At present, each link of coking coal sampling has an artificial interference mode, so that the influence factors are more, the coal information is artificially interfered in the middle, and the actual situation of the coal cannot be truly reflected.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the factors of coal information leakage and artificial interference are avoided, and the requirement of actual production is fundamentally met.
The technical scheme adopted by the invention is as follows: a method for intelligently coding and transmitting coal information of a coking coal sampling control system comprises the following steps
Step one, distributing a characteristic code for each coal of all the used coking coals to form a coal type information characteristic code table;
step two, the sender acquires (manually and directly acquires) the coal information comprising the characteristic codes, formulates an encryption algorithm, encrypts the characteristic codes of the coal information to form transmission data, and sends the transmission data to the receiver through a digital output module of the sending logic controller;
and step three, the receiver receives the transmission information through a digital receiving module of the receiving logic controller, decodes the transmission information according to a decryption method provided by the sender to obtain the coal type information comprising the feature codes of the coal type information, and then obtains the coal type information through a coal type information feature code table.
The feature code is a number corresponding to the coal type one by one.
And in the encryption process in the second step, computer binary coding is carried out on each feature code to form a digital information signal code of the coal feature code, and the digital information signal code is subjected to mask encryption by using a specified mask.
The receiving party and the transmitting party are connected through a signal communication cable with a shield.
The program side of the encryption and decryption methods is located elsewhere in a u-disc, the program u-disc with the encryption method being held by the sender and the program u-disc with the decryption method being held by the recipient.
The invention has the beneficial effects that: the system is used for the coal preparation sampling control system of the Tai-Gai coking plant, has good effect, can accurately and safely transmit the coal information between the central control and the laboratory after the system is put into use, avoids the factors of coal information leakage and artificial interference, fundamentally meets the requirement of actual production, and indirectly creates economic benefit.
Detailed Description
In terms of hardware: a set of independent control station (a sender computer) is configured at a sender, a receiver computer is a central control and sampling machine, and the sender computer and the receiver computer are directly connected through a multi-core shielded cable.
Software aspects
Sending hair
(A) Sending and acquiring coal type information (the Tai Steel needs to transmit and use 32 coal type information);
(B) the sender and the receiver negotiate, and a coal type information characteristic code table is formed in a manual coding mode (Tai Steel adopts 1-32 Arabic numbers to correspond to 32 types of coal to form the coal type characteristic code table, and the sender and the receiver can negotiate and adjust which code corresponds to which type of coal information at any time to ensure the confidentiality of coal type information transmission);
(C) the coal characteristic code table is subjected to computer binary coding to form a digital information signal code of the coal characteristic code (32 coal characteristic codes in the Tai-Gai-Steel can be represented by 5-bit computer binary digits (2)5=32））;
(D) The digital information signal code of the coded coal characteristic code is subjected to mask encryption by using a specified mask (any value from 0 to 255 can be used), the digital information signal code of the coded coal characteristic code is encrypted by using 224 specified mask in the Taigang, and the digital information signal code is packed into a transmission byte, because one byte is 8 bits, the lower 5 bits of the byte are used, and the rest is spare;
the digital information signal sending packet of the coal type feature code is formed by carrying out software programming on the information through a sending logic controller (most logic controllers on the market can be realized), the sending packet is sent out through a digital output module (DO module for short) of the sending logic controller (Siemens uses Siemens WINCC man-machine interaction software as an upper computer, appointed coal type information feature codes of the secondary sampling are sent to a Siemens PLC400 system of a lower computer according to a coal type information feature code table formed in the steps (A) and (B), the PLC400 system of the lower computer adopts step7 software to complete the steps (C) and (D), namely, the received appointed coal type information feature codes are subjected to coding mask of computer binary information and packaged to form a sending packet to be transmitted, and the completion process of the four steps (A), B, C and (D) forms a complete privatization communication protocol, the protocol is completely independent of common protocols widely used in the market (such as PROFIBUS-dp, Ethernet and the like), and the safety of information transmission is ensured;
transmission process
Laying 12-core signal communication cables with shields, connecting one end of each signal cable to a digital output module DO appointed by a sending end, connecting the other end of each signal cable to a digital input module DI appointed by a receiving end, and then transmitting digital information signals of the coal type feature codes packaged by the logic controller to the receiving end (the Tai steel uses the shielded control cable with the specification of KVVP7 x 1.0 for 200 meters, only uses 5 cores, and the rest is reserved);
receiving party
The receiving end receives signals through a digital input DI module (Siemens S7200smart system integrated digital input module DI adopted by the receiving end Tai Steel carries out signal receiving and acquisition);
the received digital information signal of the specified coal type feature code is subjected to reduction decryption of computer binary information through a receiving logic controller (most logic controllers on the market can be realized), the specified coal type information feature code is finally reduced by adopting reverse mask code and decoding processing and is output to a display touch screen (the receiving logic controller adopted by the receiving end Tai Steel is a Siemens S7200smart system integrated digital input module DI, and the output display adopts a matched Siemens HMI700ie to touch a display panel), and the decryption is a process of unpacking the privatized communication protocol;
the characteristic code of the specified coal information acquired from the display touch screen is restored into the real coal information transmitted by the transmitting terminal according to the coal information characteristic code table so as to be used in the next procedure, and thus, the whole process of coal information coding transmission is completed.
The program side of the encryption and decryption methods is located elsewhere in a u-disc, the program u-disc with the encryption method being held by the sender and the program u-disc with the decryption method being held by the recipient.
