Description

Technical Field

[0001] This utility model relates to a vibrating wire acquisition device that enhances anti-interference capabilities, and belongs to the field of vibrating wire acquisition technology. Background Technology

[0002] Vibrating wire sensors are mainly used in automated monitoring of settlement in large structures, subways, bridges, tunnels, railways, water conservancy projects, dams, and mining subsidence areas. A vibrating wire sensor data acquisition system consists of a data transmitter, a vibrating wire reader, and a vibrating wire sensor.

[0003] Existing vibrating wire sensors still have some problems during use. According to the working principle of vibrating wire sensor data acquisition systems, under normal use, when there are interference sources nearby and the sensor cable is long, interference will occur, resulting in a deterioration in the data acquisition effect of the vibrating wire sensor and affecting the working efficiency of the data acquisition. Vibrating wire sensors have poor anti-interference ability and cannot adapt to different usage environments. Furthermore, interference can also occur during the data acquisition process of vibrating wire sensors when transmitting data through cables. Utility Model Content

[0004] The purpose of this invention is to provide a vibrating wire sensor acquisition device with enhanced anti-interference capabilities. This invention features a simple structure and ease of use, significantly improving the anti-interference ability of the vibrating wire sensor to adapt to measurement environments with interference and ensuring accurate and reliable data acquisition. Without significantly increasing installation complexity, it guarantees the stable operation of the vibrating wire sensor in the field, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An enhanced anti-interference vibrating wire acquisition device includes a vibrating wire sensor reader, both ends of which are connected to waterproof connectors. One end of each waterproof connector is connected to a data cable. An anti-interference sleeve is fitted over the surface of the data cable. Anti-interference filler is installed in a groove on the surface of the anti-interference sleeve. A protective sleeve is fitted over the surface of the anti-interference sleeve. A reinforcing steel plate is installed inside the protective sleeve. Reinforcing filler is installed in a groove on the surface of the protective sleeve. A stainless steel waterproof shell is fitted over the surface of the vibrating wire sensor reader.

[0007] Furthermore, the circuit board inside the vibrating wire sensor reader is encapsulated using potting technology.

[0008] Furthermore, the data cable is connected using an RS communication interface, and the data cable is up to 500 meters long.

[0009] Furthermore, the vibrating wire sensor reader consists of components such as the stainless steel waterproof housing, waterproof connector, signal excitation measurement circuit board, power supply and RS communication interface, and vibrating wire sensor interface.

[0010] Furthermore, the anti-interference sleeve is a wave-absorbing layer made of ferrite material.

[0011] Furthermore, the anti-interference filler is made of aluminum foil material.

[0012] Furthermore, the reinforcing filler is made of tensile-resistant cotton yarn.

[0013] The beneficial effects of this utility model are:

[0014] (I) This utility model incorporates a vibrating wire sensor reader. The vibrating wire sensor reader features a stainless steel waterproof housing, waterproof connectors, and an internal circuit board potting technology. This allows the reader to be installed close to the sensor, effectively shortening the vibrating wire sensor cable length and reducing interference introduced by the cable. The stainless steel waterproof housing and waterproof connectors provide waterproof protection for the vibrating wire sensor reader. Furthermore, the longer the data cable, the less interference there is, resulting in a higher excitation success rate and further improving the anti-interference performance of the vibrating wire sensor reader. The anti-interference sleeve covering the data cable provides anti-interference protection, preventing interference during data transmission. The anti-interference filler inside the anti-interference sleeve fills the gap between the sleeve and the data cable, making it more compact and further improving the anti-interference capability of the data cable. The protective sleeve covering the anti-interference sleeve protects the data cable from damage during use. The reinforced steel plate and reinforced filler extend the service life of the data cable, allowing for extended use. This significantly improves the anti-interference capability of the vibrating wire sensor reader, enabling it to adapt to interference-prone measurement environments and ensuring accurate and reliable data acquisition. Without significantly increasing installation complexity, the vibrating wire sensor reader ensures stable operation in the field, allowing it to be installed close to the sensor, effectively shortening the data cable length and reducing interference introduced by the data cable.

