In addition, in practical application, the intelligent water meter specifically sends the real-time water consumption information of the user to the remote terminal in a mode that:
the intelligent water meter transmits the real-time water consumption information of a user to an intermediate server in a wireless network for temporary storage, then the intermediate server transmits the real-time water consumption information of the user to a remote terminal in sequence, so the intelligent water meter transmits the real-time water consumption information of the user to the intermediate server for temporary storage, then the intermediate server transmits the real-time water consumption information of the user to the remote terminal in sequence, the intelligent water meter is wirelessly connected with the intermediate server, the intermediate server is wirelessly connected with the remote terminal, the bandwidth of the wireless network is a key element of the performance that the remote terminal receives the real-time water consumption information of the user, when the bandwidth of the wireless network is not good, the real-time water consumption information of the user in the temporary storage space of the intermediate server is transmitted in sequence, and the remote terminal can not obtain the real-time water consumption information of the user smoothly in time, problems of poor or even obstructed accommodation occur.
The intelligent water meter specifically comprises the following steps that:
the intelligent water meter transmits real-time water consumption information of a user to an intermediate server for temporary storage, then the intermediate server transmits the real-time water consumption information of the user to a remote terminal in sequence, so that the intelligent water meter transmits the real-time water consumption information of the user to the intermediate server for temporary storage, then the intermediate server transmits the real-time water consumption information of the user to the remote terminal in sequence, the intelligent water meter is in wireless connection with the intermediate server, the intermediate server is in wireless connection with the remote terminal, and the intermediate server comprises an obtaining program, a deriving program and a determining program;
the method for receiving the real-time water consumption information of the user by the remote terminal under eyes is that the real-time water consumption information of the user stored in the intelligent water meter in the wireless network is transmitted to the remote terminal and received by the remote terminal, but the transmission is delayed when the bandwidth of the wireless network is not good, so that the remote terminal receives the real-time water consumption information of the user and stops or even blocks, and the user feels not good during the application.
The method comprises the steps that an information message of user real-time water consumption information to be transmitted to a remote terminal is received by a program through an intelligent water meter, the user real-time water consumption information is transmitted in an information message format, the first time when the previous information message is successfully transmitted and the second time when the current information message is to be transmitted are summed up, and the interval of the first time when the previous information message is successfully transmitted to the second time when the current information message is to be transmitted is the time consumed by the remote terminal for receiving the previous information message; the obtaining program then obtains the bandwidth of the wireless network when the remote terminal receives the current message;
the export program receives the information message to be transmitted to the remote terminal subsequently and obtains the bandwidth of the current wireless network obtained by the program, the length value of the received information message and the bandwidth of the current wireless network are combined with the export method to export the duration D required for transmitting the information message to be transmitted to the remote terminal subsequently, the interval two between the first time when the transmission of the previous information message is successfully achieved and the second time when the current information message is ready to be transmitted is synchronously exported, and the value of the exported duration D and the interval two is transmitted to the identification program.
The program is identified as follows: comparing the interval between the first time when the transmission of the previous information message is successfully achieved and the time interval to prepare for transmitting the next information message with the value of the duration D, and transmitting the obtained information message to the remote terminal when the determined value is that the interval is two and is higher than the duration D; and when the determined value is that the time interval two is higher than the duration D, the message is cancelled.
Here, before the information message of the real-time water consumption of the user is transmitted to the remote terminal through the intelligent water meter, the information message is firstly processed by the identification of the intermediate server, the information message is obtained by the program after being sent out by the intelligent water meter, and the sum of the time when the previous information message is successfully transmitted and the time when the current information message is ready to be transmitted is continuous, so that the time interval between the time when the previous information message is successfully transmitted and the time when the current information message is ready to be transmitted is the time required for the previous information message to be received by the remote terminal, the obtained program then obtains the bandwidth of the current wireless network by running the bandwidth test program through the export program, for example, the bandwidth of the current wireless network is obtained by running the ping instruction or the 360 program, the export program evaluates the time length D required for receiving the information message to be transmitted by the remote terminal when the information message appears by means of the length value of the received information message and the bandwidth of the current wireless network; comparing the interval two from the moment when the previous information message is successfully transmitted to the moment when the next information message is ready to be transmitted with the value of the duration D, when the preset value is that the interval two is higher than the duration D, the length of the previous information message is not much, if the previous information message is received by the remote terminal in the interval two, the current information message can be received by the remote terminal in the corresponding time period, and at the moment, the remote terminal receives the real-time water consumption information of the user smoothly and cannot form delay and retardation when the remote terminal receives the real-time water consumption information of the user; on the contrary, when the predetermined value is that the time interval two is not higher than the time length D, it indicates that under the condition that the length value of the previous message is not much, the time length required for receiving the current message is not short, the current message cannot be received in the corresponding time period, and the remote terminal continuously receives the next message, which is unfavorable, and often forms the delay of receiving the real-time water consumption information of the user, or even the hungry receiving block, at this time, the determining program cancels the message which is transmitted to the remote terminal at present, and then the subsequent next message is obtained through the obtaining program.
