If W∪V={x3, y3} or {x3, y2} or {x2, y3}, a general secondary recovery and recharge judgment signal is generated.

5. The recovery rate and recovery amount measurement and analysis system of a sulfur hexafluoride recovery and purification device according to claim 1, characterized in that: The specific steps for optimizing control analysis and processing are as follows: When a general secondary recovery and recharging determination signal is received, a primary control instruction is generated accordingly and sent to the execution terminal. When the execution terminal receives the primary control instruction, k1 time periods are added and temperature and pressure control processing operations are performed at the same time; When a moderate secondary recovery and recharging determination signal is received, a secondary control instruction is generated accordingly and sent to the execution terminal. When the execution terminal receives the secondary control instruction, k2 time periods are added and temperature and pressure control processing operations are performed at the same time; When a major secondary recovery and recharging determination signal is received, a third-level control instruction is generated accordingly and sent to the execution terminal. When the execution terminal receives the third-level control instruction, k3 time periods are added and temperature and pressure control operations are performed simultaneously, where k1<k2<k3.
