DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
Exemplary Embodiment of Electronic Apparatus
Referring to FIG. 1, FIG. 1 is a block diagram of an electronic apparatus according to an exemplary embodiment of the present disclosure. The electronic apparatus 1 comprises an offline setup recording device 2, a controller 3, and an electronic chip 4. The offline setup recording device 2, the controller 3, and the electronic chip 4 are all electrically coupled to a ground GND and a power supply VDD. The offline setup recording device 2 is electrically coupled to the controller 3, and the electronic chip 4 is also electrically coupled to the controller 3.
When the electronic apparatus 1 is offline (i.e. the electronic apparatus 1 is not connected to the power supply VDD, or the power supply stops to provide the power), the offline setup recording device 2 allows the user configuring the setup of the electronic apparatus 1, and stores the setup.
The difference between the offline setup recording device 2 and the conventional offline setup recording device implemented by the dip switch or the jumper is that the conventional offline setup recording device cannot be automatically reset to the initial state after the electronic apparatus read the setup, but the offline setup recording device 2 can be automatically reset to the initial state after the electronic apparatus 1 read the setup.
In other words, when the electronic apparatus 1 is online again (i.e. the power supply provides the power again), if the user wants the electronic apparatus 1 to be reset to the initial state, the user does not need to use the hand thereof to adjust the dip switch or the jumper. Furthermore, after the setup stored in the offline setup recording device 2 is readout, the setup is back to be present of the initial state.
The setup stored in the offline setup recording device 2 and configured by the user when the electronic apparatus 1 is offline may be represented by at least a storage voltage signal. For example, in FIG. 1, the setup may be represented by the two storage voltage signals. When the electronic apparatus 1 is online again, the storage voltage signals used to represent the setup are read out, and the offline setup recording device 2 outputs the read voltage signals VR1 and VR2 to the controller 3.
It is noted that, the read voltage signals VR1 and VR2 may be the digital versions, the inverted digital versions, or the amplified analog versions of the two storage voltage signals, or the read voltage signals VR1 and VR2 may be two storage voltage signals used to represent the setup. Generally, to simplify the design complexity of the electronic circuit, the read voltage signals VR1 and VR2 may be the inverted digital versions of the two storage voltage signals.
The controller 3 receives and decodes the read voltage signals VR1 and VR2 to obtain the state setup signal STATE_SIG, wherein the state setup signal STATE_SIG is used to directly represent the setup. The electronic chip 4 receives the state setup signal STATE_SIG, and continues to be configured according to the state setup signal STATE_SIG representing the setup, so as to execute a new following setup work. To put it concretely, the state setup signal STATE_SIG is used to represent whether the electronic apparatus 1 is configured when the electronic apparatus 1 is offline, and used to represent the setup configured when the electronic apparatus 1 is offline.
For example, when the read voltage signals VR1 and VR2 are both 5 volts, the state setup signal STATE_SIG is 0 and represents that the user does not configure the setup of the electronic apparatus 1 when the electronic apparatus 1 is offline, i.e. the setup stored in the offline setup recording device 2 is present of the initial state. Accordingly, the electronic apparatus 1 is not to be configured and maintained without any change. For example, if the read voltage signals VR1 and VR2 are respectively 5 volts and 0 volt, the state setup signal STATE_SIG is 1 and represents that the user configures the setup of the electronic apparatus 1 when the electronic apparatus 1 is offline, i.e. the setup stored in the offline setup recording device 2 is not present of the initial state. Accordingly, the electronic apparatus 1 is to be configured according to the setup which the state setup signal STATE_SIG is 1, so as to execute a new following setup work.
