1 is a block diagram of a wireless telephone according to a preferred embodiment of the present invention.

The controller 111 controls the overall operation of the radiotelephone. In particular, the controller 111 checks the number of charges of the rechargeable battery according to the present invention and controls the transmission of a replacement request signal or a replacement request message of the rechargeable battery when the battery is charged for a predetermined number of times. The duplexer 112 outputs a signal received from the antenna ANT to the receiver 115 and a signal received from the transmitter 113 to the antenna ANT. The transmitter 113 synthesizes the electrical voice signal received from the modem 116 and the carrier signal received from the frequency synthesizer 114 under the control of the controller 111 and outputs the synthesized signal to the duplexer 112. The frequency synthesizing unit 114 generates a signal for removing the receiving carrier frequency under the control of the control unit 111 and outputs the signal to the receiving unit 115, and generates and outputs a transmission carrier frequency to the transmitting unit 113. The receiver 115 synthesizes the signal received from the duplexer 112 and the signal received from the frequency synthesizer 114 under the control of the controller 111 and outputs the signal to the modem 116. The modem 116 generates a signal necessary for dialing under the control of the controller 111 and outputs the signal to the transmitter 113 or the voice signal received from the microphone MIC to the transmitter 113, and outputs the signal received from the receiver 115 to the speaker SPK. The audible sound is output through. The display unit 117 displays the state of the radiotelephone and the number of charges of the rechargeable battery according to the present invention. The key input unit 118 generates a key input signal corresponding to a key pressed by the user and outputs the key input signal to the controller 111. The memory unit 119 is divided into a program memory for storing a program necessary for the control of the control unit 111 and a data memory for storing data generated during the control operation.

Reference numeral 200 illustrates a connection diagram of a rechargeable battery that senses charging and supplies power according to the present invention. The charging terminal is connected to the charging sensing terminal A of the controller 111 through the resistor R1 for voltage distribution, and the charging terminal is grounded through the resistor R2 for voltage distribution. In addition, the charging terminal is connected to the positive terminal (+) of the rechargeable battery 150 through the reverse current prevention diode D1, and power is applied to each part of the wireless telephone to the positive terminal (+) of the rechargeable battery 150. Meanwhile, the negative terminal (-) of the rechargeable battery 150 is grounded through the charging ground terminal.

Accordingly, the rechargeable battery 150 is charged through the charging stage, and the charging sensing stage A may counter the number of charges of the rechargeable battery.

2 is a control flowchart of counting the number of charges according to a preferred embodiment of the present invention.

Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 2.

The control unit 111 maintains the standby state in step 200, and proceeds to step 202 to check whether a charging signal is applied from the charge detecting terminal A. FIG. The controller 111 proceeds to step 204 when the charging signal is applied, and proceeds to step 200 when the charging application signal is not applied. When the controller 111 proceeds from step 202 to step 204, the controller 111 proceeds to the charging mode. In this case, the charging mode means that power is not supplied by the rechargeable battery 150 but is supplied through a charging application stage, and maintains a reception and transmission standby state. In addition, when the controller 111 proceeds from step 204 to step 206, the control unit 111 checks whether a charge release signal is received through the heavy stop detector A. FIG. Here, the charge release signal refers to a state in which power is not applied to the heavy detection stage A. Accordingly, the control unit 111 proceeds to step 208 when the charge release signal is applied, and proceeds to step 204 when the charge release signal is not applied. When the charge release signal is received and the controller 111 proceeds to step 208, the controller 111 increases and stores the charge counter value stored in the memory unit 119 by one. The controller 111 checks whether the incremented counter value is greater than or equal to a preset value when storage is terminated in step 208. The controller 111 proceeds to step 212 when the test result is greater than or equal to the set value and ends when the control value is less than the set value. When the controller 111 proceeds from step 210 to step 212, the control unit 111 reads out a voice message stored in the memory unit 119 or data corresponding to the charge battery replacement request sound and outputs the audible sound through the speaker SPK. Here you can output the voice message "Replace the rechargeable battery with a new one". You can also output data in a specific beep format.

When the controller 111 proceeds from step 212 to step 214, the controller 111 checks whether the stop key for outputting the request sound according to the replacement of the rechargeable battery is input from the key input unit 118. The control unit 111 terminates when the stop key is input as a result of the test and proceeds to step 216 when the stop key is not input. When the controller 111 proceeds from step 214 to step 216, the controller 111 checks whether a set time due to the interruption of the request for replacing the rechargeable battery has elapsed. The control unit 111 ends when the test result set time has elapsed and proceeds to step 212 when the set time has not elapsed.

3 is a flowchart illustrating counter reset and counter display according to an exemplary embodiment of the present invention.

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

The control unit 111 maintains the standby state in step 300 and proceeds to step 302 to check whether a counter input key from the key input unit is a counter display key. The control unit 111 proceeds to step 304 when the check result counter display key is input, and proceeds to step 314 when the counter display key is not input. When the controller 111 proceeds to step 304 in step 302, the controller 111 displays the counted number on the display unit 117 and proceeds to step 306. In step 306, the controller 111 checks whether the Shosh setting time of the counter number displayed on the display unit 117 has elapsed. The controller 111 proceeds to step 308 when the inspection result display setting time has elapsed and proceeds to step 310 when the display setting time has not elapsed. When the controller 111 proceeds from step 306 to step 308, the control unit 111 releases the display of the counter number displayed on the display unit 117 and ends.

Meanwhile, when the controller 111 proceeds from step 306 to step 310, the controller 111 checks whether the reset key of the counter is input from the key input unit 117. The controller 111 proceeds to step 312 when the counter reset car is input, and proceeds to step 304 when the counter reset key is not input. When the counter reset key is input in step 310 and the process proceeds to step 312, the control unit 111 resets the counter value stored in the memory unit 119, and stores the counter value in the memory unit 119.

Therefore, the counter value can be counted again from the beginning when the rechargeable battery is replaced through the above process.

As described above, the counter value is increased every time the wireless telephone is charged and the counter value is increased by comparing the increased counter value and notifying the user when the counter value is higher than the set value. In addition, by resetting the counter value, there is an advantage in that the user can continuously know the replacement time of the rechargeable battery by performing a counter again when the rechargeable battery is replaced.
