Description

  The present invention relates to a remote monitoring device.

  The elevator car is equipped with an air conditioner (hereinafter referred to as “air conditioner”) for adjusting the temperature in the car so that passengers in the car can use the elevator comfortably. . The air conditioner measures the temperature in the car and performs control according to the difference between the measured temperature and the set temperature in order to maintain the temperature in the car at a preset temperature. Yes.

  In many cases, the air conditioner measures the temperature of the air to be taken in, and adjusts the temperature of the air to be blown out according to the measurement result. However, in general, the temperature distribution in the place where the air conditioner adjusts the temperature varies depending on the situation of the place. For this reason, there is an air conditioner that can be adjusted to a temperature comfortable for a person in a specific position among the air conditioners. As the air conditioner, there is one described in Patent Document 1, for example.

  The air conditioner (air conditioner) disclosed in Patent Document 1 is described as follows: “An imaging device that captures an image of a room in which an indoor unit is installed and an image captured by the imaging device are input as image data. Control means for extracting information on temperature and humidity by recognition, temperature / humidity display means for measuring and displaying temperature and humidity in the room where the indoor unit is installed, and the control means The display means is extracted by the image recognition, and air conditioning control is performed based on temperature and humidity information displayed on the temperature / humidity display means ”.

  Currently, many devices such as air conditioners are equipped with an abnormality diagnosis function that detects an abnormality by itself. Devices equipped with an abnormality diagnosis function usually stop automatically when an abnormality is detected. There are also devices that are configured to notify an external device connected via a network that an abnormality has been detected.

  However, the abnormality diagnosis function cannot detect all abnormalities. Even if the abnormality diagnosis function cannot detect an abnormality, the device may be operating abnormally. In the air conditioner provided in the elevator car, the difference between the temperature in the car and the set temperature may become very large due to an abnormality (here, including a failure) that the air conditioner itself cannot detect.

  The elevator may be used by many people. The car when going up and down is a closed room. For this reason, for example, in the season when the temperature rises, if the cooling capacity of the air conditioner decreases, the temperature in the car becomes high, and there is a risk that the passengers in the car will be remarkably uncomfortable. .

  The temperature in the car may become high due to the inflow of hot outside air. As a result, even if the temperature in the car becomes high, in other words, even if the temperature recognized by the air conditioner becomes high, the air conditioner does not always have an abnormality. . From this, it can be said that it is important to consider the use status of the elevator in order to more appropriately determine whether or not an abnormality has occurred in the air conditioner installed in the elevator car.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a technique for determining the presence or absence of an abnormality in an air conditioner provided in a car in consideration of an elevator usage situation. is there.

  In order to achieve the above object, a representative present invention is a remote monitoring device used for monitoring an elevator, and a temperature recognition unit for recognizing a temperature in a car whose temperature is adjusted by an air conditioner; A situation recognizing unit for recognizing the use situation of the elevator, and an abnormality determining unit for judging whether or not the air conditioner is abnormal based on the temperature recognized by the temperature recognizing unit and the use situation recognized by the situation recognizing unit And a notification control unit for notifying the abnormality when the abnormality determination unit determines that the abnormality is present in the air conditioner.

  According to the present invention, the presence / absence of an abnormality of an air conditioner provided in a car can be determined with higher accuracy in consideration of an elevator usage situation. Problems, configurations, and effects other than those described above will be clarified by the following description of the embodiments.

It is a figure explaining the construction example of the remote monitoring system to which the remote monitoring apparatus by this embodiment was applied. It is a figure explaining the structural example of measurement result information used for determination of generation | occurrence | production of abnormality by an air conditioner, and measurement result total information. It is a flowchart which shows the example of a temperature measurement process. It is a flowchart which shows the example of an aggregation / abnormality determination process.

  Hereinafter, embodiments of a remote monitoring apparatus according to the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a construction example of a remote monitoring system to which the remote monitoring device according to the present embodiment is applied. First, the remote monitoring system will be specifically described with reference to FIG.

