The distance detector system is based on the infrared signal and the light sensor, and determines whether the human body is close according to the infrared signal reflection condition and the intensity of the light. When the human body approaches, the mobile communication device reduces the strength of the transmitted signal. However, if a distance detector is used, there must be a dedicated component and circuit layout inside the mobile communication device, which increases the manufacturing cost. At the same time, the distance detector can only detect the proximity of a single face, and the human body may not be detected if it is approached from different faces. To solve this problem, an additional distance detector is added, but the internals of the mobile communication device must have a more complicated circuit layout. In view of this, it is necessary to invent a new mobile communication device and adjust the 201228431 method to solve the lack of prior art. SUMMARY OF THE INVENTION The main purpose of this month is to provide a mobile communication device having the effect of automatically adjusting the energy of the wireless communication signal according to the load.

At least—the antenna core transmits wireless communication. The power amplifier is electrically connected to the antenna to receive or transmit wireless. Set the database to store the settings. _ The circuit system is electrically connected to the power generator and the setting database, and the mobile communication device is used to detect the mobile communication device: and the load is changed according to the setting database to determine whether the load change is sighed or not. The control circuit is electrically connected to the detection circuit, wherein the control circuit is based on the shutdown result, and the mosquito is controlled by a low-salt transmission, and (4) the energy of the Wei number. The difficult method of the present day motion rail device is used for mobile communication. The swaying communication device transmits the wireless communication signal via at least the antenna, and the y 1 touches or transmits the wireless unique signal. The method includes the following steps: transmitting a wireless communication signal via at least an antenna; detecting a load change inside the line communication device; determining whether the load change exceeds a threshold of 201228431 to generate a determination result; and determining according to the determination result Whether a control signal is output to reduce the energy of the wireless communication signal transmitted. The above and other objects, features, and advantages of the present invention will become more apparent from the claims. Please refer to FIG. 1 for the architecture of the mobile communication device of the present invention. The mobile communication device 10 of the present invention may be a mobile phone, a personal digital assistant (PDA), a notebook computer, a computer, but the present invention. It is not limited to the devices listed above. ~ ^ The device 10 has the ability to transmit wireless communication signals, and can adjust the electromagnetic wave strength of the wireless communication signal through the distance between the human body. The second antenna unit includes an antenna module 20, a power amplifier 30, a detection power setting database 50, a control circuit 60, and an analog digital converter u. The antenna module 20 can have a single antenna or a plurality of antennas. (The first antenna 21 and the second antenna 22 shown) are used to transmit various types of frequency wireless communication signals. The antenna module 20 has the type or number of antennas of the mobile communication device 10, The invention is not based on the fact that the rate amplifier 30 is formed by a hard body or a firmware with a hardware structure: the power antenna module 20 is electrically connected to receive or transmit the wireless communication signal and the rate amplifier 30 can be used. Linearly enlarge or reduce the power without '1 force' as needed. •..., 矾Signal detection circuit 40 is formed by software with hardware architecture or firmware with hard 201228431 body structure, and with power amplifier 30 The connection is used to detect the state change of the power amplifier 30, thereby determining whether there is a change in the load inside the mobile communication device 10. When the load inside the mobile communication device 10 changes, it represents the outside world. The change of the environment, for example, the head or the hand of the human body is close to the mobile communication device 10. Therefore, the detecting circuit 40 can determine whether to adjust the transmission power of the wireless communication signal according to the state of the power amplifier 30. The detection process of the detecting circuit 40 A detailed description will be given later, so it will not be described here. The setting database 50 is a hardware structure for storing preset setting values. The detecting circuit 40 is based on the preset value of the setting. A determination result is generated to further determine whether the internal circuit of the mobile communication device 10 needs to be adjusted. The control circuit 60 is formed by using a hardware with a hardware structure or a firmware and a hardware structure, and is electrically connected to the detection circuit 40. The detection circuit 40 generates a determination result when the detection circuit 40 detects that the state change of the power amplifier 30 exceeds a preset value, and the control circuit 60 outputs a control signal according to the determination result to reduce the energy of the wireless communication signal. The way to reduce the energy of the wireless communication signal will be described in detail later, so it will not be described here. In addition to the above components, the mobile communication The analog digital converter 11 must also include an analog digital converter 11. The analog digital converter 11 is formed by a hardware structure and is electrically connected to the detecting circuit 40 and the control circuit 60. The analog digital