Just as, a GPRS module of a pair of monitoring devices is arranged in a link node, and a pair of first-in first-out buffers for transmission are correspondingly arranged respectively, the messages I, III and V of the temperature value in the drying machine body 1 are in the first-in first-out buffer area I for transmission, the messages II and IV of the temperature value in the drying machine body 1 are in the first-in first-out buffer area II for transmission, at this time, the message of the temperature value in the drying machine body 1 which is firstly constructed in the first-in first-out buffer area I for transmission is firstly identified as the message I of the temperature value in the drying machine body 1, the construction time point is two zero, one month of nine years and one day of nine points and eight minutes and twelve seconds, the message of the temperature value in the drying machine body 1 which is firstly constructed in the first-in first-out buffer area II for transmission is a message II of the temperature value in the drying machine body 1, and the construction time point is two zero, one nine years, ten months and one day for nine points, eight minutes and thirteen seconds; the preset time point can be a time point which is prior to the message construction time point of the temperature value in the random drying machine body 1, like two zero one nine-month-one-nine-point-nine-eighths-nineteen seconds, at this time, in the pair of first-in first-out buffer areas for transmission, the first message of the temperature value in the drying machine body 1 and the second message of the temperature value in the drying machine body 1 are respectively used for construction time point subtraction with the preset time point, nine and eleven time intervals are obtained, nine with the lowest time interval corresponds to the first-in first-out buffer area for transmission, and the first message with the temperature value in the drying machine body 1 with the first construction time point is the first message; the preset time point can also be a time point later than the message construction time point of the temperature value in the drying machine body 1, like two zero one nineteen months and nine eighths or six seconds a day, at this time, in the pair of first-in first-out buffer areas for transmission, the construction time points of the message one of the temperature value in the drying machine body 1 and the message two of the temperature value in the drying machine body 1 are respectively subtracted from the preset time point, the ABS value of the obtained subtraction result is used as a time interval, ten and nine pairs of time intervals are obtained, and the ten with the highest time interval corresponds to the first-in first-out buffer area one for transmission and contains the message one of the temperature value in the drying machine body 1 with the earliest construction time point.
And SA-2, configuring the position where the message of the temperature value in the drying machine body 1 meeting the preset condition is positioned by means of the time interval of each first-in first-out buffer area for transmission.
Here, when the time point set in advance in SA-1 is the time point later than the time point of constructing the message of the temperature value in the random drying machine body 1, when the GPRS modules of the plurality of monitoring devices perform transmission of the message of the temperature value in the drying machine body 1, the first-in first-out buffer area for transmission with a small time interval corresponds to the GPRS module of the monitoring device which is usually not low in transmission bandwidth, and the first-in first-out buffer area for transmission with a large time interval corresponds to the GPRS module of the monitoring device which is usually not low in transmission bandwidth.
The GPRS modules of five monitoring devices in the link node are set, and five first-in first-out buffers for transmission, namely, first, second, third, fourth and fifth, are correspondingly set respectively, and the corresponding time intervals of the five first-in first-out buffers for transmission are ten, twenty, thirty, forty and fifty in sequence, so that the bandwidths of the messages for transmitting the temperature values in the drying machine body 1 in the first-in first-out buffers for transmission, namely, the first, second, third, fourth and fifth, are sequentially the highest to the lowest.
At this time, further, the method of performing configuration on the place where the message of the temperature value in the drying machine body 1 meeting the preset condition is located can be: the message of the temperature value in the drying machine body 1 with the first-in first-out buffer area for transmission with the lowest message bandwidth for transmitting the temperature value in the drying machine body 1 is constructed into the first-in first-out buffer area for transmission with the highest message bandwidth for transmitting the temperature value in the drying machine body 1, so that the message of the temperature value in the drying machine body 1 is transmitted by replacing the first-in first-out buffer area for transmission with the lowest message bandwidth through the first-in first-out buffer area for transmission with the highest message bandwidth.
In addition, the method for performing configuration on the place where the message of the temperature value in the drying machine body 1 meeting the preset condition is located can also be as follows: the messages of temperature values in a pair or more than a pair of drying machine bodies 1 with earlier construction time points in the first-in first-out buffer zone E for transmission are configured into the first-in first-out buffer zone I for transmission, namely the messages of temperature values in the drying machine bodies 1 with the lowest bandwidth are configured into the first-in first-out buffer zone I for transmission, and the messages of temperature values in a plurality of drying machine bodies 1 with earlier construction time points are configured into the first-in first-out buffer zone I for transmission with the highest bandwidth for transmitting the messages of temperature values in the drying machine bodies 1, so that the fifth first-in first-out buffer zone I for transmission with the highest transmission bandwidth, which is replaced by the fifth first-in first-out buffer zone I for transmission with the lowest transmission bandwidth, is responsible for transmitting the messages of temperature values in a plurality of drying machine bodies 1.
