A drying method for a vacuum dryer, comprising:

In addition, in order to realize the remote monitoring of the temperature value in the drying body 1 by each department, the controller will be connected to a wireless communication module such as a GPRS module, and the controllers of the various departments in the GPRS network, such as A monitoring device such as a notebook computer with a GPRS module is wirelessly connected, so that the controller can transmit the obtained temperature value in the drying body 1 to the monitoring device for display, so as to achieve the purpose of monitoring, and use several When the GPRS module of the monitoring device transmits the temperature value in the drying body 1, the temperature value in the drying body 1 to be transmitted is initially allocated to the GPRS module of each monitoring device, and the GPRS module of each monitoring device The received message of the temperature value in the drying body 1 is transmitted to the monitoring device. After the monitoring device receives the message of the temperature value in the drying body 1, the message of the temperature value in the drying body 1 is processed according to the following: Serialization is performed successively at time points, and finally the serialized message of the temperature value in the drying body 1 is displayed or processed.

When the GPRS module of the monitoring device transmits the message of the temperature value in the drying body 1 to the monitoring device, because the transmission bandwidth of the GPRS module of each monitoring device is often inconsistent, the transmission of the GPRS module of some monitoring devices will occur. With low bandwidth, the GPRS module of some monitoring equipment transmits the status of high bandwidth; the GPRS module of the monitoring equipment with high bandwidth transmits the message of the temperature value in the drying body 1 to the monitoring equipment efficiently, and transmits the message of the monitoring equipment with low bandwidth. The message of the temperature value in the drying body 1 transmitted by the GPRS module will be stopped in the GPRS module of the monitoring device within a large time range, and the monitoring device will only receive the message of the temperature value in the drying body 1 continuously. The message can be processed smoothly under the condition of 1. Therefore, because the GPRS module of some monitoring devices has a low transmission bandwidth, after the message of the temperature value in the drying body 1 of the GPRS module of another monitoring device is transmitted to the monitoring device, It can only wait to transmit the message of the temperature value in the drying body 1 of the GPRS module of the monitoring device with low bandwidth, which is not conducive to the improvement of the transmission performance.

Modules running on the controller, including:

Identifying module, for identifying the time distance of the FIFO buffer corresponding to the GPRS module of each described monitoring device for delivery;

a configuration module, configured to perform configuration on the location of the message with the temperature value in the drying body 1 that meets the pre-set conditions by virtue of the time interval of each of the FIFO buffers used for delivery;

The serialization module is used to serialize the message of the temperature value in the drying body 1 in the first-in-first-out buffer that is configured for delivery according to the point of construction;

The delivery module is configured to deliver the message of the temperature value in the drying body 1 by means of the serialized FIFO buffer for delivery.

The method for transferring the temperature value in the drying body 1 includes:

A monitoring device that receives the transmitted temperature value in the drying body 1 and performs analysis and converts the temperature value in the drying body 1 into a current signal;

The method for transferring the temperature value in the drying body 1 includes the following procedures:

SA-1, identify the time interval of the FIFO buffer used for delivery corresponding to the GPRS module of each of the monitoring equipment; here, the FIFO buffer used for delivery is provided with more than one drying body For the message of the temperature value in 1, each message of the temperature value in the drying body 1 has a corresponding construction time point.

Here, the message of the temperature value in the drying body 1 can be a message of the temperature value in the drying body 1; in detail, in the link, when the temperature value in the drying body 1 needs to be transmitted , because the temperature value in the drying body 1 is generally not small, the temperature value in the drying body 1 is often constructed into several packets of the temperature value in the drying body 1, and then the transmission is continued.

