However, conventional methods such as filter processing and photosensitivity adjustment cannot always effectively suppress the occurrence of erroneous detection depending on the surrounding environment.

An automatic door system according to an embodiment of the present invention will be described in detail below with reference to the drawings. In addition, each embodiment shown below is an example of embodiment of this invention, Comprising: This invention is not limited to these embodiments and interpreted. In addition, in the drawings referred to in this embodiment, the same parts or parts having similar functions are denoted by the same reference numerals or similar reference numerals, and repeated description thereof will be omitted.

<First embodiment>
The first embodiment will be described below.
FIG. 1 is a diagram showing an automatic door system 1 according to a first embodiment of the invention. FIG. 2 is a bird's eye view showing the detection area 7 of the sensor system 3 according to the first embodiment of the invention. As shown in FIG. 1 , an automatic door system 1 includes an automatic door device 2 and a sensor system 3 . The automatic door system 1 opens the door 21 when the sensor system 3 detects a passerby or the like trying to pass through the door 21 shown in FIG.

[Configuration of automatic door device]
The automatic door device 2 drives and controls the motor based on the door 21 shown in FIG. and a door controller (not shown). In the example of FIG. 2, the two doors 21 are draw type sliding doors. However, the mode of the door 21 is not limited to the example of FIG. 2, and various types of doors such as a single sliding type sliding door, hinged door, folding door, or glide door may be employed.

For example, the sensor system 3 inputs a detection signal corresponding to detection of a passerby or the like within an effective detection area, which will be described later, to the door control unit. The door control unit performs control to drive the door 21 in the opening direction (hereinafter referred to as "open drive control") in response to the input of the detection signal.

[Configuration of sensor system]
As shown in FIG. 2, the sensor system 3 detects a passerby or the like at the door 21 at the center of the blind portion 24, more specifically at the boundary between the two doors 21 in the fully closed state. located above. Note that the sensor system 3 may be provided at a location other than the blind portion 24 such as the ceiling or the lower surface of the blind portion 24 .

As shown in FIG. 1 , the sensor system 3 includes a sensor 4 and a setting support section 5 . The configuration of the setting support unit 5 (5a) will be described later in detail. Sensor 4 is an automatic door sensor. The sensor 4 includes a detection section 41 and a sensor control section 42 . The sensor control section 42 is connected to the detection section 41 , the automatic door device 2 and the setting support section 5 . The sensor control unit 42 includes hardware such as a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). be. Note that at least part of the sensor control unit 42 may be configured by software.

The detector 41 is an optical sensor having a predetermined detection area 7 . As shown in FIG. 1 , the detection unit 41 includes a light projecting unit 411 and a light receiving unit 412 . The light projecting unit 411 includes an optical lens (not shown) for light projection and a plurality of light projecting elements (not shown). The light projecting unit 411 projects (irradiates) pulsed near-infrared light onto the detection area 7 from each of the plurality of light projecting elements. The light receiving section 412 has an optical lens (not shown) for light reception and a plurality of light receiving elements (not shown) optically corresponding to each of the plurality of light projecting elements of the light projecting section 411 . The light receiving unit 412 receives the near-infrared light projected onto the detection area 7 from each of the plurality of light projecting elements of the light projecting unit 411 by each of the plurality of light receiving elements, and the near-infrared light is received by each of the light receiving elements. Detect the amount of light received. The light receiving unit 412 outputs the detected amount of received light to the sensor control unit 42 as a detection signal having a signal value corresponding to the amount of received light (for example, an 8-bit signal value converted into a value from 0 to 255). .

Note that the light projecting unit 411 and the light receiving unit 412 may project and receive light other than near-infrared light. Further, the light projecting unit 411 and the light receiving unit 412 may use different optical systems instead of the optical lenses for light projection and light reception, or may not use optical lenses.

The sensor controller 42 has an effective sensing area. As shown in FIG. 2, the effective detection area is at least a part of the detection area 7, which is the area that can be detected using the sensor system 3, set for detecting a passerby at the door 21. is the area of 2 shows the positional relationship of the detection area 7 near the floor surface 8. As shown in FIG.

In the example of FIG. 2, the detection area 7 is composed of a plurality of small detection areas 71 spaced apart in the opening/closing direction d1 of the door 21 and in the front-rear direction d2 orthogonal thereto in front of the two doors 21. It is Specifically, in FIG. 2, there are a total of 72 small detection areas 71 of 6 columns×12.

Each small detection area 71 corresponds to an irradiation spot of near-infrared light projected from each of the plurality of light projecting elements of the light projecting section 411 and received by each of the plurality of light receiving elements of the light receiving section 412. .