The intermediate server also comprises a temporary storage program, the temporary storage program stores information messages of the real-time water consumption of all the users, which need to receive the real-time water consumption information of the users, into the temporary storage program, and then the real-time water consumption information of the users is transmitted to the remote terminal by using the format of the information messages.
Under general conditions, under the condition of the current wireless network, the bandwidth of the wireless network is in a fluctuating state with small amplitude in different continuous time intervals, and can be used as a fluctuating state with small amplitude oscillation, so that the value of the derived time interval two is also in a fluctuating state with small amplitude in the continuous time intervals, thus comparing the time interval two from the moment when the transmission of the previous information message is successfully achieved to the moment when the transmission of the next information message is prepared to be transmitted and the value of the duration D, and transmitting the obtained information message to the remote terminal when the determined value is that the time interval two is higher than the duration D; when the determined value is that the time interval two is higher than the duration D, the information message is cancelled; after the current information message is cancelled, the program receives the next information message in real time, in addition, the remaining time interval after the current information message is received is delayed to the next information message, namely, the time interval two corresponding to the derivation of the next information message is changed into S plus the time interval two originally derived, S is the received time length evaluated aiming at the previous information message of the next information message, and the next information message can be received when the sum of S plus the time interval two originally derived is higher than the time length D facing to the next information message. And if the latter message is not received, the receiving time interval II of the latter message is continuously increased until the time length D is longer than the evaluation derived time length, so that the message is received.
The derivation procedure is used to derive real-time wireless network delivery speed.
Therefore, the intermediate server for transmitting the information message of the real-time water consumption of the user obtains the information message of the real-time water consumption information of the user, sums up the time points of the transmission of the previous information message and the transmission preparation of the current information message, obtains the bandwidth of the current wireless network, derives the time length required for transmitting the current information message, compares the time length with the difference value of the time points of the transmission of the current information message and the transmission preparation of the current information message, transmits the information message to the remote terminal when the time length is less than the difference value, or cancels the information message, thereby removing the adverse effect of the data transmission of the real-time water consumption information of the user under the condition of poor bandwidth of the wireless network, ensuring that the remote terminal receives the real-time water consumption information of the user with high efficiency, and improving and ensuring that the experience of the user during the operation.
The intelligent water meter is right the mode that remote terminal sends the real-time water consumption information of user, and the process of this mode includes:
step 1: the method comprises the steps that an information message of user real-time water consumption information to be transmitted to a remote terminal is received by a program through an intelligent water meter, the user real-time water consumption information is transmitted in an information message format, the first time when the previous information message is successfully transmitted and the second time when the current information message is to be transmitted are summed up, and a time interval two between the first time when the previous information message is successfully transmitted and the second time when the current information message is to be transmitted is derived;
the method comprises the steps that an information message of user real-time water consumption information to be transmitted to a remote terminal is received by a program through an intelligent water meter, the user real-time water consumption information is transmitted in an information message format, the transmitted information message format totals the first moment when the previous information message is successfully transmitted and the second moment when the current information message is ready to be transmitted, and the interval of the first moment when the previous information message is successfully transmitted to the second moment when the current information message is ready to be transmitted is the time consumed by the remote terminal for receiving the previous information message;
step 2: acquiring the bandwidth of a wireless network when the remote terminal receives the current information message;
then obtaining the bandwidth of a wireless network when the remote terminal receives the current information message, wherein the information message of the real-time water consumption of the user is firstly processed by the identification of the intermediate server before being transmitted to the remote terminal through the intelligent water meter, the information message is obtained by a program after being sent out by the intelligent water meter, and the sum of the time I when the previous information message is successfully transmitted and the time II when the current information message is ready to be transmitted is ensured, the smooth performance of the remote terminal for receiving the real-time water consumption information of the user is ensured, and each information message is continuously transmitted to the remote terminal, so the time interval between the time I when the previous information message is successfully transmitted and the time II when the current information message is ready to be transmitted is the time required for the previous information message to be received by the remote terminal;
and step 3: deriving a time length D required for transmitting the subsequent information message to be transmitted to the remote terminal by virtue of the length value of the received information message and the current bandwidth of the wireless network;
by means of the length value of the received information message and the bandwidth of the current wireless network, a time length D required for transmitting the subsequent information message to be transmitted to the remote terminal is derived by combining a derivation method, and a time interval II between the first time when the transmission of the previous information message is successfully achieved and the second time when the current information message is ready to be transmitted is synchronously derived;
and 4, step 4: comparing the interval between the first time when the transmission of the previous information message is successfully achieved and the time interval to prepare for transmitting the next information message with the value of the duration D, and transmitting the obtained information message to the remote terminal when the determined value is that the interval is two and is higher than the duration D; and when the determined value is that the time interval two is higher than the duration D, the message is cancelled.
