Description
Technical field
The utility model relates to railway infrastructure health status monitoring technologies.
Background technique
In recent years, with the development of technology of Internet of things, Along Railway infrastructure health status automatic monitoring is got over
Carry out more concerns.However Along Railway is usually located at field especially mountain railway, monitoring environment is relative complex, there is communication
The features such as signal is unsmooth, equipment installation and maintenance is difficult.Therefore a kind of wireless forms of communication is used, monitoring regional environment number is collected
According to that can not only reduce wiring, save the cost reduces equipment installation and maintenance difficulty, while will can also collect environment in real time
Data are uploaded to remote server by way of GPRS mobile network, and finally use for customer analysis.
Utility model content
Technical problem to be solved in the utility model is to be to provide a kind of railway monitoring data transceiver and data are received
Forwarding method reduces wireless data transmission packet loss and the bit error rate to solve field device difficult wiring to greatest extent.
The utility model solve the technical problem the technical solution adopted is that, railway monitoring data transceiver, feature
It is, including control unit and local area network wireless communication unit connected to it, wide area network wireless communication unit, data storage list
Member regularly sends judging unit and instruction transmission judging unit.
The workflow of the utility model includes the following steps:
A, judge whether following two conditions are true:
A1) whether current time is the time for meeting preset sending frequency, a2) whether receive the alarm from local area network and refers to
It enables,
If any establishment that the two is all set up or both, enters step b, enters step c if the two is all invalid；
B, signal data is received from local area network, sends signal data to remote server through wide area network after packing；If sending
It is successful then enter step c, signal data is stored in local storage if failure；
C, judge whether to receive the frequency conversion instruction from wide area network, if then changing preset sending frequency simultaneously according to instruction
Return step a enters step d if not；
D, judge whether there is the signal data for sending and saving after failure in local storage, if not just into return step a, if
It is to read and signal data and send again from local storage, then repeatedly step d.
Further, further include step c1: judging whether to receive the more new command of the program from remote server, if
Then enter more new procedures, if otherwise entering step d.
The utility model compared with prior art the advantages of be:
1, the utility model combination on-site data gathering device field monitoring region Wireless LAN, substitution pass through bus etc.
Wired mode carry out data collection, while uses be 433Mhz frequency attachment wireless communication channel, compared to 2.4GHz frequently
The Zigbee module of rate, barrier diffracting power is stronger, is more suitable for field work；
It 2, will be final by GPRS module after the utility model has collected area data collector data progress fusion treatment
Data are uploaded to remote server.An external GPRS module is connect compared to each collector, and data are uploaded to remote server
Mode, the utility model not only largely reduces the use of GPRS module, reduces construction cost, simultaneously because a monitoring
Work point corresponds to a GPRS module, and remote server data management difficulty is greatly reduced.
3, the utility model uses the active and passive wireless data collection mode combined, it is ensured that timely finds disaster report
Alert information.Under normal circumstances, the utility model collects monitoring region collector data using the method for timing, however ought wherein appoint
When numerical value overload alarm occurs for a collector of anticipating, the utility model will timely collect all collector data and be uploaded to long-range
Server.
Detailed description of the invention
Fig. 1 is the modular structure schematic diagram of the utility model.
Specific embodiment
Referring to Fig. 1.Railway monitoring data transceiver include control unit and local area network wireless communication unit connected to it,
Wide area network wireless communication unit, data storage cell regularly send judging unit and instruction transmission judging unit.
From hardware realization, the data collector of the utility model includes that CPU control module, memory extend out module, RF mould
Block, interface module, Voltage stabilizing module and power module.CPU control module and memory extend out module, RF module, interface circuit
Module, Voltage stabilizing module are connected.The Voltage stabilizing module is connected with power module.The interface module includes on-line debugging
Interface module, SD card memory module, RS232 serial port module.
In the transceiver course of work, need artificial access 10V~18V power supply to power module first, through voltage regulator circuit
After pressure stabilizing, stabilized power supply to other modules such as CPU control module are provided and are used.When CPU control module is started to work, default is fixed
When half an hour by RF module polls collect collected sensor to the collector of star-network from node, by data fusion
Afterwards, data are uploaded to by remote server by GPRS module.Remote server can be practical new to this by GPRS network simultaneously
Type GPRS module sends frequency conversion and uploads the instruction such as data, by GPRS module by the data received be sent to CPU control module into
Then row parsing realizes that changing poll star-network from node data and uploads the remote server time.
The utility model can not only active timed collection star-network slave node data, while star can also be received
Any one exceeded warning message of sensor values sent from node in shape network, and poll is all immediately after receiving alarm
It is uploaded to remote server after the collected Data Fusion of Sensor of node, realizes that the acquisition of first time data occurs for disaster.
The main application scenarios of the utility model are under the fields complicated environmental conditions such as Along Railway, massif, through GPRS module
The data of upload cause not uploading vulnerable to GPRS network swinging of signal.Data to ensure to be collected into are not lost as far as possible,
Data will can not be uploaded caused by network cause automatically to store to the SD card memory module of debug circuit, wait GPRS network extensive
After answering normally, the data for being stored in SD card are automatically uploaded to remote server again.
The utility model clock module calculates current time in real time, and can receive remote server by GPRS module and refer to
It enables, realizes clock alignment.
The utility model can realize online remotely updating program.On the server by compiled new procedures bin file, warp
GPRS network is respectively sent to GPRS module, stores after the parsing of CPU control module to memory and extends out module, it is waiting harvest it is all
After subpackage bin file, address check is carried out, finally new procedures bin file is copied to inside CPU control module in Flash.
The utility model uses the collector data based on the adjustable RF module collection star-network of 433Mhz.In order to more enough most
It may be decreased wireless data transmission packet loss and the bit error rate, using following form communications protocol format:
First three byte in agreement indicates order recipient's radio address and channel, is to send for accurately distinguishing order
The collector specified into star-network reduces packet error rate as ending from node, while using 2 byte check codes.
In terms of reducing and transmitting packet loss, the utility model and collector are all made of re-transmission side three times from the wireless data communication of node
Formula.
