Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Fig. 1 is a schematic diagram of the present utility model.
As shown in Figure 1, discharge and recharge automatic control equipment, comprise high frequency electric source charging module CV1 and external battery GE1, be connected with data acquisition microprocessor-based monitoring device and charge-discharge circuit, can realize the online of battery discharged and recharged at the two poles of the earth of described high frequency electric source charging module CV1 and battery GE1.
The high frequency electric source charging module CV1 that adopts in the present embodiment, its model is RSD3000.
The data acquisition microprocessor-based monitoring device that adopts in the present embodiment is applicant's commercially available prod, and its model is MC6000.This device integrates supervision, monitoring, control, fault alarm, data printing, telecommunication.More perfect self-checking function and power-down protection are arranged; Affair alarm, actuation of an alarm threshold values etc. can redefine according to actual needs, make up; Also can get in touch, also can realize telecommunication and four distant (remote signalling, remote measurement, remote control, remote regulating) by the remote monitoring software of modem and shared telephone network and my company by communication protocol and the on-the-spot host computer realization data communication selecting to wear at random.
As shown in Figure 1, be connected in series diode 1V1, diode V1 between the positive pole of high frequency electric source charging module CV1 and the positive pole of battery GE1, the negative pole of these two diodes links to each other, and its positive pole is connected with the positive pole of battery GE1 and the positive pole of high frequency electric source charging module CV1 respectively; The two poles of the earth of diode V1 are parallel with contactor KM1; Battery GE1 positive and negative electrode is parallel with data acquisition microprocessor-based monitoring device, voltmeter 1PV, discharge resistance Rfz and contactor KM2; High frequency electric source charging module CV1 is in parallel with battery GE1; The two ends of the positive and negative electrode of battery GE1 and discharge resistance Rfz are serially connected with fuse FU1, FU2 respectively; The positive and negative electrode of battery GE1 is connected to air switch QF, and its negative pole is connected to shunt FL1 and the ammeter 1PA in parallel with shunt FL1.
When discharging and recharging the automatic control equipment operation, the data acquisition microprocessor-based monitoring device sends instruction, and charging contactor KM1 and disconnection discharge contactor KM2 close.High frequency electric source charging module CV1 carries out floating charge through isolating diode 1V1, charging contactor KM1, air switch QF and shunt FL1 to battery GE1.The data acquisition microprocessor-based monitoring device is by the charging/discharging voltage and the electric current of fuse FU1, FU2, ammeter 1PA and voltmeter 1PV monitoring battery.
When battery discharge, the data acquisition microprocessor-based monitoring device sends instruction, closes and discharges contactor KM2 and disconnect charging contactor KM1, and battery GE1 discharges to discharge resistance Rfz through air switch QF, shunt FL1, fuse FU2 and discharge contactor KM2.Because cell voltage is lower than the voltage of high frequency electric source charging module CV1 during battery GE1 discharge, charging contactor KM1 disconnects, and diode V1 oppositely ends, so high frequency electric source charging module CV1 can not discharge to discharge resistance Rfz.
When cell voltage is put into the microcomputer set point, the data acquisition microprocessor-based monitoring device sends instruction, disconnect the discharge contactor KM2 and the charging contactor KM1 that closes, high frequency electric source charging module CV1 changes over to and all fills state to battery GE1 charging, and the microprocessor-based monitoring device of data acquisition simultaneously sends an end-of-discharge signal to the backstage.
When charging current less than 1A time remaining 3 hours or bulk charge time remaining after 22 hours, high frequency electric source charging module CV1 changes floating charge state over to, the micro computer monitoring of data acquisition simultaneously sends one and all fills the state end signal to the backstage.
If be in operation, exchange to have a power failure or the high frequency electric source charging module unusual, the data acquisition microprocessor-based monitoring device will send alarm signal, make that to discharge and recharge automatic control equipment out of service, this moment, battery was through air switch QF, diode V1 powering load.
