Description

Technical Field

[0001] The present invention relates to the technical field of data acquisition, and in particular to an intelligent sensing data acquisition device and a data acquisition system. Background Art

[0002] Sensor data acquisition refers to the process of sensing and measuring various information in the physical world through sensors and other devices, and converting them into processable forms such as electrical signals or digital signals so that computers or other data processing systems can store, analyze and use them. The following is a detailed introduction to it: Perception: Utilizing various sensors, such as temperature sensors, pressure sensors, and photoelectric sensors, to perceive specific information in the physical world, such as temperature, pressure, and light intensity. These sensors can respond to corresponding physical quantities and convert them into electrical signals or other easily processable signal forms.

[0003] Measurement: Accurately measure a perceived physical quantity to determine its specific value or range. Sensors typically have a certain level of measurement accuracy and resolution to ensure that the collected data accurately reflects the physical phenomenon being measured.

[0004] Conversion: Converting the analog signal output by the sensor into a digital signal so that it can be processed and stored by computers or other digital devices. This process is usually completed by an analog-to-digital converter (ADC), which discretizes the continuous analog signal into a digital quantity, allowing the data to be transmitted, stored, and analyzed in digital form.

[0005] For example, the authorization announcement number is CN 220232560 U, and the patent name is a utility model patent for a data acquisition device and monitoring system based on passive wireless sensors. The patent includes a passive wireless sensor component, an antenna module, and a data reader. The passive wireless sensor component is configured to respond to receiving radio waves from the antenna module and collect data on the physical quantity of the monitored equipment after power is turned on. The antenna module is set up in conjunction with the passive wireless sensor component and is configured to send radio waves to the passive wireless sensor component and receive collected data from the passive wireless sensor component. The data reader is signal-connected to the antenna module and is configured to send radio excitation signals to the antenna module and read the collected data transmitted back by the passive wireless sensor component in the antenna module. The passive wireless sensor component is easy to install, suitable for multi-point distribution, and easy to arrange and implement. Compared with existing multi-point sensor systems, the passive wireless sensor component is low-cost and suitable for application in large-scale products.

[0027] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0028] Example 1: like Figures 1 to 6 As shown, an embodiment of the present invention provides an intelligent sensor data acquisition device, comprising: Specifically, the mounting base 1 is installed on the plane to be installed.

[0029] The collection box 2 is detachably mounted on the mounting base 1 . The collection box 2 is provided with a plurality of mounting windows 3 , and the mounting windows 3 are used for mounting sensors 16 .

[0030] The sensor base 4 is arranged inside the collection box 2, and the sensor base 4 is arranged corresponding to the installation window 3. The sensor base 4 is used to electrically connect the sensor 16.

[0031] The fastener 5 is detachably mounted on the collection box 2 and is used to position and fix the sensor 16 .

[0032] In this embodiment, the type of sensor 16 is determined based on the on-site detection requirements. Once the type of sensor 16 is determined, the sensor 16 is inserted into the mounting window 3, with the base of the sensor 16 contacting the sensor base 4, completing the electrical connection and installation of the sensor 16. Subsequently, the installed sensor 16 is secured using fasteners 5 to prevent loosening during operation, ensuring that the sensor 16 remains stable and in working order, thereby ensuring the smooth operation of the intelligent sensing data acquisition process. Finally, the acquisition box 2 is attached to the mounting base 1 by suction, completing the installation of the entire intelligent sensing data acquisition device.

[0033] In one embodiment, the mounting base 1 is provided with mounting holes 20 on its edge. A positioning groove 21 is provided on the side of the mounting base 1 facing the collection box 2. The collection box 2 is magnetically secured within the positioning groove 21. The mounting base 1 is bolted to the surface to be mounted. Once the mounting base 1 is secured, the collection box 2 can be attached to the mounting base 1 by suction. Furthermore, the positioning groove 21 limits the position of the collection box 2, effectively preventing it from slipping off the mounting base 1.

