背景技术 Background technique
随着科学技术的发展,近年来数字信息化光电产品的研制和生产越来越多。其不仅既有红外、可见光双光学系统通道观察目标、激光测距的功能,还具有GPS/北斗卫星定位系统、电子罗盘等功能模块,通过各功能模块的集成,这样的光电产品可以很容易地确定本机的位置坐标,以及再依据所测定的观察目标与本机的距离、方位角度、俯仰角度等信息,从而就可以解算出所观察目标的经纬度、高程等,并且相关数据信息可以通过GPS/北斗卫星定位系统进行通信传输,也可以通过PDA、CRT(或是监视器)进行显示。信息数字化后,传输到更多需要的地方,将发挥更多效能,符合现代科技发展的需要,具有广阔的运用前景。为保证所观察目标坐标的精确性,光电产品上采用电子罗盘作为确定方位以及水平俯仰零位的功能模块,其感应地磁方位的精确度以及线性性能首当其冲成为最主要的决定因素。电子罗盘模块通过采样收集当地地磁场信息,并存储到其上的存储器上。在使用时,当产品转到不同的位置,电子罗盘上的传感器(包括方位传感器、俯仰传感器)与地磁场方向就有不同的位置关系,通过电子罗盘模块自身程序的解算,可以显示出电子罗盘与地磁场有不同的夹角,从而可以确定出产品所观察目标的地理方位角,以及产品所观察目标的俯仰角度。但由于实际产品使用环境复杂多变(比如使用地域不同,温度差异等),而会造成电子罗盘模块输出的数据各有差异。由此而影响到产品方位角、俯仰角的精度,进而使所观察目标的位置坐标解算受到影响。 With the development of science and technology, more and more research and production of digital information photoelectric products have been developed in recent years.

Through the integration of various functional modules, such optoelectronic products can be easily Determine the position coordinates of the machine, and then according to the measured distance between the observed target and the machine, azimuth angle, pitch angle and other information, so that the longitude, latitude, elevation, etc. of the observed target can be calculated, and the relevant data information can be obtained through GPS / Beidou satellite positioning system for communication transmission, and can also be displayed through PDA, CRT (or monitor). After the information is digitized, it will be transmitted to more places where it is needed, and it will exert more efficiency, which meets the needs of the development of modern science and technology, and has broad application prospects. In order to ensure the accuracy of the coordinates of the observed target, the electronic compass is used as the functional module to determine the azimuth and the zero position of the horizontal pitch in the optoelectronic products. The electronic compass module collects local geomagnetic field information through sampling, and stores it on the memory on it. When in use, when the product is turned to a different position, the sensors on the electronic compass (including azimuth sensor, pitch sensor) have different positional relationships with the direction of the earth's magnetic field. Through the calculation of the electronic compass module's own program, it can display the electronic There are different included angles between the compass and the geomagnetic field, so that the geographic azimuth of the target observed by the product and the elevation angle of the target observed by the product can be determined. However, due to the complex and changeable use environment of the actual product (such as different regions of use, temperature differences, etc.), the data output by the electronic compass module will be different. As a result, the accuracy of the azimuth and pitch angles of the product is affected, and the position coordinate solution of the observed target is affected.

本新型应用于精确检测和校正带有电子罗盘模块的光电产品的方位角、俯仰角精度。光电产品所使用的电子罗盘模块通过采样收集当地地磁场信息,并存储到其上的存储器上。在使用时,当产品转到不同的位置,电子罗盘上的传感器(包括方位传感器、俯仰传感器)与地磁场方向就有不同的位置关系,通过电子罗盘模块自身程序的解算,可以显示出电子罗盘与地磁场有不同的夹角,从而可以确定出产品所观察目标的地理方位角,以及产品所观察目标的俯仰角度。但由于实际产品使用环境复杂多变(比如使用地域不同,温度差异等),而会造成电子罗盘模块输出的数据各有差异。由此而影响到产品方位角、俯仰角的精度,进而使所观察目标的位置坐标解算受到影响。本新型优势在于充分考虑了电子罗盘的实际使用环境、集方位测角仪和俯仰角仪于一体,以及多种待校光电产品的结构,从而使调校的光电产品适用范围广,减少了产品的反复搬动,既提高了调校的精度,也降低了人力物力的损耗,同时也大大提高调校的工作效率。 The new type is used to accurately detect and correct the azimuth angle and pitch angle accuracy of photoelectric products with electronic compass modules. The electronic compass module used in photoelectric products collects local geomagnetic field information through sampling and stores it in the memory on it. When in use, when the product is turned to a different position, the sensors on the electronic compass (including azimuth sensor, pitch sensor) have different positional relationships with the direction of the earth's magnetic field. Through the calculation of the electronic compass module's own program, it can display the electronic There are different included angles between the compass and the geomagnetic field, so that the geographic azimuth of the target observed by the product and the elevation angle of the target observed by the product can be determined. However, due to the complex and changeable use environment of the actual product (such as different regions of use, temperature differences, etc.), the data output by the electronic compass module will be different. As a result, the accuracy of the azimuth and pitch angles of the product is affected, and the position coordinate solution of the observed target is affected. The advantage of this new model is that it fully considers the actual use environment of the electronic compass, integrates the azimuth goniometer and pitch angle meter, and the structure of various photoelectric products to be calibrated, so that the calibrated photoelectric products have a wide range of applications and reduce the number of products. The repeated movement not only improves the accuracy of the adjustment, but also reduces the loss of manpower and material resources, and also greatly improves the efficiency of the adjustment.
