Problems solved by technology
The previous zero-position memory devices used mechanical memory devices, such as engraved lines, scales, etc., in the harsh external environment, when the accuracy itself could not meet the index requirements, its own reliability could not be guaranteed. In this case, a more convenient method is urgently needed to realize the angle zero memory function

Embodiment Construction
[0020] see Figure 1-Figure 3 , the present invention relates to an angle zero memory device based on laser ranging, which includes a transmitting device 1 and a reflecting device 2. The transmitting device 1 is installed on the support plate of the antenna transmission structure, and the reflecting device 2 is installed on the rotation of the antenna transmission structure. on the disk, where:
[0021] The transmitting device 1 includes a shell 1.1, an upper plate 1.2, a lower plate 1.3, a laser transmitter 1.4, a fixing bar 1.5, a battery box 1.6, and a wiring hole 1.7. The shell 1.1 is a square structure, which is only a tetrahedron, hollowed out up and down It is used to place the upper plate 1.2 and the lower plate 1.3. There is a box at the top and bottom of the four corners. The center of the box has a through-hole thread with self-locking function. The sides of the shell are folded and holes are opened for overall installation. The shell 1.1 A battery box 1.6 and wiri...

The present invention relates to an angle zero position memory method based on laser distance measurement. A laser distance measurement method is employed to synchronously collect a distance measurement value and an antenna angle, a laser emitter is fixed in a housing, unoccupied portions in the housing are filled with foam filling agent to ensure damping and fixing effects, and a reflector fixedon a rotary table is rotated to ensure that the laser of the laser emitter can radiate to the right place. In a condition that the laser emitter is electrified, the antenna is rotated, distance measurement data of a data processing unit is observed, when big change of data occurs at the first time, the rotation speed of the antenna is reduced, and when big change of data occurs at the second time,a current angle is recorded, namely an angle zero position; a mode of real-time and later data comparison is employed, the same interruption and the same B code are used to ensure the time consistence, and a corresponding angle is antenna zero position at the moment when the big change of the data occurs at the second time. The angle zero position memory method based on the laser distance measurement is convenient to implement, has an angle zero position memory function and has a very high application value.
Description
technical field [0001] The invention relates to an angle zero memory method based on laser ranging. It belongs to the field of aerospace measurement and control technology. Background technique [0002] The shipborne measurement and control servo system is the "portal" of the entire measurement and control system. It is used to lock and track the target "fast, accurate and stable". It adopts the deviation tracking method. The deviation is finally converted into an angle to guide the antenna to follow the target. Angle encoder provided. In order to unify the coordinate system, the shaft angle encoder of the measurement and control antenna needs to calibrate the zero position. Since the shaft angle encoder is an electronic device, the zero position value needs to be re-entered after the fault is replaced. At this time, the zero position memory device will provide the zero position value as a reference . The previous zero-position memory devices used mechanical memory device...
