Description

  The present invention relates to an elevator control system having a security function.

  There are multiple residents or tenant staff in apartment buildings or multi-tenant buildings, and residents or tenant staff are not necessarily familiar with each other. It is difficult to distinguish. Therefore, recently, security systems for eliminating suspicious persons have been adopted in many buildings. An elevator is installed in many apartment buildings or multi-use buildings, and many elevator control systems equipped with a security function are constructed to improve the crime prevention effect (see, for example, Patent Document 1).

  There are various forms of this type of system. For example, as a first form, a key reading means is installed at a hall on the entrance floor of a building so that a person who wants to use the elevator cannot use the elevator at all without receiving authentication of the key possessed by the person. There is a system. Further, as a second form, a key reading means is installed in the car, and a person who wants to go to a specific floor of the building cannot make a car call without receiving authentication of the key he possesses. There is a system that makes it possible for anyone on the general floor other than the specific floor to freely use the elevator.

  The system of the first form is often adopted in a building for an apartment house and can obtain a high security function, but has a disadvantage that it is inconvenient for those who do not have a key.

On the other hand, the system of the second form is often employed in a relatively small residential building or the like in which one tenant occupies one floor. And according to the system of the 2nd form, the security function required for the tenant occupying the specific floor can be secured, while those who do not have the key do not need to go to the specific floor Therefore, it is possible to prevent inconvenience for these persons.
Japanese Patent Laid-Open No. 2005-22821

  As described above, the elevator control system according to the second embodiment applies the security function only to the specific floor and does not restrict the use of the elevator to other general floors. This is a system that satisfies the requirements of both residents and other general users.

  However, when a resident on a specific floor gets into the car from the entrance floor and obtains the key authentication and then goes to the specific floor after registering the car call, a third party gets into the car later. May come. And if a cage | basket | car reaches | attains a specific floor as it is, since the third party can also easily enter a specific floor following the resident of a specific floor, it will be in the state where required security is not ensured.

  In this case, if a resident on a specific floor requests that a third party who has boarded later to get out of the cage and there is no problem if the third party obeys the request gently, They usually feel psychological resistance to making such requests. In particular, it is thought that it is inevitable that a physically weak person such as a woman or an elderly person will ask an unknown third party to leave the car during an unpopular time such as midnight. .

  The present invention has been made in view of the above circumstances, and when a third party gets into the car following an elevator user who wants to go to a specific floor, the third party is excluded and necessary. It aims at providing the elevator control system which can ensure a security function.

  As means for solving the above-mentioned problems, the invention according to claim 1 is characterized in that key reading means provided in an elevator car for reading key information assigned to a key possessed by an elevator user, and said key reading means Key authentication means for authenticating the key based on the read key information, passenger number detection means for detecting the number of persons in the elevator car provided in the elevator car, and operation of a car call button in the elevator car And there is a car call based on the key number, and the destination floor related to the car call is a specific floor that can be used only by an elevator user who has been authenticated by the key. The number of passengers detected by the passenger number detection means is compared, and a third party other than the elevator user who has received key authentication is in the car. And a call registration processing means for rejecting the car call registration based on the car call, and an operation control means for operating the elevator based on the processing result of the call registration processing means. .

  According to a second aspect of the present invention, in the first aspect of the invention, when the call registration processing means rejects the car call registration, the third party riding in the car is out of the elevator car. It is characterized by comprising an informing means for informing at least one of whether to get off the vehicle or to receive key authentication.

  The invention according to claim 3 is the invention according to claim 1 or 2, wherein the passenger number detecting means is a load detector for detecting a load in an elevator car, and the call registration processing means is included in the key information. By comparing the weight data of the elevator user included and the detected load data from the load detector, it is determined whether or not the third party is in the car. Features.

  According to a fourth aspect of the present invention, in the invention of the third aspect, the call registration processing means is configured such that the detected load data is larger than a value obtained by adding a weight corresponding to baggage to weight data of an elevator user. The third party is determined to be in the car.

  According to a fifth aspect of the present invention, in the third or fourth aspect of the present invention, a weight data update button is provided at a predetermined location in the elevator car, and the call registration processing means performs the key registration after the key is authenticated. When the weight data update button is operated, the weight data of the elevator user is updated based on the detection result of the load detector.

