In order to monitor the cutting platform based on earthquake relief work, a camera is arranged beside the cutting platform based on earthquake relief work and is connected with a controller, and the controller is also connected with a GSM communication unit, so that short message reminding of images of the cutting platform based on earthquake relief work, acquired by the camera, is sent to a monitoring platform such as a smart phone configured for monitoring personnel in a message mode through the GSM communication unit, and high-speed rail overhaul personnel can know the images of the cutting platform based on earthquake relief work, acquired by the camera; the monitoring platform can also transmit the message of the short message of the image of the cutting platform based on earthquake relief and emergency rescue operation collected by the camera to the controller and transmit the message to the liquid crystal screen connected with the controller for display, the current message transmission mode calculates the message to divide the message into the number of sub-messages and the capacity of each sub-message, when the message transmitted by the monitoring platform to the monitoring platform is transmitted, the controller firstly informs the monitoring platform of transmitting the message such as the capacity of the message, then each sub-message transmits an instruction required by the controller, a mode responded by the monitoring platform is transmitted gradually until the transmission is finished, when the message transmitted by the monitoring platform to the controller is transmitted by the monitoring platform, the message such as the capacity of the message required to be transmitted to the controller is transmitted by the controller, and then the message mode is returned by the monitoring platform, successively transmitting the sub-messages of the messages transmitted to the monitoring platform until the monitoring platform transmits the messages transmitted to the monitoring platform to the controller; such modes are not complicated to achieve, but are accompanied by drawbacks like: because the controller waits for the response of the message to be transmitted after the controller transmits the message, and then transmits the latter message, the transmission delay is formed, and the message transmission rate is not high.
The controller encapsulates the received image information of the cutting platform based on earthquake relief work into messages and transmits the messages to the monitoring platform for backup; the monitoring platform can also transmit and display the message transmitted to the monitoring platform, so that the message transmitted between the controller and the monitoring platform is formed.
The message is transmitted between the controller and the monitoring platform, and the method comprises the following steps:
S-A1: the controller transmits a message to be transmitted to the monitoring platform towards the monitoring platform, and the message to be transmitted to the monitoring platform has the capacity of the message to be transmitted to the monitoring platform, so that the monitoring platform can determine whether the message is transmitted or not according to the capacity of the message to be transmitted to the monitoring platform;
preferably, the message to be transmitted to the monitoring platform further includes a mark code set for the message, so that the monitoring platform stores the received message, and registers the storage pointer of the message and the mark code of the message in the information table.
S-A2: the controller determines the number of the first sub-messages transmitted in batches for the first time and the capacity of the first sub-messages;
S-A3: the controller decomposes the message to be transmitted by the monitoring platform and transmits the sub-messages with the number of the sub-messages to the monitoring platform according to the capacity of the sub-message I;
and after confirming that the current link with the GSM network is unblocked, the controller determines the number of the second sub-messages transmitted in batches again and the capacity of the second sub-messages, and transmits the second sub-messages with the number of the second sub-messages to the monitoring platform according to the capacity of the second sub-messages until the message transmission corresponding to the message transmission capacity of the monitoring platform is finished.
After receiving the message transmitted to the monitoring platform, the monitoring platform disconnects the link of message transmission if the message transmission is determined to be finished according to the message transmission capacity of the monitoring platform.
The batch transmission is that a plurality of sub-messages are transmitted in sequence, and the transmission of each sub-message is not required to be transmitted after the response of the monitoring platform.
Here, the number of the first sub-messages in the S-a2 and the capacity of the first sub-messages in the message transferred between the controller and the monitoring platform, and the number of the second sub-messages in the S-A3 and the capacity of the second sub-messages can be the same or different; when the number of the sub-messages transmitted in double times is the same as the capacity of the sub-messages, the transmission operation is executed according to the same number of the sub-messages and the same size of the sub-messages; during each transfer, the controller must set the number of sub-packets and the capacity of the sub-packets to be transferred in batches according to the capacity of the temporary storage space of its internal processor and the state of the GSM network, and when the capacity of the temporary storage space of the processor of the controller is different from the GSM network state during the double transfer, the number of sub-packets to be transferred in double and the capacity of the sub-packets determined by the controller will be different.
The S-A3 comprises the following steps after confirming that the link of the GSM network is unblocked:
the controller transmits a check instruction of a link to the GSM network to a monitoring platform; and when receiving the GSM network smooth response returned by the monitoring platform according to the link verification instruction of the GSM network, confirming that the first batch transmission is smooth.