  This remote monitoring system is a system constructed to remotely monitor the operating state of an elevator provided in a building such as a building and the state of equipment of the elevator. As shown in FIG. 1, the remote monitoring system is constructed such that an elevator remote monitoring device 2 installed in each building and a monitoring server 6 are connected to a network 5. Although only one remote monitoring device 2 is shown in FIG. 1, the remote monitoring device 2 is installed for each building, and usually many remote monitoring devices 2 are connected to the network 5.

  The elevator raises and lowers the car 1 under the control of the control device 3. An air conditioner 11 for adjusting the temperature in the car 1 is installed on the upper part of the car 1. Inside the car 1, a security camera (photographing device) 12 for photographing passengers and the like in the car 1, and a medium 13 whose state, for example, color changes depending on temperature, are provided.

  From the viewpoint of crime prevention, the camera 12 is provided on the back side (opposite side of the door) so as to be able to photograph the face of a passenger riding in the car 1. As a result, the door and its surroundings can be photographed.

  The medium 13 is provided at a position where the image can be captured by the camera 12 and a position where the image capturing is not hindered by a passenger or the like, for example, at an upper portion on the door side. Thereby, in this embodiment, the temperature in the car 1 is specified (recognized) from the medium 13 photographed by the camera 12, and the specified result is used for temperature adjustment control of the air conditioner 11. .

  The air conditioner 11 is often installed as an option. As a result, there are many cases where a location for attaching a temperature measurement sensor is not prepared in advance. For this reason, if an attempt is made to attach a sensor connected to the air conditioner 11, the installation may take time. In addition, when replacing the air conditioner 11, it is common to design according to the newly installed air conditioner 11 and to secure the installation location, etc., so it is necessary to design the wiring of the signal lines connected to the sensor May occur.

However, as in the present embodiment, when the temperature in the car 1 is specified from the image of the medium 13 taken by the camera 12, it is not necessary to provide a sensor by installing the air conditioner 11 regardless of whether or not it is replaced. It can be avoided. Therefore, the air conditioner 11 can be installed at a lower cost regardless of whether or not it is replaced.
The medium 13 itself is not particularly limited as long as its state such as color changes depending on the temperature.

  The car 1 is operated under the control of the elevator control device 3. The control device 3 recognizes the contents of the operation performed on the operation panel (not shown) provided in each platform and the operation panel (not shown) provided in the car 1, and the recognition result The control reflecting the above is performed, and the car 1 is moved up and down.

  The remote monitoring device 2 is a device for monitoring the operation status of various facilities including the control device 3 and the air conditioner 11. The monitoring result is transmitted to the monitoring server 6 via the network 5.

  The monitoring server 6 is an information processing apparatus for monitoring installed in a monitoring center or the like prepared for management and monitoring of an elevator that has made a maintenance contract. When the monitoring server 6 is notified from any of the remote monitoring devices 2 that the elevator has been stopped (including confinement of passengers in the car 1), equipment failure, etc., maintenance personnel can operate the necessary information. The data is transmitted to a maintenance information processing apparatus (not shown) via the network 5. Thereby, the monitoring server 6 makes the maintenance person recognize that it is necessary to deal with the elevator in which the situation occurs when the situation that the maintenance person should deal with occurs.

  The air conditioner 11 is, for example, a device (equipment) equipped with an automatic diagnosis function. When an abnormality is detected, the air conditioner 11 notifies the remote monitoring device 2 of the occurrence of the abnormality. The remote monitoring device 2 uses the temperature in the car 1 specified from the medium 13 to determine whether the air conditioner 11 is abnormal. Accordingly, when it is determined that an abnormality has occurred, the remote monitoring device 2 notifies the monitoring server 6 via the network 5 to that effect.

  As shown in FIG. 1, the remote monitoring device 2 has a functional configuration relating to determination of whether or not an abnormality has occurred in the air conditioner 11, as shown in FIG. 1, an input / output unit 21, an open / close recognition unit 22, an image processing unit 23, 24, a storage unit 25, and a communication unit 26.

