[0033] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application.

[0034] The intelligent verification device, the mine gas sensor testing device and method in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0035] Figure 1 The structural schematic diagram of an intelligent verification device provided in the first embodiment of the present application.

[0036] As Figure 1 shown, the intelligent verification device 1 includes:

[0037] A cabinet 11;

[0038] A plurality of gas sensors 12 located in the cabinet and a transmission mechanism 13 for driving all the gas sensors to move synchronously along a preset trajectory; any gas sensor is located in an open cavity; the gas sensor is used in pair with the cavity; and

[0039] An inflation calibration test assembly 14; when any gas sensor moves to a specific position along with the transmission mechanism, the inflation calibration test assembly located in the cabinet automatically extends to be separately docked with the gas sensor in the cavity to fill in the detection gas, and completes the automatic calibration test of the detection gas.

[0040] It can be understood that the cabinet 11 of the intelligent verification device can be divided into multiple layers, and a plurality of gas sensors 12, a transmission mechanism 13 for driving all the gas sensors to move synchronously along a preset trajectory, and an inflation calibration test assembly 14 are respectively installed in each layer to improve the efficiency of detecting gas sensors.

[0041] The intelligent calibration device of the embodiment of the present application includes a cabinet body; a plurality of gas sensors located in the cabinet body and a transmission mechanism for driving all the gas sensors to move synchronously along a preset trajectory; any gas sensor is located in an open cavity; the gas sensor is used in pair with the cavity; and an inflation calibration test component; when any gas sensor moves to a specific position along with the transmission mechanism, the inflation calibration test component located in the cabinet body automatically extends to be separately docked with the gas sensor in the cavity to fill in the detection gas, and the automatic calibration test of the detection gas is completed. Thus, the technical problems of poor durability, high failure rate and low working efficiency of the existing intelligent testing device can be solved, the real and sustainable intelligent improvement of the sensor testing level is realized, at the same time, the short board in the field of detection of mine gas sensors is improved, and the full-process unattended testing of gas sensors is realized.

[0042] Further, in the embodiment of the present application, the preset trajectory is an elliptical ring trajectory.

[0043] Further, in the embodiment of the present application, the transmission mechanism includes a transmission track, and all the cavities are fixedly arranged on the outer peripheral surface of the transmission track at equal intervals.

[0044] In the embodiment of the present application, the transmission track drives the gas sensors in the cavity to slide along the preset elliptical ring trajectory. When any gas sensor moves to a specific position along with the transmission mechanism, the sliding stops, and the inflation calibration test component automatically extends to be separately docked with the gas sensor in the cavity to fill in the detection gas, and the automatic calibration test is carried out. After the automatic calibration test of the gas sensor is completed, the transmission track drives the gas sensors in the cavity to continue to slide along the preset elliptical ring trajectory until the next gas sensor moves to a specific position along with the transmission mechanism for the automatic calibration test.

[0045] In the embodiment of the present application, the transmission track can supply power to the gas sensor so that the gas sensor can carry out the automatic calibration test. Among them, the elliptical ring transmission track is divided into multiple sliding loop tracks to supply power to multiple gas sensors respectively. It can be understood that except for the sliding loop track part for supplying power to the gas sensor in the transmission track, the rest is composed of insulating parts.

[0046] Exemplarily, the gas sensor can be driven to rotate in a track type and be electrified through the transmission track. As Figure 2 shown, the gas sensors are all independently suspended in an open cavity, all the cavities are fixedly arranged on the outer peripheral surface of the transmission track at equal intervals, the first partition board and the second partition board of the cavity fix and clamp the gas sensor. Among them, the elliptical ring shaded part is an "electric slip ring", which drives the Figure 2 gas sensors independently fixed and hung at the slant part in the figure to rotate in a track type according to the arrow direction, and each sensor automatically stops rotating when it rotates to the middle position.

[0047] The slip ring power-taking crawler rotation technology of the present application can better and more persistently and stably achieve the intelligent testing of the device hardware, without the need for the inflation calibration test component to stretch and slide significantly during the test, avoiding damage to the gas circuit and accelerating the aging of the airtightness.

[0048] Further, in the embodiment of the present application, the cavity includes a first partition on one side of the gas sensor and a second partition on the opposite side of the first partition; the gas sensor is independently suspended in the cavity, and its gas inlet faces the inflation calibration test component.

[0049] In the embodiment of the present application, the gas sensor is independently suspended in the cavity, and its gas inlet faces the inflation calibration test component. The gas sensor is fixed and locked by the first partition and the second partition of the cavity, so that the inflation calibration test component can automatically extend and dock with the gas sensor separately to fill the detection gas, and perform the automatic calibration test of the detection gas.

