In addition, the present application addresses the operation of pipeline PIPE: the incoming end address and the outgoing end address are dynamically changed structures relative to each other.
Under specific application, a transmission unit for receiving an information instruction transmits a sequence code and a corresponding blank information message to a controller in an information acquisition device through a transmission processing unit, the controller in the information acquisition device fills equipment operation state information of a sewage sludge treatment field, the sequence code, the total byte quantity of an effective information message corresponding to the sequence code and the serial number of the last byte of the effective information message in the blank information message, and returns the information message to a remote information monitoring device in the format of the information message after filling is finished, and the information is received by an information receiving unit.
Preferably, the management unit manages the remaining valid information packet by comparing the forwarding end address with the fetching end address, and sets in advance a maximum threshold value at which y is the remaining valid information packet, and when the value of { forwarding end address-fetching end address } is not lower than { x +1-y }, that is: when the residual information area capable of storing information is not lower than the highest threshold value of the residual effective information message, informing a transmission unit for receiving an information instruction to terminate transmitting the information message; when the value of { transfer end address-fetch end address } is lower than { x +1-y }, that is: and when the residual information area capable of storing information is lower than the highest threshold value of the residual effective information message, informing the transmission unit receiving the information instruction to start transmitting the information message. The throughput management during serialization is achieved by managing the operation of the transfer message of the transfer unit receiving the message instruction.
The management unit receives the transmission ending address returned by the information receiving unit, and achieves the taking-out management of the information taking-out unit according to the transmission ending address of the effective information message corresponding to the sequence code.
Specifically, after the information receiving unit receives the valid information packet corresponding to a sequence code, the management unit stores the transfer end address of the valid information packet corresponding to the sequence code, and then the management unit allows the information retrieving unit to perform the sequential retrieval according to the received sequence code and the total byte amount information of the valid information packet corresponding to the sequence code. That is, under the taking out management of the management unit, the information taking out unit only takes out the effective information message corresponding to the received serial code, thereby reducing the useless taking out operation work which is not good for part and improving the taking out performance.
According to the application, the byte quantity received by the effective information message is set to be z in advance, the byte quantity of the information area of the effective information message corresponding to each sequence code by the pipeline PIPE is z, the number of the information areas is more than x +1, and the byte quantity of the information area of the pipeline PIPE is more than { x +1} × z;
preferably, the byte amount of the information area capable of storing information remaining in the PIPE is not less than the byte amount of the valid information packet temporarily stored in the controller in the transfer processing unit and the information acquisition device, that is, the following conditions are met:
the value of { x +1} × z- { transfer end address-fetch end address } is not lower than the value of y × z.
In addition, the running state information of the equipment on the sewage and sludge treatment site is required to be not lost, and the following requirements are met: the byte quantity of the information area which can store information and is left in the pipeline PIPE is higher than the byte quantity of the effective information message temporarily stored in the controller in the transmission processing unit and the information acquisition device; that is, the byte amount of the residual information area capable of storing information in the PIPE is higher than the effective information message which is not retrieved; therefore, in case that the valid message corresponding to a sequence code is not completely received, the pipeline PIPE PIPE can keep enough residual information area capable of storing information in advance to accommodate all information, and the effect of achieving information serialization without losing data under special conditions is achieved.
Preferably, the byte amount of the valid information packet stored in the information area of the pipeline PIPE is not higher than the byte amount of the valid information packet corresponding to { x +1-y } sequence codes, and the operation mode is as follows:
the equation: { x +1 }. times.z- { transfer end address-fetch end address }. times.z ≧ y × z, the respective elimination of z becomes the equation: { x +1} - { transmission ending address-taking ending address } - [ y ] or more;
the equation: { x +1} - { transfer end address-fetch end address } > gty perform a right shift operation to become an equation: { forwarding end address-fetching end address } ≦ { x +1-y }, where { forwarding end address-fetching end address } represents the amount of information bytes that the information area of the PIPE has saved.
For example, the value of { x +1} is set in advance to 24(ii) a The byte quantity received by the effective information message is set as z in advance, and the value of z is 29；
The value of the highest threshold value y for transmitting the effective information message remained in the controller in the processing unit and the information acquisition device is 23；
By feeding such values into the above equation, one can obtain:
{ transfer end address-fetch end address } × 29 ≤24×29-23×29；
Thus, it can be obtained: { transfer end address-fetch end address } × 29 ≤23×29；
Thus, it can be obtained: { forwarding end address-fetching end address } < 23；
Thereby obtaining: { forwarding end address-fetching end address } < 23Can derive: the information area of the pipeline PIPE is used for storing information with byte amount not higher than 23The byte size of the valid information message corresponding to each sequence code.
