Description

Technical Field

[0001] This utility model relates to the field of sensor technology, specifically to a vibration sensor that integrates noise, temperature, and harmful gas measurements. Background Technology

[0002] Vibration sensors are mainly used to detect the vibration information of objects. They can convert mechanical signals into electrical signals and output them, making vibration sensors widely used in process and / or automation technologies.

[0003] In existing technologies, vibration sensors are typically mounted on the surface of equipment. During operation, these sensors collect the frequency and amplitude of vibrations generated by the equipment and convert this data into electrical signals for output, thus completing data collection and transmission. However, when rotating machinery malfunctions, it can cause increased vibration levels, abnormal noise, and even elevated operating temperatures. These malfunctions can damage sealing components and other parts, and in severe cases, lead to leakage of the internal working medium. If the working medium is a harmful gas, it can pollute the surrounding environment and endanger the safety of personnel involved in the operation and maintenance of nearby equipment. Therefore, equipment monitoring requires simultaneous monitoring of vibrations, sound, temperature changes, and the presence of harmful gases. Since these various changes require corresponding sensors, they must be installed on the equipment surface, leading to low installation efficiency. Utility Model Content

[0004] In view of this, the present invention provides a vibration sensor that integrates noise, temperature and harmful gas measurements to solve the problem that various changes generated during equipment operation require monitoring by various corresponding sensors, which necessitates the sequential installation of these sensors on the surface of the equipment, resulting in low sensor installation efficiency.

[0005] In a first aspect, this utility model provides a vibration sensor that integrates noise, temperature, and harmful gas measurements, comprising:

[0006] A housing, the housing being adapted to be mounted on the device to be tested and having a mounting cavity;

[0007] The sensing assembly includes a vibration sensing unit, a noise sensing unit, a temperature sensing unit, and a gas sensing unit. The vibration sensing unit, the noise sensing unit, the temperature sensing unit, and the gas sensing unit are all disposed within the mounting cavity and are spaced apart from each other.

[0008] A control component is disposed within the mounting cavity and is electrically connected to the sensing component and an external server to receive vibration data, noise data, temperature data, and gas data of the device under test detected by the sensing component, and transmit the received vibration data, noise data, temperature data, and gas data to the external server.

[0009] Beneficial effects: By integrating the vibration sensing unit, noise sensing unit, temperature sensing unit, and gas sensing unit into the housing, when it is necessary to detect the vibration, noise, temperature, and presence of harmful gases of the device under test, it is not necessary to install the corresponding sensors sequentially. Instead, the sensors in this embodiment can be installed on the outer surface of the device under test to detect the vibration, noise, temperature, and presence of harmful gases. This improves the installation efficiency of the sensors and avoids the wiring problems caused by installing multiple sensors at the same time.

[0010] In one optional embodiment, the system further includes a plurality of partitions, all of which are spaced apart within the mounting cavity to divide the mounting cavity into a plurality of receiving cavities, wherein the vibration sensing unit, the noise sensing unit, the temperature sensing unit, the gas sensing unit, and the control component are respectively disposed within one of the receiving cavities.

[0011] Beneficial effects: By setting several partitions in the mounting cavity, which are partition plates in this embodiment, and all the partitions are spaced apart in the mounting cavity, the partitions can divide the mounting cavity into several receiving cavities when the partitions are installed in the mounting cavity. This allows the vibration sensing unit, noise sensing unit, temperature sensing unit, gas sensing unit, and control components to be respectively set in one receiving cavity, so as to avoid interference between the vibration sensing unit, noise sensing unit, temperature sensing unit, and gas sensing unit when they collect data from the device under test.

[0012] In one optional embodiment, the noise sensing unit, the gas sensing unit, and the control component are each disposed within one of the receiving cavities, and the vibration sensing unit and the temperature sensing unit are disposed within the same receiving cavity.

[0013] Beneficial effects: By placing the noise sensing unit, gas sensing unit, and control components in one housing cavity, and placing the vibration sensing unit and temperature sensing unit in the same housing cavity, it is possible to achieve the following: The noise sensing unit and gas sensing unit need to collect the sound and gas generated during the operation of the device under test. Therefore, in order to avoid interference from the sound and gas to other sensing units, the noise sensing unit and gas sensing unit need to be placed in a separate housing cavity. The vibration sensing unit and temperature sensing unit only need to contact the device to collect the vibration and temperature data generated during the operation of the device. Therefore, in order to effectively utilize the space of the mounting cavity inside the housing, the vibration sensing unit and temperature sensing unit can be installed in the same housing cavity.

[0014] In one alternative embodiment, any of the partitions is provided with a connecting portion, the connecting portion being adapted to connect two adjacent receiving cavities, so that the control component is electrically connected to the vibration sensing unit, the noise sensing unit, the temperature sensing unit, and the gas sensing unit respectively through the connecting portion.