[0050] Further, in the embodiment of the present application, the inflation calibration test component includes a remote control calibration rod, a window image collector, an inflation chuck, an electric control telescopic rod, a fixed rod, and an infrared photometric button; the fixed rod is arranged in the cabinet; both ends of the electric control telescopic rod are respectively connected to the fixed rod and the inflation chuck, and the inflation chuck is matched with the gas inlet of the gas sensor; the window image collector is used to collect the concentration of the detection gas detected by the gas sensor; the infrared photometric button is connected to the electric control telescopic rod to automatically open the matching resistor of the gas sensor and effectively determine the brightness of the resistor light source; the remote control calibration rod is used to perform the automatic calibration test of the detection gas on the gas sensor.

[0051] In the embodiment of the present application, when the gas sensor moves to a specific position and stops rotating, the inflation rod of the inflation calibration test component will automatically extend and dock with the gas chamber of the gas sensor that has stopped rotating to start inflation calibration, and perform the test items one by one.

[0052] Such as Figure 3As shown, the inflation rod of the inflation calibration test component will automatically extend and dock into the gas sensor chamber that has stopped rotating to start inflation calibration, and the test items will be carried out one by one. Among them, the fixed rod of the inflation rod of the inflation calibration test component is connected to the pipeline for transporting and detecting gas under the transmission track. After the electric control telescopic rod automatically extends and docks into the gas sensor chamber through the six-degree-of-freedom inflation chuck, the detection gas is transported to the gas sensor. The window image collector in front of the digital display window of the gas sensor to be measured collects the concentration of the detection gas detected by the gas sensor, so as to obtain the change in the detection concentration of the gas sensor and determine whether the gas sensor is qualified. The infrared photometric button connected to the electric control telescopic rod is used to automatically turn on the matching resistor of the gas sensor and effectively determine the brightness of the resistor light source after the inflation rod automatically extends and docks into the gas sensor chamber, so as to determine whether the gas sensor is qualified; the remote control calibration rod is used to send a remote control detection signal to the gas sensor to be measured to perform an automatic calibration test of the detection gas on the gas sensor.

[0053] As Figure 4 shown, the inflation calibration test component includes a remote control calibration rod 1, a window image collector 2, a six-degree-of-freedom inflation chuck 3, an electric control telescopic rod 4, a fixed rod 5 and an infrared photometric telescopic button 6. Among them, the remote control calibration rod 1 is located in front of the gas sensor to be measured and is used to perform an automatic calibration test of the detection gas on the gas sensor to be measured; the window image collector 2 is located in front of the digital display window of the gas sensor to be measured and is used to collect the concentration of the detection gas detected by the gas sensor to be measured; both ends of the electric control telescopic rod 4 are respectively connected to the fixed rod 5 and the inflation chuck 3, and the inflation chuck 3 is matched with the gas inlet of the gas sensor to be measured; the infrared photometric button 6 is connected to the electric control telescopic rod 5 and is used to automatically turn on the matching resistor of the gas sensor to be measured and effectively determine the brightness of the resistor light source.

[0055] Further, in the embodiment of the present application, the inflation chuck has a multi-degree-of-freedom robotic arm structure, and a buffer docking inclined surface is provided on the inner wall of the side facing the gas sensor.

[0056] The inner wall of the inflation docking lifting interface in the embodiment of the present application is designed in a connection mode with inclined surface buffering. Through the design of the six-degree-of-freedom robotic arm ROS host technology, the inflation docking lifting interface is easy to embed and tightly fit the sensor chamber, solving the fitting obstacle caused by errors during the docking action, reducing the risk of component damage, and ensuring the durability and stability of the automatic inflation component.

[0057] Figure 5 It is a schematic structural diagram of a mine gas sensor test device provided by the second embodiment of the present application.

[0058] As shown Figure 5 in the figure, the mine gas sensor testing device includes:

[0061] It can be understood that the performance stability device of the embodiment of the present application can set a plurality of sealed boxes in one cabinet to separately or simultaneously perform inflation tests on the gas sensors in the sealed boxes.

[0062] It can be understood that the sealed box can be divided into multiple layers, and a plurality of gas sensors and inflation calibration test components corresponding to the gas sensors one by one are installed in each layer. The inflation calibration test components are arranged in the box to connect and fill the detection gas into the gas sensor separately or simultaneously to complete the automatic calibration test of the detection gas. Among them, the inflation calibration test components in each layer can be connected to the same detection gas delivery pipeline.

[0063] The present application adopts the method of centralized gas supply in the laboratory. In the test device, the gas cylinders and the sensor test cavities are placed in a partitioned manner, and the gas in the explosive and toxic gas cylinders is transported to the sensor test cavities through the gas supply pipeline.

