Description

Technical Field

[0001] This utility model relates to the technical field of identification equipment, and in particular to a kiln car number identification structure. Background Technology

[0002] In the traditional use of tunnel kiln cars, the lack of numbering makes it difficult to accurately track product loading and material flow paths. However, with the increasing demands for refined management of kiln processes and product quality control, numbering kiln cars to clearly identify the specific loading location and status of products upon entering the kiln has become a common requirement in the industry. Kiln cars operate in harsh environments with high temperatures and high dust levels for extended periods. If QR codes or image recognition devices are used, they are prone to problems such as QR code detachment and image blurring due to high-temperature corrosion and dust accumulation, thus affecting number recognition. While existing technologies apply binary recognition principles to kiln car number identification, the binary recognition code detection device consists of detection holes and detection elements. The detection holes are set on the sand seal plate of the kiln car, and different hole arrays are used to distinguish the kiln car number. If the kiln car number range is 1 to 100, 100 sand seal plates with different hole arrays are needed. This is not only complex in manufacturing but also inconvenient, requiring replacement of the sand seal plates when the kiln car number needs to be changed. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a kiln car number identification structure. It can not only solve the technical problem that "when using QR codes or images as encoding identification devices, after long-term high-temperature corrosion and dust coverage, QR codes are easily missing or images are blurred", but also modify the kiln car number without replacing the sand seal plate. Moreover, the modification is relatively simple and does not require preparing too many sand seal plates with different hole arrays.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A kiln car number identification structure includes a mounting base, a wake-up component, several sensors, a detection device, and a PLC control system.

[0006] The mounting base is located at the front end of the kiln car, and the mounting base is equipped with an auxiliary sensing structure;

[0007] The wake-up device is mounted on the mounting base;

[0008] Several sensors are detachably mounted on the mounting base and cooperate with the auxiliary sensing structure to form a binary sensing array corresponding to the kiln car number;

[0009] The detection device is installed on the kiln base surface at the kiln loading location;

[0010] The PLC control system is electrically connected to the detection device.

[0011] In this technical solution, when the kiln car approaches the kiln loading position along the track, the PLC control system is activated by a wake-up device. Then, the PLC control system receives the signal from the detection device and performs binary code recognition to obtain the kiln car number. This technical solution uses a binary recognition device (several sensors + auxiliary sensing structure of the mounting base + detection device) to identify the kiln car number based on the binary recognition principle. This solves the technical problem that "when using QR codes or images for encoding and recognition, after long-term high-temperature corrosion and dust coverage, QR codes are easily missing, images are blurred, etc., causing unstable number recognition."

[0012] In addition, this technical solution only requires the fabrication of multiple sensors with a uniform structure, which, together with the mounting base, can form a binary sensor array corresponding to the binary code of the kiln car number. Compared with the existing technology that requires the fabrication of N sand seal plates with different hole arrays, this technical solution is easier to fabricate and the kiln car number can be modified without replacing the sand seal plate, and the modification is relatively simple.

[0013] Furthermore, the auxiliary sensing structure includes multiple blocking portions and multiple spaced holes;

[0014] Multiple blocking sections and multiple spacing holes are arranged at intervals along the length of the kiln car body;

[0015] The sensing element is paired with the corresponding blocking part according to the requirements.

[0016] Furthermore, the sensing element is provided with a clamping part, and the sensing element is detachably mounted on the mounting base through the clamping part.

[0017] Furthermore, the clamping part clamps the mounting base after passing through the spacer holes on both sides of the blocking part corresponding to its sensing element.

[0018] Furthermore, the mounting base is provided with a limiting structure for limiting the position of the sensing element.

[0019] Furthermore, the limiting structure is a limiting hole;

[0020] The sensing element is disposed in the corresponding limiting hole.

[0021] Furthermore, the wake-up element is elongated, extending from one end of the binary sensing array to the other end, with the end of the wake-up element near the detection device protruding from the mounting base.

[0022] Furthermore, the detection device includes a sensing element and a mounting bracket;

[0023] The sensing element is mounted on the kiln base surface at the kiln loading position via a mounting bracket and is electrically connected to the PLC control system.

