Description

一种空调机组故障诊断方法及系统
本申请要求于2018年9月19日提交中国专利局、申请号为201811095678.7、发明名称为“一种空调机组故障诊断方法及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及空调领域，尤其涉及一种空调机组故障诊断方法及系统。
背景技术
空调机组工作时，控制器会对机组运行条件、运行环境、当前的机组状态进行检测，如果某一时刻机组进入到非正常运行状态，控制器会向上位机反馈故障信息并使空调机组停止工作，此时显示屏会显示主板发来的故障信息，
与此同时，空调机组的无线数据传输模块(内集成有数据流量卡)会将故障信息上传给数据中心，该系统存在以下问题：
无线数据传输模块上传故障信息时，易受网络连接状态限制，存在故障信息不能实时上传的风险；另一方面，无线数据传输模块使用时不仅仅需要上传故障信息还需要上传很多普通的状态信息(例如：温度、压力等)，很多状态信息没有实时上传的必要，故存在流量的浪费；另一方面，由于显示屏的屏幕大小有限，排版受到限制，故相关故障信息和故障解决方案无法显示详尽。
发明内容
本发明的目的是针对上述现有技术存在的受网络连接状态限制故障信息不能及时上传到数据处理中心的缺陷，提出一种空调机组故障诊断系统，其可及时将控制器检测到的故障信息传输到数据处理中心。
本发明实施例中，提供了一种空调机组故障诊断方法，其包括：检测空调机组的状态信息并判断空调机组的状态信息中是否存在异常状态信息，当空调机组的状态信息存在异常状态信息时，将所述异常状态信息通过第一无线数据通信网络实时传输给数据处理中心，将所述异常状态信息之外的正常状态信息通过第二无线数据通信网络传输给数据处理中心。
本发明实施例中，当空调机组的状态信息不存在异常状态信息时，将空调机组的状态信息通过所述第二无线数据通信网络传输给数据处理中心。
本发明实施例中，所述第一无线数据通信网络为NB-IoT通信网络。
本发明实施例中，所述第二无线数据通信网络为运营商移动通信网络。

本发明实施例中，所述空调机组故障诊断系统还包括显示屏，用于显示所 述控制器提供的信息，所述控制器提供的信息包括所述异常状态信息、筛选后的状态信息以及下一步操作的指示信息。
本发明实施例中，当空调机组的状态信息不存在异常状态信息时，所述第二无线数据传输模块将空调机组的状态信息传输给所述数据处理中心。
本发明实施例中，所述第二无线数据传输模块每间隔一段设定的时间上传空调机组的状态信息。
本发明实施例中，所述第一无线数据传输模块为NB-IoT通信模块。
本发明实施例中，所述第二无线数据传输模块为运营商移动通信模块。
本发明实施例中，所述数据处理中心根据空调机组的状态信息给出反馈信息，并通过移动APP发布出去。
与现有技术相比较，本发明的空调机组故障诊断方法及系统，通过两种无线数据通信网络来分别传输异常状态信息和正常状态信息，可以使得异常状态信息能及时的传送到数据处理中心进行处理；另一方面，机组的状态信息间隔一段时间通过第二数据通信模块传送到数据处理中心，数据处理中心也可以监控这些信息，并通过手机APP反馈预警信息，从而减少第二数据通信模块的流量浪费。