In addition, after the read time is reached (i.e. the read voltage signals VR1 and VR2 are obtained), the controller 3 outputs the discharge control signal COM to discharge the two storage voltage signals stored in the offline setup recording device 2. Generally, the controller 3 controls the offline setup recording device 2 discharges the two storage voltage signals, such that the two storage voltage signals are substantially reduced to the ground GND. However, in some special cases, the controller 3 further provides two reference voltages VREF1 and VREF2 to the offline setup recording device 2, such that the two storage voltage signals are substantially reduced to the reference voltages VREF1 and VREF2 respectively. To put it concretely, the discharging devices 206 and 210 are usually implemented by the NPN transistors, the PNP transistors or the Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs), such that the storage voltage signals are reduced to VREF1+VCE (or VREF1+VDS) and VREF2+VCE (or VREF2+VDS) respectively.
Though the exemplary example of FIG. 1 has two read voltage signals VR1 and VR2, the present disclosure is not limited thereto. The number of the read voltage signal is not used to limit the present disclosure. In addition, the controller 3 may not discharge the two storage voltage signals in the offline setup recording device 2, and may not provide the reference voltages VREF1 and VREF2 to the offline setup recording device 2, either. Moreover the electronic apparatus 1 in FIG. 1 may be the ZigBee control lamp, hard disk, compact disc reader, or motherboard, and the electronic chip 4 may correspondingly be the ZigBee light emitting diode chip, hard disk chip, compact disc reader chip, or motherboard chip.
Exemplary Embodiment of Offline Setup Recording Device
Referring to FIG. 2, FIG. 2 is a block diagram of an offline setup recording device according to an exemplary embodiment of the present disclosure. The offline setup recording device 2 comprises a unidirectional conduction unit 201, a total energy storage unit 202, at least an automatically recovering switch 203, 207, at least a state energy storage unit 204, 208, at least a reading unit 205, 209, and at least a discharging device 206, 210.
A first end of the unidirectional conduction unit 201 is electrically coupled to the power supply VDD, and a second end of the unidirectional conduction unit 201 is electrically coupled to a first end of the total energy storage unit 202. The first end of the total energy storage unit 202 is electrically coupled to first ends of the automatically recovering switches 203 and 207, and a second end of the total energy storage unit 202 is electrically coupled to the ground GND. Second ends of the automatically recovering switches 203 and 207 are electrically coupled to first ends of the state energy storage units 204 and 208 respectively. The first end of the state energy storage unit 204 is electrically coupled to first ends of the reading unit 205 and the discharging device 206, the first end of the state energy storage unit 208 is electrically coupled to first ends of the reading unit 209 and the discharging device 210, and second ends of the state energy storage units 204 and 208 are electrically coupled to the ground GND. Second ends of the reading units 205 and 209 output the read voltage signals VR1 and VR2 respectively, and third ends of the reading units 205 and 209 are electrically coupled to the power supply VDD. Control ends of the discharging devices 206 and 210 receive the discharge control signal COM, and second ends of the discharging devices 206 and 210 receive the reference voltages VREF1 and VREF2 respectively.
It is noted that though the exemplary embodiment of FIG. 2 has two automatically recovering switches 203, 207, two state energy storage units 204, 208, two reading units 205, 209, and two discharging devices 206, 210, the present disclosure is not limited thereto. In other words, the offline setup recording device 2 may merely have one automatically recovering switch 203, one reading unit 205, one state energy storage unit 204, and one discharging device 206, or the offline setup recording device 2 may have at least three automatically recovering switches, at least three state energy storage units, at least three reading units, and at least three discharging devices.
The unidirectional conduction unit 201 is conductive when the electronic apparatus 1 is online, and thus when electronic apparatus 1 is online, the power supply VDD charges the total energy storage unit 202. When the electronic apparatus 1 is offline, due to the unidirectional conduction of the unidirectional conduction unit 201, the total voltage stored in the total energy storage unit 202 is disable to discharge via the unidirectional conduction unit 201, such that the total voltage can be stored temporally. When the total energy storage unit 202 is implemented by the ceramics capacitor, the total voltage may be stored for two days.
