The invention discloses an industrial control information sending system. The industrial control information sending system comprises an independent power supply network, a base facility, a carrier wave potential device, and a bypass processor; the independent power supply network is used for providing all the equipment except for a SCADA system with electricity; the base facility is composed of amanagement level equipment, a base equipment, and an actuating equipment; the base facility is connected with the independent power supply network through the carrier wave potential device; the carrier wave potential device is capable of realizing modulating and demodulating of digital information; the bypass processor is used for gathering and distributing of monitoring data and control data among the base facilities through electric power line carrier communication, so that an industrial control information bypass which is different from the SCADA system is constructed for sending and receiving of information. According to the industrial control information sending system, multiple channel communication is adopted for industrial control information sending and receiving, so that systemoperation stability is increased greatly, and a problem in the prior art that system anti-interference capacity of single channel type industrial control information transmission mode is poor is solved.
