Description

Technical Field

[0001] This application relates to the field of environmental monitoring, specifically to a multifunctional environmental monitoring device. Background Technology

[0002] With the rapid development of science and technology, modern environmental monitoring technologies can now achieve precise environmental monitoring in extreme environments, such as tunnels, buildings, and rail transit stations at high altitudes or under high temperatures. The application of these technologies greatly enhances our understanding and management of complex environments, enabling us to obtain reliable data even under the most demanding conditions. By deploying various sensors, such as temperature sensors, humidity sensors, and gas detectors, we can monitor various parameters in the environment in real time, which is crucial for ensuring the safe operation of facilities, protecting personnel health, and maintaining the integrity of equipment.

[0003] However, in actual monitoring needs, the use of multiple types of sensors to collect various air quality data, and the fact that these sensors are typically deployed separately in different locations, leads to a significant problem: they cannot synchronously provide complete environmental information for the same location. Furthermore, this dispersed deployment not only results in messy wiring and affects visual aesthetics but also increases the difficulty of system maintenance, hindering centralized environmental monitoring. When sensors are distributed across various locations, not only do routine inspections become difficult, but locating the source of a problem also becomes more complex. These issues limit the effectiveness of environmental monitoring systems and impose additional costs and burdens on operation and maintenance. Summary of the Invention

[0004] To achieve the above and other related objectives, this application discloses a multifunctional environmental monitoring device, including a housing and a door, the door being rotatably connected to the housing, and multiple bases for mounting sensors being provided inside the housing.

[0005] Furthermore, the housing is detachably connected by a sliding guide rail, with the base slidably connected to the sliding guide rail.

[0006] Furthermore, ventilation holes are provided on the side of the box.

[0007] Furthermore, the ventilation opening is rotatably equipped with a cabinet door that can be adapted to the ventilation opening.

[0008] Furthermore, a wiring inlet for connecting the sensor is provided at the bottom of the enclosure.

[0009] Furthermore, an air inlet is provided at the bottom of the enclosure for convenient external environmental monitoring.

[0010] Furthermore, the enclosure is equipped with multiple power supply interfaces for powering the sensors, and these interfaces are powered by a unified external power source.

[0011] Furthermore, the housing is equipped with a terminal block for centrally collecting all sensor data.

[0012] By adopting the above technical solution, when it is necessary to monitor the surrounding environment, each sensor is installed on the base inside the box, and the sensor is powered through the power supply interface. The sensor data is collected centrally and uniformly through the terminal block. When it is necessary to move the sensor position according to actual needs, the base can be moved on the sliding rail to facilitate the adjustment of the sensor position. This allows multiple sensors to collect environmental data of the same environment synchronously. Moreover, when the sensors are arranged in a centralized manner, the wiring is relatively simple, which improves the ease of management. Attached Figure Description

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Reference Figure 1This application provides a multifunctional environmental monitoring device, including a housing 1. The housing 1 is provided with multiple bases 3 for mounting sensors. When environmental monitoring is required, various sensors are mounted on the bases 3. Various sensors can be arranged in the same environment, thereby providing data from the same location, which is beneficial for the construction of complete environmental information.

[0021] The housing 1 is equipped with a rotating door 2, the shape of which matches the opening of the housing 1. The door 2 is also equipped with a lock. When the sensor is placed inside the housing 1, the door 2 is locked, which protects the sensor inside the housing 1, reduces the damage to the sensor from the external environment, helps extend the service life of the sensor, and improves the accuracy of the data.

[0022] In this embodiment, the number and position of the bases 3 can be set by those skilled in the art according to actual usage needs. A sliding guide rail (not shown in the figure) is fixedly installed at the connection position inside the housing 1. The sliding guide rail is horizontally positioned, and the bases 3 are slidably connected to it. The figure shows multiple rows of bases 3 and multiple sliding guide rails, allowing each row of bases 3 to be connected to a sliding guide rail. Researchers can adjust the position of the sensor by moving the bases 3 on the sliding guide rail.

[0023] The enclosure 1 has two ventilation holes on its side, and it also has a rotating door 4 that matches the size of the ventilation holes. When the sensor is used to detect the environment, the opening angle can be adjusted according to the actual environmental conditions. This allows for airflow and prevents the inability to detect external environmental data inside the enclosed enclosure 1, while also maximizing the protection of the sensor from external corrosion in extreme environments.

[0024] Reference Figure 2 The bottom of the housing 1 has an elliptical air inlet 6 and a rectangular cable inlet 5. The cable inlet 5 is used for cable management of the sensor. The air inlet 6 and the ventilation opening work together to form convection inside the housing 1, which further realizes ventilation inside the housing 1 and is conducive to more accurate measurement of the external environment.

[0025] The enclosure 1 is equipped with multiple power supply interfaces for powering the sensors, and these interfaces are powered by a unified external power source. When multiple sensors are installed inside the enclosure 1, the sensors are connected to the power supply interfaces, and the external power supply interfaces are powered. This eliminates the need for each sensor to be connected to an external power source via a cable, thereby reducing the number of cables used in actual use, improving aesthetics, and reducing electrical accidents such as short circuits caused by overly complex wiring, thus increasing safety.

[0026] Reference Figure 2The housing 1 is equipped with a terminal block 7 for centrally collecting all sensor data. It can centrally and synchronously collect all sensor data, summarize and forward it to the upper-level equipment or system, and ensure that all data are collected synchronously, thereby more accurately reflecting the actual environmental conditions of the monitoring point and improving the consistency and reliability of the data.

[0027] This application provides a multifunctional environmental monitoring device. When monitoring of the surrounding environment is required, each sensor is installed on the base 3 inside the housing 1. The sensors are powered through the power supply interface, and the sensor data is collected centrally and uniformly through the terminal block 7. When the sensor position needs to be moved according to actual needs, the base 3 can be moved on the sliding guide rail to facilitate the adjustment of the sensor position. This allows multiple sensors to collect environmental data of the same environment synchronously. Furthermore, when the sensors are arranged centrally, the wiring is relatively simple, improving the ease of management.

[0031] In addition, it also includes a frequency conversion operation feedback circuit and a bypass operation feedback circuit. The frequency conversion operation feedback is connected to the normally open switch of relay KM1. When the electromagnetic coil of relay KM1 is energized, frequency conversion operation feedback is performed. The bypass operation feedback is connected to the normally closed switch of relay KM2. When the electromagnetic coil of relay KM2 is energized, bypass operation feedback is performed.

[0032] It also includes a frequency converter circuit. The three phases of the three-phase circuit are connected sequentially to the R, S, and T terminals of the frequency converter.

[0034] When the circuit is operating normally, HD is illuminated, indicating normal circuit operation. At this time, the rotary switch S is turned to the first position, and the circuit is in the start-up state. When the inverter has no fault output, the electromagnetic coil of KA1 is not energized. The PLC sends a signal to control either K1 or K2 to be energized. When K1 is closed, the electromagnetic coil of KM1 is energized, and RD1 is illuminated to indicate inverter operation and provide inverter operation feedback. When K2 is closed, the electromagnetic coil of KM2 is energized, and RD2 is illuminated to indicate bypass operation and provide bypass operation feedback. The 24V power supply powers the sensors. When the inverter malfunctions, the fault-triggered switch closes, energizing the electromagnetic coil of KA1, closing the normally open switch of KA1, and illuminating RD3 to indicate the fault.
