Description

一种基于机顶盒的气象信息采集方法及其系统  Meteorological information collecting method and system based on set top box
技术领域 Technical field
本发明涉及机顶盒技术领域，特别涉及一种基于机顶盒的气象信息采集方法及其系统。 The invention relates to the technical field of a set top box, in particular to a method and system for collecting weather information based on a set top box.
背景技术 Background technique
现有的气象信息采集主要依靠各地的气象部门（在当地的几个地方设立气象站）监测气象信息数据，或通过气象卫星采集大气卫星云图数据；再经过气象数据平台对这些数据进行加工处理，就可以用来预测未来一段时间的气象变化。气象台定时通过广播、网络、媒体等途径向社会发布天气预报信息或气象灾害预警，在工农业生产、军事、航海航空、救援等活动中发挥越来越重要的作用。 The existing meteorological information collection mainly relies on the meteorological departments of various places (establishing weather stations in several local areas) to monitor meteorological information data, or collect atmospheric satellite cloud image data through meteorological satellites; and then process these data through meteorological data platforms. It can be used to predict meteorological changes over time. The Meteorological Observatory regularly issues weather forecast information or meteorological disaster warnings to the public through broadcasting, internet, media, etc., and plays an increasingly important role in industrial and agricultural production, military, maritime aviation, and rescue activities.
目前，随着音视频压缩编解码技术的日益发展与成熟，使用各种信道传输的机顶盒或解码终端进入千家万户。机顶盒或解码终端的普及，广电网络或其他信道传输基础设施的成熟和完善，不仅极大地丰富了用户的精神文化生活，同时也为各类信息资源的融合和推送提供了一个广阔的途径。有线机顶盒采用完善的有线电视网络，地面机顶盒通过地面数字信号发射基站，卫星机顶盒依靠卫星转发器， IPTV 机顶盒（通过互联网支持 IP 协议的机顶盒） /OTT 机顶盒（互联网电视机顶盒）通过成熟的广域网来作为传输信道。 At present, with the development and maturity of audio and video compression codec technology, set-top boxes or decoding terminals using various channel transmissions enter thousands of households. The popularity of set-top boxes or decoding terminals, the maturity and perfection of radio and television networks or other channel transmission infrastructures not only greatly enrich the spiritual and cultural life of users, but also provide a broad way for the integration and push of various information resources. The cable set-top box adopts a complete cable TV network, the ground set-top box transmits the base station through the terrestrial digital signal, and the satellite set-top box relies on the satellite transponder. IPTV set-top box (set-top box that supports IP protocol via the Internet) / OTT set-top box (Internet TV set-top box) is used as a transmission channel through a mature WAN.
现有的顶盒用通常用来收看各类广播电视节目和网络电视节目，为用户提供各种数据服务。但是，各类机顶盒或解码终端均没有在气象信息采集、给气象数据平台提供信息资源方面发挥作用。气象信息采集总体偏向大范围的全局性，数据样本规模应对日益精细准确的气象信息需求还是不够大。另外，现阶段的气象信息发布平还是趋向定时更新，定时发布；这对于实时性要求比较高的场合，不能对突发的恶劣天气起到及时警示作用（如长江'东方之星'沉船事件）。 The existing top box is generally used to watch various types of broadcast television programs and network television programs, and provides various data services for users. However, all types of set-top boxes or decoding terminals do not play a role in collecting meteorological information and providing information resources to the meteorological data platform. The overall collection of meteorological information is biased towards a large-scale overall situation, and the size of the data sample should not be sufficient for the increasingly precise and accurate meteorological information needs. In addition, the current level of meteorological information release tends to be regularly updated and scheduled for release; this is not a timely warning for sudden bad weather (such as the Yangtze River 'Oriental Star' shipwreck event) for occasions with high real-time requirements. .
因而现有技术还有待改进和提高。 Therefore, the prior art has yet to be improved and improved.