  According to a sixth aspect of the present invention, in the invention according to any one of the first to fifth aspects, a refusal function cancel button operable after inputting predetermined password information is provided at a predetermined location in the elevator car. The call registration processing means, when the reject function cancel button is operated, performs the car call registration without determining whether or not the third party is in the car. It is characterized by that.

  The invention according to claim 7 is the invention according to any one of claims 1 to 6, wherein the operation control means monitors a detection signal from the passenger number detection means, and the car of the call registration processing means. When the number of passengers increases between call registration and before the elevator door closes, the operation is stopped regardless of the car call registration.

  According to the present invention, even if a third party subsequently enters the car following a user who has the right to go to a specific floor, the third party is prevented from going to the specific floor. Therefore, it is possible to prevent the security function for a specific floor from being damaged.

  FIG. 2 is a schematic configuration diagram of the entire elevator system according to the embodiment of the present invention. One end side of the rope 2 is attached to the car 1 arranged in the hoistway of the building, and the other end side of the rope 2 is attached to the counterweight 4 via the hoisting machine 3. And the elevator control apparatus 5 raises / lowers the car 1 by controlling the rotation of the hoisting machine 3.

  The building according to the present embodiment is a five-story building, and hall call buttons NB1 to NB5 are provided at the landings on each floor. The hall call signals when these hall call buttons NB1 to NB5 are operated are sent to the elevator controller 5 via the transmission path 6. In the present embodiment, a case where the second floor is a specific floor and the other floors are general floors will be described.

  FIG. 1 is a configuration diagram of an elevator control system according to an embodiment of the present invention. Key information assigned to a key (for example, an ID card) possessed by an elevator user is read by a key reading means (ID card reader) 7 and sent to a key authentication means 8. Various security data such as authentication data 10 and weight data 11 are stored in the security data storage unit 9, and the key authentication means 8 performs key authentication processing by comparing the input key information with the authentication data 10. The processing result is output to the call registration processing means 12.

  The call registration processing means 12 inputs a hall call signal from the hall call buttons NB1 to NB5 and a car call signal from the car call buttons KB1 to KB5, performs a call registration process, and outputs the processing result to the operation control means 13. It is supposed to be. The operation control means 13 operates the car 1 based on the processing result.

  The call registration processing means 12 also receives a load detection signal from the load detector 14 which is a passenger number detection means, an update request signal from the weight data update button 15, and a cancel request signal from the registration rejection function cancel button 16. It has come to be.

  When the processing result from the call registration processing unit 12 is registration refusal, the operation control unit 13 notifies a predetermined message using the display unit 17 and the voice output unit 18.

  In the configuration of FIG. 1, it is assumed that the key authentication unit 8, the security data storage unit 9, the call registration processing unit 12, and the operation control unit 13 are arranged in the elevator control device 5. The means 8 and the security data storage 9 can be arranged in the car 1.

  FIG. 3 is an explanatory diagram showing the arrangement configuration of each device in the car 1 that is stopped on the first floor, which is the entrance floor, and is waiting. In the car 1, the key reading means 7, the weight data update button 15, the registration refusal function cancel button 16, the display 17 and the audio output unit 18 described above with reference to FIG. An in-car operation panel 19 having call buttons KB1 to KB5 is also provided. The first floor hall where the hall call button NB1 is installed is a user M1 who is a fourth-floor resident, a user M2 who is a second-floor resident and has a key (ID card) 20, and a resident of the building. Not a third party M3 is waiting.

  Next, the operation of the present embodiment configured as described above will be described based on the flowchart of FIG. First, the case where the user M1 goes to the fourth floor which is his / her residence floor will be described. When the user M1 presses the hall call button NB1, the call registration processing means 12 registers the hall call from the first floor, and the operation control means 13 calls the car 1 back to the first floor based on the hall call registration and opens the door. Open. That is, it responds to the hall call (step 1). In the state where the car 1 has already arrived on the first floor and is waiting for the door to close, when the user M1 presses the hall call button NB1, the door is immediately opened.

