Description

Method for establishing engineering information capable of realizing high accuracy

Technical Field

The invention relates to a method for automatically building engineering, in particular to a method for building engineering information with high accuracy.

Background

The existing commercial air conditioner data service cloud platform can remotely collect and analyze the operation data of the commercial air conditioner unit, timely provides daily maintenance information of the unit for users, and can timely give an alarm when the unit breaks down.

Usually there are the mainboard of a plurality of DTU modules and a plurality of tape unit bar codes under a commercial air conditioning engineering, when the engineering was debugged, moreover, the debugging personnel need often switch the debugging with the DTU module between different engineering, led to the identity sign of engineering often to change to cause the inaccuracy that engineering information established.

For example: as shown in fig. 1, a DTU module a + motherboard unit bar code a is provided under an engineering a, a DTU module B + motherboard unit bar code B is provided under an engineering B, and when the data received by the automatic engineering server from a certain DTU module is the DTU module a + motherboard unit bar code B, the situation may be two cases, the first case is that in the engineering a site, a motherboard is taken from the engineering B and the motherboard of the engineering a is replaced; the second case is that at the project B site, we have taken the DTU module from project a and replaced the DTU module of project B. The data received by the server is the DTU module A + the main board unit bar code B under the two conditions, and the two conditions are possible to occur and only have different occurrence probabilities. When the program is used for judging, only the second case with high probability is selected to improve the accuracy of the engineering, and the first case with low probability is ignored, but the first case with low probability is also possible, so that the inaccuracy of the engineering information establishment is generated. In actual engineering, one project can be composed of 16 DTU modules and 16 main boards at most, and each DTU module or main board can be replaced by a DTU module or main board in other projects, so that judgment is carried out by purely building a project server program, only a large probability event can be selected, and the accuracy cannot reach 100%.

Disclosure of Invention

In order to solve the technical problem that the construction accuracy of the engineering information cannot reach 100% in the prior art, the invention provides a construction method of the engineering information, which can realize high accuracy.

The invention relates to a method for establishing engineering information, which comprises the following steps: when a new project or a communication component of the project is changed, acquiring unique identification numbers of all communication components under the project; sending the unique identification numbers of all the communication components and the labeling information of the project to a remote server for storage; receiving engineering information sent by any one communication component and an identification number associated with the communication component; and finding the stored identity identification and the corresponding marking information of the corresponding project according to the identification number, newly building or finding the project, and updating the project information into the project.

Specifically, the project is newly built or found through the project building server, and the project information is updated to the project. The remote server is a storage server. The labeling information comprises an engineering name.

In an application embodiment, the project is a project corresponding to a commercial air conditioner. The communication component is a DTU module. The unique identification number of the DTU module is an IMEI number. The identification number associated with the DTU module includes its own unique identification number.

Preferably, the identification number further includes unique identification numbers of all the unit main boards. The unique identification number of the unit mainboard is a unit bar code.

The invention scans the two-dimensional codes on all DTU modules under the project by debugging personnel, binds the unique identification number information of all DTU modules of the project together, uploads the unique identification number information to the storage server, and then cooperates with the automatic construction server to automatically construct the project logic to establish the project, thereby solving the problem of wrong project identification caused by the switching of the DTU modules between different projects, ensuring that the accuracy of newly constructed projects can reach 100 percent accuracy, and providing a powerful guarantee for the accurate big data analysis of engineering units.

The invention is described in detail below with reference to examples and figures, in which:

fig. 1 is a schematic structural view of the problems of the prior art of the present invention.

FIG. 2 is an engineering building block diagram of the present invention.

FIG. 3 is a flow chart of the engineering setup of the present invention.

Detailed Description

The principles and embodiments of the present invention are described in detail below with reference to the accompanying drawings.

