用ＰＩＣ１６Ｆ５１０单片机，实现按键调光程序。按键按一下为强光，按两下为工作光，工作光电流为强光的１／２，按３下为频闪，按４下为关机。且程序设定低电压报警功能，当外部供电不足９.９Ｖ时会闪烁１０次，低于８.４Ｖ时关机

说明：  本课题的针对小型水面无人艇的定位问题，确定无人艇的基本结构、尺寸和外观，进而设计控制系统，完成硬件选型，数据连接和传输方法，建立无人艇数学模型并确定一种智能控制方案，(This topic for small water unmanned boat location problem, the basic structure of unmanned craft, the size and appearance, and design of control system, complete the hardware selection, data connection and transmission method, to establish the mathematical model and determine an unmanned craft intelligent control scheme,)

自营店增加查看缴款记录功能，可以查看门店缴款。 记录数据，门店只能查看自己的缴款记录。 使用同价调拨和变价调拨可以产生相应的GSP报表，即做完同价调拨和变价调拨，可以到对应报表中调用同价调拨单和同价调拨单生成GSP报表。 增加“盘点数量为零商品显示”功能，并增加对盘点时有改动商品的颜色标注，便于对有盘点改动商品的进行跟踪，并且可以在盘点过程中添加电脑中没有的库存商品（自动盘营盘亏中）。 库存盘点时增加“产地”、“备注”和“生产厂家”字段（自动盘盈盘亏）。-payment record increase View function can check stores contributions. Records data, stores can only check their payment record. Using the same price allocation and price changes can have a corresponding allocation of the GSP statements, the same price that is done allocation and price variable allocation, statements corresponding to the call to allocate the same price and with the price of single-generation GPS allocation statements. Increase the "zero inventory quantity of goods shows that the" function, and increase the inventory of goods has changed the color tagging, facilitate inventory changes to a commodity tracking, and inventory in the process of adding a computer without the stock (automatic disk business inventory

牛顿－拉夫逊法潮流计算 基本步骤： 　　（1）形成节点导纳矩阵 　　（2）将各节点电压设初值U， 　　（3）将节点初值代入相关求式，求出修正方程式的常数项向量 　　（4）将节点电压初值代入求式，求出雅可比矩阵元素 　　（5）求解修正方程，求修正向量 　　（6）求取节点电压的新值 　　（7）检查是否收敛，如不收敛，则以各节点电压的新值作为初值自第3步重新开始进行狭义次迭代，否则转入下一步 　　（8）计算支路功率分布，PV节点无功功率和平衡节点柱入功率。(Newton-Raphson method flow calculation basic steps : (1) formation of nodal admittance matrix (2) to set up the initial node voltage U, (3) the initial node-generation-related demand. calculated that the constant term formula Vector (4) nodes will be incorporated into the initial voltage-seeking, calculated Jacobian matrix elements (5) solving that equation, seek to amend the vector (6) to strike a new node voltage value (7) to check whether convergence, if not restrained. concentrated in the nodes of the new voltage as the initial value since the first three steps to re-start the narrow iterations. Otherwise, turn into the next (8) Calculation branch power distribution, PV nodes reactive power and balance-node into power.)
