Description

The present invention relates to a disaster prevention system that operates an apparatus by receiving an alarm signal transmitted from a broadcasting station by an alarm of any of weather, terrestrial, tsunami, storm surge, wave, and flood.

Japan has an "Earthquake Early Warning (abbreviation: EEW)" system that quickly catches earthquakes that occur around Japan and issues an alarm before a large tremor arrives. This is one of the early earthquake transmission systems, which is a forecast / warning provided mainly by the Japan Meteorological Agency, and is a system that notifies residents in almost the entire country.
The issuance of Earthquake Early Warnings is legally maintained and is a mature system, but the receiving side has a high degree of freedom in installation and equipment selection by each individual and each company, and the receiving environment is left to each individual. Has been done.
Usually, this Earthquake Early Warning can be generally received by TV, radio, mobile phone, etc., and it can be received by using a dedicated line for advanced users.
Services for advanced users can obtain detailed information such as the detailed time until shaking occurs and the expected seismic intensity, but high initial introduction costs and monthly usage fees become problems, and each household and business The current situation is that it has not spread to places.
On the other hand, regarding reception using mobile phones, for example, educational institutions such as universities do not allow the use of televisions, radios, and mobile phones during examinations and lectures including experiments. In addition, elderly people and elementary and junior high school students who lack judgment and physical strength in the event of a disaster need to take further initial actions, but since the penetration rate of mobile phones themselves is low, we expect that this information will be disseminated. I can't hope for it.
Furthermore, many national examinations such as the National Center Test for University Admissions and national examinations clearly prohibit the use of mobile phones during the examination, and especially educational institutions receive emergency earthquake early warnings on a daily basis. There is no environment where it can be done.
As a solution to these problems, there is an earthquake early warning receiver using radio broadcasting as shown in Patent Document 1. This means that the radio broadcast is normally received while being muted, but the radio sound is played only when the chime sound peculiar to the Earthquake Early Warning is detected internally, and the Earthquake Early Warning is notified.
Further, Patent Document 2 discloses a device for shortening the cutoff of energy supply to consumers from the time of an earthquake.
Further, Patent Document 3 discloses a facility management device that selects and controls equipment to be stopped according to the intensity of seismic intensity and the arrival time of seismic waves when receiving an Earthquake Early Warning.

Universities and other schools are divided into many rooms, such as classrooms and laboratories, and classes are held in each place. Also, in factories and large-scale playgrounds, there are many cases where even the sound of the radio is drowned out and the original purpose cannot be satisfied. Furthermore, many laboratories such as universities and research institutes are designed with an emphasis on airtightness, and there is also the problem that radio waves cannot reach in the first place, so it has not yet become widespread. Under such circumstances, it is difficult to install a device like Patent Document 1 in all rooms and manage it on a daily basis within a limited time and budget.
In order to solve these problems, it is preferable to have a disaster prevention system that separates a master unit that constantly monitors Earthquake Early Warnings and a slave unit that starts various operations by radio signals from the master unit.
It consists of a master unit that receives radio waves from the broadcasting station and a slave unit that communicates with the master unit, and is transmitted from the broadcasting station by warning of weather, geography, tsunami, high tide, waves, or flood. If it is a disaster prevention system that receives the alarm signal to be issued by the master unit and notifies the alarm on the slave unit by receiving the operation signal from the master unit, install the master unit in a place with good radio waves and a good environment. However, by transmitting and receiving the communication between the master unit and the slave unit as a wireless signal, it is not necessary to consider the reception environment of radio waves when installing the slave unit, and the degree of freedom in installing the slave unit is significantly increased. In addition, since a repeater can be installed between the master unit and the slave unit, stable and wide-range operation can be ensured even in a complicated building.
By the way, the device of Patent Document 2 does not disclose measures against erroneous reception due to noise or the like.
Further, the device of Patent Document 3 is intended to select and control a device to be stopped according to the intensity of seismic intensity and the arrival time of a seismic wave, and does not disclose measures against erroneous reception due to noise or the like. ..