具体实施方式 detailed description
本发明提供一种基于机顶盒的气象信息采集方法及其系统。通过气象采集装置在用户的所在地采集该地方的小范围的气象数据，由机顶盒接收打包后通过传输信道传输给气象台。气象台对各个用户所在地的气象数据进行分析和处理。这些数据一方面作为卫星云图数据和气象部门观测站采集数据的补充，以扩充数据样本，从而能对局部未来一段时间的天气变化作出更准确的预计；反馈至机顶盒中方便用户查看实时天气预报。另一方面，使用更多样本的气象数据，能更准确地监测和跟踪异常突变天气，实时反馈给机顶盒进行不定时的突发预警，可提高气象信息发布的实时性。 The invention provides a meteorological information collection method based on a set top box and a system thereof. A small range of meteorological data of the place is collected by the meteorological acquisition device at the location of the user, and is received by the set top box and transmitted to the weather station through the transmission channel. The meteorological station analyzes and processes the meteorological data of each user's location. These data, on the one hand, complement the data collected by the satellite cloud image data and meteorological observatories to expand the data samples, so as to make more accurate predictions of local weather changes for a certain period of time; feedback to the set-top box allows users to view real-time weather forecasts. On the other hand, using more samples of meteorological data, it is possible to more accurately monitor and track abnormal abrupt weather, and feedback to the set-top box in real time for unscheduled emergency warning, which can improve the real-time release of meteorological information.
为使本发明的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本发明进一步详细说明。 应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。 The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
请参阅图 1 ，本发明提供的基于机顶盒的气象信息采集方法由气象采集装置、机顶盒、气象台实现，其主要分为气象信息的采集和播放，具体包括： Please refer to Figure 1 The meteorological information collection method based on the set top box provided by the present invention is implemented by a meteorological acquisition device, a set top box, and a meteorological station, and is mainly divided into the collection and playback of meteorological information, and specifically includes:
S100 、气象采集装置采集气象数据并传输给机顶盒； S100, the meteorological acquisition device collects the meteorological data and transmits it to the set top box;
S200 、机顶盒对气象数据打包后通过传输信道发送至气象台； The S200 and the set top box package the weather data and send it to the weather station through the transmission channel;
S300 、机顶盒接收气象台反馈的天气预测信息，解析后传输给电视机。 The S300 and the set-top box receive the weather forecast information fed back by the weather station, and then analyze and transmit the weather forecast information to the television.
在所述步骤 S100 中，气象采集装置是实时地采集气象数据，但机顶盒不会持续开机。则在气象采集装置传输气象数据给机顶盒之前，所述气象采集装置会先判断机顶盒的开关机状态。如检测机顶盒内的待机信号输入管脚上的电平变化情况，平时该待机信号输入管脚为高电平，当开关机按键被按下时变为低电平，检测到由高电平变为低电平则识别为进行了一次开机或关机操作。机顶盒会主动向气象采集装置读取气象数据，若是开机操作，则气象采集装置检测到电平变化后还会接收到读取指令，即判断机顶盒开机。若是关机操作，则机顶盒与气象采集装置之间无通信，即气象采集装置检测到电平变化但没有接收到任何指令，则判断机顶盒关机。 In the step S100 In the middle, the meteorological acquisition device collects meteorological data in real time, but the set top box does not continue to boot. Then, before the weather collection device transmits the weather data to the set top box, the weather collection device first determines the state of the on/off of the set top box. For example, if the level change on the standby signal input pin in the set top box is detected, the standby signal input pin is normally at a high level, and when the switch is pressed, the level is changed to a low level, and the high level is detected. A low level is recognized as a power on or off operation. The set-top box will actively read the meteorological data to the meteorological acquisition device. If the operation is started, the weather acquisition device will also receive a read command after detecting the level change, that is, the set-top box is turned on. If the operation is off, there is no communication between the set top box and the weather collection device, that is, the weather collection device detects the level change but does not receive any command, and then judges that the set top box is turned off.
