Description

A kind of remote control module of multi-functional anti-co-channel interference
Technical field:
The utility model relates to wireless remote control system, specifically a kind of remote control module of the multi-functional anti-co-channel interference for remote controlled electric car.
Background technology:
Existing civil radio telechirics forms by transmitting and receiving two parts, and radiating portion forms the emission telepilot by coding IC, transmitter module, emitting antenna, control button and power supply (battery) and shell; Receiving unit is comprised of receiver module, decoding IC or software decode and control circuit.The coded system of launching code IC commonly used has two types of fixed code and rolling codes.Emission control all is by sending out control key even the mode of operation that supervention is penetrated; The remote signal transmission is with the digital address, the data signal modulation carrier transmit, and with the amplitude modulation pattern for the most commonly used, this remote signal transmission exists under the same carrier modulation, when several telepilots use in remote range simultaneously, Chang Yintong frequently between phase mutual interference and produce problem out of control, particularly in the control of remote controlled electric car is used, because turning to, it is the continuous crawl control mode of signaling, adopt this mode, wireless remote control system both may be in and send the interference duty, also may be in the duty that is disturbed, thereby make remote controlled electric car out of control and produce various adverse consequencess.
The utility model content:
The purpose of this utility model just provides and a kind ofly can effectively reduce the wireless remote control co-channel interference, improves the reliability of straighforward operation, and has the remote control module from the multi-functional anti-co-channel interference of the functions such as motion tracking, Speed display, electric weight demonstration.
For achieving the above object, the utility model comprises module, described module comprises display interface, single-chip microcomputer, battery voltage sampling interface and control button Sampling Interface, and described display interface, single-chip microcomputer, battery voltage sampling interface and control button Sampling Interface all are welded on the printing board PCB; Burn in the described single-chip microcomputer novel coding and signaling program are arranged.
The utility model is owing to adopted burning that the single-chip microcomputer of novel coding and signaling program is arranged, can take short code (8 bit address+4 bit data) to cooperate the soldier to send out technology (time-division multiplex technology), it is very little by (〉=1: 10) to reach every group of signaling dutycycle, thereby reach in the emission space section, hold a plurality of simultaneously numeric data codes of emission, greatly reduce a plurality of telepilots at one time, the probability of the co-channel interference that produces when using in the same remote range, and can cooperate diphase code (Manchester code) as the basis, utilize quadrature technique that information is encoded, in each cycle, utilize the variable period method to launch two groups of information, frequency spectrum according to secondary information when receiving end is decoded is different, come information extraction through relevant comparison operation and digital filtering, reach the raising decoding reliability, remedy the negatively influencing of discontinuous signaling, can take besides to increase the specific function coded order signal that transmission buttons to end, make receiving end correctly judge the button control action, improve the anti-electromagnetic interference (EMI) measure of control reliability; It is to utilize idle numeric data code as specific automatically tracking code signal from the motion tracking coded signal, and take idle timing automatic code sending method, namely in free time of the emission of button not, regularly 1-2 sends second automatically, in a single day receiving end determines can not receive this signal, just out of service, run out of remote range and problem out of control thereby solve the remote controlled electric car accident; In the speed regulating telecontrolled signal that sends, the appointment a data is speed threshold, and receiving end changes by this speed threshold Data Control speed of a motor vehicle, makes the speed stage of telepilot show with consistent by telecar speed the blind control problem of the speed that can solve; Utilize the A/D interface of single-chip microcomputer to detect cell voltage, and the output indicator signal, reminding user is in time changed battery, guarantees the intensity of remote-transmitter.
This utility model is compared with conventional art has following good effect:
1, in actual use, a plurality of telepilot simultaneously, with the straighforward operation of remote range mutually without impact;
2, when remote controlled electric car is run out of remote range, can be at timely automatic stopping of 1~2 second time;
3, have the speed synchronizing function, the personnel of controlling can know the actual vehicle speed of electric golf-ball-bag vehicle at a distance from the demonstration of telepilot;
4, adopt the telepilot of this module, the control continuous action when (turning to) without interrupting break.
Description of drawings:
Fig. 1 is theory diagram of the present utility model;
Fig. 2 is application synoptic diagram of the present utility model;
Fig. 3 is physical circuit figure of the present utility model.
Embodiment:
Shown in Fig. 1 to Fig. 3 is an embodiment of the present utility model, the utility model comprises module 1, described module 1 comprises display interface 11, single-chip microcomputer 12, battery voltage sampling interface 13 and control button Sampling Interface 14, and described display interface 11, single-chip microcomputer 12, battery voltage sampling interface 13 and control button Sampling Interface 14 all are welded on the printing board PCB.Described single-chip microcomputer 12 interior burnings have novel coding and signaling program.
During practical application, the display interface 11 of module 1 is connected with speed stage and electric-quantity display device 2, and the control button Sampling Interface 14 of module 1 is connected with control button serial connection group 3, and the single-chip microcomputer 12 of module 1 is connected with transmitter module 4, thereby consists of telechirics.
