The present invention is based on power grid OMS system in the case where not accessing external network, realizes the accurate transmitting-receiving of dispatching of power netwoks instruction,
Specific implementation process is as follows：
When sending instruction, instruction input terminal computer (i.e. power grid control terminal) will be implemented by artificial mode,
CRC data packet is generated by des encryption by computer, digital and analogue signals are converted to by language by RS232 serial ports or RJ-11 interface
Sound signal.
In dispatch command encryption, in the way of DES symmetric cryptography, the characteristics of cipher mode is that enciphering rate is fast,
The composition of password adds sending time minute to form by receiving device sequence number, generates CRC (cyclic redundancy check) check code, with
Guarantee the integrality of transmitted data packet, to determine that data will not lose, then passes through RS232 serial ports or RJ-11 interface
Digital and analogue signals are converted into voice signal, then carry out the transmission process of voice signal.
It instructs in transmission process, the transmitting voice signal that dispatching of power netwoks terminal issues to cable modem or voice
Dispatching desk is sent to communication base station by cable run mode, and is sent in handheld device by exclusive number.Operator
Hand-held intelligent terminal can be mobile phone or tablet computer.
Instruction with transmitting voice signal during transmitting voice signal to cable modem or voice scheduling platform
In, pulse signal is converted to digital signal, is transferred in communication base station by communication cable, communication base station and staff's hand
In handheld device contacted using exclusive number, pass through the special biography between communication cable and communication base station and handheld device
Mode is passed, the requirement of outer net cannot be connected by meeting dispatching of power netwoks, meet the safety of instruction transmitting.
The reception of instruction is that uniquely corresponding communicating number carries out transmission reception with hand-held intelligent terminal by communication base station,
The object for guaranteeing information transmission is not in mistake.
Conversion display can be decrypted in instruction decryption acquisition process by the decryption system built in hand-held intelligent terminal.
Further, it is also possible to install a corresponding software, the instruction for will receive in hand-held intelligent terminal
Decryption conversion, the hand-held intelligent terminal machine code that each operator uses be it is unique, when hand-held intelligent terminal receive from
After the instruction of base station transmission, software obtains the voice signal of encryption automatically, and opposite with encryption to speech signal progress is decrypted
Journey, the instruction text after decryption show operator in a manner of short message, and operator requires implementation according to instruction.
In entirely instruction transmission process, text instruction, by pulse encrypted transmission, is met by being converted to phonetic order
The security requirements of power grid built-in command transmission meet the requirement of power grid instruction transmission intermediate equipment and medium, in transmission process
In, the danger lost and stolen by people will not can occur as File Transfer for instruction, and simple File Transfer is in transmission speed
It is had certain disadvantages in encryption, is not suitable for the efficient of electrical grid transmission requirement, safety.
The present invention is transmitted by way of turning voice signal to dispatching of power netwoks instruction text, and at operator also
Originally it was the mode of text instruction, and avoided the risk that power grid tradition causes information to misinformate by voice delivery instruction, avoid accident
Generation, meanwhile, in the transmittance process of text instruction, text is encrypted, digital-to-analogue conversion is transmitted by cable, base station
With the exclusive contact method of handheld device, hand-held intelligent terminal ciphertext data, and scheduling controlling is referred in a manner of text information
Order is presented to staff, both meets the characteristics of dispatching of power netwoks cannot rely on outer net, in turn ensures dispatching of power netwoks instruction transmission
Safety prevents Transmission system from being attacked and being caused the generation for the problems such as instructing error of transmission by external network, can be in various needs
