2. Description of the Related Art A house security system is a system provided for the purpose of crime prevention and disaster prevention of buildings such as personal homes and offices. This security system is provided in a building or at various places around the periphery thereof, and has a sensor for detecting data related to security, a master unit provided in the building for managing detection data detected by the sensor, and the building. It is configured by a notification device that is installed remotely and receives a notification of an abnormality from the base unit.

Specifically, a temperature sensor for detecting a fire, a gas leak sensor for detecting a gas leak, a human body detection sensor for detecting an intruder, a vibration sensor, etc. are used as the sensor. The detection data detected by each sensor is transmitted to the master unit via a wireless line or a wired line.

The base unit is for judging an abnormality in the detected data, and has a built-in automatic dial circuit for calling the registered telephone number (telephone number of the reporting device). The base unit is also connected to the notification device via a telephone line. When the parent device receives the detection data, the detection data is compared with a standard value stored in advance in the parent device to determine whether there is an abnormality. As a result, when it is determined that there is an abnormality, the reporting device is called by the automatic dialing circuit, and the reporting device is notified of "there is an abnormality" by a voice signal or an alarm sound.

The notification device is a telephone or a computer installed at a contact point of a security company or a building owner. The notification device is configured such that when the line is closed in response to the ringing sound from the base unit, a voice signal or an alarm sound transmitted from the base unit is output (from a speaker or the like). This allows security companies to quickly recognize the occurrence of abnormal situations, and to prevent disasters such as fires and gas leaks.
The damage caused by intruders such as thieves can be minimized.

However, the sensor provided in the above-mentioned house security system is often an analog sensor. In addition, the sensors are installed at various locations inside and outside the building (data detection positions), while the parent device that determines (processes) the detection data is installed at a location that is convenient for the user. That is, the analog data detected by the analog sensor is transmitted to the master unit located at a position distant from the sensor. An electric signal is affected by attenuation and noise during transmission, but especially for analog data, the signal waveform is likely to be disturbed due to the effect of noise. Furthermore, for analog data, although it is possible to amplify a signal that is attenuated during transmission, it is difficult to restore the signal waveform. For this reason, the analog data detected by the analog sensor tends to be inaccurate data, and there is a problem that the determination of the presence or absence of an abnormality based on the detected data is likely to be an error determination (decrease in reliability).

The slave unit 20 is a device for relaying the detection data detected by the sensors 2 to 6 and 28 to the master unit 40, and is provided with an MPU 21 as a one-chip microcomputer as shown in FIG.

The MPU 21 is an arithmetic processing unit having an arithmetic function and a control function, and stores the control program R.
The OM 22 and the RAM 23 that rewritably stores various data when the control program is executed are contained in one chip.

The ROM 22 stores a control program for controlling the slave unit 20 and various fixed values. Programs for data conversion processing (see FIG. 5) and detection data transmission processing (see FIG. 6) described later are stored in the ROM 22 as part of the control program.

The RAM 23, which is a rewritable memory,
The transmission memory 23a is provided. The transmission memory 23a is
This is a memory for temporarily storing the detection data to be transmitted to the parent device 40. In the slave device 20, the detection data is constantly sampled based on a predetermined sampling time, and the sampled detection data is stored in a predetermined area of the RAM 23. Then, the detection data stored in the predetermined area of the RAM 23 is written in the transmission memory 23a at the timing when the detection data request command transmitted from the parent device 40 is received. The data stored in the transmission memory 23a is transmitted to the master device 40 after the identification number of the slave device 20 is added. After transmitting the data, the data stored in the transmission memory 23a is cleared.

The MPU 21 is connected to the input / output port 24, and the external device 1 is connected to the input / output port 24.
0 analog sensor (temperature sensor 2, illuminance sensor 3, humidity sensor 4), A / D converter 25, human body sensor 28, setting switch 29, photocoupler 30
The photomos relay 31, the AC switch 32, and the first and second connectors 26 and 27 are connected to each other.

The A / D converter 25 converts the analog data detected by the analog sensors such as the temperature sensor 2, the illuminance sensor 3 and the humidity sensor 4 into digital data. The analog data conversion performed by the A / D converter 25 is performed by a general method, and the description thereof will be omitted.

