AI Technical Summary
Existing smart sensor lights suffer from insufficient sensing sensitivity, mainly due to the Doppler sensor's configuration, which leads to blind spots and reduced sensitivity.
Doppler sensors are arranged in a spiral pattern from top to bottom along the inner wall of the detection box. Each sensor is equidistant from its adjacent sensors and the connecting lines are not parallel or perpendicular to the horizontal plane. Combined with sound, temperature and vibration sensors, a multi-sensing mechanism is formed to ensure no blind spots and high sensitivity.
It achieves seamless sensing, improves the sensitivity of the sensor light, and can still operate efficiently even when the sensor fails, ensuring that lighting needs are met.

[0027] An intelligent induction lamp mainly comprises a detection module, a controller module, a lamp strip and a detection box 2. The detection module comprises at least M (M≥3) Doppler sensors 1. For each Doppler sensor 1, the output end of the Doppler sensor 1 is connected with the controller module. The control signal output by the controller module controls the on-off of the lamp strip. Each Doppler sensor 1 is installed in the detection box 2 and is distributed in a spiral shape from top to bottom along the inner wall of the detection box 2. For each Doppler sensor 1 on the spiral line, the two horizontal distances formed by the Doppler sensor 1 and the two adjacent Doppler sensors 1 are equal. For each Doppler sensor 1 on the spiral line, the two vertical distances formed by the Doppler sensor 1 and the two adjacent Doppler sensors 1 are equal. The connecting line of any two Doppler sensors 1 is not parallel or perpendicular to the horizontal plane. The setting mode of the Doppler sensor 1 of the utility model is shown in Figure 1 The principle block diagram of the utility model is shown in Figure 2 .
[0028] The Doppler sensor 1 comprises an oscillator, a transmitting antenna, a receiving antenna, a mixer, a filter, an amplifier, an analog-to-digital converter, a Fourier transformer and a determinator, wherein the oscillator generates an oscillation signal which is transmitted in the sensing area through the transmitting antenna, the receiving antenna receives signals in the sensing area, the transmitting signals and the receiving signals enter the mixer for frequency mixing, the Doppler signals are obtained through the filter, the Doppler signals are amplified through the amplifier, are analog-to-digital converted through the analog-to-digital converter, are Fourier transformed through the Fourier transformer, and then the determinator can determine whether a person enters the sensing area.
[0029] The Doppler sensors 1 are arranged in a spiral shape, for each Doppler sensor 1 on the spiral line, the two horizontal distances formed by the Doppler sensor 1 and the two adjacent Doppler sensors 1 are equal, and the two vertical distances formed are equal, so that the Doppler sensors 1 can be uniformly distributed in the required sensing area, and the no-dead-angle sensing is realized as much as possible, and further, the connecting lines of any two Doppler sensors 1 are not parallel or perpendicular to the horizontal plane, so that the situation that the sensing areas of the Doppler sensors 1 completely overlap can be avoided, the number of Doppler sensors is reduced, the cost is reduced, excessive redundant detection and data processing are avoided, the sensing speed is accelerated, and the sensing sensitivity is ensured. The working of each Doppler sensor 1 is independent and complementary, and when one Doppler sensor 1 cannot work normally, the normal work of other Doppler sensors 1 will not be affected, and the sensing area and the sensing sensitivity are not or rarely affected.
[0030] Further, the detection module further comprises a sound sensor; the sound sensor is installed in the detection box 2; and an output end of the sound sensor is connected with the controller module. When all the Doppler sensors 1 cannot work normally, the output signal of the sound sensor can replace the Doppler sensors 1 to control the light band to be bright or dark.
[0031] Further, a heat-conducting shell 4 is further included; the light band is installed in the inner cavity of the heat-conducting shell 4; the light band is installed in the heat-conducting shell 4, and the heat-conducting shell 4 is independent of the detection box 2, that is, the light band is independent of the Doppler sensors 1 and the sound sensor, and the installation position can be in different places, which is more convenient for adjusting the sensing area and the illumination range, and has a great improvement on the sensitivity.

In the case that the lamp strip is installed at a relatively low position, when the Doppler sensor 1 and the sound sensor in the detection box 2 cannot work normally, the user can also put his hand on the heat-conducting shell 4, and the temperature of the hand is transmitted to the temperature sensor 3 through the heat-conducting shell 4, and the temperature sensor 3 outputs a signal to the controller module, thereby controlling the on-off of the lamp strip. The temperature sensor 3 is arranged in a spiral shape, and for each temperature sensor 3 on the spiral line, the two horizontal distances formed by the temperature sensor 3 and the two adjacent temperature sensors 3 are equal, and the two vertical distances formed are equal, and each temperature sensor 3 is uniformly arranged on the inner wall of the heat-conducting shell 4, no matter which part of the heat-conducting shell 4 is touched by the user, at least one temperature sensor 3 corresponding to the position can be touched, and the uniform arrangement of the temperature sensor 3 can avoid missed detection.

The computer program involved in the utility model is simple detection and control, and does not involve improvement of computer programs. In the utility model, it has been clearly indicated in the specification that the technical solution is to provide hardware structure support for solving the problem of low sensing sensitivity in the prior art, that is, only the hardware structure contributes to the purpose. From the analysis of beneficial effects, it can be known that the technical solution is to improve the setting mode of the Doppler sensor 1 to achieve the purpose, that is, the technical solution provides hardware structure support for solving the corresponding technical problem from the optimization of the setting mode, at the same time, the corresponding hardware structure is also applied for protection in the claim.
