Problems solved by technology
[0002] At present, data acquisition systems based on wireless communication technology at home and abroad generally require the data center to have a static IP or to transfer data through an intermediate server to realize data transmission between the data center and the remote DTU. Using a static IP to build a system is too costly, while dynamic In the way of IP plus intermediate server transfer, the stability and security of data transmission are extremely dependent on third-party servers
[0003] In addition, users often face complex debugging work when using platforms provided by third parties to build wireless data monitoring platforms
And it generally only supports a single wireless network, so it cannot well adapt to the diverse application requirements on site

The invention discloses a remote data monitoring system based on a hybrid wireless network. The system comprises a data center, wherein the data center is accessed into the internet, the internet is communicated with an operator network, the operator network is communicated with a field device data node, the field device data node is respectively connected with a low real-time DTU, a high real-time DTU and a DTU gateway, the low real-time DTU is connected with a low instantaneity field device, the high real-time DTU is connected with a high instantaneity field device, the DTU gateway is connected with a short-distance wireless network base station, the short distance wireless network base station is connected with a plurality of short distance wireless network terminals through the short distance wireless network, the short distance wireless network terminal is connected with the field device. The remote data monitoring system based on the hybrid wireless network is capable of effectively constructing a remote data monitoring platform based on the hybrid network in the industrial control industry.
Description
technical field [0001] The invention relates to the technical field of data monitoring, in particular to a remote data monitoring system based on a hybrid wireless network. Background technique [0002] At present, data acquisition systems based on wireless communication technology at home and abroad generally require the data center to have a static IP or to transfer data through an intermediate server to realize data transmission between the data center and the remote DTU. The cost of building a system with a static IP is too high, while the dynamic In the way of IP plus intermediate server transfer, the stability and security of data transmission are extremely dependent on third-party servers. [0003] In addition, users often face complicated debugging work when building a wireless data monitoring platform using a platform provided by a third party. And it generally only supports a single wireless network, so it cannot well adapt to the diverse application requirements ...
