When the business department terminal and the cloud server build a wireless link again, the business department terminal transmits the sub-information for storage, which is marked as non-transmitted sub-information for storage, to the cloud server; compared with the prior art, when the business department terminal and the cloud server build the wireless link again, the sub-information for storage does not need to be transmitted again, and the signal transmission speed can be improved.

The connecting bar R3 for fixedly connecting the supporting part R4 is plugged by a locking part, after the connecting bar R3 is damaged, the lower connecting bar R3 can be disassembled through the locking part, and the other connecting bar R3 is assembled, so that the repair is facilitated.

the business department terminal reduces the signals of valve control and coordinate positioning which need to be transmitted to the cloud server for storage, namely the initial signals, and obtains sub-information for storage, namely the capacity of the reduced signals is lower than the signals of valve control and coordinate positioning which need to be transmitted to the cloud server for storage, namely the capacity of the initial signals; running this step can reduce the storage capacity; under the condition that the signal capacity of valve control and coordinate positioning which need to be transmitted to the cloud server for storage is not small, the signal capacity of valve control and coordinate positioning which need to be transmitted to the cloud server for storage can be reduced into a plurality of pieces of sub information for storage, for example, the signal capacity of valve control and coordinate positioning which need to be transmitted to the cloud server for storage is sixteen megabits and can be reduced into six thousand 100-byte sub information for storage, and the sub information for storage is reduced by a lot compared with the signal capacity of valve control and coordinate positioning which need to be transmitted to the cloud server for storage, so that the speed of transmitting the sub information for storage is increased by a lot compared with the speed of transmitting the signal capacity of valve control and coordinate positioning which need to be transmitted to the cloud server for storage.

the method for the business department terminal to establish the wireless link between the business department terminal and the cloud server comprises the following steps: can construct the wireless link between business department terminal and cloud server through business department terminal or cloud server, include specifically: before the wireless link is established, the business department terminal needs to be identified by the cloud server, or the cloud server needs to be identified by the business department terminal, so as to improve the reliability of the wireless link. For example, the cloud server stores the identification information in advance, the identification information is a character string 'wwwkkktttt', the identification information needs to be input into the business department terminal, then the identification information is sent to the cloud server to be compared, and after the input identification information is confirmed to be consistent with the identification information stored in the cloud server in advance, the wireless link can be established;

The business department terminal can transmit various sub information for storage under different link conditions, for example, when the wireless link is smooth, the business department terminal transmits the sub information for storage in the order from large to small according to the weight value of the signal corresponding to the sub information for storage, when the wireless link is blocked, the business department terminal transmits the sub information for storage from small to large according to the capacity of the sub information for storage, so that the purpose of flexibly transmitting a plurality of sub information for storage under different link conditions is achieved, the signal transmission speed is improved, and the time length of transmitting the sub information to the cloud server is reduced.

The hard disk of the business department terminal stores a set weight threshold, and the weight threshold is a set value which is used for comparing with the weight value of the signal of valve control and coordinate positioning; the plurality of pieces of sub information for storage may include sub information for storage in which a weight value of a corresponding signal is higher than a weight threshold and sub information for storage in which a weight value of a corresponding signal is lower than a weight threshold, and the method by which the business office terminal can deliver various pieces of sub information for storage under link conditions with different conditions may also include:

When a wireless link between a business department terminal and a cloud server is blocked, the stored sub-information is not rapidly transferred, the stored sub-information is often unsuccessfully transferred and then continuously transferred for a plurality of times, and for the stored sub-information of which the weight value of a corresponding signal is higher than a weight threshold value, if the stored sub-information is continuously transferred for a plurality of times, the probability of leakage of the stored sub-information is increased, and the reliability of the transfer of the stored sub-information cannot be ensured; therefore, the sub-information which is less important and has a low weight value and is used for storage is transmitted first, and the contribution of leakage of the sub-information transmission which has a weight value higher than the weight threshold value of the corresponding signal is reduced; when the wireless link between the business department terminal and the cloud server is smooth, the business department terminal transmits the sub-information for storage, of which the weight value of the corresponding signal is higher than the weight threshold value, to the cloud server in the order of the weight values from high to low, and then transmits the sub-information for storage, of which the weight value of the corresponding signal is lower than the weight threshold value, to the cloud server in the order of the weight values from high to low, so that the link resources can be fully utilized, the information transmission speed is increased, and the reliability of the sub-information for storage can be improved.

