The effect of this invention is demonstrated to the working example.

This invention communication controller 10 is installed next to the living room telephone 100. Connect the modular jack of the telephone line (TEL) to the IN terminal of the communication controller 10, connect the lead wire of the telephone 100 to the OUT terminal of the communication controller, and supply DC driving power to the POWER terminal of the communication controller 10. do. The driving power is supplied to the work controller 20 including the fire extinguisher 22. In FIG. 1, the job controller 20 is a terminal device for remotely reporting the state of the fire extinguisher 22 and the occurrence of a fire. Reference numeral 120 is a gas circuit breaker, 200 is a gas band.

A user dials the telephone number of the telephone 100 of his home from a remote telephone with a mobile phone. The ring signal is transmitted to the communication microcomputer 11 of the communication controller 10 through the telephone line 12.

I. In the ring signal detection process, the communication microcomputer 11 counts the number of ring signals while detecting a ring signal of a telephone line. The hook off signal of the telephone 100 was detected in the third ring signal. In this case, the communication microcomputer 11 regards the call mode for the telephone 100 and stops counting the number of ring signals and proceeds to the call disconnection detection process.

II. In the disconnection detection process, the communication microcomputer 11 provides the signal of the telephone line 12 to the signal decoder 14 and waits for the signal decoder to return the disconnection signal. In this process, when the call disconnection signal is received from the signal decoder 14, the communication microcomputer 11 considers that the call is over and transfers the initial signal to the ring signal detection process.

The ring signal was again transmitted to the communication microcomputer 11 through the telephone line 12. The communication microcomputer 11 counts the number of ring signals while detecting the ring signal in the ring signal detection process. The ring signal has reached the set number. This setting number is 5-9. Preferred setting number is seven. When the number of ring signals reaches the set number, the communication microcomputer 11 shifts to call control. In call control, the communication microcomputer 11 controls the signal decoder 14, the voice chip 15, and the switch 16 to output the hook-off signal.

When the call state is established, the communication microcomputer 11 proceeds to the caller identification process to confirm whether the remote accessor is a registered user.

III. In the caller identification process, the communication microcom 11 controls the voice chip 15, the switch 16, and the voice output unit 17 to transmit a voice message "Enter a four-digit password" to the telephone line 12. To the audio output unit 17. The voice signal transmitted to the voice output unit 17 with the switch 16 turned on is reproduced by the speaker included in the voice output unit 17. The voice signal sent to the telephone line 12 is reproduced by the handset of the remote user. After transmitting this voice signal, the communication microcomputer 11 detects a password dial tone signal on the telephone line 12.

IV. The password detection process is to send a signal received from the telephone line 12 to the signal decoder 14 and to receive the decrypted number from the signal decoder. If no dial tone signal is detected after 10 seconds, the voice message is sent again and waits 10 seconds. If there is no password input after 10 seconds, the communication microcomputer 11 proceeds to the hangup process.

V. The hang up process is to control the signal decoder 14 and the switch 16 to send a hook-on signal to the telephone line 12. If the call is disconnected, the process proceeds to the ring signal detection process.

If the digit value returned from the signal decoder 14 during the password detection process is four digits, the communication microcom 11 compares the four digits with the user password registered in the memory 18. If the comparison result matches the registration number, the communication micom 11 regards the remote accessor as a registered accessor and calls the control of the terminal device status reporting process and the control of the terminal device operation process, and when these transition processes are completed, the communication microcom 11 Calls the hang up process to hang up the call and proceed to ring signal detection. If the password is different from the registered password in the password comparison step, the communication microcomputer 11 calls the call termination process to hang up the telephone and proceed to the initial ring signal detection process.

VI. The status reporting process is called in the call state. In the status reporting process, the terminal device communication microcomputer 11 controls the power supply 19 to supply power to the transmitter TXc, and code a status report request command coded with an encoding key to the transmitter TXc and includes the terminal device identification code. To pass. The transmitter TXc transmits a status report request command Tx cmd from the antenna. In the embodiment, the communication frequency band employed in the transmitter and the receiver is an AM communication channel of 311Mz 30mw, which is a short range communication frequency band.

