[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0025] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides an environment monitoring device 1, including a control circuit board 11, and a data acquisition unit, a data processing unit and a data transmission unit 14 arranged on the control circuit board 11; the data acquisition unit is used to acquire detection data of the monitored environment, the data processing unit is used to process and analyze the detection data and obtain analysis data, and the data transmission unit 14 is used to transmit the analysis data to the background; wherein, the data acquisition unit includes a sensor component 12, the data processing unit includes a single-chip microcontroller 13, and the sensor component 12, the single-chip microcontroller 13 and the data transmission unit 14 are all electrically connected through the control circuit board 11.

[0026] The sensor assembly 12 obtains the detection data of the monitoring environment, and the single-chip microcontroller 13 compares and analyzes the detection data with the normal standard value to obtain the analysis data, and transmits the analysis data to the background through the data transmission unit 14, which not only enables the staff to remotely monitor and obtain the data of the environmental influencing factors of the power equipment in real time, but also can predict the development trend of the environmental influencing factors through the analysis data, so as to achieve the purpose of early warning. In addition, the remote monitoring working mode can ensure the normal operation of the power equipment while avoiding the threat to the personal safety of the staff.

[0027] Further, see Figure 2The data transmission unit 14 includes a sensor register address dial 141, an RS485 transmission module 142 and a data transmission terminal 143; the sensor register address dial 141 and the RS485 transmission module 142 are electrically connected through the control circuit board 11, and the RS485 transmission module 142 and the data transmission terminal 143 are connected.

[0028] The sensor register address dial 141 can control the change of the sensor type for data transmission, that is, it can control the specific items of the monitored environmental influencing factors; and the RS485 communication protocol is used for data transmission. Since the RS485 communication protocol uses a balanced transmission and differential reception transmission form, the RS485 transmission module 142 has good anti-interference ability and long-distance transmission capability, so that the environmental monitoring device 1 has better data transmission capability.

[0029] Further, see Figure 2 The environmental monitoring device 1 also includes a power module 15 electrically connected to the control circuit board 11, and the power module 15 includes a power control port 151 and a power transmission terminal 152 connected to each other. The power transmission terminal 152 is connected to the power line, and the power control port 151 can protect the environmental monitoring device 1 from damage to electronic components due to unstable current and voltage. In practical applications, the specifications of the corresponding power transmission terminal 152 and the power output port can be selected according to the design requirements or application requirements of the product.

[0030] Furthermore, if Figure 2 As shown, the environment monitoring device 1 also includes a status indication module 16 electrically connected to the control circuit board 11, and the status indication module 16 includes a status output port 161 and a status indicator light 162 connected to each other. The status indicator light 162 allows the staff to intuitively obtain the working status of the environment monitoring device 1, so as to facilitate the installation and maintenance of the environment monitoring device 1.

[0031] Further, see Figure 1 and Figure 3 The environmental monitoring device 1 further includes a housing 17, which is surrounded by an installation cavity 173, and the control circuit board 11, the data acquisition unit, the data processing unit and the data transmission unit 14 are all arranged in the installation cavity 173. The housing 17 has a certain structural strength and impact resistance, and can protect the control circuit board 11, the data acquisition unit, the data processing unit and the data transmission unit 14, so that the environmental monitoring device 1 has a stable working state.

[0032] In actual production applications, the material of the housing 17 can be selected according to product design requirements. In the embodiment of the present application, the material of the housing 17 is preferably aluminum alloy. On the one hand, compared with common metal materials such as carbon steel, aluminum alloy has better specific strength and plastic processing properties, so that the housing 17 has good structural strength and is easy to process.

[0033] Furthermore, if Figure 3 and Figure 4 As shown, the housing 17 includes a housing body 171 and a cover plate 172 covering both sides of the housing body 171; the inner wall of the housing body 171 is correspondingly provided with a mounting groove 1711, and the control circuit board 11 is installed in the mounting groove 1711. The arrangement of the housing body 171 and the cover plate 172 can facilitate the installation and maintenance of internal components, and the mounting groove 1711 can not only facilitate the installation and positioning of the control circuit board 11, but also play a role in limiting the control circuit board 11, so as to protect the control circuit board 11.