The temperature sensor 2, the illuminance sensor 3, and the humidity sensor 4 are connected to the input of the A / D converter 25. The A / D converter 25 is provided with ports for connecting the respective sensors 2-4 corresponding to the respective sensors 2-4, and the respective sensors 2-4 are connected to the corresponding ports. The output of the A / D converter 25 is connected to the input / output port 24. The output of the A / D converter 25 is composed of signal lines corresponding to the connected sensors 2 to 4, and each signal line is connected to a predetermined port of the input / output port 24.

The analog data detected by the temperature sensor 2, the illuminance sensor 3 and the humidity sensor 4 by the A / D converter 25 is in the vicinity of the analog sensor.
It is converted into digital data and transmitted in the master unit 40 in the form of digital data. Therefore, the child device 20 can transmit a good signal with little signal deterioration to the parent device 40.

The human body sensor 28 is a thermal infrared sensor utilizing a pyroelectric element, and detects infrared rays from within the monitoring area. This makes it possible to detect a human body that emits infrared rays and detect an intruder.

The photocoupler 30 is a device for converting an electric signal transmitted from a connected device into an optical signal and inputting it. The gas leak sensor 5 and the smoke sensor 6 are connected to the photocoupler 30 as described above. The photocoupler 30 converts the digital signal transmitted from the gas leak sensor 5 and the smoke sensor 6 into an optical signal to emit light (at the light emitting section). The emitted light is received by the light receiving section which is arranged at a predetermined distance from the light emitting section, converted into an electric signal again, and input to the input / output port 25. Here, since the light emitting unit and the light receiving unit are not in contact with each other, a part of the signal transmission path is formed in noncontact. According to this, even if a large noise is included in the input digital signal (a large voltage load due to a lightning strike or the like), it can be blocked.

The photoMOS relay 31 is a power-saving relay and is connected to the buzzer 7. Buzzer 7 is a cordless handset 2
When the detection data detected by the sensors 2 to 6 and 28 connected to 0 is abnormal, it operates according to a command from the master unit 40 and outputs a buzzer sound. Here, buzzer 7
Consumes a large amount of power because it outputs a buzzer sound until the abnormality (alarm) is resolved. For this reason, the power consumption is suppressed by using the photo MOS relay.

The AC switch 32 performs switching operation of various connected devices based on the detection data of the sensors 2 to 6 and 28 connected to the slave unit 20. This switching operation is executed based on the command transmitted from the master device 40. Thereby, for example, if a lighting fixture is connected to the AC switch 32, the lighting fixture can be turned on based on the detection data of the human body sensor 28. Further, if a window opening / closing device is connected to the AC switch 32, the window can be opened / closed based on the detection data of the humidity sensor 4.

The first connector 26 is a connector for connecting the slave unit 20 to the master unit 40 or the slave unit 20 located on the master unit side. The second connector 27 is a connector for connecting the child device 20 located on the opposite side of the parent device side. The cordless handset 20 has 26, 27
A wired line 35 is connected to the slave device 20 and the slave device 20 or the master device 40 is connected via the wired line 35. Thus, as described above, it is possible to connect the plurality of slave units 20 so as to be connected to one data transmission path.

The master unit 40 is a device for judging the presence or absence of abnormality based on the detection data transmitted from the slave unit 20,
MPU 41 as a one-chip microcomputer, flash memory 45, EEPROM 46, input / output port 47
, LCD 48, input device 49, LED 51, buzzer 52, first connector 53, and second connector 54.
, An interface 55, and a mobile phone 56.

The MPU 41 is an arithmetic processing unit having an arithmetic function and a control function, and stores the control program.
The OM 42, a RAM 43 rewritably storing various data when the control program is executed, and a real-time clock (hereinafter simply referred to as “RTC”) 44 are contained in one chip. The MPU 41 transmits a detection data request command requesting the transmission of the detection data to each of the slaves 20 in order at predetermined timing (for example, about 10 seconds). In response to the transmitted detection data request command, until the detection data is transmitted from the transmission destination slave device 20,
The MPU 41 waits for command transmission to the other child device 20. As a result, even if the plurality of slaves 20 share one data transmission path (one wired line 35), signals do not collide.

The ROM 42 stores a control program for controlling the base unit 40, various fixed values, and the like. Management processing (see FIG. 3) and abnormality determination processing (S8) described later
The program (see FIG. 4) is stored in the ROM 42 as a part of the control program.

