根据本公开的实施例，压缩机100还可以包括无线通信模块215，用于压缩机100与其他外部设备217之间的无线通信。无线通信模块215可以设置在压缩机100的电器盒102中，电器盒102可以安装在壳体101的表面上。无线通信模块215可以在压缩机100的部件例如控制装置200与其他外部设备217之间建立无线通信。
根据本公开的实施例，如图2所示，无线通信模块215可以集成在压缩机100的控制装置200中，例如与压缩机100的其他一些电气部件设置在相同的电路板上，并可以通过电路板上的布线与压缩机100的其他部件电连接。或者，无线通信模块215可以设置在控制装置200外部，并(例如，通过布线)电连接至控制装置200，尽管这在附图中并未示出。
无线通信模块215可以包括无线收/发模块，例如射频(RF)收/发模块。更具体地，无线通信模块215可以包括收/发天线、放大器、滤波器、混频器、本地振荡器(LO)等。无线通信模块215可以根据各种不同的无线通信协议中的至少一种进行工作，并且可以包括符合相应协议的多个分立模块或者符合多个协议的集成模块。例如，无线通信协议可以包括蓝牙、无线保真(WiFi)、窄带物联网(NBIoT)、LoRa、ZigBee等。
除了无线通信模块215之外，控制装置200中还可以设置多个部件模块，这些部件模块均可以电连接到无线通信模块215，用于经由无线通信模块215实现压缩机内部与外部设备217之间的数据传输。各模块与无线通信模块215之间可以传输不同类型的数据，例如，压缩机的运行数据、设定参数、固件数据等。各模块与无线通信模块之间可以存在相应的分立数据传输路径，或者其中的两个或者多个可以共享数据传输路径。这种数据传输路径可以是各种通信线路，例如符合相应通信协议的通信线路如ModBus、CAN等。压缩机100还可以包括协议适配模块(例如，包括在无线通信模块中)，用于将无线通信模块接收到的符合无线通信协议的数据转换为适于在相应数据传输路径上传输的数据，或者将在相应数据传输路径上接收到的数据转换为适于根据无线通信协议发送的数据。
各模块与无线通信模块215之间的数据传输可以是单向或者双向的，并可以通过串行和/或并行的方式来进行。另外，在各模块与无线通信模块215之 间，可以存在存储器或缓存区，用以存储或临时存储数据，例如以便适配各模块与无线通信模块215之间数据传输速率的不同。
另外，无线通信模块215与各模块之间的数据传输路径中可以存在中间部件。更具体地，来自无线通信模块215的数据可以先传输至控制装置200，并由控制装置200转发至相应的模块；来自各模块的数据可以先传输至控制装置200，并由控制装置200转发至无线通信模块215。
无线通信模块215可以结合或集成在控制装置200内。控制装置200可以控制压缩机100的整体操作。例如，控制装置200可以根据预设的控制逻辑和压缩机参数对压缩机100进行控制。于是，控制装置200可以是压缩机中各种数据(例如，运行状态/参数等)的汇聚点，因此将无线通信模块215设置在控制装置200内是有利的。
根据该实施例，通过在压缩机100特别是其控制装置200内结合无线通信模块215，可以在远程操作压缩机100。例如，可以通过远程设备如服务器、计算机、移动终端(如平板电脑、手机等)和/或可穿戴设备等，来读取压缩机100的运行数据，修改压缩机100的设定参数，升级压缩机100的控制器固件等。
在一个实施例中，如图2所示，除了无线通信模块215之外，控制装置200还包括微控制器(MCU)205、压缩机控制单元207、传感器模块203、电源模块201以及数据存储模块208。如上所述，根据实际需要，控制装置200可以去除所示出的部分模块或部件，或者还可以包括更多其他的模块或部件。
数据存储模块208可以包括多个部件单元，这些部件单元可以从在压缩机100中产生数据(例如，运行状态)的工作部件接收数据和/或向压缩机100中需要数据(例如，设定参数)的工作部件发送数据，因此可以视为无线通信模块215与压缩机100中作为数据源/汇的内部部件之间的中转部件。通过这些中转部件，无线通信模块215与压缩机100中作为数据源/汇的内部部件之间建立数据传输。
在一个实施例中，数据存储模块208可以包括压缩机运行数据记录单元209，用于记录压缩机控制单元207所采集的压缩机运行数据，例如，警报信息记录以及传感器故障报警记录等中至少之一。警报信息记录可以包括排气温 度超出正常范围警报记录，电机温度超出正常范围警报记录，吸气压力、排气压力超出正常范围警报记录，供电状态超出正常范围警报记录，压缩机运行状态超出正常范围警报记录等中至少之一。传感器故障报警记录可以包括报警发生的时间和次数等中至少之一。例如，压缩机运行数据记录单元209可以是存储器或者存储器中的特定存储空间。压缩机控制单元207可以(例如按照预定的时间间隔)采集其所控制的压缩机在运行过程中的运行数据(包括各种状态数据)，并可以将所采集的数据记录在压缩机运行数据记录单元209中。例如，压缩机控制单元207可以通过其与压缩机部件之间的通信(例如，状态报告)和/或下述的传感器模块来采集运行数据。根据实施例，在微控制器205的控制下，压缩机运行数据记录单元209可以按照预定的时间间隔或者根据外部设备的请求，经由无线通信模块215将其中记录的运行数据发送到外部设备217。
