(2020.6.23to update)
1 Software and hardware environment for running the software
The software is divided into network version and stand-alone version.
1,Network version
It is also divided into Internet version and LAN version. The Internet version is suitable for anyone to use online at any place, and the LAN version is suitable for companies and units.
The Internet version of this software is suitable for a variety of mainstream browsers, preferably equivalent to IE10.0Above version. Computers, mobile phones, virtual machines and total stations can be operated and used online without installation or uninstallation. Large computer screen, easy to operate, recommended.
2,Stand-alone version
It is also divided into browser version and form version. Suitable for single computer, total station and virtual machine.
The use of virtual machines is mainly suitable for units and individuals with higher security level.
There are many types of total stations, and the data file format is not uniform. You can write a conversion program in high-level program language to convert it into the unified data file format of the software.
The software is currently ready to be released on the Internet, and other versions will not be released temporarily.
2 summary
《Total Station Arbitrary Network Survey(Referred to as arbitrary network)The software system regards the field fixed-point survey of total station as a network. The simplest network is a survey station traverse composed of two known points and one desired point, and the complex network is unlimited.
This software is suitable for the adjustment of horizontal control networks of the first, second, third, fourth and lower grades, including the adjustment of control networks with known conditions, the adjustment of rank defect networks, the adjustment of quasi-stable networks, robust estimation, ridge estimation, estimation, compensation projection deformation and gross error processing. At the same time, the adjustment calculation of triangular elevation network is also carried out. It can meet all kinds of intersections, wires, locks and nets(Including angle measuring network, side measuring network, corner measuring network, traverse network, etc),Typical graphics and some special and difficult work of measuring fixed points.
In addition to adjustment calculation, the software will automatically complete a lot of work. All the things that computers can do are left to computers to do, so as to reduce the user's labor burden and improve work efficiency.
Unified and concise observation data file format(Can be a text file or a Word table or an Excel table),No matter how complex the control network is, the data file format is uniform, which only contains the necessary observation data and known data, and does not require user calculation and statistical data.
This software allows mixed observation of any observation set with half observation set, one observation set and multiple observation sets at the same station, and also allows no observation in some directions within the observation set to meet the needs of fixed points with different accuracy.
With this software, the field work can be controlled and measured at the same time, and the field work that needs to be done at one station can be completed. It is not necessary to control first and then observe separately, so as to reduce repetitive work.
After the user submits the data file, the result can be obtained in about ten seconds under normal network conditions. After a series of calculation and processing, the system pushes various results web pages to users, combines pictures and text, and automatically generates various results reports. Users only need to browse, print, copy, and download. This software has good data confidentiality.
If there is gross error in observation, the software will detect the specific range of observation values that may carry gross error.
This software allows known points in the control network to be invisible to each other. Any dispersion between known conditions is allowed, that is, they are not adjacent to each other, independent of each other, independent of each other, etc.
In this software, the number of approximate estimates is 3. The maximum number of adjustment iterations is 20. The maximum absolute value of the iterative unknowns correction value is less than 0 in the field.0001mThe iteration is completed normally, otherwise a prompt will be given.
One of the display features of this software is to strive for high automation and intelligence of the working process.
This software is suitable for production, scientific research and teaching.
3 What users need to do
(1)Users only need to sort out the observation data files and strive for a successful submission.
(2)Users only need to master at least 2 independent plane observation conditions for each unknown point. This can be called basic observation conditions. However, the entire control network needs a certain number of redundant observation conditions to achieve the purpose of adjustment. For example, the intersection of an unknown point must have at least one redundant observation condition. The number of redundant observation conditions shall be appropriately determined according to the accuracy requirements of the control network, the requirements of technical documents, the actual use, the importance and other factors.
(3)Operation steps: set up → option →Submit data file → Browse Results(See the main page introduction and example video of peace and difference for various achievements)。
For the adjustment projects below the fourth grade, most of them can use the default settings. At this time, you only need to submit data files to get all the results.
