Abstract
The utility model discloses a wireless liquid crystal instrument for an electric bicycle. In the wireless liquid crystal instrument for the electric bicycle , the instrument consists of a liquid crystal displayer, an instrument single chip microcomputer and a battery, wherein a controller consists of a controller single chip microcomputer and a power circuit, the instrument single chip microcomputer is connected with an instrument wireless transceiving module by a transceiving control line, and signals are transmitted between the instrument wireless transceiving module and the instrument single chip microcomputer; and the controller is internally provided with a controller wireless transceiving module, and the signals are transmitted between the controller wireless transceiving module and the controller single chip microcomputer. In the wireless liquid crystal instrument, not only the connecting wire harness between the instrument and the controller can be omitted, but also the wireless instrument is designed into a mode that a signal mainly controls a transceiving signal and the controller is controlled to transceiving the signals by using the characteristic of quick data transmitting speed of the wireless carrier signals, thereby greatly reducing the power consumption of a wireless transceiving circuit.
Description
Technical field
The utility model relates to the Electrical Bicycle field of display, more particularly, relates to the wireless liquid crystal instrument of a kind of Electrical Bicycle.
Background technology
Electrical Bicycle generally adopts the wire signal transmission with telltale at present.For high-grade battery-driven car, owing to the difference of cycle frame, need the wire harness of different length customized, this is concerning battery-driven car instrument manufacturing enterprise, and the instrument of different wire length customized is things that waste time and energy, and is unfavorable for batch manufacturing.So utilize public wireless frequency range design wireless electric auto meter that the market demand has just been arranged, can save the rattail between instrument and the controller like this.
The automatically controlled core component of Electrical Bicycle is a controller, and for the battery-driven car of wired connection instrument, its display instrument is the annex existence as control system, so the circuit of battery-driven car instrument is in wait reception data mode mostly.If according to this Design Pattern wireless instrument, the wireless receiving of battery-driven car instrument and radio transmitter will be in running order always.
Because wireless receiving and radio transmitter need power consumption, be the key that determines that can wireless instrument practicability the service life of for the battery-driven car wireless instrument of dry cell power supply for, reduce power consumption, improving dry storage battery.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, provides a kind of Electrical Bicycle wireless liquid crystal instrument.
The wireless liquid crystal instrument of the utility model Electrical Bicycle, be achieved by following technical proposals, instrument is made up of Liquid Crystal Display (LCD), instrument micro controller system and battery, controller is made up of controller micro controller system and power circuit, it is characterized in that, described instrument micro controller system is connected with the instrument radio receiving transmitting module by the transmitting-receiving control line, carries out the signal transmission between instrument radio receiving transmitting module and the instrument micro controller system; The controller radio receiving transmitting module is set in the described controller, carries out the signal transmission between controller radio receiving transmitting module and the controller micro controller system.
In instrument radio receiving transmitting module described in the utility model and the controller radio receiving transmitting module wireless receiving and transtation mission circuit are set respectively.
The utility model stepping can save the rattail between instrument and the controller, and utilize wireless carrier signal to transmit very fast these characteristics of data speed simultaneously, wireless instrument is designed to signal master control receiving and transmitting signal and the controlled receiving and transmitting signal pattern of controller, can reduces the power consumption of wireless transceiver circuit significantly.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, instrument is made up of Liquid Crystal Display (LCD), instrument micro controller system and battery, controller is made up of controller micro controller system and power circuit, described instrument micro controller system is connected with the instrument radio receiving transmitting module by the transmitting-receiving control line, carries out the signal transmission between instrument radio receiving transmitting module and the instrument micro controller system; The controller radio receiving transmitting module is set in the described controller, carries out the signal transmission between controller radio receiving transmitting module and the controller micro controller system.Black arrow is represented the transfer of energy route among the figure, blank arrow representation signal transfer route.Wherein instrument radio receiving transmitting module and controller radio receiving transmitting module can adopt models such as JF24D.
The utility model principle of work is as follows: allow the wireless transceiver circuit of instrument be in closed condition at ordinary times, when instrument receive control the instruction that button transmits by the instrument micro controller system after, handle the back by transmitting-receiving control line open wireless transmission circuit by instrument circuit, be transferred to controller at a terrific speed according to specific form, close wireless transceiving modes then.After controller is received instrumented data, send at a terrific speed according to the data after the time handle processing of agreement in the instrument instruction.Instrument is opened wireless receiving circuit in the time of agreement in advance, after finishing data sink, closes wireless transceiver circuit, gets back to little power consumption mode.The wireless transceiver circuit of instrument just is in the gap mode of operation of very short time like this, can reduce the average working current of instrument significantly, thereby significantly prolongs the service life of battery.
Embodiment recited above is described the utility model preferred implementation; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; common engineering staff make the technical solution of the utility model in this area various distortion and improvement all should belong to protection domain of the present utility model.
