Communication device, communication method, and recording medium

A communication method to be performed by a communication device that communicates, in a first cycle, with sensors connected through a network to acquire, from each of the sensors, measurement data measured by the sensors in data acquisition cycles longer than or equal to the first cycle and stores the measurement data in a storage, the communication method comprising:

• classifying, by a grouping section of the communication device, the sensors into groups based on the data acquisition cycles, acquiring the measurement data from the sensors classified into the groups, and then reclassifying one sensor of the sensors into a different group of the groups when determining that a maximum size of data to be received through the network per first cycle exceeds a threshold for a communication band of the network;
• and
• calculating, by a memory map generator of the communication device, a timing and an address to store the measurement data in the storage based on the data acquisition cycles and the groups resulting from the classification.

A non-transitory computer-readable recording medium storing a program, the program causing a computer to implement a communication method including communicating, in a first cycle, with sensors connected through a network to acquire, from each of the sensors, measurement data measured by the sensors in data acquisition cycles longer than or equal to the first cycle and to store the measurement data in a storage, the program causing the computer to perform operations comprising:

• classifying the sensors into groups based on the data acquisition cycles, acquiring the measurement data from the sensors classified into the groups, and then reclassifying one sensor of the sensors into a different group of the groups when determining that a maximum size of data to be received through the network per first cycle exceeds a threshold for a communication band of the network;
• and
• calculating a timing and an address to store the measurement data in the storage based on the data acquisition cycles and the groups resulting from the classification.
