The data confirmation module is operated on the wireless communication module and is used for continuously judging whether the temperature data and the humidity data which are guided in a dialog box on the touch screen by a user and are transmitted to the main controller are error-free temperature data and humidity data transmitted to the main controller or data which require the confirmation of the user and require the coding after receiving the command of requiring the coding, wherein the alias and the identification code are also added in the error-free temperature data and humidity data transmitted to the main controller.
In detail, after receiving the command requesting data encoding, the data confirmation module performs confirmation in the following states:
the first state: confirming non-empty and uninterrupted strings which are higher than 32bits and have 'alias', 'identification code' or pause numbers in the imported temperature data and humidity data transmitted to the main controller, and coding the temperature data and the humidity data transmitted to the main controller without errors as the temperature data and the humidity data transmitted to the main controller without errors when the strings are not higher than 32 bits; when the character string exceeds 32bits, prompting the user to check whether the imported temperature data and humidity data transmitted to the main controller are correct, if the data are continuously imported, abandoning confirmation, and taking the character string as the data which is identified by the user to be coded until the first character code is imported;
and a second state: if the data such as the alias and the identification code are directly imported, the data are confirmed to be invalid data, and a prompt message can be returned to the main controller and displayed on the touch screen to prompt a user to check the data form or prompt the user to be imported again after being converted into a complete code;
and a third state: after the guided temperature data and humidity data transmitted to the main controller are higher than the upper limit values of the capacities of the set temperature data and humidity data, all subsequently guided data are used as invalid temperature data and humidity data transmitted to the main controller, a prompt message can be returned to the main controller and displayed on a touch screen to prompt a user that too much invalid alias data are guided in, and the user can guide in the data meeting the standard again or prompt the user to convert the data into complete codes and guide in the data again;
and a fourth state: the method belongs to a state of executing complete coding on the imported data, which is to execute complete coding on the temperature data and the humidity data which are imported in a dialog box on a touch screen and transmitted to a main controller after receiving an instruction for requesting coding, namely the data confirmation module determines that any imported data is error-free, and is suitable for a request that a user requests that the data except alias data also execute coding. When the wireless communication module transmits an instruction requiring complete coding, the coding is carried out on the data transmitted subsequently until the coding is cancelled.
The wireless communication module is further configured to determine whether the processing platform is a usable processing platform, and if so, to transmit the encoded presentation data to the processing platform, and if not, to stop transmitting the encoded presentation data to the processing platform.
Here, before the wireless communication module transmits the encoded exhibition data to the processing platform to execute decoding, it is also able to re-confirm whether the processing platform is an available data receiver or not suitable for receiving the data in a wireless network display state by retrieving the current data transmission performance of the previous transmission target and the wireless network of the wireless communication module, so as to prevent the defect that the temperature data and humidity data transmitted to the main controller are intercepted, when the processing platform is determined to be unavailable, or when the processing platform is determined to be in a wireless network state with poor performance, even if the main controller is bound by malicious software or the data is intercepted by the malicious software, the malicious software cannot take the data to the processing platform of a thief under the condition that the main controller and the processing platform have a link, and under the condition that the data processing platform is successfully logged in by another name of the thief, the encoded data originating from the host controller is also unavailable.
The processing platform is used for receiving the coded display data and decoding the coded display data to obtain the temperature data and the humidity data transmitted to the main controller.
Here, the processing platform specifically includes a data receiving module, a delivery module that requires decoding, and a decoding module, where:
the data receiving module is used for receiving the coding display data;
the decoding-requiring transfer module is used for transferring an instruction for requiring data decoding to the wireless communication module;
the decoding module is used for decoding the coded display data by means of a decoding method returned by the wireless communication module, or decoding the coded display data by means of a decoding method contained in the received coded display data, so as to obtain the temperature data and the humidity data transmitted to the main controller.
Here, after the wireless communication module determines that the processing platform is available, the processing platform transmits corresponding encoded exhibition data to the processing platform, the processing platform decodes the encoded exhibition data directly by means of a decoding method included in the received encoded exhibition data to obtain the temperature data and the humidity data transmitted to the main controller, and if the encoded exhibition data does not include a decoding method, the processing platform transmits an instruction for requesting data decoding to the wireless communication module, so that the encoded exhibition data is decoded by means of the decoding method returned by the wireless communication module, specifically, the decoding method is not transmitted to the processing platform at the same time when the encoded exhibition data is transmitted, and the processing platform can be determined by means of specific conditions.
As long as the alias identification code is added to the temperature data and the humidity data in the main controller, the data with the alias and the identification code can be converted into a coded display mode by using the wireless communication module to perform timely coded display or delay within 6s on the temperature data and the humidity data transmitted to the main controller through the high-speed rail power supply data transmission system under the Internet of things, so that the effect of reliably protecting the temperature data and the humidity data transmitted to the main controller between different platforms is achieved through the high-speed rail power supply data transmission system under the Internet of things.
While the present invention has been described above in terms of procedures illustrated in embodiments, it will be understood by those skilled in the art that the present disclosure is not limited to the embodiments described above, and that various changes, alterations, and substitutions can be made without departing from the scope of the present invention.
