[0057] See also Figures 5 to 11 The second embodiment of the utility model provides a remote control circuit based on the first embodiment, the remote control circuit at least includes a control module, a timer circuit, a sensor circuit and an infrared circuit. The control module may include a clock circuit.

[0058] Reference Figures 5 and 6In this embodiment, the sensing circuit is implemented by a passive infrared detection probe, and the first detection unit and the second detection unit are respectively the first detection probe PIR1 and the second detection probe PIR2. The first detection probe PIR1 and the second detection probe PIR2 are respectively used to sense the first part and the second part in the space, wherein the first part and the second part may partially overlap. Furthermore, there is a square lens between the first detection probe PIR1 and the second detection probe PIR2, and the other is a circular lens. The double-lens design can increase the sensitivity of the front detection and reduce the detection blind spot. After matching the square lens, the detection distance can reach 10 meters, and the detection angle range can reach 0 to 100 degrees; after matching the circular lens, the detection distance can reach five meters, and the detection angle range can reach 0 to 120 degrees. Taking the installation direction of the remote control circuit facing the space as the reference direction, any one of the first detection probe PIR1 and the second detection probe PIR2 can be installed in a detection direction consistent with the reference direction, so as to enable sensitive detection in the left and right directions, and the other can be installed in a detection direction that forms a horizontal angle of 45 degrees with the reference direction, so as to enable sensitive detection in the front and back directions. This setting allows the first detection probe PIR1 and the second detection probe PIR2 to be placed in coordination with each other, thereby improving the ability to capture human activity signals moving in space.

[0059] The passive infrared sensor detection probe can be two pyroelectric elements connected in series or in parallel, and the two polarization directions are just opposite. The environmental background radiation has almost the same effect on the two pyroelectric elements, causing the pyroelectric effects to cancel each other out, so the detector has no signal output. Once an intruder enters the detection area, the infrared radiation of the human body is focused through a partial mirror and thus received by the pyroelectric element. However, the heat received by the two pyroelectric elements is different, and the pyroelectricity is also different, which cannot be offset, and an alarm is generated after signal processing.

[0060] The sensing circuit is implemented using dual passive infrared detection probes, so its peripheral circuits need to be set up accordingly so that the infrared signals detected by the first detection probe PIR1 and the second detection probe PIR2 can be processed into human activity signals. In the first solution, the output ends of the first detection probe PIR1 and the second detection probe PIR2 can be connected, grounded, and connected to the input end of the control module, so that the signal input to the input end of the control module can be the difference between the first infrared signal and the second infrared signal. The difference reflects the difference in the data sensed by the first detection probe PIR1 and the second detection probe PIR2, indicating that there may be human activity in the space. Specifically, Figure 5 In the embodiment, the output ends of the first detection probe PIR1 and the second detection probe PIR2 are grounded and then connected to the first pin p24 of the control chip U1.

[0061] See also Figure 7 In the second solution, the output ends of the first detection probe PIR1 and the second detection probe PIR2 can be connected to the first pin and the second pin of the signal processing unit respectively, so that the first infrared signal and the second infrared signal are input into the signal processing unit as differential signals, so that the signal processing unit outputs the difference between the first infrared signal and the second infrared signal, and the difference between the first infrared signal and the second infrared signal is input into the control module. Figure 5 In the embodiment, the output end of the first detection probe PIR1 is connected to the PA7 pin of the signal processing chip U2, the output end of the second detection probe PIR2 is connected to the PA6 pin of the signal processing chip U2, and the PA3 / TM2PWM pin of the signal processing chip U2 is connected to the P24 pin of the control chip U1.

[0062] The first and second schemes mentioned above can be integrated together. It is only necessary to set two parallel branches at the output ends of the first detection probe PIR1 and the second detection probe PIR2, wherein a forward-set diode is added to the branch directly connected to the control module, and the other branch is directly connected to the signal processing unit. Since the branch with a small resistance is always turned on first, when there is a signal processing unit, the first infrared signal and the second infrared signal are always sent to the signal processing unit first. In the case that the signal processing unit is damaged or not installed, the signal can be directly sent to the control module for processing through the conduction of the diode. Some PIR sensors have a control chip inside, and some sensors need to be connected to an external control chip. In this way, the processed sensor circuit has high compatibility and can be directly adapted to two hardware circuits with and without a signal processing unit in a modular setting.

[0063] In this embodiment, the infrared circuit is used to send infrared signals so that the remote control can transmit signals to the controlled device. Usually, the infrared circuit can also be used to receive infrared signals so that the remote control can confirm whether the signal transmission is successfully completed through the feedback of the controlled device. The infrared control unit is the infrared remote control chip U4, so see Figure 8 The infrared circuit includes an infrared receiving tube and a plurality of infrared transmitting tubes connected in parallel, and an infrared remote control chip U4 for controlling the infrared receiving tube and the infrared transmitting tube. The IR pin of the infrared remote control chip U4 is connected to the first infrared transmitting tube D5, the second infrared transmitting tube D6, the third infrared transmitting tube D7, the fourth infrared transmitting tube D8 and the fifth infrared transmitting tube D9 connected in parallel, and the IR pin of the infrared remote control chip U4 is simultaneously connected to the output end of the infrared receiving dedicated head IR1 through the third resistor R16, and the infrared receiving dedicated head IR1 is provided with an infrared receiving tube.

