Problems solved by technology

However, the verification of the data on the control center computer cannot determine which RTU data has errors; this detection method relies on the RTU having a specific data output frame format to achieve verification, which cannot be universal

Embodiment Construction

[0031] image 3 A schematic flowchart of a method for detecting multi-channel serial data conflicts provided by an embodiment of the present invention, the method includes the following steps:

[0032] S101. When multiple channels of serial data are received, buffer the multiple channels of serial data, where each channel of serial data includes multiple bits.

[0033] Various operating data collected by multiple sensors or equipment installed in the remote site need to be transmitted to the control center computer at the same time. The device for detecting multi-channel serial data conflicts in the embodiment of the present invention is set between multiple sensors or equipment in the remote site and Between the control center computers, the detection device can be a remote access device or a near-end access device, which can be flexibly deployed according to requirements, and the access device can be a router or the like. Its multi-channel serial data communication and cont...

Abstract

The embodiment of this invention discloses a method for detecting a conflict of multipath serial data, and a device and equipment. The method comprises the following steps: performing statistics on the number of 1 or 0 of the data with same bit in cached multipath serial data; if the obtained number of 1 or 0 of the data with anyone same bit in the multipath serial data is not less than two, determining the conflict of the multipath serial data. By adopting the method, the data conflict can be detected without a data frame format of the communication; the method requires no use of a complex calculation to achieve the detection of the multipath serial data conflict conveniently and reliably.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and equipment for detecting multi-channel serial data conflicts. Background technique [0002] In some industries such as power production, a large number of small instruments are used to detect or monitor various operating data on the production line. Small instruments do not require high communication bandwidth, but high requirements for centralized control, that is, a control terminal or The control center computer can communicate with multiple remote monitoring instruments at the same time. [0003] In this application scenario, point-to-multipoint communication technology is required. The more common application scenarios of point-to-multiple data communication are realized by using communication protocols. For example, the network protocol of Ethernet interface is used for the communication scenarios with high bandwidth requirements; for the scenari...
