| 楼宇对讲的常规问题表现 The general problem of the building intercom 不开锁、听不见、无图像、不能通话、不能密码开锁、不能刷卡开锁。 Unlocked, unheard, no image, can not call, can not be unlocked by password, can not be locked by card. 2 Two 楼宇对讲系统维修准备工作 Maintenance preparation for building intercom system 修楼宇对讲跟修其它电器可不一样，必须要了解一些必要的知识。必须要了解的有以下几个方面： It is not the same to repair and repair other electrical appliances. It is necessary to know some necessary knowledge. There are the following aspects to be understood: A、楼宇对讲的生产企业名称、电话及安装时间、安装公司； A, the name of the production enterprise, telephone and installation time, installation company of the building intercom; B、该楼宇对讲系统的接线图、说明书，如有维修档案，也最好一并找到； B, the wiring diagram and instructions of the building intercom system, if there is a maintenance file, should also be found in the same way. 这两个前提条件的作用：了解楼宇对讲的生产企业，是在万不得己的情况下，请教于生产企业的技术员；了解安装公司是为了避免同行之间不必要的误会，不形成恶性竞争或出现人为破坏，了解安装时间是以常规损坏去评估出现的问题;了解接线图、说明书及维修档案，自然就是为了更快，更好的完成维修工作了。 These two prerequisites: to understand the role of building intercom production enterprises, is not million has been the case, ask for the technician of production enterprises; understand the installation company in order to avoid unnecessary misunderstanding between peers, not a vicious competition or vandalism, understand the installation time is to assess the problems the conventional understanding of damage; wiring diagrams, instructions and maintenance records, nature is to faster and better to complete the repair work. 3 Three 检修故障的顺序 Order of troubleshooting 先看电，再看线，最后测试其它功能。 Look at the electricity first, look at the line, and finally test the other functions. 4 Four 楼宇对讲主机的维修(即门口机) The mainframe maintenance of the building (that is, the doorway) 不开锁：除钥匙外的任何开锁方法都不能开锁：先请检测开锁线两端是否接好，再用万能表在电锁端测试，在开锁时，是否有超过300毫安的瞬间电流经过开锁线(有，说明主机及开锁线正常，估计为电锁损坏，请更换电锁测试;如没有，再将万能表在主机开锁端测试，如此时有，则开锁线故障，没有说明主机故障)； Don't lock any lock method key can not unlock the lock: first check line ends are connected, then the universal table test in the end in the lock, unlock, if there is a transient current of over 300 Ma after the lock, and that line (host lock line normal, estimates for the lock is damaged, please replace the lock test; if not, then the universal table test, in the end so when the host lock will unlock, line fault, no fault host); 整个单元住户不能开锁，但可以密码或刷卡开锁：可能是主干线短路或某一楼层平台损坏造成，先检查各主线的接线端口，如接线正常，则从第一层的楼层平台开始依次向上检测楼层平台(检测楼层平台：先断开上层的主干线，测试当层，如正常则不管，如不正常，请更换楼层平台再试，直到测试正常为止(如新装一样调试)，依理类推)； The whole unit households no locks, but can be a password or swipe to unlock: it may be the main trunk line short circuit or a floor platform damage, check the connection port of the main line, such as connection is normal, beginning from the first floor platform layer in order to detect floor platform (detection platform: disconnect the upper floors of the main trunk line the test, when the layer, such as the normal matter, if not normal, please replace the floor platform and try again, until the normal test so far (such as new outfit, Yili) on debugging); 听不见： 任意终端与主机处于工作状态时，主机皆听见：先看主机喇叭线是否接好，喇叭是否长锈损坏，可找一差不多大小的任意喇叭更换测试； It can not be heard: when any terminal and host are in working state, the host can hear: first, let's see whether the speaker line is connected properly, whether the horn is rusty or not, and find a size of any horn to replace it. 