The present invention relates to a reception detecting device for detecting an incoming state in a portable wireless communication system, and more particularly, to an apparatus for detecting an incoming signal received wirelessly using vibration of a solenoid.

In the conventional portable wireless communication system, when an incoming signal is wirelessly received from a receiving device, the user may be vibrated using a motor to inform the user or to make a buzzer to detect the user.

As described above, since the vibration is detected by the rotation of the motor, the incoming signal is detected. Therefore, power is continuously supplied to the motor until the call mode is switched, thereby increasing the power consumption of the battery.

It is therefore an object of the present invention to provide an apparatus for solving the above problems.

Another object of the present invention is to provide an apparatus for detecting an incoming signal wirelessly received in a portable wireless communication system using vibration of a solenoid.

The present invention for achieving the above object is a control means for generating a switching control signal for performing an alarm function according to the mode by analyzing the received data, buzzer sound generating means for generating a buzz sound in the alert mode, the solenoid in the silent mode Selecting the buzzer sound or the voltage by inputting a voltage converting means for supplying power for driving the power supply, a buzzer sound generated by the buzzer sound generating means and power supplied from the voltage converting means; A mode selecting means for switching output, a pulse generating means for generating and outputting a predetermined number of pulses by receiving the power output selected in the silent mode by the mode selecting means, and a vibrator at high speed by the pulse generated by the pulse generating means. Consists of solenoids that cause vibration by reciprocating And a gong.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a portable wireless communication system according to the present invention, wherein the RF receiver 10 receives an RF signal received through an antenna ANT, and amplifies, converts frequency, filters the received RF signal. Demodulation, waveform shaping and conversion to binary data are output. The decoder 20 receives the output of the RF receiver 10, decodes the received binary data, and outputs the decoded binary data. The controller 30 analyzes the data received from the decoder 20 to generate a switching control signal for performing an alarm function and to control the overall operation of the system. The buzzer sound generator 40 generates a buzzer sound in the Alert mode. The voltage converter 50 supplies power for driving the solenoid in the silent mode. The mode selector 60 inputs the buzzer sound generated by the buzzer sound generator 40 and the power supplied from the solenoid power supply device 50 to switch and output the switching signal according to the control signal of the controller 30. The speaker 70 transmits the buzzer sound selected and output in the alert mode by the mode selector 60. The pulse generator 80 receives a power output selected in the silent mode from the mode selector 60 to generate a pulse of a predetermined period. The solenoid 90 causes vibration by reciprocating the vibrator at high speed by the pulse generated by the pulse generator 80.

In the above configuration, the control unit 30 is a 4-bit one-chip microprocessor, in which RAM and ROM are embedded.

2 is a flowchart of detecting an incoming signal by the solenoid according to the present invention, and FIG. 3 is a configuration diagram of the solenoid 90 in FIG.

Hereinafter, an operation of an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3.

The RF receiver 10 receiving the RF signal input through the antenna ANT includes an amplifying means, a frequency converting means, a filtering means, a demodulating means and a waveform shaping means to generate waveform-shaped data in binary form. Then, the decoder 20 receiving the output of the RF receiver 10 detects the synchronization and decodes the received message. Thereafter, the controller 30 compares the data output from the decoder unit 20 with its own address to check whether the received message is its own message. At this time, in case of the message of the self address, the received message is stored in the internal RAM and an alarm function is performed. The controller 30 varies the alarm type according to the designated mode. In the case of the Alert mode, the controller 30 controls the mode selector 60 to transmit the buzzer sound generated by the buzzer sound generator 40 to the speaker 70. In the silent mode, the power is supplied to the pulse generator 80 by controlling the mode selector 60. At this time, in the silent mode, the control unit 30 controls the mode selection unit 60 and the pulse wave generator 80 supplied with power from the voltage conversion unit 50 generates and outputs a pulse of a predetermined period. The pulse of a predetermined period output from the pulse generator 80 drives the solenoid 90 as shown in FIG. 3 to cause the vibrator 94 to reciprocate at high speed to cause vibration to detect an incoming state.

The above-described process will be described with reference to the flowchart of FIG. 2. When the power is initially turned on or an initialization command is generated, the controller 30 performs an initialization function in step 201. In the initialization process, the decoder 20 is initialized and the magnetic address stored in the memory is stored in the RAM. After performing the initialization process, in step 202, it is in an idle state, and in step 203, it is checked whether a signaling tone is received. If the signaling tone is received at step 204, it checks whether it is a self address message in step 204, terminates the program if it is not a self address, and proceeds to step 205 if it is a self address. In this case, in step 206, the controller 30 controls the mode selector 60 to transmit the buzzer sound generated by the buzzer generator 40 through the speaker 70. However, if the silent mode in step 205 proceeds to step 207, the controller 30 controls the mode selector 60 to supply the voltage generated by the voltage converter 50 to the pulse generator 80. do. When the voltage of the voltage converter 50 is applied to the pulse generator 80, the pulse generator 80 generates a pulse of a predetermined period and applies it to the solenoid 90 as shown in FIG. As a result, the solenoid 90 inputs the pulse to the coil 91 of FIG. 3 and the vibrator 94 vibrates by the reciprocating motion as the spring 93 is pressed to generate an alarm.

As described above, by detecting the alarm of the incoming signal received wirelessly in the portable wireless communication system using the vibration of the solenoid, it is possible to extend the life of the battery by reducing the power consumption than when the alarm occurs using the motor There is an advantage.