The effective detection area in the example of FIG. 2 is composed of at least one small detection area 71 out of a plurality of small detection areas 71 . In addition, in the example of FIG. 2, each small detection area 71 has a circular shape. In this case, the diameter of the small detection area 71 on the floor surface 8 can be set to any value between 10 cm and 30 cm, for example. Note that the small detection area 71 may have a shape other than the circular shape, such as an elliptical shape, a rectangular shape, and a polygonal shape.

There are no particular limitations on which of the plurality of small detection areas 71 is set as the effective detection area. For example, the effective detection area may be set in advance before the automatic door system 1 is started to be used. Also, the effective detection area may be variable according to the door position or the like.

The sensor control unit 42 causes all the light projecting elements of the light projecting unit 411 to project near-infrared light toward the corresponding small detection areas 71 . Then, the sensor control section 42 causes all the light receiving elements of the light receiving section 412 to receive the reflected light of the near-infrared light from each small detection area 71 . Then, the sensor control section 42 extracts the detection signal of the effective detection area from the detection signals for each of the small detection areas 71 input from the light receiving section 412 .

Then, the sensor control unit 42 detects a passerby or the like based on the detection signal of the extracted effective detection area. Here, the sensor control unit 42 performs filtering on the detection signal using an erroneous detection suppression filter, and then detects a passerby or the like. By performing filtering, the influence of specific noise (for example, rainfall, snowfall, steam, exhaust gas, insects, puddles, etc.) is reduced, and the occurrence of erroneous detection is suppressed.

However, since there are a wide variety of noises present in the surrounding environment, filtering does not always prevent all erroneous detections. In addition, when excessively strong filter processing is performed, it is difficult to detect a passerby and the like, and the response to the opening operation of the door 21 becomes dull. Therefore, it is necessary to set the filter processing so that it has an appropriate strength for each small detection area 71 while avoiding setting the filter processing to be excessively strong.

In detecting a passerby, for example, the sensor control unit 42 stores, as a reference value, the signal value (that is, the amount of light received) of the detection signal in the effective detection area immediately after the power of the sensor system 3 is turned on. A passerby or the like may be detected based on the amount of change in the signal value with respect to the value. When a passerby or the like within the effective detection area is detected, the sensor control section 42 outputs a signal indicating the detection result to the automatic door device 2 . The automatic door device 2 performs opening driving control of the door 21 based on the acquired detection result.

Instead of causing all the light projecting elements of the light projecting part 411 to project near-infrared light, the sensor control unit 42 may cause only the light projecting elements corresponding to the effective detection area to project light. In this case, all of the small detection areas 71 onto which the near-infrared light is projected become effective detection areas. Power consumption is reduced by projecting light only to the light projecting elements corresponding to the effective detection area. Moreover, the life of the light projecting element is lengthened.

[Configuration of setting support part]
Even if filtering is performed uniformly using a specific false detection suppression filter, all false positives cannot necessarily be prevented because of the wide variety of noise that exists in the surrounding environment as described above. do not have. Therefore, it is desirable that the filtering process applied according to the surrounding environment is optimized. The optimization here means that the occurrence of false detection is prevented without slowing down the reaction of the drive control for opening the door 21 (that is, without causing a state in which the door 21 is difficult to open when a passerby or the like passes by). It is to suppress.

The setting support unit 5 (setting support device) acquires the detection signal extracted by the sensor control unit 42, analyzes the detection signal for each small detection area 71, and obtains information ( hereinafter referred to as "setting support information") is stored and output. The setting support information is, for example, information that specifies the small detection area 71 that is estimated to have a high possibility of false detection. The setting support information accumulated in the setting support unit 5 is periodically acquired by, for example, an operation manager of the automatic door system 1 . Then, the operation manager changes or adjusts the erroneous detection suppression filter used in the sensor control unit 42 based on the setting support information. This optimizes the setting of the filtering process and suppresses the occurrence of erroneous detection.

FIG. 3 is a block diagram showing the functional configuration of the setting support section 5a according to the first embodiment of the present invention. As shown in FIG. 3, the setting support unit 5a includes a storage unit 50a, a signal acquisition unit 51, a signal processing unit 52, a determination unit 53a, and an output unit .

The storage unit 50a stores information acquired from the signal acquisition unit 51, the signal processing unit 52, and the determination unit 53a. The storage unit 50a includes a non-volatile storage medium such as an SDD (Solid State Drive), an SD memory card, an HDD (Hard Disk Drive), or the like.

The signal acquisition unit 51 acquires a detection signal for each small detection area 71 from the sensor control unit 42 . The signal acquisition unit 51 outputs the acquired detection signal to the signal processing unit 52 . The signal acquisition unit 51 may temporarily store the acquired detection signal in the storage unit 50a, and the signal processing unit 52 may acquire the detection signal stored in the storage unit 50a.

