Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, techniques, etc., in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application 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 application with unnecessary detail.
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the following description will be made by way of specific embodiments with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of implementation of a fuse insurance releasing method provided by an embodiment of the present application is shown, and details are as follows:
step 101, acquiring a gas pressure sequence of ammunition in a preset time period.
In this embodiment, the method may be applied to a fuse safety mechanism for ammunition that includes a gas inlet control chamber, a pressure sensor, and a fuse arming device. When ammunition is launched, the gas pressure can promote the ammunition to move, and the gas pressure can enter the gas inlet control chamber to act on the pressure sensor at the moment, and after the circuit is electrified and works, the pressure sensor is powered, data acquired by the sensor are read, and the gas pressure at the moment is calculated through conversion.
The first pass of non-rotary ammunition fuse is typically a recoil fuse, and the method is used to disarm the second pass of non-rotary ammunition fuse, but may also be used to disarm fuses of other firing modes of ammunition. When non-rotary ammunition is launched, the gunpowder gas pressure can change within a certain period of time. The firing of ammunition can be reflected by the gas pressure sequence of ammunition within a preset time period.
Step 102, judging whether the gas pressure change rule of ammunition accords with a preset pressure change rule according to the gas pressure sequence; the preset pressure change rule represents the change rule of the gas pressure of the ammunition in a normal transmitting state. If yes, go to step 103.
In this embodiment, the pressure change rules of ammunition of different types and different firing modes under the normal firing condition are different, and the ammunition needs to be preset in a fuse safety releasing device according to actual conditions. After the gas pressure sequence of the ammunition is obtained, the fuze safety releasing device analyzes the change rule of the gas pressure sequence and compares the change rule with a preset pressure change rule. The pressure curve of the gunpowder gas is a pressure curve which rises and then falls for a certain time (generally a few milliseconds) during firing, and the pressure curves of different weapons and different ammunition fuses have respective characteristics, and a pressure sensor and a fuse safety releasing device accurately identify the firing environment and the firing opportunity by a mode of 'multipoint acquisition + multipoint pressure value judgment + time window judgment', so as to be used for releasing precise control of safety, non-firing environment and abnormal firing environment identification and elimination.
Step 103, determining that the ammunition is in a normal firing state, and releasing the fuse insurance of the ammunition.
In this embodiment, if the change rule of the gas pressure sequence accords with the preset pressure change rule, it is indicated that the ammunition is normally launched, and fuse insurance can be relieved.
According to the embodiment of the application, the fuel gas pressure sequence of ammunition in the preset time period is obtained; judging whether the gas pressure change rule of the ammunition accords with a preset pressure change rule according to the gas pressure sequence; if the conditions are met, the ammunition is determined to be in a normal firing state, fuse insurance of the ammunition is released, the change rule of the gas pressure of the ammunition can be used as the fuse insurance of the ammunition, and when the conditions are met, the fuse insurance of the ammunition is released, so that the sensitivity of the ammunition in action can be ensured when the ammunition is fired normally.
In some embodiments, step 102 may include:
if the initial pressure value of the fuel gas pressure sequence is larger than the preset upper limit value, the end pressure value is smaller than the preset lower limit value, the pressure duration is within the preset duration interval, and the pressure value change trend meets the preset change trend, the fuel gas pressure change rule of the ammunition is determined to be in accordance with the preset pressure change rule.
Illustratively, after ammunition is launched, the gunpowder gas directly acts on the pressure sensor through the gas inlet control chamber, the fuse safety relieving device is powered on and initialized, then the pressure sensor is powered and the gas pressure is acquired by the pressure sensor, and multiple times of pressure can be acquired and calculated by using an algorithm to reduce errors. If the collected pressure initial section is larger than the preset upper limit value, the collected pressure final section is smaller than the preset lower limit value, and the pressure duration time and the change rule meet the requirements, the ammunition is determined to be in a normal firing state and accords with the conditions for releasing the fuse, the output control part in the circuit is used for releasing the fuse, and the fuse is released within the specified time range.
Normally the pressure trend of ammunition is generally increasing and then decreasing. According to the fuse safety releasing device in the embodiment, the change rule of the gas pressure sequence is judged through the pressure initial value, the pressure end value, the pressure value change trend and the duration of the gas pressure sequence, so that whether ammunition is in a normal emission state can be accurately judged.
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;
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 releasing device may obtain a gas pressure change curve during ammunition firing through a curve fitting algorithm. Fig. 2 is a schematic representation of a normal ammunition pressure profile. If the gas pressure change curve is consistent with the preset pressure change curve, the gas pressure change rule when ammunition is launched is proved to be consistent with the gas pressure change rule of ammunition under normal conditions. At this point the fuse can be released.
In some embodiments, arming the ammunition in step 103 may include:
and releasing the fuse of the ammunition within a specified time range.
In this embodiment, the gas pressure sequence may also be used to determine the timing of the firing of the ammunition. The fuse arming device sends out an arming signal after determining that the ammunition is in a normal firing state, and a certain time delay exists in the arming signal so as to control the fuse to detonate the ammunition at required time.
Referring to fig. 3, a flowchart of a method for releasing fuse insurance according to another embodiment of the present application is shown, where the method includes:
in step 301, a gas pressure sequence of ammunition within a preset time period is acquired.
Step 302, judging whether the gas pressure change rule of the ammunition accords with a preset pressure change rule according to the gas pressure sequence; the preset pressure change rule represents the change rule of the gas pressure of the ammunition in a normal transmitting state. If yes, go to step 303, if no, go to step 304.
Step 303, determining that the ammunition is in a normal firing state, and releasing the fuse insurance of the ammunition.
Step 304, determining that the ammunition is in an abnormal firing state.
In this embodiment, the gas pressure sequence may embody a specific firing state of the ammunition. If only a portion of the gas pressure sequence has a large value, it is possible that the gas pressure sequence may be triggered by a drop of ammunition. Ammunition may also be in an abnormal firing condition. Because of various change rules of the gas pressure of the ammunition in the abnormal firing state, whether the ammunition is in the abnormal firing state or not can be judged by an elimination method. After the abnormal firing of the ammunition is determined, a circuit in the fuse safety mechanism should send a discharge instruction to release all the electric energy in the fuse 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 application 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 according to the gas pressure sequence; if yes, determining that the ammunition is in a normal firing state, and releasing the fuse insurance of the ammunition. The application takes the change rule of the fuel gas pressure of the ammunition as the fuse of the ammunition, releases the fuse of the ammunition when meeting the conditions, and can ensure the sensitivity of the ammunition when the ammunition is normally launched.
The beneficial effects of the embodiment of the application include:
during ammunition firing, a gas pressure which is greatly higher than the atmospheric pressure is generated, and the accurate measurement of the gas pressure can be used for fuze insurance and relief insurance. 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 application adopts a circuit control acquisition part, and has the advantages of accurate control, quick response and high intelligent degree; the acquisition part uses the 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, precise control of safety relief and the like, improves the application range of the gas pressure environment in the ammunition fuse, and further improves the technical level of the ammunition fuse.
