基于电力线收发器的KJ328煤矿安全监控系统

KJ328 coal mine safety monitoring and control system based on electric power line transceiver

为了改善煤矿安全监控系统的抗电磁干扰能力,研发一种新的KJ328煤矿安全监控系统,详细介绍了KJ328煤矿安全监控系统的结构、技术性能和特点。该系统采用基于PL3150或者PL3120的具有超强抗电磁干扰能力的通信收发器。该收发器使用了窄带技术,多数据位相关器、脉冲噪声抑制、畸变纠正等专利算法,前向纠错、双载波频率等多种手段,提高通信的抗电磁干扰能力。电磁兼容性抗扰度试验表明,该系统具有超强抗电磁干扰能力。

In order to improve the anti-electric magnetic interference ability of the mine safety monitoring and control system,a new KJ328 coal mine safety monitoring and control system was developed.The paper in detail introduced the structure,technical performances and features of the KJ328 coal mine safety monitoring and control system.The system was equipped with a communication transceiver with a super power anti-electric magnetic interference ability based on the PL3150 or PL3120.The transceiver with a narrow b...
