Therefore, air pressure control is very important for bio-safe clean rooms, buffer rooms, sample receiving rooms or sample preparation rooms.
While the development of internet of things technology requires that the monitoring of the air pressure in an environment such as a bio-safe clean room, a buffer room, a sample receiving room or a sample preparation room be performed in a movable and off-site manner, there is no platform and method for performing the monitoring of the air pressure in an environment such as a bio-safe clean room, a buffer room, a sample receiving room or a sample preparation room in a movable and off-site manner.
The wireless information transmission mode is a main mode for executing information transmission among threads used for monitoring the air pressure, and the method ensures that the information transmission among the threads is on time and reliable under the condition of long time, which is very critical for the whole platform.
Currently, information transfer between threads is generally executed by using a one-side transmission mode of a foreground and a background or two-side transmission modes of the foreground and the background; specifically, one side of the foreground and the background is most easily transmitted, the most common mode is used, the foreground is automatically linked with the background structure to transmit information such as air pressure values and other response messages, the background receives and processes the air pressure value information and then feeds the air pressure value information back to the foreground to process the response, and then information transmission is stopped; because of the one-side transmission, the background cannot automatically transmit information to the foreground, and the foreground cannot grasp a plurality of feedback responses of the background, like grasping response values of each stage of background treatment.
The transmission mode of the foreground and the background is an improved mode, and is also automatically linked with the background structure through the foreground, the foreground and the background can automatically transmit information during the linking period, however, because the linked information can be automatically transmitted through the foreground, the foreground needs to execute other timing and background transmission detection information to ensure that the link is free of obstacles, and once the detection information is lost, the foreground needs to be linked with the background structure again; if the background is to automatically transfer information, the background is to additionally handle the information to avoid information loss.

the step 6 specifically includes:
when the controller transmits information to the smart phone, the controller is used as a foreground of a transmitting party, and the smart phone is used as a background of a receiving party; when the smart phone transmits information to the controller, the smart phone is the foreground of the transmitting party, the controller is the background of the receiving party, the smart phone and the controller can be used as the foreground of the transmitting party and the background of the receiving party in turn, the transmitting party and the receiving party all need to run a task detection thread to execute task link detection, and the following specific description is carried out on the transmission modes of the two sides:
step 6-1: after receiving the link message I transmitted by the foreground, the background constructs a wireless link I with the foreground;
if the transmitter wants to transmit the link message, it connects with the detecting thread of the receiver to execute the link construction, at this time, the transmitter is foreground, and the receiver is background.
Step 6-2: the background receives the information transmitted by the foreground through a wireless link I;
after the wireless link is constructed, the transferor transfers the information to the recipient.
Step 6-3: during the period of receiving the information transmitted by the foreground at the background, if the background needs to transmit the information to the foreground and detects that the first wireless link is cancelled, the background transmits a second link message to the foreground, and the second wireless link message is constructed with the foreground;
after the transmitting party and the receiving party are linked, the transmitting party and the receiving party perform information transmission by using the existing two-side transmission mode of the foreground and the background, namely, the Sendto function and the RecvFrom function are used, and the periodic detection message detection does not need to be continuously performed in the period, and only when any party transmits information, whether a link is detected temporarily or not is detected without obstacles; if the receiving party detects the link revocation when the receiving party wants to transmit the information to the transmitting party after the transmitting party and the receiving party construct the link, the receiving party needs to transmit the link information to the transmitting party, at this time, the roles of the transmitting party and the receiving party are reversed, the transmitting party is a background, and the receiving party is a foreground.
Step 6-4: the background communicates information to the foreground via the wireless link two.
The receiving party transmits the link message to the transmitting party, and after constructing the wireless link, the receiving party transmits the message to the transmitting party.
Thus, the information transmission speed and the applicability to wireless networks of both-side transmission modes of the foreground and the background can be improved.
The step 6-1 specifically comprises: the background receives the position and information mark of foreground transmitted, wherein the position of foreground includes: the domain name of the foreground and the thread identifier of the foreground;
the background stores the position and the information mark of the foreground on the background; and the background transmits the first determination message to the foreground, wherein the foreground constructs the first wireless link after receiving the first determination message. The information symbol is a predetermined dedicated marker.
After the transmitting party transmits the link message, the transmitting party is connected with the detection thread of the receiving party to execute the link construction, wherein the transmitting party is a foreground, and the receiving party is a background; the transmitting party firstly transmits the task detection position of the transmitting party, namely the domain name and the thread, and a special information mark to the receiving party, the receiving party stores the received task detection position in the main memory of the receiving party temporarily and feeds back the received task detection position to the transmitting party to determine the information, and the transmitting party starts to execute information transmission after receiving the determined information.
And the thread in the task detection position of the transmitter is the thread identifier of the task detection thread started by the transmitter.
The step 6-3 specifically comprises: the background is connected with the foreground which the domain name stored on the background belongs to again, and information marks are transmitted to the foreground; the background transfers the position of the background towards the foreground, wherein the position of the background comprises: the domain name of the background and the thread mark of the background, if the information mark received by the foreground is the same as the information mark transmitted to the background after the wireless link is constructed, the position of the background is stored in the foreground; and after receiving the determined message II transmitted by the foreground, the background constructs a wireless link II.
