Line valve chamber safety state detection method and system and computer equipment

The invention discloses a line valve chamber safety state detection method and system and computer equipment, and belongs to the technical field of access control systems. The method comprises the following steps: according to the state of a first access control contact, the state of a second access control contact and the state of an inspection switch, acquiring whether a person exists in a valve chamber or not; in response to the presence state of the valve chamber, obtaining the state of a first access control contact; in response to the closed state of the first access control contact, determining that the valve chamber is in a non-inspection state; in response to the fact that the first access control contact is in the disconnected state, determining the state of the inspection switch; responding to an off state of the inspection switch, and acquiring entering time; determining that the valve chamber is in a non-inspection state in response to the entry time greater than the allowed entry time; and in re
