Computer/upper computer show various signal intensities (hydraulic pressure, water level, temperature etc.) on screen.Slave computer is direct
Control device obtains the computer of status of equipment, usually PLC/ microcontrollers single chip microcomputer/slave
Computer/lower computer's etc.The order that host computer is sent out gives slave computer, slave computer to be ordered further according to this first
It is construed to corresponding time sequence signal and directly controls relevant device.Slave computer reads device status data (generally analog quantity) frequently,
It is converted into digital signal and feeds back to host computer.Conceptually, controller and service provider are host computer, controlled person and bedding and clothing
Business person is slave computer, it is understood that is the relationship of host and slave, but host computer and slave computer can be converted.
Further, above-mentioned multi-protocol gateway equipment can integrate ICP/IP protocol, CAN protocol (Controller Area

And ethernet device) and a variety of different communication protocols such as Bacnet agreements, and can realize the conversion between above-mentioned various protocols.
I.e. the multi-protocol gateway equipment can receive the data of above-mentioned a variety of different self-defined Transmission Control Protocol transmission, the acquiescence of source device
Data frame can be TCP/IP data frames or various customized Transmission Control Protocol data frames.
The source signal of acquisition is parsed, the data segment to parse the communication protocol data frame that source signal includes is believed
Breath, data segment information includes source address, valid data section and destination address.
Specifically, so-called data frame (Data frame), is exactly the protocol Data Unit of data link layer, it includes three
Point：Frame head, data portion, postamble.Wherein, frame head and postamble include some necessary control information, such as synchronizing information, address
Information, error control information etc.；Data portion includes then the data, such as IP data packets etc. that network layer hands down.In general, sending out
Sending end, data link layer network layer hand down data are packaged into frame, be subsequently sent to link up；In receiving terminal, data
Link layer takes out the data in the frame received and gives network layer.Different data link layer protocols corresponds to different frames,
So there are many frames, for example PPP frames, mac frame etc., specific format are also not quite similar.
In the present embodiment, wherein source address, valid data section, destination address are in data portion, specifically, source
Location indicates the address for being originally sent equipment of source signal, such as the address of client；Destination address indicates what source signal eventually arrived at
The address of target device, such as can be the address of insurance service equipment.Further, source address and destination address can be adopted
It is identified with (such as 7) byte mode of preset quantity.If in the data segment information parsed not including source address or mesh
Address, then each byte of its source address or destination address is disposed as 0.
Valid data section refers to be converted to the data segment of Json data frame formats in data segment information.
Further, in some other embodiment, the source signal of acquisition is parsed, to parse source signal packet
The step of data segment information of the communication protocol data frame contained further includes following steps：
Calculate the character information length of the valid data section parsed；
Character information length is analyzed according to the calculation of cyclic redundancy, obtains check code；
According to the check code of acquisition, determine source signal whether reliability.
In general, the valid data section and data length that will be obtained from source signal, according to the calculation of cyclic redundancy
The legitimacy for calculating and obtaining check code, and accessed according to the verification code check source device obtained is calculated.Specifically, cyclic redundancy
It is most common a kind of error check code in data communication field that calculation, which calculates and obtains check code, it is characterized in that information field
Length with check field can be arbitrarily selected.It generates the basic principle of check code：Any one is by bit string group
At code can be only with a coefficient 0 and 1 value multinomial correspond.Such as code 1010111 is corresponding more
Xiang Shiwei x6+x4+x2+x+1, and it is 101111 etc. that multinomial, which is the corresponding codes of x5+x3+x2+x+1,.And verify code collection selection
Principle be：If setting the code word size of check code as N, information field is K, and check field is R (N=K+R), then for inspection
Any code word in code collection is tested, exists and there is only a R order polynomial g (x) so that V (x)=A (x) g (x)=xRm (x)+r
(x)；Wherein, m (x) is K-1 message polynomial, and r (x) is r-1 check polynomial, and g (x) is known as generator polynomial, specifically

For the predefined byte for identifying the data frame type of target device support, generally a byte.The work(of target device
Energy code is the byte of the data frame type for identifying target device support.
The valid data section obtained to parsing parses, and obtains the access parameter of target device, and according to target device
Function code convert obtained the accesss parameter of parsing to the data frame format that target device is supported, be sent to target device.
Specifically, the valid data section that parsing obtains is converted into Json data frames first；Generally, due to valid data section
It can be formed by specific Json frame formats data conversion, therefore, by source signal resolving, acquisition can be converted into
For the data segment of Json data frame formats as valid data section, the frame type of the valid data section is the frame class of Json data frames
Type.And it further parses the valid data section and obtains Json data frames.Since usually used Ethernet or WIFI modes are made
For bottom transmission medium, can all be related to ICP/IP protocol, application layer usually using HTTP mode, so selection uses Json
The transmission frame as valid data section of data frame can easily parse the access parameter of target device.
Specifically, Json data frames are parsed, obtains the access parameter of target device, and according to the work(of target device
Energy code converts the access parameter that parsing obtains to the data frame format of target device support, is sent to target device.
Specifically, interface function corresponding with Json data frames can be called, and is obtained according to the interface function of calling
The Json attributes and preset Json fields are accessed table progress by the Json attributes of the corresponding character string forms of Json data frames
Match, can know the access parameter of target device.Further, the access parameter of the target device of acquisition is converted to 16 systems
Data, and the data of 16 systems are further converted to the data frame format of target device support, in order to by target device
Access parameter be sent to target device.
By above-described embodiment it is found that gateway device proposed by the present invention, the source signal sent by obtaining source device, and it is right
The source signal of acquisition is parsed, and to parse the data segment information of source signal, the data segment information includes source address, effectively
Data segment and destination address；Then according to the mapping relations between pre-stored function code and destination address, purpose is determined
The function code of the corresponding target device in address, the function code is the byte of preset kind length, for identifying target device branch
The data frame type held；Finally the valid data section is parsed, the corresponding access parameter of target device is obtained, according to mesh
The access parameter that the function code of marking device obtains parsing, is converted into the data frame format of target device support, and is sent to mesh
Marking device, the valid data section include the access parameter of target device.Improve the versatility of gateway device.