In turn, the cables that electrically connect the control component to the vibration sensing unit, noise sensing unit, temperature sensing unit and gas sensing unit can be electrically connected to their corresponding counterparts through the connecting part.

[0016] In one optional implementation, the control component includes an electrically connected processing unit and a transmission unit.

The first collection portions are connected to the cavity and the outside, so that the sound generated by the device under test is transmitted into the cavity through the first collection portions and received by the noise sensing unit.

[0019] Beneficial effects: By opening several first collection parts on the side wall of the housing corresponding to the housing cavity where the noise sensing unit is installed, the first collection parts are first collection holes in this embodiment. The first collection parts can connect the housing cavity where the noise sensor is installed with the outside world, so that the sound generated by the device under test during operation can be transmitted into the housing cavity through the first collection parts, thereby enabling the noise sensing unit to receive the sound generated by the device under test during operation and generate it as sound data.

[0020] In one optional embodiment, a plurality of second collection sections are provided on the side wall of the housing corresponding to the gas sensing unit.

[0022] In an alternative embodiment, an applicator is also included, which is configured to apply to the inner wall surface of the mounting cavity and the outer surface of all the partitions.

[0023] Beneficial effects: By applying a coating to the inner wall of the mounting cavity and the outer surface of all the partitions, the coating, which in this embodiment is an electromagnetic wave shielding coating, can shield electromagnetic waves, thereby avoiding mutual interference between the sensing units and external interference.

[0024] In an alternative embodiment, a power supply unit is further included, which is disposed within one of the receiving cavities and is electrically connected to the sensing component and the control component to provide power to the sensing component and the control component.

[0025] Beneficial effects: By using a power supply component housed within a receiving cavity (in this embodiment, the power supply component is a power source), and being electrically connected to both the sensing and control components, the power supply component can provide power to the sensing and control components, thereby enabling them to operate normally. Specifically, the power supply component has a built-in rechargeable lithium battery that can be used with a solar-assisted power supply interface to support wireless charging (Qi protocol). It also features dynamic power consumption management and can automatically switch between sleep and operating modes based on data transmission frequency, extending battery life.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] The following is combined Figure 1 The following describes embodiments of the present invention.

[0036] According to embodiments of this utility model, in one aspect, a vibration sensor integrating noise, temperature, and harmful gas measurements is provided, such as... Figure 1 As shown, the device includes a housing 1, a sensing component 2, and a control component 3. The housing 1 is adapted to be installed on the device under test and has a mounting cavity. The sensing component 2 includes a vibration sensing unit 21, a noise sensing unit 22, a temperature sensing unit 23, and a gas sensing unit 24. The vibration sensing unit 21, noise sensing unit 22, temperature sensing unit 23, and gas sensing unit 24 are all installed in the mounting cavity and are spaced apart from each other. The control component 3 is installed in the mounting cavity and is electrically connected to the sensing component 2 and an external server to receive vibration data, noise data, temperature data, and gas data of the device under test detected by the sensing component 2, and transmit the received vibration data, noise data, temperature data, and gas data to the external server.

[0037] The aforementioned vibration sensor integrating noise, temperature, and harmful gas measurements utilizes a sensing component 2 and a control component 3 housed within a housing 1. The housing 1 is mountable on a device under test and has a mounting cavity. The sensing component 2 includes a vibration sensing unit 21, a noise sensing unit 22, a temperature sensing unit 23, and a gas sensing unit 24. These units are all housed within the mounting cavity and spaced apart from each other. The vibration sensing unit 21 can acquire the vibration frequency and amplitude of the device under test during operation. The noise sensing unit 22 can collect the sound generated during the operation of the device under test, the temperature sensing unit 23 can collect the temperature change during the operation of the device under test, and the gas sensing unit 24 can collect the gas generated during the operation of the device under test. Thus, the sensor provided in this embodiment can detect the vibration, noise, temperature and the presence of harmful gases during the operation of the device under test through the vibration sensing unit 21, the noise sensing unit 22, the temperature sensing unit 23 and the gas sensing unit 24, and then collect the vibration data, noise data, temperature data and gas data of the device under test during operation.

[0038] In addition, the control component 3 is also located inside the mounting cavity, and the control component 3 is electrically connected to the vibration sensing unit 21, the noise sensing unit 22, the temperature sensing unit 23, and the gas sensing unit 24. At the same time, the control component 3 is also electrically connected to an external server, so that the control component 3 can receive the vibration data, noise data, temperature data, and gas data generated by the device under test during operation detected by the sensing component 2, and transmit the vibration data, noise data, temperature data, and gas data to the external server. This allows the staff to analyze the various data of the device under test during operation based on the vibration data, noise data, temperature data, and gas data received from the external server to determine whether the device under test is in a normal operating state.