  The input / output unit 21 is a function for inputting / outputting signals (information) to / from equipment or devices connected to the remote monitoring device 2. Here, for the sake of convenience, the position is assumed to realize transmission and reception of signals among the air conditioner 11, the camera 12, and the control device 3. The input / output unit 21 is actually a plurality of controllers for input / output, for example.

  The opening / closing recognition unit 22 is a function for recognizing opening / closing of the door of the car 1. By recognizing the opening / closing of the door, the opening / closing recognizing unit 22 determines the time required to open / close the door, that is, the time from when the door starts to open until the door closes (hereinafter referred to as “door opening time”). It is designed to keep time. This door opening time is one piece of information indicating the usage information of the elevator.

  The opening and closing of the door itself is realized by the control of the control device 3. From this, the opening / closing of the door can be recognized by a notification from the control device 3. The camera 12 performs still image shooting or moving image shooting in the car 1 at a predetermined time interval. From this, it is also possible to recognize the opening / closing of the door using image data output by the camera 12 by photographing.

  Here, for the sake of convenience, it is assumed that the control device 3 notifies that when the door is opened and closed, that is, when the door is opened, and when the opened door is closed. Assuming that, the open / close recognition unit 22 includes, for example, a CPU (Central Processing Unit) installed in the remote monitoring device 2, for example, an OS (Operating System) and one or more application programs (hereinafter abbreviated as “application”). It is realized by executing. Thereby, the open / close recognition unit 22 includes, as hardware, a CPU, a main storage device, a storage device storing an OS, and the like. The execution subject and the hardware configuration may be the same for the image processing unit 23 and the abnormality determination unit 24 described below.

  The image processing unit 23 has a function of performing image processing using image data output from the camera 12.

The image processing unit 23 includes a temperature recognition unit 23a and a passenger recognition unit 23b.
The temperature recognition unit 23a has a function of identifying and recognizing the temperature of the medium 13 as the temperature in the car 1 from the state of the medium 13 indicated by the image data. The technology described in Patent Document 1 can also be applied to the temperature recognition unit 23a.

  The passenger recognition unit 23b has a function of individually recognizing passengers getting on and off the car 1. In the present embodiment, the number of passengers in the car 1 is counted using the passenger recognition result. A well-known technique can be used for recognition of this passenger.

  The abnormality determination unit 24 has a function of determining the presence or absence of an abnormality in the air conditioner 11 using the recognition result by the open / close recognition unit 22 and the recognition result by the image processing unit 23.

  The storage unit 25 is one or more nonvolatile storage devices used for storing various types of information. The storage device is, for example, a hard disk device or a flash memory (here, including SSD (Solid State Drive) and the like).

  The communication unit 26 is a function for realizing communication via the network 5. Specifically, it is a communication device such as a NIC (Network Interface Controller).

  FIG. 2 is a diagram illustrating a configuration example of measurement result information and measurement result total information used for determining occurrence of abnormality by the air conditioner. Here, the measurement result information 210 and the measurement result aggregation information 220 will be described with reference to FIG.

  The measurement result information 210 is a set of information obtained at the time of one measurement. As shown in FIG. 2, the measurement result information 210 includes date information, door opening time information, door opening time information, passenger number information, temperature information, and condition determination information. The date information, door opening time information, door opening time information, number of passengers information, and condition determination information correspond to information indicating elevator usage information.

  The date information is information indicating the date of measurement. The door opening time information is information indicating the time when the door is opened. The door opening time information is information indicating the time when the door is open. “2016/8/1”, “6:12”, and “4 seconds” in FIG. 2 indicate that the door opened for 4 seconds from 6:12 on August 1, 2016. Actually, the door opening time information is information indicating a time of seconds or less.

The passenger number information is information indicating the number of passengers in the car 1 when the door is opened.
Here, the door application stores the number of passengers in the car 1 when opened as information. This is because the temperature in the car 1 is considered to depend on the number of passengers in the car 1.

  The temperature information is information indicating the temperature specified from the state of the imaged medium 13. The situation determination information is information indicating whether or not a predetermined condition is satisfied when the temperature is specified. “Satisfied” and “Unsatisfied” in FIG. 2 indicate that the condition is satisfied and the condition is not satisfied, respectively.

