[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a home control system that includes security such as home crime prevention and disaster prevention, control of home appliances, control of intercoms, etc.

[Conventional technology]

The conventional home control system is NEC Technical Report, Vo.
t35. No. 9.1982, it has a configuration as shown in FIG. In this diagram,
(1) is the home monitor itself, (2) is the intercom attached to this home monitor +11, (31ti is the same as the above home monitor (fire sensor, C4, which is one of the crime prevention and disaster prevention functions that are the main functions of 11) gas leak sensor, (
5) is a ventilation sensor, and (6) is a water leak sensor.

(7) is an intrusion sensor. Other inputs for housekeeping include a bath water level sensor (8), a bath water temperature sensor (9), a room temperature sensor, and two remote control switches (lη) for operating the entry light (not shown). There are 0 electric locks as output functions.

Operates in conjunction with the detection of a fire or gas leak (for example, instructs to stop when a fire occurs, and to operate when a gas leak is detected)
It has a ventilation fan stop relay 0, a ventilation fan activation relay I, a management room transfer output α9 for transmitting an abnormality in the room to the manager's room, and a connection signal with an intercom handset ae. (Details of other panel surfaces are omitted.) Conventional home control systems configured in this way have a single centralized control panel (or monitor panel) that provides the minimum functions necessary for housekeeping or home control. ), each input/output device and the controller body must be connected in a star connection (one-to-one arrangement fa), and alerts must be clearly communicated to the user using voice synthesis in the event of an abnormality. It is characterized by having the function of partially transmitting abnormality occurrences to the manager's room, and is considered to be a cost-effective method as a home control system for condominiums.

[Problem that the invention seeks to solve]

However, even in the case of condominiums, there are many rooms,
As a result, the number of devices to be monitored and controlled has increased, the installation location of each device has become far away from the central controller), and user demands have become as diverse as in a normal detached house. As the world's technology grows, it becomes impossible for conventional equipment such as the one mentioned above to cope with the situation. Specifically i
(2) The system lacks scalability.

(3) There is no functional compatibility between the intercom and the home control system; (4) there is no compatibility between the intercom and home control systems;
There are problems such as b. Furthermore, when an abnormal situation such as a fire or gas leak occurs, it is difficult to know where it occurred.

[Means for solving problems]

In order to solve the above problems, this invention has a microcomputer (hereinafter referred to as CPU) installed in each room.
Various sensors such as gas, fire, window, water level, hot water temperature, gas valve, etc. are installed in each room as necessary, and lighting equipment, air conditioners, and other sensors are installed in each room as necessary.
Rice cooker, 1! Mind lock.

Loads such as gas valves and baths are connected to the interface unit (
The status of these various sensors and loads is processed by the CPU and displayed via the IFU on the display device installed in each room. A switch and an alarm generating device are provided, and when the input signals from the various sensors or loads mentioned above are abnormal state signals, the alarm generating device in each room is operated, and the generation of the alarm and the operation stop of the device are provided in each room. A stop switch in the manual operation switch allows access to rooms other than the room where the abnormal condition signal was generated, even from other rooms, and stopping the operation of the alarm generator in the room where the abnormal condition signal occurred is performed by the manual operation of that room. This can be done using a stop switch inside the switch.

[Operation of means to solve the problem] Various sensors installed in each room, load 9 manual operation switch, alarm generating device, (3PU room monitor controller, distributed control, etc.) Centralized control is also possible by connecting via an information transmission path (hereinafter referred to as home bus).

Can ensure expandability and wiring savings, -? In order to avoid having to change the software (control program) when expanding the system, we have designed a system that eliminates the need to add anything at the time of installation or expansion, as long as a predetermined number of room monitor controllers are connected. Workability can also be ensured. In addition, in response to abnormalities in the sensor power installed in each room or changes in switch input, the CP and U distributed in each room perform local processing, and then transmit the changes to the room monitor controllers in other rooms. The method of communication is via the home bus. Furthermore, when this abnormal state signal is generated for 5 minutes, the CPU in that room processes it and generates an alarm sound, and also transfers it to each room via the home bus and operates the alarm sound generation device in other rooms. let

The alarm sound can be stopped by using the stop switch in the manual operation switch of any room other than the room where the abnormal condition signal was generated, but the alarm sound in the room where the abnormal condition signal occurred can be stopped in that room. Stop the machine for the first time by operating the stop switch in the manual operation switch.

