The predetermined time can be 2-5 seconds;
and 7: when the timing value of the timing module is the same as the preset time, the controller II operates the termination module to stop the operation of the water pump, and then sends a reduction instruction sequence to be transmitted to the controller I through the wireless communication module III, the wireless network and the wireless communication module I;
and 8: after the controller receives the reduction instruction, the controller operates the reduction module to enable the
The second controller transmits the information message to the monitoring platform sequentially through the third wireless communication module, the wireless network and the second wireless communication module, that is, the second controller transmits the information message to the monitoring platform, and actually, the general situation is as follows: the number of the second controller is one, the number of the monitoring platforms is a plurality of progress with information transmission mode, so the transmission of the executed information message is from one end to multiple ends, that is, the transmission of the information message is executed through the group sending mode to ensure the transmission performance, however, under the condition of wireless network transmission, the group sending task is achieved through the public link of the information message transmission, because the group sending task achieved through the public link of the information message transmission does not use the feedback mode of positive feedback and negative feedback, the smooth achievement of the group sending information message transmission in the terminal can not be ensured, the current handling mode is to respond to the positive feedback and the negative feedback by the mode of active request retransmission to enable a certain monitoring platform in the feedback of the group sending information message to respond to the negative feedback if the successfully transmitted group sending information message is not received, the active request is activated to be transmitted again, even though the security of the group message transmission is ensured, the processing method is accompanied with the defect of reducing the transmission speed of the whole group message, like if a certain monitoring platform is continuously in a bad state in a certain time period, the monitoring platform continuously responds to negative feedback, and thus the transmission speed of the whole group message is aggravated to be reduced.
In the wireless network system, for the transmission of the mass-sending information messages, if the mass-sending information messages are successfully transmitted by the monitoring platform, the positive feedback is responded by the mode of actively requesting to transmit again, if the mass-sending information messages are not successfully transmitted, the negative feedback is uploaded in time by the mode of actively requesting to transmit again, and the second controller can activate the active request to transmit again after obtaining the negative feedback.
If the mass-sending information message which is transmitted again is not received, the monitoring platform which uploads the negative feedback continuously uploads the negative feedback, so that for the mass-sending information message transmission executed by the controller II, even if the introduction of the mode of actively requesting the retransmission ensures the safety, the continuous negative feedback uploading forms no small pressure on the transmission.
Therefore, the transfer operation mode of the mass-sending information message is changed, so that the safe transfer of the mass-sending information message between two pairs of a plurality of monitoring platforms by one controller is realized, and the adverse effect on the transfer is avoided.
The second controller transmits the information message to the monitoring platform sequentially through a third wireless communication module, a wireless network and a second wireless communication module, namely the second controller transmits the information message to the monitoring platform, the number of the second controller is one, and the number of the monitoring platforms is multiple;
the second mode of the controller transmitting the information message to the monitoring platform comprises the following steps:
s-1: receiving a control message uploaded by a monitoring platform during the transmission of the group-sending information message, wherein the control message contains information which is responded by the monitoring platform and is not successfully transmitted to the group-sending information message;
the transmission system comprises a second controller and a monitoring platform, wherein the second controller transmits the mass-sending information messages to the monitoring platforms in the mass-sending task, if the monitoring platforms do not successfully obtain the mass-sending information messages transmitted by the second controller during the transmission of the mass-sending information messages, control message uploading is executed, and the second controller correspondingly receives the control messages uploaded by the monitoring platforms to obtain that the mass-sending information messages executed by the monitoring platforms do not successfully respond;
s-2: activating an improved retransmission mode by means of the control message uploaded by the monitoring platform and a preset state;
acquiring a preset state, and activating an improved re-transmission mode when the state supports improved re-transmission in a transmission system under the view and has re-transmission performance;
here, the improved re-transmission mode is re-transmission of the mass message performed when the preset state is met, the number of times of re-transmission can be equipped, and binary codes of re-transmission redundant marking sequence are 0000, 0010, 0011 and 0001, which are consistent with the mass message transmission, the format of the re-transmitted message is the same as that of the public link for mass message transmission, and the re-transmission time point and the re-transmitted frequency band can be flexibly adjusted on the configuration of the public link;
s-3: the mass-sending message is required to be transmitted again through an improved retransmission mode;
activating an improved re-transmission mode in the controller II to request to execute re-transmission of the mass-sending information message, so as to re-transmit the mass-sending information message to the monitoring platform involved in the mass-sending, and at the moment, the monitoring platform which does not successfully obtain the mass-sending information message obtains the mass-sending information message through the mode;
by adopting the mode, an improved re-transmission mode is introduced into the transmission system to monitor the unsmooth execution response of the group-sending information messages in the system, the problem that the group-sending cannot ensure the transmission safety because the positive feedback and the negative feedback response are not transmitted is solved, in addition, the transmission performance is improved, and the monitoring platform with poor state in the transmission system can be obviously improved.
