The invention provides an intelligent video monitoring system for a fracturing ship, and relates to the technical field of offshore oil exploitation safety monitoring, the system comprises an acquisition unit, a transmission unit, a code stream forwarding unit, a first display unit, a second display unit and a remote access unit, the information acquisition module is used for acquiring information of an ocean platform, each layer of a cabin and fracturing operation equipment; the transmission unit is in communication connection with the acquisition unit and the code stream forwarding unit and is used for transmitting the information acquired by the acquisition unit to the code stream forwarding unit; the code stream forwarding unit is in communication connection with the first display unit, the second display unit and the remote access unit, the first display unit can display collected information conventionally through a display, and the second display unit can analyze the collected information and display the information at a team leader station; and the remote access unit can remotely check the collected information through the video gateway. The method is suitable for real-time safety management and control of complex scenes on an ocean platform and a ship.

A thermostat control system for monitoring and controlling environmental characteristics of a building includes a base station unit and a remote access unit continuously interfacing through instant wireless private direct connectivity. The system also includes a plurality of sensors that measure the environmental characteristics and provide the thermostat unit with the measurements.

This invention provides an optical telemetry and control method, apparatus, system, and electronic device. The method is applied to a remote access unit configured with a preset physical shielding structure, and includes: receiving a downlink control signal sent by a telemetry and control center via optical fiber; performing radio frequency filtering on the downlink control signal; up-converting the filtered signal, amplifying its power, and then transmitting it; receiving an uplink radio frequency signal transmitted by a skid; pre-filtering the uplink radio frequency signal; down-converting the filtered signal, performing electro-optical conversion, and then transmitting it via the optical fiber. This invention enhances the stability of the remote access unit in environments with strong electromagnetic interference and strong magnetic fields through a triple design of optical domain transmission, radio frequency filtering, and magnetic shielding, achieving highly reliable, low-latency telemetry and control communication, and overcoming the application limitations of traditional wireless technology in extreme environments.
