Personal GPS Tracker
Have you ever puzzled if you possibly can track an individual using an correct GPS gadget? Well, we assume that the government and spies have equipment like that the place they'll attach it to somebody or something and be capable to trace the route of the place it’s going and the place it’s actual location is. Well, with out doing all your research, you'd have never known. But sure, you'll be able to personal your personal personal GPS tracker. The TK102 is such a instrument, weighing in about 50 grams, it can easily be hid and tucked away someplace. All it's a must to do is slip a pre-paid simcard into the machine, and it’ll feed the knowledge to a cell tower nearby and back to your phone as a SMS message or to your computer. Yes, you can really get real time GPS tracking info and coordinates from this GPS tracking device. The knowledge you'll receive will be the latitude and longitude coordinates. It’s truly very simple to make use of these coordinates as we now have plenty of free tools that may assist us with that. You may plug the coordinates into Google Earth and you’ll see visually where this place is. So, for such a high tech GPS tracking device, how much would it not cost? The worth is about $50.00 which is extraordinarily inexpensive.
The invention relates to a big-angle clever photo voltaic tracker, which includes a moving platform and a hard and fast platform, and a first department chain I, lost item finder a second department chain II, a 3rd department chain III, and a fourth branch chain are installed between the moving platform and the mounted platform. IV, the first branch I and the third branch III have the identical construction and are symmetrically arranged, and the second branch II and the fourth department IV have the same construction and are symmetrically organized; the first department I contains the first connecting rod, and the first connecting rod The higher finish of the rod is related with the moving platform by means of the ball pair, the lower end of the primary connecting rod is connected with the primary Hooke hinge, and the primary Hooke hinge is linked with the fixed platform by means of the primary connecting block through the first moving pair; the second branch chain II Including the second connecting rod, the upper end of the second connecting rod is linked with the transferring platform through the second Hooke hinge, the decrease finish of the second connecting rod is linked with the second connecting block by the rotating pair, and the second connecting block and the mounted platform are moved by means of the second Secondary connection.
The 4 department chains of the present invention type a space parallel closed-loop structure with the transferring platform and the mounted platform, which might realize two-dimensional translation and two-dimensional rotational motion in area. 本发明属于并联机器人领域，特别涉及一种应用于定位、气象、雷达等环境下能够实现精确跟踪的四自由度单平台大转角智能太阳追踪器。 The invention belongs to the field of parallel robots, and lost item finder particularly pertains to a four-degree-of-freedom single-platform large-rotation-angle clever sun tracker that may realize precise tracking in environments comparable to positioning, meteorology, and radar. 并联机构通常由动平台、静平台及两平台之间的若干支链组成，具有刚度大、速度快、精度高的优点，在工业机器人、运动模拟器、并联机床等领域得到广泛应用。
近些年，国外已将陆续将部分机构构型应用于工业生产中（如:delta机构），而国内则较少，而且很少应用在生产生活中。 The parallel mechanism is usually composed of a dynamic platform, a static platform and several other branch chains between the two platforms. It has some great benefits of high rigidity, quick speed and high precision. It's extensively utilized in industrial robots, motion simulators, parallel machine tools and other fields. In recent times, overseas nations have successively utilized some mechanism configurations to industrial production (corresponding to: delta mechanism), while there are fewer home ones, and they are not often utilized in manufacturing and life. 在运动模拟器、姿态调平、太阳能追踪以及并联机床等领域，通常需要实现大位移、大转角，实现较大工作空间范围内的运动。
Within the fields of movement simulators, angle leveling, photo voltaic tracking, and parallel machine tools, it is normally essential to realize large displacements, massive rotation angles, and motions within a big working space. 国内太阳能发电普遍采用固定式太阳能电池安装方式，尽管这种安装方式结构简单、成本较低，但是无法精确跟踪太阳位置，光能转换效率较低。 现有研究中，也存在部分运动型太阳能机构，单轴或双轴等多为串联机构精度不高。 其中双轴的跟踪精度相对较高，太阳板能达到的转换效率相对较大，但遇到恶劣天气难以保证装置的安全性。
