摘要
应用无线收发的数据传输模块PTR2000,基于一种小型单片机AT89C51技术,采用抗干扰能力较强的FSK方式对数据进行调制/解调,实现数据的无线通信。其工作频率稳定可靠、外围元件少、功耗极低且便于设计生产,非常适合于便携及手持产品的设计及应用,同时可满足无线管制的要求且无需使用许可证,它是目前低功耗、低成本无线数据传输模块的理想选择。
We can realize the wireless correspondence of data based on AT89C51 technology, with applying wireless receiving and dispatching data transmission module PTR2000, using FSK that has the stronger anti-interference ability to modulate and demodulate, it has steady work frequency, a few peripheral elements, the low power loss, and it is advantageous to design and product, so it's suited to design and apply for cellular and hand product, meanwhile, it can satisfy the request of wireless control and don't use licence. At present, it's ideal choice for wireless data transmission module of low power loss and low cost.
