Description

  The present invention relates to an elevator crime prevention system installed in a building such as an apartment, and more particularly to an elevator crime prevention system that prevents a user from getting on a suspicious person when getting into an elevator at a hall. .

  For example, in a building such as a condominium, especially when a resident who goes home at midnight gets on the elevator car, there is a possibility that a suspicious person will suddenly get in together and work as a robber or violence in the car. Under such circumstances, security measures against suspicious persons are strongly demanded.

  Here, as security measures, for example, a user is identified by installing a surveillance camera to monitor the state of the car or entering a personal identification code, and one user per elevator operation. There is a method to regulate so that it can only be placed.

  However, the above-described method using a surveillance camera requires a human to constantly monitor the video of the surveillance camera, and because the purpose is surveillance, it is possible to prevent a crime from actually occurring in the car. There are problems such as being unable to do so.

  On the other hand, in the driving limited to one user, the driving efficiency is very poor because it has to be carried many times when many users are waiting at the landing. There is a problem of spending. In addition, even if driving is limited to one user, there is a problem that a suspicious person is hidden at the landing and cannot be handled when the user gets in when the user gets in.

Conventionally, in order to solve such problems, the number of passengers is registered at the landing, and after the elevator car arrives, the number of passengers in the elevator is detected, and the number of passengers and the landing are in advance. A method is considered in which the elevator is operated only when the number of passengers registered matches the number of passengers registered (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 7-237837

  The crime prevention system disclosed in the above-mentioned Patent Document 1 judges the intrusion of a suspicious person based on the mismatch of the number of passengers by comparing and verifying the number of passengers registered in advance at the hall and the number of passengers in the car. It is.

  However, in such a method of detecting the presence or absence of a suspicious person by comparing the number of passengers, there is a problem that it is necessary to accurately determine the number of people who actually get on the car, and it is difficult to determine the number.

  In this case, Patent Document 1 discloses two methods, a method of determining the number of passengers using a camera image and a method of determining the number of passengers from a car load. However, in the method using a camera image, for example, a small child When a parent / child with a car comes on board and cannot be properly captured by the surveillance camera because the child is hidden by the parent, the number of passengers may not be counted. Further, in the method using the car load, for example, when a user gets on a heavy load, the load may be counted as the number of passengers.

  As described above, the number of passengers calculated from the camera image and the car load often differs from the actual number of passengers, and therefore it is impossible to accurately detect the intrusion of a suspicious person.

  The present invention has been made in view of the above points, and can carry a large number of users at the same time, and at that time, intrusion of a suspicious person can be accurately detected to ensure the safety of the user. An object of the present invention is to provide an elevator crime prevention system capable of ensuring the above.

  The elevator crime prevention system according to the present invention includes a registration means for registering load values of a plurality of users waiting at an elevator hall in a memory, and each user gets on the car upon arrival of the car. A load detection means for detecting the load value after the load, and a load value registered in the memory by the registration means by adding a predetermined error to the load value after boarding the user detected by the load detection means, Based on the comparison result of the load comparison means and the comparison result of the load comparison means, the operation of the car is controlled, and a value obtained by adding a predetermined error to the load value after the user rides is stored in the memory. When the load value is less than or equal to the registered load value, it is determined that no suspicious person has entered the vehicle and the car is operated, and a value obtained by adding a predetermined error to the load value after the user gets on the vehicle is registered in the memory. Was If it exceeds the load value, it is determined that there is a suspicious person entering configured by comprising a driving control means for stopping the operation by door open the cab.

  According to such a configuration, a value obtained by adding a predetermined error taking into account the weight of the baggage, for example, to the load value after each user actually boarded upon arrival of the car and pre-registered in the memory at the landing The load value of each user is compared, and the operation of the car is controlled based on the comparison result. In this case, if the value obtained by adding a predetermined error to the load value after boarding the user is equal to or less than the pre-registered load value, it is determined that no suspicious person has entered, and the car is operated. On the other hand, if the value after adding a predetermined error to the load value after boarding the user exceeds the pre-registered load value, it is determined that a suspicious person has entered and the car is opened and the operation is stopped. The

  As a result, it is possible to detect the intrusion of a suspicious person while carrying a plurality of users waiting at the landing at once, and when there is an intrusion of a suspicious person, the operation is immediately stopped with the door open. By doing so, crimes can be prevented and the safety of users can be ensured.

