Description

Technical Field

[0001] This utility model relates to the field of data acquisition, specifically to a data acquisition terminal for monitoring high formwork support. Background Technology

[0002] High-rise formwork (or large-scale formwork) refers to concrete formwork support projects erected at construction sites for buildings and municipal infrastructure with a height of 8m or more, a span of 18m or more, a total construction load (design value) of 15kN / ㎡ or more, or a concentrated line load (design value) of 20kN / m or more. Before and during high-rise formwork construction, a monitoring system needs to be installed in the support system for real-time safety monitoring.

[0003] Existing monitoring systems typically consist of a data acquisition terminal and a platform terminal. The data acquisition terminal uses displacement sensors, tilt sensors, and pressure sensors installed in the support system to collect data in real time for various monitoring items. The platform terminal is mainly used for summarizing, displaying, and processing the collected data. Due to the limitations of the construction site environment, the data from the acquisition terminal usually needs to be transmitted through a data acquisition terminal that is networked with multiple sensors. In other words, the data acquisition terminal (acquisition and transmission terminal) provides the communication link between the acquisition terminal and the platform terminal.

[0004] Current data acquisition terminals generally have a large overall structure and scattered external components, resulting in complex on-site installation and maintenance operations as well as poor aesthetics. In addition, the assembly of various modules inside the terminal is relatively complex, resulting in poor integration. Utility Model Content

[0010] According to a specific embodiment of the present invention, a lamp hole mounting position is provided on the front side wall of the front housing, and the indicator light of the control circuit board extends out through the lamp hole mounting position.

[0011] According to a specific embodiment of the present invention, a mounting platform is provided at the rear opening of the front housing, and a waterproof groove is provided on the mounting platform along the circumference of the rear opening, and the waterproof groove is coated with sealant.

[0012] Furthermore, the rear cover plate has an annular protrusion corresponding to the waterproof groove, which extends into the waterproof groove during installation.

[0013] Furthermore, the mounting platform has an adhesive reservoir near the waterproof groove, and the adhesive reservoir has an inclined bottom.

[0014] According to a specific embodiment of the present invention, the mounting fastener includes a base plate and a set of fastening arms, which are used to clamp onto the formwork support crossbar or upright; wherein, the base plate is square and has four fixing holes, and the rear cover plate has four connecting holes, and the base plate is connected to the connecting holes by screws that pass through the four fixing holes respectively.

[0015] Furthermore, the four fixed holes are distributed at the four corners of the square.

[0016] This invention offers the following advantages: It provides a rectangular data acquisition terminal with a regular overall shape and good aesthetics. Furthermore, the external components of the control circuit board (external charging port, control switch, and antenna interface) are located on the upper side wall of the front housing, i.e., on the same side of the terminal, making on-site installation and maintenance more convenient and improving the overall structural harmony. Additionally, the interior of the front housing is partitioned, with the upper and lower accommodating slots independently mounting the control circuit board and battery pack, respectively, preventing interference between them.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Many specific details are set forth in the following description with reference to the embodiments in order to provide a full understanding of this utility model; however, it should be understood that the following embodiments and detailed descriptions are for illustrative purposes only and do not limit the scope of protection of this utility model.

[0028] The data acquisition terminal in this embodiment can be used as a transmission end in a high-support formwork monitoring system. On-site, it receives data from multiple sensors using wireless communication methods such as LoRa, ZigBee, or UNB, and uploads the received data to a platform for processing via network communication technologies such as 4G. The data acquisition terminal, for example... Figure 1-4 As shown, it includes a housing 10, a control circuit board 20, a battery pack 30, an external antenna assembly 40, and a mounting fastener 50.

[0029] The outer casing 10 includes a front casing 11 and a rear cover plate 12. The front casing 11 is in the shape of a cuboid container, and the length of its short side is set to not exceed 80% of the length of its long side. Further, the length of the short side is set to exceed 50% of the length of its long side, for example, the length of the long side is 30cm and the length of the short side is 20cm. Among them, multiple edges of the front casing 11 are chamfered, which can weaken the sharpness of the edges and corners and avoid accidentally injuring the staff during disassembly and assembly.

[0030] The front housing 11 has a rear opening 13, and the rear cover 12 is a flat plate with the same shape as the front housing 11. It is removably installed on the front housing 11 and seals the rear opening 13; for example, the rear cover 12 is fixed to the front housing 11 by several locking bolts. Specifically, a mounting platform 14 is provided at the rear opening 13 of the front housing 11, and a waterproof fitting structure is provided at the mounting platform 14 to ensure the waterproof effect of the connection gap between the front housing 11 and the rear cover 12.

