Circuit system for protecting parking lot operating personnel

The utility model discloses a circuit system for protecting operating personnel in a parking lot, which comprises a safety module, the safety module comprises a confirmation module and a control module which are in wired connection, and the confirmation module comprises a first switch, a first protection position contact and a first non-protection position contact. The control module comprises an access control local controller, a card reader and an electric control lock, the access control local controller is connected with the card reader, the electric control lock, the first protection position contact and the first non-protection position contact, a static contact of the first switch is connected with the first non-protection position contact, and when a movable contact of the first switch is connected with the first protection position contact, the first switch is switched on; the confirmation module generates an activation signal, and the vehicle stops running; and the access control local controller is used for controlling the electric control lock to open the door when reading the card swiping information and the activation signal. According to the system, through the newly added confirmation module, the premise of ensuring that the access control local controller opens the door is that the switch is in the protection position and the vehicle stops running on the technical level, so that the safety coefficient is improved.
