Description
Technical field
It is more particularly to a kind of to be based on 433MHz wireless self-networking methods the present invention relates to technical field of data transmission.
Background technology
At present, the smart home trend development to advance by leaps and bounds in recent years, major technique in the market be ZigBee,
Bluetooth, WiFi, they are all based on 2.4G frequency transmitting, and transmission range is near.WiFi is should during current 2.4G is wirelessly transferred
A kind of most technologies, it is compared with Bluetooth technology, not only has higher transmission speed, while has high good transmission
Distance, under the environment of spaciousness, it can farthest transmit 200 meters.But the greatest problem that WiFi faces is that security is low, and power consumption
Greatly, long-distance transmissions cost is higher, networking is complicated, it is difficult to meet that building, cell, market etc. are adjusted the distance the place for requiring high.Phase
Anti-, open field, for 433MHz transmission range farthest up to thousands of rice, ability through walls is strong, design is simple, low in energy consumption, can be fast
Fast networking, wide coverage, without using authorize limitation, in the absence of the interference between other frequency ranges.But on Vehicles Collected from Market
Mostly it is unidirectional, single-channel 433MHz wireless data transmissions.
The content of the invention
Therefore, for it is above-mentioned the problem of, the present invention propose after a kind of networking reliable network stabilization, two-way communication, low-power consumption,
Networking is simple, cost is low based on 433MHz wireless self-networking methods.
To solve this technical problem, the present invention takes following scheme：One kind is based on 433MHz wireless self-networking methods, by leading
Structure networking carries out data exchange transmission automatically between machine and multiple equipment node；
Main frame：
S1, power-up initializing, bottom layer driving and wireless module register are configured, main frame is in reception state；
S2, connection intercepted into opening, obtains the link information of device node, i.e., device node can broadcast transmission add request and even
Connect request, after the addition token of device node and the addition token of main frame match, main frame send containing connection token should
Information is answered to device node, after the connection token of device node and the connection token of main frame match, device node and main frame
Link ID corresponding to obtaining respectively；
If S3, the packet for receiving device node are handled in interrupt thread, corresponding port is matched, enters corresponding line
Handled in journey, while main frame can be sent information in respective links table according to the different linking ID with each device node, it is each
Device node can be by each linking link information corresponding to ID extractions；
If S4, being not received by information, the frequency of respective channels can be set by frequency hopping channel table, pass through the RSSI value to channel
Assessed, if RSSI value exceeds predetermined range, automatic jump to next channel；
Device node：

S2, device node broadcast transmission to main frame, which add, asks, and the frequency of respective channels can be set by frequency hopping channel table, send
It is preceding progress scan channel, locking and frequency modulation to and the same channel of main frame, if receive main frame answer signal, be then obtain connection
Token enters next step, otherwise continues broadcast transmission and adds request to main frame；
S3, device node obtain link ID if successful connection, otherwise continue to send out according to connection token broadcast transmission connection request
Connection request is sent to main frame；
S4, device node have information in corresponding connection table, and main frame can be by linking the extractable corresponding link informations of ID；
S5, by acknowledgement mechanism it can determine whether data are received by main frame, if device node does not receive response, after repeatedly sending
Response is not received still, then stops sending；
If S6, present channel block, avoid conflicting using CSMA, repeatedly send failure after, judge Host Channel whether saltus step, be
Then frequency hopping is extremely and main frame is in same channel；
Each device node and main frame carry out two-way communication by linking ID.
Further, in addition to more than one relay station, each relay station can store each device node of forwarding and main frame
The packet of transmission is used for extended network transmission range.
Further, the relay station is the equipment or equipment section that storage forwards each device node and host information
Point.
Further, the device node works as external trigger automatically into sleep state in the case of without external trigger
Enter wake-up states afterwards, after data have been sent and automatically switch to sleep state.
Further, each device node has oneself unique address, and main frame can pass through the unique address of device node
Carry out data transmission to search for corresponding chained list.
Further, if in main frame also settable S5, main frame is not received by heartbeat packet in certain time, judgement is set
Slave node is offline, presence, offline or low electricity condition of the main frame by heartbeat packet care testing device node；And device node
S7, timing transmission heartbeat packet are then correspondingly arranged to main frame, if main frame is repeatedly unresponsive, judges main frame power down or offline, equipment
Node can extend heartbeat packet transmission；
Further, main frame receives when packet is handled in interrupt thread in S3 by length, address filtering, CRC
Verification screening data available bag, by the port number of read data packet, enter in corresponding thread and handle.
Further, networking success aft engine also carries out S6, main frame itself and automatically saves link table information after power down in real time
It can recover network automatically when upper electric again；And device node then also carries out S8, device node automatically saves link table information and pawned in real time
It can recover network automatically after going up electricity again after electricity；The preservation chained list of main frame and device node comprising the connection status of node, address,
Connection ID, transmission, receiving port information.
Further, effective predetermined value of RSSI value is -105dBm--74dBm in the S4 of the main frame.
By using preceding solution, the beneficial effects of the invention are as follows：Enter by using main frame and multiple equipment node
Row networking, using low-power consumption as target, detected using channel confliction, be fast frequency-hopped, two-way communication technology, improving the stabilization of system
Property and security, by further setting, that is, set relay station, can effective extended network transmission range, the setting of heartbeat packet,
So that main frame can care testing device node state, judge that device node is online, offline and low electricity condition, same device node
Also can be by whether obtaining response to judge that main frame is online, off-line state, to take corresponding measure to enter low power consumpting state, simultaneously
Device node sets sleep state to reduce power consumption；By setting main frame and device node to automatically save chained list in real time, can be achieved
Electricity preserves, and upper electricity is automatic to recover network connection, saves the time, further reduces power consumption；The service life length of building network equipment,
