Description

  The present invention relates to an elevator control system, and is suitable for application to, for example, an elevator control system that controls the operation of a car based on the number of people in the car.

  There is a car number measurement system that analyzes the video signal captured by a camera installed in the elevator car, determines the number of users, and measures the number of users. The car number measurement system sends a signal that measures the number of users in the car to the operation control unit, and also sends a signal that determines that the camera is abnormal when the capture of the video signal of the camera is delayed to the operation control unit. Send to. In this way, the operation control unit can detect the abnormality that has occurred in the camera by the signal transmitted from the in-car number counting system.

  However, if the car number measuring system in the car becomes abnormal, the signal of the abnormality generated in the camera is not transmitted to the operation control unit. In this case, there is a suspicion that an abnormality in the camera and an abnormality in the number of people counting process are suspected, but a worker is going to the site to restore the in-car number counting system.

  Here, as a technique for detecting an abnormality, when a signal indicating that a person is inside the car from the motion sensor is not input to the failure detection device, the load detection signal or the car presence signal is input before input. An elevator is known that compares the image signals of the latter and the latter and determines that the motion sensor is out of order if there is a difference between the two that makes it possible to regard a person in the car (Patent Document 1). reference).

JP 2012-184080 A

  In the technique described in Patent Document 1, when any one of the sensors related to the load detection signal, the car call presence signal, and the image signal is out of order, it is not possible to determine the failure of the motion sensor. Therefore, even if the technique described in Patent Document 1 is applied to the number-of-people counting system to determine the failure of the camera by the other device, there is a possibility that the other device is out of order. Cannot determine the failure. In other words, despite the situation in which it is suspected that there is an abnormality in the camera and an abnormality in the number of people counting process, that is, whether it is abnormal or not, it is still necessary for the worker to visit the site and take action. There's a problem.

  The present invention has been made in consideration of the above points, and it is an object of the present invention to propose an elevator control system that can reduce the situation in which a worker goes to the site and responds when an abnormality in the elevator control system is suspected. To do.

  In order to solve such a problem, in the present invention, from the sensor information indicating the state of the car collected by the sensor, the number of people counting the number of users who are in the car, and the number of people counting unit An output unit that outputs the number-of-people information to the operation control device that controls the operation of the car based on the number-of-people information that is measured by, and the number-of-people information that indicates the number of people measured by the number-of-people measurement unit is used. One or both of the number-of-people counting unit and the output unit based on judgment information indicating that a person does not satisfy the cycle characteristic that is a cycle in which the person gets in the car or a cycle in which the user does not get in the car. The recovery department that tries to recover the

  In the above configuration, for example, when the number of users in the car does not satisfy the periodic characteristic, the elevator control system is suspected to be abnormal, and one or both of the number-of-people counting unit and the output unit are attempted to be restored, thereby Can be expected to reduce the number of situations in which a person has to go to the site to deal with the situation.

  According to the present invention, a highly reliable elevator control system can be realized.

  Problems, configurations, and effects other than those described above will be clarified by the following description of the embodiments.

It is a figure which shows an example of the time chart of unmanned information by 1st Embodiment. It is a figure which shows an example of the flowchart which concerns on the abnormality detection corresponding process by 1st Embodiment.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In the present embodiment, a configuration will be mainly described in which a phenomenon in which the number of people measuring device is suspected is detected, the state of the number of people measuring device is diagnosed, and when the number of people measuring device is abnormal, an attempt is made to restore the number of people measuring device. To do.

  In the present embodiment, for example, from the number of users in the elevator car, it is determined that the cycle characteristic that is the cycle in which the user gets in the car or the cycle in which the user does not get in the car is satisfied. In this case, the state of the people counting apparatus is diagnosed, and if there is an abnormality in the people counting apparatus, an attempt is made to restore the people counting apparatus. Here, as a case where the user does not satisfy the cycle characteristic that is the cycle of getting on the car, it is possible that the number of people in the car does not reach the specified number of people (full capacity, above the specified boarding rate) for the specified time or longer. Be done. Further, as a case where the user does not satisfy the periodic characteristic that is a period in which the user does not get into the car, it can be mentioned that the car has become the specified number of people (unmanned (zero passengers)) for a predetermined time or longer.