[0024] Furthermore, the sensing element includes three proximity switches, which correspond to the wake-up element, auxiliary sensing structure, and sensing element on the mounting base, respectively.

[0025] Furthermore, the mounting bracket is provided with multiple waist holes;

[0026] The proximity switch is mounted in the corresponding waist hole via a nut assembly.

[0027] Compared with existing technologies, the principles and advantages of this technical solution are as follows:

[0028] In this technical solution, when the kiln car approaches the kiln loading position along the track, the PLC control system is activated by a wake-up device. Then, the PLC control system receives the signal from the detection device and performs binary code recognition to obtain the kiln car number. This technical solution uses a binary recognition device (several sensors + auxiliary sensing structure of the mounting base + detection device) to identify the kiln car number based on the binary recognition principle. This solves the technical problem that "when using QR codes or images for encoding and recognition, after long-term high-temperature corrosion and dust coverage, QR codes are easily missing, images are blurred, etc., causing unstable number recognition."

[0029] Furthermore, this technical solution only requires the fabrication of multiple sensors with a uniform structure. Combined with mounting bases, this forms a binary sensor array corresponding to the required kiln car number, which is significantly more convenient than the existing technology that requires the fabrication of numerous sand sealing plates with different hole arrays. When the kiln car number needs to be modified, only the distribution of the sensors needs to be adjusted to obtain the corresponding number; there is no need to replace the sand sealing plates.

[0039] The present invention will be further described below with reference to specific embodiments:

[0040] like Figures 1 to 6 As shown, the kiln car number identification structure described in this embodiment includes a mounting base 1, a wake-up component 3, several sensors 4, a detection device 5, and a PLC control system.

[0041] The mounting base 1 is located at the front end of the kiln car 1 (the top of the mounting base 1 is connected to the bottom of the kiln car 1), and an auxiliary sensing structure is provided in the middle of the mounting base 1; the wake-up element 3 is installed on the mounting base 1 and located above the auxiliary sensing structure; several sensing elements 4 are detachably installed on the mounting base 1 and located below the auxiliary sensing structure, and cooperate with the auxiliary sensing structure to form a binary sensing array corresponding to the kiln car number; the detection device 5 is installed on the kiln base surface at the kiln loading position; the PLC control system is electrically connected to the detection device 5.

[0042] Specifically, in this embodiment, the auxiliary sensing structure includes eight blocking parts 6 and eight spacer holes 7; the eight blocking parts 6 and eight spacer holes 7 are arranged at intervals along the length of the kiln car 1; the sensing element 4 is installed below the corresponding blocking part 6 as required and is paired with the corresponding blocking part 6.

[0043] Specifically, in this embodiment, the top of the sensing element 4 is provided with a clamping part 8. After the clamping part 8 passes through the spacer holes 7 on both sides of the blocking part 6 corresponding to the sensing element 4, it clamps the mounting base 1, thereby making the sensing element 4 detachably mounted on the mounting base 1.

[0044] Specifically, in this embodiment, the bottom of the mounting base 1 is provided with a limiting hole 9, which can limit the corresponding sensing element 4 in the horizontal direction. It works in conjunction with the clamping part 8 to strengthen the connection between the sensing element 4 and the mounting base 1.

[0045] Specifically, in this embodiment, the wake-up element 3 is elongated, extending from one end of the binary sensing array to the other end of the binary sensing array, and the end of the wake-up element 3 near the detection device 5 protrudes from the mounting base 1.

[0046] Among them, the end of the wake-up element 3 that is close to the detection device 5 protrudes from the mounting base 1, so that the wake-up element 3 approaches the detection device 5 first compared to the sensing element 4, thereby enabling the PLC control system to be woken up in advance.

[0047] The wake-up element 3 extends from one end of the binary sensing array to the other end, so that the detection device 5 will only detect the signal of the binary sensing array when it receives the signal from the wake-up element 3.

