News frequency point is configured, and different monitoring networks can be configured to corresponding communication channel, when multiple monitoring slaves access one
During system, for the ease of recognizing different monitoring slaves and its monitoring position, one kind is employed in this programme to multiple network lists
The mode of row address hierarchical planning is entered by unit, distributes an independent network number to each monitoring system, in same network number
Each monitoring slave, its node address is different, ensure that the independence of transmission channel from source, when there is multiple systems
During system, in order to prevent interfering in communication process medium frequency, we are divided to the frequency in 2400M-2483M, by which
It is divided into 24 different frequencies, the host and slave processors in same system, it is necessary to be only possible between the node under same communication frequency
Intercommunication.Adjacent networks in same working region, using different communication frequencies, cause to communicate to avoid interfering
Efficiency reduces.Monitoring main frame, the 2.4G modular units of slave, its hardware configuration is identical, for the ease of to monitoring main frame in system,
The network address of slave, node, communication frequency are allocated, and are provided with a net in monitoring main frame in systems, slave
Network dispensing unit, is allocated to the network address of module, node, communication frequency by host computer, and 2.4G wireless modules are received
Configuration information result is preserved in memory cell built-in within a processor.Realize the ground of wireless network segment in data transmission link
Location identification and configuration.
Identical due to monitoring slave, be identified by hardware identification mode at data acquisition end, each monitoring from
In machine, an address configuration unit is each equipped with, before monitoring slave is started working, which is configured on hardware, is passed through
Change its binary address coding, realize the data acquisition Address Recognition of monitoring slave.During data transfer, transmission
Just include hardware address information in packet, main frame is monitored by the information analysis in the packet to receiving, be somebody's turn to do
Monitoring slave Current hardware address information and the data message for collecting, monitor flow process and the monitoring main frame of slave data is activation
Data receiver flow process is as shown in Figure 3.In monitoring slave, processor is by the temperature information for receiving, CO concentration informations, combustible gas
Bulk concentration, smokescope information are packaged to data by the form of grid protocol requirement, are also wrapped in the packet of encapsulation
The internal state of the address configuration information containing the monitoring slave, data check information and monitoring slave, warning information etc..Data
After the completion of encapsulation, periodically data is activation is gone out by 2.4G wireless network modules, in wireless data sending link, processor is first
Configuration information of the first reading and saving in processor internal storage, and by configuration requirement to wireless transmission link in network ground
Location, node address, configured, then selected corresponding physical channel, the corresponding communication frequency in each physical channel, with
Monitoring main frame, monitoring slave in one system must be only possible to intercommunication between the node under same communication frequency.?
Adjacent networks in same working region, using different communication frequencies, cause communication efficiency to reduce to avoid interfering.Choosing
After selecting corresponding frequency, 2.4G wireless module automatic switchovers operating frequency is on the frequency, and returns an information to processor,
And log-on data sends, until processor inquires data is activation and finishes, a signals transmission is completed.
In wireless data receiving terminal, main frame is monitored by the network ground in the wireless transmission link same with monitoring slave
Location, node address, configured, then select corresponding physical channel, and log-on data receives process, different from monitoring slave
, monitoring main frame all the time be in data query reception state, by the network address, node address and communication frequency
Match somebody with somebody, all information on the frequency are compared, received, and make corresponding judgement.And monitoring result is sent to aobvious
Show unit, shown in real time, meanwhile, by CAN network, communicate information to instrument pack.
This utility model preferred embodiment disclosed above is only intended to help and illustrates this utility model.Preferred embodiment is simultaneously
Without all of details of detailed descriptionthe, it is only described specific embodiment also not limit the utility model.Obviously, according to this theory
The content of bright book, can make many modifications and variations.This specification is chosen and specifically describes these embodiments, is in order to preferably