The RAM 43, which is a rewritable memory,
It has a reception buffer 43a and a transmission buffer 43b. The reception buffer 43a is a buffer memory for temporarily storing the detection data transmitted from each child device 20. Although signals and data are frequently transmitted to the parent device 40 from each child device 20, the data receiving speed is slower than the processing speed of the MPU 41. Therefore, if the MPU 41 is caused to perform the data processing while receiving the data, the processing of the data reception affects, and the processing efficiency of the MPU 41 decreases. However, the received data is temporarily transferred to the reception buffer 4

When the mobile phone 56 receives the telephone number and the mail data transmitted from the master device 40, it calls the received telephone number by the automatic dial circuit and transmits the mail data when the line is closed. As a result, the base unit 40
Then, the detection data is transmitted to the destination mobile phone 100 or PC 110 via the wireless line 60.

When the call signal is received, the portable telephone 56 transmits the call-in signal and the telephone number of the caller to the MPU 41 as a response request command. Based on this, base unit 4
At 0, it is determined whether or not the call is from the registered telephone number. Then, if the call is from the registered telephone number (reception of a valid response request command),
The response data transmission process (S15) described above is executed.

Next, with reference to the flow charts of FIGS. 3 to 6, each processing executed in the above house security system 1 will be described. FIG. 3 is a flowchart of the management process executed by the parent device 40. The management process is
This is mainly a process of determining the occurrence of an abnormality based on the detection data transmitted from the child device 20.

In this management process, it is first confirmed whether or not the security mode flag 46c is turned on (S1). House security system 1 of this embodiment
Is for ensuring the security of the absence house, so that the security mode can be arbitrarily canceled by the operation of the resident (owner). If the security mode flag 46c is off as a result of the confirmation in the process of S1 (S1: No), this management process ends.
On the other hand, if the security mode flag 46c is turned on (S1: Yes), it is confirmed whether a valid response request command is received (S2). As a result, if a valid response request command is received (S2: Yes), the process of S3 is skipped and the process proceeds to S4.

The response request command is a command transmitted from the mobile phone 56 to the master unit 40 when a call signal arrives at the mobile phone 56. Each time a call signal arrives from the mobile phone 56, a response request command (an incoming call signal and the telephone number of the caller) is transmitted to the master device 40, but the master device 40 stores it in the phone number memory 46d ( It is set to send detection data only to registered phone numbers. Therefore, when the master device 40 receives the response request command from the mobile phone 56, it determines whether the received telephone number is the registered telephone number, and responds only when it is the registered telephone number. This management process is continued with the request command as a valid response request command.

As a result of the confirmation in the process of S2, if the response request command is not received correctly (S2: N
o), it is confirmed whether or not it is the data reading time (S3). As a result of the confirmation, if it is not the data reading time (S3: No), this management process is ended. On the other hand, as a result of confirmation in the process of S3, if it is the data reading time (S3: Yes), the identification number of the slave unit 20 is added to the detection data request command, and the command is transmitted to each slave unit 20 in sequence (S4). That is, the data request from the master device 40 to the slave device 20 is periodically performed at predetermined time intervals, and is executed in response to a data transmission request from the mobile phone 100 or the like connected via the mobile phone 56. It

After the processing of S4, it is confirmed whether or not the detection data transmitted from the child device 20 has been received (S5). As a result, if the detection data transmitted from the child device 20 is received (S5: Yes), the received detection data is written in the reception buffer 43a (S6). Then, it is confirmed whether or not the detection data transmitted from all the slaves 20 is received (S7), and if the detection data transmitted from all the slaves 20 is received (S7: Yes). ), The abnormality determination process is executed (S8).

After the execution of the abnormality determination processing (S8), it is confirmed whether or not it is determined that the temperature sensor 2, the human body sensor 28, the gas leak sensor 5, and the smoke sensor 6 have abnormality (S9).
As a result, if there is no abnormality (S9: No), S2 to S9
It is confirmed whether or not the series of processes of No. is executed based on the response request command (S10), and if the process is not executed based on the response request command (S10: No), it is stored in the transmission time memory 46e. It is confirmed whether or not the scheduled transmission time has arrived (S11).

If the scheduled transmission time has not come (S11: No), this management process is terminated. on the other hand,
If the scheduled transmission time has come (S11: Yes), the scheduled transmission process is executed (S12). This scheduled transmission process (S12) is, for example, when the operator has designated the scheduled transmission (the scheduled transmission flag 46b is on), the cellular phone 100 in which the read detection data and the presence / absence of abnormality are registered. It is a process of transmitting to. After the execution of the scheduled transmission process (S12), each process (S13) is executed, and the management process ends.

