基于这些Budget aims/goals The current budget aim is to produce a solution while staying well under our project prototyping budget of $350. We aim to keep our budget below 50% of the $350, however this will only be achievable in the development phase because of savings of borrowed items from Shoalhaven Water. Final costings will be dependent on housing construction and will be decided after further discussion with Shoalhaven Water. Budget Estimate Most hardware components in the design are finalised for both the power system and housing, compiled in a full list, sourced, and budgeted. Changes to Previous Estimate: Updated the selected battery from the 6000mAh LIPO ($31) to 2x parallel 18650 2600mAh with battery holders ($46 + $7). Updated solar power manager and separate solar panel cost ($8 and $12) to a combined solar panel and power manager ($50) This solar power manager added an optional 5v input and removed the need for the voltage regulator ($5). Added two Stainless Steel U Bolts ($10) and O-ring gasket material ($5) for housing. The estimated total was updated from $273 to $340. Project Costing Hardware The supplied components include the mDot LoRaWAN device ($74), the voltage pulse reed switch ($93) (water meter and standpipe are already used/in field). The device cost will only consider the hardware involved. It will utilise the Shoalhaven Water pre-existing LoRaWAN network as well as their backend infrastructure for data storage and analysis which are additional costs that will not be accounted for in the budget of this project. The estimated cost of the device hardware per unit is $340. The full list of device hardware expenses is detailed below in table VIII. For the project prototype, Shoalhaven Water are supplying the LoRaWAN mDot, voltage pulse reed switch, standpipe and water meter, making the actual hardware expenses during the project just $173. This means that our design is $177 below our required project budget.

根据我们的预算目标,我们的当前预算目标是在项目原型预算的350美元以下的情况下制定解决方案。我们的目标是将我们的预算保持在350美元的50%以下,但由于从Shoalhaven Water借用物品的节省,在开发阶段才能实现。最终成本将取决于住房建设,并将在与Shoalhaven Water进一步讨论后决定。
预算估计中,设计中的大多数硬件组件已经确定,包括电源系统和外壳,在一个完整的清单中,预算已经编制好。与之前的估算相比,我们做出了以下修改:
- 将选定的6000mAh LIPO电池($31)更新为2个并联的18650 2600mAh电池和电池座($46 + $7)。
- 将太阳能电源管理器和独立的太阳能电池板费用($8和$12)更新为组合太阳能电池板和电源管理器($50)。此太阳能电源管理器增加了可选的5v输入,并消除了需要电压调节器($5)。
- 为外壳添加了两个不锈钢U型螺栓($10)和O形密封垫材料($5)。
预计总成本已从273美元更新为340美元。
项目成本包括硬件和软件两部分。在硬件部分,Shoalhaven Water提供了LoRaWAN mDot、电压脉冲簧片开关、立管和水表,实际硬件成本只有173美元。这意味着我们的设计比所需的项目预算低177美元。值得注意的是,Shoalhaven Water的LoRaWAN网络和后端基础设施的数据存储和分析等附加成本不计入本项目的预算。

There is no getter for property named 'budget_id' in 'class com.cy.business.budget.domain.BudgetAdjust'
这个错误提示是说在 `com.cy.business.budget.domain.BudgetAdjust` 类中,没有名为 `budget_id` 的属性的 getter 方法。可能是在代码中使用了 `budget_id` 属性,但是没有在类中定义这个属性或者没有定义相应的 getter 方法。你需要检查一下 `BudgetAdjust` 类的定义,并且确认是否存在 `budget_id` 属性,以及是否有对应的 getter 方法。如果没有,可以在类中添加相应的定义。
np.random.normal(0, noise_param / budget, data[i].shape)
这段代码使用了 NumPy 库的 random 模块中的 normal 函数,用于生成服从正态分布的随机数。其中,0 表示正态分布的均值,noise_param / budget 表示正态分布的标准差,data[i].shape 表示生成的随机数的形状与输入数据 data[i] 的形状相同。这段代码的作用是为输入数据添加服从正态分布的噪声,其中 noise_param 和 budget 是控制噪声大小的参数。