In addition, the method of performing the configuration of the place where the message of the temperature value in the drying machine body 1 which meets the preset condition is located may be: the fourth FIFO buffer zone and the fifth FIFO buffer zone for transmission are determined to construct a message of the temperature value in the first or a plurality of drying machine bodies 1, and the message is configured to the first FIFO buffer zone and the second FIFO buffer zone for transmission in a balanced or random manner, namely, the message of the temperature value in the first drying machine body 1 with low bandwidth is configured to the first FIFO buffer zone for transmission, the message of the temperature value in the first drying machine body 1 with higher bandwidth is configured to the first FIFO buffer zone for transmission with higher bandwidth, so that the first FIFO buffer zone with low transmission bandwidth for transmission and the fourth FIFO buffer zone and the fifth FIFO buffer zone for transmission are responsible for the transmission of the message of the temperature value in the drying machine body 1.
And SA-3, the messages of the temperature values in the drying machine body 1 in the first-in first-out buffer area configured for transmission are serialized according to the construction time point.
Here, since the fifo buffer for transfer is a serialized buffer that receives the message of the temperature value in the drying machine body 1 from the end and transmits the message of the temperature value in the drying machine body 1 via the head, after the message of the temperature value in the drying machine body 1 in the fifo buffer for transfer is configured, the message of the temperature value in the drying machine body 1 that is to ensure the configuration time point is the first is transmitted the highest, and the message of the temperature value in the drying machine body 1 in the fifo buffer for transfer configured needs to be serialized according to the configuration time point; specifically, the messages of the temperature values in the drying machine body 1 can be serialized through a serialization algorithm of a pointer pointing address such as fast serialization, bubbling serialization, parallel serialization and the like.
The serialization method can be:
insertion serialization, i.e., inserting a record into an already ordered list, thus a new ordered list with the number of records increased by 1. The method uses double-layer circulation in the realization process, the outer layer circulation searches the position where the current element is to be inserted into the ordered list for all the elements except the first element, and the inner layer circulation searches the position where the current element is to be inserted into the ordered list and moves the ordered list.
SA-4, transferring the message of the temperature value in the drying machine body 1 by means of the serialized first-in first-out buffer for transfer.
Here, the messages of the temperature values in the drying machine body 1 from the first construction time point to the last construction time point are sequentially provided from the head to the end in the serialized first-in first-out buffer for transmission, and the messages of the temperature values in the drying machine body 1 are transmitted according to the serialized order, so that the information messages of the first construction time point can be efficiently transmitted.
The link characteristics are used, and the time interval of a first-in first-out buffer area which is corresponding to the GPRS module of each monitoring device and is used for transmission is initially determined; because more than one message of the temperature value in the drying machine body 1 is arranged in the first-in first-out buffer area for transmission, and each message of the temperature value in the drying machine body 1 corresponds to a construction time point, the time interval of the first-in first-out buffer area for transmission can be determined by the construction time point of the message of the temperature value in the drying machine body 1 in the first-in first-out buffer area for transmission; then, according to the time distance of each first-in first-out buffer area for transmission, the configuration is executed on the position where the message of the temperature value in the drying machine body 1 which meets the preset condition is located, and in the application, the GPRS module of the monitoring equipment with the higher transmission bandwidth and the GPRS module of the monitoring equipment with the lower transmission bandwidth can be distinguished according to the time distance, so that the configuration is executed on the position where the message of the temperature value in the drying machine body 1 which meets the preset condition is located according to the time distance of each first-in first-out buffer area for transmission, and the GPRS module of the monitoring equipment with the lower transmission bandwidth is replaced by the GPRS module of the monitoring equipment with the higher transmission bandwidth, which is equivalent to the situation that the GPRS module of the monitoring equipment with the lower transmission bandwidth is responsible for the transmission of the message of the temperature; because the messages of the temperature values in the drying machine body 1 are sent out from the head part in sequence, the messages of the temperature values in the drying machine body 1 in the configured first-in first-out buffer area for transmission are serialized according to the construction time point, then the messages of the temperature values in the drying machine body 1 are sent out from the first-in first-out buffer area for transmission by means of the serialized messages of the temperature values in the drying machine body 1, so that the messages of the temperature values in the drying machine body 1 can be sent out from the first-in first-out buffer area for transmission as soon as possible, the bandwidth of the messages of the temperature values in the drying machine body 1 in the first-in first-out buffer area for transmission of the GPRS module of each monitoring device is balanced, and the messages of the temperature values in the drying machine body 1 in the first-in first-out buffer area for transmission of the GPRS module of each monitoring device can be sent out sequentially and efficiently according to the construction, the transmission performance of the information message is greatly improved.