Upon receiving at 16, the slave unit 20 is authenticated, and the time when the slave unit 20 is authenticated is stored in the master unit storage unit 17 and the slave unit storage unit 23 as authentication time data.
According to this embodiment, for authentication between the master unit 1 and the slave unit 20, an infrared LED and a light receiving photodiode are used separately from the master unit transmitter 3 that transmits an alarm signal, and authentication time data is further used. Security can be enhanced by storing the unique information in the master unit storage unit 17 and the slave unit storage unit 23 and using it for authentication.

It has 25 and. The operation signal, the confirmation signal, and the reply signal transmitted from the slave unit 20 include the authentication time data.

In the case where the slave unit 20 is a receiver operating slave unit 20A that operates the receiver 30A, when the receiver operating slave unit 20A receives an operation signal at the slave unit receiving unit 24, whether or not the receiver 30A is in the viewing state. When the TV power ON detection unit 26A and the TV power ON detection unit 26A detect that the TV power ON detection unit 26A is not in the viewing state, the TV power ON instruction unit 27A transmits an instruction to turn on the power of the receiver 30A to the receiver 30A. When the slave unit receiving unit 24 receives the operation signal, the setting channel indicating unit 28A that transmits a channel switching instruction to the receiver 30A so that the preset channel can be viewed, and the power supply of the receiver 30A after a predetermined time elapses. It has an off timer indicator unit 29A for transmitting an instruction to turn off the image to the receiver 30A, and a volume indicator unit 29D for instructing the volume output from the receiver 30A.
When the receiver operating slave unit 20A detects that the TV power ON detection unit 26A is not in the viewing state, the receiver operates from the TV power ON indicator 27A, the setting channel indicator 28A, the off timer indicator 29A, and the volume indicator 29D. When an instruction is transmitted to the 30A and the TV power ON detection unit 26A detects that the TV is in the viewing state, the setting channel instruction unit 28A and the volume instruction unit 29D transmit the instruction to the receiver 30A.

When the receiver 30A is in the ON state, that is, in the viewing state, the receiver 30A is not turned off, for example. When there is no viewer, the power can be returned to the power-off state after a predetermined time, and when there is a viewer, viewing can be continued without turning off the power.
When the receiver 30A is provided with a off timer, the off timer indicator unit 29A described in this embodiment is preferable, but the receiver operating slave unit 20A may be provided with a timer unit. When the receiver operating slave unit 20A is provided with a timer unit, the timer time can be set by the slave unit operation unit 21.
The setting channel instructed by the setting channel indicating unit 28A is set in advance by the slave unit operation unit 21 and stored in the slave unit storage unit 23.
The signal output from the TV power ON indicator 27A, the setting channel indicator 28A, the off timer indicator 29A, and the volume indicator 29D to the receiver 30A is a remote controller provided in the known receiver 30A. It is preferable that the (remote controller) is the same as the remote controller signal (for example, an infrared signal) for operating the receiver 30A. The same remote control as the remote control signal for operating the receiver 30A is the signal output from the TV power ON indicator 27A, the setting channel indicator 28A, the off timer indicator 29A, and the volume indicator 29D to the receiver 30A. By using the cord, the receiver operating slave unit 20A can be used regardless of the manufacturer and model of the receiver 30A. In order to use it in correspondence with the receiver 30A of each manufacturer, the receiver operating slave unit 20A duplicates the remote controller (remote control) signal provided in each known receiver 30A, and copies the signal in advance. It has a function to memorize.

When the slave unit 20 is an automatic door operation slave unit 20B that operates the automatic door 30B, when the slave unit 20B receives an operation signal at the slave unit receiving unit 24, the automatic door operation sensor 31 detects it. It has a drive operation control unit 26B for operating the drive unit 27B to be operated, and a timer unit 28B for setting the operation time of the drive unit 27B. By operating 27B, the automatic door 30B operated by the automatic door operation sensor 31 is opened.
According to this embodiment, when an alarm is transmitted, the automatic door 30B can be opened for a predetermined time to secure an evacuation route, and if a power failure occurs within this predetermined time, the automatic door 30B is maintained in the open state. Therefore, the evacuation route can be surely secured.
The timer time in the timer unit 28B can be set by the slave unit operation unit 21.