Specifically, when a message is transmitted to the monitoring platform, the controller transmits sub-messages to the monitoring platform in batches, and the controller needs to check whether the message transmitted in batches for the first time is transmitted successfully or not in order to avoid the excessive pressure of the temporary storage space of the controller under multiple communications and confirm whether the monitoring platform obtains the previously transmitted sub-message or not. Because the invention is directed at message transmission under the handshake protocol, the monitoring platform can be verified to have the message transmitted previously by the controller only by checking whether the GSM network is unobstructed or not; the detailed verification method comprises the following steps: the controller transmits a link checking instruction for checking whether the link of the GSM network is unblocked to the monitoring platform, the monitoring platform executes judgment after obtaining the instruction, and a response of the unblocked GSM network is transmitted back to the controller when the GSM network is unblocked. When the controller obtains the clear response of the GSM network, it confirms that the first batch transmission is smooth.
After confirming that the link of the GSM network is unblocked in the S-A3, the controller then determines the number of the second sub-messages and the capacity of the second sub-messages which are transmitted in batches again, and transmits the second sub-messages with the number of the second sub-messages to the monitoring platform according to the capacity of the second sub-messages until the message transmission corresponding to the message transmission capacity of the monitoring platform is finished; after the controller transmits the message corresponding to the message transmission capacity of the monitoring platform, the controller transmits a link request for checking the GSM network to the monitoring platform, waits for the monitoring platform to transmit a smooth response of the GSM network back, and after the response is obtained, the controller finishes the transmission operation, and the controller and the monitoring platform disconnect the link respectively and finish the transmission.
When the controller transmits the message to the monitoring platform, the controller does not need to execute one confirmation after all sub-messages are transmitted in batches, and the monitoring platform responds after the controller executes one confirmation after all sub-messages determined by the controller are transmitted in batches; thereby reducing the occurrence of hysteresis and improving the transfer rate.
Here, the message to be transmitted to the monitoring platform by the controller in S-a1 also has account information of the message returnable controller, so that the monitoring platform uses the account information of the message returnable controller to check whether the account requesting to transmit the message to the monitoring platform by the monitoring platform has the return function;
the message to be transmitted to the monitoring platform also has a prompt message indicating whether the message can be removed or not, so that the monitoring platform can remove or not remove the received message transmitted to the monitoring platform by using the prompt message indicating whether the message can be removed or not.
In the invention, in the message that the message transmitted to the monitoring platform by the controller in the S-A1 is transmitted to the monitoring platform, the message can be returned to the controller, and here, the message can be returned to the controller to confirm the registration function; the effect of this kind of information is to make the monitoring platform use the function that the message can pass back the account information check instruction of the controller to transmit the message transmitted to the monitoring platform to the user of the controller, so the key to process is to ensure that the monitoring platform transmits the message transmitted to the controller without leakage.
In detail, the controller submits the message in the message to be transmitted to the monitoring platform to transmit the message back to the account information of the controller; the message can be returned to the account information of the controller to be refreshed, and the refreshing is that a user of the account gives the message in a message which is to be transmitted to the monitoring platform for a plurality of times and can return the account information of the controller; the monitoring platform needs to merge the registered account information and the account information given newly each time, and account information which does not exist in the registered account information is added into the account information which can be returned to the controller by the message stored in the monitoring platform.
Preferably, the message to be transmitted to the monitoring platform by the controller further includes a prompt message indicating whether the message can be removed, and the message to be transmitted by the controller is set by the controller and registered in the message to be transmitted to the monitoring platform, so that the monitoring platform can give different control modes according to whether the message can be removed when the message is controlled by the monitoring platform, and the message is controlled by the monitoring platform; here, the monitoring platform does not perform the operation when the prompt message indicates that the message cannot be removed.
In view of the current defects that if the controller is interrupted during the transmission, such as an unexpected link disconnection, the controller needs to transmit the message to the monitoring platform again, the message cannot be transmitted from the interrupted position again, and the time and labor consumption of the retransmission from the beginning often occur, the invention also provides a method for transmitting the message from the interrupted position again, before the message transmission corresponding to the message transmission capacity of the monitoring platform is finished, the method for transmitting the message between the controller and the monitoring platform further comprises the following steps:
if the transfer operation is stopped, when the controller initiates the transfer operation of the message with the stopped transfer again, the controller transfers a command for transferring again to the monitoring platform, wherein the command for transferring again comprises the mark code of the message;
the controller receives the response of the command transmitted by the monitoring platform for retransmission, and transmits the messages to the monitoring platform in batches from the transmission stopping position corresponding to the byte number according to the byte number of the sub-messages transmitted to the monitoring platform in the command response for retransmission until the message transmission corresponding to the message transmission capacity of the monitoring platform is finished.