The signal processing unit 52 acquires a detection signal for each small detection area 71 . The signal processing unit 52 performs filtering on the acquired detection signal using at least two types of erroneous detection suppression filters. The signal processing unit 52 causes the storage unit 50a to temporarily store information indicating the processing results of filtering by at least two types of false detection suppression filters. After that, the determination unit 53a acquires information indicating the processing result stored in the storage unit 50a. Note that the signal processing unit 52 may directly output information indicating the obtained processing result to the determination unit 53a.

The filtering process is, for example, a process of changing the threshold value by a false detection prevention filter in the detection process of determining the detection of a passerby or the like based on the comparison of the magnitude of the signal value indicated by the detection signal and a predetermined threshold value. . In general, the erroneous detection suppression filter makes the threshold value higher, and erroneous detection is less likely to occur. Moreover, the processing result of the processing by the signal processing unit 52 is, for example, information indicating whether or not the signal value indicated by the detection signal exceeds this predetermined threshold. That is, when the signal value indicated by the detection signal exceeds this predetermined threshold, it means that a passerby or the like has been detected at the position of the small detection area 71 that is the detection target.

The signal processing unit 52, for example, first executes filtering processing equivalent to the filtering processing performed by the sensor control unit 42 described above, and obtains a processing result. That is, the signal processing unit 52 executes the filtering process used for the current drive control for opening the door 21 (hereinafter referred to as "current filtering process") and obtains the processing result. Note that the signal processing unit 52 receives the current processing result, which is the processing result of the filtering processing executed by the sensor control unit 42, from the sensor control unit 42 instead of performing the current filtering process by itself and obtaining the processing result. You may make it acquire via the signal acquisition part 51. FIG.

Next, the signal processing unit 52 executes filtering with settings stronger than the current filtering (hereinafter referred to as “filtering to be compared”) to obtain a processing result. When the comparison target filtering process is executed, it is less likely to be determined that there is a passerby or the like than when the current filtering process is executed.

It should be noted that the “stronger” setting filter processing referred to here is a filter processing in which the above-described threshold value is set so as to make it more difficult to determine that a passerby or the like is present. The signal processing unit 52 performs filtering on the acquired detection signal using at least two types of erroneous detection suppression filters with different intensities. The signal processing unit 52 causes the storage unit 50a to temporarily store information indicating the processing results of filtering by at least two types of erroneous detection suppression filters with different intensities.

The determination unit 53a acquires the processing result of the current filtering process and the processing result of the filtering process to be compared, which are stored in the storage unit 50a. For each small detection area 71, the determination unit 53a compares the processing result of the current filtering process with the processing result of the comparison target filtering process. If the processing result of the current filtering process and the processing result of the filtering process to be compared are different, the determination unit 53a determines that the small detection area 71 to be detected is the small detection area 71 that is likely to cause erroneous detection. That is, if the processing result of the current filtering process indicates that a passerby or the like has been detected, but the processing result of the comparison target filtering process indicates that a passerby has not been detected, It is determined that the small detection area 71 to be detected is the small detection area 71 in which erroneous detection is likely to occur.

Note that this determination is generally based on a relatively large change in the amount of reflected light received by the light receiving unit 412 when a passerby or the like passes by, and when the cause is noise. This is based on the fact that the change in the amount of reflected light received by the light receiving section 412 is relatively small in many cases.

In the present embodiment, if the processing result of the current filtering process and the processing result of the filtering process to be compared differ even once, the determination unit 53a determines that the detection error is likely to occur in the small detection area 71. Although it is determined to be present, it is not limited to this mode. For example, the determination unit 53a may detect a small detection area 71 in which the number of times the processing result of the current filtering process differs from the processing result of the filtering process to be compared exceeds a predetermined number of times in a predetermined period of time. may be determined to be the small detection area 71 in which is likely to occur.
Further, in the present embodiment, the determination unit 53a determines that the small detection area 71 is likely to cause false detection based on the processing result of the current filtering process and the processing result of the filtering process to be compared. However, it is not limited to this aspect. For example, the determination unit 53a determines that the detection error is likely to occur in the small detection area 71 based only on the result of either the current filtering process or the filtering process to be compared during a predetermined period. good too.

The determination unit 53a temporarily stores information indicating the determination result (that is, information indicating the small detection area 71 where erroneous detection is likely to occur) in the storage unit 50a. After that, the output unit 54 acquires information indicating the determination result stored in the storage unit 50a. Note that the determination unit 53 a may directly output the information indicating the determination result to the output unit 54 .

