Fig. 6 is a flowchart for explaining an outline of the operation of the security management device 1 according to embodiment 1. Fig. 7 is a flowchart for explaining an outline of the operation of the mobile terminal 15 according to embodiment 1. Fig. 8 is a diagram showing an example of the mobile terminal 15 in which the operation screen is displayed on the display unit 152. Fig. 9 is a flowchart for explaining an outline of the operation of the control panel 6 according to embodiment 1. Fig. 10 is a flowchart for explaining an outline of the operation of the server 16 according to embodiment 1.
An example is shown in which a user 14 moves from floor 4 to floor 3 using an elevator apparatus. The user 14 approaches the 4-story landing 9. The user 14 brings the mobile terminal 15 close to the communication device 13 to a distance at which communication with the communication device 13 is possible. The proximity communication is started by the proximity of the portable terminal 15 to a distance that enables communication with the communication device 13. The present security system is started to be utilized by starting the near field communication.
The security management device 1 determines whether or not the receiving unit 131 of the communication device 13 can communicate with the mobile terminal 15 (S101). If the receiving unit 131 can communicate with the mobile terminal 15, it is determined as yes in S101. When the receiving unit 131 cannot communicate with the mobile terminal 15, it is determined as no in S101. If it is determined as no in S101, it is continuously determined whether or not the receiving unit 131 can communicate with the mobile terminal 15.
In the mobile terminal 15, it is determined whether or not the receiving unit 157 can communicate with the communication device 13 (S201). If the receiving unit 157 can communicate with the communication device 13, it is determined as yes in S201. If the receiving unit 157 cannot communicate with the communication device 13, it is determined as no in S201. If yes is determined in S201, a request R of information necessary for call registration of the car is generated by the request section 155. The transmission unit 156 transmits a request R for information to the communication device 13 (S202).
When it is determined as yes in S101, the security management device 1 determines whether or not the receiving unit 131 has received the request R for information from the mobile terminal 15 (S102). When the receiving unit 131 receives the request R from the mobile terminal 15, it is determined as yes in S102. When the receiving unit 131 does not receive the request R from the mobile terminal 15, it is determined as no in S102. If it is determined as no in S102, it is continuously determined whether or not the request R is received from the mobile terminal 15.
If it is determined as yes in S102, the processing unit 122 of the information management device 12 generates authentication information (S103). The authentication information is used to prevent the user 14 from analyzing the communication and maliciously performing call registration of the car via the server 16. Each time it is determined as yes in the process of S102, the authentication information of the same content is generated. The authentication information is stored in the storage unit 123. The storage unit 123 stores in advance an elevator number and management floor information. The elevator number is information for identifying a specific elevator apparatus from among a plurality of elevator apparatuses located in a building. The elevator number may be information for identifying a bank that is a set of a plurality of cars 2. The management floor information is information of a floor at which the car 2 can stop. The management floor information is information indicating all the stop floor identification information of the elevator apparatus for which call registration of the car is performed. The contents of the management floor information of the building 100 show "1F, 2F, 3F, 4F, 5F". In S104, the transmission unit 132 of the safety management device 1 transmits the elevator number, the management floor information, and the authentication information to the mobile terminal 15. The authentication information transmitted in S104 is taken as authentication information a.
In the safety management device 1, when the elevator number, the management floor information, and the authentication information a are transmitted in S104, the communication with the mobile terminal 15 is immediately cut off (S105). As a result, communication with other portable terminals is enabled. This enables immediate processing even when a large number of users approach the communication device 13 at the same time. This prevents a plurality of users from being crowded around the communication device 13.
The receiving unit 157 of the mobile terminal 15 determines whether or not the elevator number, the management floor information, and the authentication information a are received from the safety management device 1 as a response to the request R transmitted in S202 (S203). When the elevator number, the management floor information, and the authentication information a are received from the safety management device 1, it is determined as yes in S203. If the elevator number, the management floor information, and the authentication information a are not received from the safety management device 1, it is determined as no in S203. If it is determined as no in S203, it is continuously determined whether or not the elevator number, the management floor information, and the authentication information a are received by the receiving unit 157 as a response to the request R transmitted in S202. If it is determined as yes in S203, the received elevator number, management floor information, and authentication information a are stored in storage unit 154 (S204). In S205, the receiving unit 157 of the mobile terminal 15 immediately cuts off the communication with the safety management device 1 after receiving the elevator number, the management floor information, and the authentication information a. By terminating the short-range communication with the communication device 13 by the portable terminal 15, the user 14 no longer needs to stay around the communication device 13. This enables the next user to smoothly start using the security system.