converter 11 is used to detect the circuit 40. The output analog signal is converted into a digital signal of the control circuit 60 to control the control circuit 60. Since the analog digital converter 11 or the mechanism of analog signal and digital signal conversion has been widely used in various electronic devices, and is not the present invention The key point is that the conversion mode will not be described in 201228431. Next, please refer to FIG. 2 and FIG. 3 for related diagrams of the first embodiment of the mobile communication device 10, wherein FIG. 2 is the first embodiment of the mobile communication device of the present invention. FIG. 3 is a circuit diagram of a first embodiment of a mobile communication device according to the present invention. In the first embodiment of the present invention, the detection circuit 40 is a power detection module 41, and the setting database 50 stores a power setting value 51. The transmit power detected by the power detection module 41 is compared with the power set value 51 to obtain a determination result. When the change of the transmit power exceeds the range of the power set value 51, the control circuit 60 can output a control signal to reduce the wireless. The energy of the communication signal. The power detection module 41 may include a Schottky diode D and other matching software, firmware or hardware, but the invention is not limited to this electronic component. The power detection module 41 is configured to detect the amount of change in power. Since the shape of the antenna module 20 changes when the user's head or hand approaches, the load of the mobile communication device 10 changes, and the transmission power of the power amplifier 30 also changes. Therefore, the power detection module 41 can detect the power of the power amplifier 30 to obtain a determination result to know whether there is a human head or a hand approaching. In the first embodiment of the present invention, the control circuit 60 includes a radio frequency transceiver 61 and an antenna control circuit 62, but the invention is not limited thereto. The radio frequency transceiver 61 is connected to the power amplifier 30 by means of a software with a hardware architecture or a hardware-to-hardware architecture for receiving or transmitting signals to be amplified by the power amplifier 30. Therefore, when the RF transceiver 61 receives the judgment result, the control signal is output according to the judgment result, and the signal energy of the low transmission to the power amplifier 30 is reduced by 201228431 to linearly reduce the output power of the power amplifier 30. As a result, the energy of the wireless communication signal transmitted via the power amplifier 30 can be reduced. The antenna control circuit 62 is formed by a hardware architecture for switching between different antennas. In this embodiment, the antenna module 20 has the first antenna 21 and the second antenna 22, but the invention is not limited thereto, and may have more than two sets of antennas, so that the power amplifier 30 can be different. The antenna is electrically connected. For example, when the power amplifier 30 is electrically connected to the first antenna 21 in general, the wireless communication signal is transmitted via the first antenna 21. After receiving the determination result, the antenna control circuit 62 outputs a control signal according to the determination result to switch to the second antenna 22 to transmit the wireless communication signal with lower energy. It should be noted that the present invention is not limited to having both the RF transceiver 61 and the antenna control circuit 62, and it is also possible to use only one of the circuit components to adjust the energy of the transmitted wireless communication signal. 4 and FIG. 5 are related to the second embodiment of the mobile communication device 10, wherein FIG. 4 is a schematic structural diagram of a second embodiment of the mobile communication device of the present invention, and FIG. 5 is a mobile communication of the present invention. A circuit diagram of a second embodiment of the device. In the second embodiment of the present invention, the detection circuit 40 is a current detection module 42 that stores a current set value 52. The current detected by the current detecting module 42 is compared with the current set value 52 to obtain a determination result. When the current changes exceed the current set value 52, the control circuit 60 can output a control signal to reduce the wireless communication signal. Energy. The current detecting module 42 is electrically connected to the power amplifier 30 for detecting whether the current flowing through the power amplifier 3G is changed by 201228431. The current detecting module 42 may include a precision resistor R and other matching software, firmware or hardware 'but the invention is not limited to this electronic component. The current detecting module 42 can detect the instantaneous current change or the relative voltage change of the precision resistor to know whether the current flowing through the power amplifier 30 changes. Since the load of 10 changes when the mobile communication is installed, the current flowing through the power amplifier 3G also changes. Therefore, it is possible to obtain a bribe result by the current detecting module 42 to produce a power wire of 30, and it is known that (4) the head of the human body is close to the material. In the second embodiment of the present invention, the radio frequency transceiver 61 or the antenna control Wei Lu 62 is also used to reduce the communication mode and the first real money type (4), so it is not described here. Next, please refer to FIG. 6 for a flow chart of the steps of the method of the difficult mobile communication device of the present invention. It should be noted that the method for adjusting the mobile communication device of the present invention is described below by taking the mobile communication device 10 as an example. However, the method for communicating the agricultural device is not limited to the use of the af device 10 in the foregoing.

