Detailed Description
The following describes a mode for carrying out the present invention with reference to the drawings.
< integral Structure >
Fig. 1 is a block diagram showing a configuration of a management system including a management server 10 as an embodiment of the present invention. As shown in fig. 1, the management server 10 and the vending machine A, B, C as a plurality of devices are connected via a network N. The management server 10 performs maintenance management such as data collection of the vending machine A, B, C and program update for the vending machine A, B, C. For example, the vending machine A, B, C is issued an update program to perform program update of the respective vending machine A, B, C via the network N. At this time, the management server 10 generates the device identification information DA, DB, and DC for uniquely identifying the vending machine A, B, C, and identifies the vending machine A, B, C to be managed using the generated device identification information DA, DB, and DC.
The vending machine A, B, C is an example of an apparatus, and includes communication identification information D10A, D10B, and D10C, and local apparatus identification information D20A, D20B, and D20C, respectively. The communication identification information D10A, D10B, and D10C are unique communication identification information for communication connection, and examples thereof include an IP address (Internet Protocol address), an IMSI (International Mobile Subscriber Identity) in a SIM Card (Subscriber Identity Module Card) for wireless communication connection, and the like. The local device identification information D20A, D20B, and D20C are device identification information assigned locally by each company, and are, for example, a device code (a device code assigned by each company as a serial number) and a location code (an installation location code of a vending machine).
The management server 10 uses a hash function to generate hash values for text information obtained by combining one or more communication identification information D10A, D10B, D10C and one or more local device identification information D20A, D20B, D20C, and registers and manages the hash values as device identification information DA, DB, DC for each vending machine A, B, C in the management server 10 and each vending machine A, B, C.
< Structure of management Server >
As shown in fig. 1, the management server 10 includes an input unit 11, a display unit 12, a communication unit 13, a storage unit 14, and a control unit 15.
The input unit 11 is an input device such as a keyboard or a mouse, the display unit 12 is a display device such as a liquid crystal panel, and the communication unit 13 is a communication interface unit for connecting to each vending machine A, B, C via the network N.
The storage unit 14 is a storage device including a hard disk device, a nonvolatile memory, and the like, and stores the hash function H and management information D including device identification information DA, DB, and DC.
The control unit 15 is a control unit for controlling the entire management server 10, and includes a communication identification information acquisition unit 21, a local information acquisition unit 22, a hash value generation unit 23, and a management unit 24. The control unit 15 executes corresponding processing by storing programs corresponding to the communication identification information acquisition unit 21, the local information acquisition unit 22, the hash value generation unit 23, and the management unit 24 in a storage device such as a nonvolatile memory or a magnetic disk device in advance, loading the programs into a memory, and executing the programs by a CPU.
The communication identification information acquiring unit 21 acquires the IP addresses and IMSIs of one or more pieces of communication identification information D10A, D10B, and D10C, which are unique pieces of communication identification information for communication connection of the individual vending machines A, B, C. The communication identification information D10A, D10B, and D10C may be acquired from the individual vending machine A, B, C, or may be acquired from the management server 10 when the management server 10 itself manages the communication identification information D10A, D10B, and D10C.
The local information acquirer 22 acquires one or more device codes and location codes as the local device identification information D20A, D20B, and D20C set locally for each vending machine A, B, C. The local device identification information D20A, D20B, and D20C may be acquired from the individual vending machine A, B, C, or may be acquired from the management server 10 when the local device identification information D20A, D20B, and D20C are managed by the management server 10 itself.
The hash value generation unit 23 generates a hash value by using a hash function H for text information obtained by combining one or more communication identification information pieces D10A, D10B, and D10C and one or more local device identification information pieces D20A, D20B, and D20C.
The management unit 24 manages the hash value generated for each vending machine A, B, C as the device identification information DA, DB, DC for each vending machine A, B, C, and registers the hash value in each vending machine A, B, C.
< creation and management of device identification information >
Next, the generation and management processing procedure of the device identification information DA, DB, DC by the control unit 15 will be described with reference to a flowchart shown in fig. 2. Fig. 2 is a flowchart showing the procedure of the process of generating and managing the device identification information DA, DB, and DC by the control unit 15.
As shown in fig. 2, first, the control unit 15 selects one of the vending machines A, B, C as a device (step S110). Thereafter, the communication identification information acquiring unit 21 acquires the communication identification information D10A, D10B, D10C (step S120). After that, the local information acquirer 22 acquires the local device identification information D20A, D20B, D20C (step S130).
Then, the hash value generation unit 23 generates a hash value by using the hash function H for text information obtained by combining one or more pieces of communication identification information D10A, D10B, D10C and one or more pieces of local device identification information D20A, D20B, D20C (step S140).
The management unit 24 manages the generated hash value as the device identification information DA, DB, and DC of the selected vending machine, and registers the hash value in the selected vending machine (step S150).
After that, the control unit 15 determines whether or not all the vending machines have been selected (step S160). In the case where all the vending machines have not been selected (step S160: NO), the flow proceeds to step S110, and the next vending machine is selected to repeat the above-described processing. On the other hand, when all the vending machines have been selected (step S160: YES), the present process is ended.
< example of device identification information >
Fig. 3 is a diagram showing an example of the device identification information DA, DB, DC generated by each vending machine A, B, C. As shown in fig. 3, each vending machine A, B, C has a communication function of directly connecting to the network N, and therefore has a global IP address. In addition, since wireless communication is performed, IMSI is also included. In addition, each vending machine A, B, C has a local machine code and location code. In addition, the first "440" in the IMSI indicates a country number, and the next "10" indicates an identification number of a carrier.
Thus, in fig. 3, text information is generated which includes the global IP address and IMSI as 2 pieces of communication identification information and the machine code and the location code as 2 pieces of local device identification information, and a hash value of a fixed length of 32 bits (128 bits) is generated for this arbitrary length of text information using, for example, the hash function MD 5. The hash value is device identification information of each mobile vending machine. Since the hash function changes text information of an arbitrary length into a hash value of a fixed length, it is preferable to use a plurality of pieces of communication identification information and a plurality of pieces of local apparatus identification information as many as possible.
< modification example >
As shown in fig. 4, each vending machine A, B, C may be connected to the network N via one router 30. In this case, as shown in fig. 5, although the IP address is a local IP address, the IP address is different in each vending machine A, B, C. Further, since the router has a wireless communication function, the IMSI is the same value for each vending machine A, B, C. In addition, although the machine codes are different, the position codes are the same value.
As described above, although the same communication identification information and the same local device identification information may be present depending on the communication connection method, at least the IP address and the device code are different from each other even in this case, and thus it is possible to assign unique device identification information to the vending machine and register the device identification information by combining them. In the present modification, a hash function MD5 for generating a 128-bit hash value is also used.
In the above-described embodiment and modification, the management server 10 generates the device identification information, but the present invention is not limited to this, and the device identification information may be generated by another device, distributed to the vending machine A, B, C, and registered in the management server 10.
As described above, in the present embodiment and the modification, a hash value is generated using a hash function for text information obtained by combining one or more pieces of communication identification information of the vending machine and one or more pieces of local device identification information of the vending machine, and the hash value is registered and managed as unique device identification information in the vending machine, so that remote processing is not executed at all for a wrong vending machine.
Note that each configuration illustrated in the above-described embodiment and modification is a schematic functional configuration, and it is not necessarily required to physically have a configuration as illustrated in the drawings. That is, the way of dispersing and combining the respective devices and components is not limited to the illustrated way, and all or a part of them may be configured to be functionally or physically dispersed and combined in arbitrary units according to various usage situations and the like.
