The invention discloses an array arrangement type multi-point rapid stop device and belongs to the technical field of safety design of escalators. The array arrangement type multi-point rapid stop device comprises a power source, an emergency stop controller, a motor, a harness, movable positioning bodies, fixed positioning bodies, infrared imagers, stress sensors and an emergency stop button. The power source, the emergency stop controller and the motor are all arranged below an escalator. Steps of the escalator are driven through the motor to operate. The movable positioning bodies are arranged under the steps of the escalator respectively. The fixed positioning bodies are arranged below the steps of the escalator. Irregular pits are formed in the lower end faces of the movable positioning bodies. According to the array arrangement type multi-point rapid stop device, whether the steps of the escalator operate in the forward direction or the reverse direction can be judged through the fixed positioning bodies by monitoring the change of the pits in the lower end faces of the movable positioning bodies; when it is monitored that the steps of the escalator operate in the reverse direction, the emergency stop controller controls the motor to stop operating in time. The array arrangement type multi-point rapid stop device is reasonable in design, simple in structure and suitable for optimized design of loss reducing systems for escalator crowding accidents or escalator stampede accidents.