In this way, the energy of the wireless communication signal can be reduced, but the invention is not limited to the use of the above method to reduce the energy of the wireless communication signal. The detection manners in steps 602 to 604 can be referred to as shown in FIG. 7. FIG. 7 is a flow chart of the first embodiment of the mobile communication device according to the present invention. Please also refer to the schematic diagrams of Figures 2 and 3. First, after step 601, step 701 is performed: detecting one of the power amplifiers to detect the load change. First, the power detection module 41 detects the transmission power of the power amplifier 30. For example, the Schottky diode D is used for detection, but the present invention is not limited to this electronic component. In this way, the power detection module 41 can know the transmit power of the power amplifier 30, and know whether the load has changed by the change of the transmit power. Next, proceed to step 702: determining whether the change in the transmit power exceeds the power set value to generate the determination result. Then, the power detection module 41 reads the power setting value 51 stored in the setting database 50 to determine whether the amount of change in the transmission power exceeds the power setting value 51 according to the detected transmission power to generate a determination result. Next, step 703 is performed: determining, according to the determination result, whether the output control 201228431 control circuit 60 determines whether to output the control signal according to the determination result, so as to reduce the energy of the wireless communication signal transmitted by the mobile communication device 10. If it is known from the judgment result that the amount of change in the transmission power is still within the range of the power set value 51, then returning to step 701, the transmission power of the power amplifier 30 is continuously detected. When the amount of change in the transmit power exceeds the range of the power set value 51, step 605 is performed to reduce the energy of the wireless communication signal. On the other hand, the detection methods in steps 602 to 604 can also be referred to as shown in FIG. 8. FIG. 8 is a flow chart showing the steps of the second embodiment of the mobile communication device of the present invention. Please also refer to the schematic diagrams of Figures 4 and 5. First step 801: detecting a current flowing through the power amplifier to know the load change. First, the current detecting module 4 2 flows through the current of the detecting power amplifier 30. For example, the current change or the voltage change of the precision resistor R is detected, but the present invention is not limited to this electronic component. In this way, the current detecting module 42 φ can know the current flowing through the power amplifier 30 and know whether the load has changed by the change of the current. Next, step 802 is performed to determine whether the change in the current exceeds the current set value to generate the determination result. Then, the current detecting module 42 reads the current setting value 52 stored in the setting database 50 to determine whether the current variation of the power amplifier 30 exceeds the current setting value 52 according to the detected current to generate a determination result. 201228431 Next, step 803 is performed to determine whether to output a control signal based on the result of the determination. The control circuit 60 determines whether or not to output the control signal ’ based on the result of the determination to reduce the energy of the wireless communication signal transmitted by the mobile communication device 10. If it is known from the judgment result that the amount of change of the current is still within the range of the current set value 5 2, then returning to step 801, the current flowing through the power amplifier 30 is continuously detected. When the amount of change in current exceeds the range of the current set value 52, step 605 is performed to reduce the energy of the wireless communication signal.
