Abstract

The utility model relates to an alarm for the speed-mileage display and the state prompt of a bicycle, which adopts a microcontroller. The utility model is composed of the microcontroller MCU (1), a display (8), a speed sensor (7), an electricity-loss data preserving circuit (6), a keyboard (5), a voice prompt alarm circuit (4), a mercury switch block (2) and a sound organ (3). When the utility model is used, a switching signal of a Hall component is collected and processed, and the Hall component is installed at the vicinity of a bicycle wheel; thus, the running speed and the mileage of the bicycle can be displayed; a switching signal of a state prompting alarm of the bicycle is collected, so the running state, the quiescence state, the falling-down state, the stolen state, the broken state, the disassembled state and other states of the bicycle can be judged; thereby, the anti-theft alarm and the voice prompt of humanization of the bicycle are realized.

Description

Bicycle intelligent display annunciator

The utility model relates to a kind of bicycle speed mileage of microcontroller MCU that adopts and shows and bicycle condition prompting annunciator, it is by to being loaded on collection, the processing of near the hall device on-off signal the bicycle quick, realize the demonstration of bicycle running speed and mileage, and by to being loaded on the on-off signal collection of the condition prompting annunciator on the bicycle, judge the bicycle state, realize bicycle anti-theft alarm and voice suggestion.

The existing bicycle of China is only installed common lock, equal installation rate mileage telltales not, therefore driving person does not know own riding speed and mileage, and bicycle theft-prevention poor performance, lockset is very easily destroyed, and the stolen nothing to be surprised at of bicycle has influenced luxury car market, this device is used with common lock, will improve the bicycle theft-prevention performance greatly.

This device constitutes bicycle condition prompting annunciator by microcontroller MCU, telltale, dead electricity data preservation circuit, keyboard, voice prompt alarm circuit, mercury switch group; In addition, tachogen and cooperate microcontroller, telltale to form the bicycle speed mileage to show.This device has functional modules such as speed, mileage, Password Management, supervision, study, and it has advantages such as the simple cost of circuit is low.

The bicycle status information is mainly gathered by bicycle condition prompting annunciator, and the dynamic and static status data that will collect send, and MCU screens, processing, can realize bicycle anti-theft alarm and state voice suggestion.For example when bicycle is stolen, report " catch a thief, catch a thief "; When bicycle can be reported " thanks " or the like voice suggestion from the recovering state that falls down to erectility.This device has learning functionality, it is this device of mercury switch group break-make information typing with certain location state or state of kinematic motion under the learning state, and with the voice suggestion of this ad-hoc location state or state of kinematic motion or report to the police corresponding, thereby make bicycle have the prompt functions of hommization.Should " bicycle condition prompting annunciator " also can be used for other occasions, for example: be used to follow the transportation of valuable goods, this device will be reported to the police or the voice suggestion user when being in particular state such as inclination, inversion or vibration in the portage.The bicycle theft-prevention function is by cipher control, and the user can change password at any time.It has pick-proof, anti-pound, anti-disassembling function.When broken string, long-time vibration appear, arbitrary fix screw unscrews or bicycle is not unblanked to be in walking states or walking states and failed to detect tach signal and all will report to the police.

Implementation method is as follows: this product tachogen can be made of hall device and supporting magnet steel thereof, magnet steel can be fixed on the front vehicle wheel wheel hub, hall device is loaded on the appropriate location of bicycle front fork, make magnet steel from hall device next door through out-of-date, hall device can move, MCU can calculate moving velocity by calculating the required time that whenever circles, and travelled distance then obtains by the counting to revolution.

The mercury switch group is made of a plurality of mercury switches, wherein each mercury switch adopts respectively to crouch and puts, tilts or uprightly place and different directions and angle are arranged, with raising information acquisition precision, and be fixed on the interior printed circuit board of casing, casing is horizontally fixed on the bicycle.When the appearance dismounting, when unscrewing the casing fix screw, corresponding normally closed interlock is opened, and then series connected normally closed interlock group opens circuit and reports to the police, or broken string, the long-time vibration occur, and situations such as swing are also all reported to the police.Need input correct password if withdraw from monitored state, every loom is all joined an administrator password, and the user can be provided with and revise user cipher arbitrarily.

This machine is by gathering mercury switch group on-off signal, judges that bicycle is in static, normal condition or be in by abnormal states such as prizing, pounded, stolen such as fall down or ride.Under monitored state, this machine is constantly gathered mercury switch group signal and acquired signal is stored among the RAM, then current state and previous state are compared, if it is constant, illustrate that bicycle remains static, and according to Changing Pattern judge vibration, the state of riding or the like, simultaneously also relatively with the on-off signal of current collection and " sample ", be used to judge that bicycle crouches state such as puts, upright, " sample " obtained by experiment, can comprise the break-make information of all or part of mercury switch that the mercury switch group should have under each section's state.

Embodiment can further specify with accompanying drawing: the utility model is preserved circuit (6), keyboard (5), voice alarm circuit (4), mercury switch group (2) formation by microcontroller MCU (1), telltale (8), tachogen (7), dead electricity data.Wherein, microcontroller MCU (1) adopts 89C51 to make master controller, by programming to 89C51, and various functions such as realization speed, mileage, Password Management, supervision.Tachogen adopts the Hall switch device, its supporting magnet steel is fixed on the front truck wheel hub with epoxy resin, the Hall switch device is fixed in the bicycle front fork appropriate location, bicycle quick turns over a circle, the hall device action once, because wheel diameter is known, therefore poor by calculating twice opening time, can calculate rotating speed; By calculating mileage to the wheel revolutions counting.

Each mercury switch in the mercury switch group all links to each other with the I/O port of MCU through 8D latch 374, bicycle each mercury switch under different conditions turns on and off state different combinations, and change along with state variation, after experiment sieving or study, useful combination is stored in 24C04 dead electricity data preserves in the circuit (4), its useful combination can be the combination of part or all of mercury switch on off mode, the establishment condition during as judgement bicycle state.

These facility have learning functionality, are the information that learning state is gathered is down screened, and get the combination of its mercury switch on off mode, compare with other bicycle state, if different promptly as useful combination preservation again.

This product phonological component adopts speech IC, and keyboard is established function key, numerical key and acknowledgement key.And adopting 4 LED (or LCD) telltale, power supply adopts sealed type lead acid battery.
