Abstract

Provided is a trace data recording system, including: a trace data generator configured to generate trace data of equipment relating to motor control; a trace data transmitter configured to transmit the generated trace data to a server via a network; and a trace data recorder configured to record the transmitted trace data in the server.

First claim

What is claimed is:

1. A trace data recording system, comprising:
a motor controller configured to control at least one motor;
a user terminal operated by a user;
an analyst terminal operated by an analyst; and
a cloud server configured to manage information of users;
wherein the motor controller is configured to generate trace data relating to motor control of the at least one motor;
wherein the user terminal is configured to transmit the generated trace data to the cloud server via a network when the user performs an upload operation; and
wherein the cloud server is configured to:
record the transmitted trace data associated with a serial number of the motor controller and user information of the user who performs the upload operation in the cloud server;
prohibit the analyst from accessing to the trace data;
receive an analysis requirement of the trace data with the serial number and the user information from the user terminal; and
permit the analyst to access to the trace data that is associated with the received serial number and the user information when the analysis requirement is received.

2. The trace data recording system according to claim 1 ,
wherein the motor controller is configured to generate an alarm based on an operating state of the motor controller, and
wherein the motor controller automatically generates the trace data of the motor controller in a case where an alarm has been generated.

3. The trace data recording system according to claim 2 ,
wherein the user terminal is configured to transmit to the cloud server information identifying a type of generated alarm,
wherein the cloud server is configured to acquire the transmitted alarm type, and
wherein the cloud server links the transmitted trace data with the type of generated alarm, and records the linked trace data in the cloud server.

4. The trace data recording system according to claim 2 , wherein the cloud server automatically transmits, in a case where an alarm has been generated, the generated trace data to the server.

5. The trace data recording system according to claim 2 ,
wherein the cloud server is configured to transmit to the analyst terminal, among a plurality of trace targets relating to the motor controller, trace data of a trace target corresponding to a type of generated alarm.

6. The trace data recording system according to claim 2 ,
wherein the cloud server is configured to transmit to an analyst's terminal trace data for a period corresponding to a type of generated alarm.

7. The trace data recording system according to claim 1 ,
wherein the user terminal transmits, in a case where the analysis request is transmitted, the trace data to the cloud server.

8. The trace data recording system according to claim 1 ,
wherein the cloud server is configured to acquire user information for identifying a user, and
wherein the cloud server links the transmitted trace data with the acquired user information, and records the linked trace data.

9. The trace data recording system according to claim 1 ,
wherein the cloud server is configured to acquire individual identification information on the motor controller, and
wherein the cloud server links the transmitted trace data with the acquired individual identification information, and records the linked trace data.

10. The trace data recording system according to claim 1 ,
wherein the motor controller operates based on setting information, and
wherein the cloud server is configured to acquire the setting information on the motor controller; and
the cloud server is configured to transmit to the analyst terminal the acquired setting information together with the trace data registered in the cloud server.

11. A trace data recording server configured to:
acquire, from a user terminal configured to transmit trace data relating to motor control of at least one motor that is controlled by a motor controller to the trace data recording server, the trace data via a network;
record the acquired trace data associated with a serial number of the motor controller and user information of a user who performs an upload operation in the trace data recording server;
prohibit an analyst who operates an analyst terminal from accessing to the trace data;
receive an analysis requirement of the trace data with the serial number and the user information from the user terminal; and
permit the analyst to access to the trace data that is associated with the received serial number and the user information when the analysis requirement is received.

12. A trace data recording method, comprising:
generating trace data relating to motor control of at least one motor that is controlled by a motor controller;
transmitting the generated trace data to a cloud server via a network when a user performs an upload operation;
recording the transmitted trace data associated with a serial number of the motor controller and user information of the user who performs the unload operation in the cloud server;
prohibiting an analyst who operates an analyst terminal from accessing to the trace data;
receiving an analysis requirement of the trace data with the serial number and the user information from the user terminal; and
permitting the analyst to access to the trace data that is associated with the received serial number and the user information when the analysis requirement is received.

13. A non-transitory computer-readable information storage medium having stored thereon a program for causing a computer to:
acquire, from a user terminal configured to transmit trace data relating to motor control of at least one motor that is controlled by a motor controller to the computer, the trace data via a network;
record the acquired trace data associated with a serial number of the motor controller and user information of a user who performs an upload operation in the computer;
prohibit an analyst who operates an analyst terminal from accessing to the trace data;
receive an analysis requirement of the trace data with the serial number and the user information from the user terminal; and
permit the analyst to access to the trace data that is associated with the received serial number and the user information when the analysis requirement is received.
