Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.
Embodiment one: transmission line of electricity 2 is located at aerial certain altitude usually by several tower bridges, in space between adjacent two tower bars, arrange a range finding alarm 4 transmission line of electricity 2 between the two tower bar is monitored, when find threaten transmission line of electricity 2 object occur time can and alarm.Range finding alarm 4 is installed on a tower bar and towards its another adjacent tower bar. Range finding alarm 4 adopts laser sensor, whether its its launch party of detection that can give off laser beam upwards has object on the one hand, on the other hand, laser measurement object and distance between can also be passed through when finding object, and report to the police when distance is in set point. The electric transmission line channel protection alarm method of the present invention is just applied in this range finding alarm 4; range finding alarm 4 is arranged on tower bar and is positioned at certain height place below transmission line of electricity 2 to be protected; this height delimited a protection zone 3; this region is monitored by range finding alarm 4, judges whether there is the object threatening transmission line of electricity 2 channel security in this protection zone 3.
As shown in Figure 2, it is the top view in space between two shaft towers 1. Generally, the line at the two ends of the transmission line of electricity 2 between two shaft towers 1 is approximately parallel to the ground between two shaft towers 1, and the plane at place, protection zone 3 is also parallel with the line at transmission line of electricity 2 two ends. The protection zone 3 delimited is rectangle, and its four edges constitutes four edges circle of protection zone 3. The line at the two ends of transmission line of electricity 2 to be protected is parallel to the limit that a length is L of rectangle and arranges, and transmission line of electricity 2 is positioned at the middle part of protection zone 3. Protection zone 3 is divided into left and right two parts by the line at transmission line of electricity 2 two ends, this two-part width respectively L1 and L2. Range finding alarm 4 is installed on a shaft tower 1 thus it is positioned on a border of protection zone 3.
For the right half part of the protection zone 3 shown in accompanying drawing 2, the electric transmission line channel protection alarm method of the present invention is as follows:
(1) protection zone 3 of right half part is divided into (n+m) sub regions (n, m are positive integer). The border of every sub regions is constituted by three parts: two with alarm 4 of finding range be intersection point straight border and the border of part protection zone 3; make every sub regions be triangle, in every sub regions two with alarm 4 of finding range for pan angle, �� that the angle between the straight border of intersection point is this subregioni, wherein i=1,2 ..., (n+m).
These subregions can be divided into again two classes: n the first subregion and m the second subregion. First subregion is: the border of the part protection zone 3 that it comprises is positioned on the opposite side of rectangular edges at distance measuring sensor place; Second subregion is: the border of the part protection zone 3 that it comprises is positioned on the adjacent side of rectangular edges at distance measuring sensor place.
(2) the guard space limit value S of every sub regions is determinedi, wherein i=1,2 ..., (n+m).
In the first subregion, its guard space limit value Si(i=1,2 ..., n) for its two be one longer in the straight border of intersection point with alarm 4 of finding range length. Still for the right half part of the protection zone 3 shown in accompanying drawing 2; if the length of line projection on protection zone 3 is S between transmission line of electricity 2 two ends; it is the straight line border of first the first subregion in right side, and the length of another straight border of this first subregion is S1, then obvious S1More than S, then on the right side of this, the guard space limit value of first the first subregion is just for S1. Length is S1This straight border be also the straight line border of second the first subregion in right side simultaneously, on the right side of this, the length of another straight border of second the first subregion is S2, S2More than S1, then the guard space limit value of second the first subregion in right side is just for S2.By that analogy, the guard space limit value of each the first subregion is S1��S2������Sn. The border of each the first subregion also includes the border of the protection zone 3 of segment rectangle, in each first subregion, its be positioned at range finding limit, alarm 4 place opposite side on border length for its sweep from, the pan of each the first subregion, apart from identical, is K.
In second subregion, its guard space limit value Si(i=n+1, n+2 ..., n+m) for its two be one shorter in the straight border of intersection point with alarm 4 of finding range length. For the right half part of the protection zone 3 shown in accompanying drawing 2, the longest straight line border is the line between the opposite side end points of the protection zone 3 of range finding alarm 4 and rectangle, and its length is Sn, and the straight border in each second subregion is gradually shortened, if each bar straight border dividing each the second subregion is followed successively by Sn+1��Sn+2������Sn+m, then it can be seen that the guard space limit value respectively S of each the second subregionn+1��Sn+2������Sn+m. In each second subregion; the intersection point that its two is one shorter in the straight border of intersection point and border, protection zone 3 with alarm 4 of finding range sweeps distance to the distance of another straight border for it; the pan of each the second subregion is apart from identical; and it is also identical with the pan of each the first subregion distance; it is all K, usual K to be divided exactly by length of side L and L1, the L2 of rectangle protection zone 3.
(3) each sub regions swept successively by range finding alarm 4, and alarm 4 of finding range in every period of second unit interval s is according to pan angle, ��iSweep a sub regions. Whole pan angular ranges of range finding alarm 4 are 180 ��
Pan angle, �� in every sub regionsiIn, if range finding alarm 4 is detected with object, then it measures the distance between the object detected and range finding alarm 4, and this distance can be the meansigma methods in the unit time, this object found range. Then, it is judged that whether the distance between the object that detects and range finding alarm 4 is less than or equal to the guard space limit value S of this subregioni(i=1,2 ..., n+m). If so, then there is the object threatening transmission line of electricity 2 channel security in this subregion, now, range finding alarm 4 is reported to the police.
Range finding alarm 4 is swept the process of each sub regions and is undertaken by the driving of drive motor. Drive motor drives a rotation platform to rotate by decelerator, and range finding alarm 4 is arranged on this rotation platform such that it is able to synchronous axial system. The original position of pan is on the vertical plane at the line of centres place of two steel towers. The motor selected or the rotating speed of servomotor are YY revolutions per second, send driver BB pulse meeting drive stepping motor of motor or servomotor or servomotor to rotate a circle. The speed reducing ratio of the rotation platform selected is NN:1. The number of drive pulses then sent needed for every S second anglec of rotation is (��i* BB/360) * NN. Scanning protection zone, whole right side required time is S*(n+m).