  In this specification and the drawings, elements having substantially the same function or configuration are designated by the same reference numerals, and duplicate description will be omitted.

(1) First Embodiment In FIG. 1, 100 indicates an elevator system according to the first embodiment as a whole.

  FIG. 1 is a diagram illustrating an example of a configuration of the elevator system 100. The elevator system 100 includes a car 101, a rope 102, a hoist 103, and a counterweight 104.

  The car 101 is connected to a counterweight 104 via a rope 102. The rope 102 wound around the sheave is driven by the rotation of the sheave of the hoisting machine 103 which is supplied with power from a power source (not shown). Then, the relative position between the car 101 and the counterweight 104 changes, and the car 101 moves up and down the hoistway 105.

  The car 101 is provided with a sensor 111 and a car door 112.

  The sensor 111 is, for example, a camera that captures a user who rides in the car 101, is connected to an A/D (analog-to-digital) converter 130, which will be described later, and A/D-converts the captured video signal. To the container 130. The installation position of the sensor 111 is accommodated in the rear ceiling part of the car 101, the liquid crystal display on the front floor of the floor 101, etc., and the angle of view, focus, etc. are adjusted so that the user in the car 101 can be seen. There is. In the present embodiment, as the sensor 111, an existing camera installed in the car 101 is used, but these may be newly provided.

  Note that the sensor 111 will be described using a camera as an example, but the sensor 111 is not limited to the camera, and a sensor such as a load sensor that can measure the number of users in the car 101 can be appropriately employed. it can.

  The car door 112 engages with the car door 113 to open and close when the car 101 has landed on the car floor. At the landing floor, the car door 112 and the car door door 113 are opened so that the user can get in or out of the car 101.

  The elevator system 100 also includes a control panel 120, an A/D converter 130, and a person counting device 140.

  The control panel 120 includes an operation control device 121 and integrally controls the operation of the elevator system 100.

  The operation control device 121 controls the operation of the car 101 based on the number of people measured by the number-of-people measuring device 140 to improve the operation efficiency. For example, when there is no user in the car 101, the operation control device 121 performs control to close the car door 112 and the landing door 113 when they are open. Further, when the number of passengers is not full based on the load but is full based on the image, the car door 112 and the landing door 113 are closed immediately, and control for calling another car is performed.

  The operation control device 121 is, for example, a printed circuit board including a processor and a memory, and drives the hoisting machine 103, opens/closes the car door 112 and the landing door 113, transmits/receives information to/from the people counting device 140, and the like. ..

  The function of the operation control device 121 (a setting unit 221, a determination unit 222, etc. described later) may be realized by, for example, a processor reading a program into a memory and executing the program (software), or a hardware such as a dedicated circuit. It may be realized by hardware, or may be realized by combining software and hardware. Further, some of the functions of the operation control device 121 may be realized by another computer that can communicate with the operation control device 121.

  The A/D converter 130 receives an analog signal that is constantly transmitted from the sensor 111, converts the analog signal into a digital signal (for example, imaging data that is an example of sensor information), and transmits the digital signal to the person counting apparatus 140.

  The number-of-people counting device 140 measures the number of passengers in the car 101 based on the sensor information (for example, video data, load data) transmitted from the A/D converter 130.

  The number-of-people counting device 140 is, for example, a computer and includes a processor 141, a memory 142, an input device 143, an output device 144, and a communication device 145.

