The knob is used in most electrical equipment, and when the electrical equipment is actually used, a user is required to rotate the knob to set. For the blind, the current state of the knob cannot be sensed directly by touching, especially for some 'no paragraph' knobs (such as temperature adjusting knob and time adjusting knob). Accordingly, the inventors have found that the above-mentioned problems are achieved by installing the positioning magnet 1 on the knob 4 and installing the detection block 2 including the magnetic force sensor on one side of the knob 4 according to the principles of the positioning magnet 1 and the magnetic force sensor, and finally realizing voice playback through the host computer 3. Therefore, the blind person can know the current accurate state of the knob 4 according to the voice broadcasting condition, the blind person can conveniently operate various electrical equipment 8, and the living standard of the blind person is improved.

The application relates to a device for detecting the state of electrical equipment 8 for the blind, which is mainly used for electrical equipment 8 of life, for example: oven, juicer, air fryer, electric fan, electric rice cooker, etc.

Referring to fig. 1 to 4, according to some embodiments of the present application, the present embodiment relates to an apparatus for detecting a state of an electrical device 8 for a blind person, which includes a positioning magnet 1, a detection block 2, and a host 3, wherein the positioning magnet 1 is mounted on a knob 4 of the electrical device 8; the detection block 2 is arranged on one side of the knob 4 of the electrical equipment 8, the detection block 2 comprises a magnetic force sensor, and the detection block 2 is used for detecting state information of the knob 4 of the electrical equipment 8 through the magnetic force sensor; the host computer 3 is installed on the electrical equipment 8, and the host computer 3 is connected with the detection block 2 in a communication way, and the host computer 3 comprises a host computer processing module 32 and a voice module 33, and the host computer processing module 32 is used for receiving the state information of the knob 4 of the electrical equipment 8 sent by the detection block 2 and controlling the voice output of the voice module 33.

As shown in fig. 1, a schematic structure of a device for detecting the state of an electrical apparatus 8 for the blind is installed on the electrical apparatus 8, i.e. an oven. The application only needs to install the positioning magnet 1 on the existing knob 4, and the disassembly and transformation of the knob 4 are not needed. Thus, the present application is applicable to knobs 4 of various sizes.

The detection block 2 is installed at one side of the knob 4 of the electric device 8, and as shown in fig. 2, the detection block 2 is uniformly installed at the upper right of the knob 4. In some embodiments, the mounting position of the detection block 2 may be adjusted according to the size of the control panel and the position of the knob 4 on the control panel. For example: the detection blocks 2 may also be uniformly installed right above or left or right side of the knob 4, etc. Wherein, in order to ensure that the magnetic force sensor arranged in the detection block 2 can better sense the magnetic field information of the positioning magnet 1 (the farther the magnetic force sensor is from the positioning magnet 1, the smaller the detected magnetic force is, the more easily the signal is disturbed), the detection block 2 is arranged close to the knob 4. Since the detection block 2 and the host 3 are designed separately and the volume of the detection block 2 is not large, the detection block 2 can be applied to the electrical equipment 8 with a smaller control panel area.

Each detection block 2 may use a plurality of unidirectional sensors, or may use a multidirectional sensor. Alternatively, three-axis magnetic force sensors are typically used, which are low cost, low requirements for production assembly, and many suppliers. As shown in fig. 4, the working principle is as follows: first, the positioning magnet 1 is mounted on the knob 4 such that the magnetizing direction C of the positioning magnet 1 is not parallel to the rotation axis direction N of the knob 4. Preferably, the magnetizing direction C of the positioning magnet 1 is perpendicular to the rotation axis direction N of the knob 4. Second, the detection block 2 is mounted close to the knob 4. Preferably, the magnetizing direction C of the positioning magnet 1 is made parallel to the sensor XY plane. Third, the center of the sensor in fig. 4 is denoted by O, and at this time, the magnetic vector F (x 1, y1, z 1) can be read from the three-axis magnetic force sensor, and the value of the angle a can be calculated by the formula "a=arctan (|y1|/|x1|)". By combining the signs of X1 and y1, the counterclockwise rotation angle value of the projection of the magnetic vector F (X1, y1, z 1) on the XY plane with respect to the positive direction of the X axis can be obtained, and this angle value changes with the rotation of the knob 4, and thus can be used to represent the direction information of the knob 4.

The host 3 is mainly connected to the detection block 2, and may be a wired connection or a wireless connection. The host computer 3 analyzes and processes the state information of the knob 4 of the electrical equipment 8 detected by the detection block 2 to obtain the state of the electrical equipment 8 in real time, and outputs the state through the voice module 33.

According to the technical scheme, the positioning magnet 1 is arranged on the knob 4 of the electrical equipment 8, the positioning magnet 1 rotates along with the knob 4, the magnetic sensor in the detection block 2 detects the state information of the knob 4 of the electrical equipment 8 through the rotation of the positioning magnet 1, the angle data of the knob 4 is obtained through analysis of the processing module of the host computer 3, the state of the electrical equipment 8 in real time is obtained, and finally the current accurate state of the knob 4 can be known by the blind person through voice output of the voice module 33, so that the blind person can operate various electrical equipment 8 conveniently, and the living standard of the blind person is improved.