(4)Error checking. Although the software can automatically detect a large number of errors and feed back to the user to modify the data file, the user should actively check and eliminate all errors in the data file and strive to submit successfully at one time. The automatic check of the software is used as the final supplementary check to help users find hidden errors.
4 Work that users don't need to care about
Except for the "work that users need to do", they are all work that users do not need to care about. For example, users do not need to care about how to calculate the coordinate elevation, the number, order, mutual relationship and quantity of triangles and points, edges and corners, the connection direction and order of traverse points, the type of network and the complexity of the network, etc. Background robot function of the software(artificial intelligence)These tasks will be completed automatically, but not limited to these tasks, which will not be listed here. In short, the software is responsible for handling the complex logic in the control network.
We are still making continuous efforts to make users work less and bear less and less burden. Create an easy and fast working environment for users.
5 application prospect
This software can be widely used in the survey points, adjustment calculation, deformation monitoring, etc. in the planning, survey, engineering design and construction stages. It can also be applied to other important fields. Able to locate distant targets(Distant refers to the farthest target observed with telescopic equipment)。This software system has potential applications. If the total station is used to work with GPS, the software system will play a greater and more important role.
In particular, the software can observe targets that are unreachable, difficult to reach, or costly to reach to obtain accurate coordinates and elevations. And it is more suitable for projects with other equipment for fixed-point, difficult network construction and high cost. More importantly, the software system realizes the high automation and intelligence of the work process, so as to greatly reduce the input of human resources and the labor intensity of staff.
For a specific large and medium-sized engineering project, if the work plan layout is properly designed by using this software system, the number of survey professionals can be greatly reduced, and the production tasks related to planning survey, design and long-term construction observation can be completed in a high speed and efficiency.
This software can solve problems that are difficult to solve with traditional methods. For example, there are huge obstacles or even intervisibility obstacles(Such as the separation of large rivers, the blocking of high mountains, etc)The target is accurately observed and located at the least cost.
This software system is not limited to the above applications.
This software is suitable for existing and future observation schemes.
The existing control network observation schemes include various existing intersections, various traverse networks, angle measuring networks, side measuring networks, side angle networks, various control networks and typical graphs, as well as various schemes mentioned in the overview. The future observation scheme is creative to solve some special technical problems. This is the characteristic of arbitrary network.
Some arbitrary networks may be complex in form, but it will shorten the actual working hours of staff, reduce labor intensity, and reduce production costs.
The purpose of constructing arbitrary network is to save time and effort, and also meet the overall accuracy and quality requirements. More complex arbitrary networks are often constructed in exchange for easier design and practical work, more cost saving and total resource consumption. Its complex logic is entrusted to the software system to complete analysis, judgment, data processing and push results to users. No matter how complex an arbitrary network is, the form of its observation data file is unified and concise. Users need to further understand the above in practical applications.
Because the arbitrary network is generated according to the will of people, it does not need to spend too much energy, but only needs to master the plane independent observation conditions for each unknown point, which is not less than 2, and at the same time meets the requirements specified in the technical documents(Such as the necessary number of observation sets, the objectives that must be observed, the requirements specified in the specifications, etc)Yes. In addition, for important engineering parts, in order to further improve the accuracy and reliability, several independent observation conditions that can be easily obtained can be appropriately added on the basis of the basic observation conditions. However, for general survey areas, it is sufficient to include a certain number of inspection conditions on the basis of basic observation conditions, such as multiple rear view traverse.
As for the easily obtained observation values, for example, it is easy to observe the direction of the target with obvious signs, and then record the readings after aiming at the target. Therefore, any target that is easy to aim at the observation direction should be observed as much as possible, because the direction observation is easy to obtain high-quality observation values, that is, precisely aim at the target and press the record key. As long as these goals can play a good control role, they can be fully utilized. However, for observation values that are difficult to obtain, it is generally not recommended to make redundant observations unless the basic observation conditions and technical document requirements are met. Adding redundant independent observation conditions should follow the principle of "easy first, then difficult". After the number of observation values obtained for the easily observed targets has met the requirements of control network accuracy and reliability, the targets with high observation costs will not be considered.
