As shown in Figure 2, the UART single-chip microcomputer of slave computer is by 232-485 chip (can adopt model is the chip of MAX3082, MAX3081, MAX487), light isolating chip (can adopt model is the chip of PC817) and communication connector (can adopt two pin plugs) are connected communication cable, and the other end of communication cable inserts the standard RS232 interface of host computer by 485-232 converter (can adopt model is the converter of HF485N, HT4481).Communication cable can adopt two classes or three class twisted-pair feeders.
Master-slave mode is adopted in communication between host computer and the slave computer, and wherein, host computer is a main frame, and slave computer is a handset.Host computer control bus, and handset all has unique address, and main frame and handset be Data transmission mutually.In the present embodiment, the handset plane No. is consistent with the handset address.Bag data (the send sign indicating number) form that main frame mails to handset is: data+check code+end code such as the temperature of guidance code+handset plane No. (handset address)+set to this handset, pattern, air quantity; Bag data (the send sign indicating number) form that handset mails to main frame is: data+check code+end code such as the present temperature of guidance code+handset plane No. (handset address)+this handset, pattern, air quantity.
In host computer, systems soft ware is installed, in order to realize monitoring to slave computer.In the memory (hard disk) of host computer, be provided with following database:
Parameter library: the operational factor that slave computer is set;
Runtime Library: store the operational factor of set slave computer and the service data of slave computer;
Enviroline: the storage serial port be provided with data and memory time data;
History parameters storehouse: historical (day) supplemental characteristic of storage;
History run storehouse: historical (day) service data of storage.
As shown in Figure 3, the monitoring flow process of host computer is as follows:
1) operation beginning;
2) host computer data and the slave computer plane No. in the extracting parameter storehouse successively;
3) judge in the parameter library whether parameter has been set,, then withdraw from if do not have; If have, then enter following steps:
4) data in the extracting parameter storehouse form and send sign indicating number;
5) send " sending sign indicating number " to slave computer, and wait for the regular hour, as 1 millisecond;
6) wait for the answer signal (being the handset address information) that the reception slave computer is beamed back;
7) judge whether to receive with send sign indicating number in identical slave computer plane No.; If no, then enter step 8); If receive with send sign indicating number in identical slave computer plane No., then enter step 9);
8) whether judgement wait number of times and time have arrived setting value, if do not arrive, return step 6); If the wait number of times enters step 11) with time is up;
9) receive the data that slave computer sends;
10) judge whether the slave computer data that receive are effective, if invalid, enter step 11); If effectively, enter step 12);
11) get the next plane No. of parameter library, enter step 13);
12) effective slave computer data are stored in the Runtime Library;
13) judge that whether the plane No. in the parameter library has got, if do not got, returns step 2); If got, then enter following steps:
14) begin circulation from the first plane No. of stored data base, return step 2).
Slave computer in the air conditioner long-distance monitoring system of the present invention both can have been selected by the host computer centralized Control, also can select to be controlled voluntarily by the control device of slave computer.When the address of slave computer was set to 0, slave computer can't carry out the communication with host computer, and therefore, the running status of slave computer is controlled voluntarily by the control device of slave computer.When the setting of the address of slave computer was not 0, slave computer can carry out the communication with host computer, and the running status of slave computer is by the centralized Control of host computer.
As shown in Figure 4, the operational process of slave computer is as follows:
1) beginning;
2) judge whether the plane No. (slave computer address) that is provided with in the slave computer control device is 0, if, then enter step 3), if not, step 4) then entered;
3) press the single cpu mode operation, at this moment, the control device of slave computer self is effective, can operate the button of slave computer self control device, key information is stored in the memory of slave computer; Return step 2 then);
4) receive the data that host computer sends;
5) judge in the transmission sign indicating number of host computer whether gating signal is arranged,, then enter step 7),, then enter step 6) if having if do not have;
6) judge in the transmission sign indicating number of host computer whether this machine plane No. is arranged,, then enter step 7) if do not have; If have, then enter step 8);
