Features of architectural clocks
Architectural clock is a product that many buildings like to use now. It can not only tell the time but also is a good decoration, which can improve the aesthetics of the building to a large extent. In addition, this product has many other specialty. The following editor will briefly introduce the characteristics of this product to you, I hope it can be helpful to you.
1. Energy saving and environmental protection
A large number of high-precision chip electronic components are used in the circuit composition of this product, which has low functional loss, energy saving and environmental protection. The main MCU integrated ic of each circuit board is designed and manufactured with AVR new chip single-chip microcomputer. Compared with the traditional 51 series single-chip microcomputer design, the integration level, calculation speed and memory space are higher, the system function consumption is extremely low, and the reliability is high.
2. Accurate and effective
Accurate time calibration: use the ZH-GPS6600R decoder independently developed by the Japanese GPS satellite transcoding integrated ic, which has 16 channels for real-time processing and acquisition of data, and outputs full time scale synchronous time code (including date and time signals), and the second pulse is instant Error<73±30Ns.
Accurate master clock: The architectural clock uses a high-precision passive crystal oscillator plus a high-precision variable capacitor, and the synchronization error with the slave clock is <0.1ms, which ensures the accurate travel time of the clock.
Data transmission: use TCP/IP network transmission protocol technology, the characteristics are as follows:
(1) Strong anti-interference ability: it can shield the high magnetic field interference generated by machinery and equipment such as bus stations and airports.
(2) Long-distance transmission: the bus length can reach 9800 meters. (Basic: 1500m)
(3) Large system capacity: divided into 8 output channels, which can drive 700 face clocks in total.
The use of this process can ensure that the building clock reference synchronization time signal and related data information are completely shielded from interference signals in various complex interference environments, ensuring real-time and effective data transmission, thereby ensuring the accuracy of the product.
