The invention discloses a wireless frequency modulation turret clock time telling control system, and belongs to the technical field of clock towers, the wireless frequency modulation turret clock time telling control system comprises two clock towers and an audio signal sending device, the number of the clock towers is two, the two clock towers are connected through signal feedback, and the output end of the audio signal sending device is in wireless signal connection with the input ends of the clock towers. According to the invention, an audio signal source generation module, a frequency modulation coding module and a wireless frequency modulation frequency emission module are arranged, the audio signal source generation module generates an audio signal, the frequency modulation coding module carries out coding and frequency modulation on the audio signal, and the signal frequency is controlled between 76.0 Mhz and 86.0 Mhz; meanwhile, the wireless frequency modulation frequency transmitting module transmits signals to the two clock towers at the same time, the clock towers do not need to tell time according to own time telling systems at the moment, the two clock towers receive the same signals at the same time and tell time, and the situations that time telling sounds are not synchronous and echoes exist are avoided.
Description
technical field [0001] The invention belongs to the technical field of clock towers, in particular to a wireless frequency modulation tower clock timekeeping control system. Background technique [0002] The clock tower has a long history and appeared in the Middle Ages. It was used to measure time and is also the wisdom of medieval craftsmen. In modern clock towers, it has generally been used as a tourist attraction, and some famous clock towers have been listed as cultural heritage. [0003] Two tower clocks with timekeeping function are installed at a distance of more than 300 meters. The conventional method is to install two sets of timekeeping systems. Usually, the two systems will produce timekeeping sounds that are out of sync and have echoes. To solve this problem, a timekeeping system was invented to transmit audio wirelessly. . Contents of the invention [0004] The object of the present invention is to propose a wireless FM tower clock timekeeping control syste...
