Embodiment Construction

[0017] The invention includes a control instruction receiving circuit, an instruction decoding circuit, a power switch driving circuit, a power switch circuit, a bilateral level driving circuit and a control state sending circuit.

[0018] The control instruction receiving circuit is an RS232 signal receiver. The control instruction enters the RS232 signal receiver, and enters the asynchronous serial data receiving end of the instruction decoding circuit from its output end.

[0019] The instruction decoding circuit is the minimum application system of the known 51 series single-chip microcomputer, and the control instruction enters the single-chip microcomputer by the asynchronous serial data receiving end (RXD), and is identified by the known judgment method by software according to the agreed control instruction frame format and instruction code Write different control instruction codes, and then write the TTL level corresponding to this function (high level is "1", low lev...

Abstract

The invention discloses a small-sized airborne camera controller. The small-sized airborne camera controller is characterized in that a control instruction enters an instruction decoding circuit through an instruction receiving circuit, the instruction decoding circuit recognizes different control functional codes, then corresponding TTL (Transistor-Transistor Logic) level is written into data I/O (Input/Output) ports of the instruction decoding circuit, wherein one path enters a power source switch driving circuit which completes the on-off control on a camera power source, any two of the other six paths form a group which respectively enters inverse and same-phase input ends of a bilateral level driving circuit to complete the focal length control on a camera; and simultaneously, the TTL level is coded according to a stated frame formal and enters the input end of a control state transmission circuit through an asynchronous serious data transmitting end of a single-chip microcomputer to realize the real time monitoring on the control state of the camera. The small-sized airborne camera controller has the advantages that the circuits are simplified, the volume is reduced, the control state of the camera can be collected in real time, and the remote control and monitoring on the camera is realized.

Description

technical field [0001] The invention belongs to camera control technology, and relates to a control device for camera shooting function. Background technique [0002] At present, the known camera controller controls the power supply, focal length, aperture and lens of the camera through manual operation of mechanical buttons. Due to its bulky size, its application range is limited, and its application in UAVs with small spaces is severely restricted. It is used in the environment, especially the interface of the controller does not match the interface of the onboard computer of the UAV. Therefore, remote shooting of the camera cannot be realized on the ground. Contents of the invention [0003] In order to overcome the problem that the size, weight, and electrical interface of the existing camera controller do not match the airborne environment of the drone, the present invention provides a camera controller for the drone, which ensures that the power supply, focal length,...