The method for transmitting the temperature value in the drying machine body 1 comprises the following steps:
TA-1, constructing more than one message of the temperature value in the drying machine body 1 by the temperature value in the drying machine body 1 on the link to be transmitted in advance, and sequentially setting the message of the temperature value in each drying machine body 1 from the head to the tail end in a first-in first-out buffer area which is used for transmitting and corresponds to the GPRS module of the plurality of monitoring equipment according to the sequence of the corresponding construction time point of the message of the temperature value in each drying machine body 1.
TA-2, determining the value obtained by subtracting the time point when the structure time point of the message of the temperature value in the drying machine body 1 at the head part in the first-in first-out buffer area for transmission is identical to the time distance of the first-in first-out buffer area for transmission.
Here, the messages of the temperature values in the drying machine body 1 are arranged in a sequence in the first-in first-out buffer areas for transmission, specifically, at the position where each first-in first-out buffer area for transmission is located from the head to the tail end, the messages of the temperature values in the drying machine body 1 are set in sequence according to the message construction timing of the temperature values in the drying machine body 1, so that the message of the temperature values in the drying machine body 1 at the head of each first-in first-out buffer area for transmission is the message of the temperature values in the drying machine body 1 at the head of the construction timing in the first-in first-out buffer areas for transmission, and is to be transmitted efficiently; in this case, the time interval of the fifo buffer for transfer can be used as the value obtained by subtracting the times at which the messages of the temperature values in the drying machine body 1 at the head of each fifo buffer for transfer are constructed at the same time.
Here, it is possible to perform the serialization in accordance with the construction timing sequence of the messages of the temperature values in the drying machine body 1 before the messages of the temperature values in the drying machine body 1 are set to each of the first-in first-out buffers for transmission, and specifically, after the messages of the temperature values in the drying machine body 1 allocated to each of the first-in first-out buffers for transmission are identified, the messages of the temperature values in the drying machine body 1 corresponding to each first-in first-out buffer area for transmission are serialized according to the sequence of the construction time points, then, the serialized messages of the temperature values in the drying machine body 1 are sequentially transmitted to corresponding first-in first-out buffer areas for transmission through the tail end according to the sequence from the first to the last of the construction time points, and the messages of the temperature values in the drying machine body 1 in each first-in first-out buffer area for transmission are sequentially arranged at the positions from the head to the tail end according to the sequence of the construction time points; the messages of the temperature values in the drying machine body 1 can also be randomly arranged in each first-in first-out buffer area for transmission, and then the messages of the temperature values in the drying machine body 1 in each first-in first-out buffer area for transmission are serialized according to the sequence of the construction time points, so that the messages of the temperature values in the drying machine body 1 in each first-in first-out buffer area for transmission are sequentially arranged at the positions from the head to the tail end according to the sequence of the construction time points.
Further, it is possible to use, as the time interval of the fifo buffer for transfer, a value obtained by subtracting the same time point immediately after the time point of construction of the message of the temperature value in the head dryer body 1 is obtained in each fifo buffer for transfer; the message of the temperature value in the drying machine body 1 is identified, so that the time point performance of the message construction of the temperature value in the drying machine body 1 is good; the constructed time points are directly identical, and the subtraction is executed, so that it is not necessary to separately set the execution time interval to obtain another preset time point, and the performance of identifying the time interval of each FIFO buffer for transmission can be improved.
TA-3, regarding the fifo buffer for transfer with the highest time interval as fifo buffer one for transfer, and regarding the message of the temperature value in the dryer body 1 of the head in the fifo buffer one for transfer as the target message.
Here, the first-in first-out buffer for transmission with the highest time interval is often a GPRS module of the monitoring device with the lowest transmission bandwidth, and the message of the temperature value in the head drying machine body 1 in the first-in first-out buffer for transmission is often a message of the temperature value in the drying machine body 1 with the first time point.
TA-4, the FIFO buffer for transfer with the lowest time interval is identified as FIFO buffer two for transfer.
Here, the second fifo buffer for transmission with the lowest time interval, which is the corresponding GPRS module of the monitoring device often with the highest transmission bandwidth, can take charge of more tasks of transmitting the messages of the temperature values in the dryer body 1, so as to improve the performance of transmitting the messages of the temperature values in the dryer body 1.
And TA-5, taking out the target message from the first buffer area and setting the target message into a second first-in first-out buffer area for transmission.
Here, the target message is a message for constructing the temperature value in the dryer body 1 at the earliest point in time, which is taken out through the first fifo buffer for transfer having the lowest transfer bandwidth and set in the second fifo buffer for transfer having the highest transfer bandwidth, and the transfer is performed through the second fifo buffer for transfer, so that the amount of the first fifo buffer for transfer can be effectively reduced, and the transfer performance of the message for the temperature value in the dryer body 1 can be improved.