若判断机顶盒处于关机状态，则气象采集装置存储所采集的气象数据，并记录存储的起止时间。起始时间是第一次检测到机顶盒关机的时间，停止时间是检测到机顶盒开机的时间。由于是实时采集，所有时间点太多，且这两个时间点的气象数据是作为历史参考数据，只需记录两个时间点就能明确该时间段内的天气变化情况，还能减少数据量。若判断机顶盒处于开机状态，则将存储的气象数据和采集的气象数据传输给机顶盒。 If it is determined that the set top box is in the off state, the weather collection device stores the collected meteorological data and records the stored start and end time. The start time is the first time the set-top box is turned off, and the stop time is the time when the set-top box is turned on. Because it is real-time acquisition, there are too many time points, and the meteorological data of these two time points is used as historical reference data. It only needs to record two time points to clarify the weather changes in the time period and reduce the amount of data. . If it is determined that the set top box is in the power on state, the stored weather data and the collected weather data are transmitted to the set top box.
本实施例中，所述气象采集装置包括用于测风速和风向的风向标，用于检测温度湿度的温湿度传感器，用于检测气压的大气气压计，测量降水量的雨量计，获取位置信息的 GPS 模块，记录气象数据的采集时间（包括日期、北京时间，即该气象数据存储至 MCU 时的具体时间）、存储并传输气象数据的 MCU 。 MCU 通过 USB 接口与机顶盒内的 SOC 芯片（即机顶盒常用的主控制芯片）通讯。 In this embodiment, the meteorological acquisition device includes a wind direction indicator for measuring wind speed and wind direction, a temperature and humidity sensor for detecting temperature and humidity, an atmospheric barometer for detecting air pressure, a rain gauge for measuring precipitation, and acquiring position information. GPS The module records the acquisition time of the meteorological data (including the date, Beijing time, that is, the specific time when the weather data is stored to the MCU), and the MCU that stores and transmits the weather data. MCU via USB The interface communicates with the SOC chip in the set top box (ie, the main control chip commonly used in the set top box).
由于风向标、温湿度传感器、大气气压计、雨量计、 GPS 模块是实时采集相关数据并传输给 MCU 的，数据量太大。为此，在所述步骤 S200 中， MCU 会先暂存气象数据，机顶盒内的 SOC 芯片每隔预设时间向 MCU 发出一次读取指令，即可获取一次气象数据。之后 MCU 清除所获得的气象数据之前的气象数据。这样机顶盒每读取一次，气象采集装置就对历史数据进行清除，之后再继续暂存后续获取的气象数据，即可节省 MCU 的存储空间，减轻数据传输量。 Because the wind vane, temperature and humidity sensor, atmospheric barometer, rain gauge, and GPS module collect relevant data in real time and transmit it to the MCU. The amount of data is too large. Therefore, in the step S200, the MCU temporarily stores the meteorological data, and the SOC chip in the set top box goes to the MCU every preset time. Once the read command is issued, the weather data can be obtained once. After MCU Clear the meteorological data before the obtained meteorological data. In this way, each time the set-top box is read, the weather acquisition device clears the historical data, and then continues to temporarily store the subsequently acquired meteorological data, thereby saving the MCU. Storage space to reduce the amount of data transfer.
需要理解的是，若气象采集装置关机，则不采集气象数据，但关机前存储所采集的气象数据，此时的停止时间是气象采集装置的关机时间。为了避免突然断电导致气象数据来不及保存，可在气象采集装置内设置可充电电池、对应的供电电路和充电电路。断电时，电池电压通过供电电路处理（如滤波、稳压、升降压（根据实际各模块的电压需求进行））后传输给对应的模块供电。上电时市电通过充电电路降压后对可充电电池充电。 It should be understood that if the weather collection device is turned off, the meteorological data is not collected, but the collected meteorological data is stored before the shutdown, and the stop time at this time is the shutdown time of the meteorological acquisition device. In order to avoid the sudden loss of power and the loss of meteorological data, a rechargeable battery, a corresponding power supply circuit and a charging circuit can be arranged in the weather collection device. When the power is off, the battery voltage is processed by the power supply circuit (such as filtering, voltage regulation, and buck-boost (according to the actual voltage requirements of each module)) and then transmitted to the corresponding module for power supply. At the time of power-on, the mains charges the rechargeable battery after being stepped down by the charging circuit.
