Wherein, described microcontroller and accessory circuit unit, also for the voltage of monitor vehicle battery, and according to the voltage swing detecting, emergency cut-off Vehicular battery
The utility model has the advantage of, when meeting hazardous materials transportation vehicle associated safety requirement function, protected to greatest extent the electronic equipment of vehicle when emergency cut-off battery, not to be subject to accidental damage.Adopting the intelligent battery switch application of the utility model principle is to vehicle electric element system important safeguard measure in hazardous materials transportation vehicle.
Accompanying drawing explanation
Fig. 1 is systematic schematic diagram of the present utility model
Embodiment
1 be described in further detail by reference to the accompanying drawings.
In Fig. 1, for the intelligent battery switch 2 of hazardous materials transportation vehicle mainly by solid-state relay 3,4, high power solid state relay 6, microcontroller and accessory circuit 7 thereof form.When vehicle is normally worked.30 and 87 contacts that Vehicular battery 5 passes through high power solid state relay 6 are to vehicle electric element load supplying.Vehicular battery 5 is 30 contact power supplies of solid-state relay 3 simultaneously, 85,86 contacts of the controller co-controlling solid-state relay 3 of ignition switch 15 lines and intelligent battery switch.Solid-state relay 3 is subject to ignition switch 15 line traffic control conductings 30 and 87 contacts, for the important electric-control system of vehicle provides 15 line power supplys.Solid-state relay 3 also plays the effect of central 15 relays simultaneously.30 and 87a contact of solid-state relay 4 connects the charging circuit 10 and generator 1 of ignition switch 15 lines and generator, for generator provides exciting current and indicates charged state.
When the vehicle of peril of transportation product is in an emergency (as fire, leakage, traffic hazard), driver opens in pilothouse or the EmS 9 of installing on chassis, 30 and 87a contact that first the microcontroller 7 of intelligent battery switch inside controls solid-state relay 4 disconnect, cut off the exciting current of generator, generator is quit work, and connect alarm buzzer 8.Generator quit work after 5 seconds, and 30 and 87 contacts that microcontroller 7 is controlled solid-state relay 3 disconnect, thereby made 15 load line power-off of output.First generator quits work and can avoid battery to cut out the load shock bringing, and the time delays of 5 seconds can make vehicle electric element load fully absorb the reverse impact of generator electromagnetism perception electromotive force.That 15 load line power-off make is engine electric-controlled, wheel box is automatically controlled enters lower power mode, and engine, variator are shut down.After 15 load line power-off, microcontroller 7 carries out after the time delay of 9 seconds again, controls high power solid state relay 6 and thoroughly cuts off the power supplys of Vehicular batteries 5.The time delay of 9 seconds can guarantee the electric-control system storage data that engine etc. is important, and makes after engine shutdown by inertial states to stopping completely.Intelligent battery switch cuts off after the power supply of battery 5 completely, alarm buzzer 8 stop alarms.Because some electric equipments of vehicle need to also be powered by battery when the emergency circumstance.As based on security consideration, even when emergency cut-off battery, also need the stand by lamp work of glistening.Therefore intelligent battery switch 2 leaves normal electrical load interfaces, is used to this type of electric equipment power supply.
For the intelligent battery switch 2 of hazardous materials transportation vehicle outside possessing above-mentioned functions, the also integrated function of voltage monitoring of common intelligent battery switch.The voltage of microcontroller 7 monitoring batteries 5.When continuous 60 seconds of cell voltage is during lower than 22.8V, intelligent battery switch 2 cuts out the operation of battery.This operation is consistent with the operation being caused by EmS 9 under the emergency circumstance.This function can guarantee to shut down for a long time electricity consumption and forget close battery hand switch in the situation that Vehicular battery possesses basic starting electric weight driver.
