The senna detects the signal and detects whether the load is switched on or off from changes in this detection signal.

Hereinafter, one embodiment of the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a diagram showing an example of the configuration of the system of the present invention, in which an outdoor power supply of $1.2 is connected to a breaker 5 installed at indoor pressure.
It is connected to the. In this embodiment, the supply IIE line 4.5 via the breaker 3 is connected to a filter 6 that prevents carrier wave intrusion and leakage, and the filter 6 and each indoor outlet 9° 15, 20, 27, 31, 55 are Indoor power supply line 7
．． Connected at 8. Now, it is connected to the outlet 9 by a central monitoring control device 12 or electric wires 10 and 11, and an appliance slave device (a type of control bell) 16 or electric wire 14.
．． 15 to the outlet 16, and
A device 19 such as a television is connected to the appliance 616 with an electric wire 17.18, and just in case, a lamp unit (a type of control unit) 23 is connected to an outlet 2o with a power of 1121.22 K, and a lamp chiro 25VC is connected to the outlet 2o.
Suppose that M4 light device A2 (S) is connected with electric wire 24.25.Furthermore, fire center device 11i+ (a type of city device) 5Q is connected to outlet 27 by electric @2B, 29, and gas sensor is connected as a slave device. (-Seki, a kind of litei bell) 54 is electric ll52.55 K, so 2':/Se':/
It is assumed that the intrusion sensor subunit 38 is connected to the conduit w:y to ss via the electric wires 56 and 571c. Outlet 9.15,20,27.
51.35, the sharp object 12, the appliance holder 16, the lamp holder 23, the fire alarm 30, the gas sensor holder 34, and the intrusion sensor 38 are first connected to the microcomputer, which is its main component. (Microcombi, detailed after the abbreviation) performs initialization processing, and the sharp device 12 receives the input signal from the key on its panel or the sub device 1.
6, 23, 50, 54, and 58, the appliance remote control 16 waits for a signal from the sharps 12 or to turn the appliance 19 on or off.

The lamp module 2 is in the state of waiting for the input signal to change due to
5 is also in a state of waiting for a signal from the @ device 12 or an input signal of a change due to turning on or turning off the lighting device 26. In this state, both the appliance unit 16 and the lamp unit 25 are off. The fire sensor premonition 50 is in a state of waiting for an input signal indicating an abnormal state due to a fire.
Similarly (the gas sensor 54 is in a state of waiting for an input signal of an abnormal state due to a gas leak.Furthermore, the slave device 58 is in a state of waiting for an input signal of an abnormal state due to a gas leak.Furthermore, the slave device 58 is in a state of waiting for an input signal of an abnormal state caused by a gas leak. It is in the state of waiting for an input signal.However, if the sharp device 12 and each Seki & Reitaiko! 30° 54.58 are supplied with voltage from Pa, Kua, Pupa, Terry, that voltage is supplied. When the microcontroller is released, the microcomputer performs two-searization process.Here, the control module is separated from the appliance module by 16 seconds,
An example of the operation of the system shown in the figure will be briefly explained using the fire alarm device 3'O from the fire alarm. tf appliance girl! We will explain from operation 16. Now the user is sharp weapon 1
When the key No. 2 is pressed, the sharp tool 12 corresponds to the key input and sends a PPM-M signal of a predetermined code from the electric fi 10.11 to the outlet 91C. This sent ratio signal passes through the indoor power supply line 7.8 from the outlet 9 and reaches the outlet 15. In addition, outlet 1
5 to electricity 1114.15 through 1 appliance slave 1
Enter 6. The appliance remote control 16 compares the transmitted signal with the nine codes previously determined for the appliance remote control 16, and ignores any difference.

If the transmission code is the same, power is supplied to the appliance 19 if the transmission code is designated as on, and power supply is stopped if the transmission code is designated as off. Here the transmission code, i.e. P
The PM-M signal is the voltage (
50Hz or 60Hg) at a specific phase from the zero crossing.
6 sends an anti-pack signal to the sharp tool 12. This Anne f
The A-tsuku signal (PPM-5M signal) travels in the opposite direction along the same thread path of spinning and enters the sharpener 12. - The appliance 12 receives the interrupt signal from the appliance remote control 16, confirms that the previously transmitted signal has reached the appliance remote control 16, and stores the operating status of the appliance remote control 16. , and if the switch of the appliance 19 such as the 0th and 1st television set that displays its status is turned off by the user, the appliance 16 will generate a current flowing through the electric wires 17 and 18 (whether the appliance 16 is in the off state). (Also, power is supplied to the appliance 19 at high impedance.)
detects a change from the previous state of the instrument 19
is turned on or off. From this result, the appliance remote control 16 changes state t-on or off to start or stop supplying power to the appliance 19. At the same time, a predetermined code signal is transmitted to the sharpener 12. (This will be explained in detail later.) The electric appliance 12 receives this signal and changes the display as well as the memory of the operating state of the appliance slave device 16. Next, under this condition, the indoor power supply line 7.8 9. The power supply stops due to a power outage or breaker 5 trips (turns off). Since the appliance slave device 16 has no power, power, power, or power, it completely stops operating and enters the OFF state. On the other hand, the sharp instrument 12 is
Keep it moving with Kua, Pupa, and Terii.

