[0031] First refer to figure 1 A first embodiment of the present invention will be described through FIG. 3 . figure 1 Showing the structure of a double-deck elevator, the double-deck elevator 100 has two elevator cars that are paired up and down.

[0032] The upper elevator car (hereinafter referred to as "upper car") 101 is provided with at least an upper car passenger detection unit 102, an upper car notification unit 103, an upper car side elevator door 104, and an upper car operating panel 105. And the intercom device 106 in the upper car. The upper car passenger detection unit 102 is used to determine whether there are passengers in the upper car 101 , for example, a sensor camera or a weight sensor can be used to determine whether there are passengers. The upper car notification unit 103 is used to deliver various information to passengers, preferably by voice, and a loudspeaker or the like can be used. In addition to voice, image information and the like may be used...

[0086] Next, a second embodiment of the present invention will be described with reference to FIG. 4 . Figure 4. The functional structure with figure 1 The structure shown is the same. The two differ slightly in terms of control flow, but serve the same purpose.

[0087] Figure 4A and Figure 4B The shown control flow chart shows how to eliminate the abnormal state that the elevator "fails to start" due to a foreign object being stuck on the door guide rail of the lower car door 110 for some reason, so that the lower car door 110 cannot be closed. . The control flow shown in this control flowchart is started at predetermined time intervals, and the control content of each step will be described below.

[0088] (step S201)

[0089] The occurrence of various abnormal states is monitored in the elevator control device 400. In this step, it is detected that a foreign object is stuck on the door guide rail of the lower car door 110, so that the lower car door 110 cannot be c...

Abstract

The present invention provides a double-decker elevator which is capable of sending a message that passengers are kept in a normal lift car to the management center even if abnormality processing is carried out for the lift car in abnormality when passengers are kept in a normal lift car. If the slight abnormality can not be eliminated by a passenger, sends the information of the abnormality to the management center, and inform a manager of the condition that the slight abnormality can not be eliminated by a passenger. If the slight abnormality can not be eliminated by a passenger, sends the information of the abnormality to the management center, and inform a manager of the condition that the slight abnormality can not be eliminated by a passenger; and if the normal lift car having not abnormality is judged to have passengers in it, carries out abnormality processing for the lift car in abnormality and sends the information of the abnormality to the management center.

Description

technical field [0001] The present invention relates to a double-deck elevator in a building, in particular to a double-deck elevator with an operation monitoring device for monitoring the running state of the double-deck elevator and a notification device for informing passengers of necessary information. Background technique [0002] It is known that in order to ensure a larger passenger transport capacity, two elevator cars are arranged in pairs up and down, so that the two elevator cars are simultaneously lifted and lowered in the hoistway. In addition, a monitoring device for monitoring abnormalities and failures is installed in double-deck elevators, and when abnormalities or failures occur, various information (information about abnormalities or failures and guidance information) can be notified in order to allow passengers in the elevator car to leave the elevator as soon as possible. etc.) notification device, etc. [0003] In the above-mentioned double-deck elevat...
