HART modulator-demodulator

一种hart调制解调器

Abstract

本申请公开了一种HART调制解调器,所述HART调制解调器包括供电电路、微处理器、HART调制解调电路和USB接口电路,通过USB接口电路与上位机进行通讯,如此,HART调制解调器通过USB接口与PC机通讯,既能够在现场利用PC机尤其能够利用笔记本电脑对现场的HART智能设备进行检修与维护,而且,该HART调制解调器中添加有抗干扰处理技术的处理流程,因此,提高了HART调制解调器的可靠性,降低了故障率。此外,所述HART调制解调器中的主要芯片的成本较低,因此所述HART调制解调器的成本低。
The application discloses a HART modulator-demodulator. The HART modulator-demodulator comprises a power supply circuit, a microprocessor, an HART modulation-demodulation circuit and a USB interface circuit, and is communicated with an upper computer via the USB interface circuit, so that the HART modulator-demodulator is communicated with a PC via a USB interface, enables the on-site HART intelligent devices to be repaired and maintained by utilizing the PC, in particular a notebook computer. Moreover, a processing flow of an anti-interference processing technology is added in the HART modulator-demodulator, so that the reliability of the HART modulator-demodulator is improved and the failure rate is reduced. In addition, the cost of a main chip of the HART modulator-demodulator is lower, so that the cost of the HART modulator-demodulator is lower.