  The functions of the number-of-people counting device 140 (such as the number-of-people counting unit 211, the output unit 212, and the restoration unit 213 described below) may be realized by the processor 141 reading the program into the memory 142 and executing the program (software). , May be realized by hardware such as a dedicated circuit, or may be realized by combining software and hardware. For example, the number-of-people counting unit 211 may be realized by software, and the output unit 212 may be realized by hardware. Further, some of the functions of the people counting device 140 may be realized by another computer that can communicate with the people counting device 140. It should be noted that a part of the functions of the people counting device 140 is realized by software.

  Here, the first program related to the number-of-people counting unit 211 and the output unit 212 is stored in the first storage area of the memory 142 (for example, flash memory), and the second program related to the restoration unit 213 is stored in the memory 142. Is stored in a second storage area different from the first storage area. In this way, by separating the second program of the restoration unit 213 from the first program of the processing unit (the number of people counting unit 211 and the output unit 212) to be restored, the restoration unit 213 outputs the number of people counting unit 211 and the output. It becomes possible to attempt recovery of the unit 212 (for example, restart of the first program). In addition, if the restoration unit 213 is realized by hardware, the second program may not exist.

  The first program is stored in the first flash memory (an example of the first storage area), and the second program is stored in the second flash memory (second storage) different from the first flash memory. The configuration may be stored in an example of the area). Further, the first program may be stored in each of the first storage area (for example, the first flash memory) and the second storage area (for example, the second flash memory).

  In addition, the number-of-persons measuring device 140 may not be provided with the input device 143 and the output device 144. Although the number of people counting device 140 is shown as an example provided outside the control panel 120, it may be provided integrally within the control panel 120. Further, it is also possible to replace only the people counting device 140 or install a program capable of executing the processing of each part in the people counting device 140 into the existing people counting device 140 by updating the elevator system 100 or the like. Is.

  FIG. 2 is a diagram showing an example of an elevator control system (elevator control system 200).

  The elevator control system 200 includes a sensor 111, an operation control device 121, an A/D converter 130, and a person counting device 140.

  As described above, the sensor 111 captures an image of the user who gets on the car 101, and sends a video signal to the A/D converter 130 of the number-of-people counting device 140. Further, the A/D converter 130 takes in a video signal (analog signal) from the sensor 111, converts the video signal into video data (digital data), and transmits the video data to the people counting apparatus 140. The sensor 111 may be a network camera or the like. In this case, the A/D converter 130 may not be provided.

  The people counting device 140 includes a people counting unit 211, an output unit 212, and a restoration unit 213.

  The number-of-people counting unit 211 measures the number of users who are in the car 101 from the video data showing the state of the car 101 collected by the sensor 111. For example, the number-of-people counting unit 211 extracts characteristics of a person such as a head and a body from the video data transmitted from the A/D converter 130, determines the users in the car 101, and determines the number of users (use Number of people).

  The output unit 212 controls the operation of the car 101 based on the number-of-people information (may be a signal or data) indicating the number of people measured by the number-of-people counting unit 211. Output the number of people to. Note that the number-of-people information corresponding to the number of users in the car 101 indicates whether there are users in the car 101 (manned) or no users in the car 101 (unmanned). It may be the determined information.

  The restoration unit 213 tries to restore one or both of the number-of-people counting unit 211 and the output unit 212. For example, in the restoration unit 213, the number-of-people information indicating the number of people measured by the number-of-people counting unit 121 satisfies the cycle characteristic that is the cycle in which the user gets in the car 101 or the cycle in which the user does not get in the car 101. Recovery of one or both of the number-of-people counting unit 211 and the output unit 212 is attempted on the basis of the determination information indicating that there is none.

  More specifically, the restoration unit 213 confirms the operating states of the number-of-people counting unit 211 and the output unit 212 based on the request from the operation control device 121. In addition, for example, when the restoration unit 213 determines that one or both of the people counting unit 211 and the output unit 212 are not operating normally, the restoration unit 213 restarts the first program related to the people counting unit 211 and the output unit 212. To do. The recovery unit 213 stops the first program (first program that has hung up, entered an endless loop, or the like) that is running, and is different from the flash memory in which the first program is stored. The first program may be read from another flash memory and executed.