The output unit 54 is, for example, a display unit (not shown) such as a liquid crystal display (LCD), or a communication interface for outputting the setting support information described above to an external device. The output unit 54 outputs, for example, setting support information (that is, information indicating the processing result of filtering by the signal processing unit 52, or the determination result of the determination by the determination unit 53a) in response to an instruction from the operation manager of the automatic door system 1. information) is output. Accordingly, the operation manager can change or adjust the false detection suppression filter used in the sensor control unit 42 based on the output setting support information.

Note that in the present embodiment, all the functional units included in the setting support unit 5a are provided in the sensor system 3, but the present invention is not limited to this aspect. For example, the storage unit 50a may be provided in a cloud server or an external device such as a handy terminal, and the operation manager may acquire the setting support information from these external devices.

Alternatively, for example, the setting support unit 5a may be provided in a server on the cloud. In this case, since the signal processing unit 52, the determination unit 53a, and the like are on the cloud, it becomes easy to change and adjust various processes in the signal processing unit 52, the determination unit 53a, and the like.

Alternatively, for example, among the functional units of the setting support unit 5a, the signal acquisition unit 51 and the signal processing unit 52 are provided on the sensor system 3 side, and the other functional units are provided on a server on the cloud. There may be. In this case, since the amount of data is reduced by the filtering process by the signal processing unit 52, compared to the case where all the function units of the setting support unit 5a are on the cloud, Communication traffic can be reduced.

Alternatively, for example, among the functional units included in the setting support unit 5a, the signal acquisition unit 51 and the signal processing unit 52 may be provided in a cloud server. In this case, the sensor setting support function of the setting support unit 5a can be retrofitted even to a conventional automatic door system in which the sensor system 3 or the automatic door device 2 does not incorporate a dedicated system (for example, the setting support unit 5a). can be added.
In this manner, in the case where a part of the function units provided in the setting support unit 5a is provided in a server on the cloud, the sensor system 3 has a communication function for performing communication between the server and its own device. Prepare.

Note that the storage unit 50a may collectively store the information indicating the processing result of the filtering process by the signal processing unit 52 (or the information indicating the determination result of the determination by the determination unit 53a) for each predetermined period. . As a result, the amount of information stored in the storage unit 50a can be reduced.

The storage unit 50a stores information indicating the processing result of filtering by the signal processing unit 52 (or information indicating the determination result of the determination by the determination unit 53a) for each operation state of the automatic door apparatus 2. good too. The operating state here means, for example, the operation modes of the automatic door device 2 such as a normal mode and a security mode. As a result, for example, the operation manager of the automatic door system 1 can change or adjust the erroneous detection suppression filter used in the sensor control unit 42 so as to be optimal for each operation state, based on the setting support information for each operation state. etc.

[Operation of setting support part]
An example of the operation of the setting support unit 5a will be described below.
FIG. 4 is a flow chart showing the operation of the setting support unit 5a according to the first embodiment of the present invention. The operation of this flowchart is executed each time a detection signal is transmitted from the sensor control unit 42 to the setting support unit 5a.

The signal acquisition unit 51 acquires a detection signal for each small detection area 71 from the sensor control unit 42 (step S001). The signal acquisition unit 51 outputs the acquired detection signal to the signal processing unit 52 . Next, the signal processor 52 performs the current filtering process and obtains the processed result. In addition, the signal processing unit 52 executes comparison target filtering, which is stronger than the current filtering, and obtains a processing result (step S002). The signal processing unit 52 outputs information indicating the processing result of the current filtering and information indicating the filtering result to be compared to the determining unit 53a.

The determination unit 53a compares the processing result of the current filtering process with the processing result of the filtering process to be compared (step S003). When the processing result of the current filtering process and the processing result of the filtering process to be compared are different (step S004: Yes), the determination unit 53a determines that the small detection area 71 to be detected is the small detection area 71 where false detection is likely to occur. (step S005). The determination unit 53a causes the storage unit 50a to store information indicating the determination result (step S006).

For example, when there is an output instruction from an external device or the like (step S007, Yes), the output unit 54 outputs information indicating the determination result stored in the storage unit 50a (step S008). Thus, the operation of the setting support unit 5a shown in the flowchart of FIG. 4 is completed.

As described above, the setting support unit 5a (setting support device) of the sensor system 3 according to this embodiment includes the signal processing unit 52 and the storage unit 50a.

Get each result. The storage unit 50 a stores a plurality of signal processing results obtained by the signal processing unit 52 .