In the mobile terminal 15, the processing unit 153 reads the management floor information (S206). In S207, the display unit 152 displays the possible destination floors that are candidates for floors to which the user 14 can move in the building 100, based on the management floor information read by the processing unit 153. In the building 100 having 5 floors, the user 14 is using 4 floors, and hence "1F, 2F, 3F, 5F" are floors on which a destination is possible.
Fig. 8 is a diagram showing an example of the mobile terminal 15 in which the operation screen is displayed on the display unit 152. On the operation screen, a display such as "please press the destination floor" is displayed. The user 14 is prompted to perform an operation by displaying the operation screen. The destination-possible floor is displayed on the operation screen. For example, on the operation screen, "1" indicating 1 layer, "2" indicating 2 layers, "3" indicating 3 layers, and "5" indicating 5 layers are displayed. Since the user 14 is utilizing 4 tiers, "4" is not displayed so that "4" is not selected. The user 14 can select a destination floor from the display of destination floor possibilities by clicking "3" indicating 3 floors as destination floors. In addition, when the destination floor cannot be displayed completely on one screen, the destination floor may be displayed on a plurality of pages or may be displayed by scrolling.
It is determined whether or not a destination floor is input from the user 14 to the input unit 151 of the mobile terminal 15 (S208). When the destination floor is input from the user 14, it is determined as yes in S208. If the destination floor is not input from the user 14, the determination at S208 is no. If it is determined as no in S208, it is continuously determined whether or not a destination floor is input from the user 14. If yes is determined in S208, the processing unit 153 generates call registration information based on the input of the destination floor (S209). In S210, it is determined whether or not the transmission unit 156 can communicate with the server 16. If the transmission unit 156 can communicate with the server 16, it is determined as yes at S210. If the transmission unit 156 cannot communicate with the server 16, it is determined as no in S210. If it is determined as no in S210, it is continuously determined whether or not communication with the server 16 is possible.
In the server 16, it is determined whether or not the receiving unit 163 can communicate with the mobile terminal 15 (S401). If the receiving unit 163 can communicate with the mobile terminal 15, it is determined as yes in S401. When the reception unit 163 cannot communicate with the mobile terminal 15, it is determined as no in S401. If it is determined as no in S401, it is continuously determined whether or not the receiver 163 can communicate with the mobile terminal 15.
When the mobile terminal 15 determines yes at S210, the transmission unit 156 transmits the elevator number, the authentication information a, and the call registration information to the server 16 (S211). When the process of S211 ends, the process of the portable terminal 15 ends.
When the server 16 determines yes in S401, it determines whether or not the elevator number, the authentication information a, and the call registration information are received from the mobile terminal 15 by the receiving section 163 (S402). When the elevator number, the authentication information a, and the call registration information are received from the mobile terminal 15 by the receiving unit 163, it is determined as yes in S402. When the receiving unit 163 does not receive the elevator number, the authentication information a, and the call registration information from the portable terminal 15, the determination at S402 is no. If it is determined as no in S402, it is continuously determined whether or not the elevator number, the authentication information a, and the call registration information are received from the portable terminal 15. If it is determined as yes in S402, the received elevator number, authentication information a, and call registration information are stored in the storage unit 162 (S403). In S404, the processing unit 161 reads an elevator number. The processing unit 161 determines the control panel 6 as the destination of the authentication information a and the call registration information based on the information of the read elevator number.
In S106, the safety management device 1 determines whether or not the transmitter 121 can communicate with the control panel 6. If the transmission unit 121 can communicate with the control panel 6, it is determined as yes in S106. If the transmission unit 121 cannot communicate with the control panel 6, it is determined as no in S106. If it is determined as no in S106, it is continuously determined whether or not the transmitter 121 can communicate with the control panel 6.
In the control panel 6, it is determined whether or not the receiving unit 61 can communicate with the security management device 1 (S301). If the receiving unit 61 is able to communicate with the security management device 1, it is determined as yes in S301. When the receiving unit 61 cannot communicate with the security management device 1, it is determined as no in S301. If it is determined as no in S301, it is continuously determined whether or not the receiving unit 61 can communicate with the security management device 1.
