Main functions of CJ-3900 tower clock
1. Travel time: full computer control and management, screen display, automatic three-hand operation, second hand running like flowing water, which can bring great benefits to the whole building Dynamic, the seconds hand has an automatic feedback function. The master-child clock system adopts closed-loop control to keep the synchronous operation of the master-child clock and the consistency with Beijing time.
Second, GPS satellite timing: use the computer center to connect with the satellite signal receiving equipment, compare the separated standard time with the master clock time, Proofreading to ensure that the operation of the tower clock is synchronized with the standard time to achieve no accumulated errors.
Three, Timekeeping: Multimedia timekeeping is used, and the timekeeping effect is high-fidelity. There are ①British Big Ben music plus bells (three different tones) ②Dongfanghong music bells (four different tones) ③Dongfanghong music plus language timekeeping ④Bells (eight different sounds) Tone) ⑤China, China, the bright red sun never sets music (a kind) ⑥Into the new era music ⑦Discontinued. A computer is required for multimedia timekeeping. The above seven methods can be selected arbitrarily, and language advertisements can also be added according to user requirements.
Four. Lighting: There are two lighting methods (optional): ①Internal lighting on the disk; ②All pointers and scales are illuminated by LED light-emitting diodes, Long service life, continuous and uninterrupted lighting for more than 100,000 hours; the lighting effect is soft and beautiful, and the lighting interval can be adjusted arbitrarily.
Five, Automatic tracking function: After a power failure, the master clock will automatically memorize within a few months. Professional adjustment. It can also be determined according to the user's requirements to determine the non-stop time for power outages.
Six. Monitoring functions: ①Monitoring and controlling the operation of the mother and son clocks. ②Modify and set the time-keeping mode repertoire ③Real-time processing of the signals sent by the sub-clock system, real-time control of the sub-clock lighting and timekeeping. ④Display the master clock time and adjust the master clock time synchronously. ⑤ Check or reset the lighting interval. ⑥ Display the help information of computer operation at any time.
VII. Fault self-diagnosis function: When a fault occurs in a certain part of the system, the controller automatically diagnoses the fault and transmits the fault phenomenon information Control center, the control center immediately displays the fault location, indicating how the fault will be eliminated. This function can only be realized with a computer.
VIII. Advertising playback function (music library): According to user requirements, multimedia technology is used to play music or advertising slogans, with beautiful sound, which establishes the image of the unit good way. For example, "Today is National Day, I wish everyone a happy holiday", all the staff of X X Bureau wish everyone a happy Spring Festival and all the best", etc. This function can only be realized with a computer.
IX. Sync function of each face clock: When a face clock is out of sync with other face clocks, the control system will automatically detect and adjust it to Synchronize.
