Intelligent control terminal

The utility model provides an intelligent control terminal, which comprises a main control chip, a first interface driving chip, a second interface driving chip, a first relay, a second relay, a firstcommunication serial port, a second communication serial port and a triode. When the device is specifically applied; an existing automation system is connected through a first communication serial port; electrical equipment is connected through a second communication serial port; when the intelligent control terminal works normally, the main control chip is connected between the first communication serial port and the second communication serial port in series, the characteristic that the main control chip is provided with a plurality of communication ports is utilized, expansion of externalcommunication ports of electrical equipment is achieved, communication between the electrical equipment and more systems is facilitated, and meanwhile the defect that a serial port bus cannot carry out concurrent communication