机顶盒在后台运行对应的进程完成气象数据的读取、打包处理和传输控制。在所述步骤 S200 中，机顶盒将获取的气象数据按序（包括气象数据的采集时间 D0 、风速风向 D1 、温度湿度 D2 、气压 D3 、降水量 D4 、位置信息 D5 ）封装成气象数据包 P ；根据相应的传输信道或途径将气象数据包 P 发送给气象台。 The set-top box runs the corresponding process in the background to complete the reading, packing processing and transmission control of the meteorological data. In the step S200 In the middle, the set top box will obtain the meteorological data in order (including the meteorological data acquisition time D0, wind speed and direction D1, temperature and humidity D2, air pressure D3, precipitation D4, position information D5). Packaged into a weather packet P; the weather packet P is sent to the weather station according to the corresponding transmission channel or path.
由于位置信息通常不变（因机顶盒通常放在固定的地方），当机顶盒位置更改（如搬家）时，气象采集装置的位置也更改。在具体实施时，还可在气象数据包 P 内增加位置信息是否更新的标志位 flag ，如图 2 所示的封装格式。标志位 flag 为 0 ，表示位置没改，气象台可不读取后续的位置信息 D5 ；若标志位 flag 为 1 ，表示位置更改，读取位置信息 D5 。这样可减少不必要的读取工作量。 Since the location information is usually unchanged (because the set-top box is usually placed in a fixed location), the location of the weather collection device changes when the location of the set-top box changes (such as moving). In the specific implementation, it can also be in the weather data package P The flag flag is added to the location flag to update the location information, as shown in Figure 2. The flag flag is 0, indicating that the position has not changed, the weather station may not read the subsequent position information D5; Flag is 1 for position change and position information D5 is read. This reduces unnecessary reading effort.
气象数据包 P 传输到气象台的数据处理服务器的过程，由机顶盒的类型选择对应的传输信道实现。 The process of transmitting the weather data packet P to the data processing server of the weather station is realized by selecting the corresponding transmission channel by the type of the set top box.
若是有线机顶盒，如图 3 所示。利用双向通讯的 Cable Modem ( 电缆调制解调器，以下简称 CM 模块 ) ，将气象数据包 P 调制到 CM 模块的上行信道上，通过双工器（将发射和接收讯号相隔离，保证接收和发射都能同时正常工作）发射至 CMTS （ Cable Modem Terminal Systems ，是管理控制 Cable Modem 的设备）设备解调后，再由 CMTS 设备将数据传输到广域网，最后传输到气象台的数据处理的服务器。气象台反馈天气预测信息给机顶盒时，按照该发送方式的逆方式进行，只是使用 CM 模块的下行信道进行接收。 If it is a cable set-top box, as shown in Figure 3. Cable Modem using two-way communication (Cable Modem, hereinafter referred to as CM Module), the weather data packet P is modulated onto the upstream channel of the CM module, and transmitted to the CMTS through a duplexer (isolated to transmit and receive signals to ensure that both reception and transmission can work normally). Cable Modem Terminal Systems, which is the device that manages the Cable Modem), demodulates the device, and then CMTS The device transmits the data to the WAN and finally to the data processing server of the weather station. When the weather station feeds back the weather forecast information to the set-top box, it is performed in the reverse manner of the sending method, except that the CM is used. The downlink channel of the module is received.
