The reset unit 130 is a circuit for initializing a program when the CPU malfunctions. When the reset unit 130 presses SW0, the reset unit 130 initializes the CPU and the first to fourth interface units 150, 160, 170, and 180.

Reference numeral CN0 is a connector and is connected to the signal terminal of the remote control receiver 100 and P1.0 of the CPU so that the remote control signal is transmitted to the CPU. CN1 is also used as an input / output unit by connecting port 1 of the CPU 89C52, timer 0, and serial input / output port.

The first relay unit 151 and the second relay unit 152 illustrated in FIG. 5 are ten relays having two DC 5V and two contacts that turn on / off 10 external devices RL0 to RL9 in the system. It is used for the on / off action according to the state detection of doors, windows, boilers, air conditioners, and gas. The on-off action is controlled by the CPU through port A of the first interface unit 8255 # 1. In addition, since the relay cannot be directly driven by the power of the interface 8255, the NOT gate is embedded therein, and the relay is driven through the ULN2003 code that inverts the signal when outputting the program.

The latch unit 74HC573, which is not indicated, indicates that ports 0 and 2 of the CPU are used as the address and data bus of the system, and when using the 8-bit data bus system, only port 0 is a time-sharing multiplexing address bus and data bus.

It is usually controlled by the CPU and can be changed manually if the user wants to change it.

The voice memory unit 260 used TMM41256. As a memory for storing voice data, it is a DRAM (Dynamic Random Access Memory). The T6668 can connect up to four of them, so that the entire memory can be divided into 16 by arbitrary addresses to store up to 16 clauses. The choice of clause is determined by the 4-bit digital data assigned to the D0-D3 pins.

The first interface unit 150C55 # 1 Programmable Peripheral Interface (PPI) is a general-purpose parallel input / output interface device that can be used with an Intel-based microprocessor. Use to set. Port A is used as a key input and Port B and C are used as interface circuits for relay output.

Reference numeral 74LS11 is a TTL with an AND gate, and is used to connect Interrupt1 in parallel.

Bus Driver 220 The 74LS244 is a three-state bus driver designed to latch keys and key values here and read them whenever the CPU requires them.

DTMF Receiver 210 The HY8870 receives DTMF signals generated when a user presses a key to enter a password and turn on / off an external device with an external telephone, and separates the signals into upper and lower layers, and then decodes the signals into digital decoders. Send it to to analyze the key value. This value is output to the external latches (Q4, Q3, Q2, Q1) in binary format. It is also sent to the CPU through port C of 8255 # 1.

The ringtone detection circuit 153 is a circuit for detecting a ringtone when the user makes a phone call from the outside when the user goes out, and generates a sine wave signal of about 85Vp-p when a bell signal is generated. To receive the signal, the TTL circuit drops the voltage and turns the waveform into a square wave. However, the rising and falling rates of these square waves are so slow that the counter of the CPU is wrong, and the trigger circuit (74LS04) is used to make the waveform a complete square wave. The CPU reads this signal through Timer 1, sets the counter value, reaches the set counter value, turns on relay 10, and applies a resistance of 470Ω across the telephone line. This is a resistance value when you pick up the handset of a general telephone, and the function is to make the call automatically connected.

Port C is set as an output so that the phone can be controlled from the CPU by connecting to the TD0-TD3 to input the TEN terminal of the dialing IC (KS58015), the coil of the relay 11, and the telephone number.

Reference numeral 74LS11 is a logic circuit for use in parallel by connecting interrupt 1 with an AND circuit.

The dialer 186 KS58015 is an IC that receives 4-bit binary data from a CPU and generates DTMF signals. This causes the DTMF signal output to be suppressed when the TEN terminal is LOW, and outputs the data latched to D0-D3 to generate a tone when it changes to HIGH.

Speech Network (187) The KA8504 has a Tx amplifier, Rx amplifier, and DTMF amplifier inside to amplify DTMF to transmit and receive voice and to make calls to the other party.
