Description

Power accumulation method for data transmission of high frequency level

The present technology transmits and receives a small amount of simple data in the frequency band for transmitting the reflected wave of the ionosphere, and the required transmission power of the terminal controls power required for transmission through power supply by applying power storage technology. It is a technique of radio wave transmission in which data is reached to the central base station 1 by minimizing the loss of data.

The ionospheric echo is mainly used for long-distance communication using the F1 and F2 layers of the ionosphere, but in recent years, it has given up its space in submarine communication and satellite communication, and applied only to the international calls of radio amateurs such as HAM and radio waves such as ships and maritime emergency calls. It is a reality.

In addition, due to the use of the reflected wave of the ionosphere, it has a lot of radio interference. Fading, telling phenomenon, and magnetic storm act as representative obstacles, and technically, with the efforts of amateur radio companies to achieve smooth long distance communication while minimizing such phenomenon The level has improved considerably, but it is certainly alienated from its technological applications in the area of modern wireless communications, which is to send large amounts of information faster and to carry it in the hands, and that will continue to intensify.

The ionospheric reflection wave is the mainstream of technological advancement as a radio wave for dialogue communication through voice, rather than a radio wave for transmitting and receiving dataized information, but also achieved the area for exchanging simple information data promised by CW and Morse code.

The conventional technology is to tune by applying a tuner and to find a matching frequency band to take a call to each other when a match is made. It has also been used mainly for shortwave broadcasts such as the Voice of America (VOA) and North and South Korea broadcasts.

The ionospheric reflector is an international radio band that has been designated and managed by the ITU or the Korea Radio Bureau, but the number of amateur radio companies has recently increased due to the atmosphere of reconciliation between North and South.

However, since the ionospheric reflected wave is gradually losing its function in the area of information communication due to the narrowing of communication distortion and frequency band rather than the advantage of long distance communication, there is no conventional technology applying the technical contents to be pursued by the present invention. .

Accordingly, the present invention minimizes and compresses data between the terminal 12 and the central base station 1 to transmit and receive a small amount of simple data, and the terminal 12 receiving the call signal to the central base station 1 restores (demodulates) the received data. After the matching operation with the data inputted to the central processing unit 1 of the terminal 12, it is determined whether the call is valid, and if the call signal is justified, after modulating the data to be transmitted and transmitting it to the central base station 1, At this time, it is possible to transmit and receive a small amount of simple data in the ionospheric echo band by developing a temporary transmission power control technique through power storage, which allows the modulated transmission data to be maintained until it reaches the central base station (1). This study aims to improve the utilization of ionospheric echo bands in living devices that want to exchange small amounts of simple data.

The signal for calling the terminal 12 is received by the central base station 1 and the received call signal calls out the data input into the database 11 and the called data is the unique device number and appointment in the central processing unit 1. The data is generated by including the identification number, preliminary number, receiver identification number, error correction code, etc. of the call, and the generated data is subjected to an encoding process modulated by the modem (3) and then mixed with the encoded data. The signal is transmitted to the encoder module 4, and the signal passing through the encoder module 4 is transmitted to the transmitter through the amplifier stage 6, and transmits data to the terminal 12 through the antenna. At this time, since the central base station 1 has sufficient transmission power, the power storage circuit is not applied.

The radio wave transmitted from the central base station 1 receives the radio wave from the terminal receiver 12, first amplifies the weakened radio signal through the amplifier 21, and then removes the noise from the filter circuit unit 20, and the decoder module ( 18, the carrier frequency and the data are separated, and the separated signal is demodulated back into the digital data in the modem 15 and transferred to the central processing unit 14, in the central processing unit 14 in the modem 15 The transmitted data is analyzed to determine whether to read data from the data to be transmitted or to transmit the last stored data according to the content of the data, and the central processing unit 14 modulates a digital signal for transmission of the determined transmission content. The modem 15 transmits the data back to the modem 15. The modem modulates the analog signal back to the encoder module 17, and the encoder module 17 transmits data to be transmitted to the carrier frequency. After transmitting to the amplifier stage 19 for transmission, the power required for transmission stored in the power control circuit 16 is transmitted to the transmitter 22 as much as the output required for transmission, so that the data reaches the central base station 1. Use the least amount of power you can.

After receiving the data from the terminal 12, the central base station 1 passes through the amplifier stage 9 to amplify the weak signal into the LEVEL of a constant size, and then filters the noise mixed in the amplified radio waves. After removing it, the carrier wave is transmitted to the decoder module 5 to separate the data, and the data separated from the decoder module 5 is demodulated again through the decoding process of the modem 3, and the demodulated data is centered to SERIAL. The central processing unit 2 stores the data received from the modem in a temporary buffer, checks whether the received data is valid, and if it is not the correct data, receives the received data. Delete from the temporary buffer and send again several times. If the correct data is a wireless data communication system that completes the transmission and reception of data once by transmitting a promise signal of receiving OK to the terminal 12, wherein the database 11 of the central base station 1, the device number, terminal number, It is a continuous wireless communication transmission method of storing the received data, the reception time, etc., and at the same time, converting the received data to make it easier to recognize and transmitting the signal to the calling signal. References are made to block diagrams in FIGS. 2 and 3.

