[0001] The invention belongs to the technical field of encoders and relates to an encoder, in particular to a mechanical rotary dual encoder and a data analysis method thereof. Background Art

[0002] An encoder is a device that compiles and converts signals or data into a signal form that can be used for communication, transmission or storage. An incremental encoder outputs the pulse signal emitted by each unit angle through phase A and phase B. Phase A and phase B are pulse outputs that are delayed by 1 / 4 of a cycle from each other. The forward and reverse rotations can be distinguished based on the delay relationship. Traditional non-contact encoders are relatively expensive. For products that do not require high rotation life and are relatively cost-sensitive, choosing a mechanical encoder is a better choice.

[0003] Therefore, how to provide a mechanical rotary dual encoder and its data analysis method to solve the defects of the existing mechanical encoders, such as being unable to adjust two different parameters on the same encoder by rotating different encoder caps and only being able to output one set of pulse data, has become a technical problem that needs to be urgently solved by technicians in this field.

[0046] Embodiment 1

[0047] This embodiment provides a mechanical rotary dual encoder, comprising:

[0048] PCB board;

[0049] A first rotary encoder is integrated on the PCB; the interior of the first encoder is hollow;

[0050] The second rotary encoder is arranged concentrically with the first rotary encoder and is integrated on the PCB board by passing through the interior of the first rotary encoder.

[0051] The following will describe in detail the mechanical rotary dual encoder provided by this embodiment in conjunction with the diagram. Figure 1 , which is a schematic diagram of the three-dimensional structure of a mechanical rotary dual encoder. Figure 1 As shown, the mechanical rotary dual encoder 1 comprises a PCB board 10 , a first rotary encoder 11 , a second rotary encoder 12 and a processor (not shown). The first rotary encoder 11 and the second rotary encoder 12 are integrated on the PCB board 10 .

[0052] See also Figure 2A , 2B and 2C respectively show the top view structural schematic diagram, the front view structural schematic diagram and the side view structural schematic diagram of the first rotary encoder.

[0053] like Figure 2A As shown, the first rotary encoder 11 includes a first outer ring 111 and a first rotating shaft 112 disposed in the first outer ring 111 , and the height of the first outer ring 111 is lower than the height of the first rotating shaft 112 .

[0054] In this embodiment, since the second rotary encoder 12 needs to pass through the interior of the first rotary encoder 11 and be integrated on the PCB board 10 , the interior of the first rotary encoder 11 needs to be hollow.

[0055] Specifically, the first rotating shaft 112 is hollow inside.

[0056] In order to facilitate the rotation of the first rotary encoder 11 , in practical applications, a first rotating cap 113 is sleeved on the first rotating shaft 112 .

[0057] Continue reading Figure 2B and 2C The first rotary encoder 11 further includes: first fixing feet 114 and 115 symmetrically arranged on the side wall of the first outer ring. The first fixing feet 114 and 115 are used to fix the first rotary encoder 11. Through the first fixing feet 114 and 115, when the first rotating cap 113 is twisted to drive the first rotating shaft 112 to rotate, the first rotary encoder 11 can be stably fixed on the PCB board 10.

[0058] The first A-phase signal output pin 116 and the first B-phase signal output pin 117 provided on the side wall of the first outer ring 112 are used to output the first characterization data. The first characterization data is used to represent the adjustment parameters of the first rotary encoder. In this embodiment, the adjustment parameters of the first rotary encoder include the rotation direction and adjustment amount of the first rotary encoder. In this embodiment, the first characterization data may be pulse data.

[0059] See also Figure 3A , 3B 3C respectively show the top view, front view and side view of the second rotary encoder.

[0060] like Figure 3A As shown, the second encoder 12 includes a second outer ring 121 and a second rotating shaft 122 disposed in the second outer ring 121. The second outer ring 122 is inserted into the hollow portion of the first rotating shaft 112.

[0061] In order to facilitate the rotation of the second rotary encoder 12, in actual application, a second rotary cap 123 is sleeved on the second rotating shaft 122. The first rotary cap 113 and the second rotary cap 123 have the same diameter. Since the diameters of the rotary caps of the two encoders are the same, the first rotary cap 113 and the second rotary cap 123 can be rotated simultaneously, and two different parameter values ​​can be adjusted at the same time.

[0062] Continue reading Figure 3B and 3C The second rotary encoder 12 further includes: second fixing feet 124 / 125 symmetrically arranged on the side wall of the second outer ring. The second fixing feet 124 / 125 are used to fix the second rotary encoder 12. Through the second fixing feet 124 and 125, when the second rotating cap 123 is twisted to drive the second rotating shaft 122 to rotate, the second rotary encoder 12 can be stably fixed on the PCB board 10.