The first and second ends of automatically recovering switch 203 (or 207) are conductive if the user touches, presses, or pulls the automatically recovering switch 203 (or 207) when the electronic apparatus 1 is offline. After the automatically recovering switch 203 (or 207) is touched, pressed, or pulled by the user (i.e. the automatically recovering switch 203 is not touched, pressed, or pulled now), the first and second ends of automatically recovering switch 203 (or 207) are back to open. In other words, the automatically recovering switch 203 (or 207) is conductive merely when being touched, pressed, or pulled by the user, and then is automatically back to open. Thus the automatically recovering switch 203 (or 207) may be a button switch, sensitive switch, touching switch, or sliding switch.
When the first and second ends of automatically recovering switch 203 are conductive, the total energy storage unit 202 charges the state energy storage unit 204, and thus the state energy storage unit stores the storage voltage signal VS1. In the similar manner, when the first and second ends of the automatically recovering switch 207 are conductive, the total energy storage unit 202 charges the state energy storage unit 208, and thus the state energy storage unit 208 stores the storage voltage signal VS2.
When the electronic apparatus 1 is online again, the reading units 205 and 209 read out the storage voltage signals VS 1 and VS2 respectively, so as to output the read voltage signals VR1 and VR2. Each of the reading units 205 and 209 may comprise at least one of an amplifier, a buffer, and an analog-to-digital converter with at least bit. It is noted that the reading units 205 and 209 cannot read out the storage voltage signals VS1 and VS2 when the electronic apparatus 1 is offline, such that the state energy storage units 204 and 208 can temporally store the storage voltage signals VS1 and VS2 respectively. The state energy storage units 204 and 208 are implemented by the ceramics capacitors, the storage voltage signals VS1 and VS2 may be stored for two days.
The discharging devices 206 and 210 are controlled by the discharge control signal COM. When the read time is reached (i.e. the read voltage signals VR1 and VR2 are obtained), the controller 3 controls the discharging devices 206 and 210 provide the discharging path, such that the storage voltage signals VS1 and VS2 respectively stored in the state energy storage units 204 and 208 are discharged, and the storage voltage signals VS1 and VS2 are reduced to the reference voltages VREF1 and VREF2 respectively. As mentioned above, the controller 3 may not provide the reference voltages VREF1 and VREF2, and the second ends of the discharging devices 206 and 210 may be electrically coupled to the ground GND directly.
Exemplary Embodiment of Controller
Referring to FIG. 3, FIG. 3 is a block diagram of a controller according to an exemplary embodiment of the present disclosure. The controller 3 may be the independent chip not included in the electronic chip 4 of the electronic apparatus 1, or may be integrated and included in the electronic chip 4. The controller 3 comprises a state decoding device 31, a counter 32, and a reference voltage provider 33. The controller 3 starts to operate when the electronic apparatus is online. It is noted that the controller 3 in FIG. 3 is merely an exemplary embodiment of the present disclosure, and the present disclosure is not limited thereto.
The state decoding device 31 receives and decodes the read voltage signals VR1 and VR2 to generate the state setup signal STATE_SIG. The counter 32 starts to count when the electronic apparatus 1 is online. When the read time counted by the counter 32 is reached, the counter 32 outputs the discharge control signal COM. The reference voltage provider 33 receives the power from the power supply VDD, and provides the reference voltages VREF1 and VREF2.

If the discharging devices 206′ and 210′ are implemented by the NPN transistors Q1 and Q2 respectively, the storage voltage signals VS1 and VS2 respectively stored in the capacitors C1 and C2 are reduced to VREF1+VCE and VREF2+VCE when the NPN transistors Q1 and Q2 are controlled to be turned on. Generally, the current voltage VCE between the collector and the emitter is the saturation voltage between the collector and the emitter, i.e. VCE is 0.2 volts.