With such a configuration, the setting support unit 5a can provide setting support information based on the processing results of at least two types of signal processing (filter processing) to, for example, an operation manager of the automatic door system 1. can. An operation manager or the like can change or adjust an erroneous detection suppression filter used in the sensor control unit 42 based on the setting support information. Thereby, the setting support unit 5a can effectively suppress the occurrence of erroneous detection by the sensor 4 .

<Modified Example of First Embodiment>
Modifications of the first embodiment will be described below.
The setting support unit 5a of the sensor system 3 according to the first embodiment described above stores the generated setting support information, and outputs the setting support information in response to an instruction from the operation manager of the automatic door system 1, for example. It is an aspect to do. Processing such as change or adjustment of the erroneous detection suppression filter used in the sensor control unit 42 is manually performed by an operation manager or the like. On the other hand, in this modified example, the setting support unit 5b automatically executes processing such as changing or adjusting the erroneous detection suppression filter used in the sensor control unit 42 without human intervention.

A general configuration diagram of the automatic door system and a bird's-eye view showing the detection area of the sensor system are the same as those in FIGS. The configuration of the setting support unit 5b according to this modification will be described below.

[Configuration of setting support unit]
FIG. 5 is a block diagram showing the functional configuration of the setting support section 5b according to the modification of the first embodiment of the present invention. As shown in FIG. 5, the setting support unit 5b (setting support device) includes a storage unit 50b, a signal acquisition unit 51, a signal processing unit 52, a determination unit 53b, a setting change unit 55, and an imaging unit 56. Prepare. The configurations of the signal acquisition unit 51 and the signal processing unit 52 are the same as those of the above-described first embodiment, so description thereof will be omitted. Also, regarding the configuration of the storage unit 50b and the determination unit 53b, the description will focus on the portions that differ from the configuration of the first embodiment described above.

The setting change unit 55 acquires information indicating the determination result stored in the storage unit 50b. The setting change unit 55 executes processing such as change or adjustment of the false detection suppression filter used in the sensor control unit 42 based on the acquired information indicating the determination result. Specifically, the setting change unit 55 identifies the small detection area 71 where false detection is likely to occur based on information indicating the determination result, for example. Then, the setting change unit 55 changes the setting of the filter processing so that the specified small detection area 71 is subjected to stronger filter processing than the conventional one. As a result, in the small detection area 71, the possibility of erroneous detection occurring is lower than in the conventional case.

In addition, a plurality of types of erroneous detection suppression filters are prepared in advance, and from among these, the setting change unit 55 performs erroneous detection such that stronger filtering than before is performed on the specified small detection area 71. A suppression filter may be selected as appropriate. Then, the setting change unit 55 may change the erroneous detection prevention filter used in the sensor control unit 42 to the selected erroneous detection prevention filter.

It should be noted that the determination by the determination unit 53b as to whether or not the small detection area 71 is likely to cause false detection is based on the processing result of the current filtering process generated by the signal processing unit 52 and the processing result of the filtering process to be compared. Not only based on the comparison result of , but also the analysis result of the image of the passage section of the automatic door device 2 and its surroundings may be used. Images used for analysis are not limited to still images, and may be moving images. This further improves the accuracy of determination as to whether or not the small detection area 71 is likely to cause false detection.

The imaging unit 56 images the passing section of the automatic door device 2 and its surroundings. The imaging unit 56 is, for example, a camera. In this modification, the sensor system 3 including the setting support unit 5b is installed in the vicinity of the automatic door device 2, so the setting support unit 5b is provided with the imaging unit 56. FIG. However, it is not limited to this mode, and if the imaging unit 56 is installed at a position where it can image the passing part of the automatic door device 2 and its surroundings (that is, the detection area 7), the installation position is Optional.

The imaging unit 56 compares the image information indicating the image captured at the same timing as the timing at which the detection signal is generated by the sensor control unit 42 to the processing result corresponding to the detection signal (that is, the processing result of the current filtering process). 5), and stored in the storage unit 50b as shown in FIG. 5, for example.

In this case, the determination unit 53b acquires the processing result of the current filtering process and the processing result of the filtering process to be compared, which are stored in the storage unit 50b. For each small detection area 71, the determination unit 53b compares the processing result of the current filtering process with the processing result of the comparison target filtering process. The determination unit 53a identifies a small detection area 71 in which the processing result of the current filtering process is different from the processing result of the filtering process to be compared.

Further, the determination unit 53b acquires image information associated with these processing results from the storage unit 50b. The determination unit 53b analyzes the image based on the acquired image information, and determines whether or not a passerby or the like appears in the small detection area 71 to be detected. As for the image analysis method, a general conventional method can be applied, so the description is omitted. Note that the determination unit 53b may store information indicating the analysis result of the acquired image in the storage unit 50b in association with the processing result. If it is determined by image analysis that a passerby or the like is not captured, the determination unit 53b determines that the small detection area 71 to be detected is the small detection area 71 that is likely to cause false detection.