In the case where the slave unit 20 is a lighting operation slave unit 20C that operates an emergency exit guide light (emergency light / sound source) 30C equipped with a sound source, the lighting operation slave unit 20C receives an operation signal at the slave unit receiving unit 24.

For example, even in an environment where a mobile terminal or a receiver cannot be used. , Can inform that it is an emergency.
Further, when the handset receiving unit 24 receives the operation signal, the lighting operation slave unit 20C causes the voice output control unit 27C to output voice for the output time set by the timer unit 28C. As for the voice output from the voice output control unit 27C, the user can freely memorize the voice content (for example, guidance on evacuation route and evacuation method) and language (for example, Japanese, English, or Chinese) by the handset operation unit 21.

FIG. 2 is a flowchart showing an operation mode in the alarm-linked disaster prevention system according to the present embodiment.
The alarm-linked disaster prevention system according to this embodiment includes a slave unit authentication setting mode (step 1), a master unit / slave unit communication confirmation mode (step 2), a radio wave reception status confirmation mode (step 3), and an alarm monitoring mode (step 3). Step 4) is provided.

In the slave unit authentication setting mode in step 1, the master unit 1 and the slave unit are arranged in advance so that the master unit 1 and the slave unit 20 are surely linked and the operation is started only by the operation signal from the corresponding master unit 1. This is a mode for pairing between 20.
Generally, as a pairing method, there are security systems represented by ordinary Wi-Fi communication, but they are not perfect for malicious users and often break through the security system. Communication may be made. Introducing into a disaster prevention system while having such problems can cause unexpected panic. Therefore, the wireless communication after pairing is based on the security system generally used for Wi-Fi, etc., but the wireless communication is not used for pairing, and the physical range is visible to the user. It is preferable to perform authentication by involving physical contact.
Therefore, the master unit authentication communication unit 16 and the slave unit authentication communication unit 22 are provided with an infrared LED for transmission and a photodiode for light reception, and in the slave unit authentication setting mode in step 1, the master unit authentication communication unit 16 and the child unit Authentication is performed with the machine authentication communication unit 22.
By using infrared communication consisting of an infrared LED and a photodiode for receiving light and using a pairing method that is completely independent of the wireless signal, the safety at the time of authentication is dramatically improved.
In this infrared communication slave unit authentication setting mode, the drive circuit is designed so that the infrared communication distance is extremely short, for example, the distance between the master unit 1 and the slave unit 20 is 10 cm or less.
Therefore, the user performs unexpected authentication by performing the slave unit authentication setting mode in a state where the master unit 1 and the slave unit 20 are in physical contact within the range where the master unit 1 and the slave unit 20 can be seen. It is possible to prevent authentication by remote control with malicious intent.
Further, in the slave unit authentication setting mode in step 1, the date and time information of successful authentication is stored in the slave unit storage unit 23 as unique information, and at the same time, the authenticated slave unit 20 is stored in the master unit storage unit 17.
The slave unit 20 stores the date and time information at the time of authentication in the format of MY year MM month DD day hh hours mm, and the master unit 1 authenticates together with the authentication date and time (YY year MM month DD day h hours mm minutes). Add the handset 20 to the handset list.

The communication confirmation mode between the master unit and the slave unit in step 2 is a function of periodically communicating between the master unit 1 and the slave unit 20 and checking the communication status between the master unit 1 and the slave unit 20. When a problem occurs such that the master unit 1 cannot communicate with the specific slave unit 20, it is necessary to urge the specific slave unit 20 to inspect. Therefore, all the slave units 20 registered in the master unit 1 are identified by having individual unique information.
Therefore, in the communication confirmation mode between the master unit and the slave unit in step 2, the authenticated authentication time data is transmitted from the slave unit 20 and collated with the authentication time data of the slave unit list held by the master unit 1 to operate the slave unit 20. Monitor the situation on a regular basis.

