Automatic agricultural-machinery intelligent terminal box based on Beidou positioning

Abstract

The invention provides an automatic agricultural-machinery intelligent terminal box based on Beidou positioning. The terminal box comprises a fixing mechanism, wherein a set of waist circular holes which are convenient to fix are formed in the fixing mechanism, a heat dissipation mechanism is fixed on the fixing mechanism through bolts, and the fixing mechanism is connected with an agricultural machine; the fixing mechanism is provided with four step holes which facilitate connection of screws and the terminal box, the terminal box is provided with a circuit board, and the heat dissipation mechanism is connected with the circuit board on the terminal box; and elastic seats A are arranged the positions, beside the waist circular holes, of a base, the structures of the elastic seats A are the same as those of elastic seats B, a fixing bolt with a ratchet-shaped fixing block is arranged on each waist circular hole, a damping seat with a threaded connection is arranged on each fixing bolt,and each damping seat is composed of two hexagonal nuts. When the base is connected with a machine body through the fixing bolts, the elastic seats A prevent the fixing bolts from loosening, the agricultural machine generates large vibration during work, and the terminal box is shock-reduced after installation of the damping seats.

Description

technical field [0001] The invention belongs to the technical field of Beidou positioning, and more specifically relates to an intelligent terminal box for automatic agricultural machinery based on Beidou positioning. Background technique [0002] The Beidou satellite navigation system consists of three parts: the space segment, the ground segment and the user segment. It can provide high-precision, high-reliability positioning, navigation, and timing services for all types of users around the world, all-weather, and has short-message communication. It has initially possessed regional navigation, positioning and timing capabilities, with a positioning accuracy of 10 meters, a speed measurement accuracy of 0.2 m / s, and a timing accuracy of 10 nanoseconds. With the development of science and technology and agriculture, more and more agricultural machines are equipped with smart terminal boxes positioned by Beidou, and agricultural machine automation has been successfully appli...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides an automatic agricultural machinery intelligent terminal box based on Beidou positioning, to solve the problem that the terminal box will generate a large vibration when the agricultural machinery is working, and the signal receiving head is easy to change the receiving direction, which affects the stability of the signal ;The terminal box will resonate when the agricultural machinery is working, which is easy to cause damage to the internal circuit board of the terminal box. The terminal box is exposed to the outside all the year round, and the connection of the terminal box is sealed by a rubber ring. The existing rubber ring has a relatively simple structure and poor waterproof effect. The heat dissipation holes have a poor waterproof effect on the inside of the terminal box, and it is easy to cause damage to the internal circuit of the terminal box
