摘要
A system for error avoidance and automatic recovery is combined with the accurate and reliable transmission system. The present invention provides a multi-variable control system using remote control with a wireless communication system. A plurality of closed loop control systems are connected through the wireless communication system. A master controller monitors the closing of each of the loops in the system and stores information for the status of the control loops in a control table at a control center. When a state variable is transmitted to the control center, a master controller notes that the initial value of the closed loop control system has been set. When the control center sends a control action to equipment or a process this closes the loop, the master controller notes that the closed loop control system has been closed for a particular time. If the closed loop control system does not get a loop closed, the control center immediately detects it. Thereafter, an alternative control action can be performed by the system.