However, the display is off [1], control premonition 16.
The key human power related to 23 is ignored.

The reason why the sharpener 12 detects the stop t depends on the presence or absence of a companion phase signal that synchronizes transmission and reception. This point will be discussed later. Eventually, when the power outage or the breaker is turned off and power is supplied to the indoor power supply lines 7 and 8611, the appliance slave unit 16 performs the initialization process and stands by. The sharps device 12 detects the restoration of power and resets the storage contents of the appliance slave device 16t to the memory contents of the sharps device 12 (the state before the power outage, etc.) using the port 9. Next, the operation of Fire Senna Chihiro 30 will be explained. Fire Senna Chihiro 30 monitors the occurrence of fires based on the presence or absence of smoke. If a fire breaks out, the fire sensor Chihiro 50 detects the fire and generates a buzzer sound, and also sends a PPM-M signal of a predetermined code from the electric wires 28 and 29 to the outlet 274C. This good signal is sent from the outlet 27 to the indoor power supply line 7.8t4. ? , reaches outlet 9.

Further, from the outlet 9, the electric current passes through the electrical outlet 110.11 and enters the sharps 12. The Il device 12 receives the transmission signal from the fire senna Chihiro 50, stops displaying the control premonition 16.23, displays a fire display, and generates a buzzer sound.

In addition, the key human power related to control premonition 16.25 is ignored. The fire sensor premonition 50 generates a buzzer sound until the fire detection signal disappears, and also outputs a PI'M message of a predetermined code at regular intervals.
Send. The sharp tool 12 receives this signal and generates a buzzer sound, or if a predetermined period of time elapses after receiving the above-mentioned signal sent from the fire-censor device 30, the buzzer sound will be generated and the fire will be detected. This will stop the display and return to the original state. Therefore, fire sen? When the transmission signal from 30 disappears, it returns to its original state. Here the transmitting code i.e. PPM-AM double signal indoor feeder line 7.8
It is synchronized to a specific phase from the zero cross of the voltage (50 Hsi t or 60 Hg) applied to. Next, assume that the power to the indoor power supply lines 7 and 8 has stopped due to a power outage or the breaker 3 tripping. fire senna chihiro 3
0 has Pa, Kua, Pupa, and Terry, so it has the action tm. Now, if a fire breaks out, the fire sensor device 30 detects the fire and generates a buzzer sound, and the PPM-AM multiplier signal device 1 of the predetermined code.
Send to 2. The sharpener 12 detects the beginning of the transmitted code at the rising edge of the sent signal and receives it. The following is the same as above. The Tsuma Sea Fire Senna Premonition 30 (Seki 1 Retainer) normally uses the voltage (5
The signal is transmitted in synchronization with a specific phase from the zero cross of 0Hss or 60Hz, and in the event of a power outage, the signal is transmitted asynchronously. The sharpening device 12 normally (similarly K) receives signals in synchronization with a specific phase from the zero cross, and in the case of a power outage or the like, detects the rising edge bt of the transmitted signal and starts receiving. In addition, in the above transmission, both the sharp instrument 12°chi 16.2L3o and 54.38 first receive the signal (
If there is no noise (the same applies to noise), transmission will begin.

In addition, the display of the sharp weapon 12 gives priority to the control premonition 16.23 and the security device 30, 54.58. The fire sensor premonition 50 was made to be prioritized for both the sensor sensor 34 and the gas sensor 54.

More sex.

The retail warning bell 50.34.58 has a pack-up battery, but when the voltage of this Pa, Kua, Pupa, Terry drops below a predetermined level, it generates a buzzing sound.
A predetermined transmission code is sent to the sharp instrument 12. The sharp object 12 is displayed in substantially the same manner as described above and generates a buzzer sound.