The operation controller operation process is called when the communication microcomputer 11 obtains a dial tone signal from the telephone line 12 and requests the signal decoder 14 to receive a caller's terminal device operation request using a digit code.

VII. In the operation controller operation process, the communication microcom 11 controls the power supply 19 to supply power to the transmitter TXc and transmits an encoded operation request command together with the terminal device identification code to the transmitter TXc. The transmitter TXc transmits an operation request command Tx cmd from the antenna.

The receiver RXw supplied with the power of the job controller 20 receives the encoded operation request command Rx cmd and provides it to the job micom 21. The work micom 21 decrypts the received command Rx cmd with the stored key to distinguish the terminal device identification code from the work instruction command. If the distinguished terminal device identification code matches the magnetic code stored in the memory, the work micom 21 drives and controls the terminal device driver, the fire extinguisher 22, in response to the distinguished work order command, and then checks the state of the fire extinguisher 22. do.

The work micom 21 codes the obtained state information together with the code of the communication controller. The work micom 21 controls the power supply 29 to supply driving power to the transmitter TXw and to transmit coded operation report data Tx dta from the antenna.

The receiver RXc supplied with the power of the communication controller 10 receives the operation report data Rx data and provides the same to the communication microcomputer 11. The communication microcomputer 11 decrypts the key for storing the operation report data. The communication microcomputer 11 identifies the decrypted data with the communication controller identification code and the report data. The communication microcomputer 11 makes a voice report when the identified communication controller identification code matches its own code.

VIII. In the voice report, the communication microcom 11 controls the voice chip 15, the switch 16, and the voice output unit 17, and selects a message corresponding to the report data from the voice message prepared on the voice chip, thereby making a telephone line 12 ) And the speaker.

The operation report follows the example of the status report (VII) above.

The job controller 20 may drive an alarm device such as a status display unit 28, a direct control switch 24, and an added buzzer in addition to the radio response function.

This invention control is demonstrated as an example.

VIII. During the status report request processing, the receiver RXw supplied with the power of the job controller 20 receives the encoded status report request command Rx cmd and provides it to the work micom 21. The work micom 21 decrypts the received command Rx cmd with a decryption key. The task micom 21 divides the decrypted command into a task controller identification code and a command. The work micom 21 checks the state of the fire extinguisher 22 in response to the decrypted command if the work controller identification code matches its code stored in the memory.

IX. During the state test of the fire extinguisher 22, the working microcomputer 21 reads the pressure signal pvs of the fire extinguisher from the pressure sensor 22b, compares the program with the stored pressure data, and considers the normal state if it is within the normal pressure range. Assign the value '1' to the variable. If it is not in the correct state, it assigns '0' to PVS variable. The work micom 21 receives the status signal nsps from the disconnection detection unit 23b connected to the drive coil of the fire extinguisher valve 22a and the drive motor, and assigns a value of '1' to the NSPS variable if it is not disconnected. If disconnected, assign '0' to NSPS variable.

X. In the process of transmitting the status information, the work micom 21 encodes the obtained status information (eg, PVS and NSPS) together with the identification code of the communication controller 10. The work micom 21 controls the power supply 29 to supply driving power to the transmitter TXw and to transmit coded status report data Tx dta from the antenna.

XI. In the process of receiving status information, the receiver RXc supplied with the power of the communication controller 10 receives the status report data Rx data and provides it to the communication microcomputer 11. The communication microcomputer 11 decrypts the status report data with the stored decryption key (eg, the PVS value and the NSPS value).

XII. During the voice report during a call, the communication microcom 11 selects a message stored in the voice chip 15 based on the decrypted data and reports the status. The status report is that the communication microcomputer controls the voice chip 15, the switch 16, and the voice output unit 17 to output the selected voice message to the phone line 12 and the speaker.

An example of the voice message stored in the voice chip is "Fire extinguisher can operate properly" for "PVS == 1", "Warning, fire extinguisher has failed", "for PVS == 0" The fire extinguisher is ready for NSPS == 1 ". For" NSPS == 0 "," Warning, the extinguisher driver is faulty ".

The job controller 20 controls the gas valve 120 to shut off the gas when the gas detection sensor 26 detects a gas leak, drives the fan 27 to exhaust the gas, and remotely monitors the event situation. Report to

XIII. In the process of detecting turbid air, when the work micom 21 obtains the detection signal gasi from the turbid air detection sensor 26, '1' is substituted into the variable GASI.

