It is characterized by.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

As shown in FIG. 1 to FIG. 2, the present invention provides a wireless pager, comprising: a signal receiver 10 for receiving a wireless call signal, a decoder 20 for decoding a received wireless call signal; The microprocessor 30 for processing the signal output from the decoder 20, the motor 41, the memory 42, the LCD 43, the LED 44, controlled by the microprocessor 30, A control processor 40 comprising a switch 45 and an oscillator 46, a timer 56 that counts the time when an emergency rescue signal code is received from the microprocessor 30, a Citiphone base station 60, and an RF. An RF interface unit 55 for transmitting and receiving a signal, an RF receiving circuit 53 and a high frequency amplifier 54 connected to the RF interface unit 55, respectively, and transmitting and receiving for switching transmission and reception by the microprocessor 30. RF transceiver unit consisting of the switching circuit 51 and the oscillator 52 ( 50).

In addition, the switch unit 45 includes a confirmation switch 4, a memory confirmation switch 5 and the emergency rescue switch (6).

When explaining the operation, the effect of the present invention is configured in this way as follows.

As shown in FIGS. 1 to 4, first, the microprocessor 30 determines whether the emergency rescue switch 6 has been operated in the switch unit 45, and transmits according to a program stored in the memory 42. FIG. Or enter standby mode.

In the standby mode, it is determined whether the radio call signal has been received by the signal receiving unit 10, and it is again determined whether the emergency switch 6 is operated, or the receiving mode is executed.

In the reception mode, it is determined whether the emergency call signal code is included in the radio call signal input to the microprocessor 30, and the transmission mode or the call execution mode is executed.

In the call execution mode, the control processor 40 is received by the signal receiver 10 through the antenna of the wireless pager 1 and then decoded by the decoder 2 according to the wireless call signal input to the microprocessor 30. By driving the motor 41 of), the person carrying the pager 1 is notified of the radio call. The wireless call signal input according to the operation of the confirmation switch 4 and the memory confirmation switch 5 of the switch unit 45 is displayed on the LCD 43 and the LED 44 in letters and numbers.

The transmission mode is executed when the emergency rescue switch 6 installed in the pager 1 is forcibly operated and when the emergency call signal code is included in the radio call signal. At this time, the wireless call reception function of the pager 1 is stopped by the microprocessor 30 and the mode is switched to the transmission mode.

In the transmission mode, the transmission / reception switching circuit 51 is set to the transmission / reception state, and the connection is established after the Citiphone base station 60 is identified through the RF receiving circuit 53, the high frequency amplifier 54, and the RF interface unit 55. Try. Subsequently, when connected to the base station 60 and connected to the telephone exchange electronic switch, after confirming the dial tone, the emergency call number stored in the memory 42 is automatically dialed to access the situation room. Next, after confirming the ringing tone and checking the communication state, if the intermittent sound is not detected, the RF interface unit modulates and amplifies the emergency rescue signal and the personal code stored in the memory 42, and then the RF interface unit. Wirelessly transmits to the Citiphone base station 60 via 55. The emergency rescue signal and the personal code transmitted to the Citiphone base station 60 by radio (RF) are transmitted to the situation room via the telephone exchange.

At this time, the intermittent sound is detected when the state of the line being transmitted, when it is dragged by the surrounding interference, or when the person carrying the wireless pager 1 is out of the call distance of the Citiphone, so that the call is stopped and the microprocessor ( The transmission mode is executed again in 30).

The emergency rescue signal and the personal code being transmitted are repeatedly counted by the timer 56 and are repeatedly executed until the power is completely consumed with a three-minute transmission state and a three-minute idle state. . At this time, the wireless pager 1 can receive a wireless call in the idle state, and when the emergency rescue signal code is received by the wireless call, the microprocessor 30 switches to the transmission mode regardless of the time and resumes the transmission mode. Run In this case, the frequency band received by the signal receiving unit 10 and the frequency band received through the RF interface unit 55 and the RF receiving circuit 53 are different from each other.

In addition, the transmission of the emergency rescue signal and personal code is read in the operation room to track the movement route of the person carrying the wireless pager 1, and at the same time, the police station, police box and the patrol car closest to the city telephone base 60 are instructed. The caller tracks the caller who sent the emergency signal.

As described above, when a person carrying a wireless pager wants to notify of an emergency or emergency situation, by forcibly operating the emergency rescue switch of the wireless pager, the emergency room rescue device is sent to the situation room via the Citiphone base station and the telephone exchange's electronic switchboard. A signal and a personal code can be transmitted, and a person carrying a wireless pager can be called using a call signal including an emergency rescue signal. Therefore, by using the location or identity of the person who sent the emergency rescue signal or the radio call signal, the location and identity of the person who is requested for emergency rescue can be determined to obtain the lives of the person who sent the emergency rescue or the person who is requested for emergency rescue. It works.
