Embodiment
The present invention proposes the communication means of a kind of host computer and MCU, comprises physical layer and data link layer, and is as shown in Figure 2, wherein:
Physical layer has defined the electric interfaces of host computer and MCU, and the physical layer between host computer and the MCU can adopt following interface standard: RS-232 interface or RS-485 interface.
The maximum transmission distance of RS-485 is 1200 meters, and the maximum transmission distance of RS-232 is 10 meters.Therefore, if when host computer and CU plate distance is far away, should preferentially adopt the RS-485 interface.
The operation of data link layer definition of data link layer is on the bidirectional information conveyance conduit that physical layer provides, the control of implementation information transmission.Data link layer converts user's request the command frame of CU plate into, is transferred to physical layer downwards; Also convert CU plate feedack into status frames and give host computer through physical layer transmission, pass to application program again, it is indifferent to physical layer and adopts which kind of these frame information of interface mode transmission.
Data link layer comprises 4 kinds of command frame and 2 kinds of status frames of returning from the CU plate of mailing to the CU plate, and every kind of command frame comprises the plurality of sub command frame again.4 kinds of command frames are respectively: the command frame of shaking hands, querying command frame, row command frame and control command frame; 2 kinds of status frames are respectively: the status frames of shaking hands and query State frame.
Facing above-mentioned each command frame and status frames down is elaborated.
One, the shake hands command frame and the status frames of shaking hands
The command frame of shaking hands is the starting point that host computer is communicated by letter with MCU, and host computer and MCU could proper communications after the success of only shaking hands.
The command frame of shaking hands is made up of frame head, postamble two parts.Specifically as shown in Figure 4.
Corresponding with the command frame of shaking hands is the status frames of shaking hands, when host computer after MCU sends the command frame of shaking hands, MCU should return the status frames of shaking hands to host computer.After host computer only received the status frames of shaking hands, whole communication process just can be proceeded, and host computer begins to carry out other data communication with MCU.Its frame structure is as shown in Figure 7.
Two, querying command frame and query State frame
The querying command frame is used for host computer and sends query requests, after MCU receives the querying command frame, corresponding information is encapsulated in the query State frame feeds back to host computer.
The querying command frame further comprises CU Domain (command frame is obtained in the frame tabulation), CU Call (call state querying command frame), CU Detail (details querying command frame), these four kinds of command frames of CU Stats (statistic behavior querying command frame); After MCU receives above-mentioned querying command frame; Feed back corresponding query State frame; Like CU Domain, CU Call, CU Detail, these four kinds of status frames of CU Stats, corresponding one by one with above-mentioned four kinds of querying command frames.
The frame structure of querying command frame is made up of frame head, information (I) and postamble three parts, and is as shown in Figure 5.Wherein, frame head is 14 bytes, and message part comprises fields such as order numbering, machine case number (CN), slot number, and postamble is 16 bytes.To different querying command frames, it is identical that its frame head and tail are divided, and message part utility command numbering is distinguished different querying command frames, for example; In this instance, utility command numbering 00,07; 08,09 represents CU Domain respectively, CU Call, CU Detail, CU Stats command frame.Machine case number (CN) field is used to identify the CU plate place machine case number (CN) that host computer will be inquired about, and machine case number (CN) field further is divided into two fields, the front two of [JX1] field identification machine case number (CN), back two of [JX2] field identification machine case number (CN).Slot number field [CW] is used to identify the slot number that host computer will be inquired about the CU plate.
When the querying command frame was CU Domain, machine case number (CN) field and slot number field all used designated character to fill like " FF ".When the querying command frame is when the state of the CU plate that is configured to MCU itself is inquired about, machine case number (CN) and slot number are filled with other designated characters, and for example [JX1] fills with " FF ", and [JX2] fills with " AB ", and slot number field [CW] is filled with " CD ".
After MCU receives the querying command frame, at first judge the type of command frame, the information of this CU plate is encapsulated in the query State frame of correspondence according to machine case number (CN) field and slot number field again and feeds back to host computer according to its order number field.
The query State frame comprises frame head, full line number, spare word joint number, machine case number (CN), slot number field and state information field.Wherein, The full line digital section is described the full line number of the state information that this query State frame comprises; The remainder bytes digital section is described the spare word joint number of the state information that this query State frame comprises, the machine case number (CN) and the slot number of the CU plate of this query State frame feedback of machine case number (CN) field and slot number field description.State information field comprises several full line state informations and remainder bytes information.The query State frame returns by row.After MCU receives the querying command frame, at first return first row of query State frame.First row comprises frame head, full line number, spare word joint number, machine case number (CN), slot number field.Other row (state information row) of query State frame obtain through the full line command frame, and the remainder bytes of state information obtains through the remainder bytes command frame.