[0064] Further, see Figures 9 to 12The embodiment also includes an interactive circuit for interaction, which includes a setting unit and a dial unit for inputting commands, and also includes a display unit for displaying information. The setting unit includes a plurality of switches, which are connected in parallel to the AD-KEY pin of the control chip U1, wherein, see Fig. 9 The first switch K1 is a control button, the second switch K2 is a function selection button, the third switch K3 is a delay setting button, the fourth switch K4 is a value-added signal input button, and the fifth switch K5 is a value-reduced signal input button. Fig.10 The code unit includes a code switch SW1, and the three contacts of the code switch SW1 are respectively connected to the power supply, the control chip U1 and the ground terminal. The code switch SW1 can control the power-on state of the control chip U1, and thus control its working state. Figure 11 to Figure 12 The display unit of this embodiment can be an LCD screen with an LED backlight circuit, which is used to display the working state and related working parameters of the remote control circuit. The interactive circuit can also include a voice unit.

[0065] Furthermore, the sensing circuit in this embodiment may also include at least one of a humidity sensing unit, a temperature sensing unit and a light sensing unit, so as to adjust the operation of the controlled device by factors such as humidity, temperature and light in the space.

[0066] Through the remote control circuit disclosed in the first embodiment or the second embodiment above, the circuit can be used to monitor human activities in a space, and use this as a basis for triggering the remote control circuit to send a control signal to the controlled device, thereby realizing multiple control schemes:

[0067] First control scheme: After the sensor circuit obtains the human activity signal, the control module generates the first control signal and sends it to the controlled device through the infrared circuit to refresh the shutdown time of the controlled device. For example, when the human activity signal is detected in the space, the control module generates a shutdown signal to be sent after 30 minutes, which covers the shutdown signal originally sent after 10 minutes, so that the controlled device is running when there are people in the space and the controlled device is turned off when there are no people in the space.

[0068] Second control scheme: Combine the timing circuit and the internal clock circuit in the control module to set a fixed time node every day to turn on or off the controlled device. For example, send a shutdown signal to the controlled device at 9 am every day, or send a startup signal to the controlled device at 10 pm every day.

[0069] The third control scheme: Combine the timing circuit, the sensor circuit and the internal clock circuit in the control module, set the first fixed time node of the day to send a power-on signal to the controlled device, and the second fixed time node of the day to send a power-off signal to the controlled device, so as to set the fixed working time of the controlled device, and detect the human activity signal in the space outside the fixed working time of the controlled device. If human activity is detected, the control module generates a first control signal and sends it to the controlled device through the infrared circuit to refresh the power-off time of the controlled device. For example, the controlled device is set to turn on at 9 pm every day and turn off at 6 am the next day. At this time, the fixed working time of the controlled device is from 9 pm to 6 am. When the preparation time of the first control signal is 30 minutes, starting from 6:31 am, after receiving the human activity signal, the control module generates a power-off signal that is sent 30 minutes later, and the original power-off signal is overwritten to postpone the power-off time node of the controlled device.

[0070] Combined with the sensing circuit, interactive circuit and control module, the display unit is triggered to display content when there is a human activity signal in the space; the interactive circuit can set the specific working parameters of the remote control circuit. For example, the control button is used to enter the disabled mode, and other button functions become invalid after being pressed; the function selection button is used to enter the setting mode, the plus signal input button and the minus signal input button are used to coordinate the setting of time nodes and the size of temperature, humidity, brightness and volume, etc., and the delay setting button is used to select the control scheme.

[0071] The above-mentioned preparation time can be infinitely adjusted or set by gear, including 1 minute, 15 minutes, 30 minutes, 60 minutes, 90 minutes, 120 minutes and 150 minutes. The above-mentioned display circuit can also be used to display the humidity, temperature, setting parameters of the controlled equipment, current time, currently selected control scheme, current working status, preset startup time node and preset shutdown time node in the space.

[0072] The third embodiment of the utility model discloses a remote controller, comprising the remote controller circuit disclosed in any one of the above embodiments, wherein the remote controller circuit is arranged in a housing. The remote controller can be arranged to be wall-mounted, which is convenient for unified installation and avoids loss.

[0073] Furthermore, in the remote controller disclosed in this embodiment, the remote controller circuit may have multiple sensing circuits, which are divided into sub-circuits and dispersedly installed in multiple areas in the space to better acquire human activity signals in the space. These sub-circuits can send human activity signals to the control module via other wireless or wired communication methods such as Bluetooth communication or infrared communication.
