[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0026] Example 1

[0027] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides an opening display system based on a pull-wire rotary encoder, including a stop unit 100 and a measuring unit 200.

[0028] Preferably, the gate blocking unit 100 includes a gate 101, a support arm 102, a traction line 103, an arc plate 104, and a hinge 105. One end of the support arm 102 is located on one side of the gate 101. The traction line 103 is located on the support arm 102 and is connected to a power source. The gate 101 is opened and closed through the traction line 103. The arc plate 104 is located on the support arm 102 and is used to set the connector of the pull-wire encoder. When the gate 101 rotates, the pull-wire encoder stretches or contracts. The other end of the support arm 102 is provided with a hinge 105. The hinge 105 is located on both sides of the gate. The gate 101 rotates around the hinge 105 as the axis. The arc plate 104 has the same axis as the hinge 105.

[0029] Preferably, the measuring unit 200 includes a wire encoder 201, a measuring device 202, and a power supply 203. The wire encoder 201 is installed inside the gate. When the gate 101 rotates, the length of the wire of the wire encoder 201 corresponds to the opening degree of the gate 101. The measuring device 202 is installed on one side of the wire encoder 201, and the power supply 203 is installed on one side of the wire encoder 201. The measuring device 202 calculates the opening degree of the gate 101 by measuring the length of the wire of the wire encoder 201.

[0030] In use, the traction line 103 is connected to the power source. The gate 101 is opened by rotating the traction line 103 around the hinge 105. The arc plate 104 is set on the support arm 102. The arc plate 104 is used to set the connector on the pull-wire encoder. When the gate 101 is opened, the arc plate 104 rotates with the support arm 102 to pull the pull wire in the pull-wire encoder 201 outward. The pull-wire encoder 201 is set in the gate passage. The measuring device 202 calculates the opening degree of the gate 101 by measuring the length of the pull wire of the pull-wire encoder 201. This avoids setting the pull-wire encoder 201 on the gate actuator, because the gate actuator has a huge rotational torque during operation. Vibration, slippage, jamming or over-adjustment will damage the rotary encoder.

[0031] Example 2

[0032] Reference Figures 1-4 This is the second embodiment of the present invention. Unlike the previous embodiment, it also includes a gate 101 that is opened and closed by a traction line 103 set on the support arm 102, with one end of the traction line 103 connected to a power source.

[0033] Preferably, the hinge 105 is disposed on the side wall of the gate, and the gate 101 is opened and closed by rotating around the hinge 105.

[0034] Preferably, the pull-wire encoder 201 includes a housing 201a, a pull wire 201b, and a connector 201c, with the pull wire 201b connecting the connector 201c and the housing 201a.

[0035] Furthermore, the housing 201a is fixedly installed inside the gate, that is, the housing 201a is fixedly installed during measurement.

[0036] Furthermore, the connector 201c is disposed on the arc plate 104. The connector 201c is retractable via the pull wire 201b. The pull wire 201b of the suspended edge of the pull-wire encoder 201 is connected to the arc plate 104 via the connector 201c.

[0037] Furthermore, when the arc plate 104 on the support arm 102 moves at a constant angular velocity, the tension cable 201b stretches or contracts accordingly. The arc plate 104 and the hinge 105 have the same axis, and the arc plate 104 has a shock absorption effect. Constant angular velocity motion is also called uniform circular motion (UCM), which means that when an object moves along a circular path, the magnitude of its velocity remains constant, but its direction changes continuously.

[0038] In use, the gate 101 is opened and closed by the traction line 103 set on the support arm 102. One end of the traction line 103 is connected to the power source. The gate 101 opens and closes by rotating at a constant angular velocity with the hinge 105 as the axis. The pull line 201b of the suspended side of the pull-wire encoder 201 is connected to the arc plate 104 through the connector 201c.

[0039] Example 3

[0040] Reference Figure 5 This is the third embodiment of the present invention. Unlike the previous embodiment, the measuring device 202 includes a processor 202a, an input component 202b, an output component 202c, a first relay 202d, and a second relay 202e. The input component 202b, the output component 202c, the first relay 202d, and the second relay 202e are electrically connected to the processor 202a. The specific measurement method of the measuring device 202 is as follows:

[0041] Output component 202c displays the opening degree = (current input component code value - input code value when the gate is fully closed) × (maximum gate lifting height / input code value at maximum gate lifting height - input code value when the gate is fully closed)

[0042] Preferably, the processor 202a is an LGT328P chip.

[0043] Preferably, the wire encoder 201 is model ZQK-D-5V10K-1M.

[0044] In use, the pull wire 201b of the pull-wire encoder 201 is mainly used to measure the rotational displacement of the hinge 105, and then display the opening degree of the gate 101. First, the input code value when the gate is fully closed, the maximum lifting height of the gate, the input code value when the gate is at its maximum lifting height, and the input code value when the gate is fully closed are input through the input device 202b. According to the above calculation formula, the distance pulled out by the pull wire 201b is fed back as the current input code value. After the processor 202a calculates, the result is fed back from the output device 202c, so the opening degree of the gate 101 can be obtained in real time.
