device 8 and it is detected at a call signal detecting section 9 after several seconds. The detected signal sets a latch circuit 10, the latch output operates a line connecting relay 11 to change over its contact 11a and the telephone set attains the incoming state and the ring of the telephone set 14 is stopped. On the other hand, the latch output is displayed on a display section 14 for incoming call and inputted to a CPU19 through an input/output interface 18 as an incoming signal. The CPU19 outputs an incoming response signal to a decoder 16 via the input/output interface 18, the output of the decoder operates a response oscillating circuit 15 and outputs a response tone to the line through a relay contact 17a, a closing coil 18 and a relay contact 11a.

After calling a home etc. through the exchange (3) in b), a +- code and a control signal are sent from the PB signal transmitter (2) connected to the mouthpiece of the telephone (1a) or (1b). The telephone (4) in the house rings, the telephone controller (5) detects the ringing signal, receives and decodes the FB double signal, processes the data in the CPU, and connects the power switch (6a) (6b).
are operated respectively to control the power source loads (7a) and (7b).

Figure 2 is a circuit block diagram of the T-talk controller (5).
(8) is a disconnector, (9) is a call signal detection unit, (11 is a latch circuit, 01) is a line connection relay % o2 is a DC closing coil, 0.1 is a PR receiver, q→ is a display unit , OQ is a response sound oscillation circuit, (Ifl is a data), (171 is a transmission/reception switching relay b (1?a) is its contact, 0 is an input/output interface, and o9 is a central processing unit (hereinafter referred to as CPU). ), (4) are met, e2D is the switch setting section, 翰 is the relay control section, (c) ■ is the output control relay, (2a
a) (24a) is the contact point, and (a) the wire is the monitoring port.

A calling signal (16 field signal) from the line causes the telephone set (4) to ring through the disconnector (8), and is detected several seconds later by the calling signal detecting section (9). The detection signal sets the latch circuit 01, and the 1 latch output is the line connection relay (11)
is activated to switch its contact (lla), a DC loop is formed in the DC closing coil a2, and the telephone f+4) stops ringing when a call is received. On the other hand, the latch output displays an incoming call on the display section G41, and is input as an incoming call signal to the CPU H through the input/output interface (1 frame. Activate it, output the incoming call response signal to Jiko'2 ttti through the input/output interface frame 0, operate the responder oscillation circuit (to) at the equalizer output, relay contact (17a), closing coil (to), relay Contact (tX
A response tone is output to the line through a). A part of the incoming call response signal is output to display section 0 to display a response.

In addition, the CPU OQ immediately outputs a transmission/reception switching signal after outputting the incoming call response signal to activate the transmission/reception switching relay 0η.
Switch the contact (17a) to the receiving side. After receiving the response tone, the calling phone converts the receiver code and the control signal of the load to be controlled (load power on/off, etc.) into a PB signal and sends it out, and the signal is sent to the telephone controller (5). PR
Received and decoded by the receiver 03, the timing signal,
It is input to the CPU (1'J) through the input/output interface (to) as a 4-way signal.CPU 0
0 stores the received ETA in the data buffer of the memory and checks the ETA with the ETA preset in the switch setting section Q1). Only when the operator code and control signal match, relay control is performed. The output control relay (c) is actuated through the part υ, the relay contact (28a) or (24a) is closed, and the connected power switch (6a) or (6b) is actuated.
The power to the load is controlled (on or off). CPU
flee monitors the operation of the power switch (6a) or (6b) through the monitoring boat (a) or (b),
Check the contact information of the power switches (6a) (6b), and check that the contacts of the power switches (6a) (6b) are closed, for example, if the control signal is on the load heavy source. , and then outputs an ACK response signal to the Pukor 40 to operate the response sound oscillation circuit 0υ.

At the same time, switch the transmission/reception switching relay 0'h to the transmission upper mode,
A response tone is output to the line and the relay (171) is returned to its original state. If the next control signal is not received within a certain period of time, c
rtJnts outputs a line release signal to reset the latch circuit plane, return the line connection relay OB, and release the line. In addition to the above-mentioned display, the display section 04) also displays the reception area:-
Data, timing signals, output control, transmission/reception data, etc. can also be displayed.

Note that the PB control information sent from the telephone is a 10-code control signal (load power on or off), and if the 10-code is, for example, 5 to 7 digits, and the control signal is 4 digits, noise and other noise may occur during reception and decoding. There is no need to worry about malfunctions caused by signals.

As described in detail, according to the present invention, it is possible to easily monitor and control the load status of the power supply at home etc. from a remote telephone, and its industrial utility value is extremely large. be.
