Concrete, as it is shown in fig. 7, this control system includes four controllers, respectively display panel, interior machine controller, compressor controller and outer machine controller, corresponding address difference 1��4. The whole process that Fig. 7 inquires about data for the outside machine controller of display panel illustrates.
First, display panel have sent the Frame with query function code to outer machine controller, dotted line above section in Fig. 7, and the 1st data of this Frame are source address, and in the drawings, source address is 1, represent the address of display panel; 2nd data are destination address, and in the drawings, destination address is 4, represents the address of outer machine controller; 3rd data are function code, and in the drawings, function code is 1, represent inquiry; 4th data are data type, and corresponding to the row of controller data summary table, the 5th data are initial address, and corresponding to the initial row address of controller data summary table, the 6th is data number. In Fig. 7, the column address meaning that the display panel outside machine controller outer machine controller tables of data of inquiry of this frame is 19, and initial row address is the numerical value of two data of 0. In figure 12 it can be seen that the data read are compressor virtual condition and fan condition.
Then, outer machine controller sends response to query data to display panel, and in Fig. 7, dotted line is with lower part, and source address is the address of outer machine controller, and source address is 4; Destination address is the address of display panel, and destination address is 1; Function code is 2, represents inquiry response. The column address meaning that outer machine controller notice display panel tables of data of this frame is 19, and initial row address is the value of the numerical value (virtual condition and fan condition) of two data of 0 is all that 1,1 expression runs, and completes this process. Reach a controller by this process and obtained, to another controller, the data that the former needs, such that it is able to according to the data got, do further control.
Fig. 8 sends the whole process of control instruction for the outside machine controller of display panel, and source address is the address of display panel, and source address is 1; Destination address is the address of outer machine controller, and destination address is 4; Function code is 3, represents and controls. Before sending Frame, 17 row 0 row of outer machine controller tables of data, in figure 12 it can be seen that be switching on and shutting down, numerical value is 0, represents shutdown. Then the outside machine controller of display panel sends and controls data, changes the data of 17 row 0 row into 1, the switching on and shutting down of outer machine controller is also just set to start, and outer machine controller is according to this open state, performs boot action, such as blower fan and compressor is opened. Fig. 8 achieves a controller and sends the purpose of control instruction to another controller.
Fig. 9 is the controller data summary table of air conditioning unit control system, Figure 10-Figure 13 represents the tables of data of each controller respectively, can be seen that, the valid data of each controller are the subsets of data summary table, and different controllers exists common data, as interior machine controller and outer machine controller have switching on and shutting down, all of controller is protocols having version and device type all, same data, are independent in its value of different controllers, it is possible to take different values.
Preferably, tables of data except the 0th��16 row, the analysis mode of every string is just as, and the data such as the 17th row are all the revisable data of Boolean type, and 1 be effective, and 0 is invalid; The data of the 18th row be all the analog data that actual value is equal to transmission value, and are read-only, such as ambient temperature, as 26, then it represents that 26 degree; The data of the 19th row are all the data that Boolean type is read-only, and 1 is that effectively 0 is invalid.
The data type 0��15 of tables of data is used to indicate which data of tables of data are effective, and which function code is effective. Specifically, line number is 2��15 14 data of the 0th row of this data field, altogether 14*8=112 position, each corresponding a kind of data type, is that the corresponding data type of 1 expression is used in affiliated device node, and 0 expression is not used. The highest order corresponding data Class1 6��127 respectively to the byte that line number is 15 is started from the lowest order of the byte that line number is 2. It can be seen that the 16th��19 row have valid data in the controller data summary table of Fig. 9, the 20th��23 row do not have valid data, so the 0th arranges the 2nd behavior 00001111.
The line number of the 0th row of this data field is 32��255,224 bytes, in order each two byte correspondence one data type altogether, respectively corresponding data Class1 6��127. First character joint represents that the initial use section of the data of corresponding data category is (in row, preferably, every 8 data are a section, from row address 0,0��7 is first paragraph, 8��15 is second segment, by that analogy), and the hop count that second byte representation begins to use from above-mentioned the initial segment. In the controller data summary table of Fig. 9, the 16th row only the 0th��1 row effectively, also just only has the 1st section effectively, so initial use section is 1, using hop count is 1, namely the 0th arranges the 32nd behavior 1, the 33rd behavior 1.
2nd row of this data field arrange to the 15th, 14*256=32*112 byte altogether, and the service condition of the corresponding a kind of data category of every 32 bytes, corresponds respectively to the 16th��127 these 112 kinds of data categories in order. 32 bytes have 32*8=256 position altogether, start the service condition of highest order the 0th��255 data of corresponding corresponding data category respectively to the 32nd byte from the lowest order of the 1st byte, and 1 represents that corresponding data use, and 0 expression does not use. In the controller data summary table of Fig. 9, the 17th row only 0 row and 1 row have use, so the 2nd numerical value arranging the 32nd row is 00000011.
Additionally, the data of the 0th��15 row must be carried out assignment according to its tables of data by each controller. Other controllers by read this controller these data it is known which data this controller has be effective. In order to save data read time, first have to read 2��15 row of the 0th row, determine which row whether have use, then for the row having use, read the service condition of the section of respective column in the 32��255 of the 0th row again, again for the situation using section, read the data service condition of corresponding section in the 2nd��15 row. Preferably, if the time can accept, it is possible to directly read all data of the 2nd��15 row, it is possible to which data that have knowing tables of data are effective.
As can be seen from the above description, present invention achieves following technique effect:
In above-mentioned tables of data, each data type has abundant data space for defining data sense, it is possible to along with follow-up development re-defines undefined part. The set of the data of defined part is exactly data summary tables so that data summary table possesses autgmentability.