Here, when the message of the temperature value in each dryer body 1 is constructed, there will be a corresponding construction time point, just like, the temperature value in the dryer body 1 on the link is constructed into five dryers When the message of the temperature value in the body 1, the message 1 of the temperature value in the drying body 1, the message 2 of the temperature value in the drying body 1, the message 3 of the temperature value in the drying body 1 , Message 4 of the temperature value in the drying body 1, Message 5 of the temperature value in the drying body 1 The construction time points can be respectively: 9:8:12 on October 1, 2019 , 9:8:13 on October 1, 2019, 9:8:14 on October 1, 2019, 9:8:15 on October 1, 2019 seconds, 9:8:16 on October 1, 2019.

Here, the GPRS module of each monitoring device in the link node is correspondingly provided with a first-in, first-out buffer for transmission. The messages of the temperature values in the drying body 1 are respectively set in inconsistent FIFO buffers for transmission.

Here, the time interval of the corresponding FIFO buffer for delivery of the GPRS module of each monitoring device can be determined by the following method: obtaining each FIFO buffer for delivery respectively. At the construction time point of the message of the temperature value in each drying body 1, select the structure of the message of the temperature value in the drying body 1 constructed first in each FIFO buffer for transmission. time point, perform a subtraction operation between each construction time point and the pre-set time point, and the difference obtained is the time interval applied to the passed FIFO buffer.

For example, it is assumed that there is a pair of GPRS modules for monitoring equipment in the link node, and a pair of first-in-first-out buffers for transmission are correspondingly set up respectively. In the first-in, first-out buffer 1 for delivery, the message 2 and 4 of the temperature value in the drying body 1 are in the FIFO buffer 2 for delivery. At this time, the FIFO for delivery is identified first. The message of the temperature value in the drying body 1 first constructed in the buffer zone 1 is the message 1 of the temperature value in the drying body 1, and the construction time is 9:80 on October 1, 2019 Twelve seconds, the message of the temperature value in the drying body 1 constructed first in the first-in-first-out buffer 2 for transmission is the message of the temperature value in the drying body 1, and the construction time point is 20 9:8:30 on October 1, 1999; the preset time point can be a time point prior to the message construction time point of the temperature value in the arbitrary drying body 1, as At 9:8:19 on October 1, 2019, at this time, in the pair of FIFO buffers used for transmission,

messages

1 and 1 of the temperature value in the drying body 1 are used respectively. The construction time point of the message 2 of the temperature value in the drying body 1 is subtracted from the pre-set time point, and nine and eleven pairs of time intervals are obtained. Buffer 1, message 1 with the temperature value in the drying body 1 at the earliest construction time point; the preset time point can also be a message later than the temperature value in the drying body 1 At one point in the construction time point, like 9:8:06 on October 1, 2019, at this time, the pair of FIFO buffers used for transfer are respectively used in the drying machine 1. The construction time point of the message 1 of the temperature value of the drying machine 1 and the message 2 of the temperature value in the drying body 1 is subtracted from the preset time point, and the ABS value of the obtained subtraction result is used as the time distance, and ten There are nine pairs of time intervals, and the tenth with the highest time interval corresponds to the first-in-first-out buffer 1 for transmission, which contains the message 1 of the temperature value in the drying body 1 at the first construction point.

SA-2, by virtue of the time interval of each of the FIFO buffers for delivery, configures the location of the message where the temperature value in the drying body 1 meets the pre-set condition.

Here, the pre-set time point in SA-1 is used as the time point later than the message construction time point of the temperature value in the random drying body 1. When the GPRS modules of several monitoring equipments are used for the drying body When the message with the temperature value within 1 is transmitted, the FIFO buffer used for transmission with a small time gap is often the GPRS module of the monitoring device with a low transmission bandwidth. Correspondingly, the large time gap is used for the transmission. The corresponding FIFO buffer is often the GPRS module of the monitoring device with low transmission bandwidth.

It is set that there are five GPRS modules for monitoring equipment in the link node, and there are five FIFO buffers one, two, three, four, and five for transmission respectively, and the five are used for transmission. The corresponding time intervals of exiting the buffer zone are ten, twenty, thirty, forty, and fifty in sequence, and it can be considered that the first-in-first-out buffer zone one, two, three, four, and five for transfer transfer into the drying body 1 The bandwidth of the packets with the temperature value is the highest to the lowest.