The method for activating the improved retransmission mode by means of the control message uploaded by the monitoring platform and the preset state comprises the following steps:
s-2-1: obtaining the bandwidth of the residual transmission system;
estimating the bandwidth of the target residual transmission system and obtaining the bandwidth of the residual transmission system so as to obtain the current information transmission performance by the obtained bandwidth of the residual transmission system;
s-2-2: judging whether the software and hardware performance of the second controller and the monitoring platform of the preset transmission system and the bandwidth of the residual transmission system are in accordance with the preset state, if so, executing the process in S-2-3, and if not, performing treatment;
obtaining the preset software and hardware performances of the second controller and the monitoring platform, wherein the preset hardware performances of the second controller and the monitoring platform are used for obtaining the retransmission which is not the support improvement at present, namely the software and hardware performances of the second controller and the monitoring platform are not the configuration which can support the improvement, and if the configuration which can support the improvement is set, the retransmission which is the support improvement at present is represented;
judging whether the bandwidth of the residual transmission system obtained by evaluation exceeds a bandwidth threshold value in a preset state, if so, indicating that the transmission system has retransmission performance at the moment, and executing retransmission of the mass-sending information message;
s-2-3: an improved re-delivery mode is activated.
The method for requiring to transmit the mass-sending message again through the improved retransmission method comprises the following steps:
s-3-1: redundant marks are formed by means of the mass-sending information messages which are transmitted again;
the redundant mark is an information message group which needs to be transmitted again, and the redundant mark comprises a mass-sending information message which is not transmitted to the monitoring platform smoothly;
s-3-2: transmitting the redundant flag according to the re-transmission manipulation information set in advance;
the preset re-transmission operation information corresponds to an improved re-transmission mode and comprises information such as re-transmission times, a re-transmission sequence of redundant marks and an information message format;
the corresponding time point and frequency domain can be flexibly adjusted in the transmission of the redundant marks, namely, the retransmission time point can be a sub-message transmitted later, and the frequency range of retransmission can be flexibly scheduled, namely, the same frequency range as that of continuous application or different frequency ranges are respectively applied;
corresponding to the improved retransmission mode, the state reversal mode is provided for the transmission system, when the preset state is not met any more or the link performance becomes better, the transmission system, that is, the controller II discards the improved retransmission mode, does not execute the improved retransmission mode any more, and restores the group sending mode.
Just as in the mass-sending, after the improved re-delivery is activated, the application sub-message +0000 is delivered initially, the redundant marking number is 0000, and it is possible to deliver the redundant markings 0010, 0011 and 0001 in the first, fifth and sixth sub-messages.
After the second controller requests to transmit the mass-sending message again through the improved retransmission method, the method for transmitting the message to the monitoring platform by the second controller further includes:
b-1: detecting whether the retransmission of the group sending information message is not in accordance with the preset state any more, if so, switching to B-2 for execution, and if not, continuously executing retransmission in S-3;
if the current state is not in accordance with the preset state any more, like the bandwidth of the current residual transmission system is not abundant, the current state is not in accordance with the preset state of the improved retransmission, so the improved retransmission can not be carried out any more;
b-2: activating and terminating the retransmission of the mass-sending message;
after the second controller requests to transmit the mass-sending message again through the improved retransmission method, the method for transmitting the message to the monitoring platform by the second controller further includes:
c-1: estimating the link performance;
c-2: judging whether the performance of the link is better, if so, switching to C-3 to execute, and if not, continuously executing retransmission in S-3;
during the retransmission of the mass-sending message, the link performance is detected to restore the mass-sending process when the link performance becomes better;
c-3: activating and stopping the retransmission of the mass-sending information message, and restoring mass sending;
thus, the method for transmitting and controlling the group sending information message correspondingly comprises the following steps:
d-1: detecting whether the group sending information message transmitted by the controller II is successfully sent;
the monitoring platform, namely in the process of receiving the group sending information message transmitted by the controller II, detects whether the group sending information message is successfully sent, so as to obtain the occurrence condition that the group sending information message does not successfully arrive;
d-2: when detecting that the mass-sending message does not arrive smoothly, activating and forming a corresponding control message, wherein the control message has information that the mass-sending message is not transferred smoothly;
if the monitoring platform does not successfully receive the group sending message transmitted by the second controller, the corresponding control message is activated and formed, and the information which is not successfully sent by the group sending message is responded to the second controller through the control message;
d-3: the control message is passed towards controller two.
The method for transferring and operating the mass-sending message further comprises the following steps: and receiving the mass-sending information message which is retransmitted by the second controller in the improved retransmission mode, wherein the mass-sending information message is the mass-sending information message which does not arrive successfully in the mass-sending information message transmitted by the second controller.
Thus, the monitoring platform is an arbitrary monitoring platform involved during the mass sending of the second controller. That is, any monitoring platform can not successfully transmit the mass-sending message back to the controller two, that is, the mass-sending message can be received again by transmitting the control message and executing the response through the control message, and the mass-sending message can be recovered during the mass-sending period when the mass-sending message is returned in the activated state, so that the transmission safety is ensured, the mass-sending message can be adaptively improved and transmitted and returned again, and the mass-sending message can be applied to various information transmission states and has good application characteristics.
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.
