Core module, facilitates follow-up route to develop, and advances the star-like monitoring net of little area to develop to large-area Cellular Networks.
In order to solve above technical problem, the technical solution used in the present invention is as follows:
A kind of coal-field fire CC2530 node high-temperature data gathers and synchronizes dormancy control method, it is characterised in that described
Synchronization dormancy control method comprises the steps:
Step one, uses external clock chip PCF8563 to control clock as the synchronization dormancy of CC2530 node,
CC2530 node bottom abstract component is simulated two-wire serial bus I2C host-host protocol, utilizes described two-wire serial bus I2C passes
Transmission protocol realizes the nucleus module communication of external clock chip PCF8563 and CC2530 node；
Step 2, is divided into work phase T by the sleep interval cycle T of each CC2530 nodewWith rest period TsTwo rank
Section, sleep interval cycle T is more than node working cycle TwIn the range of arbitrarily can set by year, month, day, hour, minute
Fixed；
Step 3, as work phase TwDuring beginning, converge CC2530 node and common CC2530 node is respectively completed different
Task:
Converge CC2530 node and start network, read the time of external clock chip PCF8563, with the minor cycle t set
When carrying out the broadcast school in network-wide basis, complete the collection of data simultaneously and remotely send, due to prolonging of networking, data transmission etc.
Time, the working time ratio common CC2530 node length 1 of convergence CC2530 node sets～2 minutes；
Common CC2530 node finds the network that can add, and accepts to converge the school of CC2530 node broadcasts in network constantly

According to, after 1 representative, clock is along receiving data；Known by permutation and combination, serial synchronous output mode SPI have four kinds of clock polarity CPOL and
The mode of operation of clock phase CPHA combination, for ensureing that CC2530 node correctly communicates with MAX6675 chip, should have between the two
There are identical clock polarity and clock phase；Clock polarity is known by the serial synchronous output mode SPI sequential of MAX6675 chip
CPOL is 0, and clock phase CPHA is 1, accordingly the work schedule of serial synchronous output mode SPI on simulation CC2530 node, again
Claim shift pulse；
Step 4, data transmission and acquisition: the universal input output GPIO pin that described chip selection signal is corresponding is set low level, makes
MAX6675 chip operation, the chip selection signal produced at described CC2530 node and under described shift pulse acts on jointly, data are pressed
Position transmission, high-order front, low level is rear；After 16 bit data transmit, force the universal input output corresponding to chip selection signal
GPIO pin sets high, and prepares the transmission of next round data；To 16 bit data D received15~D0Resolving, extraction is effective
12 conversion data D14~D3, form readable temperature data.
2. a kind of coal-field fire CC2530 node high-temperature data as claimed in claim 1 gathers and synchronizes dormancy control method,
It is characterized in that: also include the step that described CC2530 node is packaged to be processed, to adapt to the harsh of high temp. monitoring
Environment, is protected by described CC2530 node.
