Abstract

Provided is a radio formed to be capable of performing wireless communication with sensors, and configured to be connected, through one communication port via wired communication, to a slave control apparatus configured to be communicably connected to a master control apparatus with a predetermined communication method. The radio generates one communication packet formed with the predetermined communication method and transmitted from the radio to the slave control apparatus, such that pieces of measured data measured by the sensors are included in the one communication packet in accordance with a predetermined order in which the slave control apparatus or the master control apparatus can determine which sensor measured which piece of the measured data of the sensors, and the radio transmits the generated one communication packet to the slave control apparatus via wired communication.

First claim

The invention claimed is:

1. A system comprising:
a radio;
a slave control apparatus; and
a master control apparatus, wherein
the radio comprises a processor configured with a program to perform operations comprising:
operation as a connection unit that connects the radio to the slave control apparatus such that wired communication can be performed through one communication port among a plurality of communication ports provided in the slave control apparatus;
operation as a storage unit that:
receives, via wireless communication, a plurality of pieces of measured data that were respectively measured by a plurality of sensors, and
stores the plurality of pieces of measured data;

operation as a generation unit that:
generates one communication packet comprising the plurality of pieces of measured data, and correlation information that indicates a predetermined order in which each one of the plurality of pieces of measured data are superimposed in the one communication packet, to enable:
the slave control apparatus, communicably coupled to the master control apparatus with a predetermined communication method, to determine, based on receiving the correlation information of the one communication packet, which sensor of the plurality of sensors measured each one of the plurality of pieces of measured data and to generate updated correlation information, wherein the updated correlation information comprises a memory address corresponding to a location in a memory where each one of the plurality of pieces of measured data is stored, and
the master control apparatus, based on the updated correlation information generated by the slave control apparatus, to determine which sensor of the plurality of sensors measured each one of the plurality of pieces of measured data; and

operation as a transmission unit that transmits the one communication packet generated by the generation unit to the slave control apparatus via the wired communication; and

the slave control apparatus comprises a processor configured with a program to perform operations comprising:
operation as a reception unit that receives the one communication packet; and
operation as a dividing unit that performs division processing on each of the plurality pieces of measured data that are included in the one communication packet received by the reception unit, based on the predetermined order, into a state in which each of the plurality of pieces of measured data is linked with a corresponding one of the plurality of sensors.

2. The system according to claim 1 wherein the processor of the radio is further configured with the program to perform operations comprising:
operation as an identification information collection unit that collects pieces of identification information for respectively identifying individual sensors from the plurality of sensors, when the radio is initially connected to the plurality of sensors via the wireless communication; and
operation as a notification unit that notifies the slave control apparatus or the master control apparatus of the pieces of identification information of the plurality of sensors collected by the identification information collection unit and the correlation information, when the radio is initially connected to the slave control apparatus via the wired communication.

3. The system according to claim 2 , wherein the slave control apparatus transmits, to the master control apparatus, the pieces of measured data included in the one communication packet transmitted from the transmission unit, in a state in which each piece of the measured data is linked with a corresponding one of the plurality of sensors, based on the updated correlation information.

4. The system according to claim 1 ,
wherein the slave control apparatus is connected to the master control apparatus such that wired communication can be performed through a second communication port that is different from the one communication port among the plurality of communication ports provided in the slave control apparatus.

5. The system according to claim 1 ,
wherein the radio is integrally formed with the slave control apparatus.