  The user M1 gets into the car 1 after the door is opened. However, since the user M1 does not have the key, the car call on the car operation panel 19 is immediately performed without operating the key reading means 7. Press button KB4. Accordingly, the key authentication means 8 determines that there is no key input (step 2), and the call registration processing means 12 determines that there is a car call input and that the destination floor is not a specific floor (second floor) (step 3, 4). Then, the call registration processing means 12 registers the car call from the car call button KB4 (step 5), and the operation control means 13 drives the car 1 up to the fourth floor which is the destination floor based on this car call registration (step 5). Step 6).

  Next, the case where the user M2 goes to the second floor that is his / her residence floor, that is, a specific floor will be described. When the user M2 presses the hall call button NB1, the call registration processing means 12 registers this hall call as described above, and the operation control means 13 responds to this hall call (step 1).

  The user M2 gets into the car 1 after the door is opened, holds the key 20 possessed by the user M2 over the key reading means 7, and causes the key reading means 7 to read key information assigned in advance to the key 20. Like that. The key authentication means 8 performs authentication processing by comparing this key information with the authentication data 10 in the security data storage unit 9 and outputs the authentication processing result (in this case, “authentication success”) to the call registration processing means 12. To do. The call registration processing means 12 stores this authentication processing result in its own memory (steps 2 and 7).

  After receiving the authentication of the key 20 as described above, the user M2 presses the car call button KB2 on the in-car operation panel 19. Accordingly, the call registration processing means 12 determines that there is a car call input and that the destination floor is a specific floor (steps 3 and 4).

  Then, when the call registration processing means 12 reads out its own memory and determines that the result of the previous authentication processing is “authentication successful” (step 8), the call registration processing means 12 uses the data stored in the security data storage unit 9. The weight data 11 of the person M2 is compared with the load detected by the load detector 14 (step 9), and it is determined whether or not a third party other than the user M2 is in the car 1 (step 9). 10).

  In this case, since the weight data 11 and the detected load substantially coincide with each other, it is determined that the third party is not riding, and the determination result in step 10 is “NO”. Accordingly, the call registration processing means 12 registers the car call from the car call button KB2 (step 5), and the operation control means 13 moves the car 1 up to the second floor, which is the destination floor of the user M2, based on this car call registration. Run (step 6).

  Note that the call registration processing unit 12 determines that the detected load becomes larger in step 10 than the value obtained by adding the weight corresponding to the baggage (about 20 to 30 kg) to the weight data 11 of the user M2. It is determined that the person is in the car 1.

  Next, the case where the third person M3 gets into the car 1 following the user M2 when the elevator door is opened will be described. In this case, the steps up to step 8 are the same as in the above case where only the user M2 gets in. However, in the load detection in step 9, the load for two persons is detected, and the value of the detected load greatly exceeds the weight data 11 of the user M2, so that the call registration processing means 12 is carried by a third party in the car. The determination result in step 10 is “YES”. Therefore, the call registration processing means 12 refuses registration for the car call from the car call button KB2, and the operation control means 13 keeps the car 1 stopped without closing the door.

  When the determination result in step 10 is “YES”, the operation control means 13 gets out of the car 1 to the third party M3, or authenticates the key if possessing the key. Either or both of the items to be received are notified using the display device 17 or the audio output unit 18 (step 11), and waiting for the set time to elapse (step 12). Thereafter, the call registration processing means 12 again determines the presence / absence of a third party based on the load detection (steps 9 and 10), and the key authentication means 8 again determines the presence / absence of key input. (Step 2).

  Here, if the third party M3 gets off the car 1 before the set time elapses, the weight data 11 of the user M2 matches the detected load, so the determination result in step 10 is “NO”. The car call of the car call button KB2 is registered, and operation up to the second floor, which is the destination floor of the user M2, is performed (steps 5 and 6).

  Or, if the third party M3 has received key authentication before the set time has elapsed (that is, the third party M3 is actually a second-floor resident and has forgotten to receive key authentication in the previous step 2) ) The number of passengers detected by load detection is determined to be two, but the number of persons who have received key authentication is also two, so the determination result in step 10 is still “NO”, and the car call button KB2 is called Is registered and operation up to the second floor, which is the destination floor of the user M2 (and the third party M3), is performed (steps 5 and 6).

