Abstract

A controller for an elevator which can detect tailgating using a low-cost configuration and perform proper operation upon detection of tailgating. For this purpose, an ID checking device, a noncontacttype door sensor for detecting a user getting on a cage, and a weighing scale detection means for detecting a user in accordance with the deadweight of a cage are provided on the elevator. When use of the elevator by an identified person is detected by the ID checking device and when it is detected by both the noncontact type door sensor and the weighing scale detection means that a suspicious individual gets on a cage together with the identified person, it is judged that tailgating takes place. In the event of occurrence of tailgating, the controller controls the elevator to perform the specified operation for eliminating tailgating and for notifying occurrence of tailgating to the outside.

Description

technical field [0001] The invention relates to an elevator control device for detecting suspicious persons' tailgating. Background technique [0002] In recent years, crimes in elevators of public houses, condominiums, etc. have been increasing. Therefore, in order to exert the effect of suppressing crime, many elevators are provided with monitoring cameras in the car, and are provided with recording devices for recording the images of the monitoring cameras. On the other hand, recently, more and more apartments restrict the entry and exit of people other than residents by installing high-security security devices that require personal authentication based on password input and ID verification when entering the building. . [0003] But even if the above-mentioned apartment with higher security equipment is installed, it is difficult to completely prevent the entry of suspicious persons. For example, even if the above-mentioned preventive equipment is introduced into the ...
