The invention relates to the technical field of elevators, in particular to an elevator weightlessness unbalance alarm system and method.The elevator weightlessness unbalance alarm system comprises a main control computer, a balance monitoring device, a weightlessness monitoring device, an emergency stop device and an alarm device, and the balance monitoring device, the weightlessness monitoring device, the emergency stop device and the alarm device are all arranged on an elevator and electrically connected with the main control computer; the balance monitoring device is used for detecting whether the elevator is unbalanced or not, the weightlessness monitoring device is used for monitoring whether the elevator is weightlessness or not, the emergency stop device is used for controlling the elevator to brake when the elevator is unbalanced or weightlessness, and the alarm device is used for sending a signal to give an alarm after the emergency stop device acts. The elevator is monitored through the balance monitoring device and the weightlessness monitoring device, if the elevator is unbalanced during ascending and descending or weightlessness occurs during descending, the elevator is directly braked through the emergency stop device, then the alarm device gives an alarm to inform rescue workers to conduct rescue, and therefore the safety of the elevator is improved.

    本发明涉及电梯技术领域,尤其是指一种电梯失重失衡报警系统及方法,包括主控机、均设置于电梯的平衡监测装置、失重监测装置、急停装置以及报警装置,平衡监测装置、急停装置以及报警装置均与主控机电连接,平衡监测装置用于检测电梯是否失衡,失重监测装置用于监测电梯是否失重,急停装置用于在电梯失衡或失重时控制电梯刹停,报警装置用于在急停装置动作后发送信号进行报警。本发明通过平衡监测装置和失重监测装置对电梯进行监测,但电梯在升降时发生失衡或者下降时发生失重,则直接通过急停装置对其进行刹停,然后通过报警装置报警以通知救援人员进行救援,从而提升了电梯安全。