在一个实施例中，数据存储模块208可以包括固件升级单元211，用于升级压缩机100的控制装置200的固件。当存在固件更新时，外部设备217可以经由无线通信模块215向固件升级单元211发送固件更新，固件升级单元211可以存储接收到的固件更新，并可以存储相应的版本号或者更新时间等信息。当然，固件升级单元211也可以在微控制器205的控制下，例如按照预定的时间间隔主动向外部设备217(例如，维护固件的服务器)查询固件更新，并在存在固件更新的情况下从外部设备217下载此更新。在接收到固件更新时，固件升级单元211可以请求微控制器205更新压缩机100的控制装置200的固件。或者，微控制器205可以按照预定的时间间隔查询固件升级单元211中的固件版本，并在存在更新时主动发起固件更新过程。或者，微控制器205可以根据来自外部设备217的请求，来进行固件更新。
在一个实施例中，数据存储模块208可以包括压缩机参数设定单元213，用于设定压缩机100的参数，例如，排气温度保护的温度设定值、电机温度保护的温度设定值、吸气压力保护的压力设定值、排气压力保护的压力设定值、压缩机喷液阀的控制方式等中至少之一。例如，外部设备217可以经由无线通信模块215向压缩机参数设定单元213发送新的参数设置值，压缩机参数设定单元213可以存储接收到的新参数设置值。在接收到新参数设置值时，压缩机参数设定单元213可以请求微控制器205根据新的参数设置值来重新设置压缩 机100的参数。或者，微控制器205可以根据来自外部设备217的请求，来重新设定参数。另一方面，压缩机参数设定单元213还可以(例如，从微控制器205)获取压缩机100的当前参数设定值，并可以经由无线通信模块215向外部设备217发送所获取的当前参数设定值，以由用户通过外部设备217来判断参数设定值是否恰当以及是否需要重新设定参数值。
微控制器205可以控制压缩机100的控制装置200的整体操作。因此，在微控制器205与控制装置200的各部件之间可以存在电连接，图中仅为方便起见并未示出这种电连接。例如，微控制器205可以是各种微控制器件，例如处理器或微处理器(μP)、单片机(MCU)等。控制装置200还可以包括与微控制器205相关联的存储器，用于存储微控制器205的工作所需的代码和/或数据。在微控制器205与无线通信模块215之间，也可以存在数据传输路径。例如，微控制器205可以经由无线通信模块215接收外部设备217的指令或请求，或者向外部设备217发送指令或请求。外部设备217可以与无线通信模块215进行通信，并因此可以通过微控制器205对数据模块进行控制。
压缩机控制单元207可以在微控制器205的控制下，向压缩机主体中的各种部件例如压缩机构、致动机构等发送控制指令。例如，压缩机控制单元207可以包括针对这些部件的驱动装置。例如，压缩机控制单元207可以控制压缩机内部的电设备，例如控制压缩机的电源开关、压缩机喷液阀开度的增加或减小、压缩机底盘加热带的开关等中至少之一。
传感器模块203可以通过布设在压缩机内部各处的传感器来感测压缩机100的运行数据，例如排气温度、电机温度、吸气压力、排气压力、供电状态、压缩机运行状态等中至少之一。压缩机运行数据记录单元209可以至少部分地通过传感器模块203来获得压缩机100的运行数据。
电源模块201可以向控制装置200中的各模块供电。例如，电源模块201可以从压缩机的供电模块接收电力，并将其转换为适于控制装置200的各模块所需的电力。
根据本公开的实施例，集成了无线通信功能的压缩机能够以无线方式对压缩机进行操作，用户不需要到现场连接通信线路到压缩机上以与压缩机进行有线通信。
根据本公开的实施例，通过无线通信模块的数据传输可以是外部设备与压缩机的物理设备之间进行的底层数据传输，而不是与上层应用设备之间的应用层通信。
以上对本公开的实施例进行了描述。但是，这些实施例仅仅是为了说明的目的，而并非为了限制本公开的范围。尽管在以上分别描述了各实施例，但是这并不意味着各个实施例中的措施不能有利地结合使用。本公开的范围由所附权利要求及其等价物限定。不脱离本公开的范围，本领域技术人员可以做出多种替代和修改，这些替代和修改都应落在本公开的范围之内。