本新型的原理:如图2所示,将1#方位平行光管置于正北方位上(作为方位的零位基准,即方位零位管B)。以仪器中心为圆心,每间隔30°±1°放置一个平行光管作为一个方位标定点(整个360°水平方位范围内放置12个点),并用经纬仪确定各点的方位值(记录各个标定点的实际值,以便于调校中对比修正)。将产品方位旋转轴置于仪器中心,使产品正对1#方位平行光管时,对应安装在产品上的电子罗盘会有一角度输出值。然后修正产品上罗盘读出电路板程序的相关参数,以使显示出来的方位角度值为零,由此校正好产品的方位零位。再依次将产品旋转至观察其它方位标定点,并记录各点的方位实际显示值,比较各实际显示值与标定值的偏差情况,通过读出板的程序进行分段修正各点的方位值。最终使方位实际显示值与标定值的误差在产品要求的精度范围内。 The principle of this new model: as shown in Figure 2, the 1# azimuth collimator is placed on the north position (as the zero reference of the azimuth, that is, the azimuth zero tube B). With the center of the instrument as the center, place a collimator at an interval of 30°±1° as an azimuth calibration point (12 points within the entire 360° horizontal azimuth range), and use theodolite to determine the azimuth value of each point (record each calibration point The actual value, in order to facilitate comparison and correction in the adjustment). Put the azimuth rotation axis of the product in the center of the instrument, so that when the product is facing the 1# azimuth collimator, the corresponding electronic compass installed on the product will have an angle output value. Then correct the compass on the product to read out the relevant parameters of the circuit board program, so that the displayed azimuth angle value is zero, thereby correcting the product's azimuth zero. Then rotate the product to observe other azimuth calibration points in turn, and record the actual display value of the azimuth at each point, compare the deviation between the actual display value and the calibration value, and correct the azimuth value of each point in sections through the program of the readout board. Finally, the error between the actual display value and the calibration value of the azimuth is within the accuracy range required by the product.
同样的,对于俯仰测角仪首先调节器支架安装面处于水平面内,用经纬仪检测俯仰测角仪的水平零位管的光轴应处于水平面内,且与周圈方位平行光管的中心相交。然后再依次标定其余各俯仰平行光管的角度值,并作记录,以便于调校中对比修正。调校时,当光电产品正对俯仰角零位管A时,修正产品上俯仰读出电路板程序的相关参数,以使显示出来的方位角度值为零,由此校正好产品的俯仰零位。再依次将产品俯仰旋转至观察其它俯仰标定点,并记录各点的俯仰实际显示值,比较各实际显示值与标定值的偏差情况,通过读出板的程序进行分段修正各点的俯仰值。最终使俯仰实际显示值与标定值的误差在产品要求的精度范围内。 Similarly, for the pitch goniometer, the mounting surface of the adjuster bracket is first in the horizontal plane, and the optical axis of the horizontal zero tube of the pitch goniometer detected by the theodolite should be in the horizontal plane and intersect with the center of the circumferential azimuth collimator. Then calibrate the angle values of the remaining pitch collimators in turn, and record them for comparison and correction during calibration. When adjusting, when the photoelectric product is facing the pitch angle zero position tube A, correct the relevant parameters of the pitch readout circuit board program on the product so that the displayed azimuth angle value is zero, thereby correcting the pitch zero position of the product . Then rotate the product in turn to observe other pitch calibration points, and record the actual display value of the pitch at each point, compare the deviation between the actual display value and the calibration value, and correct the pitch value of each point in sections through the program of the readout board . Finally, the error between the actual display value and the calibration value of the pitch is within the accuracy range required by the product.
