摘要
为进一步提高配电终端的运行能力以及快速可靠的故障处理能力,配电终端逐渐由单核处理器发展为多核处理器,由此带来了多核处理器之间数据通信的需求。基于物联网协议MQTT实现了一种新型的多核处理器核间通信技术,将共享内存封装成MQTT交互协议格式,保证各核数据的独立、互斥与共享,从而实现多核处理器各内核间简易可靠的数据通信方式。在此基础上采用MYC-C7Z015芯片进行配电终端硬件设计,并研究MYC-C7Z015芯片核间的数据通信方式,提升了配电终端的数据容量及运行能力。通过核间通信时延测试、通信极限测试,配电终端功能测试,验证了基于MQTT的配电终端核间通信的性能,简化了核间应用层通信代码设计,提升了配电终端性能。
In order to improve the capabilities of operation and fault handling of the power distribution terminal, the terminal has been upgraded from single-core processor to multi-core processor gradually, which brings about the demand for data communication between multi-core processors. Based on the protocol of MQTT,a flexible and simple technology on the inter-core data communication of multi-core processors is introduced and designed. On this basis, the power distribution terminal with inter-core data communication in the MYC-C7 Z015 chip is realized. Through inter-core communication delay test, communication limit test, and power distribution terminal function test, the performance of the MQTT-based inter-core communication is verified, the application layer inter-core communication code design is simplified, and the performance of power distribution terminal is improved.