Then, the determination unit 53b temporarily stores information indicating the determination result (that is, information indicating the small detection area 71 where erroneous detection is likely to occur) in the storage unit 50b. After that, the setting change unit 55 acquires information indicating the determination result stored in the storage unit 50b. Note that the determination unit 53 b may directly output information indicating the determination result to the setting change unit 55 . The setting change unit 55 executes processing such as change or adjustment of the false detection suppression filter used in the sensor control unit 42 based on the acquired information indicating the determination result.

As described above, the setting support unit 5b (setting support device) according to this modification includes the setting change unit 55 that changes the setting of the sensor 4 based on the determination result of the determination by the determination unit 53b. With such a configuration, the setting support unit 5b can continuously change or adjust the erroneous detection suppression filter used in the sensor control unit 42 without human intervention. Thereby, the setting support unit 5b can effectively suppress the occurrence of erroneous detection by the sensor 4. FIG.

Further, as described above, the setting support unit 5b according to this modification includes the imaging unit 56 that images the detection area 7, and the storage unit 50b stores images captured by the imaging unit 56 or analysis of the images. Store the result. With such a configuration, the setting support unit 5b can more accurately determine whether or not the small detection area 71 is likely to cause false detection. The setting support unit 5b can change or adjust the erroneous detection suppression filter used in the sensor control unit 42 with higher accuracy. Thereby, the setting support unit 5b can effectively suppress the occurrence of erroneous detection by the sensor 4. FIG.

<Second embodiment>
A second embodiment will be described below.
In the first embodiment and the modified example of the first embodiment described above, the setting support unit 5 performs a plurality of different filtering processes on the detection signal, and the occurrence of false detection is determined based on the comparison of the results of each process. It is a mode to suppress. On the other hand, in the second embodiment, the setting support unit 5 detects passers-by and the like with a plurality of different light sensitivity settings for the detection signal, and the occurrence of erroneous detection is prevented based on the comparison of each detection result. suppress.

A general configuration diagram of the automatic door system and a bird's-eye view showing the detection area of the sensor system are the same as those in FIGS. The configuration of the setting support unit 5c according to this modification will be described below.

FIG. 6 is a block diagram showing the functional configuration of the setting support section 5c according to the second embodiment of the present invention. As shown in FIG. 6, the setting support unit 5c (setting support device) includes a storage unit 50c, a signal acquisition unit 51c, a signal processing unit 52c, a determination unit 53c, and an output unit 54c.

The storage unit 50c stores information acquired from the signal acquisition unit 51c, the signal processing unit 52c, and the determination unit 53c. The storage unit 50c includes a non-volatile storage medium such as an SDD, SD memory card, HDD, or the like.

The signal acquisition unit 51 c acquires a detection signal for each small detection area 71 from the sensor control unit 42 . The signal acquisition unit 51c outputs the acquired detection signal to the signal processing unit 52c. The signal acquisition unit 51c may temporarily store the acquired detection signal in the storage unit 50c, and the signal processing unit 52c may acquire the detection signal stored in the storage unit 50c.

The signal processor 52c acquires a detection signal for each small detection area 71. FIG. The signal processing unit 52c stores the acquired detection signals in the storage unit 50c in chronological order for each small detection area 71 . The signal processing unit 52c acquires the detection signal for each small detection area 71 stored in time series from the storage unit 50c every predetermined period (for example, every 6 hours). For each small detection area 71, the signal processing unit 52c specifies the number of times a passerby or the like is detected within a predetermined period (for example, within 6 hours). Here, the signal processing unit 52c performs detection processing of a passerby or the like on the acquired detection signal with two types of light receiving sensitivity settings, and specifies each number of times.

The detection process is, for example, a process of determining whether or not the signal value indicated by the detection signal exceeds a predetermined threshold based on the set light sensitivity. Further, the processing result of the detection processing is, for example, information indicating whether or not the signal value indicated by the detection signal exceeds this predetermined threshold. That is, when the signal value indicated by the detection signal exceeds this predetermined threshold, it means that a passerby or the like has been detected at the position of the small detection area 71 that is the detection target.

For example, the signal processing unit 52c specifies the number of times a passerby or the like has been detected when detection processing based on light sensitivity settings equivalent to the detection processing performed by the sensor control unit 42 described above is performed. That is, the signal processing unit 52c specifies the number of detections when the current detection process (hereinafter referred to as "current detection process") used for the current drive control for opening the door 21 is executed. In addition, instead of performing the current detection process by itself and specifying the number of times, the signal processing unit 52c obtains the current processing result, which is the result of the detection process performed by the sensor control unit 42, via the signal acquisition unit 51c. It may be obtained and the number of detections may be specified.

