The invention provides an elevator operation height detection device and a system. The elevator operation height detection device comprises a control module and a height detection module, wherein the control module acquires elevator height information detected by the height detection module and sends the acquired elevator height information to the servo; the height detection module detects the elevator height information and sends the detected elevator height information to the control module; the elevator height information is acquired by the height detection module via the control module, and then the elevator height information is sent to the servor; and when the height of a closed elevator door is inconsistent to the current elevator height recorded by the height height information, potential safety dangers due to height differences existing between a compartment and the elevator door can be effectively alarmed, so managers of the elevator can immediately maintain the elevator having potential safety dangers.