Each process (S13) is a process for transmitting a command for causing the slave unit 20 that is the transmission source of the detected data to perform a predetermined operation based on the detected data transmitted from the slave unit 20. Specifically, in each of the processes (S13), a process of transmitting a command to call the buzzer 7 to the slave device 20 connected to the sensor in which the abnormality is detected,
A process of transmitting a command to operate the AC switch 32 is executed.

As a result of confirmation in the process of S5,
When the detection data transmitted from the child device 20 is not received (S5: No), an error determination process is executed (S5).
14). The error determination process (S14) is a process of detecting an abnormality in the slave device 20. Although the detection data is transmitted from the child device 20 based on the detection data request command transmitted from the parent device 40, if the detection data from the child device 20 cannot be received within the predetermined time, the parent device 40 , Cordless handset 2
It is determined that the detection data from 0 has not been received, and this error processing (S14) is executed. In the error process (S14), a process of transmitting a command for confirming the connection state and a process of retransmitting the detection data request command are executed for the slave device 20 that has not received the detection data. If the detection data is not received even after the execution of such processing, the child device 20
To determine the error. Error determination process (S14)
When an error is determined in step S5, the process from S5 is executed on the assumption that the detection data of 0 has been transmitted from the slave device 20 that has determined the error. In this error determination process, the standby time for data reception is set to a time that does not significantly affect other processes, for example, approximately 1 second to 2 seconds.

Furthermore, as a result of confirmation in the process of S7,
If the detection data transmitted from all the slaves 20 have not been received (S7: No), the process proceeds to the process of S5. In addition, as a result of the confirmation in the process of S9, when it is determined that there is an abnormality in the temperature sensor 2, the human body sensor 28, the gas leak sensor 5, and the smoke sensor 6 in the abnormality determination process (S8) (S9: Yes), An emergency call process for giving an alarm to a pre-registered contact such as the telephone 100 is executed (S16), and this management process ends. In addition, S
As a result of checking in the process of 10, if the series of processes of S2 to S9 is executed based on the response request command (S
10: Yes), the response data transmission process of transmitting the detection data to the requesting mobile phone (mobile phone 56 or the like) is executed (S15), and the management process is ended. In this management process, the data reading time is executed at intervals of a short time such as approximately every 10 seconds. Thus, when an abnormality occurs, the abnormality can be surely detected.

By the error processing (S14), the slave unit 2
If an error is determined to be 0, it is determined that the human body sensor 28 incorporated in the child device 20 has an abnormality. Therefore, even if the abnormality of the detection data does not actually occur, the emergency call process (S16). Is executed. As a result, the recipient of the data (the owner of the mobile phone 100 or the like) can know the occurrence of the error.

FIG. 4 is a flowchart of the abnormality determination process (S8) executed in the management process of FIG. The abnormality determination process (S8) is a process for comparing the detection data transmitted from the child device 20 with a standard value stored in the ROM 42 in advance and determining whether or not there is an abnormality in the detection data.

In this abnormality determination processing (S8), first, the header data of the received data (detection data transmitted from the handset 20) is read, and the identification number of the source handset of the data is set to the first to the 20th child. The machine memories 46f1 to 46f20 are referred to for confirmation (S21). This allows the parent device 40 to know which of the child devices 20 has received the detection data. Next, the first to twentieth slave memory 46 is associated with the identification number (of the received detection data).
The type of sensor stored in f1 to 46f20 is confirmed (S22). Then, the standard value corresponding to the confirmed sensor type, that is, the determination data is read from the ROM 42 (S
23), the read determination data is compared with the corresponding data in the received detection data (S2).
4).

The processes of S21 to S24 are executed for each one child device 20 (each detection data thereof). And S
If the slave unit 20 that is the target of the processes of 21 to S24 is the slave unit 20 for which the detection data has not been received, that is, the slave unit 20 that has been determined to be an error in the management process, the slave unit 20 is determined to have an abnormality. A determination is made (S25). After that, it is confirmed whether or not the determination is completed for all the slaves 20 to be connected (S26). As a result, if the determinations for all the slaves 20 are completed (S26: Yes), this The abnormality determination process ends. On the other hand, as a result of checking in the process of S26, if the determination for all the slaves 20 has not been completed (S26: No), the process proceeds to the process of S21 and the determination for all the slaves 20 ends. Until you do S
The processing from 21 to S26 is repeated.