The radio wave reception status confirmation mode in step 3 is a function of periodically confirming whether the circuit in the master unit 1 is receiving the correct FM radio signal, and promptly prompting the inspection if there is a problem.
In places where the radio waves are weak or where there is a lot of noise, there is no guarantee that the radio waves will continue even though the radio waves have been confirmed in the initial installation state. In addition, by using a commercially available FM transmitter or the like, an illegal radio wave may be emitted, and a trouble aiming at a malfunction of this system may occur.
In the FM reception status confirmation mode in step 3, the reliable reception of the radio signal is confirmed by monitoring the time signal signal broadcast on time in the FM radio, and it is monitored that it is the correct radio signal.

In the alarm monitoring mode in step 4, the master unit 1 constantly monitors the alarm signal, and when the alarm signal is received, the operation signal is output to the slave unit 20, and the slave unit 20 that receives this operation signal outputs the operation signal. Operate the device 30.
In the alarm monitoring mode in step 4, the FM radio signal is constantly received, and the earthquake early warning signal is monitored as an alarm signal.

FIG. 3 is a diagram illustrating an infrared pulse signal in the slave unit authentication setting mode.
FIG. 3 shows a format in which RPP (Random Pulse Pairing) in authentication between the master unit 1 and the slave unit 20 is transmitted as an infrared pulse, and is a case where the bit length is 4 bits and the bit string is 1011.
The RPP generates a multi-bit random pulse by a built-in control unit (microcomputer / microcontroller). This can be freely set depending on the scale of the system. For example, when a 32-bit random bit is generated, 4,294,967,295 (more than 4 billion combinations) combinations can be created. The generated random bits are treated as "1" and "0" signals, respectively. Here, for example, the infrared pulse is turned ON for the bit generated as "1", and the infrared pulse is not generated for the bit generated as "0".
As shown in FIG. 3, the controlled infrared pulse is pulse-output from the infrared LED as optical signals of "yes (1)" and "no (0)", respectively, at the specified time t, and this is output. By restoring it, it can be directly handled as a bit signal.
The infrared light pulse output from the master unit 1 is received by the photodiode PD built in the slave unit 20, and authentication is started.

FIG. 4 is a communication conceptual diagram showing a general digital communication processing method and a communication processing method using PWMNum.
When the authentication is set, the slave unit 20 stores a code of YY year MM month DD day hh hour mm as unique information for the date and time of successful authentication. The master unit 1 can identify and display a defective slave unit (slave unit that cannot be contacted) 20 by storing the same unique information and collating the unique information each time communication is performed. A method of giving specific unique information to the slave unit 20 and controlling writing and reading of the code will be described as PWMNum (Pulse Width Modulation Numbering).
This communication process is an application of PWM (Pulse Width Modulation) in which a sawtooth wave having a constant frequency and a set value are compared and set to "1" until they match and "0" after they match. PWM is a control method that is generally often used in electronic control, and is used for motor control, illumination brightness control, and the like.

Here, for example, when the date and time at the time of authentication is 13:45 on August 8, 2014, a 10-digit decimal number such as "1408081345" is stored in the slave unit storage unit 23. When this is transmitted with the usual binary (1,0) bits as shown in FIG. 4A, a pulse train of about 34 bits is required from the number of digits.
At present, when pulse measurement is performed using a microcomputer that is also used in a control system such as a general electric product, it is considered that a pulse width of about 1 ms is required for each bit from the resolution. Therefore, it is considered that it takes about 100 ms including the time interval to transmit "1408081345". In communication control using the UART terminal, it is conceivable to set the transfer speed (unit per second) faster, but in a microcomputer, the UART bps setting is M / N times the frequency of the operating clock (M). Since both N and N are determined by positive integers), the error between the theoretical value and the set value increases as the speed is set. Generally, it is desirable to keep this error to less than 1%, but with inexpensive microcomputers, it is desirable. It is difficult to satisfy this accuracy with high-speed communication. In order to set bps more accurately, it is necessary to set the frequency of the crystal oscillator connected to the microcomputer to an integral multiple of bps, but XMHz (X is The choice of crystal oscillators with frequencies other than (positive integers) is limited. In this way, the operation of the slave unit 20 concentrates the calculation load on the UART terminal, and avoids the situation where the essential emergency earthquake flash signal cannot be transmitted. There is a need.

