Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following description is made by way of specific embodiments with reference to the accompanying drawings.
Referring to fig. 1, it shows a flowchart of an implementation of a method for releasing fuze insurance provided by the embodiment of the present invention, which is detailed as follows:
In this embodiment, the method may be applied to a fuze fuse mechanism for ammunition, which includes a gas inlet control chamber, a pressure sensor, and a fuse release device. When ammunition is launched, gas pressure can promote the ammunition motion, and gas pressure can get into the gas and advance the control chamber and act on pressure sensor this moment, and for pressure sensor power supply, the data of reading the sensor collection and the gas pressure of conversion calculation this moment on the circuit power on work back.
The first fuse of the non-rotating ammunition fuze is usually the recoil fuse, and the method is used for relieving the second fuse in the non-rotating ammunition fuze and can also be used for relieving the fuze fuses of ammunition in other launching modes. When the non-rotating ammunition is launched, the gas pressure of the gunpowder can change within a certain period of time. The gas pressure sequence of the ammunition in the preset time period can reflect the firing condition of the ammunition.
In the embodiment, the ammunition of different types and firing modes has different pressure change rules under the normal firing condition, and needs to be preset in the fuze insurance release device according to the actual condition. After the gas pressure sequence of the ammunition is obtained, the fuse safety release device analyzes the change rule of the gas pressure sequence and compares the change rule with a preset pressure change rule. The gas pressure curve of gunpowder rises first and then falls for a certain time (generally several milliseconds) during launching, and different weapons and different ammunition fuze pressure curves have respective characteristics, and the pressure sensor and the fuze fuse release device accurately identify the launching environment and the launching time through the modes of 'multipoint acquisition, multipoint pressure value judgment and time window judgment' so as to be used for removing the accurate control of the fuze and identifying and removing the non-launching environment and the abnormal launching environment.
And 103, determining that the ammunition is in a normal launching state, and releasing fuse insurance of the ammunition.
In this embodiment, if the change rule of the gas pressure sequence conforms to the preset pressure change rule, it indicates that the ammunition is normally fired, and the fuse insurance can be released.
According to the embodiment of the invention, a gas pressure sequence of ammunition in a preset time period is obtained; judging whether the gas pressure change rule of the ammunition accords with a preset pressure change rule or not according to the gas pressure sequence; if yes, the ammunition is determined to be in a normal launching state, fuse insurance of the ammunition is relieved, the change rule of the gas pressure of the ammunition can be used as insurance of the ammunition fuse, the fuse insurance of the ammunition is relieved when conditions are met, and sensitivity of the ammunition action can be guaranteed when the ammunition is normally launched.
In some embodiments, step 102 may comprise:
if the initial pressure value of the gas pressure sequence is greater than the preset upper limit value, the tail pressure value is less than the preset lower limit value, the pressure duration is within the preset time interval, and the pressure value variation trend meets the preset variation trend, it is determined that the gas pressure variation rule of the ammunition accords with the preset pressure variation rule.
Illustratively, after ammunition is launched, gunpowder gas directly acts on a pressure sensor through a gas inlet control chamber, a fuse protector releasing device is electrified and initialized, then the pressure sensor is powered and used for collecting gas pressure, and pressure can be collected for multiple times and calculated by an algorithm to reduce errors. If the acquired pressure initial section is greater than the preset upper limit value, the acquired pressure tail section is less than the preset lower limit value, and the pressure duration and the change rule meet the requirements, the ammunition is determined to be in a normal launching state and meet the condition of fuse relief, the output control part in the circuit is used for fuse relief control, and the fuse is relieved within the specified time range.
The pressure of the ammunition normally tends to increase and then decrease. The fuse safety release device in the embodiment can accurately judge whether ammunition is in a normal launching state or not by judging the change rule of the gas pressure sequence through the pressure initial value, the pressure tail value, the pressure value change trend and the duration of the gas pressure sequence.
In some embodiments, the predetermined pressure variation law is a predetermined pressure variation curve.
Step 102 may include:
fitting a gas pressure change curve of the ammunition based on the gas pressure sequence;
and if the gas pressure change curve is consistent with the preset pressure change curve, determining that the gas pressure change rule of the ammunition accords with the preset pressure change rule.
In this embodiment, the fuse protector release device may obtain a gas pressure change curve at the time of firing the ammunition by a curve fitting algorithm. Fig. 2 is a schematic diagram of a normal ammunition pressure change curve. If the gas pressure change curve is consistent with the preset pressure change curve, the gas pressure change rule during ammunition launching is consistent with the gas pressure change rule of the ammunition under the normal condition. At this point the fuse can be released.
In some embodiments, the arming of the ammunition in step 103 may include:
the fuse of the ammunition is released within a specified time range.
In this embodiment, the gas pressure sequence may also be used to determine the firing timing of the ammunition. The fuse safety release device sends a safety release signal after determining that the ammunition is in a normal launching state, and the safety release signal can have a certain time delay so as to control the fuse to detonate the ammunition at a required time.
Referring to fig. 3, which is a flowchart illustrating an implementation of a method for releasing fuze insurance according to another embodiment of the present invention, the method includes:
In this embodiment, the gas pressure sequence may represent a particular firing state of the ammunition. If only a part of the gas pressure sequence has large values, the false triggering caused by the falling of ammunition is possible. Ammunition may also be in an abnormal firing condition. Because the gas pressure of the ammunition under the abnormal launching state has various change rules, whether the ammunition is in the abnormal launching state can be judged through an elimination method. After the ammunition is determined to be abnormally fired, the circuit in the fuze safety mechanism should send a discharge command to release all the electric energy in the fuze safety mechanism so that the ammunition can not be detonated any more, and the safety of the ammunition is ensured.
The method provided by the embodiment of the invention comprises the following steps: acquiring a gas pressure sequence of ammunition in a preset time period; judging whether the gas pressure change rule of the ammunition accords with a preset pressure change rule or not according to the gas pressure sequence; if yes, determining that the ammunition is in a normal launching state, and releasing fuse insurance of the ammunition. The invention takes the change rule of the gas pressure of the ammunition as the insurance of the ammunition fuse, removes the fuse insurance of the ammunition when the condition is met, and can ensure the sensitivity of the ammunition action when the ammunition is normally launched.
The embodiment of the invention has the beneficial effects that:
when ammunition is fired, gas pressure which is greatly higher than atmospheric pressure is generated, and the accurate measurement of the pressure can be used for fuse insurance and fuse relief. The gas pressure safety device can solve the problems of complex structure, low sensitivity, low universality, low intelligent degree and limited performance of the original gas pressure safety device. The embodiment of the invention adopts the circuit to control the acquisition part, and has the advantages of accurate control, quick response and high intelligent degree; the acquisition part uses a high-precision low-delay sensor, has the advantages of small error, high reliability and the like, can effectively solve the problems of quantitative detection of gas pressure, intelligent processing of detection data, relief of insurance accurate control and the like, and improves the application range of a gas pressure environment in an ammunition fuse so as to further improve the technical level of the ammunition fuse.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
