For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0020] Please refer to the attached Figure 1 The present invention describes an environmental monitoring system for an unmanned offshore platform.

[0021] The current offshore platform environmental monitoring system is unable to support remote control of the air-conditioning operating status (on or off), working mode (automatic, cooling, heating, dehumidification, air supply), and remote adjustment such as temperature setting by land terminals.

[0022] Therefore, the environmental monitoring system of this offshore unmanned platform includes an environmental monitoring host, an environmental monitoring cabinet, an outdoor unit and an indoor unit. The environmental monitoring host is used to receive environmental monitoring data and transmit the data to a land data center. The environmental monitoring host is electrically connected to the environmental monitoring cabinet, and the environmental monitoring cabinet is electrically connected to the outdoor unit and the indoor unit. The environmental monitoring cabinet is used to monitor the data of the outdoor unit and the indoor unit, and the outdoor unit is electrically connected to the indoor unit.

[0023] Through this environmental monitoring system, the ventilation and air-conditioning system of the offshore platform can be monitored and controlled to ensure the normal operation of the equipment, and the parameters such as temperature and humidity, pressure, indoor and outdoor pressure difference and water immersion in each room meet the requirements.

[0024] Specifically, the environment monitoring system software is installed on the environment monitoring host.

[0025] By installing the environmental monitoring system software on the environmental monitoring host, configuration, programming, logic download and installation testing can be performed.

[0027] The outdoor unit and indoor unit are controlled by the main controller and the redundant controller.

[0028] Preferably, the main controller and the redundant controller are connected in parallel, and only one of the main controller and the redundant controller can be used, that is, the redundant controller is a backup controller for the main controller. When the main controller cannot be used, the redundant controller can replace the redundant controller for normal use.

[0029] Specifically, the main controller includes an AI module, a DI module, a DO module, an RS458 module and matching wiring terminals.

[0036] Furthermore, the indoor unit includes an indoor unit junction box and an indoor unit electrical control box. The indoor unit junction box is electrically connected to the environmental monitoring cabinet, so that the external unit electrical control box and the indoor unit electrical control box are controlled through the indoor unit junction box. The indoor unit electrical control box is electrically connected to the air supply fan and the electric heater.

[0037] Furthermore, a temperature and humidity sensor is electrically connected to the indoor unit junction box.

[0038] By setting up this environmental monitoring system, the operating status (on or off) and working mode (automatic, cooling, heating, dehumidification, air supply) of the air conditioner can be remotely controlled at the land terminal, as well as the temperature setting and other remote adjustments. When the temperature and humidity in the room exceed the limit alarm, the air conditioner can be automatically started or stopped, and the operating mode can be adjusted. Provide intelligent inspection for the platform, realize the five major applications of operation monitoring, operation and control, comprehensive information analysis and intelligent alarm, operation management, and auxiliary functions, and help platform maintenance personnel improve the efficiency and accuracy of room environment inspections.
