Environmental system control method and control system

The invention discloses an environmental system control method and control system. The method comprises the following steps: acquiring monitoring data and a current running state; determining a target operation state of the control mechanism at the next moment according to the monitoring data, the current operation state and the control strategy; and controlling the control mechanism to operate in the target operation state at the next moment. According to the invention, the operation state of the control mechanism is controlled through the remaining number of people, so that the environmental parameter requirements of people who are about to enter or already enter the space area on the space area are met in time; meanwhile, due to the fact that the operation state of the control mechanism is controlled in real time on the basis of the remaining personnel in the space area, energy waste caused by the fact that the remaining personnel still operate after leaving the environment system is avoided, and energy co
