Single Sign On (Single Sign On), abbreviated as SSO, is one of the more popular solutions for business integration of enterprises. SSO is defined as the fact that in multiple applications, a user only needs to log in once to access all mutually trusted applications. However, the conventional single sign-on has the following disadvantages:
1) is not conducive to reconstruction
Because of the many systems involved, reconfiguring must be compatible with all systems, which can be time consuming
2) Unattended desktop
Since the login is only required once, all authorized application systems can access the login, which may cause some important information to be leaked.
The traditional single sign-on can not solve the problem of login among multiple systems by directly using WeChat, and the traditional field management system can not realize on-site card-punching attendance of field personnel and effectively and intuitively track the location of the project because a plurality of projects are simultaneously constructed and the mobility of the field personnel is large, so that whether the picture is shot on site or not can not be effectively judged, and closed-loop management can not be efficiently formed.
Accordingly, those skilled in the art have endeavored to develop a field management application system necessary to manage the full lifecycle of the associated work.

Detailed Description
The technical contents of the preferred embodiments of the present invention will be more clearly and easily understood by referring to the drawings attached to the specification. The present invention may be embodied in many different forms of embodiments and the scope of the invention is not limited to the embodiments set forth herein.
Example one
Fig. 1 shows a set of field management application systems required for managing the whole life cycle of related work based on gas pipeline construction, and the field management application systems comprise: the system comprises a project access layer, a management configuration layer, a data acquisition layer and a service management and control layer. The system is realized by adopting a mobile phone end application and a server end management platform application based on the WeChat enterprise number.
The field management application system is realized by adopting a user unified authorization system. Establishing a set of user management system corresponding to the enterprise micro-signal user and the enterprise user management platform to realize the association binding of the enterprise user and the micro credit user; the method has the advantages that the user of the WeChat enterprise number can log in and authenticate the basic information of the user in a single point without secondary login; the automatic authorization of the WeChat enterprise number user on the server management platform is realized.
At present, a user unified authorization system manages identity information and corresponding relations among application identities of different application systems such as a company pmis project management system, an enterprise micro signal, an oa management system and the like, so that identities of the same user in all the application systems are consistent, and an application program does not need to care about an identity authentication process.
The data acquisition layer of the field management application system adopts a mobile terminal multi-place check-in assessment system. Due to the particularity of gas pipeline construction, project managers need to manage a plurality of construction sites at the same time, work fluidity and change are strong, and attendance of such site personnel management cannot be checked through common modes such as punching cards by a unit attendance machine. The automatic checking and comparing function of the relation among the corresponding items of the check-in time, the check-in place and the check-in is established, and the validity of the check-in and attendance information is ensured. Different from the traditional mobile terminal attendance, the attendance checking method is characterized in that one project manager needs to manage a plurality of construction sites simultaneously for the attendance checking of the project construction sites, and the attendance checking of a plurality of places is realized.
The field management application system has a project billboard function. And displaying the tracking item condition in a map mode. The map, the project, the geographical position, the project site navigation and the latest condition of the project are provided for checking, and the project can be checked on site conveniently.
The field management application system adopts a project circle management mode. The idea of field project management is that the progress of each project can be known and mastered at the first time, and the field situation can be communicated and fed back in real time when a problem exists. In order to achieve the point, the project is subjected to bold innovation on the aspects of management concept and user experience. A management mode similar to a WeChat friend circle is introduced, meanwhile, a personalized management means is added on the basis, and breakthrough attempts are made on timeliness and interactivity of field management. In timeliness, after the collected data is submitted by field collection personnel, the system can automatically synchronize related information to a project circle, and issue project element information, collected person information and collected photo information in a mode similar to that of a WeChat friend circle; in the interactive aspect, the branch management auditors can directly audit the release content through the pc management terminal or the project circle, if any, the two parties can communicate with each other through a reply mode to the condition of a certain collected photo or the whole condition, the problem can be solved in a closed loop mode, and meanwhile, a tracing log of the problem is formed.
Example two
Fig. 2 is a schematic structural diagram of a user unified authorization system.
Structurally, the user unified authorization system consists of three parts, namely a unified identity authentication management module, a unified identity authentication server and an identity information storage server.
The unified identity authentication management module consists of a management tool and a management service, and realizes user group management and user management; the management tool realizes interface operation and submits the operation data to the management server, and the management server modifies the content in the storage server.
The uniform identity authentication server provides uniform Webservice authentication service for the application program. The authentication token of the user is returned to the application program after the authentication is passed.
EXAMPLE III
And the data acquisition layer of the field management application system adopts dynamic digital watermarking. The collection of the on-site photos requires examination of each collected photo for each key point due to the requirements for the construction site management, so as to ensure the faithful feedback of the on-site conditions and the problem discovery. The workload for the examiners is very large, and how to assist the examiners in intelligently screening the photos through an information technology means for the authenticity and the effectiveness of the collected photos is also a technical highlight of the project. By investigation and on-site typesetting, the auxiliary technology for photo collection adopts the dynamic watermarking technology of photos. The system automatically identifies the relevant information of the project through intelligently analyzing the collected photos according to the information of the collection time, the collection place and the like, and simultaneously adds the watermark information relevant to the project on the photos, thereby ensuring the real effectiveness of the collected photos (intelligently eliminating invalid photos uploaded in real time on site) and facilitating the subsequent browsing and inspection of the sampled photos.