At this time, further, the method for configuring the location of the message with the temperature value in the drying body 1 that meets the pre-set conditions can be as follows: the bandwidth of the message transmitting the temperature value in the drying body 1 is the lowest. The first-in-first-out buffer used to transmit the message of the temperature value in the first drying machine 1 at the time of construction, and the message with the highest bandwidth configured to transmit the temperature value in the drying machine 1 is used for The first-in, first-out buffer for delivery with the highest delivery bandwidth is replaced by the FIFO buffer with the lowest delivery bandwidth for delivery. Transmission of the message of the temperature value.

In addition, the method for configuring the location of the message with the temperature value in the drying body 1 that meets the pre-set conditions can also be as follows: the first-in-first-out buffer E used for transmission is configured at an earlier time point. For or more than one pair of temperature value messages in the drying body 1, configure the first-in, first-out buffer 1 for transmission, that is, the message bandwidth that transmits the temperature value in the drying body 1 is the lowest. In the first-in-first-out buffer used for transmission, the messages with the temperature values in the drying machine 1 earlier in construction time are allocated to the message with the highest bandwidth for transmitting the temperature value in the drying machine 1. The first-in-first-out buffer is used to achieve the first-in-first-out buffer for delivery with the highest delivery bandwidth. The first-in-first-out buffer for delivery with the lowest delivery bandwidth is replaced. transmission of text.

In addition, the method for configuring the location of the message with the temperature value in the drying body 1 that meets the pre-set conditions can also be: identifying the first-in-first-out buffer used for transmission, the four- or five-mile structure is earlier. One or several messages of the temperature value in the drying body 1 are evenly or randomly allocated to the first-in, first-out

buffer

1 or 2 for transmission, that is, the message that transmits the temperature value in the drying body 1 In a number of FIFO buffers for transmission with low bandwidth, the packets with the temperature value in the dryer body 1 earlier in construction time are configured to transmit the temperature value in the dryer body 1 with a higher bandwidth. A number of high FIFO buffers for delivery to achieve a FIFO buffer with higher delivery bandwidth for

delivery

1, 2 Replace the FIFO buffer with low delivery bandwidth for delivery 4. The fifth is responsible for the transmission of messages of temperature values in several drying bodies 1 .

SA-3, perform serialization on the message of the temperature value in the drying body 1 in the configured FIFO buffer for delivery according to the construction time point.

Here, because the FIFO buffer used for transmission is a serialized buffer that receives the message of the temperature value in the drying body 1 from the end, and transmits the message of the temperature value in the drying body 1 through the header, After configuring the message of the temperature value in the drying body 1 in the FIFO buffer for transmission, it is necessary to ensure that the message of the temperature value in the drying body 1 at the first construction point is transmitted at the highest level. Out, the message of the temperature value in the drying body 1 in the configured FIFO buffer for transmission must be serialized according to the construction time; The serialization algorithm whose pointer points to the address such as serialization performs serialization on the message of the temperature value in the drying body 1 .

Serialization methods can be:

Insert serialization, that is, inserting a record into an already sorted sorted table, resulting in a new sorted table with the number of records increased by 1. In its implementation process, a double-layer loop is used. The outer loop searches all elements except the first element, and the inner loop searches the ordered table in front of the current element to find the place to be inserted, and moves it.

SA-4, transmits the message of the temperature value in the drying body 1 by means of the serialized FIFO buffer for transmission.

Here, in the serialized first-in-first-out buffer for delivery, from the head to the end are sequentially provided with the message of the temperature value in the drying body 1 from the first construction time point to the last construction time point, according to The serialized order transmits the message of the temperature value in the drying body 1, which can achieve the efficient transmission of the information message with the first construction time point.