[0031] like Figure 7-8 As shown, in this embodiment, the mounting platform 14 has a waterproof groove 141 along the circumference of the rear opening 13. The waterproof groove 141 is coated with sealant. When the rear cover plate 12 is installed, the waterproof groove 141 is filled with sealant to form a good waterproof seal. The depth of the waterproof groove 141 is, for example, 3-5 mm.

[0032] Preferred, such as Figure 9 As shown, the rear cover plate 12 is provided with an annular protrusion 121 corresponding to the waterproof groove 141. During installation, the annular protrusion 121 extends into the waterproof groove 141. Preferably, the annular protrusion 121 and the waterproof groove 141 are fitted with a gap, which is conducive to the rapid positioning of the rear cover plate 12 during installation and also conducive to forming a better sealing effect.

[0033] For further selection, please refer to [link / reference]. Figure 8 The mounting platform 14 has an adhesive-containing groove 142 near the waterproof groove 141. The adhesive-containing groove 142 has an inclined bottom, which helps to accommodate more sealant between the edge of the rear cover plate 12 and the mounting platform 14, thereby improving the effectiveness of the seal.

[0034] like Figure 5-6As shown, the front housing 11 has a partition plate 15 extending in the same direction along its long side inside. The partition plate 15 divides the internal space of the front housing 11 and forms an upper receiving groove 16 and a lower receiving groove 17. The battery pack 30 is installed in the lower receiving groove 17, and the control circuit board 20 is installed in the upper receiving groove 16. The number of control circuit boards 20 can be one or more, depending on the actual design requirements. The figure shows one control circuit board 20 as an example. Multiple fixing posts 161 are provided in the upper receiving groove 16. The control circuit board 20 is fixedly assembled by screws onto the fixing posts 161. It should be noted that the circuit board's programming and communication protocol can be burned according to the design requirements, and this is not limited here and will not be elaborated on.

[0035] Please see Figure 4 The upper sidewall of the front housing 11 is provided with multiple mounting holes 111. The external charging port 21, control switch 22, and antenna interface 23 of the control circuit board 20 are correspondingly installed into different mounting holes 111. The external antenna in the external antenna group 40 can be detachably installed onto the antenna interface 23. Preferably, the multiple mounting holes 111 are linearly spaced along the long side of the front housing 11.

[0036] The number of antenna interfaces 23 can be more than two, such as four, or three or five as needed; the external charging port 21 and the control switch 22 are located on opposite sides of the antenna interfaces 23, which makes them easy to distinguish and operate. Correspondingly, the front housing 11 and the rear cover 12 are both made of metal. Corresponding markings can be engraved on the upper side wall of the front housing 11 at the different mounting holes 111 using laser marking.

[0037] like Figure 2 and Figure 7 As shown, a labeling slot 112 is provided in the middle of the lower side wall of the front housing 11. A labeling sticker is attached to the labeling slot 112. The labeling sticker may contain product or company logo and other identification information.

[0038] The front side wall of the front housing 11 is provided with a lamp hole mounting position 113, and the indicator light of the control circuit board 20 extends out through the lamp hole mounting position 113; Figure 7 The illustration shows a case with two lamp hole mounting positions 113, but in other embodiments, a greater number of lamp hole mounting positions 113 may be provided.

[0039] Mounting fastener 50 is installed on the outside of the rear cover plate 12, mainly used to install the entire equipment into a suitable position within the formwork system. For example... Figure 3-4 , Figure 9As shown, the mounting fastener 50 includes a base plate 51 and a set of fastener arms 52. The fastener arms 52 are provided with locking members 53. The fastener arms 52 and locking members 53 are used to fasten to the crossbar or upright of the formwork support. The base plate 51 is square and has four fixing holes 511. The rear cover plate 12 is provided with four connecting posts 122. The connecting posts 122 are used to provide connecting holes. The base plate 51 is connected to the connecting holes by screws that pass through the four fixing holes 511 respectively.

[0040] Furthermore, the four fixing holes 511 are distributed at the four corners of the square, which allows the buckle arm 52 to have more installation directions, for example in... Figure 3 Based on the above, it is rotated 90° for installation. This allows for flexible adjustment of the installation position according to the site conditions, and has the advantages of greater flexibility and practicality.

[0041] Although the present invention has been described above through embodiments, the above embodiments are only used to exemplarily describe possible implementations of the present invention, and are not intended to limit the scope of protection of the present invention. Any equivalent substitutions or changes made by those skilled in the art in accordance with the present invention should also be covered by the scope of protection defined by the claims of the present invention.
