Technical Field

[0001] The invention belongs to the technical field of energetic materials, relates to performance evaluation of energetic materials, and specifically relates to a wireless gas detection device and a detection method suitable for explosion fields. Background Art

[0002] The development of highly effective destructive ammunition is achieved through the improvement of the energy utilization rate of explosives and the application of new high-energy explosive formulas. The improvement of energy utilization rate is closely dependent on the study of the detonation mechanism and energy release law of ammunition. By tracking and analyzing the detonation products, the detonation reaction equation of highly effective destructive ammunition can be obtained to reverse the reaction process. In this way, there is an urgent need for a test system that can dynamically reflect the solid and gas phase products of detonation at multiple points under different explosion environments, which not only meets the requirements of on-site testing but also provides basic data for mechanism research. The current testing method is mainly completed by static explosion tests using a simple gas tester to test the single-point oxygen content. There is no unified damage assessment standard and test method, which makes the warhead structure design and charge formula adjustment lack of pertinence; Summary of the invention In view of the shortcomings of the prior art, the purpose of the present invention is to provide a wireless gas detection device and detection method suitable for explosion fields, so as to solve the technical problem that the detection success rate and efficiency in the prior art need to be further improved.

[0003] In order to solve the above technical problems, the present invention adopts the following technical solutions to achieve the above problems: A wireless gas detection device suitable for explosion fields comprises a gas sensor connected to a wireless data transmitter. The base end of the gas sensor and the wireless data transmitter are both installed in an explosion-proof housing, and the detection end of the gas sensor extends out of the explosion-proof housing.

[0004] A layer of impact-resistant lining is arranged on the wall of the explosion-proof housing.

[0005] The gas sensor is also connected with a data storage device and a battery.

[0006] The battery is also connected to the wireless data transmitter and the data storage device for power supply.

[0007] The gas sensor is an oxygen content sensor.

[0008] The present invention also protects a wireless gas detection method applicable to an explosion field, the method adopting the wireless gas detection device applicable to an explosion field as described above.

[0009] Measuring points 1 and 2 are arranged in the same radial direction in the west of the explosion center; measuring points 3 and 4 are arranged in the same radial direction in the south of the explosion center; the gas sensors are arranged on the measuring points 1, 2, 3 and 4 respectively.

[0010] The measuring point 1 is 5m away from the explosion center, the measuring point 2 is 8m away from the explosion center, the measuring point 3 is 11m away from the explosion center, and the measuring point 4 is 14m away from the explosion center.

[0025] Specific embodiments of the present invention are given below. It should be noted that the present invention is not limited to the following specific embodiments, and all equivalent changes made on the basis of the technical solution of this application fall within the protection scope of the present invention.

[0026] Embodiment 1: This embodiment provides a wireless gas detection device suitable for explosion fields, such as Figure 1 As shown, the device includes a gas sensor 1, to which a wireless data transmitter 2 is connected. The base end of the gas sensor 1 and the wireless data transmitter 2 are both installed in an explosion-proof housing 3, and the detection end of the gas sensor 1 extends out of the explosion-proof housing 3.

[0027] like Figure 1 As shown, a layer of impact-resistant lining 4 is arranged on the wall of the explosion-proof housing 3 .

[0028] like Figure 1 As shown, a data storage device 5 and a battery 6 are also connected to the gas sensor 1 .

[0029] like Figure 1 As shown, the battery 6 is also connected to the wireless data transmitter 2 and the data storage 5 for power supply.

[0030] As a preferred solution of this embodiment, the gas sensor 1 is an oxygen content sensor.

[0031] In this embodiment, when conducting an explosion field gas detection test, the wireless data sent by the wireless data transmitter 2 can be remotely received through a known control platform, and the data storage device 5 records the test data at the same time. The double data recording ensures that the data will not be lost during the test.

[0032] In this embodiment, the wireless data transmitter 2 and the data storage 5 are both known and commonly used wireless data transmitters and data storages.

[0033] In this embodiment, the explosion-proof shell 3 can prevent the physical damage of explosion fragments to the detection device, and the impact-resistant lining 4 can prevent the shock damage of the internal module of the detection device caused by the instantaneous impact generated at the moment of explosion.

[0034] In this embodiment, the battery 6 is used for power supply, and there is no need to lay power supply cables at the test site, thereby improving the test site layout efficiency.

[0035] Embodiment 2: This embodiment provides a wireless gas detection method applicable to an explosion field. The method adopts the wireless gas detection device applicable to an explosion field provided in Embodiment 1.

[0036] First, how to use the gas detection device: The test device can deploy multiple oxygen content sensors at different locations on site as required, and each oxygen content sensor converts the oxygen content at that location into a digital signal. The signal is transmitted wirelessly to a control platform at a safe distance.

[0037] Second, the test process: Test layout: Figure 2 As shown, measuring point 1 (5m from the explosion center) and measuring point 2 (8m from the explosion center) are arranged in the same radial direction in the west of the explosion center; measuring point 3 (11m from the explosion center) and measuring point 4 (14m from the explosion center) are arranged in the same radial direction in the south of the explosion center; the gas sensors 1 are arranged on the measuring points 1, 2, 3 and 4 respectively. The azimuth angle between the west and the south is 90°.

[0038] Field test data such as Figures 3 to 6 As shown, according to Figures 3 to 6 , we can get the test results shown in Table 1.

[0039] Table 1 Test data statistics

[0040] From Table 1, we can see that the initial oxygen concentration / %, the lowest oxygen concentration / %, and the oxygen consumption duration / s are the original test values. Among them, the explosion time can be clearly judged on the real-time test curve. Taking this as the starting point of time, the time when the sensor test data returns to the initial oxygen concentration in the air is the oxygen consumption duration. From this, the concentration-time integral area is calculated to characterize the oxygen consumption effect of the warhead.