[0015] (II) This utility model, by setting up a vibrating wire sensor reading instrument, can achieve the anti-interference effect by using anti-interference filler and anti-interference sleeve to absorb waves again. This multi-stage wave absorption and anti-interference treatment enhances the anti-interference effect of the data cable during use, making the data cable more stable and smooth during use. The reinforced filler, made of tensile cotton yarn braid, can enhance the strength of the data cable and improve its anti-torsion effect, preventing the data cable from twisting during use and causing internal cable breakage. This design realizes a small, waterproof, and anti-interference vibrating wire sensor reading instrument, increasing the applicability of the vibrating wire sensor reading instrument when there is interference.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Example 1 Figures 1-4 This utility model provides a technical solution:

[0024] An enhanced anti-interference vibrating wire acquisition device includes a vibrating wire sensor reader 1, with waterproof connectors 2 connected to both ends of the vibrating wire sensor reader 1. A data cable 3 is connected to one end of the waterproof connector 2. An anti-interference sleeve 4 is fitted on the surface of the data cable 3. An anti-interference filler 5 is installed in a groove on the surface of the anti-interference sleeve 4. A protective sleeve 6 is fitted on the surface of the anti-interference sleeve 4. A reinforcing steel plate 7 is installed inside the protective sleeve 6. A reinforcing filler 8 is installed in a groove on the surface of the protective sleeve 6. A stainless steel waterproof shell 9 is fitted on the surface of the vibrating wire sensor reader 1.

[0025] Specifically, such as Figure 1 As shown, the circuit board inside the vibrating wire sensor reader 1 is encapsulated using potting technology. The data cable 3 is connected via an RS485 communication interface, and the data cable 3 has a maximum length of 500 meters. The vibrating wire sensor reader 1 consists of a stainless steel waterproof shell 9, a waterproof connector 2, a signal excitation measurement circuit board, a power supply and RS485 communication interface, a vibrating wire sensor interface, and other components.

[0026] In this implementation scheme: a vibrating wire sensor reader 1 is installed. The vibrating wire sensor reader 1 is designed with a stainless steel waterproof housing 9, a waterproof connector 2, and an internal circuit board potting technology. This allows the reader to be installed close to the sensor, effectively shortening the length of the vibrating wire sensor cable and reducing interference introduced by the cable. The stainless steel waterproof housing 9 and the waterproof connector 2 provide waterproof protection for the vibrating wire sensor reader 1. Furthermore, the longer the data cable 3, the less interference there is, resulting in a higher excitation success rate and further improving the anti-interference performance of the vibrating wire sensor reader 1. The anti-interference sleeve 4 covering the surface of the data cable 3 provides anti-interference protection for the data cable 3. To prevent interference during data cable 3 transmission, the anti-interference sleeve 4 contains anti-interference filler 5 that fills the gap between the sleeve and the data cable 3, making it tighter and further improving the anti-interference capability of the data cable 3. The protective sleeve 6 on the surface of the anti-interference sleeve 4 protects the data cable 3 from damage during use, and the reinforcing steel plate 7 and reinforcing filler 8 extend the service life of the data cable 3, allowing it to be used for extended periods. This significantly improves the anti-interference capability of the vibrating wire sensor reader 1, enabling it to adapt to interference-prone measurement environments and ensuring accurate and reliable data acquisition. Without significantly increasing installation complexity, this method ensures stable operation of the vibrating wire sensor reader 1 in the field, allowing it to be installed close to the sensor, effectively shortening the length of the data cable 3 and reducing interference introduced by the data cable 3.

[0027] Please refer to Example 2 Figure 1 , Figure 2 and Figure 4The difference between this embodiment and embodiment 1 is that the anti-interference sleeve 4 is a wave-absorbing layer made of ferrite material, and the anti-interference filler 5 is made of aluminum foil material.

[0028] Specifically, such as Figure 1-4 As shown, the reinforcing filler 8 is made of tensile-resistant cotton yarn.

[0029] In this implementation scheme: by setting up a vibrating wire sensor reading instrument 1, the anti-interference filler 5 and the anti-interference sleeve 4 can absorb waves again to achieve the anti-interference effect. This multi-stage wave absorption and anti-interference treatment enhances the anti-interference effect of the data cable 3 during use, making the data cable 3 more stable and smooth during use. The reinforcing filler 8 uses tensile cotton thread braiding to enhance the strength of the data cable 3 and improve the anti-torsion effect of the data cable 3, preventing the data cable 3 from twisting during use and causing internal cable breakage. This design realizes a small, waterproof, anti-interference vibrating wire sensor reading instrument 1, increasing the applicability of the vibrating wire sensor reading instrument 1 when there is interference.
