In this embodiment, the server is a Web server, and the display module is in communication connection with the Web server. The display module is a browser, communicates with the Web server through the browser, and displays data on the Web server on a webpage on the browser.
Considering that the detection range of a single radar is limited, and even in an effective detection range, many regions cannot be detected by the radar, such as a region below the lowest elevation angle of the radar, a cone region, a region between two adjacent 2 elevation angles, a ground line obstruction, and the like; therefore, in the embodiment, when the meteorological information is acquired, the cloud measuring radar, the rain measuring radar and the wind measuring radar are respectively multiple, the data of the radar in the local area is not processed, and the data of the radar in the peripheral area is combined, so that the detection blind area of the radar is reduced, and the data is more real.
Of course, the database on the server may also be a database server for storing data, and the database server is at least provided with three mapping relationship tables of weather information corresponding to the next time period and predicted by different weather information acquired by the cloud radar, the rain radar and the wind radar and the next time period. In this embodiment, the number of the mapping relationship tables is three, and the mapping relationship tables are respectively mapping relationship tables of weather information corresponding to a next time period and predicted by different weather information acquired by the cloud radar, the rain radar and the wind radar, and the mapping relationship tables are corresponding to the next time period.

The data analysis of the cloud and wind lidar may also include a number of parameters, such as: after the anemometry radar data are analyzed, the wind speed and the wind direction exist, so that at least three mapping relation tables exist.
In order to enable a user to better browse the meteorological information of each divided area, the system further comprises a terminal, and the terminal is in communication connection with the Web server. When the map information display device is used, a user calls data on the Web server through the terminal, the Web server calls the geographic information in the map server and the mapping relation table in the database to be overlapped together according to the user requirement and returns to the user terminal, and the geographic information and the mapping relation table are displayed through images. Therefore, the user can more visually acquire the meteorological data of the divided areas on the map through the meteorological display system, and the meteorological display system acquires the data of the three radars and can correspondingly acquire cloud layer information, precipitation information, wind speed information and the like respectively, so that the user can check different meteorological information according to various requirements.

Of course, the comparator may be single or multiple, and may respectively compare parameter data in each different weather information to obtain a disaster early warning signal that may be caused by a single weather information, or may comprehensively analyze multiple weather information to obtain a disaster early warning signal that may be comprehensively caused. For example: the typhoon early warning signal is obtained by carrying out comprehensive analysis according to a wind measuring radar and a rain measuring radar, and the typhoon early warning signal can be generated only when two conditions that the predicted wind speed exceeds a wind speed set value and the predicted precipitation exceeds a precipitation set value are met; when the predicted wind speed exceeds the set wind speed value and the predicted precipitation exceeds the set precipitation value, only one condition is met, a strong wind early warning signal or a rainstorm early warning signal is sent out, and a typhoon early warning signal is not sent out.
In this embodiment, the disaster early warning signal includes debris flow, mountain torrents, urban waterlogging, and typhoon early warning signal at sea in the mountain area. For example: when the rainfall amount of a certain mountain area is larger than the set value in the comparator, debris flow and torrential flood are easily caused, so that disaster early warning signals of the debris flow and the torrential flood can be generated; if the wind speed of a certain sea area is larger than the set value of the wind speed in the comparator, typhoon is easy to appear, and the system can generate a marine typhoon early warning signal and send the marine typhoon early warning signal to the server; of course, there are other disasters expected to occur that are comprehensively evaluated based on the map information and the weather information.
