and determining the connection state of a transmission channel between the edge acquisition server and the data transmission equipment based on the time delay and the data transmission rate.
Specifically, referring to fig. 3, a method flowchart for determining a connection state of a transmission channel between an edge collection server and a data transmission device based on a time delay and a data transmission rate is disclosed in an embodiment of the present invention, where the method includes:
step S101, judging whether the time delay is not less than the first time period and the data transmission rate is less than the first rate, if yes, executing step S102, and if no, executing step S103.
The value of the first period of time is determined according to actual needs, for example, 1s, which is not limited herein. The value of the first rate is determined according to practical needs, for example, 10kbps, and the present invention is not limited herein.
Step S102, determining a connection state between the edge collection server and the data transmission device as a first connection state.
The first connection state characterizes an unstable connection between the edge collection server and the data transmission device, at which point the data transmission device may attempt to establish a connection with the edge collection server.
Step S103, continuously judging whether the time delay is smaller than the first time period and not smaller than the second time period, and simultaneously, judging whether the data transmission rate is not smaller than the first rate and smaller than the second rate, if yes, executing step S104, and if no, executing step S105.
The value of the second period of time is determined according to practical needs, for example, 0.2s, which is not limited herein. The value of the second rate is determined according to practical needs, for example, 50kbps, and the present invention is not limited herein.
Step S104, determining a connection state between the edge collection server and the data transmission device as a second connection state.
And the second connection state characterizes that the data transmission equipment only receives the operation state data of the monitoring equipment, which is acquired and transmitted by the edge acquisition server.
When the connection state between the edge collecting server and the data transmission equipment is the second connection state, the limited connection is judged, the edge collecting server only transmits the operation state data of the monitoring equipment of the embodiment, so that a land user can judge the state of the monitoring equipment, and when the monitoring equipment is abnormal based on the state of the monitoring equipment, the maintenance is carried out in the sea.
Step S105, continuously judging whether the time delay is smaller than the second time period and not smaller than the third time period, and simultaneously, whether the data transmission rate is not smaller than the second rate and smaller than the third rate, if yes, executing step S106, and if no, executing step S107.
The value of the third period of time is determined according to practical needs, for example, 0.1s, which is not limited herein. The third rate may be determined according to practical needs, for example, 512kbps, and the present invention is not limited thereto.
Step S106, determining that the connection state between the edge collection server and the data transmission equipment is a third connection state.
And the third connection state characterizes that the data transmission equipment only receives the operation state data and the edge characteristic data of the monitoring equipment, which are output by the edge acquisition server.
When the connection state between the edge collecting server and the data transmission equipment is the third connection state, the connection between the edge collecting server and the data transmission equipment is determined to be general connection, and only the operation state data and the edge characteristic data of the monitoring equipment are transmitted between the data transmission equipment and the edge collecting server.
Step S107, continuously determining whether the time delay is smaller than the third time period, and whether the data transmission rate is not smaller than the third rate, if yes, executing step S108, and if no, executing step S109.
Step S108, determining that the connection state between the edge collection server and the data transmission device is a fourth connection state.
And the fourth connection state characterizes that the data transmission equipment can receive the operation state data, the edge characteristic data and the edge original data of the monitoring equipment output by the edge acquisition server.
When the connection state between the edge collecting server and the data transmission equipment is the fourth connection state, the connection between the edge collecting server and the data transmission equipment is determined to be normal connection, and the operation state data, the edge characteristic data and the edge original data of the monitoring equipment can be transmitted between the data transmission equipment and the edge collecting server.
Step S109, determining a connection state between the edge collecting server and the data transmission device as the first connection state.
In summary, the invention adopts different data transmission schemes according to different connection states between the edge acquisition server and the data transmission equipment, thereby realizing self-adaptive transmission of data, reducing power consumption and improving data transmission accuracy.
In the field of industrial control and measurement, monitoring, control and management of equipment, each subsystem needs high-precision time information for fault alarm and log information so as to perform fault location and performance analysis, but the initial design of an IP network and an ethernet network does not consider synchronization problems. Currently, network Time Protocol (NTP) is commonly used, using software time stamps to achieve accurate time synchronization, ranging from 100 microseconds to 100 milliseconds or more. Practical use has shown that the accuracy of this technique can only reach a few hundred milliseconds or even seconds, usually due to network delays, hardware, operating systems, oscillator drift due to changes in ambient temperature, and time intervals due to time updates.
Therefore, referring to fig. 4, a schematic diagram of time synchronization of a cabin edge collecting server and a tower bottom edge collecting server is disclosed in an embodiment of the present invention, where the cabin edge collecting server and the tower bottom edge collecting server each acquire first standard clock signal information from a geosynchronous satellite in a global navigation satellite system GNSS (Global Navigation Satellite System ), time of the cabin edge collecting server and the tower bottom edge collecting server are synchronized with an atomic clock on the satellite, delay from different sensors to the edge collecting server is ignored, and time of the edge collecting server is recorded.
The GNSS may be GPS, beidou, etc.
In addition, the time check and redundancy configuration is carried out between the cabin edge collecting server and the tower bottom edge collecting server in a Network Time Protocol (NTP) mode. Because the data transmitted by the 4G/5G base station is also synchronized by GNSS geosynchronous satellites, the time synchronization precision under different transmission modes such as wired/wireless (WiFi)/4G/5G and the like is improved, and the millisecond level can be reached.
Finally, it is further noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
