Abstract

PURPOSE:To prevent such a situation as short loading as little as possible as securing safety for passengers at time of selecting the operating direction by selecting the operating direction of an escalator stepwise according to a train position so as to take precedence of a flow of passengers alighting from a train, attributable to temporary congestion. CONSTITUTION:When a fact that a train 2 comes nearer is detected by an arrival pre-information detector 14, information broadcasting for travel direction control is performed by a speaker 11 via broadcasting equipment 21 to select an escalator 6 to down operation when it is traveling the up direction. Next, the presence of escalator passengers coming to a reverse flow against passengers stepped down from the train 2 is confirmed by output of a lower side passenger detector 12. When this lower side passenger detector 12 outputted the detected result that there are passengers, whether the train 2 has arrived or not is judged by an arrival track detector 15 after operating a buzzer so as not to produce any short loading of the passengers due to having the operating direction reversed in the midway.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention provides an escalator that is installed between a station platform and the ground, from the platform to the ground.
The present invention relates to an escalator control device that can selectively operate in the opposite direction.

(Prior Art) Conventionally, escalators that connect the platform and ground level of elevated railway or subway stations, etc., have generally been installed at one end of the stairs to save space and reduce the effort of passengers. Considering this aspect, it has become mainstream to provide services only in the upward direction.

However, with this system, the escalator only operates in one predetermined direction, regardless of passenger flow or usage conditions, such as during morning and evening rush hours or during daytime off-peak hours, so the operating direction of the escalator does not match the flow of passengers. may end up in the opposite direction, resulting in a decline in service. Constantly driving in one direction even during off-peak hours during the day is undesirable from the perspective of energy conservation.

To deal with this, a passenger detector is installed on the entrance side of the escalator to detect passengers, and the output of the passenger detector automatically operates the escalator for a predetermined period of time, thereby saving energy during off-peak hours. A method has also been proposed in which the operation is started by transmitting and receiving an arrival signal (1983-
(See Publication No. 83371). However, this method
This is a one-way automatic operation system, and the overall operation may be in the opposite direction to the direction of passenger flow. In such cases, transportation efficiency will decline, resulting in a decline in service.

It is also possible to improve transportation efficiency by automatically switching the driving direction according to the direction of passenger flow, but this has the disadvantage of ensuring the safety of passengers when changing the driving direction.

(Problems to be Solved by the Invention) In light of the above, an object of the present invention is to provide an escalator control device that can save space, save energy, and improve transportation efficiency while ensuring the safety of passengers. purpose.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, an escalator control device of the present invention includes a first detector that emits a first signal when a train approaches a predetermined distance toward a platform; a second detector that emits a second signal when the train arrives at a predetermined position on the platform; a third detector that emits a third signal when the train stops at a stop position on the platform; a first means for operating the escalator in the direction from the ground to the platform; a second means for stopping the escalator in response to a second signal; and a third means to operate the escalator in the direction from the platform to the ground in response to a third signal. The present invention is characterized by comprising a third means.

(Function) According to the above configuration, when a train approaches the platform, the operating direction of the escalator is adjusted according to the train position so as to give priority to the flow of passengers getting off the train, which causes temporary congestion. Since the changeover is performed in stages, it is possible to prevent the situation of unloaded items as much as possible while ensuring the safety of passengers when changing the driving direction.

(Example) Hereinafter, the present invention will be described with reference to one embodiment.

FIG. 2 shows the structure of a station equipped with escalators to which the present invention is applied. Note that Figure 2 shows the case of an elevated railway, and the train 2 is on track 3 of the elevated railway.
It receives power from the overhead wire 4 and runs on it. Here, a plurality of trains are illustrated as trains 2. Passengers 5 move up and down between ground level 7 and station platform 8 using escalators 6. Guidance fences 9 and 10 are provided at each entrance on the ground side and platform side of the escalator 6, respectively. A speaker 11 is provided near the escalator 6 for transmitting various guidance information to the passengers 5.

A plurality of detectors are arranged for the above-mentioned basic structure to control the escalator. That is, a ground side passenger detector 12 is provided near the ground side entrance/exit of the escalator 6, and an upper passenger detector 13 is provided near the platform side entrance/exit. An arrival prediction track detector 14 is provided to detect that a train is approaching a predetermined position on the side, and an arrival track detector 15 is provided in the center of the platform 8 to detect the arrival of the train 2 to the platform 8. A stop track detector 1 at the tip of the platform 8 detects the stop of the train 2.
6 is provided.

Figure 1 shows the escalator 6 based on the detection signal of each detector.
FIG. 2 is a block diagram of an escalator control device 20 that determines and controls an appropriate driving direction of the escalator.

Escalator control device 20 includes a control circuit 22 having a CPU. The output signal of the arrival trajectory detector 15 is directly introduced into this control circuit 22, and each output signal of the lower passenger detector 12, upper passenger detector 13, and stop trajectory detector 16 is input to the OR circuit 23.22. introduced via.