  The operation control device 121 includes a setting unit 221 and a determination unit 222.

The setting unit 221 has a specified time from the reception of the number-of-people information (unmanned information or congestion information) for detecting the cycle characteristic information indicating the cycle characteristics until the reception of the number-of-people information for detecting the next cycle characteristic information. Set T ₀ . The unmanned information is the number of people information indicating that there are no users in the car 101. The congestion information is the number-of-people information indicating that there are a predetermined number of users or more in the car 101. Below, the case where the number-of-people information for detecting the periodic characteristic information is unmanned information will be mainly described as an example.

The setting unit 221 sets the specified time T ₀ according to an instruction (operation) from the system administrator, the maintenance person, or the administrator, for example, at the time of initial setting of the operation control device 121 or at the time of maintenance and inspection. At this time, depending on the installation environment of the elevator (for example, the tenant), a plurality of options (9:00 to 17:00 in the case of a bank, 10:00 to 20:00 in the case of a supermarket, etc.) are provided in advance so that they can be selected. Good.

  The determination unit 222 determines whether the number-of-people information transmitted from the number-of-people counting device 140 is unmanned information. For example, if it is determined from the number-of-people information indicating the number of people measured by the number-of-people counting unit 211 whether there is a user in the car 101 and it is determined that there is no user in the car 101, the next car The time until it is determined that there is no user in 101 is counted, and the result that it is determined that the counted time exceeds the time showing the periodic characteristic that is the period in which the user does not get in the car 101 is generated as the determination information. To do.

  Further, for example, the determination unit 222 determines whether or not there is a user in the car 101 based on the number of people information indicating the number of people measured by the number of people measurement unit 211, and determines that there is a user in the car 101. If it is, it is determined whether or not there is congestion indicating that the measured number of people is greater than or equal to a predetermined number, and when it is determined that it is congested, the time until the next congestion is determined is counted and counted. The determination result may be generated as a result of the determination that the time exceeds the time indicating the cycle characteristic that is the cycle in which the user gets on the car 101.

  Then, the determination unit 222 determines whether or not it is possible to communicate with the number-of-people counting device 140, and if it is possible to determine, it is determined whether or not the number-of-people counting unit 211 is operating normally, and it operates normally. When it is determined that it is not, the generated determination information is transmitted to the restoration unit 213. In addition, the determination unit 222 determines whether or not the number-of-people counting unit 211 is operating normally after transmitting the generated determination information to the restoration unit 213, and when determining that the number of people counting unit 211 is not operating normally, the number of people counting is determined. The monitoring room may be notified that the device 140 is defective.

  Further, the determination unit 222 determines whether or not it is possible to communicate with the number-of-persons measuring device 140, and if it is possible to determine, it is determined whether or not the number-of-persons measuring unit 211 and the output unit 212 are operating normally, When it is determined that one or both of the number-of-persons counting unit 211 and the output unit 212 are not operating normally, the determination information generated from the number of persons transmitted from the output unit 212 may be transmitted to the restoration unit 213. In this case, the determination unit 222, after transmitting the generated determination information to the restoration unit 213, determines whether the number-of-people counting unit 211 and the output unit 212 are operating normally, and determines that they are not operating normally. At this time, the fact that the number of people measuring device 140 is defective may be reported to the monitoring room.

More specifically, when the determination unit 222 determines that the unattended information is the unattended information, the determination unit 222 counts (counts) the elapsed time T indicating the time elapsed until the next unattended information is received. At this time, if the elapsed time T until the next unmanned information is received is equal to or longer than the specified time T ₀ (T≧T ₀ ), an instruction for recovery is transmitted to the number-of-people counting device 140. By such an instruction, the operating state of the people counting device 140 is diagnosed. When the determination unit 222 determines that the number-of-people counting unit 211 or the output unit 212 is abnormal, the determination unit 222 attempts to restore the number-of-people counting unit 211 and the output unit 212. When the program for realizing the number-of-people counting unit 211 and the program for realizing the output unit 212 are different programs, the determination unit 222 stores information about the processing unit that is not operating normally ( The configuration may be such that the failure information) is included in the determination information and the recovery of the processing unit that detected the abnormality is attempted.