Using the characteristics of the link here, it is initially determined that the GPRS module of each monitoring device corresponds to the time interval of the FIFO buffer for delivery; because there are more than one drying body 1 in the FIFO buffer for delivery. The message of the temperature value in each drying machine 1 has a corresponding construction time point. Therefore, the temperature value in the drying machine 1 can be determined by means of the first-in-first-out buffer used for transmission. The construction time point of the message identifies the time interval of the FIFO buffer used for delivery; then, according to the time interval of each FIFO buffer used for delivery, the dryer that meets the pre-set conditions is determined. The configuration is performed at the location where the message of the temperature value in body 1 is located. In operation, the GPRS module of the monitoring device with faster transmission bandwidth and the GPRS module of the monitoring device with slower transmission bandwidth can be distinguished by the time distance. Therefore, By virtue of the time interval of each of the first-in-first-out buffers used for transmission, the configuration is performed on the location of the message with the temperature value in the drying body 1 that meets the pre-set conditions, which is equivalent to the transmission bandwidth is faster. The GPRS module of the monitoring device is replaced by the GPRS module of the monitoring device with a slower transmission bandwidth, which is responsible for the transmission of some messages of the temperature value in the drying body 1; The message of the temperature value in the drying body 1 is sent out in sequence, so according to the construction time point, after performing the serialization of the message of the temperature value in the drying body 1 in the first-in-first-out buffer for delivery after configuration, By means of the serialized FIFO buffer for transmission, the message of the temperature value in the drying body 1 can be transmitted, so that the configured message of the temperature value in the drying body 1 can be transferred from the FIFO for transmission as soon as possible. It is sent out in the first-out buffer, so as to balance the bandwidth of the first-in-first-out buffer used by the GPRS module of each monitoring device to transmit the message of the temperature value in the drying body 1, so that the GPRS module of each monitoring device can The message of the temperature value in the drying body 1 in the FIFO buffer used for transmission can be efficiently transmitted in sequence according to the construction time point, which greatly improves the transmission performance of the information message.

TA-1, based on the temperature value in the drying body 1 on the link to be transmitted, constructs more than one message of the temperature value in the drying body 1 in advance, and according to the temperature in each drying body 1 The sequence of the corresponding construction time points of the message of the value, in the FIFO buffer corresponding to the GPRS module of the several monitoring devices for transmission, each of the drying fuselage 1 is set in sequence from the head to the end. The temperature value within the telegram.

TA-2, the value obtained by subtracting the construction time point of the message of the temperature value in the drying body 1 at the head in the first-in-first-out buffer for delivery and the current time point is identified as the above-mentioned value. The time interval of the FIFO buffer used for delivery.

Here, the message of the temperature value in the drying body 1 is serialized in the FIFO buffer for delivery, specifically, from the head to the end of each FIFO buffer for delivery where the message of the temperature value in the drying body 1 is located, the corresponding message of the temperature value in the drying body 1 is set in sequence according to the time point of the message construction of the temperature value in the drying body 1. Therefore, each FIFO buffer used for transmission is The message of the temperature value in the drying body 1 at the head of the zone is the message of the temperature value in the drying body 1 at the head of the construction time point in the FIFO buffer for delivery, and it must be efficiently Outgoing; at this time, it is only necessary to perform the subtraction of the construction time point of the message of the temperature value in the drying body 1 in the header of each FIFO buffer used for transmission with the current time point, and the obtained value is The time gap that can act as this FIFO buffer for delivery.