Wherein, after the transmitting party transmits the link message and constructs the link with the receiving party, the transmitting party detects the link revocation when the receiving party wants to transmit the message to the transmitting party during the period that the transmitting party transmits the message to the receiving party, at this time, the receiving party needs to transmit the link message to the transmitting party and constructs the link with the transmitting party; that is, the receiving party is linked with the construction thread via the transmitting party to which the domain name of the transmitting party temporarily stored locally is connected again, and transmits the same information token to the transmitting party for identification, if the information token transmitted by the transmitting party to the receiving party in the past is the same as the information token transmitted by the receiving party, the transmitting party and the receiving party construct the link; at this time, the receiving party transmits the task detection position of the receiving party, namely, the domain name and the thread, to the transmitting party, and after the transmitting party stores the task detection position of the receiving party, the receiving party transmits the confirmation message to the receiving party, and the receiving party constructs the link after receiving the confirmation message transmitted by the transmitting party.
At this time, the roles of the transmitting party and the receiving party are reversed, the transmitting party is the background, and the receiving party is the foreground.
During the period of receiving information transmitted by the foreground at the background, if the foreground detects that a wireless link is cancelled, the background receives a link message and an information mark transmitted by the foreground again; the background compares the received information marks with the stored information marks; and if the information marks received by the background are the same as the information marks stored by the background, the background and the foreground construct a wireless link one again.
During the period that the transmitting party transmits information to the receiving party, if the link revocation is detected when the transmitting party transmits the information to the receiving party in the period, the transmitting party is connected with the detection thread of the receiving party again to execute the link construction, and transmits the same information mark to the receiving party for identification, at the moment, the transmitting party is still the foreground, and the receiving party is still the background; if the receiving party recognizes that the information token it stores is the same as the information token transmitted from the transmitting party, a wireless link-once reconfiguration is performed.
The present invention eliminates the conventional periodic detection message detection scheme of both sides transmission, so that it is not necessary to maintain the link detection without any obstacle during all the information transmission periods, and it is only necessary to ensure the link is achieved at the current time of the information to be transmitted.
Just like the receiving party connected to the transmitting party in different places to execute the operation of transmitting the debugging report, the whole operation is continuous for 120 seconds, the receiving party needs to respond to the progress and the condition of the debugging report transmission at 20 th, 52 th and 120 th seconds, so that the debugging report transmission period only needs to ensure that the link is smooth when starting (the transmitting party transmits the debugging report to the receiving party), at 20 th, 52 th (the receiving party responds to the progress of the debugging report transmission to the transmitting party), and at 120 th (the receiving party responds to the last condition of the transmitting party), even if the link canceling user is not aware of the abnormal condition of the wireless network in other time periods, the user is not influenced, and the applicability of the wireless network is improved.
The mode provided by the invention abandons the existing system that two sides transmit detection messages periodically to detect and maintain the link without barriers, corrects the standard of where to require to detect and where to cancel the retransmission, reduces the information transmission for detection with great ineffectiveness under the configuration of large time, and greatly improves the information transmission speed.
In addition, the smart phone and the controller can be alternately used as a foreground of a transmitting party and a background of a receiving party, and no constraint that only the foreground automatically constructs a link towards the background is provided; the link can be automatically constructed and the information transmission can be executed again when the random party detects the link revocation during the information transmission, and particularly under the condition that the wireless network is unreliable and the link is frequently revoked, the punctuality of the information transmission can be ensured.
In the prior art, the two-side transmission mode only needs to run the task detection thread in the background to obtain the link message transmitted in the foreground, and both the transmitting party and the receiving party of the invention need to use the task detection thread to execute the task link detection.
The step 6 specifically further includes:
step A-1: after the foreground transmits a link message I to the background, the foreground and the background construct a wireless link I;
step A-2: the foreground transmits information to the background through a wireless link;
step A-3: during the period that the foreground transmits information to the background, if the foreground detects that the wireless link is cancelled, the foreground transmits the link message I and the information mark to the background again, wherein the information mark is the information mark transmitted to the background by the foreground after the wireless link is constructed.
The step A-1 specifically comprises the following steps: the foreground transmits the position and information sign of the foreground to the background, wherein, the position of the foreground includes: the domain name of the foreground and the thread identification of the foreground, and the position and the information mark of the foreground are stored and stored on the background by the background; and after receiving the determined message I transmitted by the background, the foreground constructs a wireless link I.
And during the period that the foreground transmits information to the background, if the background transmits information to the foreground and detects that the first wireless link is cancelled, the foreground receives a second link message transmitted by the background and constructs a second wireless link with the background.
The foreground receives a second link message transmitted by the background, and constructs a second wireless link with the background, and the method specifically comprises the following steps: the foreground receives the information mark transferred by the background and the position of the background, wherein, the position of the background comprises: a background domain name and a background thread identifier; if the information mark received by the foreground is the same as the information mark transmitted by the foreground to the background after constructing the wireless link I, the foreground stores the position of the background on the foreground and transmits a determined message II to the background, wherein the background constructs the wireless link II after receiving the determined message II.