[0034] It should be noted that the mounting window 3 and sensor base 4 are compatible with the MQ series gas sensors. The MQ series gas sensors, manufactured by manufacturers such as Weisheng Technology in China, are used to detect various gases and are widely used in various fields. Most MQ series gas sensors utilize the metal oxide semiconductor (MOS) principle. Their sensitive elements are typically made of semiconductor materials made of metal oxides (such as tin dioxide). When the sensor is exposed to an environment containing the target gas, target gas molecules adsorb onto the sensor surface and interact with the semiconductor material.

[0035] For reducing gases (such as hydrogen and carbon monoxide), gas molecules on the sensor surface lose electrons and become oxidized, while the semiconductor material in the sensor gains electrons, causing its resistance to decrease. For oxidizing gases (such as oxygen and nitrogen dioxide), the semiconductor material loses electrons, increasing its resistance. By measuring this change in sensor resistance, the presence and concentration of the target gas can be detected.

[0036] In this embodiment, if other types of sensors are used, the installation window and the sensor base 4 can be set according to the sensor pins.

[0037] Furthermore, the sensor base 4 includes: The connecting seat 6 is fixedly arranged inside the collection box 2.

[0038] The female socket 7 is fixedly arranged on the connecting socket 6, and the female socket 7 has a connecting cavity inside that matches the pin of the sensor 16.

[0039] An elastic positioning sleeve 8 is fixedly mounted on the connecting seat 6 , and the elastic positioning sleeve 8 is sleeved on the outside of the female seat 7 , with the inner wall of the elastic positioning sleeve 8 in close contact with the outer wall of the female seat 7 .

[0040] In this embodiment, when installing the sensor 16, the root of the sensor 16 is inserted into the female base 7. The electrical connection between the sensor 16 and the female base 7 is achieved through the contact between the root of the sensor 16 and the female base 7. At the same time, the female base 7 is squeezed and expanded after the root of the sensor 16 is inserted. At this time, the elastic positioning sleeve 8 elastically positions the female base 7, ensuring a firm contact between the female base 7 and the root of the sensor 16, thereby ensuring the stable transmission of the detection signal of the sensor 16.

[0041] In a specific embodiment, the female seat 7 includes: a positioning bar 9, a plurality of positioning bars 9 are vertically arranged, and the plurality of positioning bars 9 are circumferentially distributed on the connecting seat 6; a contact protrusion 10, the contact protrusion 10 is fixedly arranged on the inner side surface of the positioning bar 9, and an insertion gap is reserved in the center surrounded by the contact protrusion 10.

[0042] When the root of the sensor 16 is inserted from the middle of the positioning strip 9, the root of the sensor 16 is in close contact with the contact protrusion 10, thus achieving electrical connection between the root of the sensor 16, the contact protrusion 10, and the positioning strip 9. When the root of the sensor 16 is inserted to the bottom of the positioning strip 9, the pressure of the root of the sensor 16 on the contact protrusion 10 causes the positioning strip 9 to be in an expanded state. At this time, the elastic positioning sleeve 8 provides elastic force to the outer wall of the positioning strip 9, so that the contact protrusion 10 can be firmly in contact with the root of the sensor 16. In addition, after the sensor 16 is pulled out, the elastic positioning sleeve 8 can drive the positioning strip 9 to close, ensuring a subsequent firm connection between the sensor 16 and the sensor base 4.

[0043] The vertical cross-section of the contact protrusion 10 is trapezoidal. The trapezoidal slope guides the insertion of the sensor 16 into the positioning bar 9, facilitating installation. Furthermore, when the sensor 16 is fully inserted, the base of the sensor 16 maintains a large contact area with the bottom surface of the contact protrusion 10, ensuring a stable electrical connection between the two.

[0044] Furthermore, the fastener 5 includes: Buckle 11, two buckles 11 are provided, and the two buckles 11 are fixedly provided on the outer side wall of the collection box 2.

[0045] The positioning connecting belt 12 has two ends detachably connected to the buckle 11 .

[0046] The fixed mesh cover 13 is fixedly arranged on the positioning connecting belt 12 , the fixed mesh cover 13 matches the sensor 16 , and the fixed mesh cover 13 is sleeved on the outside of the sensor 16 .

