Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
The first embodiment is as follows:
as shown in fig. 1, a network backup system for meteorological data, which is used for transmitting meteorological message data generated by a meteorological measuring machine provided in a lower meteorological department to a data receiving server provided in a higher meteorological department, includes:
the communication device is inserted in the weather measuring and reporting machine and is in communication connection with the wireless network through the weather measuring and reporting machine inserted with the communication device so as to realize that the weather measuring and reporting machine has the public network access capability; the communication device is also in communication connection with a wireless router or a mobile phone hotspot so as to realize that the weather forecast machine accesses the public network;
