On-off model is transmitted in the form of data packet close to switch the processor of emitter, then the place of emitter Reason device is equally transmitted to on-off model by wireless communication module the number of ground Coke-pushing Management System in the form of data packet According to library server；
In addition the processor of emitter by wireless communication module earthward Coke-pushing Management System database server send out It also carries out executing disposition to the message of lost data packets during penetrating on-off model, which includes sequentially executing as follows Measure：
The critical value for the lost data packets that the processor of reduction emitter is equipped in advance；Differentiate that the processor of emitter passes through Wireless communication module earthward during the database server emission switch amount signal of Coke-pushing Management System data packet either with or without There are lost data packets；If there are lost data packets, the number of lost data packets at this time is just obtained；Data are lost in differentiation at this time The number of packet is either with or without the critical value more than lost data packets；If more than the critical value of lost data packets, just display module is passed It send the message of lost data packets at this time and shows the message of the lost data packets on display module.
Detailed description are as follows for the critical value for the lost data packets that the processor for reducing emitter is equipped in advance：
It is executed specifically in the mode of the critical value for the lost data packets being equipped in advance to the processor for reducing emitter Before bright, the aspect that involves of method that disposition is first executed to the message of lost data packets is done and is illustrated：
The data dead is that the processor of emitter passes through the database of wireless communication module earthward Coke-pushing Management System Server emission switch amount signal data packet transmission has some setbacks, that is, data dead state；
Lost data packets are that the duration that each data packet is read is more than that normal data packet reads the state occurred when duration.It must note Meaning be lost data packets is to lead to the cause of data dead, that is, lost data packets can make data dead.Therefore to Data discrimination dead state must obtain the message of lost data packets.Here the message of lost data packets includes lost data packets Such message at the time of the number of message, the number of lost data packets, lost data packets.The message of each lost data packets Number is unique identifier.
The target of the critical value for the lost data packets that the processor of reduction emitter is equipped in advance is must be to display module Transmit the message of a greater amount of lost data packets.As can once be lost in the processor of emitter in specific use Lose data packet, i.e., it is such at the time of can be the number, the number of lost data packets, lost data packets of the message of lost data packets The message of lost data packets writes into the internal memory that processor is equipped with.If the critical value for the lost data packets being equipped in advance is 28, that is, emitter processor can not go to obtain lost data packets lost data packets of the number no more than 28 news Breath also can not just transmit the message of such lost data packets to display module.
Then because of the message of the deficient such lost data packets of worker, can to understand the state of data dead inadequate Correctly.
It is described differentiate emitter processor by wireless communication module earthward Coke-pushing Management System database take Data packet is either with or without the mode for lost data packets occur during business device emission switch amount signal：
Equally on-off model is transmitted by wireless communication module in the form of data packet in the processor of the emitter To the database server of ground Coke-pushing Management System operation when, the duration that also each data packet of synchronization monitoring is read, and same The mode that step monitors the duration that each data packet is read includes：And the place that the mode that each data packet is read is the emitter The activation program managed in device sends out an activation instruction, then reads the data packet by the activation instruction；Setting activation program is sent It was the first moment at the time of going out an activation instruction, when being second at the time of then reading data packet completion by the activation instruction It carves, it is exactly the duration that the data packet is read to subtract the difference obtained by the first moment with the second moment；
Equally on-off model is transmitted by wireless communication module in the form of data packet in the processor of the emitter To ground Coke-pushing Management System database server during normal operation, when a length of reading number that each data packet is read According to the normal reading duration of packet, if more than the normal reading duration of data packet, illustrate lost data packets be in the presence of, it will The processor for emitter occur passes through the database server emission switch of wireless communication module earthward Coke-pushing Management System Amount signal data packet transmission has some setbacks, that is, data dead state；The size of the number of lost data packets in this way is bigger, number Severe situation according to the situation of stagnation is also severeer, that is, the size of the number of lost data packets is bigger, data dead Situation is severeer；And the processor in emitter passes through the data of wireless communication module earthward Coke-pushing Management System The target for also carrying out executing the message of lost data packets disposition during the server emission switch amount signal of library is to showing mould Block transmits the message of lost data packets at this time and shows the message of the lost data packets on display module, so just must first sentence Not either with or without lost data packets occur, if the duration that data packet is read is more than the normal reading duration of data packet, it just will appear and lose The situation of data packet is lost, so just using the normal duration that reads of data packet as the duration of the read data packet set, thus, it is possible to It is enough via differentiating duration that data packet is read either with or without differentiating either with or without going out active more than the normal reading duration of data packet If data packet illustrates lost data packets be in the presence of, goes in S1 and execute more than the normal reading duration of data packet；If It is less than the normal reading duration of data packet, illustrates be not in the presence of lost data packets, goes in S4 and execute；
S1：If there are lost data packets, the number of lost data packets at this time is just exported；
The method of the export number of lost data packets at this time is：The reading for the duration divided by setting that just first export data packet is read Take the quotient of the duration of data packet；Then the numerical value obtained after the quotient being carried out rounding processing is as lost data packets at this time Number；The number of lost data packets at this time is obtained with this；For example, the duration that data packet is read is 0.02218s, the reading of setting The duration of data packet is the normal 0.01109s for reading duration for data packet, then the number of lost data packets is exactly at this time Two.