C (engine C11) and switch (SWl) are power-on reset circuits that reset the hook IC when the power is turned on.

The operation of the home control system configured as above will be explained. When a fire occurs in the RMC-K shown in Figure 3, the fire sensor operates and its contact closes, the terminal (ON2) (2) is connected to GND and becomes "L".
become the level. The operation of this contact is inputted to OP[T (step 01) through the Schmitt trigger inverter (step C13) and capacitor (step C2B) to remove chattering. QPU (Engineering C1)
In this case, input 1 to the fire bit in the status address that indicates the status of the security sensor in the internal RAM, and input 1 to the fire bit in the change flag address to indicate that the fire status has changed from 0 to 1. 1 is input, and 1 is similarly input to the report request flag address. The fire and gas bits at this status address are almost regularly set to Plo of OP[J (Work 01).

It is inverted and output from Pit. Therefore P.I.G.
The state becomes L, and the output aυ of (engine C9) also becomes L, and the fire LED lights up to indicate that a fire has occurred. On the other hand, PL5. distinguishes the status address data into fire, gas, emergency, and window switches, creates alarm sound codes corresponding to each, and outputs the codes. Compared to the data of Pl6, Pl5. which has a higher priority code. Pl6
Output to. The priority of the alarm sound is based on the water level, taking into consideration the degree of danger.

The order is water temperature → emergency, window switch → fire, gas. The code for the alarm sound in case of a fire is given top priority.
, pts to recognize the Pll status. If Pl7 is 0, some kind of alarm sound has already been generated, so by outputting 1 to Pl7 for a certain period of time, and outputting 0 again after stopping the alarm sound, audio engineer 0 (engineer 03) can set Pl7 to Pl7.
l5. Receives the alarm sound code in the event of a fire output to Pl6, and generates an alarm sound. Voice IC (engineering 03)
), the output of the terminal (DO) is set to 0N10F according to the frequency of the alarm sound generated in accordance with the code of the alarm sound.
F. At this time (Dl) is 0. Since (D2) is outputting 1, the transistor (Q) is turned on, and (
The output voltage of Do) is shaped into a nearly sinusoidal waveform by a filter consisting of a resistor (R5) - (R6) and a t capacitor (010,011), and is amplified by an amplifier (-[010) and output to a speaker (C). drive and generate an alarm sound. In this case, the alarm sound corresponds to a fire. Also (Pl5),
When the alarm sound generation code is output to (Pl6), (P
If l7) is 1, it means that the alarm sound is generated and the power is strong, so it is possible to input the code of the alarm sound to the audio engineer C (engineer C3) just by outputting (Pl7) KO. It is. Furthermore, (Dl) of the audio IC (engine 05) is a terminal used when the generated sound is enveloped, for example, like Bing-Pong, and outputs 0 when outputting audio, and resistor (R11).

A capacitor (C8) is charged via a diode (D9), a transistor (Ql) is turned on to generate sound, and 1 is output to (Dl) at the timing when an envelope is applied. This turns on the transistor (C2), and the charge on the capacitor (C8) is transferred to the resistor (R1), (
R8), the base current of the transistor (Ql) gradually decreases, and the voltage drop between the collector and emitter gradually increases.

Therefore, the generated sound has an envelope and gradually becomes smaller. In addition, (D2) is the alarm sound that is generated, that is, (work 0
This is to automatically adjust the sound volume depending on the type of alarm sound code input in 5), and in the case of an alarm sound code that occurs when a security sensor is activated, such as a fire or gas leak to notify an emergency situation. output 1 to increase the volume,
0 is output for the notification sound code when the water level and hot water temperature sensors are activated. When 0 is output to D2, the transistor (C2
) collector voltage is resistor (R10), (R11)
The base voltage of the transistor (Ql) decreases, and the voltage drop between the collector and emitter increases.

