[0022] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] like Figure 1-7 As shown, a muzzle multi-parameter sensor system includes: a fastener, which is used to be installed and fixed on the outside of the muzzle of a gun barrel, the fastener includes an upper hoop 1 and a lower hoop 2, the connection between the upper hoop 1 and the lower hoop 2 is connected by a clamping screw 3, the bottom of the lower hoop 2 has a sensor mounting seat 4, the sensor mounting seat 4 is penetrated by a connecting screw 7, the length direction of the connecting screw 7 is parallel to the axis of the fastener, the bottom of the sensor mounting seat 4 has a collection box 5, the top of the collection box 5 has two parallel ear plates 6, the two ends of the connecting screw 7 are respectively penetrated on the two ear plates 6, the bottom surface of the lower hoop 2 is installed with a temperature sensor 11, the temperature sensor 11 is embedded in the lower hoop 2, and the temperature sensor 11 is electrically connected to the collection box 5 through a data line 8. It should be noted that the system is generally composed of two parts, the upper part is an integrated sensor system, whose main function is to hold the muzzle, sense the acceleration and temperature signals of the muzzle, and transmit them to the acquisition system through cables; the lower part is the acquisition system, which mainly supplies power to the sensor, digitizes the signal, and performs related edge processing.

[0024] In a preferred embodiment of the utility model, anti-vibration springs 9 and anti-vibration gaskets 10 are respectively installed between the two ends of the connecting screw 7 on the outside of the sensor mounting base 4 and the ear plate 6, so that the fastener has a certain buffer structure relative to the collection box 5, thereby preventing impact.

[0025] In a preferred embodiment of the utility model, the inner surfaces of the upper hoop 1 and the lower hoop 2 are provided with anti-loosening friction layers to increase their preload force, increase high temperature resistance inside the ring, and have a higher friction coefficient with the barrel material, ensuring sufficient clamping force under the clamping action of the fastener.

[0026] In the preferred embodiment of the utility model, a three-axis impact sensor 12 is installed in the sensor mounting seat 4, and the three-axis impact sensor 12 is electrically connected to the acquisition box 5 through the data line 8. The three-axis impact sensor 12 is a three-directional impact acceleration sensor; for dynamic acceleration measurement, the best solution at present is an acceleration sensor developed using the piezoelectric effect. This type of sensor is characterized by its resistance to impact and high temperature, and can be applied to the complex environment of the muzzle, wherein the X direction is along the barrel direction, the Y direction is parallel to the ground and perpendicular to the barrel direction, and the Z direction is perpendicular to the ground direction.

[0027] Piezoelectric accelerometers work based on the piezoelectric effect of piezoelectric crystals. When a piezoelectric material is deformed in a certain direction by an external force, the electric dipole moment in the material will shorten due to compression. At this time, the piezoelectric material will generate equal positive and negative charges on the opposite surfaces of the material to resist this change and maintain its original shape. When the external force is removed, it returns to a non-charged state. This phenomenon of electric polarization due to deformation is called the "positive piezoelectric effect". Figure 6 As shown. The positive piezoelectric effect is essentially the process of converting mechanical energy into electrical energy. If the applied pressure is a high-frequency vibration, a high-frequency current signal will be generated. Piezoelectric accelerometers are made using this phenomenon.

[0028] The main design considerations of piezoelectric accelerometers are two aspects: one is the design of piezoelectric materials, and the other is the structural design of the sensor.

[0029] Based on the empirical data from its tests, the following requirements are put forward for the technical indicators of the sensor:

[0030] Sensitivity: 1-100mV / g

[0031] Range: 50-5000g

[0032] Frequency response range: 1-10kHz

[0033] Direction: X, Y, Z three-way, can also be one-way, two-way or three-way

[0034] Output mode: IEPE, charge output or voltage output multiple interfaces

[0035] Operating temperature: -50℃~150℃.

[0036] In the preferred embodiment of the utility model, the acquisition box 5 includes a high-strength shell, and a collection controller is installed in the high-strength shell. The collection controller is powered by a battery. The collection adopts a collection circuit with an SMT32 series chip as the core, such as Figure 5As shown, it includes digital acquisition and analog acquisition, as well as integrated design solutions for ADC and communication interface processing. Digital acquisition is mainly aimed at two digital sensors, namely accelerometers and gyroscopes, and analog acquisition is mainly aimed at 4-way high-speed acquisition, mainly collecting acceleration in three directions and one temperature. The setting of FLASH is to ensure the storage and reading of the collected data and realize the storage function. At the same time, the processing of the power module is completed to realize the management of the battery and the demand for device power supply.

[0037] In a preferred embodiment of the utility model, the temperature sensor 11 is in a cylindrical structure, the active part of the temperature sensor 11 is on the top surface, and a heat insulation protection layer and a vibration isolation protection layer are sequentially arranged on the outer side of the temperature sensor 11 from the inside to the outside.

[0038] In the preferred embodiment of the utility model, the upper hoop 1 and the lower hoop 2 are made of aluminum alloy. Since the rigidity of the muzzle has certain requirements, the basic material is selected from aluminum alloy materials with lower density and better dynamic response. In order to improve its impact bearing capacity, 7 series high-strength aluminum alloy is selected.

[0039] In a preferred embodiment of the utility model, the number of the clamping screws 3 at the connection between the upper hoop 1 and the lower hoop 2 is at least 6, and anti-loosening washers, double nuts, fuse interlocking and other solutions are designed to ensure that the pre-tightening force is not loosened.
