1.市場概述 Market Overview

隨著汽車智能化、電動化的發(fā)展趨勢，電動汽車將成為未來汽車的主流，由此帶來電動汽車充電樁的發(fā)展。充電樁中需要安裝電表，來測量充電電壓和充電電流以及統(tǒng)計充電電量，并通過RS485總線與控制模塊進行通信。

With the developmentof intelligent and electric vehicles, electric vehicles will become the mainstream of future vehicles, thus bringing the development of charging piles for electric vehicles.An electricity meter should be installed in the charging pile to measure the charging voltage and current as well as count the charging electricity, and communicate with the control module through RS485 .

2.DJSF1352直流電測儀表介紹 DJSF1352 DC Power Meter Introduction

DJSF1352-RN導(dǎo)軌式直流電能表帶有雙路直流輸入，主要針對直流充電樁應(yīng)用場合而設(shè)計，該系列儀表可測量直流系統(tǒng)中的電壓、電流、功率以及正反向電能等。在實際使用現(xiàn)場，即可計量總電能，又可計量規(guī)定時間段內(nèi)的電能。檢測的結(jié)果既可用于本地顯示，又能與工控設(shè)備、計算機連接，組成測控系統(tǒng)。儀表可具有紅外通訊接口和RS-485通訊接口，同時支持Modbus-RTU協(xié)議；可帶繼電器報警輸出和開關(guān)量輸入功能；根據(jù)不同要求，通過儀表面板按鍵，對變比、報警、通訊進行設(shè)置；具有開關(guān)量事件記錄（Modbus協(xié)議）電壓電流功率大值、小值記錄功能。

DJSF1352 has double DC input channels, mainly designed for DC charging piles, solar , this series of meters can measure the voltage, current, power and forward and reverse energy and so on in the DC system.The actual use of the site, you can measure the total power, but also measure the energy within a specified period of time. The test results can be used for local display, but also with industrial control equipment, computers to form a measurement and control system.

The meter can have infrared communication interface and RS-485 communication interface, and

supports Modbus-RTU protocol .The meter can have relay alarm output and digital input function;You can set the ratio, alarm, and communication through the meter panel keys according to different requirements.The meter can have event recording of switch (Modbus protocol), maximum and minimum value recording function of voltage and current power.
