As shown in Figure 1, the utility model embodiment provides a kind of battery data acquisition device, can be applicable in the row tail system of train.This battery data acquisition device comprises data acquisition unit, universal asynchronous receiving-transmitting transmitter (Universal Asynchronous Receiver/Transmitter is called for short UART), multiple input end and an output terminal.One end of data acquisition unit connects output terminal, and the other end connects UART.Each input end is connected by a level translator with between UART.
As a preferred version, each input end is RS-232 data-interface, so that each input end is connected with charger.Meanwhile, output terminal is also RS-232 data-interface, so that can be connected with industrial computer.
Further, be provided with isolator between each input end and level translator, and be also provided with isolator between output terminal and data acquisition unit.Isolator is used for carrying out Phototube Coupling between battery data acquisition device and charger (or industrial computer), avoids on-the-spot bad electromagnetic environment to produce electromagnetic interference (EMI) to battery data acquisition device.
One-way transmission for the signal in the isolator of Phototube Coupling, input end and output terminal fully achieve electrical isolation, output signal without impact, mainly has that antijamming capability is strong on input end, working stability, contactless, long service life, transfer efficiency advantages of higher.Isolator is usually amplified three parts formed by the transmitting of light, the reception of light, signal.The electric signal of input drives light emitting diode (Light-Emitting Diode is called for short LED), makes it the light sending certain wavelength, is received and produce photocurrent by photo-detector, then export after amplifying further.This completes electricity---light---electricity conversion, thus play input, output, isolate effect.Due to isolator input, export between isolate mutually, electric signal transmission has the features such as one-way, and has good electrical isolation capabilities and antijamming capability.Again because the input end of isolator belongs to the low resistance element of current mode work, thus there is very strong common mode inhibition capacity.Therefore, isolator greatly can improve signal to noise ratio (S/N ratio) as terminal isolated component in transmission information, and increases the reliability of computer operation.
