In the present invention, the "robust wireless transmission method" refers to a frequency band (eg, an unlicensed industrial scientific and medical band, an unlicensed low power frequency band, etc.) and a local characteristic that are not limited to the use of frequency in short-range wireless communication. According to the regulation / regulation of the Radio Law, the weak radio wave of UHF (ultra high frequency) band is selected and the same frequency band (one common channel, e.g. 125MHz of 5.725 ~ 5.850GHz) can be operated by multiple users simultaneously. Even when shared, the error rate of data transmission in the range of -3 to 10 to -10 power of 10 (BER: Bit) from the influence of intentional or unintentional multiple access interference between different users or adjacent different frequency bands. It is possible to independently protect the channel assigned between the original signal and the user with the quality of communication transmission with error rate, and the modulated signal form is TDMA RF unit.

And OOK modulation technology are included, and a built-in MCU (Microprocessor) and flash memory for program storage.

In the present invention, the guardian uses the robust wireless transmission method using a weak radio wave of the UHF band, the infant-only outgoing baby / important article monitoring device 900 infants (for example, under 5 years old) (or bags, key chains, wallets) Etc.) [the method of carrying wears it with a lock, puts it in an invisible pocket, clips it, etc.], as shown in the flowchart of FIG. 20, the portable multifunction device 600 Pressing the MIA prevention key (eg, mutual combination of existing keys, * key 2 + # key 2), the portable multifunction device 600, every predetermined time period (eg 3 seconds) the outgoing dedicated infant / important The object monitoring device 900 checks whether a transmission signal (eg, WITH) is coming, and if the transmission signal (WITH) does not come more than a predetermined number of times (eg, two times), a warning message is immediately displayed to the guardian (melody, voice, indication). , Vibration, etc.).

Accordingly, the portable multifunction device 600 demodulates a transmission signal transmitted from the transmission-only infant / important article monitoring apparatus 900 through the robust radio unit 602 using its robust radio transmission method. You can check it.

Hereinafter, the operation of the robust radio transceiver according to an embodiment of the present invention will be described.

First, as shown in the flow chart of Figure 2, the operation of the robust radio method will be described. Any baseband modulation and demodulation method known so far that the maximum output is up to 100mW (20dBm) in the first frequency (ISM / UHF weak radio wave / unlicensed low power frequency) band and TDMA RF (Radio Frequency) components can be used. Look for them (S1).

The minimum BER for each data to be transmitted is defined as an example as follows to find a method of obtaining the best BER performance suitable for transmitting simple data and multimedia among the selected known or private baseband modulation and demodulation methods (S2).

Minimum BER for H.264 video <10 ^-5

Minimum BER for ADPCM Audio <10 ^-3 to 10 ^-4

Minimum BER for simple data <10 ^-8 to 10 ^-10

 The channel is configured by using a known (or private) baseband modulation and demodulation method, and then the minimum BER for each generated channel is measured to classify the channel by transmission data type to examine the performance of the channel. The method is, for example, a transmission / reception system configured to measure a BER with the number of error bits of the specific pattern found when synchronizing a specific pattern (eg, 128-bit G and GB) when transmitting and receiving. It is determined that the quality of the channel is good (S3).

Therefore, it is determined whether the selected baseband modulation and demodulation method is a baseband modulation and demodulation method that can form a transmission channel having the performance of the minimum BER range defined for each data to be transmitted (S4), or by selecting a different baseband modulation and demodulation method. Repeat the process (S5). Then, by using the best method of the determined baseband modulation and demodulation method, it transmits by channel (S6, S10, S12) defined according to the characteristics of the data to be transmitted.

That is, when data to be transmitted is input, the data determination unit 111 determines whether the input data is simple data or multimedia data. If the input data is simple data and is transmitted using the UHF band (S7), the modulation / demodulation unit 112 modulates the data including the OOK (On / Off Keying) modulation scheme as shown in FIG. 3 (S8). ), The TDMA RF transceiver 120 wirelessly transmits this data through the UHF transceiver 122. If the input data is simple data (S9) or video (S11) or audio data (S13) that do not use the UHF band, the modulation / demodulation unit 112 compresses the data in the case of multimedia data as shown in FIG. After compressing according to the format to reduce the capacity of the data, and performs a data modulation process that does not include the OOK (On / Off Keying) modulation method, the transceiver 120 is to transmit this data through the ISM transmitter and receiver 121 Wireless transmission.

On the other hand, in the case of receiving data, data is received through the ISM transmitter / receiver 121 in the case of simple data and multimedia data that do not use the weak radio waves of the UHF band according to the type of data received, and the weak UHF band. In the case of simple data using radio waves, since data is received through the UHF transceiver 122, a separate data determination process is not required. The data thus received is processed in the reverse order to the above transmission process. That is, in the case of simple data using weak radio waves in the UHF band, the data received through the UHF band transceiver 122 from the transceiver 120 is converted by the OOK (On / Off Keying) demodulation process in the modulator 112. The data is demodulated and converted to the original simple data. In the case of simple data and multimedia data that do not use the weak radio wave of the UHF band, the transceiver 120 is received through the ISM transceiver 121 so that a separate data determination process is not required. The received data is demodulated by a demodulation process that does not include an OOK (On / Off Keying) modulation scheme in the demodulation unit 112 and is reduced to original simple data and multimedia data through a process of decompression.
