Arranged between wire/radio network communication interface and each wireless access point using multilink, multilink arrangement
Refer to utilize two or more fire walls with brand flow-through number to form the/function of redundancy that backups each other in access point, can
More preferable reliability is provided.The raising of communication reliability comes from the use of multilink, while is added using multilink
Bandwidth, so that performance is lifted.Therefore network can be protected to avoid the risk for causing network interruption because of Single Point of Faliure.
Multi-link redundancy is played in multiple public network operators（ISP）Between failure transfer, Network Access Point dispose it is more
Platform equipment forms backup/redundancy, and when a wherein device fails, data, which will be switched in an other equipment, to be continued
Transmission, but also the superposition enhancing of equipment performance can be done.Network topology is shown in Fig. 3：
Multiple be connected in LAN carries out load balancing, and internet is connected and is optimized according to transmission speed.Pass through detection
With the connection of server, the most fast connection of feedback speed is preferentially transmitted.Therefore, integrated data throughput will much surpass
Cross the unstable single connection of a service performance.
After main control device breaks down transfer, backup main control device will be replaced into as main control device.Master control originally
Equipment will restart, and rejoin system as backup main control device.
What backup/redundancy of wireless network was taken is the mode of overlapping covering, each equipment detection terminal is at least located
In two wireless access point（AP）Effective coverage range in.All wireless access point configure identical SSID and password, eventually really
Protect the reliable of connection.
Wire/radio network communication interface uses error detection and retransmission mechanism, in common network transmission error detection
Basis on add additional verification rule, to ensure that data are relatively reliable.
System connection mode between equipment detection terminal, management platform and high in the clouds includes equipment detection terminal connection cloud side
Formula, equipment detection terminal connection management flat-bed format connect cloud platform mode with management platform.
Management platform includes dynamic configuration module and calibration module, and the regular tabulating equipment detection terminal of dynamic configuration module is adopted
Each device data and diagnostic result of collection, and according to default device type and environmental parameter automatic decision device data and diagnosis
As a result deviation and reasonability, are prompted when there is relatively large deviation and are carried out by default calibration strategy in calibration module
Calibration, is issued to each management platform and each equipment detection terminal after calibration.
Detection terminal is connected to collected equipment by the present embodiment by taking modbusRTU is communicated as an example, is placed in configuration shape
State, another port are connected to host computer, running configuration software.Connection with host computer can be connected by serial ports, also may be used
To be connected by network remote.See Fig. 4.
Serial communication between equipment detection terminal and equipment identifies that specific method is：
S1, poll judge whether the baud rate of serial communication and the data bit of character and check bit are correct；
S2, be polled the request in the data frame of serial communication according to modbusRTU communications protocol verification, and verification is correct
Afterwards, then by the function code in data frame serial communication parameter is verified；
S3, find out the acknowledgement frame matched with request, and request is directly sent to it, and is tested respectively using stop position 1 and 2, if returning
It is multiple correct, you can stop position number to be confirmed, so as to draw the complete parameter of serial communication.
S4, according to the corresponding register address of acquisition request, then obtain corresponding equipment by parsing register address and believe
Breath.
Serial communication between equipment detection terminal and equipment is in units of a character, and character is started with start bit, tightly
The lowest order of data word is connect, data word has 7-9 data bit, is terminated with the highest order of data word, immediately check bit after data bit,
Check bit is a kind of in no parity check position, odd parity bit or even parity bit, is finally stop bits, stop bits is 1 or 2 stop position；
The character data frame format of serial communication is as follows：
1 start bit
7th, 8 or 9 data bit
No parity check position, odd parity or even parity bit
1 or 2 stop position
Detection terminal ignores the 2nd stop position；The baud rate scope of serial communication is 9600-115200bps, wherein common be
Totally 6 kinds of 9600bps, 14400bps, 19200bps, 38400bps, 57600bps and 115200bps.First ignore stopping during detection
Position number, therefore the parameter of serial communication share 54 in combine.
In step S1, baud rate, data bits and even-odd check will be received and be set to different values, single character is taken turns
Ask.When there is no during mistake, you can be tentatively judged as that baud rate, data bits and even-odd check are correct.
In step S2, the data frame of modbusRTU communications protocol includes request and response, a request originate in 3.5
The information frame of bytesfree, immediately 8 bytes, rear 2 bytes of information frame are CRC checks, are also finally 3.5 bytesfrees.
By identifying before and after frame not less than the free time of 3.5 bytes, the information frame of 8 bytes is selected, if CRC check is correct, then is sentenced
Second byte of disconnected information frame（That is function code）Whether it is 1,2,3,4,5,6 verification communications parameters.
Fig. 5 is the example for the data frame that 19200 baud rates are obtained by poll, this is one and station number 1 is read to deposit
Device 71（47h）~76（4Ch）Claim frame.
In step S3, for 9600 minimum baud rate, the frame data time includes front and rear free time, about 0.09 second.
If there are data frame transfer, the most long a cycle of poll about 5 seconds always on interface.But actually often not deposit always
In data frame, it is also possible to which the reply data frame of modbus slave stations is long, therefore the time waited is longer.
The method parsed in step S4 is register address to be carried out individual data 16BIT respectively and Double Data 32BIT is adopted
Collection, reconvert carry out contrast judgement into decimal floating point number.
An error range is set during contrast, the numerical value in this error range will be labeled.Can also be automatically to every
A register is contrasted, and is judged again after being saved in file.
The advantage of the invention is that：
1. using control chip of the microcontroller as detection terminal, not only meet the requirement of equipment health control detection, Er Qiejian
Surveying terminal can be communicated in a manner of directly realizing WebService or HTTP+JSON on the microcontroller of no operating system with high in the clouds,
Without special configuration server, cost is effectively reduced.
2. configuration is integrated with all functions in detection terminal, management platform, high in the clouds, it is combined into so as to freely connect
System.
3. signal interference in data transmission procedure is efficiently solved using multilink arrangement, error detection and retransmission mechanism
The problem of.
4. the system compatibility is high, the signal communication agreement of all types of equipment can be parsed, realizes having for each device data
Effect collection.
