摘要 X線機蓄電池充電系統(tǒng)是X線機電力推進系統(tǒng)極為重要的組成部分,關(guān)乎X線機的動力性能，穩(wěn)定性能和安全能力。而這些都與X線機蓄電池充電控制系統(tǒng)密切相關(guān),如何設(shè)計出可靠、安全的充電控制系統(tǒng)使之能夠最大程度地延長蓄電池的使用時間。增加X線機的可持續(xù)能力一直是X線機蓄電池充電系統(tǒng)研究的主要內(nèi)容之一。
目前，我國的X光機供電系統(tǒng)有很多是引用國外現(xiàn)成電路生產(chǎn)的。其中有些電路，其技術(shù)已經(jīng)比較落后，有些電路的器件也已不再生產(chǎn)，生產(chǎn)廠家急需對這些電路進行技術(shù)改進和升級，對其中所使用的器件需要用現(xiàn)有器件進行替代，因此，需要對這些電路進行解剖分析，理清其工作原理和器件的作用，為設(shè)備的改進升級和器件的替換提供理論支持。為完成國內(nèi)X線機的更新?lián)Q代提供了保障。
本文首先闡述了蓄電池和X線機的發(fā)展歷程和相關(guān)知識以及蓄電池在X線機中的應(yīng)用。對X線機中蓄電池的性能進行了深刻的研究，分析了X線機對蓄電池的一些要求。第二章中闡述了各種蓄電池充電方法及其各自的優(yōu)缺點。第三章著重的闡述了MUX-99充電電路，分析了其中各個模塊的具體電路。例如：可控硅觸發(fā)電路，啟動逆變電路，充電檢測電路，計時器、起動機震蕩電路，控制板接口電路等，尤其對電路中的器件所起的作用進行了分析。
在理論分析的基礎(chǔ)上，應(yīng)用 Multisim仿真軟件和Protel 99 SE對充電控制系統(tǒng)進行了建模仿真，并針對實際系統(tǒng)的幾種典型工況進行了仿真,給出了仿真波形及理論分析。
對X線機充電系統(tǒng)進行了深刻的研究，結(jié)果表明這一充電電路具有很大的發(fā)展空間。

X-ray machine charging circuit analysis

Abstract X-ray machine battery charging system is an extremely important part of the X-ray machine electric propulsion system, dynamic performance, stability and security capabilities in relation to the X-ray machine. The X-ray machine battery charging control system is closely related to how to design a reliable and safe charging control system so that it can maximize the battery usage time. The sustainability of the X-ray machine increasing has been one of the main X-ray machine battery charging systems research.
 At present, the power supply system of Chinese X-ray machine is a reference to a lot of foreign-shelf circuit production.Some circuit technology is relatively backward, the device has also been produced no longer , the manufacturer of these circuits urgent need to technical improvements and upgrades, for which the device needs to be replaced by the use of existing devices, therefore, the need for these circuit anatomical analysis, clarify the role of the working principle and devices to provide theoretical support for the replacement equipment upgrades and improvements . To complete the upgrading of domestic X-ray machine to provide a guarantee.
    This paper first describes the development process and knowledge of the battery and the X-ray machine as well as the application of a battery in X-ray machine. X-ray machine in the battery performance was profound study, analyzing the X-ray machine on some requirements of the battery. Chapter II describes the various battery charging methods and their respective advantages and disadvantages. The third chapter describes the MUX-99 charging circuit, analyzing the specific circuit of each module. For example: SCR trigger circuit, to start the inverter circuit, a charge detection circuit, a timer, starter oscillator circuit, the control panel interface circuit, the circuit in particular the role of the device is analyzed.
Based on the theoretical analysis, The thesis has modeled most parts of the battery charger system by using system simulation software Multisim simulation and Protel 99 SE, and make simulation waveform analysis against the typical working conditions.

Charging system on the X-ray machine had a profound study, the results show that the charging circuit has much development.

Key words Mobile X-ray machine charging circuit charging method
