Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
A kind of method changing peripheral equipment firmware provided by the invention, the method realizes flow process as it is shown in figure 1, details are as follows:
Step S11, terminal unit receive change peripheral equipment firmware instruction, are packaged into packet, and described instruction includes the data of needs change, and described packet includes the command id that can distinguish audio signal.
Further, when by terminal unit, user finds that external equipment has new upgrade data to issue, user chooses whether that needs are updated, when determine need update time, terminal unit receives the instruction of upgraded external equipment firmware, and required upgrade data is packaged into packet, during in order to make external equipment receive this packet, identify the packet that this packet is required upgrading exactly, but not general voice data, during encapsulation, described upgrade data is added command id, this upgrade data and other voice datas are effectively distinguished by adding command id, exclusive PCR, described command id can by adding the word string realization preset to upgrade data, for instance the lead code 020 default to the addition of upgrade data and rear leading code 040.
Wherein triggering the situation receiving change peripheral equipment firmware instruction and have a variety of, for instance when external equipment needs more news, now instruction includes the data of needs change and is specially upgrade data;Or external equipment starts a leak and needs to carry out situation about repairing, now instruction includes the data that needs change and is specially leak patch; Or need the authority of external equipment is modified, it is authority amendment data that now instruction includes the data of needs change.
Described packet is encoded being converted to pulse signal by step S12, terminal unit, is sent to external equipment by audio interface.
Step S13, external equipment receive described packet, trigger the operation of change peripheral equipment firmware by reading described command id.
Further, described external equipment reads the packet that audio interface sends in real time, if reading the packet of described transmission containing described command id, such as read current data packet when comprising default lead code 020 and rear leading code 040, then think that this packet is for change packet, triggers the operation of change peripheral equipment firmware; If external equipment does not read described command id, then it is not modified the operation of peripheral equipment firmware.
Wherein when receiving the packet that audio interface sends, in order to get rid of the interference signals such as voice data exactly, by the command id of the normal audio the distinguished information in read data packet, the packet sent is identified, effectively get rid of audio signal, accurately trigger the operation of change peripheral equipment firmware change.
The operation of step S14, external-device response change peripheral equipment firmware, is decoded converting binary stream to described packet, changes corresponding data.
As a preferred embodiment of the present invention, in order to accelerate firmware change efficiency, enable external equipment get more accurately simultaneously and effectively change data, the problem such as shortage of data that data are formed after coding transcoding can be repaired, reducing the data bit error rate in coding and decoding process, described method also comprises the steps:
Adding check information in described packet, described check information is the corresponding check information formed according to the described data needing change;
External equipment according to described check information, verification that described binary stream and check information are compared.
Specifically, in order to reduce the bit error rate further, enhance the accuracy of firmware change, described binary stream and check information are compared verification time, described binary stream can be sequentially carried out even-odd check, CRC check.
Fig. 2 illustrates the theory diagram of the change peripheral equipment firmware device that the embodiment of the present invention provides, and for the ease of illustrating, illustrate only embodiment of the present invention relevant portion. In the present embodiment, should include based on the device of audio interface change peripheral equipment firmware: pre-procesor 21, dispensing device 22, reception device 23, process device 24.
Wherein pre-procesor 21, are used for receiving change peripheral equipment firmware instruction, are packaged into packet, and described instruction includes the data of needs change, and described packet includes the command id that can distinguish audio signal; Dispensing device 22, for being encoded being converted to pulse signal to described packet, is sent to external equipment by audio interface; Receive device 23, receive described packet, trigger the operation of change peripheral equipment firmware by reading described command id; Process device 24, for responding the operation of change peripheral equipment firmware, be decoded converting binary stream to described packet, change corresponding data, it is achieved that by the technical scheme that peripheral equipment firmware is modified by audio interface.
As a preferred embodiment of the present invention, in order to accelerate firmware change speed, reduce external equipment and carry out the time of firmware change, effective data can be got more accurately, described device also includes: calibration equipment, for according to the described data needing change, forming corresponding check information, and according to described check information, described binary stream is verified.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within protection scope of the present invention.
