Illustrate as follows:

The frame format that at first defines water heater, remote controller wireless transmission data is as shown in table 1:

Table 1

Synchronous head

The equipment word

Identification code

Data

Wherein the synchronous head field is the FF of 5 bytes, 00 of a byte;

Equipment word field is a device name, and can establish 5A is water heater, and A5 is a remote controller;

The identification code field is water heater and remote controller pairing password, can be defined as 1 as required to a plurality of bytes, and when identification code was 3 bytes, described identification code quantity had more than 20 hundred million pairs of pairing passwords, does not almost have the possibility that repeats.

Data field is the data format of water heater and remote controller exchange, the data of water heater emission, the content of data field is the water heater temperature value, status informations etc. are two bytes, and the data of remote controller emission, the content of data field is control information, as heating-cooling, key informations such as open and close are a byte.

With reference to figure 5, illustrate that remote controller receives the control flow of data:

In step 51, begin to receive data, whether have synchronization character, if any synchronization character, then enter step 52 if detecting communication channel, otherwise continue to detect;

In step 52, further the judgment device word still is from other remote controllers according to equipment word judgment data from water heater, if judged result is that data are from other remote controller, then return step 51, continue to detect, then enter step 53 if judged result is from water heater;

In step 53, detect identification code, if identification code meets the pairing water heater, then think valid data with the water heater transmission of this remote controller pairing, enter step 54,, think that then described data are data of other water heater remote controller transmission if identification code does not meet the pairing water heater, then return step 51, continue to detect;

In step 54, remote controller is analyzed the data that receive, and shows corresponding situation according to data content.

The flow process that remote controller sends data is similar with reception.

When wherein sending data, whether if remote controller obtains push button signalling, then detecting communication channel has synchronous head, if have, then be judged as other water heaters and launch, wait for, in case there is not synchronous head, then represent the communication channel free time (on the frequency of using), begin to launch data immediately.

In addition, during water heater working, the data transmit-receive of corresponding control device of wireless is identical with remote controller in the water heater, with reference to figure 6, receives the Data Control flow process and underdraws as follows:

In step 61, the monitoring communication channel is to receive/to send out data earlier for the wireless data transceiving circuit, and communication control circuit (being single-chip microcomputer) analysis receives data, as has detected synchronous head, then enters step 62, otherwise continues to detect;

In step 62, the checkout facility word,, does not then deal with if be judged as from other water heaters from other water heaters or from remote controller according to equipment word judgment data, if be judged as data from remote controller, then enters step 63;

In step 63, detect identification code, if identification code does not meet the pairing remote controller, then return step 61, continue monitoring, if identification code meets the pairing remote controller, then think to enter step 64 with the valid data of the remote controller transmission of water heater pairing, receive described data, by water heater controller the data that receive are analyzed, and carried out corresponding actions, as rising according to corresponding, cooling, the executing agency of switch order control water heater carries out corresponding actions, if identification code do not meet, then think to belong to the data of remote controller transmission of other water heater, do not deal with.

Described control device of wireless sends the same remote controller of flow process of data, also according to synchronous head, judges whether to launch for other water heaters, if, then wait for, in case there is not synchronous head, then represent channel idle (on the frequency of using), begin to launch data immediately.

It is above-mentioned that only the present invention will be described with preferred embodiment, non-so promptly limit to interest field of the present invention, therefore, under the situation that does not break away from inventive concept, the equivalence that all utilizations specification of the present invention and accompanying drawing content are done changes, and all reason is with being contained in the claim scope of the present invention.