  Further, the present invention provides an elevator crime prevention system having the above-described configuration, comprising a load sensor installed on the floor surface of the landing, and the registration means is configured to receive the load sensor until the car arrives at the landing. The load value of each user detected by the above is registered in a memory.

  According to such a configuration, each user can register each load value in the memory simply by getting on the load sensor installed on the floor of the hall.

  The present invention further includes a load input device for inputting a load value by a button operation in the elevator crime prevention system configured as described above, wherein the registration means is configured to input the load until the car arrives at the landing. The load value of each user input by the apparatus is registered in a memory.

  According to such a configuration, each user can register each load value in the memory by inputting the load value through the load input device.

  Further, the present invention is an elevator crime prevention system configured as described above, and includes an authentication card that is distributed in advance to each user and records at least the load value of the user, and a card reader that reads information on the authentication card. The registration means registers in the memory the load value of the authentication card read for each user by the card reader until the car arrives at the landing.

  According to such a configuration, each user can register each load value in the memory by causing the card reader to read the information of the authentication card possessed by each user.

  In the elevator crime prevention system having the above-described configuration, the load registration start message is displayed until the car arrives at the landing, and the load registration is performed after the car arrives at the landing. It further comprises display means for displaying an end message.

  According to such a configuration, each user can perform load registration according to a load registration start message and a load registration end message displayed on the landing.

  According to the present invention, it is possible to carry a plurality of users waiting at the landing at a time, and by comparing the load value pre-registered at the landing with the load value after the user gets on the suspicious person's By accurately detecting the intrusion and controlling the operation of the car, crimes by suspicious persons in the car can be prevented and the safety of the user can be ensured.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing a configuration of a hall in an elevator crime prevention system according to an embodiment of the present invention.

  In the figure, 10 is an elevator hall, and 11 is a hold door installed at the elevator hall 10. Reference numeral 12 denotes a hall call button installed in the vicinity of the hold door 11. The hall call button 12 includes destination direction designation buttons 12a and 12b in the upward direction and the downward direction. The hall call button 12 also serves as a user load registration button as will be described later.

  Here, in this embodiment, a small load sensor 13 is embedded in the floor surface 10 a of the hall 10. The load sensor 13 detects the weight of the user as a load value when the user rides on the car 31 (see FIG. 4) when the user rides on the sensor surface before the hold door 11 as shown in the figure. It has possible functions. The user's load value detected by the load sensor 13 is registered in a storage unit 25 (see FIG. 2) described later.

  In addition, a display device 14 including, for example, a color liquid crystal monitor is installed in the vicinity of the hold door 11 of the hall 10. In addition to displaying various messages such as arrival notification of the car 31, the display device 14 displays messages relating to load registration as shown in FIGS.

  FIG. 2 shows an example of a load registration start message, which is displayed before the car 31 arrives. While the registration start message is displayed, the load can be registered, and the user standing by at the landing 10 presses the hall call button 12 and then gets on the load sensor 13 to load his own load ( (Weight) is registered.

  At this time, if the user has a baggage, the user gets on the load sensor 13 while holding the baggage so that the user gets the full weight including the weight of the baggage into the car 31. It shall be measured as a load value at the time.

  FIG. 3 shows an example of a load registration end message, which is displayed after the car 31 arrives. When this registration end message is displayed, the load registration is completed, and even if the user gets on the load sensor 13, the load is not registered.

  Next, the configuration of an elevator crime prevention system will be described.

  FIG. 4 is a block diagram showing a functional configuration of the elevator crime prevention system, which includes an elevator control device 21 in addition to the hall call button 12, the load sensor 13, and the display device 14 installed in the hall 10 described above.

  The elevator control device 21 is installed in a predetermined place such as a machine room of a building, for example. The elevator control device 21 is a computer that performs operation control of the entire elevator including group management control. Here, the display control unit 22, the call registration unit 23, the load registration unit 24, the storage unit 25, and the operation control unit 26 are provided. I have.

  The display control unit 22 performs message display control on the display device 14. The call registration unit 23 registers a call signal by operating the hall call button 12. The load registration unit 24 stores the load value of the user detected by the load sensor 13 in the storage unit 25 for each operation of the hall call button 12. The memory | storage part 25 consists of RAM etc., for example, and memorize | stores the load value of each user.

