Example Embodiment

[0050] Example one

[0051] figure 1 Shows the system structure diagram of the indoor and outdoor master-slave clock satellite timing system provided by the present invention, figure 2 Shows the flow chart of the method for remote wireless software upgrade of satellite timing equipment provided by the present invention, image 3 Shows the flow chart of the method for transmitting the software upgrade program in unicast wireless communication provided by the present invention, Figure 4 It shows a schematic diagram of the packet structure of the unicast data packet provided by the present invention.

[0052] The method for remote wireless software upgrade of satellite timing equipment provided in this embodiment includes the following steps.

[0053] S101. The remote software upgrade special equipment and the satellite timing equipment obtain satellite standard time through satellite communication respectively, and update the local RTC time of the special equipment and the local RTC t...

[0075] Example two

[0076] Figure 5 Shows the flow chart of the method for transmitting the software upgrade program by multicast wireless communication provided by the present invention, Image 6 It shows the packet structure flow chart of the multicast data packet provided by the present invention.

[0077] This embodiment provides another method for remote wireless software upgrade of satellite timing equipment that is different from the first embodiment. The difference from the first embodiment is that: in the step S102, the remote software upgrade special equipment The steps for transmitting the software upgrade program to the satellite timing equipment according to the multicast wireless communication mode include the following.

[0078] S401. The remote software upgrade special device first enters the wireless communication sending state according to the local RTC time of the special device, and sends the multicast preparation preamble.

[0079] S402. The satellite timing de...

Example Embodiment

[0087] Example three

[0088] This embodiment provides a remote wireless software upgrade method for satellite timing equipment that can combine the advantages of both the first and second embodiments. The difference from the first and second embodiments is: remote software The upgrade dedicated device transmits the software upgrade program to multiple satellite timing devices in the same working state according to the multicast wireless communication mode, and transmits the software upgrade program to the satellite timing devices in a specific working state according to the unicast wireless communication mode.

[0089] For indoor slave clocks, because they are installed in various rooms in the room, and there are generally more of them, and the upgrade procedure of each slave clock is the same, so the multicast method is generally used to upgrade the software of more slave clocks. For outdoor master clocks, since there is generally only one master clock or multiple master clocks i...

Abstract

The invention relates to the field of clock satellite time service systems and discloses a method for conducting remote wireless software upgrading on a satellite time service device. According to the method, a special software upgrade device with satellite communication and wireless communication functions is used for conducting remote wireless software upgrading on the satellite time service device. Compared with a conventional software upgrading method, artificial on-site participation is not needed, software upgrading can be completed periodically and automatically, so that the upgrading efficiency can be drastically improved, the upgrading cost can be lowered, the satellite time service device cannot be further damaged, and thus the method is beneficial to long-period stable work of the satellite time service device and helps to conduct long-period unattended operation arrangement on the satellite time service device. Furthermore, the method also has the advantages that the method is low in power consumption, little in occupation of channel resources, high in success rate and easy to achieve, and the method is conveniently practically generalized and applied.

Description

Technical field [0001] The present invention relates to the field of clock satellite time service systems, in particular to a method for remotely wireless software upgrade of satellite time service equipment. Background technique [0002] Satellite timing equipment is a kind of equipment that can obtain satellite standard time through satellite communication, and can automatically update the local RTC (Real-Time Clock) time according to the satellite standard time to achieve synchronization with the satellite standard time. For example, a quartz clock with satellite timing function. Many existing satellite timing equipment are fixedly installed. At the same time, in order to improve the protection level, it is possible to seal the satellite timing equipment and other protective treatments. When it is necessary to upgrade the software of satellite timing equipment, the existing conventional method is to manually upgrade the software in the field by wired communication, which is n...