(It should be noted that similar items such as keys and switches are called separately for the purpose of simplifying the explanation that follows.) Next, the circuit configuration of the parent 1G12 in Figure 2 is shown in Figure 5. It is shown in the figure and briefly explained. In the figure, 39 is the same plug as in FIG. 2, and 10.11 is a wire connected to the plug 39. The arrows in the figure indicate the flow of signals, and the diagonal lines and numbers above the arrows indicate the number of signals. Electric wire 10

supply. Further, the power supply circuit 84 sends a pulsating voltage signal, which is a full-wave version of the AC voltage supplied by the electric wire 10.11, to the phase signal circuit 86. The phase signal circuit 86 generates a signal similar to the above-mentioned alternating current voltage (during macrocross) from this pulsating voltage signal and sends it to the interrupt input section NT1 of the microcomputer 98. The reset circuit 87 and the reset circuit 87 are connected to each other.

When the battery runs out, send a voltage signal to the circuit 88. The reset circuit 87 resets the microcomputer 9 (Hitachi nMo
544c), and the reset input section RI of the microcomputer 98 is raised to a predetermined level. This is to send a reset signal @ to the f811iT. The battery-out check circuit 88 sends a battery-out signal to the microcomputer 9 when the aforementioned DC stabilizing voltage voC drops to a predetermined level set slightly higher than that of the reset circuit 87. It is. 89 is a negative feedback circuit for oscillation, which sends two signals for oscillation to the microcomputer 98. The microcomputer 98 operates by generating black and white signals from this signal. The oscillating negative feedback circuit 89 also sends one high frequency signal for the indoor power line carrier to the transmitting circuit 99. The transmitting circuit 99 receives a high frequency signal sent from the oscillation negative feedback circuit 89,
The logical product of the transmission codes sent from the microcomputer 98 is taken and a signal is sent to the coupling circuit 100. The coupling circuit 100 includes the electric wire 1
0.11 K is connected, and when a signal is sent from the transmitting circuit 99, it is converted into a sine wave and sent to the electric wire 9.
It's crowded.

Conversely, when a signal of an indoor feeder carrier wave is sent from the electric wires 10 and 11, the coupling circuit 100 tunes to this and sends the signal to the receiving circuit 101. The receiving circuit 101 detects the signal sent from the coupling circuit 100 and sends a receiving code signal to the interrupt input section NTO of the microcomputer 98. Next, the microcomputer 98 controls the device 12 slave devices 16, 25, . ! +0.54.
Since the same product type and the same program were used for both 38 and 38, the microcontroller 98 can be configured with either of these settings (
In other words, in this case, it is the sharp instrument 12), but it is necessary to specify t-.For this purpose, the microcomputer setting code circuit 91
The establishment is a friend. Also, as a friend to prevent mischief.

Since we decided to prepare a transmitting/receiving code (called a mask code) that cannot be changed by the user, we needed a circuit for setting the mask code. This friend mask code circuit 92
has been established. The code settings for the circuits 91 and 92 from now on will be read by the microcomputer 98 during initialization processing of the microcomputer 98. 93 is the hack switch 59 in Fig. 2.
The Heuss code setting switch and its peripheral circuits are sub-circuits and can be read by the microcomputer 98 as needed. Reference numeral 94 denotes a transmitting LID1 path consisting of the LliD 58 and a driver circuit shown in FIG. 2, and numeral 90 denotes a buzzer circuit consisting of a buzzer 60, a buzzer switch, a chiro 1, and a driver circuit. These are turned on by the microcomputer 98 and also generate a buzzer sound. 97 is a switch/f circuit including the intrusion switch 62, on switch f80, and off switch 81 shown in FIG. 2, which sends a signal to the microcomputer 98. Reference numeral 95 is an LED array circuit made up of L11tD42-57 in FIG. 2 and peripheral circuits, and 96 is a key array circuit made up of keys 64-79 and peripheral circuits.

The microcomputer 98 sends a scan signal f:LII! This scan signal 1i is sent to the D array circuit 95 and the key array circuit 96.
Check and press keys 64 to 790 input using IK, and press L.
With the above-described circuit configuration, the device 12 shown in FIG. 2 operates as described in FIG. 1.

It progresses to 6jF. In the case of a power outage, the microcomputer 98 does not receive the output signal (key input) from the key array circuit 96, and also outputs (display) signals to the CD array circuit 95.

The signal is not sent until the signal from the retail bell is received, but the processing is done in the same way. When receiving the transmission from the warning bell (noise is the same), the microcomputer 98 generates an interrupt depending on the ship's clock E1 or Fis, and
The output of the scan signal is started from the middle of 1 or F2.

