本发明属于移动通讯领域，尤其涉及一种设备状态信息获取系统及通信方法。The invention belongs to the field of mobile communication, and in particular relates to a device state information acquisition system and a communication method.
背景技术Background technique
设备状态信息表明了设备工作正常与否，对于不同的设备有不同的运行状态指示，为了获取设备运行状态信息，工作人员需要靠近各个设备，通过信息获取装置取得设备的运行状态信息，但对于分布式设备，由于各个设备处于不同的位置，工作人员需要分别靠近这些设备来获取运行状态信息，显然这样比较浪费人力成本，而且还无法及时获取到设备运行状态信息，若设备出现故障，就不能及时处理故障问题。The equipment status information indicates whether the equipment is working normally or not. Different equipment has different operation status indications. In order to obtain the equipment operation status information, the staff needs to get close to each equipment and obtain the equipment operation status information through the information acquisition device. However, for distributed Since each device is in a different location, the staff need to get close to these devices to obtain the operation status information. Obviously, this is a waste of labor costs, and it is impossible to obtain the operation status information of the equipment in time. If the equipment fails, it cannot be timely. Handle failure issues.
特别是对于室内分布系统，它可以很好的改善室内信号强度和解决室内话务量拥塞和干扰问题，在3G网络建设和优化中得到了广泛的应用。Especially for indoor distribution systems, it can improve indoor signal strength and solve indoor traffic congestion and interference problems, and has been widely used in 3G network construction and optimization.
在室内分布系统中，需要使用馈线把模拟信号送到天线和从天线端接收信号。通常室内分布系统包括天线、干线放大器、合路器、分路器等设备，这些装置只能通过指定频段的射频信号，室内分布系统的天线放置在各个楼层的各房间，一般采用吸顶式天线，合路器通常包括一个干路接口和多个支路接口，支路接口的信号可以通过合路器汇聚到干路接口输出，干路接口的信号也可以发送到各个支路接口。通常室内分布系统中干路放大器、天线等设备内置有检测模块和无线通讯模块(包括射频收发模块或蓝牙模块等)，检修人员需要定期到这些设备附近以无线方式收集这些设备的相关信息，但是通常这些设备安装位置分散，且多安装在不易直接检测的地方，比如写字楼、政府机关等位置，这些地方不方便进入，而且由于位置分散，因此采集这些设备的相关信息需要耗费大量时间，成本较高。此外，因为检修人员是定期收集设备信息，所以不能实时查看各个设备的工作状态，当设备出现故障时，也无法在第一时间快速准确地定位到故障设备位置，由于不能及时发现并处理这些问题，业务中断时间长，设备维护成本高。因此，能够准确及时获取到设备的运行状态信息就显得尤为重要。In the indoor distribution system, it is necessary to use the feeder to send the analog signal to the antenna and receive the signal from the antenna. Usually, the indoor distribution system includes antennas, trunk amplifiers, combiners, splitters and other equipment. These devices can only pass through radio frequency signals of specified frequency bands. The antennas of the indoor distribution system are placed in each room on each floor, and ceiling-mounted antennas are generally used. , the combiner usually includes a trunk interface and multiple branch interfaces, the signals of the branch interfaces can be aggregated to the output of the trunk interface through the combiner, and the signals of the trunk interface can also be sent to each branch interface. Usually, in the indoor distribution system, the trunk amplifier, antenna and other equipment have built-in detection modules and wireless communication modules (including radio frequency transceiver modules or Bluetooth modules, etc.), maintenance personnel need to regularly go to the vicinity of these equipment to collect relevant information of these equipment wirelessly, but Usually, these devices are installed in scattered locations, and are mostly installed in places that are not easy to detect directly, such as office buildings and government agencies. These places are inconvenient to enter, and because of the scattered locations, it takes a lot of time to collect relevant information about these devices, and the cost is relatively high. high. In addition, because the maintenance personnel regularly collect equipment information, they cannot check the working status of each equipment in real time. When the equipment fails, they cannot quickly and accurately locate the location of the faulty equipment at the first time. Since these problems cannot be discovered and dealt with in time , the service interruption time is long, and the equipment maintenance cost is high. Therefore, it is particularly important to be able to accurately and timely obtain the operating status information of the equipment.
