Accompanying drawing explanation
Fig. 1: the automobile remote-control electronic lock system schematic diagram that the utility model embodiment provides.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only for explaining the utility model, and be not used in restriction the utility model.
Fig. 1 shows an embodiment of the automobile remote-control electronic lock system that the utility model provides.This system comprises remote controller 1 and car-mounted terminal 2.Remote controller 1 comprises the first microcontroller 11 and connected the first variable ratio frequency changer radio-frequency (RF) receiving and transmission module 12; Car-mounted terminal 2 comprises the second microcontroller 21 and connected the second variable ratio frequency changer radio-frequency (RF) receiving and transmission module 22 of difference and vehicle-mounted servo module 23.The first microcontroller 11 is by the first variable ratio frequency changer radio-frequency (RF) receiving and transmission module 12 transmit operation orders, the second microcontroller 21 receives operational order by the second variable ratio frequency changer radio-frequency (RF) receiving and transmission module 22, and according to the vehicle-mounted servo module 23 of this operational order control, automobile is carried out and locked or unlocking operation, simultaneously, the operation that the second microcontroller 21 returns to vehicle-mounted servo module 23 by the second variable ratio frequency changer radio-frequency (RF) receiving and transmission module 22 completes confirmation and sends, and the first microcontroller 11 receives this operation by the first variable ratio frequency changer radio-frequency (RF) receiving and transmission module 12 and completes confirmation.On remote controller 1, be also provided with result indicating module 13, the operation that result indicating module 13 can receive according to the first microcontroller 11 completes confirmation and makes corresponding indication, thus the operating result of prompting user to automobile.Result indicating module 13 can adopt vibration unit, LED luminescence unit or display screen etc., by vibration, luminous or point out user in modes such as display screen demonstrations.On remote controller 1, be provided with the function button 14 being connected with the first microcontroller 11, as the button of locking, unlock button, seek car button, the alert button etc. that disappears, user can select corresponding operational order by these function buttons 14.
For avoiding when system is subject to signal interference, the operation command signal that remote controller 1 sends can not normally be received by car-mounted terminal 2, causes car-mounted terminal 2 normally to automobile, not carry out the operational order that remote controller 1 send, and native system has added anti-interference function.Particularly, native system be realize so jamproof: the frequency hopping table of the first variable ratio frequency changer radio-frequency (RF) receiving and transmission module 12 and the second variable ratio frequency changer radio-frequency (RF) receiving and transmission module 22 is set to identical, the second variable ratio frequency changer radio-frequency (RF) receiving and transmission module 22 is carried out frequency hopping and is patrolled and examined according to the frequency hopping table of setting, and completing the time that a frequency hopping table patrols and examines is a polling period.According to normal workflow, the first microcontroller 11 is by the first variable ratio frequency changer radio-frequency (RF) receiving and transmission module 12 transmit operation orders, and meanwhile, whether inspection vehicle mounted terminal 2 returns and operated confirmation.Now, the first variable ratio frequency changer radio-frequency (RF) receiving and transmission module 12 is operated on a communication frequency.It is to be noted, the operation command signal sending with a frequency need to continue the time of at least one above-mentioned polling period, can guarantee that like this second variable ratio frequency changer radio-frequency (RF) receiving and transmission module 22 patrols and examines this frequency in this polling period, thereby set up communication with the first variable ratio frequency changer radio-frequency (RF) receiving and transmission module 12, be connected.If being subject to signal in this frequency, system disturbs, the first variable ratio frequency changer radio-frequency (RF) receiving and transmission module 12 cannot be set up communication with the second variable ratio frequency changer radio-frequency (RF) receiving and transmission module 22 and is connected in this frequency, like this, car-mounted terminal 2 just cannot be carried out corresponding operation to automobile according to the operational order of remote controller 1, also can not return and operate confirmation to remote controller 1.The first microcontroller 11 transmit operation orders, and wait for after at least one above-mentioned polling period, if also do not receive that the corresponding operation sending it back from car-mounted terminal 2 completes confirmation order, the system that is judged as has been subject to signal interference, now, the first microcontroller 11 is controlled the first variable ratio frequency changer radio-frequency (RF) receiving and transmission module 12 and to next communication frequency continuation, is sent origin operation order according to the order frequency hopping of frequency hopping table, until the first microcontroller 11 receives, has operated confirmation.For the frequency sweep of the device of avoiding being interfered, disturb, frequency hopping table is set to the mode different from the frequency sweep mode of commonly using interference unit.The conventional interference unit with frequency sweep mode is generally the mode of employing order frequency sweep, such as frequency order increasing or decreasing, therefore in the utility model embodiment, frequency hopping table is set to frequency and increases and decreases the order hocketing, and the frequency sweep that can effectively avoid interference like this device is disturbed.In the present embodiment, the frequency hopping table frequency hop sequence of the first variable ratio frequency changer radio-frequency (RF) receiving and transmission module 12 and the second variable ratio frequency changer radio-frequency (RF) receiving and transmission module 22 is set to 433.0MHz, 434.7MHz, 431.3MHz, frequency across frequency amplitude, be not less than 1.7MHz, and adopt and first increase the frequency-hopping mode subtracting afterwards, the interference that can effectively resist single-frequency interference unit, double frequency interference unit and frequency sweep mode interference unit.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
