The control unit 11 is connected to the infrared learning receiving unit, the memory unit 13, the infrared code transmitting control unit 1411, the wireless transmitting and receiving unit 15, and the adjustable frequency oscillation generating unit 16, respectively.

Referring to FIG. 2, the infrared code learning receiving unit 12 receives a first infrared code signal from the outside, and the infrared code learning receiving unit 12 further analyzes an infrared command code information IR1 and an infrared carrier signal IR2 from the infrared code signal. The control unit 11 simplifies into a digital control signal information according to the first infrared command code information IR1 and through a simplified operation, and stores the digital control signal information in the memory unit 13.

The wireless transceiver unit 15 is communicatively coupled to an external back end platform 2. The wireless transceiver unit 15 further transmits the second digital control signal information stored in the back end platform 2 to the control unit 11, and the second digital control signal information and the digital control signal format information have substantially the same field format. The control unit 11 instructs the adjustable frequency oscillation generating unit 16 to provide a carrier signal to set the second infrared signal according to the carrier frequency information of the second digital control signal information. Then, the control unit 11 further sets the infrared code transmission control unit 1411 to emit a second infrared code signal according to the second digital control signal information.

In order to provide the relay service, the control unit 11 further receives a relay instruction from the back end platform 2, and the control unit 11 sets the wireless transceiver unit 15 to receive one of the external wireless packets according to the indication of the relay indication, and determines that the wireless packet includes The destination address information is followed by the wireless transceiver module monitoring the wireless packet after the destination address information conforms to the control list of the control group, and if not, forwarding the wireless packet.

The foregoing digital control signal information further includes a page number (Pages) field information, a sequence field information, a carrier frequency field information, and a carrier frequency field information. The page number field information is the number of memory pages required to record the digital control signal information, and is used as reference data when the digital control signal data is converted into an infrared code or cut into a wireless packet. The sequence field information records the access index sequence value of the digital control signal information in the memory unit 13, so that the user only needs to know the sequence field information at the far end to control the plurality of home appliances 3 on the back end platform 2. . The carrier frequency field information records the transmitting carrier frequency of the digital control signal information, and causes the control unit 11 to operate the adjustable frequency oscillation generating unit 16 to generate a carrier signal of the desired carrier frequency, and then to transmit the carrier signal. The infrared command code is combined with the carrier signal for transmission. The control code length field information is the number of bytes in which the digital control signal information is recorded.

The simplified operation system samples a pre-processed signal information for the first infrared command code information IR1, and the pre-processed signal information includes a plurality of control code groups sequentially associated with each other, and performs a noise filtering operation on the pre-processed signal information. And performing a data judgment on the data of each control code group through the pre-processing signal information of the noise filtering operation to successively perform a streamlined operation, wherein the data is judged to be greater than the predetermined data in each control code group. The cropping is performed, and the streamlined job is the byte space required for each control code group.

Further, in order to avoid unnecessary interference of the free space noise to the wireless infrared control converter 1, the control unit 11 then performs noise filtering on the preprocessed signal information, and the noise filtering operation system is less than Pre-processing signal information of 15 control code groups and the first group of control code groups and the second group of control code group start bits are too short (the sum of the sample data of the first group and the second group is less than 500, the judgment is too short) ), the pre-processed signal information is treated as noise and filtered. When the control code group is lower than 15 groups, the control unit 11 records this time as the failure mode data, and the data will automatically end without any further processing.

The streamlined operation system stores the first and second direct plan 2 bit space spaces of the control code group, and the data of the third to last group is divided by the conversion operation of 4, and the result of the change operation is performed. The memory unit 13 plans to store 3 byte spaces to store quotients greater than 255, or to plan 1 byte space to store quotients less than 255. When the remaining number of conversion jobs is 3, the quotient is carried, and if the remainder is 1 or 2, the remainder is rounded off and the quotient is carried. If the data of any control code group without a simplified operation is greater than the predetermined number "25000", it is regarded as a repeated signal of continuous transmission of infrared rays, and will need to be cut, for example, directly cutting all subsequent data.

Since the infrared code length of each home appliance remote controller is different, the last digital control signal data generated by the home appliance varies from 1 to 3 Pages, that is, the shortest is 1 Page (264 bytes), and the longest is 3 Pages. (792 bytes).

The wireless infrared control converter 1 described above temporally samples the positive and negative edge signals of the first infrared command code information IR1, and the reference frequency of the sampling is 360 kHz, and the purpose of the sampling is to calculate each of the first infrared command code information IR1. The length of time of the signal bit period. Please refer to Figure 3, the data calculated by the infrared command code information IR1 is the pre-processed signal information.

The pre-processed signal information records the start bit of the infrared command code information IR1 to the last end bit. The first control code group represents the period length data calculated under the reference frequency of 360 KHz for the start signal, and each group occupies about 2 bytes.

After the above simplified operation, the pre-processed signal information is converted into digital control signal information, that is, the first control code group and the second control code group data are unchanged, and the data contained in the third control code group is carried out. Simplified to save storage space.

Please refer to FIG. 3, which is a bitmap of the digital control signal information field of the present invention. Digital control signal information and infrared code parameters, such as: page number field information, sequence field information, carrier frequency field information, control code length field and digital signal code, and The 264-byte size of each page is cut and becomes a single-digit digital control signal data and stored in the memory unit 13.

In the front field of the second digital control signal code information, 0x00 is added to enhance the management performance of the memory, so that the user does not get the wrong query information when using the order field information to query.

When the memory unit 13 stores 2048 pages (Pages), the number of pages per page is 264 bytes, and the space occupied by each digital control signal data is from 1 page to 3 pages. Not waiting. In the case of the simplified operation of the present invention, the past digital control signal data requires a maximum of 7 pages of capacity, that is, 1848 bytes of space is required, and the simple job processing of the present invention requires up to 3 pages. The capacity of the number.

When the digital control signal data is transmitted between the wireless transceiver unit 15 and the back end platform 2 (the first or the second digital control signal data), the control unit 11 removes the 0x00 data in the plurality of digital control signal data. It is then integrated into an array of data, and the array data is cut into 11 bytes of data for transmission.

Please refer to FIG. 4, which is a first application scenario of the present invention. When the remote platform wants the wireless infrared control converter 1 to send an infrared code signal to operate the first home appliance 3, the remote platform first transmits and transmits. The command is given to the control unit 11, and the control unit 11 sets the adjustable frequency oscillation generating unit 16 to generate the required carrier signal according to the transmission command. Next, the control unit 11 superimposes the signals to be transmitted, and instructs the infrared code transmission control unit 1411 to transmit.

Please refer to FIG. 5, which is a second application scenario of the present invention. The user sets the wireless infrared control converter 1 to perform a wireless relay operation through the backend platform 2. When the wireless transceiver unit 15 receives the wireless packet, the destination address information is first parsed. If the destination address information is located in the control converter list, the control unit 11 will instruct the wireless transceiver unit 15 to monitor the wireless packet. If the destination address information of the wireless packet is not included in the control converter list, the wireless packet is automatically forwarded and transmitted to other wireless infrared control converters 1 to achieve the effect of the wireless relay.
