Embodiment
With reference to the accompanying drawings, idealized embodiment of the present invention is described in detail.
Fig. 1 is the synoptic diagram that the present invention utilizes the product upgrading system of wireless channel to constitute.
As shown in Figure 1, product upgrading system of the present invention uses TDC (transparent data channel, the Transparent Data Channel) function of RDS (Radio Data System), upgrading (upda te) program of operation product.
That is, by antenna 18, receive the product up-gradation data that send from the radio station, the product up-gradation data of utilizing 12 pairs of RDS decoder modules to receive are then decoded.
Here, the radio station that sends the product up-gradation data is provided with the wireless channel that sends above-mentioned upgrade data separately, perhaps utilizes existing radio station channel, sends above-mentioned upgrade data in the regular hour section, and the product up-gradation signal promptly is provided.
Then, the data of decoding by RDS decoder module 12 are transferred into microprocessor 13, microprocessor 13 according to the address to the above-mentioned data that send classify (sorting).
Then, the data storing that microprocessor 13 is classified according to the address is in external RAM 17.
Finish the reception of necessary data, and with data storing after external RAM 17 zones, and be installed in ROMPaq among the ROM14 of microprocessor 13 when starting production in advance.
At this moment, utilize the upgrade data that is stored among the said external RAM 17, in the flash memory (Flash Memory) 19 of microprocessor 13, carry out program upgrade.
In addition, about the time or the time period of upgrading beginning, aforesaid operations is as long as connecting power supply to upgrade-system just carries out, and is whether irrelevant with user's opening power.When the user uses product, do not carry out the reception and the upgrading of upgrade data, only in standby mode, just carry out the reception and the upgrading of upgrade data, so the present invention can be under the situation that does not delay user's use, automatically perform program upgrade, so just can avoid bringing inconvenience to the user.
In addition, upgrade-system has been owing to adopted wireless channel, so it comprises the tuner 11 that can adjust wireless channel and the control by microprocessor 13, the display 16 of the necessary step of display routine upgrading running.
Fig. 2 is the formation synoptic diagram of the group 5A as the RDS data layout of the present invention, and Fig. 3 is the formation synoptic diagram of group of the present invention 5B.
As shown in Figures 2 and 3, the ROMPaq of product is carried out the reception of data by the TDC function of RDS.
TDC is made of 32 channels altogether, TDC information can be by piece (Block) 3 and the piece 4 of group 5A, also have the piece 4 of group 5B to receive (annotate: the piece among Fig. 2,3 refers to the white portion between check word+offset amount (Checkword+Offset) A, B, C, the D, from left to right is followed successively by piece 1, piece 2, piece 3, piece 4).
Equally, from Fig. 2 and Fig. 3, can learn the detailed formation that the group is inner.The data volume that can receive by group 5A is 4 bytes (piece 3 is 2 bytes, and piece 4 is 2 bytes), and channel information is the address reception by the piece 2 of group 5A, can have 32 kinds altogether.
Therefore, can receive the data of 128 bytes (32 * 4 byte), the data area that can use 2 bytes (2 bytes in the piece 4) altogether among the group 5B.
This zone is used as the address area of appending of data, can be divided into 65536 kinds with 32 kinds again.That is, can transmit 8388608 bytes (128 bytes * 65536) data.
8388608 bytes are equivalent to 8 megabyte, can transmit the software of present any audio product.
The present audio product of making can be divided into the data of 128 byte unit 65536 addresses and carry out Data Receiving.
Fig. 4 is the product up-gradation process synoptic diagram that utilizes the product upgrading system of wireless channel among the present invention.
As shown in Figure 4, utilize the TDC function of RDS, receive the data (S11) of group 5A, distribute the address, store 4 byte datas (S12).
Then, receive the data (S13) of group 5B, if address and group 5A identical (S14) are just distributed and appended address (S15).
If receive 128 bytes (32 * 4 byte) (S16), will have identical data of appending 128 bytes of address and be sent to external RAM (S17) successively.
Then, confirm that the data that transmit are to receive data at last, thereby judge whether to finish the reception (S18) of necessary data.
If finished the reception of necessary data, eliminate original driver (S19) in the microprocessor flash memory, confirm whether be in the state that empties fully (Blink) (S20), then the data that store in the external RAM are sent to (S21) in the flash memory, in flash memory, carry out program upgrade (S22).
Then, carry out error-detecting, detecting has error-free information (S23) in the upgrade data that sends, if there is not error message (S24), with regard to the termination routine escalation process, so just provide many convenience to the user.
