Abstract

A data transferring system and an object tracking system. The data transferring method includes generating messages based on the data, connecting the clients to the server, generating a plurality of event trigger thread instances, each of the instances being in communication with a corresponding one of the clients and sending the messages from the server to the clients through remote events by using the corresponding event trigger thread instance to control the communication between the server and the client.

Claims

1. A data transferring method for transferring data between a server and a plurality of clients, comprising:

generating messages based on the data;

connecting the clients to the server;

generating a plurality of event trigger thread instances, each of the instances being in communication with a corresponding one of the clients; and

sending the messages from the server to the clients through remote events by using the corresponding event trigger thread instance to control the communication between the server and the client.

2. The data transferring method of claim 1, wherein connecting the clients to the server includes registering a delegate method of the clients to a refresh event of the server.

3. The data transferring method of claim 2, wherein sending the messages from the server to the client includes sending the messages automatically upon triggering of the refresh event of the server.

4. The data transferring method of claim 1, wherein generating messages based on the data includes generating the messages based on the changes of the data within a certain time interval.

5. The data transferring method of claim 1, furthering comprising packing the messages prior to sending the messages from the server to the client and unpacking the messages after sending the messages from the server to the client.

6. The data transferring method of claim 5, further comprising compressing the message package prior to sending the messages from the server to the client and uncompressing the message package after sending the messages from the server to the client.

7. The data transferring method of claim 1, further comprising storing the messages in a cache before sending the messages from the server to the client.

8. A computer readable medium having computer readable program for operating on a computer for transferring data between a server and a plurality of clients, said program comprising instructions that cause the computer to perform the steps of:

generating messages based on the data;

connecting the clients to the server;

generating a plurality of event trigger thread instances, each of the instances being in communication with a corresponding one of the clients; and

sending the messages from the server to the clients through remote events by using the corresponding event trigger thread instance to control the communication between the server and the client.

9. The data transferring system of claim 8, wherein connecting the clients to the server includes registering a delegate method of the clients to a refresh event of the server.

10. The data transferring system of claim 9, wherein sending the messages from the server to the client includes sending the messages automatically upon triggering of the refresh event of the server.

11. The data transferring system of claim 8, wherein generating messages based on the data includes generating the messages based on the changes of the data within a certain time interval.

12. The data transferring system of claim 8, furthering comprising packing the messages prior to sending the messages from the server to the client and unpacking the messages after sending the messages from the server to the client.

13. The data transferring system of claim 12, further comprising compressing the message package prior to sending the messages from the server to the client and uncompressing the message package after sending the messages from the server to the client.

14. The data transferring system of claim 8, further comprising storing the messages in a cache before sending the messages from the server to the client.

15. An object tracking system for monitoring a plurality of objects, comprising:

a plurality of RFID tags each physically coupled with a corresponding object, for sending out wireless signals indicating the locations of the objects;

at least one RFID reader for receiving the wireless signals generated by the RFID tags and converting the signals into data indicating the locations of the objects; and

a data transferring system including;

a server for accessing the data generated by the RFID reader and generating messages based on the data;

a plurality of clients for receiving the messages generated by the server and monitoring the objects based on the messages; and

a microcontroller having data transferring software for transferring the data from the server the clients,

wherein the microcontroller having data transferring software generates a plurality of event trigger thread instances, each of the instances being in communication with a corresponding one of the clients, and sends the messages from the server to the clients through remote events by using the corresponding event trigger thread instance to control the communication between the server and the client.

16. The object tracking system of claim 15, wherein the microcontroller having data transferring software registers a delegate method of the clients to the server'"'"'s refresh event and sends the messages automatically upon triggering the refresh event of the server.

17. The object tracking system of claim 15, wherein generating messages based on the data includes generating the messages based on the changes of the data within a certain time interval.

18. The object tracking system of claim 15, furthering comprising packing the messages prior to sending the messages from the server to the client and unpacking the messages after sending the messages from the server to the client.

19. The data transferring system of claim 18, further comprising compressing the message package prior to sending the messages from the server to the client and uncompressing the message package after sending the messages from the server to the client.

20. The data transferring system of claim 15, further comprising storing the messages in a cache before sending the messages from the server to the client.
