什么是空调切换器
什么是空调切换器，它的应用功能特点概述。
空调切换器（空调定时切换空调故障切换空调运行故障报警）是一种通用型智能空调控制器，能监测2-3台空调机的运行状态，按照预先设置好的程序控制空调的运行和停机。
适用于市面各种品牌柜式、分体壁挂、吸顶式空调机，有/无遥控器均可，安装方式有所不同。
产品特点。
1、在线检测：实时监视参与控制的空调机的运行状态，面板指示灯标示其运行/故障状态。
2、定时切换：两台/三台空调机根据预先设置好的切换周期轮流运行，切换周期：2、3、8、12、24、48 、168小时；3、温控切换：根据室内温度确定投入运行的空调机台数。
4、组合模式（温控+定时）切换：温度优先，在满足设定温度条件下，定时切换。
5、故障切换：当某台空调机在运行过程中出现故障时，该空调自动退出循环，控制器在30秒内自动启动其它待机状态的空调，并输出报警。
6、维护设置功能：可随时选择某台空调参与或不参与切换，此功能可保持某台空调常开或常关，而不影响切换功能。
7、具有断电来电或异常停机自启动功能：当空调机出现故障或停电时，空调机停机；故障消除或重新来电后，控制空调机按设定的规则重新启动，不需要人工干预。
8、可与动力环境监控系统联网，空调切换失败，某台空调开启或关闭不成功，输出报警信号。
（可选配我公司其它报警设备）9、安装简便：通过识别空调遥控器红外开关机信号即可。
不需要拆卸、改动空调即可完成安装。
空调切换器主要功能1、监视空调机的运行状态:ZHT-ACO3D控制器能监视2/3台空调机的运行状态，并在面板上用指示灯指示其工作状态。
空调开机原则：先开后关（即，先打开应该开的空调，然后再关闭应该关的空调，确保切换安全），如果发现有开启不成功的空调，则强制开启其它所有能投入运行的空调，并报警（可选声光报警和电话拨号报警）。
2、定时切换模式：2/3台空调机根据预先设置好的切换周期轮流运行。
2、4、8。
、12、24、48、168小时三台的定时切换逻辑：默认开启2台，每台按设定的时间轮流休息。

大金空调监控协议转换器
大金空调监控协议转换器专利说明书发明人穆丹枫技术领域本实用新型提供了一种通用的RS485接口，支持MODBUS-RTU协议，可以方便的实现在大金空调的远程监控和两台空调之间实现轮流工作，适用于实现以下功能：1 通过MODBUS协议读取大金空调的运行状态，实现远程控制。
2 机房空调的时间轮值（双机切换）。
3 读取大金空调的故障状况，实现故障报警背景技术日本大金空调采用高效耐用的优质压缩机和稳定易控的电路系统，十分适合机房使用，大金空调提供了P端子应用于外接监控系统，可以多台空调联网运行，统一调度。
机房空调运行条件苛刻，24小时运转使压缩机温度会不断攀升，遇到外机过脏或电压偏低等情况都会造成系统故障，为解决此问题，让两台空调轮流工作是合适的解决办法，一方面大大降低了故障几率，另一方面，在一台机出现故障的情况下可及时转换到另一台运行，特别适应于无人值守的情况。
因大金空调采用日本独有的数据通信传输协议Homebus，和国内常见的RS485传输协议并不兼容，限制了大金空调在远程监控和智能控制方面的应用。
为解决此问题，我设计这款智能控制器，利用两条无极性的数据线从大金空调P端子将空调运行数据采集，传输到主板进行数据转换和执行，转换后的协议采用RS485信号传输，供上位机进行二次开发和监控。
发明内容本实用新型所要解决的技术问题是，利用两条无极性的数据线从大金空调P 端子将空调运行数据采集，转换为RS485接口输出，转换后的通信协议为MODBUS-RTU.本实用新型是这样的，先利用HBS解码电路对空调发出的HBS信号进行解码，用单片机的程序对编码进行分析，然后将空调机的开关和温度代码写入存储器进行记忆；控制器外接485驱动电路，经CPU运算后，向外输出MODBUS协议格式的RS485信号。
本设备还配有热敏电阻，不停对环境温度进行判断，并显示在数码管上。
控制器有按纽输入设定温度和切换时间，当控制器工作时，中央控制器CPU对通信传输的信号进行综合判断，发出控制空调开关机等指令，系统也会把空调的运行状况和故障情况实时传递到485端口，供上位机查询。

unit.Recommended maintenance intervals may vary depending on the installation environment,e.g.,dusty zones,etc.Refer to Table 1.Cleaning the CoilClean the coil at the beginning of each cooling season,or when e a vacuum cleaner or a long-bristle brush to avoid damage to the coil fins.Air FiltersRemove and clean the air filters once a month.NOTE:If air filters show signs of excessive wear or