  The operation control unit 26 includes a microprocessor and controls the operation of the car 31. The operation control unit 26 performs various processes related to load registration through the display control unit 22 in addition to performing a process of causing the car 31 to respond to the hall 10 where the call is made in response to a call signal registered in the call registration unit 23. Processing for displaying a message on the display device 14, and comparing and verifying the load of each user registered in advance in the storage unit 25 by the load registration unit 24 and the load of each user actually on the car 31 The process and the process of executing or stopping the operation of the car 31 are performed according to the comparison verification result.

  On the other hand, the car 31 is provided with a door 32 and an operation panel 33 on the front thereof. The door 32 is opened and closed by driving a door motor (not shown). The operation panel 33 includes a destination floor button, a door open / close button, and the like.

  A load sensor 34 for detecting a car load is installed at the bottom of the car 31. A signal indicating the car load detected by the load sensor 34 is transferred to the operation control unit 26, and the operation control unit 26 calculates the load value of each user of the current car 31 based on the car load signal.

  Hereinafter, the processing operation in the crime prevention system of the elevator having such a configuration will be described in detail.

  FIG. 5 is a flowchart showing the processing operation of this system in the embodiment. In addition, each process shown by this flowchart is performed when the operation control part 26 in the elevator control apparatus 21 reads a program.

  Now, for example, a case will be described where a plurality of (five people) users go to the target floor from the entrance hall of the apartment. A load sensor 13 is installed at the elevator hall 10 in the entrance hall as shown in FIG.

  First, the five users who have come to the landing 10 press the hall call button 12 one by one and get on the load sensor 13 to perform load registration. At that time, as the hall call button 12 is pressed, a registration start message such as “Start registration. Please get on the load sensor” is displayed through the display control unit 22 as shown in FIG. It is displayed on the device 14 (step S11). This registration start message is displayed on the display device 14 until the car 31 arrives at the hall 10 in response to a call signal generated when the hall call button 12 is pressed.

  When the user gets on the load sensor 13 with the registration start message displayed, the load sensor 13 detects the load value of the user including the weight of the baggage held by the user. The loaded value is registered in the storage unit 25 by the load registration unit 24 (step S12).

  This load registration can be performed every time the hall call button 12 is operated while the registration start message is displayed, that is, until the car 31 arrives at the landing 10. Here, since it is assumed that five users are at the landing 10, the five users each press the hall call button 12 as described above and then get on the load sensor 13. Load registration will be performed. The total value of the loads of each user registered at this time is defined as Gm1.

  Here, the load registration is performed for each user. However, for example, by widening the sensor surface of the load sensor 13, a plurality of users get on the sensor surface together to register the load. A configuration in which only one operation is required is also possible.

  When the car 31 arrives at the landing 10 (Yes in Step S13), as shown in FIG. 3, for example, a registration completion message such as “Elevator has arrived. Registration is terminated.” Is displayed through the display control unit 22. It is displayed on the display device 14 (step S14). When this registration end message is displayed, the load registration is completed, and even if someone comes later and rides on the load sensor 13, the corresponding load is not registered.

  The fact that the car 31 has arrived at the landing 10 is turned on when, for example, a micro switch attached to the car 31 passes through a landing plate (landing detection plate) installed near the landing 10. To detect.

  After displaying the registration end message, the operation control unit 26 inputs the car load signal from the load sensor 34 installed at the bottom of the car 31 and checks the current car load value (step S15). The reason for checking the current car load value is to consider the case where another user has already boarded the car 31. The value of the car load at the time of arrival (the load in the car 31) is Gm2.

  Here, since the entrance hall of the apartment is assumed, even if other users are in the car 31 arriving at the hall 10, all the users must always get off at the entrance hall 31 Is once empty, the process of step S15 is not necessary.

  Next, the driving control unit 26 opens the door 32 of the car 31 and causes each user waiting at the landing 10 to get on (step S16). In consideration of the fact that some of the other users get off at the landing 10 when the door 32 is opened, it is preferable to check the car load value Gm2 at this point.

  After the door is opened, the operation control unit 26 detects the value of the car load after the user gets on the basis of the car load signal from the load sensor 34 (step S17). The value of the car load after this user boarding is set to Gm3.

  Here, the operation control unit 26 reads the total load value Gm1 of each user registered in advance in the storage unit 25, and the car load value at the time of arrival from the car load value Gm3 after the user gets on the vehicle. A value obtained by subtracting Gm2 (Gm3-Gm2) is obtained as a total value Gm4 of the loads of the users who actually get on, and the load values of both are compared and verified (step S18).

