The present invention relates to a system for wireless emergency telephone calls and self-diagnosis, and more particularly, to prevent modification of data having various types of information transmitted and received between wireless emergency telephones and emergency centers, and to speed up the transmission and reception of data having various types of information. The present invention relates to a system for wireless emergency telephone calls and self-diagnosis that can be increased.

1 is a configuration diagram showing a system for a conventional wireless emergency telephone call and self-diagnosis. When the handset of the wireless emergency telephone 119 is lifted, the wireless emergency telephone 119 is an emergency center (situation room) 122 with a guide message. Calls the CO line number and the ID number for ID identification.

The ring signal via the mobile communication base station 120 is transmitted to the key phone control device 123 in the emergency center 122 through the PSTN 121 (Public Switched Telephone Network). The trunk line receiving card 124 in the key phone control device 123 makes an automatic response to the incoming call and then calls the extension number for ID classification.

As the extension number is called by the CO line receiving card 124, the number of the wireless emergency call 119 calling the reception desk phone 128 is SLC (Signalling Link Control) and CO line receiving card 125 (or ID) for identification. ID detection controller) and ringing the reception desk phone 128 through the keyphone extension card 126, and the number of the divided wireless emergency call 119 is displayed on the LCD and DSS box of the reception desk phone 128 (Decision Support). You can check the number and location of the wireless emergency call displayed on the lamp of the system box or displayed on the computer. In addition, when the operator lifts the handset of the reception desk phone 128, the emergency center 122 and the wireless emergency call 119 are connected to make a call, and the contents of the call are recorded in the recording device 129.

On the contrary, when the reception desk phone 128 dials the number of the corresponding wireless emergency call 1119, the call signal is transmitted to the PSTN 121 through the key phone controller 123. The call signal through the PSTN 121 calls the corresponding wireless emergency call 119 via the mobile communication base station 120. Subsequently, when the user hears the buzzer of the wireless emergency call 119 and the user lifts the handset of the wireless emergency call 119, a call is made between the emergency center 122 and the wireless emergency call 119.

When the call is made by calling the emergency center 122 in the wireless emergency call 119, the wireless emergency call classification and call history through the keyphone extension card 123 or the SLC for ID identification and the CO line 125 is RS232. By being transmitted to the emergency call maintenance computer 131 through the number, schedule, location time, call time of the wireless emergency call is displayed and stored on the screen. Here, the personal information of the caller and the contents of the call during the call may be edited, stored, and outputted as necessary.

In addition, the ring signal from the emergency telephone maintenance computer 131 in the emergency center 122 is transmitted through the wired self-diagnosis control unit 130 during the initial installation to call the wireless emergency telephone 119. When the ring emergency signal 119 detects and responds to a ring signal, sensors, circuit conditions, and the like in the wireless emergency call 119 are transmitted and received by the DTMF (Dual Tone Multi Frequency) method to the DTMF. It transmits the battery and solar cell status, and transmits the data to the emergency telephone maintenance computer 131 by RS232 communication by the wired self-diagnostic control unit 130 to save or output to the screen.

The operation of the wireless emergency call will be described in detail with reference to FIG. 2. When the handset unit 103 of the wireless emergency call is maintained while the standby state is maintained, the signals of the switches are transferred through the switch input circuit 104. Input to 105, the microprocessor 105 recognizes the use of a wireless emergency telephone.

Subsequently, the microprocessor 105 outputs the voice message of the memory 101 to the handset unit 103 through the voice message control circuit 102 as a guide message, and at the same time, automatically outputs the emergency message through the DTMF transmission circuit 113. Since the telephone number of the reception desk phone in the center (situation room) is transmitted and the reception desk phone is called through the voice level adjusting circuit 112 and the mobile radio telephone 116, the emergency center and the wireless emergency call are made.

Here, each wireless emergency telephone is provided with a solar cell 106 and a battery 108, the battery charge and discharge at a level that is charged and discharged in the microprocessor 105 by the voltage detection circuit 109 and the temperature sensor 117. The control circuit 107 is appropriately supplied to the solar cell 106 and the battery 108, and power is supplied to various circuits and mobile radiotelephones 116 through the power supply circuit 110.

In addition, when there is a call for self-diagnosis in the emergency telephone maintenance computer in the emergency center, the ring signal by the call is transmitted to the microprocessor 105 through the mobile radio telephone 116 and the ring detection circuit 115, 7 If the handset unit 103 is not lifted for 8 times, the microprocessor 105 recognizes that a call for self-diagnosis has been made.

Subsequently, the microprocessor 105 transmits the diagnostic data such as the voltage and the control state to the mobile radiotelephone 116 through the DTMF transmission circuit 113 and the voice level control circuit 112 as DTMF signals. By reporting to the system, DTMF signals such as voltage and control status are transmitted to the emergency telephone maintenance computer, collected, displayed, stored, and outputted when necessary.

The principle of the conventional DTMF (Dual Tone Multi Frequency) method is that the DTMF (697 Hz to 1,633 Hz), that is, the diagnostic report contents are transmitted to the voice region (300 Hz to 3,300 Hz) through the DTMF transmission circuit of the internal controller in the wireless emergency call. The signal corresponding to the dial button of a general telephone is transmitted to the talk (microphone) circuit of the RF module (cell phone).

Subsequently, the RF module (cell phone) converts the signal for the diagnostic report into a digital signal and restores the voice signal through the switch of the PSTN via the CDMA of the mobile communication company, and wires it to the emergency center (situation room). To pass). Then, the emergency center (situation room) receives the diagnostic report through the DTMF receiving circuit, restores it, and processes it on the emergency telephone maintenance computer.

However, during the process of converting the DTMF signal via the talk (microphone) circuit of the RF module (cell phone) into a digital signal, the waveform of the DTMF signal is deformed, or the DTMF signal through the switch of the PSTN is restored to restore the DTMF signal to the emergency center. There is a drawback that the waveform of the DTMF signal is deformed in the process of being transmitted to the (situation room).

In addition, the type of data that can be reported at one time is limited to a certain number (16), so that a large amount of data is transmitted in a large amount of time, and there is a drawback that there is a delay time of at least 200 ms after one transmission.

The present invention is to solve the above-mentioned drawbacks, and to prevent the modification of data having various types of information transmitted and received between the wireless emergency call and the emergency center, and to increase the transmission and reception speed of data having various information The objective is to provide a system for emergency telephone calls and self-diagnosis.
