Information management device, network system, information management program, and information management method

A network system comprising:

• a plurality of sensors that generate sensing data;
• a plurality of applications that require the sensing data;
• and
• an information management device that relays the sensing data between the sensors and the applications, the sensors, the applications, and the information management device being connected in a communicable manner, the information management device including:
• a provision condition storage unit in which, for each sensor, provision condition information of sensing data generated by a sensor is registered in association with identification information of the sensor;
• a use condition storage unit in which, for each application that requires use of the sensing data, use condition information of the sensing data required by an application is registered in association with an address of a transmission destination of the sensing data;
• a sensing data acquisition unit that acquires through communication the sensing data generated by the sensor registered in the provision condition storage unit;
• a specification unit that specifies the provision condition information matched with the use condition information by searching the provision condition storage unit for each piece of the use condition information registered in the use condition storage unit;
• and
• a sensing data delivery unit that performs a transmission process in which, to a transmission destination address corresponding to the use condition information with which the specification unit has specified the provision condition information matched, the sensing data that the sensing data acquisition unit has acquired through communication with the sensor having the identification information in association with the provision condition information matched with the use condition information is transmitted.

An information management program stored on a non-transitory computer-readable medium for causing a computer to perform:

• a first step of registering in a provision condition storage unit, for each sensor, provision condition information of sensing data generated by a sensor in association with identification information of the sensor;
• a second step of registering in a use condition storage unit, for each application that requires use of the sensing data, use condition information of the sensing data required by an application in association with an address of a transmission destination of the sensing data;
• a third step of acquiring through communication the sensing data generated by the sensor registered in the provision condition storage unit;
• a fourth step of specifying the provision condition information matched with the use condition information by searching the provision condition storage unit for each piece of the use condition information registered in the use condition storage unit;
• and
• a fifth step of performing a transmission process in which, to a transmission destination address corresponding to the use condition information of which matched provision condition information has been specified in the fourth step, the sensing data that has been acquired in the third step through communication with the sensor having the identification information in association with the matched provision condition information is transmitted.

An information management method executed by a computer, the method comprising:

• a first step of registering in a provision condition storage unit, for each sensor, provision condition information of sensing data generated by a sensor in association with identification information of the sensor;
• a second step of registering in a use condition storage unit, for each application that requires use of the sensing data, use condition information of the sensing data required by an application in association with an address of a transmission destination of the sensing data;
• a third step of acquiring through communication the sensing data generated by the sensor registered in the provision condition storage unit;
• a fourth step of specifying the provision condition information matched with the use condition information by searching the provision condition storage unit for each piece of the use condition information registered in the use condition storage unit;
• and
• a fifth step of performing a transmission process in which, to a transmission destination address corresponding to the use condition information of which matched provision condition information has been specified in the fourth step, the sensing data that has been acquired in the third step through communication with the sensor having the identification information in association with the matched provision condition information is transmitted.
