Abstract
Charge in batteries burglar alarm, be accumulator when outdoor charging, as long as unload wherein any one, charge in batteries electric wire (comprising power lead), the device that alarm will sound in indoor immediately.Its principle utilizes capacitor to lead to the characteristic exchanging stopping direct current, and series connection in the mains supply, gathers the weak voltage between capacitor (2) two-plate, amplifier (4) amplifies, after rectifier (3) rectification, transfer to relay (5) to control the break-make of hummer (6) circuit, reach alarm function.Current-limiting apparatus (11) uses and solve for preventing the alarm from connecting multiple charger overload the problem that shunt load steals accumulator.
Description
Technical field
Charge in batteries burglar alarm, be accumulator when outdoor charging, as long as unload wherein any one, charge in batteries electric wire (comprising power lead), the device that alarm will sound in indoor immediately.
Background technology
At present, the technology such as alarm adopts infrared induction, concussion contacts, image photoelectricity blocks that market is common, are applied to the fields such as auto alarm, home security, gas-monitoring.But electromobile battery charging is then linked in electric motor car by power lead to charge, and be all generally night outdoor charging, especially building user, also power lead will be pulled and charge downstairs.If utilize infrared remote control, there is dead angle, block and just can lose efficacy; If alarm is arranged on outdoor vehicle body, is also easily destroyed and lost efficacy, and being disturbed residents.So the burglar alarm effect that current electric motor car user uses is all not ideal enough, lose storage battery, lose the situation of electric motor car and occur repeatedly, car owner loses seriously.
?
Utility model content
Charge in batteries burglar alarm, comprise capacitor, amplifier, rectifier, restrictor, relay, hummer etc., it is characterized in that: utilize capacitor logical interchange stopping direct current characteristic, be serially connected in charger front end AC circuit, the weak voltage gathering capacitor two ends carries out amplification and rectification, rectification DC voltage supply relay switch out controls, cut off and closed buzzer warning, circuit output end install additional restrictor prevent overload from using and solve shunt load steal problem.
Accompanying drawing explanation
Fig. 1 is charge in batteries burglar alarm schematic diagram.
Embodiment
Charge in batteries burglar alarm is accessed 220 volts of power supplys, alarm is placed on indoor, then the electric wire that alarm is extended out link outdoor electric motor car charger on charge.As long as disconnected power down source, charger or connect any of battery cable, indoor alarm equipment just can pipe warning immediately.The effect of restrictor also can pipe when being overload warning, solves an alarm and utilizes shunt load to carry out the problem cracked to the overload hidden danger of multiple electric motor car charging and stealer.
Claims (4)
1. charge in batteries burglar alarm, comprise capacitor, amplifier, rectifier, restrictor, relay, hummer etc., it is characterized in that: utilize capacitor logical interchange stopping direct current characteristic, be serially connected in charger front end AC circuit, the weak voltage gathering capacitor two ends carries out amplification and rectification, rectification DC voltage supply relay switch out controls, cut off and closed buzzer warning, circuit output end install additional restrictor prevent overload from using and solve shunt load steal problem.
2. charge in batteries burglar alarm according to claim 1, is characterized in that: accumulator is in outdoor charging, and alarm is in indoor warning, and this design has disguise.
3. charge in batteries burglar alarm according to claim 1, it is characterized in that: the weak voltage gathering capacitor two ends, rectification amplify after worked by Control hummer, if charge current interruption or electric current reduce to can not pilot relay work time; buzzer warning.
4. charge in batteries burglar alarm according to claim 1, is characterized in that: restrictor current limliting should be a bit larger tham charging current, if increase charging load, buzzer warning.