Here, before setting the message of the temperature value in the drying body 1 to each FIFO buffer for delivery, it can be executed according to the time-sequence of the construction of the message of the temperature value in the drying body 1 Serialization, specifically, after identifying the message of the temperature value in the drying body 1 configured for each FIFO buffer for delivery, firstly assign each FIFO buffer for delivery respectively. The message of the temperature value in the drying body 1 is serialized according to the sequence of the construction time point, and then the serialized message of the temperature value in the drying body 1 is sequenced from the first to the last according to the construction time point. It is sequentially passed through the end to the corresponding FIFO buffer for delivery, so that the message of the temperature value in the drying body 1 in each FIFO buffer for delivery is in the order of the construction time point. It is set from the head to the end; it is also possible to arbitrarily set the message of the temperature value in the drying body 1 to each FIFO buffer for delivery, after each FIFO for delivery. In the first-out buffer, the message of the temperature value in the drying body 1 is serialized according to the order of the construction time point, so that the temperature value in the drying body 1 in each FIFO buffer used for transmission is serialized. The message is set from the head to the end according to the order of construction time point.

Here, further, it is possible to directly obtain the value obtained by subtracting the current time point after the construction time point of the message for obtaining the temperature value in the head drying body 1 in each FIFO buffer for transmission. The time interval that acts as the first-in-first-out buffer for delivery; because the location of the message of the obtained temperature value in the drying body 1 is identified, so the message construction of the temperature value in the drying body 1 is obtained. The performance of the point is good; the construction time point is directly subtracted from the current time point execution, so there is no need to set the execution time interval to obtain another pre-set time point, which can improve the identification of each FIFO buffer used for delivery. time zone performance.

TA-3, identify the first-in, first-out buffer for delivery with the highest time interval as the first-in-first-out buffer for delivery, and place the first-in, first-out buffer for delivery at the head The message of the temperature value inside the drying body 1 is identified as the target message.

Here, the FIFO buffer 1 for delivery with the highest time distance corresponds to the GPRS module of the monitoring device with the lowest delivery bandwidth, and the FIFO buffer 1 for delivery is located in the dryer at the head. The message of the temperature value in the body 1 is often the message of the temperature value in the body 1 which is first dried at the time of construction.

TA-4, identify the FIFO buffer for delivery with the lowest time interval as the FIFO buffer 2 for delivery.

Here, the first-in-first-out buffer 2 with the lowest time distance is used for transmission, and the corresponding GPRS module is often the monitoring device with the highest transmission bandwidth, which can be responsible for more tasks of transmitting the message of the temperature value in the drying body 1 , to improve the performance of the message that transmits the temperature value in the drying body 1 .

TA-5, take out the target message through the buffer 1 and set it into the first-in-first-out buffer 2 for delivery.

Here, the target message is the message of the temperature value in the drying body 1 at the first construction point, and it is taken out from the FIFO buffer 1 for delivery with the lowest delivery bandwidth, and is set to the highest delivery bandwidth. In the FIFO buffer 2 for delivery, the delivery is performed through the FIFO buffer 2 for delivery, which can effectively reduce the amount of FIFO buffer 1 used for delivery, and improve the air quality in the drying body 1. The transmission performance of the message with the temperature value.

The first-in-first-out buffer 1 for transmission is initially configured with one, three, five, and seven pairs of temperature values in the drying body 1, and the first-in, first-out buffer 2 for transmission is configured with Two, four, six and eight pairs of messages of the temperature value in the drying body 1; the construction time points of the messages 1 to 8 of the temperature value in the drying body 1 are sequentially from the first to the last, and after a cycle of transmission , because the first-in-first-out buffer used for delivery 1 corresponds to the GPRS module of the monitoring device, the transmission bandwidth is relatively slow, and there are three, five, and seven in the FIFO buffer 1 used for delivery. The message of the temperature value; while the FIFO buffer 2 used for transmission has a high transmission bandwidth, and there is only a message 8 of the temperature value in the drying body 1 left in the FIFO buffer 2 used for transmission. When the time interval is the highest, the first-in-first-out buffer 1 for transmission is the one with the highest time interval, and the first-in-first-out buffer 2 for transmission is the one with the smallest time interval. Configure the message 3 of the temperature value in the drying body 1 To the FIFO buffer 2 for delivery, the message of the temperature value in the drying body 1 is delivered via the FIFO buffer 2 for delivery 3, synchronous, FIFO buffer for delivery Once the message 5 of the temperature value in the drying body 1 is transmitted, the messages 3 and 5 of the temperature value in the drying body 1 are transmitted synchronously, which can prevent the FIFO buffer for transmission due to the low transmission bandwidth. The message of the temperature value in the drying body 1 stays for a long time, which constitutes a situation that the transmission performance is not high.