Through the state information transmitting process (X) and the state information receiving process (XI), the information of "GASI == 1" is transmitted to the communication micom to the communication micom 11 of the communication control unit 10,

The gas is locked by the gas (valve) fuse 120, and the fan driving driver 27a is controlled to drive the fan 27.

XIV. In the ventilation process, the working microcomputer 21 checks the gas detection signal gasi of the gas sensor, and if there is no gas detection, stops the operation of the fan 27 and substitutes '0' into the variable GASI.

The information of "GASI == 0" is transmitted to the communication micom 11 of the communication controller 10 through the state information transmitting process and the state information receiving process.

When the communication microcom 11 receives the information of "GASI == 1" from the work microcom 21,

The situation is reported to the remote user through the dialing process (XV) and the in-call voice reporting process (XII). The voice report says: "A turbid air is detected and the gas valve is shut off and the fan is running." As this progresses, the remote user will notice that turbid air, such as smoke and leaking gas, is being generated and ventilated at home.

When the communication microcom 11 receives the information of "GASI == 0" from the work microcom 21,

The situation is reported to the remote user through the dialing process (XV) and the in-call voice reporting process (XII). The voice report said, "It is safe by exhausting turbid air and closing the gas valve." As this process proceeds, the remote user will notice that the indoor air, whose gas has become turbid with leakage, smoke, etc., is exhausted from home and the indoor air has returned to normal.

XV. The dialing process is performed by the communication microcom 11 tone signal generator that stores the phone number stored in the priority of one or more remote phone numbers (one or more mobile phone numbers and one or more remote landline phone numbers) stored by the program. 14b, the tone signal generator 14b sends the telephone number to the telephone line 12 as a dial tone signal, and the communication microcom 11 decodes the hook-off signal of the call receiver's telephone. If detected in, it is regarded as a call state and proceeds with the voice report during the call. If the call fails, the communication micom will try to make a call with the phone number stored in the next order. If there is only one stored phone number, try using this phone number repeatedly to make a call. When the call is over, the communication microcomputer controls the process of hanging up.

XVI. When the working microcom 21 obtains the temperature (130 ° C.) signal tsc, which is regarded as a fire, in the heat detection sensor 25, the working microcom 21 substitutes '1' into the variable TSC.

Through the status information transmission process (X), the fire occurrence information "TSC == 1" is transmitted to the communication microcomputer 11 and the fire extinguishing process is performed.

XVII. In the extinguishing process, the work micom 21 controls the gas valve 120 to be locked, and controls the switch 23a with the control signal swc to drive the extinguishing valve 22a driving motor 23 and to extinguish the extinguishing agent horn 22c. Eject from When working microcom fires the fire extinguishing signal of 130 degrees C or less from the heat sensor, the motor 23 controls the motor 23 to close the fire extinguisher valve 22a, inserts '0' into the variable TSC, and transmits the status information transmission process (III). The evolution information "TSC == 0" is transmitted to the communication microcomputer 11.

When the communication microcomputer 11 receives the information of the fire occurrence information "TSC == 1", it decodes the signal and makes a call to the designated remote user through the dialing process (XV), and when the call is in the state of voice communication during the call (XII). ) And send a voice report to the telephone line: "Fire has occurred and the gas valve is closed and is under fire."

When the communication microcomputer 11 receives the information of the extinguishing information "TSC == 0", it decodes the signal and makes a call to the designated remote user through the dialing process (VIII), and when the call is in the state of voice communication during the call (V) Sends a voice report "Fire has evolved" to the telephone line.

According to the present invention, when the automatic fire extinguishing device is connected to a remote user through a telephone line, a two-way wireless automatic fire extinguishing device for connecting the terminal space from the end of the telephone line to the fire extinguisher by two-way radio, and reports the status of the fire extinguisher wirelessly When a gas leak, smoke, fire extinguishment or ventilation is required, the ventilation fan is reported to the remote user through a telephone line, and when the fire is detected, the fire extinguisher is activated. Provides a two-way wireless automatic fire extinguishing system that reports the status of generation and operation of fire extinguishers.
