Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
In a preferred embodiment, referring to fig. 1, fig. 3 and fig. 4, the testing apparatus for a photoelectric direct-reading circuit board of a water meter in this embodiment includes a frame body 101, a character wheel rotating shaft 102, at least two character wheels 103, at least two stepping motors 104 and a testing controller 105, where the frame body 101 is an integral frame of the testing apparatus and is used for installing various testing modules, a testing card position for installing the photoelectric direct-reading circuit board 20 is arranged on the frame body 101, and the photoelectric direct-reading circuit board 20 is detachably installed at the testing card position. The character wheel rotating shaft 102 is fixed on the frame body 101, and alternatively, the character wheel rotating shaft 102 is horizontally fixed on the frame body 101. All character wheels 103 are rotatably arranged on the character wheel rotating shaft 102 at intervals, and the end surfaces of the character wheels 103 are provided with preset code hollowed-out patterns 1031. Each print wheel 103 corresponds to a stepping motor 104, and the stepping motor 104 is used for driving the corresponding print wheel 103 to rotate. The test controller 105 is connected to and drives the stepper motors 104 to rotate, and the test controller 105 drives only one stepper motor 104 to rotate at a time. The test controller 105 includes a test interface for connecting the optoelectronic direct reading circuit board 20, and the optoelectronic direct reading circuit board 20 is mounted on the test card and then connects the optoelectronic direct reading circuit board 20 to the test interface.
The photoelectric direct-reading circuit board 20 enters a working state after being powered on, each group of the light emitting module 202 and the light receiving module 203 corresponds to one character wheel 103, light emitted by the light emitting module 202 is transmitted to the light receiving module 203 through the preset code hollow-out pattern 1031 of the character wheel 103, and the light receiving module 203 acquires collected data. The test controller 105 acquires the collected data of the photoelectric direct reading circuit board 20, and determines whether the photoelectric direct reading circuit board 20 is normal according to the collected data.
Alternatively, the test controller 105 stores the corresponding relationship between the step number of the stepping motor 104 and the number wheel reading, and the test controller 105 controls the step number of the part motor 104 to search the number wheel reading corresponding to the current step number according to the corresponding relationship between the step number and the number wheel reading. Meanwhile, the test controller 105 decodes the acquired data according to a preset decoding algorithm to obtain a character wheel reading, and further determines whether the character wheel reading corresponding to the current stepping number of the stepping motor 104 is consistent with the character wheel reading obtained by decoding. If the character wheel reading corresponding to the previous stepping number is consistent with the character wheel reading obtained by decoding, the photoelectric direct-reading circuit board 20 is normal; if the character wheel reading corresponding to the previous step number is not consistent with the character wheel reading obtained by decoding, it indicates that the photoelectric direct-reading circuit board 20 is abnormal.
Optionally, because the end surface of the print wheel 103 has the preset code hollow pattern 1031, the light emitting module 202 emits light when the intelligent water meter reads, light passes through the preset code hollow pattern 1031 of the print wheel 103 and then emits to the light receiving module 203, the receiving light of the decoding light receiving module 203 is different when the print wheel 103 is at different positions, the test controller 105 decodes the collected data according to the preset decoding algorithm to obtain a print wheel reading, wherein the prior art can be referred to when the test controller 105 decodes the collected data according to the preset decoding algorithm to obtain the print wheel reading, and the description is omitted here. Further, it is determined whether the word wheel reading is consistent with a preset reading, such as 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. If the number wheel reading is consistent with the preset reading, the photoelectric direct-reading circuit board 20 is normal; if the number wheel reading is not consistent with the preset reading, it indicates that the photoelectric direct-reading circuit board 20 is abnormal.
In this embodiment, after each stepping motor 104 drives one print wheel 103, the test time can be greatly saved, and the test time comparison is performed with the prior art by taking the intelligent water meter with the range of 0 to 9999 as an example:
the prior art only sets up step motor 104 in unit character wheel department, then tests four step motor 104 and needs unit character wheel and rotate 9999 circles, and unit character wheel, ten position character wheel, hundred position character wheel and thousand position character wheel in this application each all correspond a step motor 104, then every character wheel only need rotate 1 circle, rotate 4 circles altogether promptly. Therefore, the time saving of the embodiment is (9999-4)/9999 ≈ 0.9996, that is, the embodiment can save the test time by 99.96%, and has a significant beneficial effect.
The same calculation can be carried out, the test time of the intelligent water meter with the measuring range of 0-999 can be saved by (999-4)/999 ≈ 0.9996, namely the test time can be saved by 99.96% by the embodiment, and the method has a remarkable beneficial effect.
In conclusion, the linkage driving mode between the character wheels is eliminated, and an independent stepping motor is arranged for each character wheel, so that the testing time is greatly saved, and the testing efficiency is greatly improved. It can be understood that the larger the range of the intelligent water meter is, the more the test time is saved by the embodiment.