When it is determined as yes in S106, the security management device 1 transmits the authentication information to the control panel 6 by the transmission unit 121 (S107). The authentication information transmitted in S107 is the information generated by the processing section 122 in S103. The content of the authentication information transmitted in S107 is the same as the authentication information a transmitted in S104. The authentication information transmitted in S107 is set as authentication information B. The authentication information generated by the processing unit 122 is transmitted to the control panel 6 as authentication information B. When the process of S107 ends, the process of the security management device 1 ends.
When the control panel 6 is determined as yes in S301, it is determined whether or not the authentication information B is received from the security management device 1 by the receiving unit 163 (S302). When the authentication information B is received from the security management device 1 by the receiving unit 163, it is determined as yes in S302. If the receiving unit 163 does not receive the authentication information B from the security management device 1, it is determined as no in S302. If it is determined as yes in S302, the authentication information B is stored in the storage unit 62 (S303).
In the server 16, it is determined whether or not the transmission unit 164 can communicate with the control panel 6 specified in S404 (S405). If the transmission unit 164 can communicate with the control panel 6, it is determined as yes in S405. If the transmission unit 164 cannot communicate with the control panel 6, it is determined as no in S405. If it is determined as no in S405, it is continuously determined whether or not communication with the control panel 6 is possible.
In S304, the control panel 6 determines whether or not the receiving unit 61 can communicate with the server 16. If the receiving unit 61 is able to communicate with the server 16, it is determined as yes in S304. If the receiving unit 61 cannot communicate with the server 16, it is determined as no in S304.

In the control panel 6, the verification unit 63 verifies the authentication information a and the authentication information B (S307). The matching unit 63 determines whether the authentication information a matches the authentication information B (S308). When the authentication information a and the authentication information B match, the matching unit 63 determines that the matching is successful. In this case, it is determined as yes in S308. This proves that the call registration of the car is performed by the portable terminal 15. Therefore, the call registration of the car by the user 14 is authenticated. When the authentication information a does not match the authentication information B, the matching unit 63 determines that the matching has failed. In this case, the determination at S308 is no. Thus, it cannot be verified that the call registration of the car is performed by the portable terminal 15. This makes the call registration of the car by the user 14 unauthenticated. If it is determined as no in S308, the process of the control panel 6 is ended. If it is determined as yes in S308, the processing unit 64 reads the call registration information. The processing unit 64 specifies the destination floor of the car 2 based on the read information (S309). In S310, the control unit 65 controls the car 2. In S310, the control unit 65 moves the car 2 from 4 floors to 3 floors (S310). The user 14 moves from 4 floors to 3 floors using the car 2. When the process of S310 is completed, the process of the control panel 6 is completed.
In this embodiment, the authentication information a and the call registration information are transmitted from the portable terminal 15 to the control panel 6 via the server 16, but the authentication information a and the call registration information may be transmitted directly from the portable terminal 15 to the control panel 6. In this case, the processing unit 153 of the portable terminal 15 reads the elevator number. The control panel 6 as the transmission destination is specified based on the information read by the processing unit 153.
In this embodiment, the control panel 6 is specified based on the elevator number, but if the safety system is configured by only one elevator apparatus, the control panel 6 of the destination elevator apparatus is clear. Thus, if the safety system includes only 1 elevator apparatus, it is not necessary to specify the control panel 6. In this case, the elevator number is not required. Thus, if the safety system is provided with only 1 elevator apparatus, the control panel 6 does not need to be specified.
According to embodiment 1 described above, the dedicated application does not include the management floor information of the elevator device to be used in advance. The dedicated application acquires the management floor information after the security system is started to be used. Thus, even an elevator apparatus which cannot register in advance, such as a visiting destination or a commercial facility, can immediately register a call to a car using the portable terminal 15. Further, even when the user 14 first uses the present security system, the user can immediately start using the security system. Further, the mobile terminal 15 does not need to hold the user registration information or input the user registration information into the mobile terminal 15. This enables call registration of the car using the mobile terminal 15 to be performed without using user information or mobile terminal information. Thus, any user of the elevator apparatus can immediately use the safety system.
Further, the user 14 can register the destination floor using the portable terminal 15. Thus, the call registration of the car can be performed without using the hall operation panel 10a and the in-car operation panel 10b. In fig. 1, the hall operation panel 10a and the in-car operation panel 10b are provided for users who do not hold the portable terminal, but when the users all hold the portable terminal, the hall operation panel 10a and the in-car operation panel 10b are not necessary. Thus, the user can use the elevator apparatus without touching the landing operating panel 10a and the in-car operating panel 10b. This improves the sanitary state in the landing 9 and the car 2. Further, when there are a plurality of users, it is possible to prevent the vicinity of the landing operating panel 10a and the in-car operating panel 10b from being crowded.
