[embodiment]
Fig. 1 shows the method flow of the control of an embodiment mesophytization analyser, comprises the steps:
Step S110, encodes and obtains valid data the steering order data of Biochemical Analyzer.
In the present embodiment, the steering order data of Biochemical Analyzer have comprised Electric Machine Control instruction, data acquisition instruction, thermostatic control instruction, liquid road steering order, light source control instruction etc., carry out corresponding action by steering order data Biochemical Analyzer.According to the coded system of setting, the steering order of Biochemical Analyzer is encoded to obtain valid data, these valid data are for the instruction transmission of Biochemical Analyzer.
In one embodiment, as shown in Figure 2, the detailed process of above-mentioned steps S110 is:
Step S111, carries out sequential encoding to steering order data, is the character string of default byte length by each steering order data transformation.
In the present embodiment, in steering order data, carry out sequential encoding according to certain coded system, each steering order data is converted, make each obtained character string meet the byte length of setting, and corresponding steering order data.In a preferred embodiment, steering order data are decimal system numerical value, default byte length is 3 bytes, according to ASCII (American Standard Code for Information Interchange, ASCII(American Standard Code for information interchange)) numeral in code table converts each steering order data, for example,, if a certain steering order data are " 1 ", according to the character string " 001 " of 3 bytes of the numeral in ASCII character table " 1 " conversion; If a certain steering order data are " 156 ", the character string that conversion obtains is " 156 ", and now, the character string that conversion obtains is numeral.
Step S113, the character of changing one by one in the character string that this conversion obtains according to the scale of setting obtains valid data.
In the present embodiment, convert the character string obtaining for the coded system by certain, according to the scale of setting, character string is changed one by one, this scale can be septenary, scale-of-eight, the duodecimal number system and sexadecimal etc., in a preferred embodiment, system position is sexadecimal, according to sexadecimal, the character conversion in character string is become to sexadecimal numerical value.For example, if character string is " 001 ", corresponding three character conversion are " 0x30,0x30,0x31 "; If character string be " 156 " corresponding three character conversion be " 0x31,0x35,0x36 ", the character string obtaining due to conversion is numeral, and the numerical value being converted to according to sexadecimal is all with 0x3 beginning, becomes 0x30,0x31,0x32, the form of 0x33....
Because data in actual transmitting procedure are transmitted with binary form, and conversion between sexadecimal and scale-of-two is comparatively easy, and the conversion that adopts sexadecimal to carry out character string can improve transfer efficiency.
Step S130, adds frame head character and postamble character to valid data and forms communications data frame, and send, this frame head character and postamble character all with valid data in the not repetition mutually of arbitrary character.
In the present embodiment, in transmitting procedure, be to carry out with the form of Frame, therefore, in valid data, add frame head character and postamble character, the frame head character adding and postamble character have adopted identical scale with valid data, and be alphabetical corresponding scale numerical value in ASCII coding, to avoid following valid data to obscure.For example, if valid data are sexadecimal numerical value, frame head character and postamble character are sexadecimal numerical value corresponding to certain letter in ASCII character table, wherein, frame head character can be 0xfa, postamble character can be 0xfb, distinguishes with the valid data of 0x3 beginning, has avoided the generation of segmentation errors in communications data frame.
Step S150, received communication Frame, and communications data frame is carried out to the controlled director data of decoding.
In the present embodiment, the communications data frame receiving is carried out to decoding and reduce controlled director data, according to the cataloged procedure of steering order data, first communications data frame is cut apart and removed frame head character and postamble character, and the communications data frame after cutting apart is converted to character string, and then convert character string to steering order data corresponding scale numerical value.For example, if the communications data frame receiving is sexadecimal numerical value, steering order data are decimal system numerical value, in ASCII character table, arbitrary sexadecimal numerical value is corresponding with character, the process of communications data frame being carried out to decoding is: the sexadecimal numerical value in communications data frame, according to the form of ASCII character table changed string, and then is transformed to steering order data by character string, and decode procedure is the inverse process of cataloged procedure.
Forming after communications data frame, sending it to the command reception thread of Biochemical Analyzer.Command reception thread enters the controlled director data of decoding to communications data frame after receiving communications data frame, and communicates with the instruction execution thread of mail box fashion and Biochemical Analyzer, and the steering order that decoding is obtained sends instruction execution thread to.
Step S170 carries out the steering order data that decoding obtains in Biochemical Analyzer.
In the present embodiment, in Biochemical Analyzer, each steering order data is all corresponding one perform an action, the instruction execution thread of Biochemical Analyzer moves according to steering order after receiving steering order data.Particularly, these steering order data comprise speed parameter, and the above-mentioned step of carrying out the steering order data that decoding obtains in Biochemical Analyzer comprises: according to the motor of speed parameter control Biochemical Analyzer.This speed parameter obtains in actual debug process, for controlling acceleration and the moderating process of motor, make to rotate starting in electric machine rotation process and accelerate and stop linear the rising and linear decline of process implementation of slowing down, and then reduce and process expending in a large number of resource.
