Description

信号传输方法，系统，装置，存储介质和电子装置 技术领域
本发明涉及电力载波通信领域，具体而言，涉及一种信号传输方法，系统，装置，存储介质和电子装置。
背景技术
相关技术中空调机组所采用的通信网络，是由通讯线连接内外机组成的。空调无处不在，大量空调的使用也伴随着大量通讯线材的使用。尤其在多联空调机组系统中，具有空调数量多、安装位置或分散或隐蔽等特点，因此，导致现有的多联空调机组通信网络，存在着工程安装成本高和难度高、通讯线接触不良故障难于排查等缺陷。由于供电电力线网络已普遍存在，因此，通过机组供电电源线接入供电电力线网络，可省去通讯线和其工程安装，消除了通讯接触不良的现象。而现有的电力线载波通讯技术都是采用双线差分传输，如果需要通讯的空调接了不同相序的线(如：内机为L1、N，外机为L2、N)，则会造成通讯失败。
针对上述的问题，目前尚未提出有效的解决方案。

通过上述步骤，采用空调机组内的所有机组单元共用多相电力线中的一条电力线，并且使用共用的该电力线进行信号传输的方式，即通过单条电力线建立空调机组内的通信，因而使得所有机组单元无需连接完全相同的相线，就可以实现正常通信，从而降低了对电力线拓扑结构的要求，进而解决了相关技术中电力线载波通信中空调的机组单元之间使用不同相线而导致通信失败的技术问题。

需要说明的是，上述空调机组内的机组单元可以包括：主板控制器，其中，该主板控制器包括：空调控制模块和电力线载波通信模块，空调控制模块和电力线载波通信模块之间通过串口通信。因而，上述步骤S104可以表现为：机组单元中的空调控制模块将需要发送的数据(待传输的数据)通过串口发送给该机组单元中的电力线载波通信模块，该机组单元中的电力线载波通信模块对接收的数据进行处理(优化编码、调制)，使得处理后的数据更适合单线传输，该机组单元中的电力线载波通信模块将处 理后的数据耦合到指定电力线(通讯线)上，其他机组单元中的电力线载波通信模块通过该指定电力线接收到上述数据，然后进行相应的处理(解调，解码)，将解码后的数据通过串口传给该其他机组单元中的空调控制模块。
需要说明的是，为了保证通讯的可靠性，首先，应该使用可纠错编码、并采用适合该信道(通信线)的调制方法，其次，在应用层也应采取相应的校验措施。在环境噪声比较大时，可以选择通过提升发射功率提升信噪比；或者在保证通讯最低速率要求的情况下，降低通讯速率，提升信噪比；也可以两者一同使用，增加通讯的可靠性。

为了更好的理解本发明，以下结合优选的实施例对本发明做进一步解释。
本发明优选实施例提供了一种通过单电力线载波来建立空调机组间通讯的方法，火线、零线、地线都可以作为通讯线。
如图2所示，采用单线PLC通讯的空调机组，室内机和室外机在连接供电网络时无需连接同一相线(L1、L2、L3)即可正常通讯。图2中将零线作为通讯线，实际应用中包括但不限于使用零线进行通讯。
图4是根据本发明优选实施例提供的基于单线传输的电力线通讯的空调机组的通 讯控制结构图，如图4所示，空调机组空调控制器实现将要发送的数据耦合至供电电力线网络及从供电电力线网络解析通讯数据，是由空调机组空调控制模块和电力线载波通讯模块相互协作而完成的，其中空调控制模块与电力线载波通讯模块经由串口通讯进行相互之间的数据交互。
本发明优选实施例基于单线传输的电力线载波通讯(PLC)技术在空调机组通信网络上的应用。其涉及机制如下：
1)空调机组的通讯线路接线方式
空调机组的通讯网络线路即是电力线，只要保证所有机组有一条线在同一线路上即可。鉴于机组单元都需要接零线，所以推荐通过零线进行信号传输，以达到安装简便的目的。
2)空调机组的通讯方式
空调机组空调控制模块将要发送的数据通过串口发送给电力线载波通讯模块，该电力线载波通讯模块再将数据进行优化编码、调制，让其更适合单线传输信道后耦合到通讯线上，其他设备的电力线载波通讯模块通过通讯线收到数据后，进行解调、解码，再将解码后的数据通过串口传给空调机组空调控制模块处理。
3)在远距离传输时的处理方法
在传输时，单线传输信号衰减较大，距离较远的内机可能收不到，此时收不到外机数据的内机向其周边的内机发送代理请求；有能收到外机数据的内机接收到代理请求后，确认，并在之后的传输中做这台内机的中继。
4)通讯可靠性的保证
首先，应该使用可纠错编码、并采用适合该信道的调制方法，其次在应用层也应采取相应的校验措施。在环境噪声比较大时，可以选择通过提升发射功率提升信噪比；或者在保证通讯最低速率要求的情况下，降低通讯速率，提升信噪比；也可以两者一同使用，增加通讯的可靠性。
本发明优选实施例解决了原有电力线载波通讯(PLC)在空调机组网络上存在相线不同而造成通讯失败的问题，降低了对电力线拓扑结构的要求，简化了安装过程。
本发明优选实施例还实现了以下技术效果：节省通讯线材；安装中，无需关注电力线的相线问题；为电力线通讯(PLC)技术在空调机组通讯中提供新的解决方案，也为通信网络实现无工程安装及接触不良等提供了可实行性。

本发明的实施例还提供了一种电子装置，包括存储器和处理器，该存储器中存储有计算机程序，该处理器被设置为运行计算机程序以执行上述任一项方法实施例中的步骤。
在本发明实施例中，上述电子装置还可以包括传输设备以及输入输出设备，其中，该传输设备和上述处理器连接，该输入输出设备和上述处理器连接。该电子装置可以是上述机组单元，但并不限于此。
