Background technology
In the storage yard operation of loading and unloading, generally adopt computer system to send work data, realize commander automatically to tyre crane.The power supply that receives the terminal computer of industry data in the tyre crane drivers' cab directly adopts the storage battery of tyre crane master Diesel engine; when Main Engine Start or the switching of primary/secondary engine; the storage battery transient large current discharge; cause voltage instantaneous to descend; drop to 15～17V from 24V; after terminal computer detects voltage and descends, enter the self-protection program and shut down.Therefore, the driver must be restarted terminal computer, lands operating system again, has wasted the activity duration, may miss the receipts work data in restarting process, causes operation to pause, and in addition, frequent starting is also unfavorable to terminal computer itself.This problem also often takes place in the liquid crystal display television (LCD TV) power system of Tour Bus.These reasons cause the driver to be reluctant to close sustainer, have increased unnecessary oil consumption and toxic emission.
Summary of the invention
The purpose of this utility model is to provide a kind of compensation arrangement of airborne appliances power source, and terminal computer voltage descended and the technical problem of shutdown automatically when the compensation arrangement of described this airborne appliances power source will solve Main Engine Start in the prior art.
The compensation arrangement of this airborne appliances power source of the present utility model is by one first diode, one second diode, a resistor and a capacitor constitute, wherein, described first diode and resistor are connected in parallel, after being connected in parallel, first diode and resistor be connected between the end of the negative pole of second diode and capacitor, the positive pole of second diode and the other end of capacitor are connected respectively to the two ends of a storage battery interface, the described other end of capacitor and the negative pole of second diode are connected respectively on the positive terminal and negative pole end of a dc output end mouth, and the negative pole of first diode links to each other with the negative pole of second diode.
Further, the two ends of described capacitor are connected with the capacitor of an above number.
Further, described capacitor all is encapsulated in the housing.
Operation principle of the present utility model is: be approximately 3s the start-up time of sustainer, battery recovery approximately needs 3s to primary voltage.The two ends of storage battery interface link to each other with the both positive and negative polarity of storage battery, directly pass through the dc output end mouth to airborne electric power supply, simultaneously, with electrical power storage in capacitor, when Main Engine Start or switching, capacitor is to dc output end confession electricity, and airborne electrical equipment continuous firing is kept in the voltage drop in the compensation 3s.Simultaneously, the capacitor group is encapsulated, can make it satisfy industrial service conditions such as vibrations, heat radiation.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model is provided with capacitor with store electrical energy in the DC power-supply circuit of airborne electrical equipment, and between capacitor and storage battery interface, be provided with diode, with realization capacitor is charged, the effect of discharging and recharging by capacitor constitutes voltage compensating circuit, when Main Engine Start or switching, can keep terminal computer or TV electrical equipment operate as normal.
Description of drawings
Fig. 1 is the structural representation of the circuit in the compensation arrangement of airborne appliances power source of the present utility model.
Embodiment
Embodiment 1:
As shown in Figure 1, the compensation arrangement of airborne appliances power source of the present utility model is by one first diode D1, one second diode D2, a resistor R and a capacitor C constitute, wherein, described first diode D1 and resistor R are connected in parallel, after being connected in parallel, the first diode D1 and resistor R be connected between the end of the negative pole of the second diode D2 and capacitor C, the other end of the positive pole of the second diode D2 and capacitor C is connected respectively to the two ends of a storage battery interface J1, the described other end of capacitor C and the negative pole of the second diode D2 are connected respectively on the positive terminal and negative pole end of a dc output end mouth J2, and the negative pole of the first diode D1 links to each other with the negative pole of the second diode D2.
Further, the two ends of described capacitor C are connected with the capacitor of an above number.
Further, described capacitor all is encapsulated in the housing.
Operation principle of the present utility model is: be approximately 3s the start-up time of sustainer, battery recovery approximately needs 3s to primary voltage.The two ends of storage battery interface J1 link to each other with the both positive and negative polarity of storage battery, directly pass through dc output end mouth J2 to airborne electric power supply, simultaneously, with electrical power storage in capacitor C, when Main Engine Start or switching, capacitor C is to dc output end mouth J2 power supply, and airborne electrical equipment continuous firing is kept in the voltage drop in the compensation 3s.Simultaneously, the capacitor group is encapsulated, can make it satisfy industrial service conditions such as vibrations, heat radiation.
In a preferred embodiment of the present utility model, the driver initiatively carries out primary/secondary engine when switching, and can save fuel oil; Simultaneously, reduce the damage of terminal appliance, saved certain maintenance cost.Energy-saving effect is estimated: suppose, a tyre crane accumulative total diel, sustainer is in holding state and time of not carrying out operation is 2 hours, and just can obtaining a chaptrel according to these data of the unloaded oil consumption 12L/h of sustainer so, to hang circadian fuel-economizing amount be 12 * 2=24L.If hang 80 calculating with the wheel of on average turning out for work every day, the fuel-economizing amount in 1 year is 24 * 80 * 365=700800L so.Amount to RMB 700800 * 5=3504000 unit.And the power supply compensation arrangement cost of exploitation just can save one by contrast greatly than paying wages only about 200 yuan every.Electrical phenomena also can appear jumping in the LCD TV on some Tour Buses when engine start, can use this device to solve equally.
