BACKGROUND

1. Field of the Invention

The present invention relates to power supply systems, and particularly to a power supply system with wireless detection.

2. Description of Related Art

Power supply systems often require detecting devices for detecting their working status. Since power supply systems usually have very high (for example, 220V, 380V or more) working potentials, protecting apparatuses are widely used in the power supply systems to prevent high working potentials damaging the detecting devices. Most conventional protecting apparatuses are heavy and large in size, which may increase the size and weight of detecting devices, resulting in difficulties when assembling and conveying the detecting devices.

Therefore, in use, a detecting device of a power supply system is usually fixedly disposed at a predetermined position and connected by cables to the power supply system and manipulators (for example, operators or automatic processors). When the power supply system works, detection data of the power supply is recorded by the detecting device and transferred to manipulators by the cables. However, these cables may limit positions of the manipulators and increase cost.

Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENT

Referring toFIG. 1, a power supply system100according to an exemplary embodiment is provided. The power supply system100includes a detecting device10, a switch device20, a power supply device30and a wireless operating terminal50. The power supply device30includes a common power supply31and a standby power supply32, which are both connected to the switch device20. The switch device20is connected to at least one electric appliance60and can selectively switch on either one of the common power supply31and a standby power supply32to supply electric power to the electric appliance60. The detecting device10is connected to the switch device20and detects the working status of the power supply device30and the electric appliance60through the switch device20. The wireless operating terminal50can communicate with the detecting device10by conventional communication networks such as mobile phone networks, thereby obtaining detecting data of the power supply device30and the electric appliance60, and controlling the detecting device10.

Also referring toFIG. 2, the detecting device10includes a control module11, a wireless communication module12connected to the control module11, a regulator13, a battery14and a charger15. The control module11can be a conventional data processor, such as a computer, a single chip or a microprocessor, etc. The wireless communication module12can be a conventional transceiver such as an antenna, which is connected to the control module11and can communicate with the wireless operating terminal50. The charger15is connected to the control module11and the wireless communication module12. The regulator13and the battery14are both connected to the charger15.

The switch device20includes a first switch211, a second switch221and a third switch231. The first switch211and the second switch221are both connected to the third switch231. The common power supply31is connected to the first switch211, the standby power supply32is connected to the second switch221, and the electric appliance60is connected to the third switch231.

The switch device20further includes a first detector212connected to the first switch211, a second detector222connected to the second switch221, a third detector232connected to the third switch231and a relay24. The detectors212,222,232are all detecting circuits made of MID400 chip, which can generate relatively low porenitals (i.e., no more than 2V) for use as detecting data when relatively higher working electric potentials (e.g., 110V, 220V, 380V) are supplied to the switches211,221,231. The detectors212,222,232are also connected to the control module11. The second switch221is connected to the control module11through the relay24, thus the control module11can turn on or turn off the second switch221by the relay24. The third switch231is connected to the regulator13.

The wireless operating terminal50can be a portable terminal or an immobile terminal installed at a predetermined position. The wireless operating terminal50can receive and send wireless electronic signals, display data, and edit instruction for controlling the power supply system100. As examples, the wireless operating terminal50can be a mobile phone, a personal digital assistant (PDA), a laptop computer, etc.

When the power supply system100is started, the first switch211and the third switch231are turned on and then the common power supply31supplies electric power to the electric appliance60. During use of the appliance60, the first detector212and the third detector232respectively detect real time working electric potential of the first switch211and the third switch231, and generate relative low detecting output electric potentials according to the working electric potentials. The voltages of the detecting output potentials are sent to the control module11to be recorded as detecting data of the common power supply31and the electric appliance60. The control module11determines if the working electric potentials are in acceptable ranges according to the detecting data, and can send the detecting data to the wireless operating terminal50using the wireless communication module12. Thus, manipulators (operators or processors) can obtain real time detecting data from the wireless operating terminal50.

If the common power supply31malfunctions, the control module11can detect the malfunctions of the common power supply31according to the detecting data generated by the first detector212. Thus, the control module11automatically turns on the second switch221by the relay24such that the standby power supply32replaces the common power supply31to supply electric power to the electric appliance60through the second switch221and the third switch231. The second detector222detects real time working electric potential of the second switch221, thereby generating detecting data of the standby power supply32and sending the detecting data to the control module11to record. The control module11also sends the detecting data to the wireless operating terminal50. When the common power supply31is repaired, the control module11detects the restored electric potential of the common power supply31and the first switch211by the first detector211. The control module11automatically turns off the second switch221by the relay24, and the common power supply31resumes to supply electric power to the electric appliance60. Additionally, if the standby power supply32also malfunctions, the control module11can detect the error according to the detecting data generated by the second detector222, thus the control module11can automatically turn off the second switch221until the common power supply31or the standby power supply32is repaired.

The control module11can also be connected to the first switch211and the third switch231using relays (not shown), thus the control module11can automatically turn on or turn off the first switch211and the third switch231. Further, the manipulators can edit instruction by the wireless operating terminal50and send the instruction to the control module11by the wireless operating terminal50and the wireless communication module12, thereby controlling the switches211/221/231via the control module11. Thus, the power supply system100can be manually remotely operated. An ammeter70can also be connected between the common power supply31and the first switch211to directly display the common working electric potential of the power supply system100.

During use, power for operating the control module11and the wireless communication module12can be supplied by the charger15and the battery14. The working electric potential supplied by the common power supply31or the standby power supply32can also be outputted from the third switch231to the regulator13to be regulated into an acceptable range to be used by the control module11and the wireless communication module12, and then is supplied to the control module11and the wireless communication module12through the charger15.

In the exemplary power supply system100, the detecting data can be sent to the wireless operating terminal50by typical communication networks, thus, the manipulators can monitor the data anytime and anywhere via the wireless communication terminal50. The manipulators can further remotely control the power supply system100using the wireless communication terminal50. Additionally, the power supply system100can automatically switch and detect the two power supplies (31and32) in a working process, such that the electric appliance connected thereto gets durative electric power.