Adding independent observation conditions is obvious for improving the accuracy of the whole network, but too many redundant observations are a waste. You can test run the software several times during the work of the control network. By viewing the log file, you can understand the current work situation, grasp the work progress, and avoid excessive redundant observation, so as to avoid wasting personnel and resources.
6 The scope of instruments and equipment involved in the term "total station"
At present, the main measuring instrument for establishing angle and distance measurement control network and fixed points is total station. However, the "total station" referred to in this software is the unified name of such instruments and equipment. It mainly includes theodolite, distance measuring instrument, combined theodolite distance measuring instrument, total station and new angle measuring and distance measuring instruments and equipment in the future. All instruments and equipment with the function of angle measurement and distance measurement are applicable to the software system. The unified observation data files obtained by using these instruments and equipment can be submitted to the software system for the same processing.

《全站仪任意网测量》(简称任意网 )软件系统把全站仪外业定点测量统一看作网。最简单的网是由两个已知点和一个所求点构成的一测站支导线,复杂网无限制。
本软件适合一、二、三、四等以及五等以下各等级平面网平差处理,其中还包括附加已知条件的控制网平差、秩亏网平差、拟稳网平差、稳健估计、岭估计、概算、抵偿投影变形和粗差处理等。同时也进行三角高程平差计算和三角高程网平差计算。可以满足各种交会、导线、锁、网(包括测角网、测边网、边角网、导线网等)、典型图形以及一些特殊的和困难的测量定点工作。
除平差计算外,本软件还会自动完成大量工作内容。凡是计算机能做的事情都交给计算机去做,以尽力减轻用户劳动负担,提高工作效率。
具有统一简洁的观测数据文件格式(可以是文本文件或Word表格或Excel表格),而不论控制网有多复杂,数据文件格式都是统一的,其中只包含必须的观测数据和已知数据,不需要用户计算和统计的数据等。
本软件允许在同一设站上有半测回、一测回及多测回的任意测回混合观测,还允许测回内的一些方向不观测,以满足不同精度的定点需要。
利用本软件,外业可同时进行控制测量和碎步点同测,在一个测站上把需要做的外业工作做完,可以不需要先控制后碎步分开观测,以减少重复性劳动。
用户提交数据文件后,在网络正常的情况下一般十几秒钟左右便可得到结果。系统经过一系列运算处理后向用户推送各种成果网页、图文结合、自动生成各项成果报告,用户只需浏览、打印或复制、下载即可。本软件具有良好的数据保密性。

本软件的一个显示特点是力争工作过程的高度自动化和智能化。
本软件适合于生产、科研与教学使用。
(1)用户只需把观测数据文件整理好,争取一次提交成功。