Because the controller is often in an unexpected state during the transfer, such as an unexpected link disconnection, the controller can overcome the time-consuming and labor-consuming disadvantage of re-transferring from the beginning if it can then continue to transfer the message that has not been transferred to the end. Here, the controller stops the transmission of the message under the condition that the message capacity corresponding to the transmitted sub-message is lower than the message capacity transmitted to the monitoring platform, that is, the controller is in an unexpected state and is stopped; the monitoring platform registers the number of bytes of the sub-message which is transmitted to the monitoring platform and corresponds to the transmission stopping position; the transfer stop position is the stop position for transferring the message to the monitoring platform.
When the unexpected state is released and the controller executes the transfer operation of the message of which the transfer is stopped again, the controller then transfers a command of transferring again to the monitoring platform, wherein the command of transferring again comprises the mark code of the message; the mark code of the message is beneficial to the monitoring platform to detect the message which is stopped for the first time, after the monitoring platform obtains the command which is transmitted again, a transmission link is constructed, the byte number of the sub-message which is transmitted to the monitoring platform is registered in the response of the command which is transmitted again and returned to the controller, and the controller transmits the message to the monitoring platform in batches from the transmission stopping position corresponding to the byte number until the message transmission corresponding to the message transmission capacity of the monitoring platform is finished; in this way, the controller achieves the function of re-transmission from the position of suspension.
When the controller transmits a message to the monitoring platform, the detailed steps comprise:
S-B1: the monitoring platform transmits a message to be transmitted to the monitoring platform, wherein the message to be transmitted to the monitoring platform comprises the message capacity to be transmitted to the monitoring platform;
S-B2: waiting for the response of the monitoring platform to the message to be transmitted to the monitoring platform and receiving the response transmitted by the monitoring platform;
S-B3: determining the number of the first sub-messages transmitted in batches for the first time and the capacity of the first sub-messages, and transmitting the first sub-messages according to the capacity of the first sub-messages;
S-B4: after the number of the first batch of sub-messages is transmitted to the monitoring platform according to the capacity of the first sub-message, the monitoring platform receives a verification instruction of transmitting and verifying the link of the GSM network by the controller;
S-B5: the monitoring platform receives the checking instruction for checking the link of the GSM network, executes judgment, transmits the response of the smooth GSM network to the controller when the GSM network is smooth, and the controller receives the response of the smooth GSM network of the monitoring platform;
S-B6: after obtaining the response of the GSM network unblocked returned by the monitoring platform, the controller determines the number of the first sub-messages transmitted in batches for the first time and the capacity of the first sub-messages and transmits the first sub-messages to the monitoring platform; repeating the steps until the message transmission corresponding to the message transmission capacity of the monitoring platform in the message to be transmitted to the monitoring platform is finished, and disconnecting the link by the controller and the monitoring platform respectively;
when the sub-message is transmitted again from the suspended position, the monitoring platform registers the number of bytes of the sub-message which is transmitted to the monitoring platform and corresponds to the stop point of the transmission;
S-B7: when the controller initiates the transmission operation of the message with the transmission stopped again, transmitting a command of transmitting again to the monitoring platform;
S-B8: the controller receives the response of the monitoring platform to the retransmitted instruction; the monitoring platform transmits the byte number of the sub-message transmitted to the monitoring platform to the controller in the order response of retransmission so as to enable the controller to transmit the message in batches from the transmission stopping position corresponding to the byte number;
S-B9: after obtaining the response returned by the monitoring platform, the controller determines the number of sub-messages transmitted in batches and the capacity of the sub-messages and transmits the sub-messages corresponding to the number of the sub-messages to the monitoring platform according to the determined capacity of the sub-messages until all the messages which are not transmitted are transmitted.
The monitoring platform stores the received message and registers the storage pointer of the message and the mark code of the message in the information table.