若是地面机顶盒或卫星机顶盒，如图 4 所示。由于这类广播电视的传输信道都是利用在自由空间传播的电磁波，因此不具备数据回传的功能。为了传输气象数据包 P ，这两类机顶盒需要安装短信收发模块（如短信猫）。该短信收发模块内需安装 SIM 卡，该 SIM 卡应支持 TD-SCDMA （ Time Division-Synchronous Code Division Multiple Access ，时分同步码分多址）或 WCDMA （ Wideband Code Division Multiple Access ，宽带码分多址）移动通信协议。短信收发模块将气象数据包 P 转换成短信息的数据格式并按照短信的发送方式发给基站服务器，由基站服务器解析成气象台服务器所能识别的数据格式并发送给气象台服务器。气象台反馈天气预测信息给机顶盒时，按照该发送方式的逆方式进行。 If it is a ground set-top box or a satellite set-top box, as shown in Figure 4. Shown. Since the transmission channels of such broadcast televisions utilize electromagnetic waves propagating in free space, they do not have the function of data backhaul. In order to transmit weather data packets P These two types of set-top boxes need to install SMS transceiver modules (such as SMS cats). A SIM card is required in the SMS transceiver module. The SIM card should support TD-SCDMA (Time). Division-Synchronous Code Division Multiple Access, or WCDMA (Wideband) Code Division Multiple Access, mobile communication protocol. SMS transceiver module will weather data packet P The data format converted into short message is sent to the base station server according to the manner of sending the short message, and the base station server parses the data format that can be recognized by the weather station server and sends it to the weather station server. When the weather station feeds back the weather forecast information to the set top box, it proceeds in the reverse manner of the transmission method.
若是 OTT/IPTV 类的机顶盒。这类机顶盒是通过宽带网络作为传输媒介的，因此只需将气象数据包 P 封装成网络气象数据包既可发送给气象台服务器。同理，气象台反馈天气预测信息给机顶盒时，按照该发送方式的逆方式进行。 If it is a set-top box of OTT/IPTV type. This type of set-top box is used as a transmission medium through a broadband network, so only the weather data package is required. Packaged into a network weather packet can be sent to the weather station server. Similarly, when the weather station feeds back the weather forecast information to the set-top box, it proceeds in the reverse manner of the transmission method.
气象台服务器对获取的气象数据进行分析和处理。一方面，基于所有机顶盒端传输过来的数据，气象台依据沿一定方向位置的气压变化和风速变化，预测和监控局部的天气。另一方面，可以将机顶盒端获取的气象数据作为专业气象监测点或卫星云图数据的辅助分析数据，修正气象部门的预测结果，使分析更趋精准。 The meteorological station server analyzes and processes the acquired meteorological data. On the one hand, based on the data transmitted from all set-top boxes, the weather station predicts and monitors local weather based on changes in air pressure and wind speed at locations along a certain direction. On the other hand, the meteorological data acquired by the set-top box can be used as auxiliary analysis data of professional meteorological monitoring points or satellite cloud image data, and the forecast results of the meteorological department can be corrected to make the analysis more accurate.
气象台服务器获得天气预测信息后反馈给机顶盒。机顶盒将天气预测信息解析成对应的文字，传输至电视机的屏幕下方滚动播放天气预报。这样用户即可随时了解当前的天气预报。若气象台无反馈，则不播放。 The weather station server receives the weather forecast information and feeds it back to the set top box. The set-top box parses the weather prediction information into corresponding text, and transmits it to the lower part of the screen of the television to scroll the weather forecast. This allows users to keep track of current weather forecasts. If there is no feedback from the weather station, it will not play.
由于用户通常仅关心当地的天气，而气象台反馈的天气预测信息设计全国各地，范围较大且数据量也大。基于天气预测信息必定包括地理位置（如在哪个县、哪个市、哪个区），进一步实施例中，所述机顶盒根据位置信息识别所在地理位置，从天气预测信息中查询出匹配的地理位置和天气预测信息，再解析成对应的文字播放。 Since the user usually only cares about the local weather, the weather forecast information fed back by the weather station is designed throughout the country, and the range is large and the amount of data is large. Based on the weather prediction information, the geographic location (such as which county, which city, and which district) must be included. In a further embodiment, the set top box identifies the geographic location based on the location information, and queries the weather forecast information for the matching geographic location and weather. Predict the information and parse it into corresponding text playback.