  2 shows the configuration in which the operation control device 121 includes the setting unit 221 and the determination unit 222, each of the setting unit 221 and the determination unit 222 has a configuration independent of the operation control device 121 (by another computer. Realized configuration).

  Further, the elevator control system is not limited to the configuration of the elevator control system 200 described above. For example, the elevator control system may not include the sensor 111, the sensor 111 and the A/D converter 130 may not be included, and the operation control device 121 may not be included. Alternatively, the function of the operation control device 121 and the function of the number of people counting device 140 may be realized by one device, or other configurations may be included.

  Next, a method of detecting a suspicion of an abnormality in the number-of-people counting device 140 using unmanned information will be described.

  FIG. 3 is a diagram showing an example of a time chart of unattended information.

  In the operation of elevators, no matter how often the elevators are operated, for example, when 24 hours a day, the number of people in the car 101 becomes unattended (zero passengers) in a predetermined time zone. You can At this time, the people counting device 140 transmits the unmanned information to the operation control device 121. On the next day, when the inside of the car 101 becomes unmanned again in a predetermined time zone, the number-of-people counting device 140 again transmits unmanned information to the operation control device 121.

Here, the time interval of the timing of receiving the second unmanned information from the timing of receiving the first unmanned information is T ₁ , and the time of the timing of receiving the N+1th unmanned information from the timing of receiving the Nth unmanned information. The interval is T _N (N is a positive integer), and the reception interval of the unmanned information detected by the operation control device 121 is the specified time T ₀ (periodic characteristic).

For example, when the specified time T ₀ is set to 24 hours in an elevator that operates 24 hours a day, it is assumed that the time in which the inside of the car 101 is unmanned is less than 24 hours. At this time, if some abnormality occurs in the number-of-people counting device 140 and the transmission of information to the operation control device 121 is interrupted, the unmanned information itself is not transmitted. Therefore, if the unmanned information for the third time is to be received, it takes 24 hours. After the lapse of time, T ₃ ≧T ₀ . The operation control device 121 counts the elapsed time T indicating the time elapsed after receiving the unmanned information, and determines that there is a suspicion of some abnormality in the number-of-people counting device 140 at the time 301 when T ₃ ≧T _0. Then, the operation control device 121 transmits an instruction for restoration, and the diagnosis of the number-of-persons measuring device 140, the restoration process of the number-of-persons measuring device 140, and the like are performed.

  The same applies to the congestion information regarding the above-mentioned contents. That is, in the operation of the elevator, for example, in an elevator installed in an office building, when the number of people in the car 101 is full (more than a predetermined number of people) in 24 hours a day, it is in a predetermined time zone (in the morning). Time zone, daytime zone, etc.). At this time, the people counting device 140 transmits the congestion information to the operation control device 121. When the inside of the car 101 becomes crowded again in the predetermined time zone on the next day, the number-of-people counting device 140 again transmits the crowding information to the operation control device 121.

  Next, a process of detecting an abnormality of the number-of-people counting device 140 using unmanned information and attempting to recover the number-of-people counting unit 211 and/or the output unit 212 as necessary will be described.

  FIG. 4 is a diagram showing an example of a flowchart of the abnormality detection handling process performed by the determination unit 222.

  First, when the determination unit 222 receives the number-of-people information indicating the number of users from the number-of-people measurement device 140, the determination unit 222 determines whether the number-of-people information is unmanned information (step S401). If it is determined that the information is unattended information, the determination unit 222 moves the process to step S402, and if it is determined that the information is not unattended, the determination unit 222 moves the process to step S403.