[0063] The second A-phase signal output pin 126 and the second B-phase signal output pin 127 provided on the side wall of the second outer ring 121 are used to output the second characterization data. The second characterization data is used to represent the adjustment parameters of the second rotary encoder. The adjustment parameters of the second rotary encoder include the rotation direction and adjustment amount of the first rotary encoder. In this embodiment, the second characterization data may be pulse data.

[0064] The processor is disposed on the PCB board and connected to a dual encoder signal interface 13, and the dual encoder signal interface 13 is connected to the first A phase / first B phase signal output pin and the second A phase / second B phase signal output pin. The processor is used to receive the first characterization data and the second characterization data, and analyze the adjustment parameters of the first rotary encoder and / or the second rotary encoder according to the first characterization data and the second characterization data.

[0065] Specifically, when the first rotary encoder 11 is rotated, if the logic level output by the first A-phase signal output pin 116 is 0, and the logic level output by the first B-phase signal output pin 117 changes from 0 to 1, it indicates that a rising edge event occurs, and the processor determines that the first rotary encoder 11 is rotating clockwise, and then increases the adjustment amount by 1; if the logic level output by the first B-phase signal output pin 117 changes from 1 to 0, it indicates that a falling edge event occurs, and the processor determines that the first rotary encoder 11 is rotating counterclockwise, and then decreases the adjustment amount by 1. Conversely, if the logic level output by the first A-phase signal output pin 116 is 1, and the logic level output by the first B-phase signal output pin 117 changes from 0 to 1, it indicates that a rising edge event occurs, and the processor determines that the first rotary encoder 11 is rotating counterclockwise, and then decreases the adjustment amount by 1; if the logic level output by the first B-phase signal output pin 117 changes from 1 to 0, it indicates that a falling edge event occurs, and the processor determines that the first rotary encoder 11 is rotating clockwise, and then increases the adjustment amount by 1.

[0066] The mechanical rotary dual encoder described in this embodiment achieves the effect of having two encoder data groups output at one encoder position, and different data can be adjusted by rotating two different rotating caps at the same position.

[0067] Embodiment 2

[0068] This embodiment provides a data analysis method for a mechanical rotary dual encoder, wherein the mechanical rotary dual encoder includes a first rotary encoder and a second rotary encoder arranged concentrically with the first rotary encoder.

[0069] See also Figure 4 , which is a flow chart of a data analysis method for a mechanical rotary dual encoder in one embodiment. Figure 4 As shown, the data analysis method of the mechanical rotary dual encoder specifically includes the following steps:

[0070] S41, receiving first characterization data output by the first rotary encoder and second characterization data output by the second rotary encoder. The first characterization data is used to represent the adjustment parameters of the first rotary encoder; the second characterization data is used to represent the adjustment parameters of the second rotary encoder. In this embodiment, the first characterization data and the second characterization data may be pulse data. The adjustment parameters of the first rotary encoder include the rotation direction and adjustment amount of the first rotary encoder; the adjustment parameters of the second rotary encoder include the rotation direction and adjustment amount of the first rotary encoder.

[0071] S42: Analyze adjustment parameters of the first rotary encoder and / or the second rotary encoder according to the first characterization data and the second characterization data.

[0072] Specifically, when the first rotary encoder is rotated, if the logic level output by the first A-phase signal output pin is 0 and the logic level output by the first B-phase signal output pin changes from 0 to 1, it indicates that a rising edge event occurs, and the first rotary encoder is judged to be rotating clockwise, and the adjustment amount is increased by 1; if the logic level output by the first B-phase signal output pin changes from 1 to 0, it indicates that a falling edge event occurs, and the first rotary encoder is judged to be rotating counterclockwise, and the adjustment amount is reduced by 1. Conversely, if the logic level output by the first A-phase signal output pin is 1 and the logic level output by the first B-phase signal output pin changes from 0 to 1, it indicates that a rising edge event occurs, and the first rotary encoder is judged to be rotating counterclockwise, and the adjustment amount is reduced by 1; if the logic level output by the first B-phase signal output pin changes from 1 to 0, it indicates that a falling edge event occurs, and the first rotary encoder is judged to be rotating clockwise, and the adjustment amount is increased by 1.

[0073] In summary, the mechanical rotary dual encoder of the present invention achieves the effect of outputting two encoder data groups at one encoder position, and different data can be adjusted by rotating two different rotary caps at the same position. The present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
