[0023] The present invention will be further described below with reference to the drawings and embodiments.

[0024] Size coding is a commonly used coding method, which codes different sizes. Due to individual differences, different people have different recognition abilities for size coding. In order to measure the specific value of the recognition ability of the test individual for size coding, the present invention designs a set of ergonomic measuring instruments for the recognition of size coding.

[0025] Embodiment 1

[0026] This embodiment provides an ergonomic measuring instrument for the recognition of size coding, including at least two simulation measuring blocks 1 of different sizes, and the simulation measuring blocks 1 are rotatably mounted on a base 3. Specifically, the simulation measuring block includes a measuring part 11 and a mounting part 12. As Figure 2 shown, the mounting part 12 is rotatably mounted on the base 3, and the base 3 is provided with a mounting hole for mounting the mounting part 12; for the convenience of operation, as Figure 1 shown, both the measuring part 11 and the mounting part 12 are cylindrical.

[0027] Since the operation of the manipulator is basically a blind operation process, the present application simulates the measurement of recognition in a blind state. The measuring instrument further includes a shutter 2 for blocking the line of sight of the tested person, and the shutter 2 is provided with an opening for operation. Preferably, the shutter 2 is an L-shaped plate with a base 3. During operation, the operator's hand can extend from its top or side for recognition.

[0028] Embodiment 2

[0029] This embodiment provides a recognition method for using the measuring instrument of Embodiment 1 to measure recognition, specifically including:

[0030] Step 1: Determine the recognition size A to be measured. The present application takes the recognition size A as 30 mm as an example for illustration. Here, 30 mm means that the outer diameter of the simulation measuring block 1 is 30 mm. Then, at least two simulation measuring blocks 1 matching the recognition size A are selected, and all the simulation measuring blocks 1 are rotatably mounted on the base 3. The shutter is placed on one side of all the bases 3 to block the line of sight, as Figure 3 shown;

[0031] Step 2: Record the start operation time. By operating two simulated measurement blocks 1 in sequence, where the operation here refers to touching and rotating the measurement module by hand to identify its size, and identify the similarities and differences in size A and size B of the two; the identification results include the same size, different sizes, or indistinguishable; when the identification result is different sizes or indistinguishable, then replace the simulated measurement block 1 with size B with a simulated measurement block 1 of other sizes, and repeat the above steps to continue the identification of size similarities and differences until a measurement simulation block that can be distinguished from the distinguishable size A is identified, and record the size of this measurement simulation block, which is the distinguishable ability above the order of magnitude of the distinguishable size A; size A and B refer to the outer diameter of the measurement part 11 of the corresponding measurement simulation block; in this step, the simulated measurement block 1 is operated in a sitting position state.

[0032] Step 3: After the identification is completed, record the time required for completion and the identification result, then this size B is the distinguishable ability above the order of magnitude of 30 mm.

[0033] Embodiment III

[0034] Since the installation positions of the two simulated measurement blocks are relatively close, during actual operation, due to the need for blind operation, the tester's line of sight is blocked, and there may be a problem that the tester is not sure which simulated measurement block is touched. This embodiment provides an improved ergonomic measuring instrument for size coding distinguishability, including at least two simulated measurement blocks 1 of different sizes, and the simulated measurement blocks 1 are rotatably installed on the base 3. As Figure 1 shown, the simulated measurement block includes a measurement part 11 and an installation part 12, the installation part 12 is rotatably installed on the base 3, and the base 3 is provided with an installation hole for installing the installation part 12; for easy operation, both the measurement part 11 and the installation part 12 are cylindrical.

[0035] Since the operation process is basically blind operation, therefore, this application simulates the measurement of distinguishability in a blind state, and the measuring instrument further includes a shield 2 for blocking the line of sight of the tested person, and the shield 2 is provided with an opening for operation. Preferably, the shield 2 is an L-shaped plate with a base 3, and during operation, the operator's hand can reach in from its top or side for identification.

[0036] As Figure 4As shown, a plurality of magnets 13 arranged in a circle are mounted on the circumferential sides of the two analog measurement blocks 1 (only the mounting layout on one side is shown in the figure). The shutter 2 has a divided left area and right area. Hall switches 14 for detecting whether the two analog measurement blocks 1 rotate are respectively mounted on the inner sides of the left area and the right area of the shutter 2. Indicator lights 15 connected to the output ends of the Hall switches 14 are respectively provided on the outer sides of the left area and the right area. In this embodiment, the indicator lights are specifically LED indicator lights. The shutter 2 is also embedded with a power module for supplying power to the Hall switches and the indicator lights. The selection of the Hall switches, the power supply connection, the interface circuit, etc. all belong to conventional technologies and are not particularly limited in this embodiment, nor will they be elaborated here.

[0037] In some feasible embodiments, a power module can also be provided in the base 3 and connected to the Hall switch 14 and the indicator light 15 through wires respectively.

[0038] In this embodiment, each of the plurality of magnets is a strip-shaped permanent magnet; the Hall switch adopts a unipolar Hall switch.

[0039] When the analog measurement block 1 in the left area is rotated, the Hall switch on the inner side of the left area of the shutter 2 detects the pulse signals of the magnets 13 on the left analog measurement block 1 approaching and moving away in sequence, driving the indicator light in the left area of the shutter 2 to flash, prompting the user that the currently touched and rotated is the left analog measurement block.

[0040] Similarly, when the analog measurement block 1 in the right area is rotated, the Hall switch on the inner side of the right area of the shutter 2 detects the pulse signals of the magnets 13 on the left analog measurement block 1 approaching and moving away in sequence, driving the indicator light in the right area of the shutter 2 to flash, prompting the user that the currently touched and rotated is the right analog measurement block.

[0041] Therefore, by adopting the improved scheme provided in this embodiment, when the left or right analog measurement block 1 is rotated by the user, the plurality of magnets built in it approach the Hall switch in turn, generating pulse signals, and driving the LED indicator light to flash through the pulse signals, so that the user can determine that the currently operated and touched is the left or right analog measurement block, thus solving the problem that the tester is not sure which analog measurement block is touched.

[0042] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification. Moreover, the above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