Resistor (R5), (R6) t capacitor (010),
The input voltage to the filter such as (011), that is, the input voltage to the amplifier (engine Cl0) decreases, and the volume of 1 generation becomes small.

In this manner, when the fire sensor detects the occurrence of a fire, the occurrence of the fire is notified through a display and an alarm sound at the R'MO-K. On the other hand, when 1 is input to the fire bit at the report request flag address on the internal RAM, 0 is input to the fire bit at the change flag address, indicating that the processing for the change in the contents of the status address has been completed. When 1 is input to the report request flag, the CPU (engineering C1) sends the engineering FM (
IC2) notifies other RMCs via HBB. In other words, cpU (technique 01) is cpU (technique 01)
2) is sent via the pp engineer (tech 04) to the destination address, control code, byte count indicating the number of bytes of data that follows, and the status of the security sensor to notify that a fire has occurred. DB?
and is given as parallel data from the INT, RD WR terminals, etc. 17M (engineering C2) converts the received data into serial data in a predetermined format and transmits it via the HBS.

All other RMOs connected to the HBS will receive this data. For example, when RMO...E receives this data, it recognizes that a fire has occurred from the contents of the data field, recognizes the location of the fire from the source address, and enters 1 in the fire bit of the other room status in the internal RAM. do. The state of this status is O as in the case of RMO- above.
P[T(101) is output to Plo and lights up the fire LED. On the other hand, the audio IC (engine 03) generates a fire warning sound. Also, the results of recognizing the location of occurrence are categorized by type of RMO, for example, RMO-, the kitchen, RM (1!
-B is installed in a bathroom, RMC-E is installed in the entrance, and RMO-G is installed in a general-purpose room such as a small room or bedroom, so it is displayed as a private room, and it does not identify the room in which the RMO is installed, but rather what type of RMO it is. By recognizing and displaying the RMC, it is possible to reduce the number of RMCs to only the type of RMC that indicates the location of occurrence.

These displays, along with other displays, indicate the P of cpU(IOl).
Serial data from I3 is output to the LCD drive circuit along with the clock of PI3, and when 1 is output to P14, the LCD is driven according to the data output from PI3, and the fire display, entrance display, etc. are lit. At the same time, the alarm sound stop display lights up, and when the sound stop SW is activated, the signal is input from pa2 to the CPU (work 01).

1 to PI3 of CPU (engineering 01) by the operation of sound stop SW.
Outputs and stops the operation of the audio IC (engine 05).

Stop the alarm sound. On the other hand, when the sound stop SW is pressed, the CPU
(Work 01) is converted to Work FM (Work C2) in the same way as above.
Since the sound stop SW was pressed, input the data to stop the alarm sound and send the command to other RMs (3) via the HBS.
recognizes the emergency status of the room where the RMO is installed from the received data from the contents of the status address in RAM, and if the contents are all 0, outputs 1 to (PI3) of 0PU (engineering C1) and stops the alarm sound. do. At this time, the alarm sound stop command is similarly received by RMO-B, but since the fire sensor connected to RMO-B is operating, 1 is input to the fire bit of the RAM status address, and the alarm sound is stopped. There's nothing to do. When the sound stop SW of RMC-E is pressed, the alarm sound is unconditionally stopped, and the alarm sound stop display also disappears. Note that the fire display goes off in RMO-1 when the fire sensor is turned off, and other RMCs turn off the light as a special feature when they receive a notification that the fire sensor is turned off via HBB.

Next, the operation of the emergency switch will be explained. The emergency switch uses a button-button type switch. For example, when the emergency switch in RMO- shown in Fig. 3 is operated, an alarm sound is generated in the same way as when the fire sensor is operated, and there is no notification that the emergency switch is turned on via HBEI. In the RMO- shown in Figure 2, an emergency display, an alarm sound, and operation are performed.7' (RM
The type of O is displayed. At this time, unlike when the fire sensor is activated, the display on RMO- will not light up because the alarm will only stop when the emergency situation is lifted and the emergency switch is turned OFF. , and the sound stop switch does not operate. This operation makes it possible to prevent forgetting to turn off the emergency switch when the emergency situation is lifted.

