Embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing below, technical scheme of the present invention is carried out clear, intactly description.
The schematic flow sheet of the data communications method that Fig. 1 provides for the embodiment of the invention one.As shown in Figure 1, this data communications method may further comprise the steps:
In practical application, the terminal provides operation interface to the user, listed in this operation interface that the user can select, to whole list of instructions that the terminal external equipment sends, the user can select arbitrary instruction wherein.The terminal is selected according to the user, generates the corresponding instruction data, and wherein, said director data is different from the voice data of prior art sound intermediate frequency interface transmission.
Particularly, terminal (like computer) COBBAIF through self directly is connected with the communication interface of terminal external equipment with data wire.Usually; COBBAIF only is applicable to transmission of analogue signal, and accordingly, step 102 is specially: the terminal is modulated to first analog signal with said director data; Said first analog signal comprises director data, and said first analog signal is sent to the terminal external equipment through COBBAIF.
In practical application, the terminal can utilize the modulation module that carries to convert the director data of digital signal form into carried director data first analog signal, and first analog signal is sent to the terminal external equipment through COBBAIF.
Correspondingly, the communication interface of terminal external equipment receives first analog signal from COBBAIF, comprises director data in this first analog signal; The terminal external equipment carries out demodulation process to first analog signal that is received, and particularly, the terminal is become digital signal through first analog signal conversion that COBBAIF sends over, and obtains director data; The terminal external equipment is carried out the corresponding instruction operation according to director data, particularly, according to and the terminal between the pairing command content of this director data of making an appointment, carry out corresponding operating, and generate response data.Wherein, response data can be the execution result of instruction data.For instance; The terminal external equipment comprises the memory module of the accounts information that stores fiscard; And the instruction " 00B082000A " of making an appointment between terminal external equipment and the terminal one and being used for reading of data; Wherein B0 represents reading command, the command file that 82 expressions are read, the length that 0A indicates to read.Then when the terminal external equipment received this instruction of sending at the terminal, the data that read 10 bytes were as response data.
The terminal external equipment carries out modulation treatment with the response data that generates, and particularly, modulation is meant that the response data with digital signal form converts second analog signal of having carried response data into, and with this second analog signal through being sent to the COBBAIF at terminal.
Particularly, second analog signal that send through COBBAIF receiving terminal external equipment at the terminal, said second analog signal comprises said response data, and said second analog signal is carried out demodulation process, and obtains said response data.Second analog signal that end-on is received is carried out demodulation, is meant second analog signal conversion is become digital signal, obtains the response data that second analog signal is carried.
Handled is carried out according to the response data that demodulates in the terminal, and for example, determining whether needs next the bar director data that sends or notify user's operating result etc.
It is pointed out that if the response data that obtains in the step 103 is encrypted, then also need before the step 104 earlier said response data to be deciphered.
Further, COBBAIF generally includes two kinds of data input and output (I/O) mouth, and a kind of is the audio frequency horn mouth that is used for externally sending data, and a kind of is the audio microphone mouth that is used for receiving from the outside data.Correspondingly, step 102 is specially:
Said director data is sent to the terminal external equipment through the audio frequency horn mouth.
Receive the response data that said terminal external equipment sends through the audio microphone mouth.
Further, present embodiment also comprises:
Said terminal supplies power for said terminal external equipment through COBBAIF.
Usually, the audio frequency horn mouth comprises left and right two sound channels, and present embodiment can be used for one of them sound channel between terminal and terminal external equipment, to transmit data, and another sound channel can be used for to the terminal external equipment electric energy being provided by the terminal.
The embodiment of the invention adopts the terminal to send director data through COBBAIF and gives the terminal external equipment; The terminal external equipment is handled and is generated response data and returns to the terminal to director data; The terminal receives response data through COBBAIF and carries out the technological means of handled; Can solve existing terminal COBBAIF can only with external audio frequency apparatus, carry out communicating by letter of voice data, the problem that the application of COBBAIF is restricted like external speaker equipment and microphone etc.Owing to all have COBBAIF usually on the terminal, so have excellent universality.Further, can also realize the coded communication between terminal and the terminal external equipment, improve the fail safe of communication.Especially when utilizing the data of communicating by letter between terminal external equipment and the terminal for need fail safe higher data; For example the terminal external equipment is the accounts information memory device that stores the accounts information of fiscard; When financial transaction was carried out through the accounts information that from account information storing device, reads fiscard in the terminal, it is particularly important that this coded communication just becomes.
The structural representation at the terminal that Fig. 2 provides for the embodiment of the invention two.As shown in Figure 2, this terminal comprises:
Wherein, COBBAIF comprises audio frequency horn mouth and audio microphone mouth, and communication module 22 specifically comprises:
Modulating unit 221 is used for said director data is modulated to first analog signal, and said first analog signal comprises director data;
For instance, if the response data that demodulating unit 224 demodulates is that processing module 23 specifically can be deciphered said response data before said response data is handled through the data after the encryption.
Above-mentioned terminal also comprises:
Supply module is used to utilize the bell-mouthed sound channel of said audio frequency, and external equipment provides electric energy to said terminal;
Further, first communication unit 222 specifically is used for said first analog signal is sent to the terminal external equipment through bell-mouthed another sound channel of said audio frequency.
The method of method embodiment shown in Figure 1 can be specifically carried out at the said terminal of present embodiment, and it realizes that principle and technique effect repeat no more.