The control panel 6 checks the authentication information B directly transmitted from the security management device 1 to the control panel 6 against the authentication information a transmitted via the mobile terminal 15. This can prevent the user 14 from analyzing the communication and maliciously performing call registration of the car from outside the building 100 via the server 16.
The portable terminal 15 acquires the authentication information a from the communication device 13 by near field communication. Thereby, only the portable terminal 15 in the communication range of the communication device 13 can acquire the authentication information a. This can prevent the user 14 from performing call registration of a car illegally from outside the building 100.
The portable terminal 15 transmits the elevator number, the authentication information a, and the call registration information via the server 16. Thus, the safety management device 1 can cut off communication after transmitting the elevator number, the management floor information, and the authentication information a. This enables immediate processing even when a large number of users approach the communication device 13 at the same time. This can prevent a situation in which a plurality of users stay around the communication device 13.
Next, an example of hardware constituting the security management apparatus 1 will be described with reference to fig. 16.
Fig. 16 is a hardware configuration diagram of the security management apparatus 1 according to embodiment 1.
The functions of the security management device 1 may be implemented by a processing circuit. The processing circuitry is provided with at least one processor 1001 and at least one memory 1002. The processing circuit may also be provided with at least one dedicated piece of hardware 1003.
When the processing circuit includes the processor 1001 and the memory 1002, each function of the security management apparatus 1 is realized by software, firmware, or a combination of software and firmware. At least one of the software and the firmware is described as a program. At least one of software and firmware is stored in the memory 1002. The processor 1001 realizes each function of the security management apparatus 1 by reading out and executing a program stored in the memory 1002. The processor 1001 is also referred to as a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, or a DSP. The Memory 1002 is a nonvolatile or volatile semiconductor Memory such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash Memory, an EPROM (Erasable Programmable Read Only Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory), a magnetic Disk, a flexible Disk, an optical Disk, a CD (compact Disk), a mini Disk (mini Disk), a DVD (Digital Versatile Disk), or the like.
When the processing Circuit includes the dedicated hardware 1003, the processing Circuit is implemented by a single Circuit, a composite Circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof. The functions of the security management device 1 may be implemented by the processing circuit. The functions of the security management apparatus 1 may be realized collectively by a processing circuit.
The functions of the security management apparatus 1 may be implemented partially by dedicated hardware 1003 and partially by software or firmware. The function of generating the authentication information may be realized by a processing circuit as dedicated hardware 1003, and the functions other than the function of generating the authentication information may be realized by the processor 1001 reading out and executing a program stored in the memory 1002.
In this way, the processing circuit implements each function of the security management apparatus 1 by hardware 1003, software, firmware, or a combination thereof.
Although not shown, the functions of the mobile terminal 15 may be realized by a processing circuit equivalent to the processing circuit for realizing the functions of the security management apparatus 1.
Although not shown, each function of the server 16 may be realized by a processing circuit equivalent to a processing circuit for realizing each function of the security management apparatus 1.
Although not shown, each function of the control panel 6 may be realized by a processing circuit equivalent to a processing circuit for realizing each function of the security management apparatus 1.
In embodiment 1, an example is shown in which the authentication information generated by the security management apparatus 1 is checked by the control panel 6 as the authentication information a and the authentication information B. In the present embodiment, an example will be described in which the authentication information is given an expiration date in the security management device 1, and the expiration date is determined in the control panel 6. The configuration of the security system of the present embodiment is the same as the example shown in fig. 1.
Fig. 11 is a flowchart for explaining an outline of the operation of the security management device 1 according to embodiment 2. Fig. 12 is a flowchart for explaining an outline of the operation of the control panel 6 according to embodiment 2. The same or corresponding portions as those in embodiment 1 are denoted by the same reference numerals. The description of this part is omitted.
Steps shown in S501 to S503 of fig. 11 are the same as steps shown in S101 to S103 of fig. 6. In S504, the processing unit 122 assigns an expiration date to the authentication information. Steps shown in S505 to S508 of fig. 11 are the same as steps shown in S104 to S107 of fig. 6.