The reading units 205′ and 209′ are implemented by the inverters, wherein the inverter of the reading unit 205′ comprises a MOSFET M1 and a resistor R1, and the inverter of the reading unit 209′ comprises a MOSFET M2 and a resistor R2. The gates of the MOSFETs M1 and M2 are electrically coupled to the capacitors C1 and C2 respectively, the drains of the MOSFETs M1 and M2 are electrically coupled to the resistors R1 and R2 respectively, and the sources of the MOSFETs M1 and M2 are electrically coupled to the ground GND. The drains of the MOSFETs M1 and M2 output the read voltage signals VR1 and VR2 respectively.
When the user touches the touching switch SW1, the storage voltage signal VS1 stored in the capacitor C1 is increased, and thus the reading unit 205′ outputs the read voltage signal VR1 with the voltage being present of the logical 0. In the similar manner, when the user touches the touching switch SW2, the storage voltage signal VS2 stored in the capacitor C2 is increased, and thus the reading unit 210′ outputs the read voltage signal VR2 with the voltage being present of the logical 0.

The bases of PNP transistors Q1′ and Q2′ receive the discharge control signal COM, the emitter of the PNP transistors Q1′ and Q2′ are electrically coupled to the capacitors C1 and C2 respectively, and the collectors of the PNP transistors Q1′ and Q2′ receive the reference voltages VREF1 and VREF2 respectively.
It is noted that the discharge control signal COM generated by the controller in FIG. 4B is low, but the discharge control signal COM generated by the controller in FIG. 4A is high.

Referring to FIG. 4C, FIG. 4C is a detailed circuit diagram of an offline setup recording device according to another one exemplary embodiment of the present disclosure.

The other difference between the offline setup recording device 2′′′ in FIG. 4C and the offline setup recording device 2′ in FIG. 4A is that the reading units 205′′ and 209′′ are implemented by the buffers to replace the inverters.
In FIG. 4C, one end of the resistor R3 is electrically coupled to the gate of the MOSFET M3, and the other end is electrically coupled to the ground GND. The gate of the MOSFET M3 receives the discharge control signal COM, and is electrically coupled to one end of the resistor R3. The drain of the MOSFET M3 is electrically coupled to one end of the capacitor C1, and the source of the MOSFET M3 receives the reference voltage VREF1. One end of the resistor R4 is electrically coupled to the gate of the MOSFET M4, and the other end of the resistor R4 is electrically coupled to the ground GND. The gate of the MOSFET M4 receives the discharge control signal COM, and is electrically coupled to one end of the resistor R3. The drain of the MOSFET M4 is electrically coupled to one end of the capacitor C1, and the source of the MOSFET M4 receives the reference voltage VREF2.
In the exemplary embodiment, the storage voltage signals VS1 and VS2 respectively stored in the capacitors C1 and C2 are reduced to VREF1+VDS and VREF2+VDS respectively when the MOSFETs M3 and M4 are controlled to be turned on. Generally, the current voltage VDS between the drain and the source is the saturation voltage between the drain and the source.
The reading unit 205′′ is a buffer, and comprises a MOSFET M1 and a resistor R1. The gate of the MOSFET M1 is electrically coupled to one end of the capacitor C1, the drain of the MOSFET M1 is electrically coupled to the power supply VDD, and the source of the MOSFET M1 is electrically coupled to one end of the resistor R1. The other end of the resistor R1 is electrically coupled to the ground GND, the voltage between the two ends of the resistor R1 is the read voltage signal VR1.

In the exemplary embodiment, when the user touches touching switch SW1, the storage voltage signal VS1 stored in the capacitor C1 is increased, and thus the reading unit 205′′ outputs the read voltage signal VR1 with the voltage being present of the logical 1. In the similar manner, when the user touches the touching switch SW2, the storage voltage signal VS2 stored in the capacitor C2 is increased, and thus the reading unit 210′′ outputs the read voltage signal VR2 with the voltage being present of the logical 1.

The ZigBee control lamp 51 (coordinator) may assign the network addresses and network parameters to the ZigBee control lamp 52 ̃55 (clients).