Let me explain.Now, if an interrupt is entered by the 1171 manual interrupt signal 01, the process will proceed to the synchronous processing (engineering NT1) routine.At this point, the interrupt will be sent to the INT i side, and the INTO In the synchronization processing (INTl) routine, the first scan signal (80AN1) is first raised as shown in FIG. Output the display data of 2 and start, then read the key data of 64 to 67! If processing is performed and the frequency is determined to be 50Hz, delay processing (approximately 0.2811

Move to 1l-UP-. In this process, the rising part of Dl or Di (the first half of the pulse) in Figure 4 (3) is processed, and the output of the receiving circuit 101 is first checked to see if there is no signal and if there is a transmission request. In this case, it sends a signal to the transmitting circuit 99 to start transmitting, and if there is a signal, it reads the signal, and if the frequency is determined to be 50 Hz, it performs delay processing (approximately α14g5). In this case, if the signal is 101 and a very short carrier wave signal is sent, the falling edge portion is also processed. Next, the first scan signal (S(!ANI

) and output the display data of L Iff D 46 to 49 in Figure 2 to start the demonstration, and then
The key data (inputs) 68 to 71 are read and viewed, and if the frequency is determined to be 50 Hz, delay processing (approximately CL14-1s) is performed. Next, the process moves to the second round transmission/reception process +x+ -D'25WN =. In this process, the process shown in FIG. 4 (the falling 9 part of Dl or Ds of J (second half of the pulse)) is performed, and if the signal @ for transmission is being sent to the transmitting circuit 99, it should be stopped. If a signal is being transmitted or received, a process is performed to determine whether the pulse width of the carrier signal, that is, the output signal of the receiving circuit 101, is appropriate, and if the frequency is determined to be 50HS!, then a delay is performed. Processing (approximately 0.28a

), and then 11! tD46-49
After performing processing such as ending the display of , the keys 64 to 79 read in advance are pressed.

f s o , it is determined whether the data input to the off switch 810 is correct, and it is determined whether the setting of the intrusion switch 62 has been changed, and if the data has been input correctly, that key or switch is Setting the transmission code and flag setting (setting) of the transmission request according to the

Also, at this time, a process such as making a confirmation sound by the buzzer 60 is performed. (Key discrimination processing) In addition, Uni, Toki-6

Elay processing (approximately 0.14 as) is performed. Next, the process moves to the 41st transmission/reception process t2)-D'15wN-. In this process, the falling edge portion of D2 or D4 in FIG.

Next, the fourth scan signal (8 (lAN4)) is turned down, and the display of LIDs 54 to 57 is terminated. After that, the process returns from the power outage and determines whether it is a friend or not. If there is a The processing time above is strictly controlled from the start of synchronous processing (INTl) due to interrupt occurrence, and is set so that it takes the same amount of time no matter which processing routine is passed through. .

In the next routine, first
) Release the interrupt caused by K and proceed to delay processing. If there is no power outage, an interrupt is generated by the INTl interrupt signal during this delay processing, and the process returns to the synchronous processing (INTl) again. Tsumashi, the time until this delay processing (in the middle) is 4th.
It is set to the half-wave time of the AC voltage waveform in Figure (1),
After the delay processing, that is, in the case of a power outage, the interrupt by the lNTl interrupt signal (al-Os) is first prohibited, and then the power outage processing is started. In the power outage process, processing is performed such as setting a scan signal @ (5OANI-BCAN4) output prohibition flag, setting a check start flag during power outage, and setting a setting request flag using a polling button for a control warning bell after power outage recovery. These flags are checked during the aforementioned synchronization process (NT1)/l/-chin and are used for processing as appropriate. Next, Figure 4 (4)
The interrupt caused by the INTO input interrupt signal (Ih or Es) is canceled, and if there is no interrupt, the process moves to the synchronization processing (NT1) routine.

In addition, from interrupt release (work NT1) to interrupt release (work NTO
) The processing time of the microcomputer 98 up to ) is actually sufficiently short compared to other processing routines, and since the time is adjusted within the 7'5som N1 startup processing routine, the overall processing time is Time management must be maintained properly. As described above, the processing routine continues even in the event of a power outage. Next, if an interrupt is generated by the NTO input interrupt signal E1 during a power outage, the process shifts to an asynchronous processing (NTO) routine. Furthermore, when an interrupt occurs, the interrupt is NT.

Both the 1 side and the INTO side are in an interrupt disabled state. In the asynchronous processing (NTO) routine, settings for specific input/output terminals of the microcomputer 98 and scan signals (SCAN1 to 80AN4) are performed.
) and performs memory change processing such as resetting (setting) the output prohibition flag, and then moves to the first transmission/reception processing (1)-UP- of the synchronization processing (INTl) routine. However, in reality, the process is moved to the middle of this process to ensure time adjustment.

It should be noted that, although the description has been omitted for the sake of ease of explanation, the process of determining the received ratio signal may be performed as appropriate in the four transmission/reception processes. The duration of the buzzer 60 is determined by counting the number of times the above-described processing routine is executed. fD5
The lighting of 8 is controlled by the transmission/reception process, and several other routines also control the horse. The II unit 12 operates according to the neural flowchart as described above.