Steps shown in S601 to S606 of fig. 12 are the same as those shown in S301 to S306 of fig. 9. In S607, the collation unit 63 determines whether or not the authentication information a received from the server 16 is within the expiration date assigned in S504. If the authentication information a is within the validity period, it is determined as yes. When the authentication information a exceeds the expiration date, it is determined as no. If it is determined as no in S607, the process of the control panel 6 is ended and the control of the car 2 is not performed. If yes is determined in S607, the process of S608 is performed. The steps shown in S608 to S611 of fig. 12 are the same as those shown in S307 to S310 of fig. 9.
Further, the validity period is given to both the authentication information a and the authentication information B, but the validity period may be given to only the authentication information a or only the authentication information B.
The validity period is determined only for the authentication information a, but may be determined only for the authentication information B or for both.
The expiration date is determined by the control panel 6, but may be determined by the server 16. The expiration date may be determined by both the server 16 and the control panel 6. Since the safety system is a system for preventing abuse of the elevator apparatus, it is preferably performed by the control panel 6.
According to embodiment 2 described above, the authentication information is given a term of validity. This prevents the user 14 from illegally calling a car via the server 16 by analyzing the communication and copying the authentication information.
In the present embodiment, an example in which the authentication information is updated by the security management apparatus 1 will be described. The configuration of the security system of the present embodiment is the same as the example shown in fig. 1.
Fig. 13 is a flowchart for explaining an outline of an operation of updating authentication information of the security management apparatus 1 according to embodiment 3. Fig. 14 is a flowchart for explaining an outline of the operation of the security management apparatus 1 according to embodiment 3. Fig. 15A is a flowchart for explaining an outline of the operation of the control panel 6 according to embodiment 3. Fig. 15B is a flowchart for explaining an outline of the operation of the control panel 6 according to embodiment 3. The same or corresponding portions as those in embodiment 1 are denoted by the same reference numerals. The description of this part is omitted.
An example of updating the authentication information in the security management apparatus 1 is shown. In the security management device 1, the processing unit 122 generates authentication information (S701). The authentication information generated in S701 is stored in the storage unit 123. The storage unit 123 holds the authentication information generated in S701 (S702). In S703, it is determined whether or not a predetermined time has elapsed since the processing unit 122 generated the authentication information. If a predetermined time has elapsed since the authentication information was generated, it is determined as yes in S703. If the time is within the predetermined time from the generation of the authentication information, it is determined as no in S703. If it is determined as no in S703, it is continuously determined whether or not a predetermined time has elapsed. If it is determined as yes in S703, the processing unit 122 deletes the authentication information (S704). After the authentication information is deleted in S704, the process returns to S701, and the authentication information having the content different from the last time is generated. By the processing described above, the authentication information is updated by the security management apparatus 1 at any time.
An example in which the authentication information is periodically updated 5 times by the security management apparatus 1 will be described. In the following, when the authentication information needs to be specified, the 5 pieces of authentication information generated are denoted by reference numerals a to e. The authentication information a transmitted to the mobile terminal 15 by the transmission unit 132 is also denoted by the same reference numerals a to e. The authentication information B transmitted to the control panel 6 by the transmission unit 121 is also labeled with the same reference numerals a to e. When the present security system is used between the first update and the second update, between the third update and the fourth update, and between the fourth update and the fifth update, the authentication information a, the authentication information c, and the authentication information d are acquired in the processing of S803.
The security management apparatus 1 periodically updates the authentication information. The safety system is used for one time between the first updating and the second updating and between the third updating and the fourth updating, and the safety system is used for two times in total. An example is shown where the user 14 begins using the present security system between the fourth and fifth updates. The steps shown in S801 to S802 are the same as those shown in S101 to S102 of fig. 6. In the security management device 1, if it is determined as yes in S802, the processing unit 122 acquires the authentication information d held in the storage unit 123 (S803). The steps shown in S804 to S807 of fig. 14 are the same as those shown in S104 to S107 of fig. 6. In S804, the authentication information a transmitted by the transmission unit 132 is the information acquired in S803. In S804, the transmission unit 132 transmits the authentication information Ad. In S807, the authentication information B transmitted by the transmission unit 121 is the information acquired in S803. In S807, the authentication information Bd is transmitted by the transmission unit 121. In the processing of S804, the authentication information Aa is transmitted when the present security system is used between the first update and the second update, and the authentication information Ac is transmitted when the present security system is used between the third update and the fourth update. In the processing of S807, the authentication information Ba is transmitted when the present security system is used between the first update and the second update, and the authentication information Bc is transmitted when the present security system is used between the third update and the fourth update.
