[0023] A detection device for longitudinal folding wing deployment time and angle is mainly used for measuring, displaying, recording and querying longitudinal folding wing deployment time and rotation angle. It includes a folding wing measurement bracket and a display controller; the folding wing measurement bracket includes a rotating telescopic rod and a fixed telescopic rod, the fixed telescopic rod is parallelly fixed on both sides of the folding wing outlet on the surface of the missile, the rotating telescopic rod can rotate around the rotating axis, the folding wing rotates from between the fixed telescopic rods to between the rotating telescopic rods, and the release photoelectric sensor and the in-position photoelectric sensor are triggered in turn to generate signals, the signals are output to the display controller, converted into time and angle data through calculation and displayed, and the data is recorded and viewed through the function button. The invention supports simultaneous detection of multiple winglets.

[0024] Preferably, the folding-wing measuring bracket comprises a first connecting rod (1), an in-position photoelectric sensor (2), a rotating telescopic rod (3), a rotating shaft (4), a fixed telescopic rod (5), a release photoelectric sensor (6), a second connecting rod (7), an angle sensor (8) and a connecting cable (9); each end of the connecting rod is fixedly connected to a rotating telescopic rod, the fixed connection end of the rotating telescopic rod and the connecting rod is installed with the in-position photoelectric sensor, and the other end is connected to one end of the fixed telescopic rod through the rotating shaft, and similarly, the two fixed telescopic rods are also fixedly connected through the connecting rod, and the release photoelectric sensor is installed; the angle sensor is coaxially connected to the rotating shaft of one of the rotating telescopic rods, and the cables of the in-position photoelectric sensor, the release photoelectric sensor and the angle sensor are combined into a bundle of connecting cables and connected to the display controller.

[0025] The rotating telescopic rod and the fixed telescopic rod are respectively composed of an inner rod, an outer rod and a tension spring, and perform relative telescopic movement according to the measured length of the wing to control the length of the rod. The benefit is that it meets the measurement requirements of wings of different lengths and realizes contactless measurement of the wing deployment time.

[0026] Preferably, the connecting rod has a wire passing hole on its contact connection surface with the rotating telescopic rod and the fixed telescopic rod, and the cables of the in-position photoelectric sensor and the released photoelectric sensor are respectively combined into a bundle with the cable of the angle sensor through the wire passing holes of the connecting rod. The advantage is that the wire passing holes make it easy to install and disassemble the cables of the in-position photoelectric sensor and the released photoelectric sensor, prevent them from being squeezed, and simplify fixation.

[0027] Preferably, the in-position photoelectric sensor and the released photoelectric sensor use the same type of sensors, both consisting of a receiving end and a transmitting end, which are respectively installed on the symmetrical planes of the two telescopic rods, so that the receiving end can receive the infrared light signal of the transmitting end. When the wing passes between the receiving end and the transmitting end, the receiving end is blocked and cannot receive the infrared light signal. The advantage is that the distance between the receiving end and the transmitting end of the in-position photoelectric sensor and the released photoelectric sensor ensures that no contact is generated when the wing rotates, and when the receiving end is blocked by the wing, the photoelectric sensor generates an electrical signal and outputs it to the display controller.

[0028] Preferably, the angle sensor can only be coaxially connected to the rotating shaft of the rotating telescopic rod. When the rotating telescopic rod rotates at a certain angle, the angle sensor is driven to move in conjunction, while the fixed telescopic rod cannot rotate. The advantage is that when the fixed telescopic rod does not move, the angle sensor will accurately follow the rotating telescopic rod to reach the specified angle, and the rotation angle of the folding wing can be measured non-contactly over a large range, and a corresponding electrical signal is generated and output to the display controller.

[0029] Preferably, the display controller has a control circuit board, an LCD display module, function buttons, and a battery module inside; the power line of the battery module is connected to the control circuit board, the LCD display module, the angle sensor, the in-position photoelectric sensor, and the release photoelectric sensor. In addition to being connected to the battery module, the control circuit board is also connected to the function button, the LCD display module, the in-position photoelectric sensor, the release photoelectric sensor, and the angle sensor; a single group of folding wing measurement brackets includes an angle sensor and two photoelectric sensors, and can support the measurement of multiple groups of folding wing measurement brackets according to the number of pins of the main control chip on the control circuit board. Its benefits are that it can be converted into time and angle data for display through calculation and record and view data through the function button, and can perform simultaneous detection of multiple wings.

