Embodiment 1
[0047] In this embodiment, a structural representation of a time service terminal system in a portable high-precision time service device and a time service method of the present invention is provided, as shown in figure 1 shown.
[0048] From figure 1 It can be seen that a time service terminal system in this embodiment includes a control and signal processing module, a frequency source module, an interface module, a human-computer interaction module and a power supply module;
[0049] Among them, the control and signal processing module is the core part of the present invention, which realizes the two core functions of timing and self-calibration; the frequency source module provides clock reference for the control and signal processing module; the interface module is compatible with various physical interfaces of the timing equipment; The human-computer interaction module provides a good interactive interface with the user; the power supply module supplies power to each mo...
Embodiment 2
[0064] This embodiment mainly describes the specific steps of two core functions realized by the present invention: time service and self-calibration function.
[0065] Wherein, the core idea of the time service function is: the time service device generates a pulse cycle signal with a period of 1 second, which is provided to the time service device as a time reference; at the same time, the year, month, day, The data frames of absolute time information such as hours, minutes, and seconds are sent to the time-serving device. The specific implementation steps are as follows:
[0066] Step 1) Connect two or more timing terminal systems to each other through interface modules, complete the self-calibration process, and obtain a unified time reference;
[0067] Step 2) Connect each time service terminal system in step 1) to each time service device through the interface module. When the time service terminal system completes self-calibration and connects with the time service te...
Embodiment 3
[0084] More specifically, a time service terminal system in Embodiment 3 includes a time service main module, a rechargeable lithium battery and a protective casing, wherein the internal structure diagram of the time service main module is as follows Figure 4 Shown; The exterior design of embodiment and the design of protective casing are as Figure 5 shown. From Figure 4 It can be seen from the figure that the timing main module includes control and signal processing module, frequency source module, interface module, human-computer interaction module and power supply module; the control and signal processing module consists of Spartan-6 series FPGA, STM32 series microcontroller, button battery and their The main part of the frequency source module is a high-stable constant temperature crystal oscillator; the interface module is composed of RS422 interface, switch interface and 1553B interface; the power module is composed of rechargeable lithium battery, lithium battery ch...