  As described above, in this embodiment, when the door is opened, the temperature is measured, that is, the temperature is specified from the state of the medium 13, and the specified result is measured together with the situation when the temperature is specified. The information 210 is saved. The opening of the door is triggered by the temperature measurement because the movement of the air inside the car 1 and the number of passengers in the car 1 (the heat source in the car 1) ) May change. That is, there is a possibility that the temperature in the car 1 may change greatly when the door is opened or closed.

  The case where the door does not open and close for a relatively long time is usually when there are no passengers. In that case, it can be expected that the temperature in the car 1 is the set temperature by the air conditioner 11 or a temperature in the vicinity thereof (temperature at equilibrium). Therefore, in the present embodiment, it is determined whether or not the condition is satisfied on the condition that the situation where the door does not open and close continues for a predetermined time. Thereby, the temperature measured in a situation where the condition is satisfied is regarded as the temperature in the car 1 when the air conditioner 11 performs temperature adjustment in an ideal situation.

  The measurement result total information 220 is information generated using the corresponding measurement result information 210. As shown in FIG. 2, the measurement result total information 220 includes date information, time zone information, average number of passengers information, door opening ratio information, set temperature information, minimum temperature information, maximum temperature information, average temperature information, corresponding Hour temperature information and determination result information. Among these, the minimum temperature information, the maximum temperature information, the average temperature information, and the corresponding temperature information correspond to the first information in the present embodiment. Moreover, date information, time zone information, average passenger number information, and door opening ratio information correspond to the second information in the present embodiment.

  In this embodiment, one day is divided into predetermined time zones, and the measurement result information 210 is tabulated for each time zone. The date / time information and the time zone information are information indicating the date / time and the time zone when the data was collected. “2016/8/1” and “6-7 o'clock” in FIG. 2 represent the time zone from 6-7 o'clock on August 1, 2016.

  The average number-of-passenger information is information indicating the average value of the number of passengers who have been on board when the car 1 is raised or lowered. The door open ratio information is information indicating the ratio of the door opened in a predetermined time zone as a percentage. In the present embodiment, the ratio is calculated by dividing the accumulated value of the time when the door is open by the time of the time zone and multiplying the result of division by 100 (ratio = accumulated). Value / time zone time x 100).

  The set temperature information is information indicating the temperature set as the target temperature in the air conditioner 11. The minimum temperature information is information indicating the minimum temperature among the temperatures indicated by the measurement result information 210. The maximum temperature information is information indicating the maximum temperature among the temperatures. The average temperature information is information indicating the average value of the temperature indicated by the measurement result information 210. In this embodiment, the average temperature is calculated by dividing the accumulated value of the temperature indicated by the measurement result information 210 by the number of the measurement result information (average temperature = accumulated value of temperature / measurement result). Number of information 210).

  The corresponding temperature information is information stored as measurement result information 210 when the predetermined condition is satisfied, that is, the condition determination information indicates “satisfied”. In the present embodiment, when there are a plurality of temperatures that satisfy the condition, the average value is stored as temperature information at the time.

  The temperature indicated by the relevant temperature information can be regarded as the temperature in the car 1 when the air conditioner 11 performs temperature adjustment in an ideal situation as described above. Therefore, in the present embodiment, when there is a temperature indicated by the corresponding temperature information (here, it is a temperature exceeding 0 degrees as will be described later), abnormality determination of the air conditioner 11 is performed using the temperature. I am doing so. By considering the usage information of the elevator and specifying the temperature to be used for abnormality determination, the abnormality determination of the air conditioner 11 can be performed with higher accuracy.

  Whether or not an abnormality has occurred in the air conditioner 11 is determined for each measurement result total information 220, that is, in units of time zones. This is because there is a possibility that the temperature indicated by the medium 13 or the temperature in the car 1 changes more than usual for some reason. For example, the passenger may touch the medium 13 or an object having a large temperature difference from the temperature in the car 1 may contact the medium 13. For this reason, in this embodiment, it is determined whether or not an abnormality has occurred in the air conditioner 11 in units of measurement result total information 220, that is, in units of time zones. By determining whether or not an abnormality in such a time zone has occurred, the presence or absence of an abnormality in the air conditioner 11 can be determined with higher accuracy.