are torn,they must be replaced.Contact your local dealer for replacement filters.1.Open front panel on unit.2.Pull filters down to remove.3.Vacuum filters.4.Clean with warm water.5.Shake filter to remove excess water and dry thoroughly.6.Replace filter by sliding into rack until filter snaps in place.7.Close front panel on unit.Indoor Unit Front PanelTo clean the front panel on the indoor unit,wipe the outside with a soft,dry cloth.If necessary,a mild liquid detergent can be applied and wiped off with a dry cloth.Preparing for Extended Shutdown PeriodClean the filters and reposition them in the unit.Operate the unit in Fan only mode for 12hours to dry all internal parts.Turn main power supply off and remove batteries from the remote control.System Operation RecommendationsThe items outlined in the following list helps to assure proper system operation:S Replace both remote control batteries at the same time.S Point the remote control toward the unit display panel when transmitting a command.S Keep doors and windows closed while unit is operating.S Contact an authorized service representative if a problem arises that cannot be easily resolved.S Do not perform cleaning or maintenance activities while unit is on.S Keep display panel on unit away from direct sunlight and heat as this may interfere with remote control transmissions.S Do not block air intakes and outlets on the indoor or outdoor units.Energy Saving RecommendationsThe following recommendations add greater efficiency to the ductfree system:S Select a comfortable thermostat setting and leave it at chosen setting.Avoid continually raising and lowering the setting.S Keep unit filter clean.Frequent cleaning may be necessary depending on indoor air quality.S Use drapes,curtains or shades to keep direct sunlight from heating room on very hot days.S Do not obstruct air intake on front panel.S Turn on air conditioning before indoor air becomes too uncomfortable.TroubleshootingRefer to Table

2、门口机主内存号码设置方法：门口机连第一个切换器（即标有011A的板）的第一路（即011A）的号码为0111-0119这9个中的一个，如这一路有多个门口机串联，则每个门口机各用一个号码；门口机连接第一个切换器的第二路号码为0121-0129这9个中的一个，如这一路有多个门口机，则每个门口机各用一个号码。
余此类推。
（注：这种方法每一路连接门口机数量最多为9个，如要连接更多门口机，则要事先说明）
