Embodiment
For making content of the present invention more clear understandable, below in conjunction with Figure of description, content of the present invention is described further.Certainly the present invention is not limited to this specific embodiment, and the known general replacement of those skilled in the art is also encompassed in protection scope of the present invention.
Fig. 1 is the calcspar of warning message transmission system of the present invention, and below with reference to Fig. 1, the present invention will be described.
Warning message transmission system of the present invention for carrying out the transmission of the warning message that semiconductor technology produces between host computer and slave computer, and this transmission system comprises slave computer storage unit 10 and host computer reading unit 20.Warning message can comprise warning title, ID, and specific descriptions information produces position, generation time etc.Slave computer storage unit 10 comprises acquisition module 11, the first memory modules 12 and trigger module 13.Wherein, acquisition module 11 is for gathering warning message termly; The first memory module 12 is connected with acquisition module 11, and it comprises a storage space 12a, the warning message that this storage space 12a gathers for storage of collected module 11; Trigger module 13 is connected with memory module 12, and when storage space 12a is filled with, trigger module 13 sends trigger pip to the upper machine-readable unit 20 of getting.Host computer reading unit 20 comprises read module 21 and the second memory module 22.Wherein, read module 21 receives trigger pip, by this trigger pip, is triggered and is read at least one warning message in storage space 12a; The second memory module 22 is connected with read module 21, the warning message reading for storing read module 21.Preferably, read module 21 will read alarm generation time warning message the earliest in storage space 12a after receiving trigger pip.In addition, the quantity of the warning message that read module 21 reads at every turn can be one or more, and the present invention is not limited.Compared to prior art, the present invention is first preserved warning message by the storage space in the first memory module of slave computer PLC, after storage space is filled with, send again trigger pip and carry out the transmission of warning message, can guarantee that thus host computer all can read and preserve the warning message that collected each time, effectively avoid the loss of warning message.In order to guarantee that the warning message that storage space is stored when the slave computer PLC abnormal power-down can not lose, storage space 12a is preferably nonvolatile storage, as hold during power off register district.In addition,, in order to realize the preservation to warning message under the prerequisite of operation that does not affect slave computer PLC, the first memory module is preferably the internal memory of slave computer PLC, therefore no longer needs additionally to increase storage card, also can not increase equipment cost.
Next in connection with specific embodiment, the present invention is further illustrated.
The 1st embodiment
Figure 2 shows that the schematic diagram of the present embodiment warning message transmission system storage space 12a, Figure 3 shows that the process flow diagram of the present embodiment alarm information transmission method.
Please refer to Fig. 1 to Fig. 3, acquisition module 11 fixed cycle ground read the information of alarm detection element, and to gather warning message, once collect warning message, the first memory module 12 is deposited in storage space 12a.Read module 21 receives after trigger pip, reads alarm generation time warning message the earliest in storage space 12a.In the present embodiment, take read module 21, read 1 warning message describes as example at every turn.The first memory module 12 is deposited in storage space 12a according to the order of the alarm generation time of each warning message.Specifically, alarm generation time warning message is early stored in the upper address bits of storage space 12a, and the warning message in evening alarm generation time is stored in the low address position of storage space 12b, and vice versa.Please refer to Fig. 2, because acquisition time and the alarm generation time of acquisition module to warning message is basically identical, in Fig. 2, with acquisition time, represent the priority of alarm generation time.As shown in Figure 2, in storage space 12a, there is N address bit, the warning message that the warning message to the gathering for the 1st time gathers for N time is stored to low address position from upper address bits, when read module 21 receives trigger pip and will carry out reading of alarm generation time warning message the earliest, only need read the warning message of highest address bit in storage space thus.It should be noted that, the warning message that the warning message to the gathering for the 1st time in other embodiments gathers for N time can be also to store to upper address bits from low address position, and when read module reads multiple warning message at every turn, read the highest warning message of multiple address bits in storage space.
In this enforcement, being stored as of warning message starts storage from the low address position of storage space according to the order of alarm generation time, and the new warning message gathering is always stored in the address bit of lowest order.Therefore,, when acquisition module collects new warning message, in storage space 12a, the warning message of original storage is successively to its address bit transmission the storage of high one.As shown in Figure 2, after the warning message that the address bit of storage space is all gathered by N time takies, trigger module 13 sends trigger pip to host computer, and read module 21 will read the warning message gathering for the 1st time of storing in highest address bit, and is deposited in the second memory module of host computer.Afterwards, judge whether the operation of slave computer PLC finishes, if finish the end of transmission (EOT) of warning message; If operation does not also finish, proceed the transmission of warning message.In Fig. 2, acquisition module 11 collects warning message (warning message gathering for the N+1 time) again, the warning message of storing in storage space 12a is successively to its address bit transmission the storage of high one, and the warning message gathering for the N+1 time is deposited in minimum address bit.The warning message that so the 1st time in highest address bit gathers covers the warning message being gathered by the 2nd time, stores the warning message gathering for the 2nd time to the N+1 time in storage space 12a.Because storage space 12a now remains the state of being filled with, trigger module sends trigger pip to host computer, and delivery piece 21 will read the warning message gathering for the 2nd time of storing in highest address bit, and be deposited in the second memory module of host computer.
The 2nd embodiment
Figure 4 shows that the schematic diagram of the present embodiment warning message transmission system storage space 12a, Figure 5 shows that the process flow diagram of the present embodiment alarm information transmission method.
In sum, warning message transmission system of the present invention and transmission method, by the storage space of store alarms information is set in slave computer, when storage space is filled with, sending trigger pip makes host computer carry out reading of warning message, avoided because of host computer read cycle and slave computer warning message collection period is inconsistent and slave computer is not preserved the warning message that warning message causes and lost, thereby guaranteed that warning message can more fully be recorded.
Although the present invention discloses as above with preferred embodiment; so described many embodiment only give an example for convenience of explanation; not in order to limit the present invention; those skilled in the art can do some changes and retouching without departing from the spirit and scope of the present invention, and the protection domain that the present invention advocates should be as the criterion with described in claims.