As another problem, the 34-bit numerical calculation exceeds the number of register bits in the 32-bit microcomputer adopted in this system, so that a complicated control program and calculation for repeating the bit calculation are required. Attempting to control these processes with an inexpensive and low-capacity microcomputer puts a heavy load on the microcomputer due to the complication of programs and control systems, and in addition to increasing power consumption, appropriate processing is continuously performed. There is concern that it will be difficult to do. This system is equipped with a function for checking the operating status of the handset 20 on a daily basis and a function for monitoring the correct reception of radio waves by the time signal described later. Therefore, it is necessary to perform a plurality of input / output processes with one general-purpose microcomputer. It is not known when the actual emergency earthquake flash report will occur, and even if it occurs during the operation check of the slave unit 20 or the radio wave check by the time report later, this process must be performed with the highest priority. In anticipation of such a situation, it is necessary to dedicate the UART terminal to RPP and Earthquake Early Warning, and to effectively utilize other limited input / output terminals for processing such as checking the operation of the slave unit 20.

Therefore, as shown in FIG. 4B, the pulse width itself is regarded as numerical information and processed.
In this processing method (PWMNum), each pulse width composed of "1" and "0" corresponds to a decimal numerical value as it is.
That is, here, there are a total of 10 pulse widths corresponding to the numerical values 0 to 9, and by continuously outputting 10 pulses, "1408081345" is transmitted with one digit as one pulse.
When the slave unit 20 responds to the master unit 1, the date and time at the time of authentication stored in the slave unit storage unit 23 in the slave unit 20 are sequentially output as a pulse train having a time width corresponding to each number. .. For example, assuming that the date and time at the time of authentication is 13:45 on August 8, 2014, the slave unit 20 stores "1408081345" in the slave unit storage unit 23. When the slave unit 20 responds to the call from the master unit 1, “1” “4” “0” “8” “0” “8” “1” “3” as shown in FIG. 4 (b). Pulses having a width corresponding to each numerical value, such as "4" and "5", are sequentially output. The master unit 1 converts the pulse train included in the response from the slave unit 20 into a numerical value and collates it with the slave unit list to be held.

In this way, the authentication time data is composed of a plurality of digits, one digit is represented by one pulse of an arbitrary width, and the pulse width is made different depending on the numerical value (PWMNum), which is inexpensive and general-purpose. Since the PWM control method that is installed as standard in the microcomputer can be used as it is as an input / output terminal, stable communication accuracy can be realized with a simple control system.
Further, in an IC, particularly an IC using a CMOS process which is currently the mainstream, a current flows when the CMOS of the gate constituting the output is turned ON / OFF when the output is turned ON / OFF, and the pulse reaches a certain value to operate. However, the time until the pulse rises is a loss of power consumption. For example, in the example of the date and time at the time of authentication (13:45 on August 8, 2014), it is necessary to turn the output ON / OFF up to 34 times in the case of 34-bit communication. On the other hand, in the processing method using PWMNum, the pulse width of 1 ms is used as the resolution, and the pulse widths of 0 ms (0) to 9 ms (9) are directly converted into decimal values. In that case, only 10 times will be required.
Generally, for a microcomputer in which an operating frequency of 10 MHz or more is set, 1 ms is a time capable of processing with a sufficient margin. Therefore, it is possible to communicate without omission even at a low transfer speed in which the error between the theoretical value of bps and the set value is low, and at the same time, the processing method by PWMNum (10 times) as compared with 34 bit communication (34 times (ON / OFF)). ON / OFF) can significantly reduce the power loss that occurs when the pulse rises. In particular, there are a plurality of slave units 20, and communication is performed between the master unit 1 and the slave unit 20 at a predetermined date and time. Considering the valuable power situation that occurs in the event of a disaster, a processing method that drives with low power is effective.
If a normal wireless LAN having high processing capacity is used, high-speed transfer is possible even if the processing method is not based on PWMNum. However, in this system in which the standby time is overwhelmingly longer than the operating time, it is not preferable to use a wireless LAN that consumes a large amount of power not only during transmission / reception but also during standby from the viewpoint of power saving.
With this system, it is possible to easily introduce energy harvesting that recovers minute energy existing in the natural environment such as sunlight and indoor lighting and uses it as electrical energy, especially in the event of an imminent power situation during a disaster.