The step 5 can further include:

here, the business department terminal can start several processes, and when the wireless link is smooth, several pieces of sub information for storage can be concurrently transmitted to the several processes. For example, if the business office terminal starts K processes, the business office terminal can concurrently transfer K pieces of sub information for storage, where K is a natural number. Therefore, a plurality of sub information for storage can be transmitted simultaneously, and compared with the one-by-one transmitted information, the signal transmission speed can be increased.

After step 5, the following method can be performed:

here, the sub information for storage that is unsuccessfully transferred may be that the business office terminal unexpectedly cancels the wireless link when transferring the sub information for storage, so that the transfer of the sub information for storage is unsuccessful. Generally, after the business department terminal transmits a sub-message for storage to the cloud server, the cloud server responds to a response message if receiving the sub-message for storage, the business department terminal identifies the sub-message for storage as successful transmission after obtaining the response message, and if not, identifies the sub-message for storage as not transmitted.

When the wireless link between the business department terminal and the cloud server is cancelled, the business department terminal stores the sub-information for storage which is not transmitted yet and the sub-information for storage which is not transmitted yet in the plurality of sub-information for storage, and marks the sub-information for storage which is not transmitted yet and the sub-information for storage which is not transmitted yet into the sub-information for storage which is not transmitted;

when the business department terminal and the cloud server build a wireless link again, the business department terminal transmits the sub-information for storage, which is marked as non-transmitted sub-information for storage, to the cloud server; compared with the prior art, when the business department terminal and the cloud server build the wireless link again, the sub-information for storage does not need to be transmitted again, and the signal transmission speed can be improved.

the business department terminal executes the reduction of signals of valve control and coordinate positioning which need to be transmitted to the cloud server for storage by using a hybrid coding method formed by the combination of entropy coding and information source coding; specifically, a source coding method is firstly used for reducing signals which need to be transmitted to a cloud server for storage and are used for valve control and coordinate positioning to obtain a first code, then an entropy coding method is used for reducing the first code again to obtain a second code, and all the second codes are a plurality of pieces of sub information for storage. The entropy encoding method is run length coding, LZW coding, shannon coding, huffman coding, or arithmetic coding. The method comprises the steps of firstly utilizing a source coding method to reduce signals of valve control and coordinate positioning which need to be transmitted to a cloud server for storage to obtain a first code, then utilizing an entropy coding method to reduce the codes again to obtain a second code, wherein all the second codes are a plurality of sub-information used for storage, the reliability of the sub-information used for storage during transmission can be improved, and the reliability of the sub-information used for storage transmission can be improved through two times of coding for the signals of valve control and coordinate positioning which need to be transmitted to the cloud server for storage and are not expected to be disclosed or published.

Before proceeding to step 5, the following steps can also be performed:

The business department terminal uses the mixed coding method to reduce the signals of valve control and coordinate positioning which need to be transmitted to the cloud server for storage, and after the sub-information for storage is obtained, the business department terminal needs to transmit the information of the mixed decoding method corresponding to the mixed coding method to the cloud server in parallel, so that the cloud server uses the information of the mixed decoding method to decode the obtained sub-information for storage, and then stores the decoded signals on the cloud server.

The present invention has been described in an illustrative manner by the embodiments, and it should be understood by those skilled in the art that the present disclosure is not limited to the embodiments described above, but is capable of various changes, modifications and substitutions without departing from the scope of the present invention.
