TECHNICAL FIELD

[0001] The utility model relates to the field of lighting control equipment, especially relates to a rhythm sensor. BACKGROUND

[0002] Rhythm lighting is a research hotspot in the current lighting field, which controls the illuminance and color temperature of light to make the light meet the human rhythm, suppresses the secretion of melatonin in the daytime to make people keep excited and awake, thereby helping to improve the work and study effect and efficiency, and on the contrary, promotes the secretion of melatonin at night to make people sleep more easily and improve the sleep quality.

[0003] The rhythm sensor is one of the indispensable sensors in the rhythm lighting system, which senses the color temperature and illuminance of the current environment to determine whether the lighting data of the current environment meets the requirements of rhythm lighting, and the existing rhythm sensor usually transmits signals with the control system in a wireless manner, so that a battery is used to supply power for the rhythm sensor. Since the sensor needs to work continuously, the replacement frequency of the battery is relatively high, and the battery needs to be replaced once every 3-5 days, which leads to relatively poor user experience.

[0004] How to prolong the single working time of the rhythm sensor and reduce the replacement frequency of the battery is a technical problem to be solved in the current rhythm lighting field. CONTENT OF THE UTILITY MODEL

[0031] According to one embodiment of the utility model, as Figure 1 Indicated, a rhythm sensor, comprising:

[0032] Power supply 2, the power supply 2 is used to power supply sensor;

[0033] Central processing unit 1, the central processing unit 1 is connected with power supply 2, and the central processing unit 1 is further connected with radar module 3, ambient light sensing module 4 and wireless module 5;The radar module 3 carries out radar information scanning to environment, and sends scanning result to central processing unit 1, and the central processing unit 1 controls the opening and closing of ambient light sensing module 4 circuit according to the scanning result;Ambient light sensing module 4 carries out ambient light detection to environment, and sends detection result to central processing unit 1, and the central processing unit 1 sends the detection result through wireless module 5.In the embodiment, the wireless module 5 is Bluetooth module or radio frequency module, and preferably is Bluetooth module;The ambient light sensing module 4 detects the color temperature value and / or illumination value of environment.

[0034] Since the power supply 2 of the rhythm sensor is usually a battery, the radar module 3 and the ambient light sensing module 4 are both power-consuming components, and in the prior art, both power-consuming components are in a working state all the time, so the battery power is usually consumed in 3-5 days, and the user needs to replace the battery frequently to keep the rhythm lighting system running normally. This seriously affects the user experience, and based on this, the inventors of the present application designed the rhythm sensor of the present embodiment.

[0035] In the rhythm sensor of the present embodiment, the radar module 3 scans radar information, and then the central processor 1 controls the ambient light sensing module 4 circuit to close, and the ambient light sensing module 4 is in a power-consuming state; in the case where the radar module 3 does not recognize radar information, the ambient light sensing module 4 is in a power-off state, and when the radar module 3 does not scan radar information during the next radar information scanning of the environment, the central processor 1 controls the ambient light sensing module 4 circuit to open. In the case where there is no one in the environment, the radar module 3 of the rhythm sensor of the present embodiment cannot scan radar information all the time, and the ambient light sensing module 4 is always in a power-off state, which can greatly save power. Tests show that the rhythm sensor of the present embodiment can extend the single working time from the original 3-5 days to 20-40 days.

[0036] Further, to further extend the single working time of the rhythm sensor, in the present embodiment, the central processor 1 is built-in with a timer, which sends a first time signal to the central processor 1 at an interval of a time period, and the central processor 1 controls the circuit of the radar module 3 to be turned on according to the first time signal, performs radar information scanning, and controls the circuit of the radar module to be turned off after receiving the scanning result of the radar module 3. By setting the radar module 3 to an intermittent working mode, the power consumption of the radar module 3 is further reduced. In the present embodiment, the time period is 2-10 seconds.

[0037] In the present embodiment, the central processor 1 controls the circuit of the radar module 3 to be turned off after receiving the scanning result. That is, the radar line sensing module also adopts an intermittent working mode, which can further extend the single working time of the rhythm sensor to 3-5 months.

[0038] According to one embodiment of the utility model, the central processing unit 1 is further connected with a real time clock module 6, the central processing unit receives real time clock signal, controls radar module 3 circuit to be open in first time, controls radar module 3 circuit to be on in second time. For rhythm lighting system, in daytime, because of light, ambient light is usually in line with rhythm lighting requirement, so its working time is usually one hour before sunset to one hour after sunrise. Therefore, this embodiment is to further prolong the single working time of rhythm sensor, and the central processing unit 1 is connected with a real time clock module 6, the real time clock module 6 can record the current time, when the time comes to one hour after sunrise, the central processing unit 1 controls radar module 3 circuit to be disconnected, when the time comes to one hour before sunset, the central processing unit 1 controls radar module 3 circuit to be on, and then the central processing unit 1 controls radar module 3 to enter the mode of intermittent work.