Here, before the information message of the real-time water consumption of the user is transmitted to the remote terminal through the intelligent water meter, the information message is firstly processed by the identification of the intermediate server, the information message is obtained by the program after being sent out by the intelligent water meter, and the sum of the time when the previous information message is successfully transmitted and the time when the current information message is ready to be transmitted is continuous, so that the time interval between the time when the previous information message is successfully transmitted and the time when the current information message is ready to be transmitted is the time required for the previous information message to be received by the remote terminal, the obtained program then obtains the bandwidth of the current wireless network by running the bandwidth test program through the export program, for example, the bandwidth of the current wireless network is obtained by running the ping instruction or the 360 program, the export program evaluates the time length D required for receiving the information message to be transmitted by the remote terminal when the information message appears by means of the length value of the received information message and the bandwidth of the current wireless network; comparing the interval two from the moment when the previous information message is successfully transmitted to the moment when the next information message is ready to be transmitted with the value of the duration D, when the preset value is that the interval two is higher than the duration D, the length of the previous information message is not much, if the previous information message is received by the remote terminal in the interval two, the current information message can be received by the remote terminal in the corresponding time period, and at the moment, the remote terminal receives the real-time water consumption information of the user smoothly and cannot form delay and retardation when the remote terminal receives the real-time water consumption information of the user; on the contrary, when the predetermined value is that the time interval two is not higher than the time length D, it indicates that under the condition that the length value of the previous message is not much, the time length required for receiving the current message is not short, the current message cannot be received in the corresponding time period, and the remote terminal continuously receives the next message, which is unfavorable, and often forms the delay of receiving the real-time water consumption information of the user, or even the hungry receiving block, at this time, the determining program cancels the message which is transmitted to the remote terminal at present, and then the subsequent next message is obtained through the obtaining program.
Under general conditions, under the condition of the current wireless network, the bandwidth of the wireless network is in a fluctuating state with small amplitude in different continuous time intervals, and can be used as a fluctuating state with small amplitude oscillation, so that the value of the derived time interval two is also in a fluctuating state with small amplitude in the continuous time intervals, thus comparing the time interval two from the moment when the transmission of the previous information message is successfully achieved to the moment when the transmission of the next information message is prepared to be transmitted and the value of the duration D, and transmitting the obtained information message to the remote terminal when the determined value is that the time interval two is higher than the duration D; when the determined value is that the time interval two is higher than the duration D, the information message is cancelled; after the current information message is cancelled, the program receives the next information message in real time, in addition, the remaining time interval after the current information message is received is delayed to the next information message, namely, the time interval two corresponding to the derivation of the next information message is changed into S plus the time interval two originally derived, S is the received time length evaluated aiming at the previous information message of the next information message, and the next information message can be received when the sum of S plus the time interval two originally derived is higher than the time length D facing to the next information message. And if the latter message is not received, the receiving time interval II of the latter message is continuously increased until the time length D is longer than the evaluation derived time length, so that the message is received.
The derivation procedure is used to derive real-time wireless network delivery speed.
Therefore, the intermediate server for transmitting the information message of the real-time water consumption of the user obtains the information message of the real-time water consumption information of the user, sums up the time points of the transmission of the previous information message and the transmission preparation of the current information message, obtains the bandwidth of the current wireless network, derives the time length required for transmitting the current information message, compares the time length with the difference value of the time points of the transmission of the current information message and the transmission preparation of the current information message, transmits the information message to the remote terminal when the time length is less than the difference value, or cancels the information message, thereby removing the adverse effect of the data transmission of the real-time water consumption information of the user under the condition of poor bandwidth of the wireless network, ensuring that the remote terminal receives the real-time water consumption information of the user with high efficiency, and improving and ensuring that the experience of the user during the operation.
The utility model discloses an intermediate server that the information message transmission of the real-time water consumption of user used obtains the information message of the real-time water consumption information of user, total up the time point that the transmission was reached to the previous information message and the transmission is prepared to the current information message, and the bandwidth of obtaining current wireless network of discovery, derive the transmission current information message long enough, and reach the transmission with the previous information message of totaling and prepare the difference contrast of the time point of transmission with the current information message, transmit remote terminal when being less than this difference, this information message is just cancelled, from this, just can remove the adverse effect of the real-time water consumption information data transmission of user under the not good condition of wireless network bandwidth, it is high-efficient to let remote terminal receive the real-time water consumption information of user, improve and let the user experience during the application better.
The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