[0048] Specifically, in this embodiment, the detection device 5 includes a sensing element 10 and a mounting frame 11; wherein, the mounting frame 11 is installed on the kiln base surface at the kiln loading position, and the mounting frame 11 is provided with three waist holes 12 vertically distributed from top to bottom; the sensing element 10 includes three proximity switches, each electrically connected to the PLC control system, and the three proximity switches are installed in the corresponding waist holes 12 through corresponding nut assemblies, and the height is adjusted by the cooperation of the nut assemblies and the waist holes 12, so that they respectively correspond to the wake-up element 3, the auxiliary sensing structure and the sensing element 4 on the mounting base 1.

[0049] Specifically, in this embodiment, the width of the spacing hole 7 can ensure that the sensing element 4 corresponds one-to-one with the blocking part 6 above it, and there will be no signal misalignment.

[0050] In addition, the proximity switch has a sensing distance of 8mm. When the kiln car 1 moves along the track and approaches the kiln loading position, the distance between the proximity switch and the corresponding wake-up element 3, sensing element 4, and blocking part 6 is less than 8mm.

[0051] The working principle of this embodiment is as follows:

[0052] When kiln car 1 moves along the track and approaches the kiln loading position, the proximity switch corresponding to the wake-up element 3 receives the return signal of the wake-up element 3 first, thereby waking up the PLC control system. Then, the PLC control system receives the signals of the other two proximity switches and performs binary encoding recognition to finally obtain the kiln car number.

[0053] The principle behind the formation of binary encoding is as follows:

[0054] In the above, the position numbers of the eight mounting positions on the mounting base 1 for mounting the sensor 4 are 1, 2, 4, 8, 16, 32, 64, and 128, respectively.

[0055] If kiln car 1 is numbered 1, then sensor 4 is installed only at position 1, and not at other positions. The proximity switch corresponding to sensor 4 will only detect the return signal from sensor 4 at position 1. Meanwhile, the proximity switch corresponding to the auxiliary sensing structure will receive signals from the eight blocking parts 6. By comparing the timing of the signal received by the proximity switch corresponding to sensor 4 with the timing of the signals from the eight blocking parts 6 received by the proximity switch of the auxiliary sensing structure, it can be determined which position of sensor 4 the proximity switch received the return signal from. In this case, the timing of the signal received by the proximity switch corresponding to sensor 4 corresponds to the first signal from the eight blocking parts 6 received by the proximity switch of the auxiliary sensing structure, and the binary code formed on the PLC control system is 10000000.

[0056] If the kiln car number of kiln car 1 is 15, then the sensor 4 will only be installed at the installation positions numbered 1, 2, 4, and 8. The sensor 4 will not be installed at the other installation positions. The proximity switch corresponding to the sensor 4 will receive four signals, which correspond to the proximity switches at the installation positions numbered 1, 2, 4, and 8 respectively. The acquisition time of these four signals will correspond one-to-one with the first four signals of the eight blocking parts 6 returned by the proximity switch of the corresponding auxiliary sensing structure. The binary code formed on the PLC control system is 11110000.

[0057] This embodiment uses a binary recognition device (several sensors 4 + auxiliary sensing structure of mounting base 1 + detection device 5) to identify kiln car numbers based on the binary recognition principle. This solves the technical problem that "when using QR codes or images as encoding recognition devices, after long-term high-temperature corrosion and dust coverage, QR codes are easily missing, images are blurred, etc., causing unstable number recognition."

[0058] In addition, this embodiment only requires the fabrication of multiple sensing elements 4 with uniform structure, and together with the mounting base 1, a binary sensing array corresponding to the binary code of the kiln car can be formed according to the required kiln car number. Compared with the prior art, which requires the fabrication of N sand sealing plates with different hole arrays, the fabrication of this solution is more convenient.

[0059] Furthermore, when it is necessary to modify the number of kiln car 1, only the distribution of the sensing elements 4 needs to be adjusted to obtain the corresponding number, without the need to replace the sand sealing plate. During the adjustment of the distribution of the sensing elements 4, by providing a force greater than the clamping force of the clamping part 8 of the sensing elements 4, the sensing elements 4 can be removed from their original positions.

[0060] The above-described embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all changes made in accordance with the shape and principle of this utility model should be covered within the protection scope of this utility model.
