Embodiment
Please refer to Fig. 2, this is the circuit diagram of the first embodiment of the present invention, is the basic circuit structure figure of a control circuit 200.This control circuit 200 includes a load 101, a power supply 102, a three-way switch 210, a remote control module 220, a detection module 230 and a signal indicating module 240.
In this example, remote control module 220 has one and switches a unit 222 and a signal processing unit 221.Three-way switch 210 electrically connects mutually with switch unit 222, to set up two different power delivery path.And three-way switch 210 electrically connects power supply 102 again, the electric power that is provided with conduction power supply 102.222 of this switch units are electrically connected at load 101 and three-way switch 210.Power supply 102, three-way switch 210, switch unit 222 and load 101 by the mode of being connected in series to form series circuit.
This signal indicating module 240 sends a wireless signal, and 221 of signal processing units electrically connect switch unit 222 and accept this wireless signal.230 of detection modules electrically connect load 101 and remote control module 220 and accept wireless signal, and detection module 230 has a display unit 231.
Under the situation of Remote, the user utilizes signal indicating module 240 to send a wireless signal, and this wireless signal is received by signal processing unit 221 and detection module 230.Signal processing unit 221 moves switch unit 222 after receiving wireless signal.Switch unit 222 switches between these two different power delivery path, with the conducting path of change electric power, and then switch unit 222 and three-way switch 210 is switched between conducting state and off-state.
230 of detection modules detect the starts of switch units 222 when accepting wireless signal, and the start by switch unit 222 whether, judge whether normal operation of remote control module 220, and produce a determination information.And the actuator state of detection module 230 meeting detection loads 101, and produce a status information.At last, detection module 230 shows determination information and status information by display unit 231, and detection module 230 is to learn by determination information and status information whether remote control module 220 and load 101 damage to some extent.
To detect switch unit 222 starts undesired or not during start, remote control module 220 is inevitable in damaged condition when detection module 230.Otherwise when normally switching power delivery path as if switch unit 222, promptly representation signal processing unit 221 is normal starts, so detection module 230 judges that remote control modules are in the normal operation state.
Under remote control module 220 normal starts, when sending two wireless signals as if the user by signal indicating module 240, remote control module 220 carries out twice change action.If detection module 230 is measured load 101 when making two next states switching between opening and closing, represent that then load 101 runnings are normal.Otherwise, when load 101 can't be switched actuator state often or can't be switched actuator state fully, represent that promptly load 101 is in malfunction.
Generally speaking, detecting the modal mode of load 101 actuator states is to detect the start voltage of load 101 or make streaming current.Therefore on detection module 230, dispose a power supply detecting unit 232, this power supply detecting unit 232 continues to detect the voltage/current of load 101,230 of detection modules are judged the actuator state of load 101 by voltage/current numerical value change size, so as to producing status information.
This three-way switch 210 also has a switch key 211, under the situation of manually control, the user is by pressing switch key 211, three-way switch 210 is switched between these two power delivery path, conducting path with change electric power switches three-way switch 210 and switch unit 222 between two states such as a conducting state and an off-state.Control loop 200 formation path starts/open circuit so that load 101 can't obtain power supply 102 and interrupt so that load 101 obtains power supply 102.And power supply detecting unit 232 detects the variation of the voltage/current of load 101, and detection module 230 is actuator states of judging load 101 by voltage/current numerical value change size, so as to producing status information and being shown on the display unit 231.
Please refer to Fig. 3, it is the circuit structure diagram of the second embodiment of the present invention.The difference of second embodiment and first embodiment is that detection module 230 is when accepting wireless signal, detect the current state of load 101 earlier, and form a load information to export signal processing unit 221 to, and signal processing unit 221 is obtained this load information earlier when accepting wireless signal, and load information comes start switch unit 222 according to this.And power supply detecting unit 232 is to detect load 101 voltage/current at that time, and detection module 230 is judged the current state of load 101 again by voltage/current numerical value, to produce this load information.
Please refer to Fig. 4, it is the circuit structure diagram of the third embodiment of the present invention.The difference of the 3rd embodiment and first embodiment is that detection module 230 has a wireless letter in reply unit 233, and signal indicating module 240 includes letter receiving element 241 and letter in reply display unit 242.When detection module 230 produces determination informations/status information, be to transmit determination information/status information to the receiving element 241 of writing in reply by wireless letter in reply unit 233 with wireless transmissioning mode, signal indicating module 240 is to utilize letter in reply display unit 242 to show determination information/status information.
Please refer to Fig. 5, it is the circuit structure diagram of the fourth embodiment of the present invention.The difference of the 4th embodiment and first embodiment is that this control circuit 200 also includes a connectivity port 260 and a logging modle 250, and this logging modle 250 electrically connects detection module 230.Detection module stores this determination information/status information in logging modle 250 after producing determination information/status information.And connectivity port 260 electrically connects with logging modle 250 again, and this connectivity port 260 provides exterior display device 270 to electrically connect.Exterior display device 270 is to electrically connect by connectivity port 260 and logging modle 250, obtaining logging modle 250 stored determination information and status information, and determination information and status information is shown on the exterior display device 270.
In sum, this control circuit 200 is to avoid remote control module 220 to carry out wrong state to switch, and utilize detection module 230 can detect the actuator state of remote control module 220 and load 101, and show that this type of information is on display unit 231, or wireless output and being shown on the signal indicating module 240, more store this type of information in logging modle 250 and provide connectivity port 260 to electrically connect, make exterior display device 270 be obtained the stored information of logging modle 250 and show for exterior display device 270.Therefore the user can both know the operating state of load 101 whenever and wherever possible, and the start of selecting manual control or remote control mode to come control load 101.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of claim of the present invention.