  The measurement result information 210 is generated by the open / close recognition unit 22, and the generated measurement result information 210 is stored in the storage unit 25. On the other hand, the generation of the measurement result total information 220 is performed by the abnormality determination unit 24, and the generated measurement result total information 220 is also stored in the storage unit 25.

  The measurement result totaling information 220 as shown in FIG. 2 makes it possible to grasp the overall usage status when the elevator is used and the adjustment capability of the air conditioner 11 under the usage status. From this, when it is determined that an abnormality has occurred, the person in charge can confirm from the measurement result totaling information 220 whether or not an abnormality has occurred, the degree of the abnormality, and the like. Therefore, the measurement result totaling information 220 can be used as information for proposing replacement of the air conditioner 11 to a building user or the like.

  FIG. 3 is a flowchart illustrating an example of the temperature measurement process. This temperature measurement process is a process executed to acquire (generate) the measurement result information 210. As described above, the open / close recognition unit 22 is realized by executing this temperature measurement process, and the image processing unit 23 operates under the control of the open / close recognition unit 22. Next, the temperature measurement process will be described in detail with reference to FIG.

  As described above, temperature measurement is performed by opening the door. As a result, the temperature measurement process is executed in response to a notification from the control device 3 that the door is opened. The CPU that actually executes the application activated by the opportunity is the CPU, but the open / close recognition unit 22 corresponds to the functional configuration. Therefore, the description will be given assuming that the open / close recognition unit 22 is a main body that executes processing.

  First, the opening / closing recognition unit 22 generates date information and door opening time information from the current time, and starts timing to specify the door opening time (S301). The time is measured using a hardware timer mounted on the CPU, for example.

  Next, the open / close recognition unit 22 instructs the image processing unit 23 to start an image processing application, and specifies (recognizes) the temperature indicated by the state of the medium 13 using the image data input from the camera 12. The identification result is acquired (S302). Thereafter, the open / close recognition unit 22 instructs the image processing unit 23 to start another application for image processing, and recognizes passengers using the image data from the camera 12 (here, the number of passengers in the car 1). Are included) (S303).

  Next, the open / close recognition unit 22 determines whether or not the control device 3 has notified that the door has been closed (S304). When this is notified from the control device 3, the determination in S304 is YES and the process proceeds to S305. When the control device 3 does not notify that effect, the determination in S304 is NO and the process returns to S303. Thereby, the open / close recognition unit 22 causes the image processing unit 23 to recognize the passenger while the door is open, and acquires the number of recognized passengers from the image processing unit 23 by determining YES in S304. .

  In S305, the open / close recognition unit 22 determines whether a predetermined condition is satisfied, and generates condition determination information according to the determination result. The determination is made with reference to the measurement result information 210 stored immediately before, for example. Thereby, for example, when the time during which the door is closed before opening the door is equal to or longer than a predetermined time, it is determined that the condition is satisfied.

  The generation of the measurement result information 210 is completed by the generation of the condition determination information. From this, thereafter, the open / close recognition unit 22 stores the generated measurement result information 210 in the storage unit 25 (S306). After the storage, the temperature measurement process ends.

  As described above, the generation of the measurement result information 210 is realized by the open / close recognition unit 22 and the image processing unit 23. Therefore, the open / close recognition unit 22 and the passenger recognition unit 23b correspond to the situation recognition unit in the present embodiment.

  FIG. 4 is a flowchart illustrating an example of the aggregation / abnormality determination process. This aggregation / abnormality determination process is a process executed to generate the measurement result aggregation information 220 by aggregating the contents indicated by the stored measurement result information 210 and determining the presence or absence of abnormality from the aggregation result. is there. Next, an example of the totalization / abnormality determination process will be described with reference to FIG.