The digital watermarking technology is a computer information hiding technology based on a content and non-password mechanism. It is to embed some identification information (i.e. digital watermark) directly into the digital carrier (including multimedia, document, software, etc.) or indirectly (modifying the structure of a specific area), and it does not affect the use value of the original carrier, and is not easy to be ascertained and modified again. But can be identified and recognized by the producer. The information hidden in the carrier can achieve the purposes of confirming content creators and purchasers, transmitting secret information, judging whether the carrier is tampered or not and the like. Digital watermarking is an effective method for protecting information safety, realizing anti-counterfeiting tracing and copyright protection, and is an important branch and research direction in the field of information hiding technology research.
1) Safety: the information of the digital watermark should be safe and difficult to be falsified or forged, and meanwhile, the false detection rate should be low, and when the original content changes, the digital watermark should change, so that the change of the original data can be detected; of course, the digital watermark also has strong resistance to repeated addition;
2) concealment: digital watermarks should be imperceptible and should not affect the normal use of the protected data; the quality is not degraded;
3) robustness: this property is suitable for robust watermarking. That is, the digital watermark remains partially intact and can be accurately authenticated after undergoing various unintentional or intentional signal processing procedures. Possible signal processing procedures include channel noise, filtering, digital/analog and analog/digital conversion, resampling, shearing, displacement, scale change, lossy compression coding and the like;
4) sensitivity: this property applies to fragile watermarks. After the distribution, transmission and use processes, the digital watermark can accurately judge whether the data is falsified. Furthermore, the position and the degree of data tampering can be judged, and even the original information can be restored.
In the digital watermarking technology, a digital watermarking algorithm based on discrete wavelet transform is adopted, compared with the traditional DCT transform, the wavelet transform is variable in resolution, an analysis method combining a time domain and a frequency domain is adopted, the size of a time window is automatically adjusted along with the frequency, and the human visual characteristics are better met. The wavelet analysis has good locality in time and frequency domains, and provides good combination for traditional time domain analysis and frequency domain analysis.
(1) For discrete wavelet transform we define some signals and filters that need to be used, as shown in fig. 3.
x [ n ]: discrete input signal of length N.
g [ n ]: the low pass filter can filter the high frequency part of the input signal and output the low frequency part.
h [ n ]: the high pass filter filters out the low frequency portion and outputs the high frequency portion, as opposed to the low pass filter.
↓andQ: the downsampling filter outputs y [ n ] ═ x [ Qn ] if x [ n ] is used as input. Here, Q is 2.
After the above symbols are clearly defined, the hierarchical structure can be used to describe how to perform discrete wavelet transform on a discrete signal, as shown in fig. 4.
α th layer of the architecture (α th stage)
(2) In wavelet analysis, it is often used to approximate details, which represent the high-scale, i.e., low-frequency, information of a signal; the details represent the high scale, i.e. high frequency information, of the signal. As shown in fig. 5, for a noisy signal, the main energy of the noise component is concentrated in the detail component of the wavelet solution.
In digital image processing, continuous wavelets and their wavelet transforms need to be discretized. In general, a binary discrete process is used in computer implementation, and the wavelet subjected to the discretization and the corresponding wavelet transform are converted into discrete wavelet transform (DWT for short). In practice, the discrete wavelet transform is obtained by discretizing the scale and displacement of the continuous wavelet transform by a power of 2, and is also called binary wavelet transform.
Although the classical fourier transform may reflect the overall connotation of the signal, the representation is often not intuitive and noise can complicate the signal spectrum. In the field of signal processing, a family of bandpass filters has been used to decompose a signal into different frequency components, i.e., signal f (x) is fed to a family of bandpass filters hi (x).
The significance of wavelet decomposition is that the signal can be decomposed on different scales, and the selection of different scales can be determined according to different targets.
For many signals, the low frequency component is important, often implying a characteristic of the signal, while the high frequency component gives details or differences in the signal. Human voice, if the high frequency components are removed, sounds different from before, but still knows what is being said; if enough low frequency components are removed, some meaningless sound is heard. Approximation and detail are commonly used in wavelet analysis. Approximately represents the high-scale, i.e., low-frequency, information of the signal; the details represent the high scale, i.e. high frequency information, of the signal. Thus, the original signal passes through two mutual filters to produce two signals.
By continuously decomposing the approximate signal through a continuous decomposition process, the signal can be decomposed into a plurality of low-resolution components. In theory the decomposition can proceed without restriction, but in fact the decomposition can proceed until the detail (high frequency) contains only a single sample. Therefore, in practical applications, the appropriate number of decomposition layers is generally selected according to the characteristics of the signal or an appropriate standard.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