The storage unit 62 of the control panel 6 sets an upper limit N of the number of authentication information B received from the security management device 1 to be stored. When the upper limit value N is 2, the storage unit 62 stores at most two pieces of authentication information B received from the transmission unit 121. The storage unit 62 stores the authentication information B in descending order of date and time when the authentication information B is received within the range of the upper limit value N. When the user 14 starts using the present security system, the two pieces of authentication information B are stored in the storage unit 62 in the order of the authentication information Bc and the authentication information Ba.
The step S901 of the control panel 6 is the same as the step S301 of fig. 9. When the authentication information Bd is received by the receiving unit 61, it is determined as yes in S901. If yes is determined in S901, it is determined whether or not the number of authentication information B stored in the storage unit 62 is equal to or less than the number obtained by subtracting 1 from the upper limit value N (S902). When the upper limit N is two, it is determined in S902 whether or not the number of authentication information B is one or less. If the number of authentication information B stored in the storage unit 62 is one or less, it is determined as yes in S902. When the number of pieces of authentication information B stored in the storage unit 62 is more than one, that is, when there are two pieces, it is determined as no in S902. If it is determined as no in S902, the oldest one of the authentication information B stored in the storage unit 62 is deleted (S903). The storage unit 62 stores two pieces of authentication information in the order of the authentication information Bc and the authentication information Ba, and the authentication information B with the earliest reception date and time is the authentication information Ba. Thereby, the authentication information Ba is deleted. If it is determined as yes in S902 or if the process in S903 is completed, the authentication information B received in S901 is stored in the storage unit 62 (S904). In S904, the authentication information Bd is stored in the storage unit 62. When the processing in S904 is completed, the storage unit 62 stores the authentication information B in the order of the authentication information Bd and the authentication information Bc.
The steps shown in S905 to S907 of fig. 15B are the same as those shown in S304 to S306 of fig. 9. In S907, the authentication information Ad is stored in the storage unit 62. In S908, the verification unit 63 verifies the authentication information a received from the server 16 against the latest authentication information B stored in the storage unit 62. The storage unit 62 stores authentication information Bd and authentication information Bc, and the latest date and time of reception is the authentication information Bd. Thereby, the authentication information Ad and the authentication information Bd are collated in S907. In S909, it is determined whether the verified authentication information a and the authentication information B match. If the verified authentication information a matches the authentication information B, it is determined as yes in S909. If the verified authentication information a does not match the authentication information B, the determination at S909 is no. Since the authentication information Ad matches the authentication information Bd, it is determined as yes in S909. If it is determined as no in S909, the collating section 63 collates the authentication information a received from the server 16 with the second old authentication information B stored in the storage section 62 (S910). In S911, the verification unit 63 determines whether or not the verified authentication information a and the verified authentication information B match each other. If the verified authentication information a matches the authentication information B, it is determined as yes in S911. If the verified authentication information a does not match the authentication information B, it is determined as no in S911. If the determination is "no", the process of the control panel 6 is ended. If it is determined to be yes in S911, the process of S912 is started. Steps shown in S912 to S913 of fig. 15B are the same as those shown in S309 to S310 of fig. 9. After the process of S913 ends, the process of the control panel 6 ends.
Further, the authentication information B is stored in the storage unit 62 in descending order of reception date and time, but the authentication information B may be stored in other order. The authentication information B may be stored in the storage unit 62 in ascending order of reception date and time. In this case, in the processing of S903, the oldest authentication information among the authentication information B stored in the storage unit 62 is deleted regardless of the order of the storage unit 62.
The verification unit 63 performs verification from the latest authentication information B stored in the storage unit 62 with respect to the authentication information B, but other procedures are also possible. The verification unit 63 may perform verification of the authentication information B stored in the storage unit 62 in ascending order of reception date and time.
According to embodiment 3 described above, the content of the authentication information is periodically updated by the security management apparatus 1. The control panel 6 stores a predetermined number of pieces of authentication information B received from the security management device 1 in descending order of reception date and time. When the authentication information B stored in the storage unit 62 exceeds a predetermined number, the authentication information B is deleted in ascending order of reception date and time. The matching unit 63 determines whether or not any of the stored authentication information B matches the authentication information a received from the server 16. This deletes the old authentication information B, thereby adding the validity period to the authentication information B. This prevents the user 14 from analyzing the communication and copying the authentication information to make a car call via the server 16. Further, the determination of the expiration date in embodiment 2 is not necessary. This improves the processing speed.
