Description
Technical field
The present invention relates to the mobile vehicle communication for being widely used in emergency communication more particularly to storage battery low-voltage detections and protection
The technical field of device.
Background technology
China region is wide, flow of the people is big, and occasion, accident often occur, in order to ensure communication capacity, therefore
It needs to build emergency communication system, mainly BTS antenna equipments is loaded in mobile communication car, for the people because of great work
Dynamic aggregation extensively (such as competitive sports, large-scale outdoor party) or accident cause somewhere field communication to interrupt, and (such as somewhere is moved
Dynamic antenna control tower damage) etc. unconventional situation.
Mobile vehicle communication provides wireless communication coverage by cell on wheels equipment, for emergent scene.Its mainly include chassis,
The compositions such as power station cabin, equipment compartment and elevating lever cabin.For mobile vehicle communication when organizing work, automatic control equipment passes through storage first
Battery powered is opened, and controls the expansion of the equipment such as elevating lever, antenna for base station, microwave antenna, lightning rod, hatchcover, while starting hair
Motor is powered to full vehicle, and generator is charged a battery by charger.
When mobile vehicle communication starts to spread out, if battery tension is too low, when power switch closes a floodgate, automatic control equipment
It cannot normally start, battery tension can not be detected, also without any indicating fault, it is what to cause operating personnel that can not judge
Failure.Automatic control equipment cannot normally start, and also can not just start generator, but system appoints right battery consumption electric energy, leads
Battery tension is caused further to decline, accumulator is damaged due to over-discharge under extreme case.
Invention content
It is an object of the present invention to provide the case where a kind of too low in battery tension, automatic control equipment cannot normally start
Under, by relay test battery tension, and provide the mobile vehicle communication storage battery low-voltage detection of accumulator low-voltage instruction
Protective device and working method.
Mobile vehicle communication storage battery low-voltage detects protective device, and accumulator connect with power switch, power switch respectively with
Positive power line is connected with negative power line, and coil, normally-closed contact, automatic control are connected in parallel between the positive power line and negative power line
Control equipment；It connects on positive power line between the normally-closed contact and automatic control equipment normally opened contact；The normally-closed contact with
Acoustic-optic alarm is connected in series with.
Mobile vehicle communication storage battery low-voltage based on the present invention detects the working method of protective device, and communication truck needs to be unfolded
When, storage battery power supply, power switch closes a floodgate, if battery tension is too low, relay is failure to actuate, and normally-closed contact is closed, normally opened
Contact is opened, and warning device is lighted, and instruction battery tension is low；If accumulator be equal to or higher than operating voltage, the actuating of relay,
Normally-closed contact is opened, and normally opened contact is closed, and warning device does not work, storage battery power supply, automatic control equipment normal work, and can be certainly
The dynamic generator that starts charges a battery.
The vehicle-mounted nominal battery voltage for equipment control of mobile vehicle communication of the present invention is 24V, accumulator output electricity
There is power switch in road, uses a coil nominal voltage for the DC relay of 24V, at least one normally opened contact of relay
With a normally-closed contact, coil is connected on the positive-negative power line after power switch.Relay normally closed contact, a resistance and
After the series connection of one acoustic-optic alarm, it is connected on the positive-negative power line after power switch, is gone here and there on positive power line thereafter
Enter relay normally open contact, then to the mobile unit power supply for including automatic control equipment etc..Coil nominal voltage is the straight of 24V
Current relay, the minimum sealing voltage of coil are the 75% of nominal voltage, that is, 18V.
When the communication truck expansion of the present invention, storage battery power supply power switch closes a floodgate, if battery tension is less than 18V, after
Electric appliance is failure to actuate, and normally-closed contact is still closed, and normally opened contact is still opened, and acoustic-optic alarm is lighted, and indicates battery tension
It is low, and since normally opened contact is opened, there is no powering to follow-up equipment, acoustic-optic alarm power consumption is very small, can provide
In the case that operating personnel's accumulator low-voltage indicates, maximum possible avoids accumulator over-discharge and damages；If accumulator
Voltage is equal to or higher than 18V, the actuating of relay, and normally-closed contact is opened, and normally opened contact is closed, and acoustic-optic alarm point does not work, and is stored
Battery is powered to mobile unit, automatic control equipment normal work, and can be started generator automatically and be charged a battery.
If Vehicular accumulator cell nominal voltage is 12V, 12V DC relay can be used to realize.If vehicular electricity storage
Pond nominal voltage is more than 24V, then 24V DC relays still may be used, but its coil will concatenate a resistance.
Above-mentioned acoustic-optic alarm can also change other sound, light or acoustic-optic alarm into, be used to indicate low-voltage, but answer
The warning device for using low-power consumption as possible, avoids accumulator over-discharge.
The present invention can simply and reliablely detect accumulator low-voltage and provide low-voltage instruction, and accumulator is avoided excessively to put
Electricity protects accumulator.
