Description

Technical Field

[0001] This utility model relates to the technical field of identification equipment, and in particular to a device that can reliably identify the number of a kiln car in motion. Background Technology

[0002] With increasing demands for kiln process flow and product quality, traditional tunnel kiln cars, lacking kiln car numbers and unable to clearly indicate product loading and material tracking, no longer meet the requirements. Numbering kiln cars to know which car a product is loaded onto upon entering the kiln and its loading status has become standard practice. Kiln cars operate in high-temperature and dusty environments, and QR code or image-based encoding and identification devices are prone to issues such as missing QR codes and blurred images after long-term high-temperature corrosion and dust accumulation, leading to unstable numbering and identification. While Chinese patent number 202320224482.3, entitled "Tunnel Kiln Car Numbering Identification Device," discloses an identification scheme combining a front and rear detection element positioning device and a binary identification code detection device, this binary identification code detection device consists of binary identification code detection holes and binary identification code detection elements. The binary identification code detection holes are set on the sand sealing plate of the kiln car, forming different hole arrays. If the kiln car number is 1-100, then 100 sand sealing plates with different hole arrays are needed, making the manufacturing process quite cumbersome. Furthermore, when the kiln car number needs to be changed, the sand seal plate must be replaced. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device that can reliably identify the number of a kiln car in motion.

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

[0005] A device capable of reliably identifying the number of a kiln car in motion includes a kiln car, a mounting base, a wake-up module, several sensors, a binary sensor array detection device, and a PLC control system.

[0006] The mounting base is located at the front end of the kiln car;

[0007] The wake-up module is installed on the mounting base;

[0008] Several sensors are detachably mounted on the mounting base according to the specific kiln car number, forming a corresponding binary code;

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

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

[0011] In this technical solution, when the kiln car approaches the kiln loading position, the PLC control system is activated by the wake-up module. Then, the PLC control system receives the signal from the binary induction array detection device and performs binary code recognition. This technical solution uses a binary recognition device (several sensors + binary induction array detection device) to identify the kiln car number using the binary recognition principle, which can solve 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 sensing array corresponding to the binary code of the kiln car number. Compared with the existing technology that requires the fabrication of N sand sealing plates with different hole arrays, this solution is more convenient to manufacture.

[0013] Furthermore, the mounting base is provided with a symmetrical support structure;

[0014] The support structure is provided with a mounting groove;

[0015] The two ends of the sensing element are respectively inserted into the corresponding mounting slots.

[0016] Furthermore, the sensing element includes a sensing body and a connecting rod;

[0017] The sensing body is connected to the mounting base via connecting rods located at both ends and snapped into corresponding mounting slots.

[0018] Furthermore, the sensing body is fixedly connected to the connecting rod.

[0019] Furthermore, the sensing body is sleeve-shaped and has a spring inside;

[0020] The connecting rod has a limiting part at the end away from the mounting groove. This end is inserted into the sensing body and contacts the end corresponding to the spring. The connecting rod also has a force-bearing part.

[0021] Furthermore, the mounting base is in the shape of a "∏".

[0022] Furthermore, the mounting groove is provided with a turning structure.

[0023] Furthermore, the mounting slot is shaped like a "Г".

[0024] Furthermore, the binary sensing array detection device includes a detection element and a mounting bracket;

[0025] The detection 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.

[0026] Furthermore, the detection element includes multiple proximity switches, which correspond to the mounting positions of the wake-up module and the sensors on the mounting base, respectively.

[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, the PLC control system is activated by the wake-up module. Then, the PLC control system receives the signal from the binary induction array detection device and performs binary encoding recognition to finally obtain the kiln car number. This technical solution uses a binary recognition device (several sensors + binary induction array detection device) to identify the kiln car number based on the binary recognition principle, which can solve the technical problem that "when using QR codes or images for encoding recognition, after long-term high-temperature corrosion and dust coverage, QR codes are easily missing, images are blurred, etc., causing unstable number recognition".

[0029] 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 sensing array corresponding to the binary code of the kiln car number. Compared with the existing technology that requires the fabrication of N sand sealing plates with different hole arrays, this solution is more convenient to manufacture.

[0030] Moreover, when it is necessary to change the kiln car number, only the distribution of the sensing elements needs to be adjusted to obtain the corresponding number, without the need to replace the sand sealing plate. Attached Figure Description

[0041] The present invention will be further described below with reference to two specific embodiments:

[0042] Example 1

[0043] like Figures 1 to 4 As shown in the figure, the device for stably identifying the number of a kiln car in motion described in this embodiment includes a kiln car 1, two mounting bases 2, a wake-up module 3, several sensors 4, a binary sensor array detection device 5, and a PLC control system.

[0044] The binary induction array detection device 5 is installed on the kiln base surface at the kiln loading position; the PLC control system is electrically connected to the binary induction array detection device 5.