3、切换器单路接10台以上门口机的内存设置：01AA、02AA。
4切换器接线说明：切换器接管理中心机的是OUTPUT，INPUT 接下一个切换器的OUTPUT，接门口机的是1、2、3、4共4路（路数视切换器的路数而定）。
切换器上接线座上的标号ASGVd与管理机的ASGV对应，与门口机的A1S1GV1对应。

★低温关机省电
★空调来电自启动
★高温报警输出
★远程电脑监控（选配）
★免学习轻松装
几度空调切换器掌握核心科技
拥有完全知识产权
DAS2技术说明
一、双机切换能解决什么问题？
随着网络时代的到来，数据的保管和流动越来越重要，而保管数据的服务器需要24小时稳定工作，对温度的要求十分严格，所以机房空调需要24小时不停运行，而如果一台空调长时间运行，外机发热严重，经常造成压机过热保护或烧毁，从而导致机房温度升高，引发严重问题。
为解决此问题，需要在数据机房安装两台空调，定时切换两台空调的运行和休息，并在故障发生时自动开启另一台空调。
二、双机切换器VS人工切换
比较项目DAS双机切换人工切换
切换时间4小时-48小时1周-1月
均匀性时间精确，分配均匀受人为因素影响
投入成本一次投入，使用十年人力成本不断上升
即时性机房高温时可即时切
换人工到达机房往往需要几个钟
三、几度空调切换器DAS2自动控制原理说明
DAS2是广州几度科技公司的专利产品，专利号ZL20092002502.0,该专利解决了以下两个问题：
1 各品牌不通用：不同空调品牌的空调遥控代码不通用，电路板通信代码不一致，当更换一个不同品牌时，以往的切换器就不能用了。
2 安装麻烦：旧式切换器一般采用连线安装，需要拆开空调进行插接，需要专业的空调技师，安装时间长。
DAS2内置了市面上主流品牌的控制代码，两个控制器可以分别发出不同的控制代码，使得不同品牌的空调可以进行切换。
对于新型
空调，DAS2集成了学习功能，可以在一瞬间学会控制代码。
DAS2的遥控方式，适合主流的空调品牌，通用格力、美的、海尔、大金、三菱海尔、志高、奥克斯、松下、日立等各大品牌，安装时只需要将A、B发射器各对准一台空调，通电即可工作。
真正做到即插即用。
DAS2在工作时，通电进行初始化，常温时会向A机发射开机信号，B机发射关机信号，到了切换时间（默认4小时）后再向B机发射开机信号，向A机发射关机信号，然后依次轮换，从而实现定时切换。
DAS2工作时，每10秒检测一次机房温度，当发现机房温度超出设定的告警温度时，DAS2会进行故障处理，认为当前运行的空调出现故障。
设备第三个输出口的继电器闭合，向外输出告警信号，同时DAS2会打开备用空调，关掉当前运行的空调。
然后进行10分钟温度测试。
10分钟内温度下降，低于告警温度。
设备第三口停止告警，空调维持当前的运行方式继续工作。
10分钟后，温度仍然高于告警温度，则DAS2认为环境温度过高而非空调故障，此时会启动高温双机同开程序，设备会把先前关闭的空调重新打开，一起运转。
双机同开期间，如果温度下降达到设定温度，则转为单机运行，进行定时切换。
双机同关程序为那些需要在冬天省电的机房而设计，在寒冷地区
机房温度已经低于最低温度（比如16度），空调机可以同时关闭，待温度上升到设定温度（比如24度）时，空调会自动打开，进入常温运行状态。
双机切换并不能避免空调故障的发生，它只是通过均匀的运转保证压缩机良好润滑，从而降低故障的发生。
同时，在故障发生时，它会进行紧急处理，将机房的温度恢复到正常的状态。
DAS2可靠性说明
一、产品可靠性的质量保证措施：采用优质的硬件和稳定的软件
二、切换器故障对空调的影响：
万一出现切换器故障，切换器停止工作，造成的后果是空调停止切换，其中当前运行的空调一直运转，关闭的空调一直关闭，直到人工干预。
因为切换器和空调在物理上是隔离的，
切换器的故障并不会传导到空调上，机房温度不会受到影响。
切换器本身的故障可以通过远程监控系统而发现，在没有远程监
控的情况下，需要通过人工巡检的方法来检查。
三、切换器的第三口是通信和故障报警接口，内置报警继电器一个，常开设计，当因为空调故障产生高温告警时，此继电器闭合，向外输出告警信号，此告警信号可以连接声光报警器或连接GSM报警模块，向指定维护人员发消息或电话。
当机房断电时也可以通过GSM模块向指定人员报警。
当来电后，DAS2会自动重启空调，无须人工干预。
通过DAS2实现远程监控
DAS2预留远程接口，增加通信模块即可提供远程监控功能，设备的第三接口（即485接口）可外接485通信设备，与电脑监控主机进行通信，根据传输设备的不同，可以用以下三种方式进行远程监控：
一、本地电脑监控：
通过USB/485转换器，将485信号转换为USB信号，插入电脑USB接口进行通信。
此种通信方式最大传输距离为1000米。
二、无线远程监控：
如果机房无网络接口，可通过插手机卡的DTU设备，将485信号转为GPRS信号，通过移动互联网进行远程传输。
三、关于监控软件：
几度科技专门为控制器开发了控制系统，也可以根据客户的通信协议更改控制器产品的程序，更好的满足客户的需要。