  As described above, the measurement result total information 220 is generated for each time zone. Thereby, the aggregation / abnormality determination process is a timer interrupt process that is executed as time passes. By executing the aggregation / abnormality determination process, the abnormality determination unit 24 is realized. For this reason, the abnormality determination unit 24 is assumed as a main body that executes the processing and will be described.

  First, the abnormality determination unit 24 acquires setting information indicating a set temperature set as a target temperature in the air conditioner 11 (S401). This setting information is information stored in the storage unit 25, for example. Next, the abnormality determination unit 24 substitutes 1 for the variable i and substitutes 0 for the variable k (S402). The variable i is a variable for counting the number of pieces of measurement result information 210 stored in the target time zone. The variable k is a variable for counting the number of pieces of measurement result information 210 whose condition determination information is “satisfied” in the measurement result information 210. In addition, 0 is also substituted into a variable jo described later in S402.

  Next, the abnormality determination unit 24 reads out one of the measurement result information 210 stored in the target time zone from the storage unit 25 and performs substitution into variables hj, dw, ho, mint, and maxt ( S403). Thereby, the number of passengers, the door opening time, and the temperature indicated by the read measurement result information 210 are assigned as initial values to the variables hj, dw, and ho, respectively. The temperature is also substituted as an initial value for variables mint and maxt. The measurement result information 210 stored in the target time zone is, for example, the measurement result information 210 in which the time indicated by the door opening time information is the time within the time zone.

  After the substitution, the abnormality determination unit 24 increments the value of the variable i (S404). Next, the abnormality determination unit 24 reads out the measurement result information 210 stored next to the measurement result information 210 read immediately before from the measurement result information 210 stored in the target time zone (S405). .

  After the reading, the abnormality determination unit 24 updates the values of the variables hj, dw, and ho (S406). Thereby, the variable hj is updated to a value obtained by adding the number of passengers indicated by the read measurement result information 210 to the previous value. The variable dw is updated to a value obtained by adding the door opening time indicated by the read measurement result information 210 to the previous value. The variable ho is updated to a value obtained by adding the temperature indicated by the read measurement result information 210 to the previous value.

  Next, the abnormality determination unit 24 determines whether or not the value of the variable mint is greater than the temperature indicated by the read measurement result information 210 (S407). When the temperature indicated by the read measurement result information 210 is the lowest temperature among the temperatures so far, the determination in S407 is YES, and after the temperature is substituted into the variable mint in S408, the process proceeds to S409. When the temperature indicated by the read measurement result information 210 is not the lowest temperature among the previous temperatures, the determination in S407 is NO and the process proceeds to S409.

  In S409, the abnormality determination unit 24 determines whether or not the value of the variable maxt is lower than the temperature indicated by the read measurement result information 210. When the temperature indicated by the read measurement result information 210 is the highest temperature among the temperatures so far, the determination in S409 is YES, and in S410, the temperature is substituted for the variable maxt, and then the process proceeds to S411. When the temperature indicated by the read measurement result information 210 is not the highest temperature so far, the determination in S409 is NO and the process proceeds to S411.

  In S411, the abnormality determination unit 24 determines whether or not the condition determination information in the read measurement result information 210 indicates “satisfied”. If the condition determination information indicates “satisfied”, the determination in S411 is YES, and the process proceeds to S413. If the condition determination information indicates “unsatisfied”, the determination in S411 is NO and the process proceeds to S412.

  In S412, the abnormality determination unit 24 increments the value of the variable k and updates the value of the variable jo to a value obtained by adding the temperature indicated by the read measurement result information 210 to the previous value. Thereafter, the process proceeds to S413.

  In S413, the abnormality determination unit 24 determines whether or not the processing of the measurement result information 210 stored in the target time zone has been completed. When all the measurement result information 210 stored in the target time zone is processed, the determination in S413 is YES, and the process proceeds to S414. If there is an unprocessed measurement result information 210 stored in the target time zone, the determination in S413 is NO and the process returns to S404.

  In S414, the abnormality determination unit 24 calculates the average number of passengers, the door opening ratio, and the average temperature using the values of the variables i, hj, dw, and ho. The average number of passengers is calculated by dividing the value of variable hj by the value of variable i. The door opening ratio is calculated by multiplying the value obtained by dividing the value of the variable dw by the value of the variable i by 100. The average temperature is calculated by dividing the value of the variable ho by the value of the variable i.