TA-6, according to the construction time point, serialize the message of the temperature value in the drying body 1 in the first-in-first-out buffer that is configured for delivery.

TA-7 transmits the message of the temperature value in the drying fuselage 1 by means of the serialized FIFO buffer for transmission.

TA-8, when there is a new message of the temperature value in the drying body 1 to be transmitted, obtain each message of the temperature value in the drying body 1 in the FIFO buffer for transmission. quantity.

TA-9, set the newly added message of the temperature value in the drying body 1 in the first-in, first-out buffer for transmission with the smallest number of the message of the temperature value in the drying body 1 .

Here, in the FIFO buffer used for transmission, there are a lot of messages about the temperature value in the drying body 1, which is often because the FIFO buffer used for transmission is slow in transmission, resulting in the drying body 1 The message of the temperature value in the dryer is retained to a certain extent, and the number of messages of the temperature value in the drying body 1 is the least in the FIFO buffer used for transmission. The transmission bandwidth is often the highest. When there is a new message with the temperature value in the drying body 1 to be transmitted, it is set to the first-in-first-order transmission with the smallest number of messages with the temperature value in the drying body 1. The output buffer, the first-in-first-out buffer used for transmission can sequentially transmit the newly added message of the temperature value in the drying body 1, which avoids setting the newly added data packet in other applications with slower transmission. After the FIFO buffer is transmitted, the process of configuring it from the FIFO buffer for delivery with slower delivery to the FIFO buffer with faster delivery bandwidth through the above method, and further Improves the performance of the message that transmits the temperature value in the dryer body 1.

As a preferred solution here, the first process and the second process can be identified; here, the first process is used to identify the time of the FIFO buffer corresponding to the GPRS module of each monitoring device for delivery. distance; by virtue of the time distance of each of the first-in-first-out buffers used for delivery, configure the location where the message of the temperature value in the drying body 1 meets the pre-set conditions; The transmitted FIFO buffer transmits the message of the temperature value in the drying body 1; the second process is used to obtain each message when the newly added message of the temperature value in the drying body 1 needs to be transmitted. The number of messages of the temperature value in the drying body 1 in the FIFO buffer for transmission; the newly added message of the temperature value in the drying body 1 is set in the drying body 1 The first-in-first-out buffer for delivery with the smallest number of temperature values in the message.

Here, a pair of independent first process and second process can be set in advance, the first process configures the message of the temperature value in the drying body 1 in each FIFO buffer for delivery via calculation, The second process is used to process the configuration of the newly added temperature value message in the drying body 1. The first process and the second process can also execute control through the process lock to avoid the first process and the second process during the operation process. conflict occurred.

Here, a pair of processes are set in advance, the functions of the first process and the second process are separated, and the process lock can be set to avoid conflicts between the first process and the second process, which can further improve the transmission of the temperature value in the drying body 1. Packet performance.

It can be understood that after the newly added message of the temperature value in the drying body 1 is set in the corresponding FIFO buffer for delivery, each FIFO buffer for delivery can cyclically execute step 602 Go to the method of step 609 to complete the transmission of the message of the temperature value in the drying body 1 .