Next, the window switch will be explained. RMO shown in Figure 3
-E, when the window monitoring SW is ON, that is, the window switch operates while the window is being monitored, the window switch OFF (window open) command is input to the CPU (engine ON) via P. P of CPU (Engineering C1)
An intrusion display is lit via the 2O, and an alarm corresponding to the occurrence of an intrusion is generated. However, in this state, there is a possibility that the window may be opened by mistake while monitoring the window, so
A display alarm sound is generated only in RMO-I, which notifies other RMOs from M (work 02) via HB8. At this time, I realized that I had opened the window by mistake and turned on the window switch (closed the window).
Stopping the alarm sound 9 It operates to turn off the display, and the alarm sound can also be stopped by operating the sound stop switch. but.

If a certain period of time passes with the window switch turned off, the CPU
(Work 01) notifies all other RMOs of the occurrence of the intrusion from the IFM (Work 02) via the HBS. The RMO that received this notification, for example, RMO-K [
Turn on the display and sound the alarm in the same way as in the case of a fire outbreak above.

Other RMOs also perform operations similar to RMO-.

In this way, by providing a delay time between turning off the window switch and notifying other RMOs, it is possible to prevent an alarm from being emitted throughout the house when a window is accidentally opened, and to prevent intruders from outside. An alarm can be generated from all RMOs.

In addition to the above-mentioned sensors, the RMQ-K shown in FIG. 2 is equipped with a gas sensor, a bath water level sensor, and a water temperature sensor. The gas sensor is 6V when the sensor is operating normally, 12V when detecting a gas leak,
Since the DC voltage of Ov is output when the sensor fails, PBl (work 04) inputs the result of determining this voltage by the comparator (work C14) from FBI and PBl. If a gas leak occurs, PBL will be 0. PBl is 0 when the sensor fails. Under normal conditions, FBI and PBl are both 1. This input is D
It is input to OP[T (・Eng C1) via O to D7. As a result, after a certain delay time in the event of a gas leak, HBS
Other RMOs are notified via. Other sensors input data to the CPU (engine C1) in the same way as the fire sensor, water level,
(water temperature cera) Alarm sound is generated according to the SW settings 9
Perform display.

As shown in Figure 3, 7' (RMO-In) has an electric lock control function. Terminal 4 (ON3) is an electric lock that locks and unlocks when energized; An unlocked electric lock can be connected.If the lock switch is pressed while the electric lock is in the locked state, 0 is output for a certain period of time (about 1 second) from (P21).This 8 is output. The solenoid of the locking/unlocking type electric lock is energized for 1 ft time to unlock it. At this time, the output of the flip-flop (C11) is also reversed and becomes 0, and the solenoid of the locking/unlocking type electric lock is energized when energized. When the lock SW is pressed again, a pulse similar to the above is generated at P21, and the instantaneous energized lock/unlock type electric lock is locked again.This pulse also reverses the output of the flip-flop (C11). When the power is turned on, the power to the unlocking type electric lock is also stopped and the lock is pressed.In the case of an electric lock that does not have an output function to know the status of the electric lock, turn the Jumba Socket (Jell) to 1-1. Drive output of electric lock that unlocks when energized by switching to side 2 (Q of flip-flop (work 011))
is used as a monitor input.

〔Effect of the invention〕

As described above, this invention installs an RMO in each room, and enables these RMOs to send and receive signals to each other via the home bus. The RMO also has a centralized management function. Furthermore, RMO can be easily added by connecting to the home bus, wiring is simple, and system expansion is easy. In addition, when an abnormal condition signal is generated, the alarm generating device is activated, and an alarm sound is generated, the alarm sound in the room other than the room where the abnormal condition signal was generated will be activated when the stop switch in the manual operation switch of any room is activated. If activated, it will stop, but the alarm sound in the room where the abnormal condition signal occurred will only stop if the stop switch in the manual operation switch in that room is operated. Therefore, since it is immediately known which room has generated the abnormal state signal, the user can immediately take measures such as investigating the cause and considering countermeasures.