FIG. 5 is a flowchart of the data conversion process executed in the slave unit 20. The data conversion process is performed by an analog sensor (sensor 2
This is a process of converting the analog detection data detected in 4) into digital detection data. This data conversion process is executed for each child device 20. Since each slave unit 20 is installed in each monitoring area as described above, analog data detected by the analog sensors 2 to 4 installed in the monitoring area can be converted into digital data in the vicinity thereof. it can.

In this data conversion process, first, the detected analog data is sampled every predetermined time (S3
1) Convert the sampled analog data into digital data (S32). Then, the information (sensor type) of the detection source sensor is added to the converted digital data (S33). Sensors 2 to 6 connected to the child device 20
28 is recognized by the MPU 21 by the position of the port to which the signal lines of the sensors 2 to 6 and 28 are connected. Cordless handset 20
In the above, the sensor information (sensor type) is stored in advance in the ROM 22 corresponding to each port. Therefore, the information of each sensor can be added to the sensors 2 to 6 and 28 connected to the child device 20.

After the processing of S33, the detection data to which the sensor information is added is written in a predetermined area of the RAM 23, the previously stored data is updated (S34), and this data conversion processing is terminated.

FIG. 6 is a flowchart of the detection data transmission process executed in the slave unit 20. The detection data transmission process is a process of transmitting the detection data stored in the predetermined area of the RAM 23 by the above-described data conversion process to the master device 40 based on the detection data request command transmitted from the master device 40.

In this detection data transmission process, first, it is confirmed whether or not a detection data request command with its own identification number is received (S41), and as a result of the confirmation, the detection with its own identification number is detected. If the data request command has not been received (S41: No), the detection data transmission process ends. On the other hand, as a result of the confirmation in the process of S41, if the detection data request command with its own identification number is received (S41: Yes), the detection data stored in the RAM 23 is written in the transmission memory 23a (S42), After that, in the detection data stored in the transmission memory 23a, the identification number (one of the numbers 1 to 20) of the child device and the parent device 4 of the transmission destination are included.
An identification number of 0 is added as header data (S4
3). Then, the detection data to which the header data is added is transmitted to the parent device 40 (S44), and this detection data transmission process is ended.

The slave unit 20 receives the data (command) transmitted from the master unit 40 through the first connector 26, but its own identification number is added to the received data (command). If not, the data (command)
Is output from the second connector 27 and the received data is passed through (the detection data transmission process is not executed). In addition, the data transmitted to the parent device 40 from another child device 20 connected to the child device 20 (on the opposite side of the parent device 40) is received from the second connector 27 and then from the first connector 26. Is output. That is, the data transmitted from the other child device 20 to the parent device 40 is also passed.

As described above, according to the house security system 1 of the above embodiment, the analog sensors 2 to
The analog data detected by 4 can be converted into digital data in the vicinity of the analog sensor, and the converted digital data can be transmitted to the master device 40.
Therefore, in the parent device 40, it is possible to determine whether or not there is an abnormality by using digital data with little data deterioration. In addition, since the child device 20 can be connected to the parent device 40 via another child device 20, the child device 2 is connected to the parent device 40 without being restricted by the number of connectors provided in the parent device 40.
0 can be connected. In addition, the slave unit 20 and the master unit 40
Since the connection to and is made by the wired line 35, the house security system 1 can be constructed at a lower cost than when the connection is made by wireless.

The present invention has been described above based on the first embodiment. However, the present invention is not limited to the first embodiment, and various improvements and modifications can be made without departing from the spirit of the present invention. It is easy to infer that this is possible.

For example, in the house security system 1 of the first embodiment described above, all the detection data detected by the child device 20 is configured to be transmitted to the same destination, but instead of this, detection is performed. Depending on the content of the data,
You may comprise so that it may transmit to a different destination. For example, if the detection data of the temperature sensor 2, the gas leak sensor 5, the smoke sensor 6, the human body sensor 28, etc., which require an emergency response in the event of an abnormality, is configured to be transmitted to the security company (PC 110), it is possible to detect the abnormality. When an urgent response is required due to occurrence, a specialist (security company) can promptly respond. In addition, the detection data normally transmitted at regular time is transmitted to the mobile phone 100 of the resident of the residence, and if there is an abnormality, the security company (P
It may be configured to send the data to C110).

