The invention discloses a brake state detection device of passenger conveying equipment. The brake state detection device comprises a control device and a detection device, the detection device comprises a plurality of safety relays, the number of the safety relays is equal to or larger than that of the brakes, and a state feedback switch of each brake is connected with a coil of one safety relay. Normally open contacts of the safety relays connected with the brake are connected in series to form a brake state feedback signal A, and then the brake state feedback signal A enters the control device; normally-closed contacts of the safety relays connected with the brake are connected in series to form a brake state feedback signal B, and then the brake state feedback signal B enters the control device; and when the brake state feedback signal A and the brake state feedback signal B are the same, the control device judges that the brake state is abnormal.
