Multimedia simulation electronic clock

Abstract

The invention relates to a multimedia simulation electronic clock with networking, advertisement publishing and multimedia information publishing functions. The multimedia simulation electronic clock is characterized in that an embedded type computer is used as a clock core, and a flat plate display screen is used as an electronic clock disc; the clock disc and pointers are simulated by an image processing technology, and the styles of the clock disc and the pointers can be switched and updated according to requirements; a structure of combining a simulation clock disc, simulation pointers and a three-dimensional true clock disc outer casing is adopted, and the appearance of the traditional clock is maintained; the original boundary of the electronic clock is broken through, the electronic clock can work in a server mode or a client mode, and a clock network system is established by a network technology; a time signal obtaining mode and a clock synchronizing mode which coexist in WIFI (wireless fidelity), Ethernet, global positioning systems and the like are adopted; the simulation clock disc can be switched into an advertisement and multimedia information publishing interface, and a multimedia file is played on the electronic clock or on the network on line; for overrun and emergency events of environment monitoring data, the system can automatically publish the informative or warning information.

Description

technical field [0001] The invention relates to a multimedia simulation electronic clock and an advertisement publishing carrier related to electronic technology Background technique [0002] The main technologies involved in electronic clocks include: movement, time and auxiliary information display, and timing calibration. [0003] 1. Main movement technology [0004] At present, the movement technologies of electronic clocks mainly include three types: quartz crystal movement, radio wave movement and all-electronic digital movement. [0005] (1) The quartz crystal movement is composed of two parts: mechanical transmission and electronic circuit. The quartz crystal oscillator replaces the traditional balance spring of the mechanical clock, so that the circuit generates an oscillation signal with a stable frequency, and obtains a much higher travel time accuracy than the mechanical clock. A stepping motor is used to convert electrical energy into mechanical energy to dri...

AI Technical Summary

Problems solved by technology

[0016] 1. The analog electronic clock with electromechanical combination has the disadvantages of large travel time error and high failure rate

[0017] 2. The disadvantage of fully electronic digital display clocks is that they do not conform to people's aesthetic habits for the appearance of clocks and watches.

[0018] 3. There are obvious defects in timing calibration

[0019] (1) One type is an electronic clock that has no standard time service at all and needs manual time adjustment

[0020] (2) The time service method adopted by the radio wave clock is easily affected by the receiving environment, weather and other conditions

Timing signals received on high-speed moving planes and trains will produce errors

[0021] (3) Wall clocks and desk clocks used indoors cannot receive the timing signal from the GPS

[0022] (4) The industrial clock system with master clock, secondary master clock and slave clock structure is restricted and limited in terms of installation and use, maintenance management, system cost and system scale due to the use of dedicated wired methods

[0023] (5) The electromechanical movement adopts the time tracking method to synchronize the clock, which is slow and time-consuming

[0024] 4. Without the foundation and conditions of network technology, it is impossible to build a watch network system through networking

[0025] 5. There is no function of publishing multimedia information and interacting through the network