S2：Differentiate the number of lost data packets at this time either with or without the critical value more than lost data packets：
After obtaining the number of lost data packets at this time, via differentiating that the number of the lost data packets at this time wants either with or without setting is reached It asks to determine the message that should transmit lost data packets at this time or not to display module；Here sets requirement is that this loses data at this time The numerical value that the number of packet obtains after the critical value more than the lost data packets that the processor for reducing emitter is equipped in advance, If the numerical value obtained after the critical value for being more than the lost data packets that the processor for reducing emitter is equipped in advance, branches to It is executed in S3；If being obtained after being less than the critical value for the lost data packets that the processor for reducing emitter is equipped in advance Numerical value is branched in S4 and is executed；
S3：If the number obtained after the critical value for being more than the lost data packets that the processor for reducing emitter is equipped in advance Value just transmits the message of lost data packets at this time to display module and shows the news of the lost data packets on display module Breath;
If the numerical value obtained after the critical value for being more than the lost data packets that the processor for reducing emitter is equipped in advance, just Show that this transmits the message of lost data packets at this time to display module and shows the news of the lost data packets on display module Breath, that is, the message of the lost data packets is first obtained in the processor of emitter；
In the processor of emitter, the message of lost data packets is stored in the internal memory that the processor is equipped with, institute The message of the lost data packets can be relied on to be stored in the pointer in the internal memory that the processor is equipped with, and lost via this The message for losing data packet is stored in the message that lost data packets at this time are taken out in the processor, then at this time to display module transmission The message of lost data packets and the message that the lost data packets are shown on display module；As the message of lost data packets In the numbers of lost data packets be stored in some region in the internal memory that the processor is equipped with, via the region Pointer can obtain the number of the lost data packets in the region corresponding to the pointer, then in the aobvious of the processor of emitter Show the number that the lost data packets are shown in module.
S4：If the duration that data packet is read is less than the normal reading duration of data packet, or lost data packets at this time Number is less than the critical value of lost data packets, and the message of lost data packets at this time is not just transmitted to display module；
In addition the message of the lost data packets be stored in a manner of byte stream emitter processor be equipped with built in In memory, and the internal memory that the processor of emitter is equipped with is stored in a manner of byte stream to display module transmission In lost data packets at this time message.
If the duration that data packet is read is less than the normal reading duration of data packet, show do not have in the processor of emitter It there are lost data packets, the message of lost data packets is also just not present, that is, need not at this time be lost to display module transmission Lose the message of data packet.
If the number of lost data packets is less than the critical value of lost data packets at this time, show the news of lost data packets at this time Breath does not meet the requirement that the message of lost data packets at this time is transmitted to display module, so also just not transmitted at this time to display module The message of lost data packets.
Pass through the database service of wireless communication module earthward Coke-pushing Management System via the processor in emitter Also carry out executing disposition to the message of lost data packets during device emission switch amount signal, the method for disposal include it is following sequentially The measure of execution：The critical value for the lost data packets that the processor of reduction emitter is equipped in advance；Differentiate the place of emitter Data during device is managed by wireless communication module earthward the database server emission switch amount signal of Coke-pushing Management System It is surrounded by and lost data packets does not occur；If there are lost data packets, the number of lost data packets at this time is just obtained；Differentiate at this time The number of lost data packets is either with or without the critical value more than lost data packets；If more than the critical value of lost data packets, just to aobvious Show that module transmits the message of lost data packets at this time and shows the message of the lost data packets on display module.In addition described The message of lost data packets is stored in a manner of byte stream in the internal memory that the processor of emitter is equipped with, and right The loss at this time in the internal memory that the processor of emitter is equipped with is stored in display module transmission in a manner of byte stream The message of data packet.The critical value for the lost data packets being equipped in advance via the processor for reducing emitter in this way, in addition its Its mode obtains the message of more complete lost data packets, improves the correctness that the situation of data dead understands with this.
