Description
Technical Field
The invention belongs to the field of high-voltage electrical equipment, relates to the transformation of the Internet of things of an electrical test instrument, and in particular relates to a virtual printer for the transformation of the Internet of things of the electrical test instrument.
Background
With the continuous expansion of the power grid scale and the rapid development of measurement technology, the test projects of electrical equipment are more and more, and a large amount of off-line test data is generated. The traditional working mode of copying test results, manually comparing test data and subjectively judging the state of equipment on site. The construction requirements of the ubiquitous power Internet of things are not met. The test data processing consumes a great deal of core labor force; misjudgment and later judgment of the health condition of equipment often lead to repeated power failure test or fault expansion of the equipment, and huge economic and social losses are caused.
At present, most of output results of electrical test instruments are output by printing test results of 'supermarket bars'. The core of the test equipment is an industrial control integrated machine, test data of the industrial control integrated machine can be printed by an embedded printer installed on an instrument besides being displayed through an LCD screen, but the printed test data is changed into paper data, the requirements of electronic storage, analysis and sharing cannot be met, and the test data is very difficult to process.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, and provides a virtual printer for the transformation of the Internet of things of an electrical test instrument, which can conveniently and wirelessly transmit test data in a virtual printing mode, so that the transformation of the Internet of things is realized under the condition that the core function and the software program of the test instrument are not changed any more.
The technical scheme adopted for solving the technical problems is as follows:
the virtual printer module comprises a data processing module, a test data receiving module, a data transmitting module and a power supply module, wherein the test data receiving module, the data transmitting module and the power supply module are respectively connected with the data processing module; the singlechip of the data processing module is internally provided with the general POS/ESC printing protocol and the information of the test instrument, and the current time information and the information of the test instrument are used as the header file of the test data to be packaged and then are sent outwards through the data sending module.
And, the data transmission module is a 4G wireless communication module.
The power supply module is a lithium battery power supply with the voltage of 4.7V and can be charged.
And the test data receiving module comprises RS232, RS485 and URAT hardware serial ports.
And the data processing module is connected with the temperature and humidity acquisition element.
The invention has the advantages and positive effects that:
the virtual printer has lower manufacturing cost and simple transformation method: only the virtual printing module is required to be additionally arranged on the original test instrument, and the original equipment body and the internal program are not required to be refitted.

Fig. 1 is a block diagram of the structure of the present invention.
Description of the embodiments
The invention will now be described in further detail by way of specific examples, which are given by way of illustration only and not by way of limitation, with reference to the accompanying drawings.
A virtual printer module for transformation of electrical test instrument internet of things includes data processing module and test data receiving module, data transmitting module, power supply module who connects respectively with it. The data processing module controls and invokes the remaining three modules.
The test data receiving module comprises a plurality of hardware serial ports such as RS232, RS485, URAT and the like, is suitable for various types of electrical test instruments, and can be connected with an output port of an original printer on the test instrument;
the data processing module takes a singlechip as a core, a POS/ESC printing protocol which is currently and internationally used is built in the singlechip, and data acquired from the data receiving module are decompiled according to the printing protocol; the data processing module is internally solidified with information of the test instrument and is simultaneously provided with a temperature and humidity acquisition element, and the current time information, the test instrument information and the environment temperature and humidity information are used as header files of test data to be packaged and then are sent outwards through the data sending module.
The data transmission module is a 4G wireless communication module, and can be used for transmitting the interpreted test data outwards by utilizing a 4G network under the control of the singlechip.
The power supply module is a lithium battery power supply with the voltage of 4.7V and can be charged by using the charging interface.
The specific application method comprises the following steps:
step one, after an embedded printer on a test instrument is taken down, selecting a virtual printer module interface according to the embedded printer interface, accessing the test instrument, and installing the virtual printer module in the test instrument.
And secondly, operating the test instrument according to the test operation procedure, normally performing a test, clicking a printing button on the test instrument after the test is completed, and transmitting test result data to the data processing module after the test result data are received by the data receiving module without printing any more.
And thirdly, the data processing module performs virtual printing decompilation on the acquired data according to a POS/ESC printing protocol, packages the test instrument information, the time information and the temperature and humidity information in the data processing module as header files of the data module, and sends the header files outwards through the 4G wireless communication module to realize the transformation of the Internet of things of the test instrument.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that it will be apparent to those skilled in the art that variations and modifications can be made without departing from the scope of the invention.