  In step S402, the determination unit 222 initializes the elapsed time T indicating the time elapsed from the reception of the unmanned information to the reception of the next unmanned information (eg, may be set to “0 seconds”). , You may set the current time.)

  In step S403, the determination unit 222 counts (updates) the elapsed time T.

  Note that in steps S401 to S403, the determination unit 222 counts the elapsed time T from the timing of receiving unattended information to the reception of the next unattended information. In this respect, the same applies to the congestion information, and in steps S401 to S403, the determination unit 222 counts the elapsed time T from the timing of receiving the congestion information to the reception of the next congestion information.

In step S404, the determination unit 222 determines whether the elapsed time T is the specified time T ₀ or more. Determination unit 222, when it is determined that the prescribed time _{T 0} or more, the process proceeds to step S405, if it is determined not the prescribed time _{T 0} or more, the process proceeds to step S401.

  In step S405, the determination unit 222 transmits an instruction regarding diagnosis to the person counting apparatus 140. For example, the determination unit 222 gives an instruction for confirming whether the people counting apparatus 140 is operating (for example, a PING (Packet Internet Groper) command for checking whether the people counting apparatus 140 is connected or not). Send. Further, for example, the determination unit 222 gives an instruction for confirming whether or not a malfunction has occurred in the number-of-people counting unit 211 and the output unit 212 (a predetermined request to the number-of-people counting unit 211 and the output unit 212, a hang-up, an infinite loop). (For example, request for diagnosis).

  In step S406, the determination unit 222 determines whether or not there is a response from the number-of-people counting device 140. When determining that there is a response, the determining unit 222 moves the process to step S407, and when determining that there is no response, moves the process to step S410.

  In step S407, the determination unit 222 determines whether or not there is a response from the number-of-people counting unit 211 and the output unit 212. When the determination unit 222 determines that there is a response, the exception is a situation in which the user did not use the car 101 during a predetermined time period, even though the number-of-people counting device 140 is operating normally. Since it has occurred suddenly, it is determined that the countermeasure (restoration processing) is unnecessary, and the abnormality detection countermeasure processing is ended. In addition, it is possible to avoid a situation where the people counting apparatus 140 is temporarily stopped by performing the restoration process in a situation where the people counting apparatus 140 is operating normally. On the other hand, when the determination unit 222 determines that there is no response, it determines that there is a high possibility that the software of the number-of-persons counting device 140 is defective, and moves the process to step S408.

  In step S<b>408, the determination unit 222 transmits a restoration instruction (an example of determination information) to the people counting device 140. For example, the determination unit 222 sends an instruction to the restoration unit 213 to perform restoration processing, and confirms whether or not a malfunction has occurred in the number-of-people counting unit 211 and the output unit 212 after a predetermined time has elapsed. The instruction is transmitted to the number-of-people counting unit 211 and the output unit 212.

  Here, in the number-of-people counting device 140, the restoration unit 213 restarts the first program related to the number-of-people counting unit 211 and the output unit 212 when receiving the instruction (judgment information) related to the restoration. For example, the processor 141 of the number-of-people counting device 140 executes the first program stored in the first storage area to implement the number-of-people counting unit 211, and the processor 141 is different from the first storage area in the second storage area. When the restoration unit 213 is realized by executing the second program stored in the storage area of the storage unit, the restoration unit 213 stores the storage unit in the first storage area based on the determination information transmitted from the determination unit 222. Restart the first program that is being executed. Further, for example, the processor 141 of the number-of-people counting device 140 executes the first program stored in the first storage area to realize the number-of-people counting unit 211 and the output unit 212, and the processor 141 stores the first memory. When the restoration unit 213 is realized by executing the second program stored in the second storage area different from the area, the restoration unit 213, based on the judgment information transmitted from the judgment unit 222, The first program stored in the first storage area may be restarted.