[0047] In this embodiment, both ends of the positioning connecting belt 12 are provided with slots 14 that match the buckle 11 , and when the buckle 11 is engaged with the slots 14 , the positioning connecting belt 12 is in contact with the surface of the collection box 2 .

[0048] After the sensor 16 is inserted into the sensor base 4 and the electrical connection is completed, the sensor 16 is only fixed and positioned between the root and the sensor base 4, while the head of the sensor 16 is not firmly fixed, which can easily cause the sensor 16 to loosen, thereby affecting the transmission of electrical signals.

[0049] In the present embodiment, after the sensor 16 is installed on the sensor base 4, the fixed mesh cover 13 is placed on the outside of the sensor 16, and the two ends of the positioning connecting belt 12 connected to the fixed mesh cover 13 are detachably connected to the buckle 11, which can firmly position the sensor 16 and avoid loosening of the transmission, thereby ensuring a firm connection between the sensor 16 and the sensor base 4, thereby ensuring the stable operation of the sensor 16.

[0050] In one embodiment, the entrance of the fixed mesh cover 13 is provided with a chamfered structure, so that the fixed mesh cover 13 is in close contact with the outer wall of the sensor 16. The chamfered structure at the entrance of the fixed mesh cover 13 facilitates the insertion of the fixed mesh cover 13 onto the sensor 16. In addition, the close contact between the fixed mesh cover 13 and the outer wall of the sensor 16 can reduce the shaking of the sensor 16, thereby ensuring a secure connection between the sensor 16 and the sensor base 4.

[0051] Example 2: On the other hand, Figure 7 As shown, the present invention also discloses an intelligent sensor data acquisition system, which adopts the above-mentioned intelligent sensor data acquisition device and includes: The controller 15 is used to receive the sensor data and analyze and process the sensor data.

[0052] The sensor 16 is connected to the controller 15 through the sensor base 4 , and is used to collect and detect parameter information of the area to be inspected.

[0053] The communication module 17 is connected to the controller 15 and is used to transmit the sensor data analyzed and processed by the controller 15 to a remote terminal and receive control instructions from the remote terminal.

[0054] The power supply 18 is electrically connected to the controller 15 , the sensor 16 , and the data transmission module. The power supply 18 is used to provide working power.

[0055] In this embodiment, the controller 15 is disposed in the collection box 2 , and an input end of the controller 15 is connected to the sensor base 4 . After the sensor 16 is inserted into the sensor base 4 , the connection between the sensor 16 and the controller 15 can be achieved.

[0056] When the intelligent sensor data acquisition system is operating, power supply 18 supplies power to controller 15, sensor 16, and communication module 17. Sensor 16 collects real-time sensor data from the field and transmits it to controller 15. Controller 15 processes and analyzes the sensor data and then transmits it to a remote terminal via communication module 17. The remote terminal then receives real-time information about the sensor data collected by sensor 16. Simultaneously, the remote terminal can send control commands to controller 15, such as the frequency of sensor data collection and alarms for exceeding thresholds. This enables intelligent remote monitoring of sensor data.

[0057] In a specific embodiment, the intelligent sensor data acquisition system also includes a verification reset module 19, which is electrically connected to the controller 15. The verification reset module 19 is used to monitor the working status of the sensor 16 and send a reset instruction to the controller 15 when the working status of the sensor 16 is abnormal. When sensor 16 detects data that remains constant or shows no signal input, verification and reset module 19 detects an abnormal state and issues a reset command to controller 15. After the reset, sensor 16 resumes normal operation, eliminating the need for verification and reset module 19. If the aforementioned error persists after the reset, verification and reset module 19 transmits an abnormal operation signal to a remote terminal via controller 15 and communication module 17.

[0058] The reset verification module 19 can set a threshold for the reset instruction through the controller 15. When the number of resets reaches the threshold, an abnormal operation signal is sent to the remote terminal to remind the operator to go to the site for processing.

[0059] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
