Description
Technical field
The present invention relates to field of communication technology more particularly to it is a kind of detect multi-path serial data collision method and device,
Equipment.
Background technique
In certain industries such as power generation industry, it will use various fortune on a large amount of miniature instrument detection or monitoring production line
Row data, miniature instrument is not high to communication bandwidth requirement, but to it is central controlled require it is very high, that is, require a controlling terminal or
Control centre's computer can be communicated with multi-channel long measuring instrument simultaneously.
Under this application scenarios, it is desirable to realize the communication technology of point-to-multipoint.Point-to-points data communication is more typical
Application scenarios are realized using communication protocol, and communication scenes such as high for bandwidth requirement use the network protocol of ether interface；
For the not high scene of bandwidth requirement, using RS485, CAN bus etc., point-to-multipoint delivery is realized by master slave mode.
And as power industry, the miniature instruments of monitoring device operation data are much used for, data communication interface to be usual
Using RS232 serial ports etc., point-to-points control can not be realized by network protocol or master slave mode.In this case,
More common solution is, by configuring remote-terminal unit (English: Remote Terminal Unit, abbreviation: RTU),
Guarantee only have a RTU to occupy communication channel in synchronization, the output data of other RTU is full 0 or complete 1, then to control
Multichannel RTU data do mutually and (non-communicating RTU exports complete 1) or mutually or (non-communicating RTU exports full 0) operation, realizes most strings
The merging of mouth data, and merging data is transmitted to control PC.It is communicated and Controlling model is as shown in Figure 1.
As shown in Figure 1, after multichannel RTU serial data is ANDed or ORed operation on distal end or proximal end access device,
It is transmitted to control centre's computer.Although being configured to RTU, in use, in order to improve the reliability of data communication,
Data need to be detected with the presence or absence of conflict, the data for not communicating RTU output such as are not full 0 or complete 1, then the circuit-switched data
It is wrong, if user can not take measures to the wrong data obtained in control centre's computer without detection means.
For multi-path serial data with the presence or absence of the detection of conflict, currently existing scheme is the output data by configuring RTU,
The RTU output data in communications status is required to have the communication frame format of frame head, data, check value, access device will be located
After the RTU data of communications status merge with the RTU data of other non-communicating states, it is sent into control centre's computer, in control
Data frame is verified on heart computer, if the check value that the transmission data check value and data frame that calculate in real time carry is not
It is equal, then it is assumed that data have conflict.But data are verified on control centre's computer, not can determine which platform
Mistake has occurred in RTU data；The detection method relies on RTU and has specific frame data output format, is just able to achieve verification, can not
Accomplish versatility.

Specific embodiment
Fig. 3 is a kind of flow diagram of method for detecting multi-path serial data collision provided in an embodiment of the present invention, should
Method the following steps are included:
S101 caches the multi-path serial data, every road serial data includes multiple when receiving multi-path serial data
Bit.
The multiple sensors or the collected various operation datas of equipment for being mounted on remote scene need while being sent to control
Multiple sensings of remote scene are arranged in the device of central computer processed, the detection multi-path serial data collision of the embodiment of the present invention
Between device or equipment and control centre's computer, which can be remote access device, is also possible to proximal end access and sets
It is standby, flexible deployment, the access device it can be router etc. according to demand.Its multi-path serial data communication and Controlling model
Still as shown in Figure 1.
The multi-path serial data that detection device receives multiple sensors of remote scene or equipment is sent, first by multichannel
Serial data is cached, and each circuit-switched data is all 0/1 bit (English: bit) stream in storage, and each circuit-switched data includes more
A bit.
In order to enable multiple sensors or equipment and the control centre's computer of remote scene to realize point-to-multipoint delivery, lead to
