Abstract

A distributed data server is a portable data server that is built by incorporating it with an embedded system. The distributed data server can receive outside data through an input unit, process the outside data via a control unit and then store the processed data to a storage unit. The server provides a network unit for the outside world to inquire about the processed data via the Internet. The server further offers a display unit to show a data message that is outputted from the control unit. In addition, the control unit can determine whether a plurality of states of data being written onto the storage unit are abnormal and, if so, output an abnormal signal as a warning. Hence, the distributed data server can reduce the huge systematic structure of the known distributed data server and construct any type of monitoring system flexibly.

Claims

1. A distributed data server comprises:

a control unit configured to be an embedded system;

a time control unit configured to provide time information required by the control unit;

an input unit configured to be a data input interface which is coupled to the control unit;

at least one storage unit configured for recording data processed by the control unit and for answering remote queries;

a display unit configured for displaying information provided by the control unit; and

a network unit configured to be coupled to the control unit for communicating over the Internet;

wherein the control unit is further configured for determining an abnormal situation of data recorded by the storage unit and further outputting an abnormal signal to show that abnormal situation by being incorporated with the network unit.

2. The distibuted data server according to claim 1, wherein the control unit further comprises:

a microcontroller configured to perform a single chip controller;

an electrically erasable and programmable ROM (EEPROM) configured for storing a firmware program, providing a monitoring mode and a time adjusting mode, reporting said modes for further executing, and incorporation with the microcontroller for operating; and

a switching device configured to be coupled to the microcontroller for selecting a executing mode for the firmware program.

3. The distributed data server according to claim 2, wherein the firmware program is a data server program.

4. The distributed data server according to claim 3, wherein the data server program includes a network server program.

5. The distributed data server according to claim 2, wherein the control unit further comprises:

a program recording unit configured to record a firmware program to the EEPROM.

6. The distributed data server according to claim 5, wherein the firmware program is a data server program.

7. The distributed data server according to claim 1, wherein the storage unit is one of a MultiMedia Card/RSMMC/MM, a SecureDigital Card/MiniSD/MicroSD, a Memory Stick/Memory Stick PRO/Memory Stick Duo/Memory Stick PRO Duo, a Type I/II Compact Flash Card, a MicroDrive, a SmartMedia Card/xD, a NAND Flash Memory or a Hard Disk Drive.

8. The distributed data server according to claim 1, wherein the display unit is a kind of Super Twisted Nematic (STN), a Color Super Twisted Nematic (CSTN), a Thin Film Transistor (TFT), a Thin Film Diode (TFD) or an Organic Light Emitting Diode (OLED).

9. The distributed data server according to claim 1, wherein the network unit is a wired or wireless network card.

10. The distributed data server according to claim 1, wherein the abnormal signal is an I/O signal.

11. The distributed data server according to claim 1, further comprising:

a power supply unit configured for providing power required by the control unit, the time control unit, the display unit, and the storage unit when operating.

12. The distributed data server according to claim 11, wherein the power supply unit further comprises:

a first power unit configured for providing power required by the control unit, the time control unit, and the storage unit when operating;

a second power unit configured to be an independent power source for the display unit; and

a third power unit configured for providing power required by the time control unit to keep the time control unit operating normally after the first power unit has been shut down.

13. The distributed data server according to claim 12, wherein the third power unit is a kind of carbon battery, alkaline battery, Li battery, pen battery, Nickel-Cadmium battery, Nickel-Metal Hydride battery and Li-ion battery.

14. An operating method for a distributed data server comprising:

receiving outside data via an input unit;

processing the data via a control unit;

storing the processed data in a plurality of available addresses of a storage unit, wherein the available addresses correspond to time information provided by a time control unit; and

determining whether the data is abnormal via the control unit, and outputting an abnormal signal if a determining result is true.

15. The operating method according to claim 14, further comprising transferring the outside data via the input unit to the control unit via a wired or wireless method.

16. The operating method according to claim 14, wherein the control unit comprises a data server program.

17. The operating method according to claim 16, wherein the data server program includes a network server program.

18. The operating method according to claim 14, wherein the outside data is received according to executive times of a network server which are set by the data server.

19. The operating method according to claim 14, wherein the processed data is stored according to time differences between unlocking monitoring modes, which are set by the data server.

20. The operating method according to claim 14, wherein the processed data is stored according to time points which are set by the data server.

21. The operating method according to claim 14, wherein the abnormal situation is a situation in which an environment temperature is higher than a predetermined temperature.

22. The operating method according to claim 14, wherein the abnormal situation is a situation in which no changeable activation in the monitoring data has occurred for a long term.

23. The operating method according to claim 14, wherein the abnormal signal is an I/O signal.

24. The operating method according to claim 14, further comprising logging in to the distributed data server via a network unit for inquiring about relative data in the storage unit.