不能说： 任意终端与主机处于工作状态时，主机说话终端都听不见：先看主机咪头线是否接好，咪头是否因其它原因损坏，如有机会，找一52DB的咪头更换测试(一般的分机咪头可与主机通用)； Don't say: any terminal and the host is in working state, the host terminal can't hear the talk: look at the host microphone line is connected, the microphone is damaged due to other reasons, such as the chance, find a microphone to replace the 52DB test (extension microphone general and universal host); 无视频： 任意可视终端与主机处于工作状态时，可视终端皆不能显示主机前图像：先检查主机摄像头至主机控制板的接线是否完好，再详看摄像头控制板是否有浸水的现像(有浸水现像，摄像头很可能已损坏)，此时，有条件的，拿监视器来测试，将监视器接到主机的视频线端，正常说明主干视频线故障，不正常说明主机故障，最后将摄像头的视频信号直接接入监视器，正常说明主机控制板故障，不正常说明摄像头故障； No video: any video terminal and the host is in working state, can not display the host video terminal before the image: first check the connection to the host host camera control board is intact, and then a detailed look at the camera control board is soaking is like (with water is like, the camera may have been damaged), at this time, conditional the test will take to monitor, monitor to a host video terminal, video shows normal trunk line fault, not normal that host failure, finally the video signal is directly connected to the monitor camera, shows the normal host control board fault, not the camera shows the normal fault; 5 Five 特殊故障 Special fault 任何分机故障，断电重接一次即解决的，多数为软件或硬件深层故障造成的死机现像，经常发生此类故障的，建议发回生产企业检修，以免带来的长久麻烦； The failure of any extension or power failure is mostly caused by a deep breakdown of software or hardware. Such a failure often occurs. It is recommended that it be sent back to the production enterprise for overhaul. 偶尔不开锁、听不见、无图像、不能通话等，但次数较多，具有间隔性特殊的，估计为分机软件或硬件问题造成的死机，请发回生产企业检修;此类软件故障多是断电后重开就消失故障了。 Occasionally, no locks, no hearing, no images, no calls, etc., but many times, with special spacing, it is estimated that the crashes caused by the software or hardware problems of the extension. Please send them to the production enterprise for maintenance. Most of these software failures are broken after power failure. 6 Six 楼层平台及中间设备的维修 Maintenance of floor platform and intermediate equipment 楼宇对讲系统的楼层保护器、楼层解码器或视频分配放大器等楼层中间设备统称楼层平台。任何楼层平台问题，先检查各线端的线是否接好，电源指示灯是否亮，再断开一次电源的线，通电再试。 Floor protectors, floor decoders or video distribution amplifiers, such as floors, are called floor platforms. Any floor platform problem, first check the line end of the line is connected, power indicator light is bright, and then break a power supply line, try again. 楼层平台必须具备的功能：户户隔离保护、视频处理功能，说具体一点，就是必须具有音频、视频、数据信号及电源的智能分配与隔离保护。 Floor platform must have the function: household isolation protection, video processing functions, specifically, is to intelligent distribution and isolation protection with audio, video and data signals and power supply. 7 Seven 楼宇对讲系统的电源维修 The power maintenance of the building intercom system 楼宇对讲系统的电源是非常重要的配套设备之一，一般分为带电池使用功能和不带电池使用功能两种，考虑到多种原因，在甲方没特殊要求时，不配电池。 The power of building intercom system is one of the most important supporting devices. It is generally divided into two kinds, that is, the function of battery and the function of not using batteries. For a variety of reasons, it is not suitable for batteries when there is no special requirement of Party A. 使用变压器的线性电源，先测量有无220V市电输入变压器，再测量有无电源输到控制板，如有，说明控制板损坏，建议发回生产企业检修； Using the linear power supply of transformer, we first measure whether there is a 220V input transformer, then measure whether there is a power supply to the control panel, if there is, explain the damage of the control panel, and suggest that we send it back to the production enterprise for overhaul. 使用开关电源的，维修难度较高，如测量到有市电输入，但没有输出，建议发回供货商检修;使用三年以上的电源，建议修不如换新。电源输出电流变小、输出电压变低：此类情况多为电源元器件老化，建议更换新电源。 The use of switching power supply is more difficult to maintain. For example, if there is electricity input, but no output, it is recommended to send it back to the supplier for maintenance. If the power is used for more than three years, it is recommended to repair it instead of replacing it. The power output current becomes smaller and the output voltage is lower: this kind of situation is mostly the aging of the power supply components, and it is suggested to replace the new power supply. |
