TC-CCR014 97197975-A01 Remote Bidirectional Communication

TC-CCR014 97197975-A01’s on-site monitoring point is automatically controlled by PLC and relevant information is collected, which is connected to GSM DTU terminal through RS232 or RS485 interface, and the equipment information collected by PLC is processed and protocol encapsulated by GSM DTU terminal and sent to GSM wireless network.

The monitoring centre of TC-CCR014 97197975-A01 adopts the public network access solution server to access the Internet by public network, such as ADSL dial-up/telecommunication leased line broadband Internet access, etc., and apply for fixed IP address of the public network; small and medium-capacity system applications can be realized. The server adopts the DDN line provided by the provincial mobile communication company, applies for the configuration of fixed IP address, and connects with the GSM SMS remote control module. As the DDN line can provide higher bandwidth, when the number of PLC on site increases, the centre can meet the demand without capacity expansion, and it can realize the application of high-capacity system.

The server of TC-CCR014 97197975-A01 accepts the data coming from GSM SMS remote control module and then carries out AAA authentication first, and then transmits it to the host computer of the monitoring centre, and then displays the data restoration and data processing through the system software, which further strengthens the security of the system data communication.