[0045] Both mounting bases 2 are located at the front end of the kiln car 1 and close to both sides respectively; several sensors 4 are detachably mounted on the two mounting bases 2 according to the specific kiln car number, forming a binary sensing array with binary code corresponding to the kiln car number; the wake-up module 3 is fixedly mounted on the mounting base 2 (close to the binary sensing array detection device 5) and located at the front end of the mounting base 2 (ensuring that the wake-up module 3 approaches the binary sensing array detection device 5 first compared to the sensors 4, so that the PLC control system can be woken up in advance).

[0046] Specifically, in this embodiment, the mounting base 2 is in the shape of "∏", and its symmetrical support structure is provided with mounting grooves 6, which are in the shape of "Г".

[0047] Specifically, in this embodiment, the sensing element 4 includes a sensing body 7 and a connecting rod 8; the sensing body 7 is fixedly connected to the connecting rod 8 located at both ends thereon, and is installed and connected to the mounting base 2 by the connecting rod 8 being inserted into the corresponding mounting groove 6 from the inlet of the mounting groove 6. Figure 4(Point A in the diagram is the inlet of mounting slot 6). When it is necessary to remove the sensor 3, the connecting rod 8 is pulled out of the mounting slot 6 in the opposite direction to remove the sensor 3 from the mounting base 2.

[0048] Specifically, in this embodiment, the binary induction array detection device 5 includes a detection element 10 and a mounting bracket 11. The detection element 10 is mounted on the kiln base surface at the kiln loading position via the mounting bracket 11 and is electrically connected to the PLC control system. In addition, the detection element 10 includes nine proximity switches, one of which corresponds to the installation position of the wake-up module 3 and works with the wake-up module 3 to wake up the PLC control system. The other eight proximity switches correspond to eight installation positions for mounting the sensing elements 4.

[0049] like Figure 1 As shown, in this embodiment, the four mounting positions for mounting the sensors 4 on the two mounting bases 2 are arranged neatly from top to bottom. The interval between the mounting position of the wake-up module 3 and the adjacent mounting position of the sensor 4, as well as the interval between the mounting positions of the adjacent sensors 4, ensures that the proximity switch can only receive the return signal of the wake-up module 3 or sensor 4 installed at the corresponding mounting position.

[0050] Specifically, in this embodiment, the sensing distance of the proximity switch is 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 module 3 or sensing element 4 is less than 8mm, while the distance between the proximity switch and the mounting base 2 is greater 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 wake-up module 3 receives the return signal from wake-up module 3 first, thereby waking up the PLC control system. Then, the PLC control system receives the signals from the other eight 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 eight mounting positions for installing the sensor 4 on the two mounting bases 2 are numbered 1, 2, 4, 8, 16, 32, 64, and 128 respectively. If the kiln car number of kiln car 1 is 1, then the sensor 4 is only installed at the mounting position numbered 1, and the sensor 4 is not installed at the other mounting positions. In the binary induction array detection device 5, only the proximity switch corresponding to the mounting position numbered 1 receives the signal, and the binary code formed on the PLC control system is 10000000. If the kiln car number of kiln car 1 is 15, then the sensor 4 is only installed at the mounting positions numbered 1, 2, 4, and 8, and the sensor 4 is not installed at the other mounting positions. In the binary induction array detection device 5, only the proximity switch corresponding to the mounting positions numbered 1, 2, 4, and 8 receives the signal, and the binary code formed on the PLC control system is 11110000.

[0055] This embodiment uses a binary recognition device (several sensors 4 + binary sensor array 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."

[0056] In addition, this embodiment only requires the fabrication of multiple sensing elements 4 with uniform structure, and together with the mounting base 2, 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.

[0057] Moreover, when it is necessary to modify the number of kiln car 1, only the distribution of the sensing element 4 needs to be adjusted to obtain the corresponding number, without the need to replace the sand sealing plate.

[0058] Example 2

[0059] like Figures 5 to 7 As shown, compared with Embodiment 1, in this embodiment of the device for stably identifying the number of a kiln car in motion, the sensing body 7 of the sensing element 4 is sleeve-shaped, and a spring 9 is provided inside; the end of the connecting rod 8 away from the mounting groove 6 is provided with a limiting part 12, which is inserted into the sensing body 7 and contacts the end corresponding to the spring 9, and the connecting rod 8 is provided with a force-receiving part 13. The mounting groove 6 is a straight groove. The limiting part 12 is used to prevent the connecting rod 8 from separating from the sensing body 7.

[0060] When the sensor 4 needs to be installed, first press one of the connecting rods 8A toward the sensing body 7 (the spring 9 is in a compressed state) to adjust the overall length of the sensor 4. Then, insert the other connecting rod 8B into the corresponding straight groove (the connecting rod 8A is already aligned with its corresponding straight groove). Then release the pressure on the connecting rod 8A. Under the force of the spring 9, the connecting rod 8A is easily inserted into its corresponding straight groove, thereby installing the sensor 4 on the mounting base 2.

[0061] When it is necessary to disassemble the sensor 4, press your finger against the force-receiving part 13 and squeeze the connecting rod 8 corresponding to the force-receiving part 13 toward the sensing body 7. Adjust the overall length of the sensor 4, and the sensor 4 can be removed from the mounting base 2.

[0062] 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.