The invention explains the construction information establishing method of the invention by the relatively complicated situation of a commercial air conditioner. Because usually there are a plurality of DTU modules and a plurality of mainboard of taking the unit bar code under the engineering that a commercial air conditioner corresponds, every DTU module has a unique IMEI number of the whole world as unique identification number, every mainboard with bar code also has a unique unit bar code of the whole world as unique identification number. All IMEI numbers + unit barcodes under the project are combined to form the identity of the project. However, during engineering debugging, a debugging person needs to frequently switch and debug the DTU modules of different projects, which causes the identity of the project to be frequently changed, and although the accuracy of the project information after the DTU is switched is improved by a certain project building logic algorithm in the early stage, the accuracy still cannot reach 100% accuracy.

As shown in fig. 2 and fig. 3, when a new project or a communication component of a project is changed, since a debugging worker debugs the project on a project site, the debugging worker can sequentially scan two-dimensional codes on chip backs of all DTU modules under the project by using an App to obtain IMEI numbers of all DTU modules under the project, and then the debugging worker manually inputs labeling information of the project, such as a project name, and sends the IMEI numbers of all DTU modules and the labeling information of the project to a remote server for storage.

Although a project contains a plurality of DTU modules, in order to avoid repeated transmission, the project information (such as data on a bus) can be transmitted to a server only by one DTU module at the same time. Specifically, data is uploaded by which DTU module, election needs to be performed between DTU modules, and after certain election logic between DTU modules is judged, one DTU module is elected to upload engineering information. For example, a DTU module with the lowest current load and the best transmission speed may be selected to transmit the engineering information. Meanwhile, the DTU module can also transmit the IMEI number of the DTU module and the unit bar codes of all the mainboards back to the automatic construction engineering server, and can also only transmit the IMEI number.

The automatic engineering construction server inquires the IMEI number from the storage server, thereby determining the identity and the corresponding marking information of the engineering corresponding to the IMEI number, newly building or finding the corresponding engineering, and updating the engineering information into the engineering. Specifically, the automatic engineering building server increases, decreases or updates the existing engineering information in the system according to the identity of the engineering, and completes the engineering building step.

The engineering information established by the method can achieve 100% accuracy no matter how the DTU module in the engineering is added or deleted or replaced by the DTU modules of other multiple engineering, and the condition of wrong establishment of the engineering information is avoided.

Two cases in fig. 1 are taken as examples.

When the automatic engineering construction server receives data sent by the DTU module, namely the DTU module A + the main board unit bar code B, a debugging person knows which condition is actually the situation because the debugging person is on the spot, if the situation is on the project A spot, the debugging person scans the IMEI number of the DTU module A through the App, binds the identification information of the project A and sends the identification information back to the storage server, then the automatic engineering construction server finds the information of the project A on the storage server through the IMEI number of the DTU module A, the automatic engineering construction server can determine that the main board of the project A is replaced by the project B, and then corresponding subsequent engineering construction processing is carried out.

If the situation is that the situation is on the site of the project B, debugging personnel scan the IMEI number of the DTU module A through the App, and then bind the identification information of the project B and transmit the identification information back to the storage server, then the automatic project building server finds the information of the project B on the storage server through the IMEI number of the DTU module A, and can determine that the DTU module of the project B is replaced by the project A, and then corresponding subsequent project building processing is carried out.

The noun explains:

a DTU module: and the Data Transfer Unit Data transmission Unit is connected to the air conditioning Unit bus, monitors bus Data, packs all Data on the bus and sends the Data to the cloud platform server. And a sim card of a mobile operator is inserted into the DTU module, and data is transmitted through the sim card and the mobile operator network.

Machine set bar code: each air conditioning unit mainboard can burn a specific bar code when leaving the factory, and the bar code has global uniqueness.

Engineering identity marking: a plurality of DTU modules and a plurality of mainboards with unit bar codes are arranged under a commercial air conditioning project, each DTU module has a globally unique IMEI number, and each mainboard with the bar codes also has a globally unique unit bar code. And combining all IMEI numbers and the unit bar codes under the project to form the identity of the project.

DTU election: a project comprises a plurality of DTU modules, but only one DTU module can transmit the data of the project to the server at the same time. Specifically, data is uploaded by which DTU module, election needs to be performed between DTU modules, and after certain election logic between DTU modules is judged, one DTU module is elected to upload data.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
