Embodiment Construction
[0051] The embodiment of the present invention will be explained in detail below in conjunction with the accompanying drawings. The examples given are only for the purpose of illustration, and cannot be interpreted as limiting the present invention. The accompanying drawings are only for reference and description, and do not constitute the scope of patent protection of the present invention. limitations, since many changes may be made in the invention without departing from the spirit and scope of the invention.
[0052] refer to figure 1 , an embodiment of the present invention provides an adaptive ultrasonic object detection method, such as figure 1 As shown, the method is based on an ultrasonic detection device for ultrasonic objects. The ultrasonic detection device includes a temperature sensor and several ultrasonic transmitters and ultrasonic receivers arranged on one side. The method includes the following steps:
[0053] S1. Set the effective detection distance of eac...

The invention relates to the technical field of ultrasonic detection, in particular to a self-adaptive ultrasonic object detection method, system and device and a storage medium, and the method comprises the steps: determining an effective detection distance, and in any number of detection rounds, sequentially selecting an ultrasonic transmitter to transmit ultrasonic waves, simultaneously driving all the ultrasonic receivers to receive the ultrasonic waves reflected within the effective detection distance and recording the echo time of the ultrasonic waves until traversing to the last ultrasonic transmitter to obtain an echo time matrix; the to-be-detected object is detected according to the echo time matrix and the sound velocity, so that the problems that an existing infrared diffuse reflection type object detection device is difficult to use in an outdoor environment, has specific requirements on the color and the background of the to-be-detected object and cannot be used in an occasion with thick smoke are solved; according to the invention, the to-be-detected object is automatically detected through different echo times, the workload of workers is reduced, the detection efficiency and precision are improved, and the false identification rate of the object is effectively reduced.
Description
technical field [0001] The invention relates to the technical field of ultrasonic detection, in particular to an adaptive ultrasonic object detection method, system, equipment and storage medium. Background technique [0002] The infrared diffuse reflection object detection device is equipped with an infrared emitting tube and an infrared receiving tube inside, which can not only emit infrared rays to the outside, but also receive infrared rays reflected from external objects, and its application is very wide. [0003] However, due to its flaws, it cannot be applied to a variety of scenarios, including: [0004] (1) It is difficult to use in an outdoor environment; due to the outdoor sunlight at noon, it is easier to reach 2*10 5 Lux, the illuminance of the infrared light part is 1 to 3 orders of magnitude higher than that of the infrared light source of the common infrared diffuse reflection detection device, which makes the detection device unable to distinguish the refle...