  In S415, the abnormality determination unit 24 calculates the corresponding temperature using the values of the variables jo and k. The calculation is performed by dividing the value of the variable jo by the value of the variable k.

  Next, the abnormality determination unit 24 performs an abnormality determination process for determining whether or not an abnormality has occurred in the air conditioner 11 in the target time zone (S416). For example, when there is a corresponding temperature, the temperature difference between the corresponding temperature and the set temperature is set as a threshold temperature difference (hereinafter referred to as “first”). This is done depending on whether or not If the temperature does not exist at the time, for example, the temperature closest to the set temperature is extracted from the minimum and maximum temperatures, and whether or not an abnormality has occurred using the temperature difference between the extracted temperature and the set temperature Judgment is made. Thereby, for example, whether the temperature difference between them is equal to or less than a temperature difference (hereinafter referred to as “second temperature difference”) set as a threshold separately from the first temperature difference is determined. . The magnitude relationship between the first temperature difference and the second temperature difference is second temperature difference ≧ first temperature difference.

  With this abnormality determination, generation of information included in the measurement result total information 220 ends. Therefore, next, the abnormality determination unit 24 stores the generated measurement result total information 220 in the storage unit 25.

  Next, the abnormality determination unit 24 determines whether or not the time period in which it is determined that an abnormality has occurred continues for a predetermined number of times N (N is an integer equal to or greater than 1) (S418). If the time period determined to be abnormal has been repeated N times including the target time period this time, the determination in S418 is YES and the process proceeds to S419. If the time zones are not continuous as described above, the determination in S418 is NO, and the aggregation / abnormality determination process ends here.

  In S419, the abnormality determination unit 24 issues a notification to notify the monitoring server 6 that an abnormality has occurred in the air conditioner 11 via the network 5. After the notification, the aggregation / abnormality determination process ends.

  This notification is performed by causing the communication unit 26 to transmit the information (signal) for the notification under the control of the abnormality determination unit 24. Therefore, the abnormality determination unit 24 corresponds to a notification control unit in the present embodiment.

  In the present embodiment, the measurement result information 210 is generated, and the measurement result total information 220 is generated in a form of totaling the contents. However, the measurement result total information 220 may be directly generated. . Information constituting the measurement result total information 220 and its contents are not particularly limited. For example, in the above embodiment, the temperature measurement is triggered by the opening of the door, but images are input from the camera 12 at a predetermined interval, and the image capturing timing of the image is the time since the door was last closed, The condition determination may be performed based on the number of passengers in the image. Also, it recognizes that a predetermined time has passed since the last closing, and that the number of passengers is less than or equal to the predetermined number (or 0), and the temperature is specified from the image of the camera 12 when the condition is satisfied. May be. In addition, it is possible to determine whether the temperature is set by the function of the air conditioner 11 using an image obtained when the door does not open and close for a relatively long time, and there are passengers in the car to some extent. In order to determine whether the temperature in the car at the time is within a predetermined range, the measurement result totaling information 220 may be generated using only images when the number of passengers is a predetermined number or more. By doing in this way, the temperature in a cage | basket under the arbitrary utilization conditions of an elevator can be calculated | required.

  Moreover, although the remote monitoring apparatus 2 performs abnormality determination of the air conditioner 11, the abnormality determination can be performed if it is an information processing apparatus which can acquire required information. For this reason, the remote monitoring device 2 does not have to be an information processing device installed in a building where an elevator is provided. For example, the monitoring server 6 may be used.

  For this reason as well, the present invention is not limited to the above-described embodiments or modifications, and various other modifications are possible. For example, the above-described embodiment has been described in detail for easy understanding of the present invention, and is not necessarily limited to the one having all the configurations described. Similarly, the operation is not limited. The functional configuration of the remote monitoring device 2 is not limited. The functional configuration to be mounted on the remote monitoring device 2 may be distributed to a plurality of information processing devices.