  However, even if the set time elapses, the state remains as it is, and when the third party M3 does not get off and does not receive key authentication, the operation control means 13 uses the car call button KB2 car. The call input is invalidated (step 13), and all the processes are terminated. Therefore, after this, when a new hall call is generated or a new car call is generated by another user who has entered the car 1, the call registration processing means 12 and the operation control means 13 make these new calls. Will respond to.

  If the determination result in step 8 is “NO”, that is, if the authentication processing result stored in step 7 is “authentication failure”, the user M2 forgets to receive key authentication. This is the case where the car call button KB2 is pressed with the key remaining valid, or the key has expired. Even in such a case, the operation control means 13 notifies the user M2 that the key authentication should be performed using the display 17 or the voice output unit 18 (step 14), and the set time elapses. (Step 15). If the user M2 has not received the key authentication even after the set time has elapsed, the car call input of the car call button KB2 is invalidated (step 13), and all the processes are terminated.

  As described above, according to the present embodiment, even if a third party M3 subsequently enters the car 1 following the user M2 who has the right to go to the second floor, which is a specific floor, Since the third party M3 can be prevented from going to the second floor, it is possible to prevent the security function for the second floor from being impaired.

  By the way, the weight of the user M2 is not always constant and may change to some extent as the period elapses. For example, in summer and winter, the weight data varies depending on the weight of clothes, or the weight data varies depending on the health condition. If only M2 is the authenticated user who rides in the car 1, this level of weight fluctuation will not be a problem. However, if a plurality of authorized users ride in the car 1 at the same time, the total value of such weight fluctuations is large. Therefore, there is a possibility that accurate detection of the number of passengers cannot be performed.

  The weight data update button 15 is provided assuming such a situation. For example, when the user M2 gets off the second floor (only M2 is in the car 1) and presses the weight data update button 15, the call registration processing means 12 inputs from the load detector 14 The detected load data is overwritten as weight data 11 stored in the security data storage unit 9. As a result, the latest weight data 11 is always stored in the security data storage unit 9, and the reliability of detecting the number of passengers can be maintained.

  Further, the user M2 may want to skip Steps 9 and 10 and immediately move from Step 8 to Steps 5 and 6. For example, this is a case where the user M2 gets in the car 1 together with a plurality of guests. In such a case, the user M2 can omit the steps 9 and 10 by operating the registration rejection function cancel button 16 (however, in order to validate this operation, the predetermined password information is required. Input is required). The weight data update button 15 and the registration refusal function cancel button 16 are not necessarily installed as dedicated buttons as shown in FIG. 3, and other buttons attached to the in-car operation panel 19 are switched by mode switching. It is also possible to adopt a configuration that can be used.

  The configuration of the present invention is generally as described in the above embodiment, but widely includes the following other forms.

(1) The operation control means 13 also inputs the detected load from the load detector 14 to monitor the number of passengers, and when the number of passengers increases after the call registration processing means 12 registers a car call on a specific floor. Regardless of this car call registration, it is possible to adopt a configuration in which the operation is stopped by performing the processing of steps 11 to 13 described above. According to this, after a car call to the second floor of the user M2 is registered, it is effective when a third party M3 gets into the car 1 accidentally or intentionally just before the door is closed. It becomes possible to cope with.

(2) After the car call is invalidated in Step 13 or Step 16, in order for the user M2 to go to the second floor, the user must go out of the car 1 and then repeat the process from Step 1. However, if the third party M3 is a malicious person, the same action is repeated and the car call is expected to be invalidated again. In preparation for such a case, it is possible to employ a configuration in which the operation control means 13 rings an alarm bell and notifies an administrator or a security company.

(3) In the above-described embodiment, the configuration using the load detector 14 as the passenger number detection means has been described, but an image processing apparatus can also be employed. Or if it is set as the structure which uses both a load detector and an image processing apparatus together, the reliability of passenger detection can further be improved.

(4) In the above embodiment, the case where the specific floor is only the second floor has been described. Of course, a plurality of floors can be set as the specific floor, and all the floors can be set as the specific floor. It is.

(5) In the above embodiment, the case where the key 20 possessed by the user M2 is an ID card has been described. However, the present invention is not limited to this. Other than that, a password is used or a biometric technique is used. A fingerprint or the like may be used.
