Technical field
The present invention relates to a kind of auto photographing device that is used for the investigation of oncomelania and other terrestrial biological resources, can realize that two kinds of control modes of program setting and remote control take pictures, store, carry out the investigation work of oncomelania and other terrestrial biological resources, the genus environmental science.
Background technology
The distribution situation of obtaining oncomelania and other earth's surface biological has important meaning in different field; As the distribution situation of obtaining oncomelania is the important means of prevention and control snail fever, and obtaining the face of land, forest zone reptile distribution situation has very big reference value or the like to the reasonability and the forestry protection of assessment forestry activities.It mostly is to search through manual type that present oncomelania and other earth's surface biological are searched; Search like oncomelania and to carry out naked eyes through artificial hauling type operation exactly and search this mode length consuming time, inefficiency; Need the labor manpower and materials, and exist and many unfavorable factors such as artificially judge, misjudge and fail to judge by accident.
Summary of the invention
The objective of the invention is to develop a kind of auto photographing device that is used for oncomelania and the investigation of other terrestrial biological resources; This device can realize that program setting and two kinds of control modes of remote control take pictures, store, and carries out the investigation work of oncomelania and other terrestrial biological resources.
Search the deficiency of mode in order to overcome existing earth's surface biological; The present invention provides a kind of oncomelania and other earth's surface biological to search automatically; And the device of the storage of taking pictures, this device can not only realize that the program setting route searches, and can also realize that the manual remote control mode searches; Dual mode complements one another, and can supply to take pictures monitoring by the real-time Transmission image scene during work.
The technical solution adopted for the present invention to solve the technical problems is: the remote control four-wheel drive climbing dolly that camera is housed; It advances, retreats, stops, turning to, focus, takes pictures and function such as storage by single chip circuit control, also can accomplish above function by remote.
The present invention mainly comprises remote controller and dolly two large divisions; Wherein remote controller is made up of three parts; First comprises control button, steering tiller, eight passage proportional remote controls, radiating circuit, and this partial circuit can be accomplished the remote control control to the actions such as advancing, turn to of dolly.Second portion comprises control button, coding circuit and wireless switching, radiating circuit, and this part can accomplish that dolly is program control, the switching of remote control, and the open and close machine of in-vehicle camera, focusing, camera function.Third part comprises wireless video reception, commutation circuit, display screen and drive circuit thereof, and this part is mainly accomplished monitoring function, through receiving the vision signal that dolly sends, is shown the video signal of in-vehicle camera output in real time by display screen on the remote controller.
Dolly mainly is made up of 1: 8 four-wheel drive climbing car, digital camera and a control circuit; Wherein control circuit comprises five parts; First is made up of single chip machine controlling circuit and display screen, and this partial circuit is accomplished all controls to dolly, and through the display screen display control information.Second portion is made up of proportional remote control receiving circuit and power motor, steering-engine, and this part can be accomplished the receiving function to remote signal, and drives power motor and steering-engine is accomplished the function of advancing, retreating and turn to.Third part mainly is made up of Hall element, through the detection that power motor is rotated, cooperates single chip machine controlling circuit can accurately control the distance of trolley travelling.The 4th part is made up of the wireless switching receiving circuit, and this part is through to the reception of remote control switch signal, cooperates that single chip machine controlling circuit is accomplished logarithmic code camera open and close machine, function such as focus and take pictures, and also can accomplish dolly remote control/program control handoff functionality.The 5th part is made up of multiple wireless video transmission circuit, and this partial circuit is responsible for launching the vision signal of digital camera output, supplies remote controller to receive, monitor in real time.
Single chip machine controlling circuit mainly is made up of the 89S52 that a slice atmel corp produces among the present invention, is equipped with 8 and touches keyboard, can the basic function of dolly be provided with.
The invention has the beneficial effects as follows through the motion of dolly and automatic camera, the storage of digital camera; Accomplish taking pictures of table section over the ground; For later image identification provides raw data; Can save plenty of time and manpower and materials, improve the efficient that oncomelania and other earth's surface biological are searched, for corresponding field provides bio distribution data comparatively accurately.
The auto photographing device volume of this oncomelania and the investigation of other terrestrial biological resources is little, and total weight adopts storage battery power supply less than 20 kilograms, can under multiple environmental conditions such as nonirrigated farmland, wet ground, marsh, work.

Embodiment
Below in conjunction with accompanying drawing and execution mode the present invention is further specified.
This device mainly is made up of remote controller and dolly, and wherein dolly is converted by a commercially available climbing car 2 of 1: 8, and the structure of climbing car repeats no more.Fixing digital camera 3 on the car, camera lens down, about 30cm apart from ground.Digital camera mains switch button, focusing tripper are all drawn through circuit, are connected to single chip machine controlling circuit, can be focused and taken pictures by the open and close of Single-chip Controlling digital camera power supply.Mainly introducing this device below is how to realize automatic photo function.
Behind the power supply, single chip machine controlling circuit is started working on the unlatching dolly, and the display screen demonstration is provided with the interface, and can set the trolley travelling parameter this moment, as: the spacing of adjacent twice trolley travelling of taking pictures, the cycle of taking pictures etc.After setting, dolly can move according to the parameter that configures automatically, and the effect of operation is:
1, dolly advances.
2, advance after the X rice, stop.(X can set when start)
3, open digital camera mains switch on the dolly automatically, automatically focused, take pictures in the face of land.
4, take pictures after, dolly gets into next circulation---advance → stop → focusing, take pictures.
5, Y all after dates have been carried out when circulation, the dolly entering holding state that stops.(Y can set when start)
If above process remote controller sends remote signal, Automatic Program stops, and dolly is controlled by remote controller.
The control that turns to, advances, retreats on the remote controller belongs to former climbing car proportional remote control control mode, repeats no more at this.Other has button 11,12,13, presses the back through behind the radiating circuit coding, launches, receive and, deliver to single chip machine controlling circuit and drive digital camera via dolly through after the receiving circuit decoding, respectively the mains switch of corresponding digital camera, focus and take pictures.Button 10 is remote control/program control selector buttons, can realize remote control and programme controlled switching of dolly after pressing.Liquid crystal display screen is housed on the remote controller, delivers to multiple wireless video transmission circuit after the digital camera vision signal on the dolly is drawn and launch, after the video reception circuit on the remote controller receives, by 6 display frames of the liquid crystal display screen among Fig. 2, monitoring digital camera realtime graphic.
