Embodiment 1

[0022] see figure 1 As shown, the pedestrian load rate detection device of the escalator or moving walk includes:

[0023] The current detection module 1 is used to detect the current Iu, Iv, Iw in the power three-phase main power circuit of the escalator or moving walk.

[0024] The voltage estimation or detection module 2 is used for estimating or detecting the voltages Vu, Vv, Vw in the power three-phase main power circuit of the escalator or moving walk.

[0025] The current power calculation module 3 is connected with the current detection module 1 and the voltage estimation or detection module 2, and calculates the actual electric power Pow_Now at the detection point, that is, calculates the electric power Pow_Now of the current escalator or sidewalk operation.

[0026] The no-load state judging module 7 can automatically or manually judge whether the escalator or moving walk is in the no-load state.

[0027] The no-load power adjustment module 5 is connected with the ...

Embodiment 2

[0058] see figure 2 , the pedestrian load rate detection device for escalators or moving walks shown, which is compatible with figure 1 The difference is that the no-load state judging module 7 can automatically complete the no-load judgment without manually judging the no-load. In order to realize automatic completion of no-load judgment, sensors 14, 15 such as photoelectric switches, proximity switches, step mats, ultrasonic waves, and infrared sensors are installed at the upper and lower entrances of escalators or moving walks. Are there pedestrians using escalators or moving walks. When the pedestrian detection module 9 does not detect a pedestrian within a specific time, the unloaded state judging module 7 can automatically judge that the escalator or moving walk is in an unloaded state. At this time, the current electric power Pow_Now is compared with the no-load electric power Pow_NL. If they are inconsistent (the difference exceeds the threshold value), the no-load ...

Abstract

The invention discloses a pedestrian loading rate detecting device for an escalator and an autowalk. In the pedestrian loading rate detecting device, an electric power value of an escalator in current running is calculated by a current detecting module, a voltage estimating or detecting module and a current power calculation module; an electric power value of the escalator in full-load running is calculated by a running direction judging module and a full-load power calculation module; an electric power value of the escalator in no-load running is calculated by a no-load state judging module and a no-load power adjusting module; and an actual loading rate is calculated by a loading rate calculation module according to the full-load running electric power value, the no-load running electric power value and the current running electric power value. The pedestrian loading rate detecting device enables accurate loading rate calculation, can be adjusted automatically according to conditions of an escalator lifting height, an actual escalator mechanical resistance and the like, and is convenient to use.

Description

technical field [0001] The invention relates to escalators and moving walk systems, in particular to a pedestrian load rate detection device for escalators and moving walk systems. Background technique [0002] The load rate of the escalator or moving walk can reflect the number of pedestrians in the escalator or moving walk, and the detection of the load rate can make the escalator or moving walk choose suitable service modes such as stop standby, low-speed standby, high-speed operation, and medium-speed operation; At the same time, the load rate is provided to the entire monitoring system, making escalators and moving walks a part of the entire pedestrian conveying system; the monitoring system can obtain accurate data to monitor, analyze and allocate traffic flow to meet the increasing transportation efficiency and minimum energy consumption requirements. As customers' demand for traffic flow management increases, the monitoring of the load rate of escalators or moving w...