Next, the operation of the apparatus shown in FIGS. 1 and 2 will be explained with reference to the flowchart shown in FIG.

First, when the train 2 is traveling in the direction of the arrow P, it is determined whether it has approached the platform 8 based on the output signal of the arrival forecast trajectory detector 14 (step 30).
. If the train 2 is not approaching within the predetermined distance of the platform 8 (step 30: "No"), the passenger's use of S-Force Seek is determined based on the output signals of the lower passenger detector 12 and the upper passenger detector 13. The operating direction of the escalator 6 is determined according to the determination result.

That is, both the upper and lower passenger detectors 13 and 12 do not detect a passenger (steps 31 and 32: both “NO”).
”), the process returns to the initial state (step 30). When the lower passenger detector 12 issues a detection signal indicating the presence of a passenger before the upper passenger detector 13 (step 31: 'YE
S”) operates the escalator 6 in the upward direction (
Step 33). This upward operation is performed for a certain period of time.

Therefore, a timer (not shown) is started at the same time as the ascending operation starts, and the operating time is checked (step 3).
4). After a certain period of time has elapsed, the escalator is stopped (step 50). The lower passenger detector 12 does not detect a passenger (
When the upper passenger detector 13 detects a passenger (Step 32: "YES"), the upper passenger detector 13 detects a passenger in the same manner as when the lower passenger detector 12 detects a passenger. 13 issues an operating signal to operate the escalator 6 in the downward direction (step 35), and at the same time, a timer is started and the operating time is checked (step 36).

In this case as well, the escalator is stopped after a certain period of time has passed (step 50).

When the arrival forecast track detector 14 detects that the train 2 is approaching (step 30: "YES"), the escalator 6 is traveling in the upward direction (step 37: "
YES"), the speaker 1 is transmitted through the broadcasting equipment 21 in order to switch the escalator 6 to descending operation.
After the escalator 6 is not running in the upward direction (step 37: "NO"), the escalator 6 broadcasts the information that the train is approaching (step 38). Step 39), after calling the attention of each escalator passenger, the presence or absence of escalator passengers whose flow is in the opposite direction to the passengers who got off the train 2 is confirmed by the output of the lower passenger detector 12 (step 40) . At this point, when the lower passenger detector 12 outputs the detection result that there is a passenger (step 40: "YES"), a buzzer etc. After the person alarm device (shown in the figure) is activated (step 41), and when the detection result of the presence of a passenger is not output (step 40: “No
”), the arrival track detector 15 immediately determines whether the train 2 has arrived at the center of the platform 8 (step 42).When it is determined that the train 2 has arrived at the center of the platform 8 (step 42: “YES”) is
After the escalator 6 is forcibly stopped after a predetermined time (step 43), and if it is determined that the escalator 6 has not arrived at the center (step 42: “No”), the train 2 immediately returns to the predetermined position on the platform 8. It is determined again based on the output signal of the stop trajectory detector 16 (step 44). When it is determined that the train has not arrived at the predetermined position (step 44:
If "No"), the process returns to step 40 and repeats each of the following steps. When it is determined that the train 2 has arrived at the predetermined position on the platform 8 (step 44:
If "YES"), the escalator 6 is automatically operated in the downward direction (step 45), and priority is given to the downward operation for passengers who have gotten off the train 2. It is checked whether a predetermined time has elapsed since the last passenger who got off the train 2 passed the upper passenger detector 13 (step 46), and unless the predetermined time has elapsed (step 46: "No"), the train moves in the descending direction. (Step 45) continues. When the predetermined time has elapsed (step 46: "YES"), the escalator 6 is stopped (step 50).

After the escalator 6 stops (step 50), the process returns to the initial state, that is, the first step 30, and the steps described above are repeated.

In the above embodiment, when changing the driving direction, a guidance announcement and a reversing person warning system are used to alert passengers, but in order to do this more completely, it is necessary to mechanically prevent the vehicle from approaching from one direction. It is also possible to provide a lock bar at the entrance to prevent this.

Furthermore, although the above embodiment has been described in the case of an elevated station building, the same effect as described above can be achieved even when installed in a subway by simply reversing the vertical direction.

According to the embodiments described above, by automatically switching the driving direction in response to the flow of passengers that changes depending on the operating status of the train, it is possible to improve the transportation efficiency of the escalator,
By broadcasting the changeover guidance when the driving direction is changed, it is possible to ensure the safety of passengers, and furthermore, when the driving direction is changed, it is possible to issue a reverse passenger warning to new passengers to prevent passengers from being left behind.

〔Effect of the invention〕

According to the present invention, when a train approaches a platform, the operating direction of the escalator is changed in stages according to the train position so as to give priority to the flow of passengers getting off the train, which causes temporary congestion. Therefore, while ensuring the safety of passengers when changing the driving direction, it is possible to prevent items from being left unloaded as much as possible.