Next, the signal processing unit 52c counts the number of detections when the detection process (hereinafter referred to as "comparison target detection process") is executed with a light sensitivity setting higher than that of the current detection process. Identify. Note that when the comparison target detection process is executed, the number of times it is determined that there is a passerby or the like increases more than when the current detection process is executed.

Here, an example of analysis of the detection signal will be described.
FIG. 7 is a diagram showing an example of detection signal analysis by the signal processing unit 52c according to the second embodiment of the present invention. In FIG. 7, the curve shows the change in signal value of the detection signal in time series. In this example, the signal value is 8-bit data that can take values from 0 to 255.

As shown in FIG. 7, in this example, the threshold for the light sensitivity setting used in the current detection process is 200 on the upper limit side and 10 on the lower limit side. That is, in the current detection process, when the signal value is out of the range of 10 to 200, it is determined that a passerby or the like has been detected. Similarly, the threshold value of the light sensitivity setting used in the detection process for comparison is 180 on the upper limit side and 20 on the lower limit side. That is, in the current detection process, when the signal value is out of the range of 20 to 180, it is determined that a passerby or the like has been detected. Therefore, in the case of the detection processing of the comparison target, since the light receiving sensitivity is set to be higher, passers-by and the like are more likely to be detected.

The reason why the two thresholds on the upper limit side and the lower limit side are set is that the received amount of reflected light may change in the direction of increasing and may change in the direction of decreasing. . For example, when a passerby wearing clothes with a brightness higher than the brightness of the floor surface 8 (for example, clothes with a brighter color) passes by, the amount of reflected light received increases. On the other hand, when a passerby wearing clothes with a brightness lower than the brightness of the floor surface 8 (for example, clothes with a darker color) passes by, the amount of reflected light received decreases.

In the detection signal illustrated in FIG. 7, when normal detection processing is performed, the number of times that a passerby or the like is detected is determined to be one. This is because, as shown in FIG. 7, the signal value exceeds the threshold value of the light sensitivity setting in normal detection processing only once (once on the upper limit side). On the other hand, when the comparison target detection process is performed, the number of times that a passerby or the like is detected is four. As shown in FIG. 7, the signal value exceeds the threshold value of the light sensitivity setting (higher sensitivity) in the detection process to be compared four times (three times on the upper limit side and one time on the lower limit side). is.

The signal processing unit 52c outputs information indicating the processing result of detecting a passerby by two types of light sensitivity settings for each small detection area 71 (that is, information indicating the number of times the threshold is exceeded within a predetermined period). , is temporarily stored in the storage unit 50c. After that, the determination unit 53c acquires information indicating the processing result stored in the storage unit 50c. Note that the signal processing unit 52c may directly output information indicating the obtained processing result to the determination unit 53c.

The determination unit 53c acquires the processing result of the current detection process and the processing result of the detection process to be compared, which are stored in the storage unit 50c. For each small detection area 71, the determination unit 53c compares the result of the current detection process with the result of the detection process to be compared. Based on the difference between the processing result of the current detection processing and the processing result of the comparison target detection processing, the determination unit 53c determines whether the small detection area 71 to be detected is a small detection area 71 that is highly likely to cause an erroneous detection. Determine whether or not there is

Specifically, for example, the determination unit 53c determines that the difference between the number of times the threshold is exceeded in the case of the detection process to be compared and the number of times the threshold is exceeded in the case of the current detection process is a predetermined number (for example, two times). If it exceeds, it is determined to be the small detection area 71 in which there is a high possibility of erroneous detection. In the case of the example shown in FIG. 7, the above difference is 3 times (4 times-1 time). Therefore, if the predetermined number is two, the small detection area 71 to be detected is determined to be the small detection area 71 that is highly likely to cause false detection.

Note that this determination is generally based on a relatively large change in the amount of reflected light received by the light receiving unit 412 when a passerby or the like passes by, and when the cause is noise. This is based on the fact that the change in the amount of reflected light received by the light receiving section 412 is relatively small in many cases.

The determination unit 53c temporarily stores information indicating the determination result (that is, information indicating whether or not erroneous detection is likely to occur for each small detection area 71) in the storage unit 50c. After that, the output unit 54c acquires information indicating the determination result stored in the storage unit 50c. Note that the determination unit 53c may directly output the information indicating the determination result to the output unit 54c.