Setting messages of temperature values in two pairs of drying machine bodies 1, namely one, three, five and seven pairs of messages of temperature values in the first-in first-out buffer area I for transmission at the beginning, and setting messages of temperature values in two pairs of drying machine bodies 1, four pairs of messages, six pairs of messages and eight pairs of messages of temperature values in the first-in first-out buffer area II for transmission; the first to the last of the messages of the temperature values in the drying machine body 1 are constructed sequentially, and after the transmission of one cycle, because the GPRS module of the corresponding monitoring equipment of the first-in first-out buffer area for transmission has a slow transmission bandwidth, the first-in first-out buffer area for transmission also has three, five and seven messages of the temperature values in the drying machine body 1; the second FIFO buffer area for transmission has high transmission bandwidth, only the eighth message of the temperature value in the drying machine body 1 remains in the second FIFO buffer area for transmission, at this time, the first FIFO buffer area for transmission with the highest time distance and the second FIFO buffer area for transmission with the lowest time distance can be obtained, the third message of the temperature value in the drying machine body 1 is configured into the second FIFO buffer area for transmission, the third message of the temperature value in the drying machine body 1 is transmitted through the second FIFO buffer area for transmission, the fifth message of the temperature value in the drying machine body 1 is synchronously transmitted, the fifth message of the temperature value in the drying machine body 1 is transmitted synchronously in the first FIFO buffer area for transmission, the long-time retention of the messages of the temperature value in the drying machine body 1 in the first FIFO buffer area for transmission due to low transmission bandwidth can be prevented, the transmission performance of the structure is not high.
TA-6, according to the time point, serializing the messages of the temperature value in the drying machine body 1 in the first-in first-out buffer zone configured for transmission.
TA-7, the message of the temperature value in the drying machine body 1 is transmitted by means of the first-in first-out buffer area for transmission after serialization.
And TA-8, when a new message of the temperature value in the drying machine body 1 needs to be transmitted, obtaining the message quantity of the temperature value in the drying machine body 1 in each first-in first-out buffer area for transmission.
TA-9, the newly added message of the temperature value in the drying machine body 1 is arranged in a first-in first-out buffer area for transmission with the minimum number of messages of the temperature value in the drying machine body 1.
Here, the number of the messages of the temperature value in the drying machine body 1 in the fifo buffer for transfer is not small, and is usually because the fifo buffer for transfer is slow in transfer, which causes the messages of the temperature value in the drying machine body 1 to be detained to a certain extent, and the number of the messages of the temperature value in the drying machine body 1 in the fifo buffer for transfer is the smallest, which indicates that the bandwidth of the fifo buffer for transfer is usually the highest, and when a message of a newly increased temperature value in the drying machine body 1 needs to be transferred, the fifo buffer for transfer having the smallest number of the messages of the temperature value in the drying machine body 1 is provided, which can sequentially transfer the messages of the newly increased temperature value in the drying machine body 1, and avoids the newly increased data packet from being provided after another fifo buffer for transfer which is slow in transfer, the performance of the message for transmitting the temperature value in the drying machine body 1 is further improved through the process of configuring the message from the first-in first-out buffer area for transmitting with the slower transmission speed to the first-in first-out buffer area for transmitting with the faster transmission bandwidth through the method.
Serving as a preferred scheme herein, a first process, a second process can be identified; here, the first process is configured to identify a time interval of a first-in first-out buffer for transmission corresponding to a GPRS module of each monitoring device; configuring the position where the message of the temperature value in the drying machine body 1 which meets the preset condition is located by means of the time interval of each first-in first-out buffer area for transmission; transmitting the message of the temperature value in the drying machine body 1 by means of a configured first-in first-out buffer area for transmission; the second process is used for obtaining the number of the messages of the temperature value in the drying machine body 1 in each first-in first-out buffer area for transmission when the message of the temperature value in the drying machine body 1 which is newly added needs to be transmitted; and setting the newly added messages of the temperature values in the drying machine body 1 in a first-in first-out buffer area for transmission with the least number of the messages of the temperature values in the drying machine body 1.
Here, it is possible to previously set a pair of independent first and second processes, the first process being configured with a message for configuring a temperature value in the drying machine body 1 in each fifo buffer for transfer by calculation, the second process being configured with a message for processing a temperature value in the newly added drying machine body 1, and the first and second processes being further capable of performing control via a process lock so as to avoid a collision of the first and second processes during operation.
The pair of processes is set in advance, the first process and the second process are separated, the process lock can be set to avoid conflict between the first process and the second process, and the performance of transmitting the message of the temperature value in the drying machine body 1 can be further improved.
It can be understood that after the newly added message of the temperature value in the drying machine body 1 is set in the corresponding fifo buffer for transfer, each fifo buffer for transfer can cyclically execute the methods of step 602 to step 609 to complete the transfer of the message of the temperature value in the drying machine body 1.