(2)用户只要掌握对每一个未知点的平面独立观测条件不少于2个即可。这可称为基本观测条件。但,整个控制网要有一定数量的多余观测条件才能达到平差的目的。例如,一个未知点的交会至少要有一个多余观测条件。多余观测条件的多少要根据控制网的精度要求、技术文件要求、实际用途、重要程度等因素适量确定。
(3)操作步骤: 设置 → 选项 →提交数据文件 → 浏览成果(各种成果项参见主要页面介绍和平差例子录像)。
对于四等以下的平差项目,大多数使用缺省设置就可以了,这时只需要提交数据文件即可得到所有成果。
(4)错误检查方面。虽然本软件能够自动检查出大量错误并反馈给用户修改数据文件,但用户应该主动检查并消灭数据文件中的所有错误,力争一次提交成功。把本软件的自动检查作为最后的补充检查,以帮助用户发现比较隐蔽的错误之用。
除“用户需要做的工作”之外都是用户不需要关心的工作。如,用户不需要关心坐标高程如何计算、三角形及点、边和角的编号、顺序、相互关系与数量等、导线点的连接方向和顺序、何种网型以及网的复杂程度等等。本软件的后台机器人功能(人工智能)将会自动完成上述这些工作,但不限于这些工作,这里不一一列举。总之,对于控制网中的复杂逻辑,由本软件负责处理。
我们仍在不断努力,让用户的工作越来越少、负担越来越轻。给用户创造一种轻松快捷的工作环境。
本软件可广泛应用于规划、勘察、工程设计与施工阶段的测量定点、平差计算、变形监测等。也可以应用于其它重要领域。能够对遥远的目标进行定位(遥远是指用望远设备观察到的最远目标)。本软件系统存在潜在应用。如果用全站仪配合GPS工作将会使得本软件系统发挥更大、更重要的作用。
本软件尤其可以对不可到达、或难以到达、或达到代价过高过大的目标进行观测以获取精确的坐标和高程。并且更适合于采用其它设备进行定点、建网困难较大、经费消耗太高的项目。更重要的是本软件系统实现了工作过程的高度自动化和智能化,以大幅度减少人力资源投入、大幅度减轻工作人员的劳动强度。
对于一个具体的大中型工程项目,若利用本软件系统对工作方案布置设计得当,可以大大减少测量专业人员的投入人数,并实现高速、高效完成规划勘察、设计和长期施工观测方面的有关生产任务。
利用本软件能够解决用传统方法难以解决的问题。例如,对存在巨大障碍甚至通视障碍(如大型河流相隔、崇山峻岭阻挡等)的目标以最少的代价进行精确的观测定位。
本软件系统并不局限于上述应用。
本软件适合现有的观测方案和未来的观测方案。
现有的控制网观测方案包括目前已有的各种交会、各类导线网、测角网、测边网、边角网、各类控制网及典型图形等以及概述中所提到的各种方案。未来的观测方案是具有一定的创造性以解决一些特殊的技术问题。这便是任意网的特征。
有些任意网,从形式看可能很复杂,但却使得工作人员的实际劳动时间缩短、劳动强度降低、生产经费降低等。
构造任意网的目的是为了工作更省时省心,并且同样满足总的精度要求和质量要求。往往构造更复杂的任意网是为了换取更容易的设计和实际工作的开展、更节省经费和总的资源消耗,其复杂的逻辑交由本软件系统去完成分析、判断和数据处理以及向用户推送成果。不论多么复杂的任意网,其观测数据文件的形式都是统一的和简洁的。关于以上这些,需要用户在实际应用中进一步了解。
因为任意网是随人的意志顺其自然而产生,不需要花费太大的精力,而只需掌握对每一个未知点的平面独立观测条件不少于2个、同时满足技术文件所规定的要求(如必要的测回数、必须观测的目标、规范规定的要求等)即可。另外,对于重要的工程部位,为了进一步提高精度和可靠性,可以在基本观测条件的基础上适当增加若干容易获取的独立观测条件。但,对于一般性的测量区域只要在基本观测条件的基础上包含有一定数量的检查条件就可以了,例如多后视支导线。
关于容易取得的观测值,例如对具有明显标志的目标进行方向观测就很容易,瞄准目标后记录读数就可以了。因此,凡是容易瞄准观测方向的目标应该尽可能的观测,因为方向观测很容易取得高质量观测值,即精确瞄准目标按下记录键。只要这些目标能起到良好的控制作用,目标自然明显都可以充分利用。但,对于取得比较困难的观测值,除非为了满足基本观测条件和技术文件要求,一般不建议多余观测。增加多余独立观测条件应本着先易后难的原则,对容易观测的目标所取得的观测值数量已经满足控制网精度及可靠性要求以后,就不再去考虑那些观测代价高的目标了。
增加独立观测条件对于提升整个网的精度是明显的,但过多的多余观测却是一种浪费。可以在控制网工作过程中多次试运行本软件,通过查看日志文件,以了解当前的工作情况、把握工作进度、避免过多的多余观测,以免造成人员和资源浪费等。
目前建立测角测距控制网以及定点的主流测量仪器是全站仪。但,本软件所指“全站仪”是这类仪器设备的统一代称。其主要包括经纬仪、测距仪、合体经纬仪测距仪、全站仪以及未来的新型测角测距仪器设备。凡是具有测角测距功能的仪器设备都适用于本软件系统,使用这些仪器设备得到的统一观测数据文件都可以提交本软件系统进行同样的处理。