The output unit 54c is, for example, a display device such as a liquid crystal display, or a communication interface for outputting the setting support information described above to an external device. The output unit 54c outputs setting support information (that is, information indicating the processing result of the detection processing by the signal processing unit 52c, or the determination result of the determination by the determination unit 53c) in response to an instruction from the operation manager of the automatic door system 1, for example. information) is output. Accordingly, the operation manager can adjust the light sensitivity setting used in the detection process by the sensor control unit 42 based on the output setting support information.

Note that in the present embodiment, all the functional units included in the setting support unit 5c are provided in the sensor system 3, but the present invention is not limited to this aspect. For example, the storage unit 50c may be provided in a server on the cloud or an external device such as a handy terminal, and the operation manager may acquire the setting support information from these external devices.

Alternatively, for example, the setting support unit 5c may be provided in a server on the cloud. In this case, since the signal processing unit 52c, the determination unit 53c, and the like are on the cloud, it becomes easy to change and adjust various processes in the signal processing unit 52c, the determination unit 53c, and the like.

Alternatively, for example, among the functional units of the setting support unit 5c, the signal acquisition unit 51c and the signal processing unit 52c are provided on the sensor system 3 side, and the other functional units are provided on a server on the cloud. There may be. In this case, since the amount of data is reduced by the detection processing by the signal processing unit 52c, compared to the case where all the functional units of the setting support unit 5c are on the cloud, the communication between the sensor system 3 and the server on the cloud Communication traffic can be reduced.

Note that the storage unit 50c may collectively store only the information indicating the processing result of the detection processing by the signal processing unit 52c (or the information indicating the determination result of the determination by the determination unit 53c) for each predetermined period. . As a result, the amount of information stored in the storage unit 50c can be reduced.

The storage unit 50c stores information indicating the processing result of detection processing by the signal processing unit 52c (or information indicating the determination result of determination by the determination unit 53c) for each operation state of the automatic door apparatus 2. good too. The operating state here means, for example, the operation modes of the automatic door device 2 such as a normal mode and a security mode. As a result, for example, the operation manager of the automatic door system 1 can adjust the light sensitivity setting used in the detection process by the sensor control unit 42 so as to be optimal for each operation state, based on the setting support information for each operation state. etc.

FIG. 8 is a flow chart showing the operation of the setting support unit 5c according to the second embodiment of the present invention. The operation of this flowchart is performed, for example, every predetermined period (for example, every 6 hours).

The signal processing unit 52c acquires the detection signal for each small detection area 71 stored in chronological order for a predetermined period (for example, the last 6 hours) from the storage unit 50c (step S101). Next, the signal processing unit 52 specifies the number of times a passerby or the like is detected when the current detection process is executed. In addition, the signal processing unit 52 specifies the number of times a passerby or the like is detected when the comparison target (higher sensitivity) detection process is executed (step S102). The signal processing unit 52c outputs information indicating the processing result of detecting a passerby by two types of light sensitivity settings for each small detection area 71 (that is, information indicating the number of times the threshold is exceeded within a predetermined period). , is temporarily stored in the storage unit 50c.

The determination unit 53c acquires information indicating the processing results stored in the storage unit 50c, and compares the number of times the threshold is exceeded in the case of the current detection process with the number of times the threshold is exceeded in the case of the detection process to be compared. (step S103). If the difference between the number of times the threshold is exceeded in the case of the detection process to be compared and the number of times the threshold is exceeded in the case of the current detection process exceeds a predetermined number (Step S104, Yes), the determination unit 53c It is determined that the small detection area 71 is highly likely to cause an erroneous detection (step S105). The determination unit 53c temporarily stores information indicating the determination result (that is, information indicating whether or not false detection is likely to occur for each small detection area 71) in the storage unit 50c (step S106).

For example, when there is an output instruction from an external device or the like (step S007, Yes), the output unit 54 outputs information indicating the determination result stored in the storage unit 50c (step S108). Thus, the operation of the setting support unit 5c shown in the flowchart of FIG. 8 is completed.

The storage unit 50c stores a plurality of signal processing results obtained by the signal processing unit 52c.

With such a configuration, the setting support unit 5c can provide setting support information based on the processing results of at least two types of signal processing (detection processing) to, for example, an operation manager of the automatic door system 1. can. An operation manager or the like can adjust the light sensitivity or change or adjust an erroneous detection suppression filter used in the sensor control unit 42 based on the setting support information. Thereby, the setting support unit 5c can effectively suppress the occurrence of erroneous detection by the sensor 4 .

For example, similarly to the setting changer 55 of the setting supporter 5b according to the modification of the first embodiment, the setting supporter 5c in the second embodiment may be configured to include a setting changer. Accordingly, the setting support unit 5c can adjust the light receiving sensitivity or change or adjust the false detection suppression filter used in the sensor control unit 42 without human intervention.