Further, the house security system 1 of the first embodiment is configured to ensure the security when the resident is out, but instead of this, a home mode is provided and the resident (owner) ) May be configured to operate in the security mode (suitable when at home) even when () is at home. In such a case, only the selected monitoring area (room) or the selected sensor is operated (for example, the detection data from the human body sensor 28 is discarded, and a window sensor or a vibration sensor is provided to detect an intruder. ). According to this, an unnecessary alarm (erroneous alarm or malfunction) can be eliminated.

In the house security system 1 of the first embodiment, the abnormality is determined by the detection data output from the various sensors 2 to 6, 28. However, a video camera for detecting an image ( It may be provided together with the sensor) and the interior of the room may be monitored by the image captured by the video camera. According to this, the credibility of the detection data of the sensor can be known by observing the image from the video camera.

In addition, in the house security system 1 of the first embodiment described above, the operation at the time of power failure is not particularly mentioned, but the secondary battery and the solar power are controlled so that each device operates for a predetermined time or more even at the time of power failure. You may comprise so that the power supply at the time of a power failure may be ensured by a battery etc. A power failure monitoring circuit for monitoring the occurrence of power failure may be provided. When a power failure is detected by the power failure monitoring circuit, the fact (the occurrence of an abnormality) may be notified to the mobile phone 100 or the PC 110.

In addition, in the house security system 1 of the first embodiment, when an emergency call is made from the master device 40 (mobile phone 56), the cancellation is issued from the mobile phone 56 owned by the resident. You may cancel by inputting. This makes it possible to prevent the same alarm from being sent many times.

Further, the setting switch 29 is composed of the same number of switches as the number corresponding to the number of the child devices 20, and the identification number is given to the child device 20 by pressing the switch at a predetermined position. Alternatively, a dial-type switch may be used and an identification number may be given depending on the dial position. Further, a plurality of slide switches may be provided and the identification number may be given by combining the switch positions. Alternatively, a rewritable non-volatile memory may be provided in each slave device 20, and the identification number may be assigned to each slave device 20 by writing the identification number from the master device 40 to the memory.

In addition, in the management process, when an error is detected in the child device 20, the fact may be notified to the mobile phone 100 or the like by mail data.

[0108]

According to the house security system of the first aspect, the analog data regarding the security inside and outside the building detected by the analog sensor is converted into digital data by the relay device installed near the analog sensor. , The converted digital data,
It is transmitted to the management device via a wired line. That is, the analog data detected by the analog sensor is immediately converted into digital data when transmitted over a short distance in the form of analog data, and is transmitted to the management device in the form of digital data. Therefore, there is an effect that it is possible to suppress the deterioration of the signal due to the influence of noise during data transmission, and it is possible to easily restore even if the signal deteriorates. Therefore, even if the transmission distance of detection data is long, accurate detection data can be obtained, and even if the sensor is installed far away from the management device, high security based on accurate detection data is ensured. There is an effect that can be done. Further, since the detection data is transmitted to the management device through a wire line which is cheaper than the wireless line, there is an effect that the cost of the system can be reduced.

According to the house security system of the second aspect, in addition to the effect of the house security system of the first aspect, the relay device has one relay located on the management device side by the management device side connection means. The devices are connected, and one relay device is connected by the relay device side connection means provided separately from the management device side connection means. That is, another relay device can be connected to the management device via the relay device. Therefore, the number of relay devices directly connected to the management device can be reduced. Here, when the number of relay devices directly connected to the management device is small, for example, the number of connectors provided for connecting the relay device to the management device can be reduced. When a large number of connectors are provided in the management device (when a large number of relay devices are connected to the management device), the device configuration of the management device becomes large, but other relay devices are connected to the management device via the relay device. As a result, it is possible to avoid such an increase in the size of the device and to design the management device compactly.

Further, when the identification number given to the data received via the management device side connection means is the identification number of another relay device, the relay device outputs the data from the relay device side connection means. At the same time, the data received via the relay device side connection means is output from the management device side connection means.
In other words, the relay device simply passes data other than the data transmitted to its own relay device. Therefore, even if data is communicated between another relay device and the management device via the relay device, the control load on the relay device serving as the relay point is not increased.

According to the house security system of claim 3, in addition to the effect of the house security system of claim 1 or 2, the management device sequentially sends commands to the relay device. After the data communication with the relay device that has received the command is completed, the data communication is executed with the next relay device.
Therefore, even if data communication between another relay device and the management device is performed via the relay device, that is, even if data communication between the plurality of relay devices and the management device is performed in one data transmission path, This has the effect of avoiding data collision.
