Embodiment
Single-chip microcomputer mainly realizes the collection/process to relevant parameter and control decision output, and is sent to touch screen by serial ports, receives the parameter setting that touch screen is sent simultaneously, is stored in the middle of single-chip microcomputer flash, as shown in Figure 3.
Measure parameter and retain 1 decimal, transmit in hexadecimal form.Single-chip microcomputer is as follows with the communication protocol of touch screen:
Touch screen transmission packet (4 byte):
Single-chip microcomputer return packet (9 byte):
| Packet header | Temperature | Humidity | THI | State | Bag tail |
| @ | 2 bytes | 2 bytes | 2 bytes | 1 byte | ！ |
When single-chip microcomputer receive command code be 03 time, continue waiting for receiving the packet sent of touch screen, totally 10 bytes, after being stored in flash, send 03 response, touch screen receives response and represents that setting completes.
For avoiding the frequent movement of relay, fan control uses back stagnant mode, i.e. open fan during THI ＞ 68, closes fan during THI ＜ 66.The judgement of spray cycle and time was carried out during two weeks, and as THI ＞ 90, the working cycle is 5 minutes, then will no longer carry out the adjustment in spray cycle in these 5 minutes.
Touch screen is used for the parameters such as the humiture of displaying scene, simultaneously as the bridge of single-chip microcomputer Yu upper PC, it is achieved measurement result is uploaded to host computer, forwards and arranges the functions such as parameter.Touch screen mainly has 2 interfaces: parameter/state shows and sets interface.
As shown in Figure 4: touch-sensitive screen application uses Visual Studio instrument, VB.net technological development, enables 2 road RS485, is respectively used to communicate with single-chip microcomputer (COM2), wireless module (COM1).With the communication of single-chip microcomputer, touch screen, as main frame, sends reading order with the interval of cycle 1s to single-chip microcomputer, processs and displays after receiving return packet；With the communication of wireless module, touch screen, as from machine, after receiving the read instruction of upper PC, returns corresponding measurement/state value.Its workflow such as Fig. 4, mainly includes that data process/display, and single-chip microcomputer and the communication of host computer, and the setting of meter parameter, arranges including pasture title, cowshed number, group number and password, parameter is deposited in
Residentflash2 GUI address .Txt.
Touch screen is as follows with the communication protocol of host computer:
Host computer transmission packet (10 byte):
(1) reading order
(2) setting command (10 byte):
Setting command can send after sending the reading order that command code is 03, and touch screen is directly forwarded to single-chip microcomputer after receiving.
Touch screen transmission packet (12 byte):
When arranging state, touch screen receives the response (03) that single-chip microcomputer sends, and is directly forwarded to host computer.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and without departing from the spirit or essential characteristics of the present invention, it is possible to realize the present invention in other specific forms.Therefore, no matter from the point of view of which point, example all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in the present invention.Should not be considered as limiting involved claim by any reference in claim.
