Problems solved by technology

If there is an error in the number of people present before opening the door, even if the number of people ascending and descending on the first floor can be detected 100% correctly, the number of people present after closing the door will not be correct
Then, the number of people present before opening the door depends on the number of people on the stairs and the number of people who got off the stairs before stopping on the first floor, so if there is only one false detection The number of people going up and down on each floor cannot accurately detect the number of people present after the door is closed on the first floor, and there is a problem that the error cannot be corrected afterwards (see Patent Documents 1 to 5)
[0024] And above-mentioned problem is not limited to elevator, generally speaking, there is above-mentioned problem equally for the number detection device in the enclosed space that people can come in and go out by door switch.

Embodiment approach 1

[0062] In this embodiment, for convenience of description, a typical example of "door opening and closing, and a closed space where people go up and down" is assumed to be an elevator.

[0063] figure 1 It is a block diagram showing the structure of the number detection device 1 for elevators of this embodiment. figure 1 The number detection device 1 includes: a measurement unit 11 ; a boarding and disembarking number estimation unit 12 ; a passenger presence / absence estimation unit 13 ; and a presence number estimation unit 14 . Among these units, in addition to the measurement unit 11 which is hardware, the respective units 12 to 14 are constituted by software on a microcomputer.

[0064] The measuring unit 11 is, for example, composed of a weight sensor, a photoelectric sensor, or a camera, or a combination thereof, which are installed on the elevator. The weight sensor, photoelectric sensor, or camera measure the load weight, detection results, or monitor images respectiv...

Embodiment approach 2

[0089] In Embodiment 1, the measuring unit 11 is not specified, but the number of people present after door closing of the elevator is estimated based on the number of people getting on and off the car and the result of the presence or absence of passengers.

[0090] But, for example, if each measuring unit used for estimating the number of people on board, the number of people getting off, and the presence or absence of passengers bears weight sensors, photoelectric sensors, and monitoring cameras, each measuring unit is set separately, then the number of people detection device 1 Import costs increase.

[0091] Therefore, in this embodiment, a method of estimating the number of people who boarded, the number of people who got off, and the number of people present with high accuracy using only the weight sensor is shown.

[0092] FIG. 4 is a block diagram showing the configuration of the number detection device 1 according to Embodiment 2 of the present invention. As shown i...

Deformed example 1

[0125]

[0126] exist Figure 6 In step ST205, the waveform observation unit 16 may use the next number estimation method (2) different from the above-mentioned number estimation method (1) to similarly estimate the number of people getting on and off the elevator.

[0127] That is, waveform observation section 16 sets a positive first threshold value for time difference data W_diff(i). In step ST205, the waveform observation unit 16 sets the first threshold at a predetermined position for the value of the received time difference data W_diff(i) greater than or equal to 0, and changes the time series of the time difference data W_diff(i) The number of times equal to or greater than the set first threshold (in other words, the number of times the time difference data W_diff(i) crosses the above-mentioned threshold in one of the upward and downward directions) is regarded as the "number of boarders".

[0128] For example, when in Figure 7 When the first threshold value is s...

Abstract

The present invention relates to a nose count apparatus and an elevator. Because the prior nose count counts noses according to the load bearing weight variation number and direction, it can not count if the weight variation is not linear stepped. In addition, the prior nose count has no mention to the precision of the present people. A measurement unit (11) measures the data used in the nose count. A passage presumption unit (12) presumes the number of passages. A passage existence presumption unit (13) presumes the passage existence in the enclosed space according to the measured data. A present passage presumption unit (14) resets the present passage to 0, when the existence presumption result is no; and presumes the present passage in the enclosed space according to a formula, {(the number of present passages before opening the door)+(the presumption result of passages taking on the elevator)-(the presumption result of passages taking off the elevator)}, when nonexistence existence presumption result is yes.

Description

technical field [0001] The present invention relates to a number detection device for detecting the number of people getting on the elevator, the number of people getting off the elevator, and the number of people present in a closed space such as an elevator. Background technique [0002] In order to improve the security function of an elevator, it is important to detect with high precision the number of people getting on the elevator, the number of people getting off the elevator, and the number of people present in the elevator. [0003] As a conventional number detection device, the patented invention described in Patent Document 1, for example, continuously measures the load weight of the car during a stop, filters the measured data, and determines the number of passengers in the elevator car based on the load weight data of the car. The invention of the number of people being transported, wherein the step-shaped change of the carrying weight generated during the stop i...