  As a result, if the total value Gm4 is less than or equal to the pre-registered total load value Gm1 of each user plus a predetermined error α, the operation control unit 26 determines that no suspicious person has entered. Then (Yes in step S19), the door 32 is closed, and then the operation to the destination floor registered by the operation of the operation panel 33 in the car 31 is executed (step S20). The reason why the error α is added is that the actual load value may be slightly different depending on, for example, baggage.

  On the other hand, when the total value Gm4 exceeds the pre-registered total load value Gm1 of each user plus a predetermined error α, the operation control unit 26 determines that a suspicious person has entered. (No in step S19), the operation of the car 31 is stopped with the door 32 opened (step S20).

  More specifically, it is assumed that the total value Gm1 of loads of five users registered in advance at the hall 10 is 300 [kg]. When the error α is 5%, if the total load value Gm4 of each user actually boarding is 300 + 15 = 315 [kg] or less, it is determined that no suspicious person has entered, and the car 31 Is operated as usual.

  The reason why the judgment criterion for the intrusion by the suspicious person is not “Gm1 + α” but “Gm1 + α” or less is that some of the users may not get on the car 31 for some reason.

  On the other hand, if the total value Gm4 of the load of each user actually boarding exceeds “Gm1 + α”, that is, if it is heavier than 315 [kg], the suspicious person suddenly enters and the load is increased. It is judged that it has increased. In this case, the car 31 is not operated, and is stopped with the door open. At that time, for example, an alarm may be automatically sounded or a measure such as automatically contacting the monitoring room may be taken.

  In this way, the load value of each user registered in advance at the landing 10 is compared with the load value (including the error) after each user actually gets on board when the car 31 arrives. If the load value after boarding the passenger exceeds the pre-registered load value, the car 31 stops in the door open state, so even if a suspicious person suddenly gets in, the crime can be prevented in advance. .

  In this case, in this system, the load value registered in advance and the load value after boarding the user are compared and the loads are compared as they are, so the number of passengers is calculated from the camera image and the car load as in the conventional method. Such processing is unnecessary, and the intrusion of a suspicious person can be accurately detected based on the result of the load comparison.

  Furthermore, in this system, not only one person but also a plurality of users can be carried at one time, so that driving efficiency is good and each user waiting at the hall 10 is not inconvenienced.

  In the above embodiment, as shown in FIG. 1, the load registration is performed by the user getting on the load sensor 13 at the landing 10, but the method shown in FIGS. 6 and 7 is used. May be used.

  FIG. 6 is a diagram showing load registration as another embodiment of the present invention, and shows a method of registering by operating the load input device 41.

  The load input device 41 is installed in the vicinity of the hold door 11 of the hall 10. The load input device 41 is provided with a number of numerical value buttons 42 for inputting load values. The user depresses these numerical buttons 42 and inputs his / her own load (weight). In this case, if there is a baggage, the weight of the baggage is added and input. The input load value is displayed on the display 43. When the registration button 44 is pressed in this state, the load value is registered in the storage unit 25.

  FIG. 7 is a diagram showing load registration as another embodiment of the present invention, and shows a method of registering using the authentication card 51.

  The authentication card 51 is composed of, for example, an IC card or a magnetic card, and is distributed in advance to a person (resident) who is permitted to use the elevator in advance. This authentication card 51 records its own load value (weight) in addition to information such as the user's name and destination floor. On the other hand, a card reader 52 for reading information on the authentication card 51 is installed in the vicinity of the hold area 11 of the hall 10. The user inserts his / her authentication card 51 into the card insertion slot 53 of the card reader 52.

  Thereby, when each information of the authentication card 51 is read and it is authenticated that the user is authorized, the load value (weight) of the user recorded therein is stored in the storage unit 25. Automatically registered. In some cases, the user may have a package. In this case, the user operates the operation unit 54 to additionally register the weight of the package. Further, when the user is accompanied by a friend or the like, the load value for the user is additionally registered through the operation unit 54.

  Although not particularly illustrated, authentication may be performed based on a user's fingerprint pattern using a fingerprint authentication device. However, the load value of the user needs to be registered in advance in the authentication database system, and the system searches for the load value corresponding to the user from the database and registers it in the storage unit 25. Become.

  The above-described method using an authentication card or fingerprint is for an elevator that also has an authentication system. If such an authentication system is used in combination, the security level can be further increased and the intrusion of a suspicious person can be prevented more reliably. it can.