Using the characteristics of the link here, first determine the time interval of the FIFO buffer used for transmission corresponding to the GPRS module of each monitoring device; because there are more than one drying body 1 in the FIFO buffer used for transmission The message of the temperature value in each drying machine 1 has a corresponding construction time point. Therefore, the temperature value in the drying machine 1 can be determined by means of the first-in-first-out buffer used for transmission. The construction time point of the message identifies the time interval of the FIFO buffer used for delivery; then, according to the time interval of each FIFO buffer used for delivery, the dryer that meets the pre-set conditions is determined. The configuration is performed at the location where the message of the temperature value in body 1 is located. In actual application, the GPRS module of the monitoring device with faster transmission bandwidth and the GPRS module of the monitoring device with slower transmission bandwidth can be distinguished by the time distance. Therefore, By virtue of the time interval of each of the first-in-first-out buffers used for transmission, the configuration is performed on the location of the message with the temperature value in the drying body 1 that meets the pre-set conditions, which is equivalent to the transmission bandwidth is faster. The GPRS module of the monitoring device is replaced by the GPRS module of the monitoring device with a slower transmission bandwidth, which is responsible for the transmission of some messages of the temperature value in the drying body 1; The message of the temperature value in the drying body 1 is sent out in sequence, so according to the construction time point, after performing the serialization of the message of the temperature value in the drying body 1 in the first-in-first-out buffer for delivery after configuration, By means of the serialized FIFO buffer for transmission, the message of the temperature value in the drying body 1 can be transmitted, so that the configured message of the temperature value in the drying body 1 can be transferred from the FIFO for transmission as soon as possible. It is sent out in the first-out buffer, thereby balancing the bandwidth of the first-in-first-out buffer used by the GPRS module of each monitoring device to transmit the message of the temperature value in the drying body 1, so that the GPRS module of each monitoring device uses The message of the temperature value in the drying body 1 in the transmitted FIFO buffer can be quickly sent out in sequence according to the construction time point, which greatly improves the data transmission performance.

The present invention uses the characteristics of the link to first determine the time interval of the FIFO buffer used for transmission corresponding to the GPRS module of each monitoring device; because there are more than one drying body in the FIFO buffer used for transmission The message of the temperature value in 1, the message of the temperature value in each drying body 1 has a corresponding construction time point, so the temperature value in the drying body 1 in the first-in-first-out buffer for transmission can be used. The time interval of the first-in, first-out buffer for delivery is determined at the construction time point of the message; then, according to the time interval of each of the FIFO buffers for delivery, the drying conditions that meet the pre-set conditions are determined. The configuration is performed at the location where the message of the temperature value in the fuselage 1 is located. In actual application, the GPRS module of the monitoring device with a faster transmission bandwidth and the GPRS module of the monitoring device with a slower transmission bandwidth can be distinguished by the time distance. Therefore, , by virtue of the time interval of each of the FIFO buffers used for delivery, the configuration is performed on the location of the message with the temperature value in the drying body 1 that meets the pre-set conditions, which is equivalent to a faster delivery bandwidth. The GPRS module of the monitoring equipment is replaced with the GPRS module of the monitoring equipment with a slower transmission bandwidth. The message of the temperature value in the drying body 1 is sent out in sequence, so the message of the temperature value in the drying body 1 in the configured FIFO buffer for delivery is serialized according to the construction time point. , the message of the temperature value in the drying body 1 can be transmitted by means of the serialized FIFO buffer for transmission, so that the message of the temperature value in the configured drying body 1 can be transmitted from the It is sent out in the first-in, first-out buffer, thereby balancing the bandwidth of the first-in, first-out buffer used by the GPRS module of each monitoring device to transmit the message of the temperature value in the drying body 1, so that the GPRS module of each monitoring device can The message of the temperature value in the drying body 1 in the FIFO buffer used for transmission can be quickly sent out sequentially according to the construction time point, which greatly improves the transmission performance of the message of the temperature value in the drying body 1 . It is effectively avoided that the transmission bandwidth of the GPRS modules of some monitoring equipments in the prior art is low, so that the message of the temperature value in the drying body 1 of the GPRS modules of other monitoring equipments can only wait for the transmission bandwidth to be low after being transmitted to the monitoring equipment. The temperature value message in the drying body 1 of the GPRS module of the monitoring device is not conducive to the improvement of the transmission performance.