[0064] The mine gas sensor testing device of the embodiment of the present application includes an intelligent verification device; and a performance stability device, which is used to perform stability detection on the gas sensor and includes at least one sealed box; a plurality of gas sensors and a plurality of inflation calibration test components are accommodated in the box, and the inflation calibration test components are arranged in the box to connect and fill the detection gas into the gas sensor separately or simultaneously to complete the automatic calibration test of the detection gas. Thus, the technical problems of poor durability, high failure rate, and low working efficiency of the existing intelligent testing device can be solved, and the truly sustainable intelligent improvement of the sensor testing level is realized.

[0065] The present application provides a two - set mine gas sensor testing device. Based on the original coal mine safety monitoring system, a six - degree - of - freedom robotic arm, ROS host technology, and a monitoring waste gas system are implanted; a unique design that combines slip - ring power - taking technology and an inflation test unit for mutual cooperation in testing is adopted, and the test data information is intelligently collected, analyzed, automatically archived, and printed.

[0066] Figure 6 Flow chart of a method for testing a mine gas sensor provided in Embodiment 3 of the present application;

[0067] As Figure 6 shown, the method for testing the mine gas sensor includes the following steps:

[0068] Step 101: Install the gas sensor into the intelligent calibration device, and drive the gas sensor to move synchronously along a preset trajectory through the transmission mechanism of the intelligent calibration device;

[0069] Step 102: When the gas sensor moves to a specific position along with the transmission mechanism, connect the inflation calibration test component to the gas sensor to fill in the detection gas, and perform an automatic calibration test on the detection gas;

[0070] Step 103: Collect the test data of the gas sensor through the window image collector of the inflation calibration test component, and judge whether the gas sensor meets the preset requirements according to the test data;

[0071] Step 104: If the gas sensor meets the preset requirements, save the test data of the gas sensor and determine that the gas sensor is qualified.

[0072] In the method for testing the mine gas sensor according to the embodiment of the present application, by installing the gas sensor into the intelligent calibration device and driving the gas sensor to move synchronously along a preset trajectory through the transmission mechanism of the intelligent calibration device; when the gas sensor moves to a specific position along with the transmission mechanism, connect the inflation calibration test component to the gas sensor to fill in the detection gas, and perform an automatic calibration test on the detection gas; collect the test data of the gas sensor through the window image collector of the inflation calibration test component, and judge whether the gas sensor meets the preset requirements according to the test data; if the gas sensor meets the preset requirements, save the test data of the gas sensor and determine that the gas sensor is qualified. Thus, the technical problems of poor durability, high failure rate and low working efficiency of the existing intelligent testing device can be solved, and the real and sustainable intelligent improvement of the sensor testing level is realized.

[0073] In the embodiment of the present application, if it is determined that the gas sensor is unqualified during the test, the power will be automatically cut off, and at the same time, the six-degree-of-freedom inflation chuck will be automatically retracted to disconnect the inflation.

[0074] Further, in the embodiment of the present application, after it is determined that the gas sensor is qualified, it further includes:

[0075] Install the gas sensor into the performance stable device, and connect the inflation calibration test component to the gas sensor to fill in the detection gas for an automatic calibration test on the detection gas within a preset time to complete the stability detection of the gas sensor.

[0076] Further, in the embodiments of the present application, after the inflation calibration test component is docked with the gas sensor to fill the detection gas, the following steps are further included:

[0077] Detect the concentration of the detection gas in the cabinet of the intelligent calibration device through a standard gas sensor;

[0079] Discharge the non-toxic and harmless gas to the atmosphere through the ventilation system.

[0080] Most of the gases used for gas sensor test calibration in the test device are toxic, harmful, flammable and explosive dangerous gases. The present application uses the photocatalytic oxidation technology of activated carbon fiber loaded with TiO2 to adsorb and treat the toxic and harmful gases in the intelligent test device, and uses light to decompose and remove toxic and harmful gases such as CH4, CO and SO2 into odorless and harmless products by the photocatalytic oxidation technology of activated carbon fiber, avoiding affecting the physical health of the test personnel, and can be discharged to the atmosphere without pollution through the ventilation system, providing guarantee for personal safety and the safe production of coal mines.

If the test data analysis is unqualified, automatically cut off the gas and power supply, and manually remove it and send it back to the factory for repair; if the test data analysis is qualified, determine that the gas sensor to be tested is qualified, archive the test data, and manually remove it.

[0083] The two sets of test devices of the present application are designed with a slip ring power taking technology and an inflation test unit to cooperate with each other for intelligent test and automatic acquisition and analysis of data information, with strong durability.