[0034] Further, see Figure 3 The cover plate 172 is provided with a fixing hole 1721, and the interior of the shell body 171 is provided with a fixing groove 1712 corresponding to the fixing hole 1721. The fastener passes through the fixing hole 1721 and is installed in the fixing groove 1712 to connect the cover plate 172 with the shell body 171. The cooperation between the fixing hole 1721, the fixing groove 1712 and the fastener forms a detachable connection with good connection strength between the cover plate 172 and the shell body 171, making it easy to install and maintain the cover plate 172 and the shell body 171.

[0035] Specifically, Figure 3 As shown, the cover plate 172 is provided with a plurality of air inlet holes 1722. The air inlet holes 1722 allow external air to enter the shell body 171, which not only enables the sensor assembly 12 to obtain the test sample, but also enables the heat generated by the electrical components inside the environment monitoring device 1 to be dissipated in time when working, so as to ensure that the environment monitor can work normally.

[0036] Further, see Figure 4 The outer ring of the shell body 171 is provided with a fixed engaging member 1713, and the fixed engaging member 1713 includes a groove portion 17132 and an extension portion 17131 connected to each other. In practical applications, a clamping structure that cooperates with the fixed engaging member 1713 can be provided at a position where the environment monitoring device 1 needs to be fixedly installed, so that the environment monitoring device 1 can be stably fixed and detachably installed.

[0037] In an optional embodiment, the sensor assembly 12 includes at least one of a gas sensor, a temperature and humidity sensor, and a water level sensor. In actual production applications, the gas sensors can all adopt solid-state electrochemical sensor technology. Since the high-humidity resistant solid polymer electrolyte material has very low water absorption, the precise and compact design prevents a large amount of water molecules from entering, and the sensor assembly 12 can work normally and continuously in an environment with a humidity of more than 95% for a long time, so that the sensor assembly 12 can have a long service life and good environmental adaptability.

[0038] In an optional embodiment, the gas sensor may include a sulfur hexafluoride (SF6) sensor, an oxygen sensor, an ozone sensor, a methane sensor, a carbon monoxide sensor, a carbon dioxide sensor, etc. In actual production applications, the type and quantity of gas sensors can be selected as needed, and a single type of gas sensor can be used, or a plurality of gas sensors can be integrated.

[0039] Among them, some gas sensors can use non-dispersive infrared (NDIR) sensor technology without light pool. Non-dispersive infrared absorption (NDIR) is an optical gas detection method based on gas absorption theory. After the infrared radiation emitted by the infrared light source is absorbed by the gas to be measured at a certain concentration, the light intensity at a specific wavelength will change in a manner related to the gas concentration. Therefore, the gas concentration can be calculated based on the change in light intensity. The sensor measurement and control system can directly obtain the concentration of the measured gas by collecting infrared output signals and measuring standard gas curves using a nonlinear correction algorithm. By adopting the above technologies, compared with traditional sensor types, NDIR sensors have a simpler structure, lower power consumption and lower production costs. At the same time, NDIR sensors can be modularized and standardized, and can achieve high production in a short time, which is conducive to large-scale promotion and application. In addition, due to the different absorption wavelengths of different gases, NDIR sensors also have strong anti-interference capabilities.

[0040] Among them, the oxygen sensor can use galvanic cell sensor technology and perform measurements based on the galvanic cell principle. When oxygen passes through the electrolyte, a redox reaction occurs at the cathode and anode, ionizing the anode metal and releasing electrons. The magnitude of the current is proportional to the concentration of oxygen. In addition, the galvanic cell oxygen sensor will also add a temperature compensation circuit to correct the effect of temperature on the current, so the galvanic cell oxygen sensor can improve the accuracy of oxygen measurement.

[0041] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