When the monitoring platform transmits the message transmitted to the monitoring platform to the controller, the method comprises the following steps:
S-C1: the controller transmits a message for transmitting the message transmitted to the monitoring platform to the controller to the monitoring platform, and the message for transmitting the message transmitted to the monitoring platform to the controller is provided with a mark code of the message, the capacity of the message to be transmitted to the controller, the number of sub-messages transmitted to the controller in batches each time and the capacity of the sub-messages transmitted to the controller by the monitoring platform; then the controller waits for the response of the monitored platform;
S-C2: after receiving the message for transmitting the message transmitted to the monitoring platform to the controller, the monitoring platform judges the message and transmits a response to the controller; the monitoring platform acquires a message storage pointer which requests the monitoring platform to transmit the message transmitted to the monitoring platform to the controller through the information table according to the mark code of the message, and searches the message which needs the monitoring platform to transmit the message transmitted to the monitoring platform to the controller according to the message storage pointer;
S-C3: after receiving the response of the monitoring platform to the message for transmitting the message transmitted to the monitoring platform to the controller, the controller executes the first batch of monitoring platform to transmit the message transmitted to the monitoring platform to the controller, and transmits the message transmitted to the monitoring platform to the controller sub-message from the monitoring platform batch monitoring platform according to the predetermined number of sub-messages for transmitting the message transmitted to the monitoring platform to the controller and the capacity of the sub-messages for transmitting the message transmitted to the monitoring platform to the controller;
S-C4: after receiving a batch of sub-messages, the controller transmits an instruction for checking the link of the GSM network to a monitoring platform;
S-C5: after the monitoring platform obtains the instruction transmitted by the controller for checking the link of the GSM network, the monitoring platform judges the current GSM network condition, and returns a response of the smooth GSM network to the controller when the GSM network is smooth; after the controller obtains the response of the smooth GSM network returned by the monitoring platform, the controller confirms that the link of the GSM network is smooth;
S-C6: and after the controller confirms that the link of the GSM network is unblocked, the monitoring platform is executed to transmit the messages transmitted to the monitoring platform to the controller again in batches according to the number of the sub-messages for transmitting the messages transmitted to the monitoring platform to the controller and the capacity of the sub-messages for transmitting the messages transmitted to the monitoring platform to the controller until the messages transmitted to the monitoring platform are transmitted to the controller.
Here, during the period that the monitoring platform transmits the message transmitted to the monitoring platform to the controller, the controller is prevented from being delayed from receiving another message and confirming that the controller has received the message because the controller is not receiving the message transmitted by the monitoring platform to fill up the temporary storage space; correspondingly, the controller also needs to transmit an instruction for checking the link of the GSM network to the monitoring platform to confirm whether the messages transmitted to the monitoring platform by the monitoring platform in batches are transmitted to the controller successfully or not; when the monitoring platform obtains an instruction for checking the link of the GSM network, the judgment is executed, and when the GSM network is unblocked, a response for unblocking the GSM network is returned; when the controller obtains the clear response of the GSM network, the controller confirms that the link of the GSM network is clear.
The invention also provides a method for stopping the monitoring platform to transmit the message transmitted to the monitoring platform to the controller and then continuously transmitting the message transmitted to the monitoring platform to the controller, in the invention, under the condition that the message capacity corresponding to the sub-message for transmitting the message transmitted to the controller to the monitoring platform by the controller is lower than the capacity for transmitting the message transmitted to the controller by the monitoring platform for stopping the message, the monitoring platform for stopping the message transmits the message transmitted to the monitoring platform to the controller for operation, and the number of bytes which is transmitted to the controller and corresponds to the stopping position of the controller for transmitting the message transmitted to the monitoring platform by the monitoring platform is registered; here, the stop position at which the monitoring platform transfers the message directed toward the monitoring platform to the controller is the stop position at which the controller transfers the message directed toward the monitoring platform to the controller.
When the operation of the suspended message transfer to the controller is executed again, the message which continuously transfers the message transferred to the monitoring platform to the controller is transferred to the monitoring platform, the message which continuously transfers the message transferred to the monitoring platform to the controller has the mark code of the message, the byte number of the message transferred to the controller, the number of sub-messages which transfer the message transferred to the monitoring platform to the controller in batches and the capacity of the sub-messages which transfer the message transferred to the monitoring platform to the controller are continuously transferred to the monitoring platform; the receiving monitoring platform transmits the message transmitted to the monitoring platform to the controller from the stopping position until the message transmitted to the monitoring platform is transmitted to the controller.