[0039] Specifically, in this embodiment, the vibration sensing unit 21 uses a MEMS triaxial accelerometer, which can be embedded in the mounting surface of the device under test to collect vibration frequency and amplitude in real time; the noise sensing unit 22 has a built-in high-sensitivity microphone and noise reduction circuit, which can accurately capture the noise generated by the device under test during operation and filter out ambient noise; the temperature sensing unit 23 uses a patch digital temperature sensor, which can directly contact the surface of the device under test with the housing 1 to monitor the temperature rise; the gas sensing unit 24 is equipped with an electrochemical gas sensor, which can detect the concentration of volatile gases such as CO, NH3, and benzene.

[0040] In summary, by integrating the vibration sensing unit 21, noise sensing unit 22, temperature sensing unit 23, and gas sensing unit 24 into the housing 1, when it is necessary to detect the vibration, noise, temperature, and presence of harmful gases in the device under test, it is not necessary to install the corresponding sensors sequentially. Instead, the sensors in this embodiment can be installed on the outer surface of the device under test to detect the vibration, noise, temperature, and presence of harmful gases. This improves the installation efficiency of the sensors and avoids the wiring problems caused by installing multiple sensors simultaneously.

[0041] In one embodiment, such as Figure 1 As shown, it also includes several partitions 4, all of which are spaced apart in the mounting cavity to divide the mounting cavity into several receiving cavities. The vibration sensing unit 21, the noise sensing unit 22, the temperature sensing unit 23, the gas sensing unit 24 and the control component 3 are respectively disposed in one receiving cavity.

[0042] The aforementioned vibration sensor integrating noise, temperature, and harmful gas measurements uses several partitions 4 (in this embodiment, partition plates) set within the mounting cavity. These partitions 4 are spaced apart within the mounting cavity, dividing it into several accommodating chambers. This allows the vibration sensing unit 21, noise sensing unit 22, temperature sensing unit 23, gas sensing unit 24, and control component 3 to be respectively housed within a single accommodating chamber, preventing interference between them when collecting data from the device under test.

[0043] In one embodiment, such as Figure 1 As shown, the noise sensing unit 22, the gas sensing unit 24 and the control component 3 are respectively disposed in a receiving cavity, and the vibration sensing unit 21 and the temperature sensing unit 23 are disposed in the same receiving cavity.

[0044] The aforementioned vibration sensor integrating noise, temperature, and harmful gas measurements is designed by placing the noise sensing unit 22, the gas sensing unit 24, and the control component 3 in separate housings, and by placing the vibration sensing unit 21 and the temperature sensing unit 23 in the same housing. This is because the noise sensing unit 22 and the gas sensing unit 24 need to collect the sound and gas generated during the operation of the device under test. Therefore, in order to avoid interference from the sound and gas to other sensing units, the noise sensing unit 22 and the gas sensing unit 24 need to be placed in separate housings. The vibration sensing unit 21 and the temperature sensing unit 23 only need to contact the device to collect the vibration and temperature data generated during the operation of the device. Therefore, in order to effectively utilize the space of the mounting cavity inside the housing 1, the vibration sensing unit 21 and the temperature sensing unit 23 can be installed in the same housing.

[0045] In one embodiment, such as Figure 1 As shown, any of the partitions 4 has a connecting portion, which is adapted to connect two adjacent receiving cavities so that the control component 3 can be electrically connected to the vibration sensing unit 21, the noise sensing unit 22, the temperature sensing unit 23 and the gas sensing unit 24 respectively through the connecting portion.

[0047] In one embodiment, such as Figure 1 As shown, the control component 3 includes a processing unit 31 and a transmission unit 32 that are electrically connected. The processing unit 31 is electrically connected to the sensing component 2 to receive vibration data, noise data, temperature data and gas data of the device under test detected by the sensing component 2.

The transmission unit 32 is electrically connected to an external server, enabling it to transmit the vibration data, noise data, temperature data, and gas data received by the processing unit 31 to the external server.

[0049] Specifically, in this embodiment, the processing unit 31 is a multi-channel signal conditioning circuit. It uses an FPGA to realize the synchronous acquisition and preprocessing of four-channel data. At the same time, it has a built-in fault diagnosis algorithm that triggers graded early warnings by comparing vibration spectrum analysis, noise sound pressure level and gas concentration threshold. The transmission unit 32 supports LoRa / NB-IoT dual-mode communication, which can adapt to the transmission distance and power consumption requirements of different industrial scenarios. Moreover, it adopts data compression and packet transmission technology to ensure that multi-parameter data (vibration waveform, noise spectrum, temperature value, gas concentration) are uploaded to the external server with low latency.
