Embodiment Construction
[0026] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0027] Such as figure 1 The escalator generally includes a step belt 101 (or conveyor belt, that is, a sidewalk escalator) for carrying and transporting passengers, and is provided with wall panels 102 on both sides of the step belt 101, and the wall panel 102 is provided with a step belt. 101 synchronously moving handrails 103, step belts 101, and wall panels 102 enclose the passenger passage of the escalator. The exit and entrance of the passenger passage are also provided with a bed cover 104 connecting the escalator and the building floor. The escalator installs driving devices such as motors in the space below the bed cover; the underside of the baseboard 102 near the bed cover 104 is usually pro...

The invention discloses an anti-congestion escalator and a control method thereof. The anti-congestion escalator comprises a step belt and a conveying belt for bearing passengers, armrests and a bed cover plate; a weighing sensor for monitoring the load on the bed cover plate is mounted at the lower part of the bed cover plate in an outlet of the escalator; a monitoring sensor for monitoring if the passengers are on the step belt or the conveying belt is mounted in the outlet of the escalator; and an anti-congestion control board is connected with a main control board of the escalator, and judges if the escalator is congested according to detecting signals of the weighing sensor and the monitoring sensor and sends a deceleration signal or a stop signal to the main control board. Through detecting the load on the bed cover plate in the outlet of the escalator and if the passengers on the step belt or the conveying belt near the bed cover plate in the outlet and judging if the escalator is congested, the anti-congestion escalator is reliable in congestion identification and judgment and high in accuracy rate, can timely and automatically control deceleration or operation stop, guarantees personal safety of the passengers, and is safe and reliable.
Description
technical field [0001] The invention relates to elevator safety control technology, in particular to an anti-blocking escalator and a control method thereof. Background technique [0002] With the development of society, elevator equipment such as escalators (including moving walks) are used more and more in public places such as shopping malls, supermarkets, and subways, which facilitates people's lives. In order to ensure the safe use of escalators and moving walks, such equipment usually comes with a variety of safety systems and switches, such as power supply system outage protection, motor overload protection, stop button, emergency stop switch, handrail entrance and exit safety switch, etc. However, there are no safety settings and switches for special prevention of escalator or moving walk entrance and exit channel blocking accidents at present. If there are passengers stranded at the exit of the escalator or moving walk, because the escalator or moving walk continue...