However, since the frequency band to use the data transmission and reception technique is a region using the reflected wave of the ionosphere, a transmission power corresponding to several hundred times that of the microwaves used in the conventional techniques is required, and in the power storage circuit, the transmission required by the terminal 12 is required. It is used as a power source for wireless transmission by accumulating power in the SUPER CAPACITOR (C1) in the BOOST-UP method in order to obtain the desired power by connecting to a power source or a battery (herein referred to as a power source) to obtain the output power. In Fig. 1C was configured as a circuit. At this time, compare the voltage of power supply (BV_1) and SUPER CAPACITOR (CV_1) with comparator (U1A) to connect the power directly for faster charging. In the device 14, turn on the TR-Q3 or the relay lamp 25, and the power supply is directly connected to the SUPER CAPACITOR and charged first.Then, the voltage (BV_1) of the power supply and the voltage (CV_1) of the SUPER CAPACITOR are again compared to the comparator (U1A). ) Compare the charging voltage through) and if the power voltage (BV_1) is equal to the voltage of SUPER CAPACITOR (CV_1), turn off TR-Q3 or the relay lamp (25), and then central processing to obtain higher voltage than the power supply voltage. The device 14 generates a high-low repetitive B_CLK waveform to operate the TR-Q1 or FET 26 to allow secondary charge to proceed to the SUPER CAPACITOR C1. 1A, 1C, and 4 constitute circuits.

During secondary charging, the voltage (CV_1) of SUPER CAPACITOR (CV_1) and the voltage (HV_1) before BOOST-UP are compared through the comparator (UIB). When the voltage reaches a certain voltage, the state is transmitted to the central processing unit (14). The central processing unit 14 stops driving of the TR-Q1 or the FET 26 so that the signal of B_CLK is no longer generated, and the secondary charging is stopped. The circuit of FIG. 1B, 1C, and 4 is configured as a circuit. .

Referring to the signal characterized by the central processing unit 14 to operate the above-described circuit configuration, the signal input to the central processing unit 14 is a SUPER so as not to overcharge when secondary charging Comparing the voltage of the CAPACITOR (C1) and the BOOST-UP front end, the signal (CV_H) and the voltage of the voltage (CV_1) of the super capacitor and the power (BV_1) of the power supply are compared, and the state of the central processing unit (14) is compared. It consists of the signal (CV-L) input to the output of BV-ON according to the value of CV_L (BV_ON) signal is compared to the value of the voltage (CV_1) of the super capacitor and the voltage of the power supply (BV_1) TR Repeat the command to instruct Q3 or relay 25 to be turned on and off. In addition, the B_CLK signal is a circuit having a signal characteristic of turning on and off the TR-Q1 or the FET 26 so as to store energy stored in the inductor L1 in the SUPER CAPACITOR C1. When the same circuit configuration is made, it is possible to simply configure the central processing unit 14 to control the transmission and reception of data so that the continuous operation can be performed, and for the continuous operation thereof, FIGS. 1, 1A, and FIG. It is natural that the transmission output in the ionospheric reflection wave band which the present invention seeks is obtained by applying 1b and 1c.

As described above, the present invention provides a technique for temporarily outputting transmission power in an ionospheric reflected wave frequency band so that expensive microwaves are required for a user who needs only the transmission and reception of simple data, such as finding a child, finding an elderly person, and locating location. It can replace the use of the terminal, and can avoid the technology fee to be paid to foreign countries in the microwave band, and it is possible to implement a low-cost terminal through a simple circuit configuration, which was previously considered impossible in the short-wave band It has the effect designed to be applicable to the application of HANDHELD TYPE.

In addition, in order to achieve the continuous development of the present invention, the development of the parts industry, such as SUPER CAPACITOR and the battery cell should be made, it will have the effect that can lead to technical induction of the parts industry.

As mentioned above, due to the characteristics of the short-wave frequency band using the reflected wave of the ionosphere, it has radio wave due to the telogen, fading phenomenon and magnetic storm. In the process of completing the present invention, it is possible to secure a technology that can significantly alleviate such interference. The effect of development can be achieved. This includes the effect of the opportunity to recognize the short-wave band as a frequency band that can be looked back on in the technical stage of wireless communication controlled by microwaves and to induce competitive development of technology development.