FIG. 5 is a flowchart showing the slave unit authentication setting mode.
In the slave unit authentication setting mode in step 1, the master unit 1 and the slave unit 20 are physically connected so that the infrared LED for light output and the photodiode for light reception face each other. At this time, the distance between them shall be 10 cm or less.

In step 11, when it is determined that the master unit 1 and the slave unit 20 are within a predetermined distance, the master unit 1 and the slave unit 20 are switched on at the same time as they are connected to prepare for optical communication (step 12). ).
In step 12, at least when the master unit authentication communication unit 16 in the master unit 1 and the slave unit authentication communication unit 22 in the slave unit 20 are turned on, the master unit authentication communication unit 16 transmits an authentication signal (step 13).
In step 13, the control unit (microcomputer) built in the master unit 1 outputs a random bit generated by, for example, a random function defined in C language, as an infrared optical pulse from the master unit authentication communication unit 16. It is transmitted as optical information to the slave unit 20.
When the infrared light pulse output in step 13 is received by the slave unit authentication communication unit 22 (step 14), the slave unit 20 sends the received infrared light pulse back from the slave unit authentication communication unit 22 to the master unit 1 (step 15). ).
When the infrared light pulse transmitted in step 15 is received by the master unit 1 (step 16), the master unit 1 compares the transmitted infrared pulse with the infrared light pulse returned from the slave unit 20 (step 17). ..
In step 17, if the compared infrared light pulses are the same, it is assumed that the authentication is successful, and the master unit 1 stores the successfully authenticated slave unit 20 in the master unit storage unit 17 together with the authentication time (step 18).
The set authentication time is transmitted to the handset 20 newly set in step 18 (step 19), the authentication time is stored in the handset storage unit 23 in the handset 20 (step 20), and the authentication is completed. (Step 21).

If it is not received by the slave unit 20 in step 14, is not received by the master unit 1 in step 16, or authentication fails in step 17, the number of unreceived counts is counted based on the transmission from the master unit 1 ( Step 22), the same process is repeated up to a preset number of times to attempt authentication, and when the number of unreceived times reaches the preset number of times (Yes in step 23), it is processed as an authentication failure (step 24).
In this way, when the authentication is successful, the date and time (date and hour / minute) at the time of successful authentication is recorded in the slave unit 20, and the master unit 1 is added to its own slave unit list together with the date and time at the time of authentication. After that, communication or control is performed only between the authenticated master unit 1 and the slave unit 20.
The authenticated master unit 1 and the slave unit 20 always perform wireless communication including this unique information in the subsequent communication. Therefore, communication between the master unit 1 and the slave unit 20 that do not have a parent-child relationship due to direct contact cannot be communicated because the unique information does not match.

FIG. 6 is a flowchart showing a communication confirmation mode between the master unit and the slave unit.
In the communication confirmation mode between the master unit and the slave unit in step 2, the time monitoring unit 8 constantly monitors the time (step 31) and determines whether or not the preset alarm condition is satisfied (step 32). Here, the alarm condition can be arbitrarily set in advance by the master unit operation unit 15, and is, for example, midnight every day or a time when communication confirmation between the master unit 1 and the slave unit 20 is performed. It may be set to the same time as the time signal time in the FM reception status confirmation mode.
In step 32, when it is determined that the alarm time set in advance has been reached, the master unit 1 transmits a confirmation signal to all the slave units 20 (step 33). The confirmation signal includes an RPP to individually identify each slave unit 20.
In step 34, when the slave unit 20 receives the confirmation signal from the master unit 1, the slave unit 20 transmits a reply signal to the master unit 1 (step 35). The reply signal includes RPP and unique information in order to individually discriminate each slave unit 20.
In step 36, when the master unit 1 receives the reply signal from the slave unit 20, the master unit 1 determines whether or not the unique information included in the reply signal matches the slave unit list (step 37).
If the unique information matches the slave unit list in step 37, the communication confirmation between the master unit 1 and the slave unit 20 ends (step 38).