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] like Figure 1As shown, the folding-wing measuring bracket includes a connecting rod 1, an in-position photoelectric sensor 2, a rotating telescopic rod 3, a rotating shaft 4, a fixed telescopic rod 5, a released photoelectric sensor 6, a connecting rod 7, an angle sensor 8 and a connecting cable 9; the two ends of the connecting rod 1 are respectively fixedly connected to a rotating telescopic rod 3, the fixed connection end of the rotating telescopic rod 3 and the connecting rod 1 is installed with the in-position photoelectric sensor 2, and the other end is connected to one end of the fixed telescopic rod 5 through the rotating shaft 4, and similarly, the two fixed telescopic rods 5 are also fixedly connected through the connecting rod 7, and the released photoelectric sensor 6 is installed; the angle sensor 8 is coaxially connected to the rotating shaft of one of the rotating telescopic rods, and the cables of the in-position photoelectric sensor 2, the released photoelectric sensor 6 and the angle sensor 8 are combined into a bundle of connecting cables 9 to be connected to the display controller 10.

[0032] The rotating telescopic rod 3 and the fixed telescopic rod 5 are respectively composed of an inner rod, an outer rod and a tension spring. In a loose state, the telescopic rod is first extended to the required installation length, and then the inner rod is rotated inward to clamp it, and the clamping state can be released by rotating it outward, thereby realizing relative telescopic movement according to the length of different types of wings, controlling the length of the rod, and realizing contactless measurement.

[0033] The connecting rod 1 and the connecting rod 7 have wire holes dug on their contact connection surfaces with the rotating telescopic rod 3 and the fixed telescopic rod 5. The diameter of the wire holes should be 1.5 to 2 times larger than the diameter of the photoelectric sensor cable. This ensures that the cable will not be too loose or too tight when passing through the wire holes, facilitates installation and disassembly, prevents extrusion, and is simple to fix, so as to achieve better protection effect.

[0034] The in-place photoelectric sensor 2 and the released photoelectric sensor 6 are both composed of a receiving end and a transmitting end. They are fixedly installed in a U-groove structure and then installed on the symmetrical surfaces of the telescopic rod respectively. If the infrared light from the transmitting end is received by the receiving end, no action will occur. If the receiving end is blocked in the middle and does not receive the infrared light signal, the photoelectric sensor will generate an electrical signal and output it to the display controller.

[0035] The angle sensor 8 is kept on the same axis as the rotating shaft of the rotating telescopic rod, and the two are fixed together by mechanical fasteners. When the rotating telescopic rod rotates at a certain angle, the angle sensor is driven to move, while the fixed telescopic rod cannot rotate. Therefore, the measured angle range is large and can be rotated within 360°. In addition, the rotation angle measurement of the folding wing can be achieved by contactless measurement.

[0036] like Figure 2As shown, the display controller 10 includes a control circuit board, an LCD display module, function buttons, and a battery module; the battery module has a nominal voltage of 5V and is provided with a battery switch responsible for power on and off functions, and supplies power to the control circuit board, the LCD display module, the angle sensor, the in-position photoelectric sensor, and the release photoelectric sensor through a connecting cable; the control circuit board adopts a 51 single-chip microcomputer as the main control chip, which is connected to the battery module and is also connected to the input and output signal lines of the function button, the LCD display module, the in-position photoelectric sensor, the release photoelectric sensor, and the angle sensor; the LCD display module adopts an LCD1602A character-type liquid crystal display module, which can display general symbols such as English letters and Arabic numerals; the function button adopts a self-rebound button, which is pressed to open and released to rebound, and the 51 single-chip microcomputer outputs corresponding data to the LCD display module for display according to different function buttons.

[0037] The display controller can be connected to multiple sets of the same folding wing measuring brackets according to the number of wing pieces to be tested. Since a single wing piece is tested in this example, a single set of folding wing measuring brackets can meet the measurement requirements.

[0038] During implementation, the detection device of the present invention is used to detect the unfolding time and angle of the folding wing: first, turn on the battery switch of the display controller 10 to power on, and the LCD display screen works normally; then determine the placement position of the folding wing measurement bracket, wherein the fixed telescopic rod 5 is fixedly installed parallel to both sides of the folding wing outlet on the surface of the missile, and then the rotating telescopic rod 3 is rotated to a specified angle in advance, and the LCD display screen displays the angle data at this moment; when the folding wing receives the ejection command and the wing is unfolded from the missile body, the receiving end of the release photoelectric sensor 6 is blocked, and the sensor output signal changes from a low level to a high level (the sensor outputs a low level signal when the receiving end is not blocked), and the display controller starts timing when receiving the rising edge signal of the release photoelectric sensor 6; when the wing is unfolded and stopped, the receiving end of the in-position photoelectric sensor 2 is blocked, and the sensor output signal changes from a low level to a high level, and the timing ends when the display controller receives the rising edge signal of the in-position photoelectric sensor 2; the LCD display screen also displays the calculated unfolding time, and records and views the data through the function button.

[0039] The application scope of the present invention is not limited to the detection of the unfolding time and angle of the longitudinal folding wings, but can also be applied to the measurement of any rotation angle and time of other rotating objects.

[0040] The above-mentioned embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the present invention in any way. Any changes or substitutions that can be easily imagined are all within the scope of the technical solution of the present invention and should be included in the protection scope of the present invention.
