Specific embodiments of the present invention have been shown by way of the above drawings and will be described in more detail below. The drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but rather to illustrate the inventive concepts to those skilled in the art by reference to the specific embodiments.
Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.
Embodiments of the present invention are described in detail below with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present invention provides a wireless electronic control timing system, including: the timing source determining module 1, the time synchronizing module 2, the timing task setting module 3 and the timing display module 4.
The time service source determining module 1 is configured to determine an optimal time service source combination from the time service source candidate pool based on a preset time synchronization period, so as to obtain a target time service source combination.
When the timing task is realized through the local clock source, the high-precision clock source is expensive in cost, so that the common local clock source has larger errors and cannot realize the high-precision timing task. Therefore, in order to eliminate these errors, the prior art generally uses a network time synchronization method to perform time synchronization on the timer, so as to ensure that the time of the timer is accurate, but this method is only applicable to a common scenario, and when high-precision timing is required, the existing timer cannot achieve high-precision timing due to factors such as delay of a transmission path and local clock error. Therefore, in this embodiment, the time service source determining module 1 determines a plurality of target time service sources, and by using the combination of the target time service sources, not only can high-precision time synchronization be achieved, but also time errors generated when the communication link receives interference can be avoided, and time precision of the timer can be effectively ensured and improved, so that high-precision timing is achieved.
Optionally, the number of time service sources in the target time service source combination can be set manually according to actual requirements, and the number of time service sources can be determined through experiments. Besides determining the optimal time service source combination from the time service source candidate pool, the target time service source combination can be determined at random directly according to the number of time service sources, and the aim of the application can be achieved.
The time synchronization module 2 is configured to perform time synchronization on a local time source based on the target time service source combination, so as to obtain a standard clock.
After the target time service source combination is determined, the local time source can be updated by adopting the target time service source combination, so that the local high-precision time is realized. Since the objective of determining the target time service source combination is to eliminate the influence caused by the communication link as much as possible, but in general, it cannot be known that the communication link is affected, and therefore, in this embodiment, the local time source is synchronized by adopting a weighted synchronization manner, so that the influence of a certain communication link can be reduced as much as possible.
When the standard time is acquired, delay in the wireless electronic control timing system can be ignored, so that the standard time can be used as a reference in the timing process, and the tasks of instant timing, and the like can be realized.
The timing task setting module 3 is configured to receive a man-machine interaction instruction for setting a timing task in a wireless manner, set the timing task according to the man-machine interaction instruction, and execute the timing task based on the standard clock.
Optionally, in addition to the man-machine interaction instruction obtained in a wireless manner, the man-machine interaction instruction can be obtained in a wired manner, and the man-machine interaction instruction can be obtained in a hardware interaction manner, so that the method is suitable for various timing application scenes. It should be noted that, the man-machine interaction instruction is only a preferred timing manner in this embodiment, and may trigger a timing task through a certain signal.
When an instant timing task is generated, timing can be started immediately, trigger time is recorded, trigger path delay is calculated, and the timing starting time is obtained after the trigger time minus the trigger path delay. The calculation of the timing end time is the same as the calculation of the timing start time, and the embodiment will not be described in detail.
When a timing task is generated, a timing task is set by the timing task setting module 3, and a standard clock is used as a reference, and after the time is reached, the timing task is triggered.
The timing display module 4 is configured to display a timing result in a visual manner after the timing task starts to be executed.
The visualization mode is mainly local visualization, namely, the timing process and the timing result are displayed through a display. The timing result can also be displayed through linkage visualization, namely, the timing result is displayed on other equipment, platforms or terminals in a synchronous mode.
According to the wireless electronic control timing system provided by the invention, the time service source determining module 1 is arranged to determine the reference time service source, so that an effective reference time service source can be selected, and then the time synchronization module 2 is arranged to perform clock synchronization based on the reference time service source, thereby generating effective, reliable and high-precision standard time, providing effective support for high-precision timing, and finally, the task setting module and the timing display module 4 are arranged to realize timing tasks and timing display functions, so that the timing tasks are applied to various scenes.
In one possible implementation, the time service source candidate pool includes a plurality of Beidou satellite time service sources and a GPS (Global Positioning System ) satellite time service source.
It should be noted that, the Beidou satellite time service source and the GPS satellite time service source are only preferred modes of the embodiment, and when general precision is required, different servers can be adopted as time service sources, so that the reliability of the timing system can be effectively improved through the weighting method of the embodiment.

9. The radio controlled timing system of claim 8, wherein time synchronizing a local time source based on said target time service source combination to obtain a standard clock, comprises:
acquiring a target time service source combination as a basis, determining a target comprehensive time service error, and according to the comprehensive target time service error;
and correcting the local clock source according to the comprehensive target time service error every time a clock correction period, so as to realize time synchronization and obtain a standard clock.
10. The system according to claim 9, wherein the step of receiving a man-machine interaction instruction for setting a timing task in a wireless manner, setting the timing task according to the man-machine interaction instruction, and performing the timing task based on the standard clock, comprises:
receiving a man-machine interaction instruction for setting a timing task in a wireless mode, and setting the timing task according to the man-machine interaction instruction;
And judging whether the timing task needs to be executed immediately, if so, executing the timing task immediately, taking the time output by the current standard clock as the timing starting time, otherwise, waiting for the arrival of the target time corresponding to the timing task, and executing the timing task according to the standard clock.