If it is not received by the slave unit 20 in step 34, is not received by the master unit 1 in step 36, or the unique information does not match in step 37, the number of unreceived times is counted based on the transmission from the master unit 1. (Step 39), the same process is repeated up to a preset number of times, and when the number of unreceived times reaches the preset number of times (Yes in step 40), the communication deficiency warning unit 14 issues a warning as a communication deficiency (step 39). 41). In the warning given by the communication defect warning unit 14, the individual number of the problematic slave unit 20 is displayed and an alarm prompting the inspection is turned on.

FIG. 7 is a flowchart showing a radio wave reception state confirmation mode.
In the radio wave reception status confirmation mode in step 3, the time monitoring unit 8 constantly monitors the time (step 51) and determines whether or not the alarm condition set in advance, that is, the time signal time has been approached (step 52).
In step 52, when it is determined that a predetermined time has come from the preset time signal time, for example, 5 seconds before the time signal time, the activation unit 9 activates the time signal receiving unit 4 (step 53). For example, in the case of the master unit 1 capable of radio viewing, the ON / OFF state of the master unit 1, that is, the activation state is detected prior to step 53, and when the master unit 1 is in the OFF state, the step is performed. You may start by 53. Further, when the time signal receiving unit 4 is always activated, it is not necessary to activate it in step 53.
In step 52, when it is determined that a predetermined time has come from the preset time signal time, for example, 5 seconds before the time signal time, the tuning unit 10 tunes the time signal receiving unit 4 to a preset frequency (step 54). In this embodiment, the tuning in step 54 is performed after the time signal receiving unit 4 is activated in step 53.
After activating the time signal receiving unit 4 in step 53, after tuning in step 54, the mode shifts to the time signal detection mode (step 55). In the time signal detection mode in step 55, when the master unit 1 is, for example, a radio capable of radio viewing, the OFF operation in the time signal receiving unit 4 and the frequency setting change are restricted.
In the time signal detection mode of step 55, the time signal is detected (step 56).
When the time signal is detected in step 56, it is determined whether or not the detection time and the time in the clock unit 7 match (step 57).
If the detection time and the time in the clock unit 7 match in step 57, the viewing frequency is tuned to the viewing frequency before tuning in step 54 (step 58), and the time signal detection ends (step 59).

If an accurate time signal cannot be detected in step 56, the radio wave reception status warning unit 6 warns that the radio wave reception status is poor (step 60).
In step 57, if the detection time and the time in the clock unit 7 do not match, the clock correction unit 11 corrects the time in the clock unit 7 (step 61). In this embodiment, the time match of the clock unit 7 is determined in step 57, but the time of the clock unit 7 is always changed to the detection time without determining the time match of the clock unit 7. You may.

FIG. 8 is a flowchart showing the alarm monitoring mode.
In the alarm monitoring mode in step 4, the alarm receiving unit 2 constantly monitors the alarm signal (step 71), and when the alarm signal is received in step 72, the operation signal is output from the master unit transmitting unit 3 (step 73). ).

Steps 74 to 80 are flowcharts showing a processing flow in the receiver operating slave unit 20A. In this embodiment, in the receiver operating slave unit 20A, at least the slave unit receiving unit 24 and the slave unit authentication communication unit 22 are always in the operating state, but other functions are stopped.
In step 74, when the slave unit receiving unit 24 in the receiver operating slave unit 20A receives the operation signal in step 73, the receiver operating slave unit 20A is activated (step 75).
After the activation in step 75, the TV power ON detection unit 26A detects the ON / OFF of the receiver 30A (step 76).
When it is detected in step 76 that the receiver 30A is in the ON state, the preset channel set in step 77 is instructed, and the volume preset in step 78 is instructed.
