Problems solved by technology

There are the following problems in the use of these two modes: a) the use of NTP mode requires a high quality level of the network communication environment, and is affected by changes in network routing and load, and the network transmission delay of NTP time statistics packets cannot be measured; b) NTP The time statistics message only gives the current absolute time message information, and cannot give the starting point of the current time. Affected by the network data transmission delay, the time statistics accuracy of the NTP time statistics message is not high; c) the Beidou timing combination is used Independent time service, through the second pulse and time code information, can perform high-precision time service on a single point, but in special cases, once the satellite signal is lost or damaged, the ground receiver cannot receive the normal second pulse and time code information, Therefore, it is impossible to achieve effective time information unification among the points.

Abstract

The present application provides a time service device, system and method, wherein the device includes: a receiving unit, used to process the received Beidou / GPS satellite signal, and output a signal in a specified protocol format; a main control unit, according to the Determine whether the satellite signal is valid according to the specified protocol format signal; if valid, output the first control signal; if invalid, output the second control signal; acquire and issue control instructions according to the external control signal; The signal is used to output the satellite timing signal; the autonomous timing output unit is based on the second control signal to output the time signal of the main equipment as the timing signal. This solution can guarantee high precision and accuracy, but also has high indestructibility and robustness, and provides reliable and effective time-based information for combat units in different battlefield environments.

Description

technical field [0001] This application relates to the field of network communication, in particular to a military timing device suitable for realizing the functions of absolute timing and relative timing when command and control vehicles at the brigade level and battalion level conduct centralized operations. Background technique [0002] In the process of networked operations of military equipment, it is necessary to align the nodes of unified operations in time and space in order to form a unified information field. When performing time-space alignment, each combat node needs to unify the time reference. [0003] At present, military equipment generally adopts the timing mode of connecting to the NTP network according to the requirements of the use scenarios, or the mode of connecting each single point to the Beidou timing combination for independent timing. There are the following problems in the use of these two modes: a) the use of NTP mode requires a high quality lev...
