Embodiment
The title that the utility model is related to explanation in advance.
Programmable logic controller (PLC) (Programmable Logic Controller, PLC), it adopts a class programmable memory, be used for its internally stored program, actuating logic computing, sequential control, regularly, user oriented instructions such as counting and arithmetical operation, and control various types of machineries or production run by numeral or analog I/O.
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated.
Fig. 1 has shown an example of the utility model zymotechnique production equipment monitor message communication system, and production equipment is the zymotechnique of brewageing for food, comprises fermentation tank and auxiliary device thereof.Zymotechnique production equipment monitor message communication system shown in Figure 1 comprise as the master controller at production management center and be arranged on the described production equipment from device controller.Master controller also is connected with host computer.Host computer is the general designation to the higher level management system, mainly refers to equipment that master controller is managed, and master controller receives the control command that host computer is sent to the status information of host computer transmission production equipment.
Master controller is connected with first wireless communication module, is used for sending and receiving monitoring and control information (abbreviating monitor message as).
Comprise according to concrete task from device controller: industrial control unit (ICU) PLC, the human-computer interaction terminal terminal of touch panel display device (as be provided with), power-equipment controller and/or instrument.Be connected with the zymotechnique production equipment from device controller, be used for obtaining the control information that the running state parameter of zymotechnique production equipment and reception and processing come autonomous controller.The control information that master controller is sent can convert control command to production equipment is directly operated, and also can control command be shown by display terminal, according to circumstances carries out suitable operation by operating personnel.Be connected with second wireless communication module from device controller.First wireless communication module and second wireless communication module carry out communication in the mode of wireless telecommunications.By the said system structure, can realize master controller and transmit from the monitor message between the device controller.
In order to reduce master controller to the complexity of production equipment control procedure, zymotechnique production equipment monitor message communication system of the present utility model has adopted the method that poll group is carried out the poll communication of dividing.What the production equipment among Fig. 1 in the frame of broken lines connected is same poll group from device controller.Specify as follows.At first, what will be connected with fermenting and producing equipment divides into groups from device controller, and after grouping finished, master controller will carry out the poll communication by second wireless communication module from device controller in first wireless communication module and the poll group.The method of above-mentioned grouping comprises: will have the operation incidence relation production equipment be divided into a poll group from device controller.The operation incidence relation here refers to that in technological process the operation that the zymotechnique production equipment carries out has relevance, and in the process time clear and definite restriction is arranged.Process time requires mainly in two kinds of situation: a kind of is that individual equipment carries out multi-pass operations, has the time limit requirement between each operating process, such as mixing plant, need carry out repeatedly, and strict regulation is arranged each interval time of stirring; Another kind of situation is that operating process has the time limit requirement, adds water after stirring between the different production equipment, and stirring operation and the time interval that adds between the water operation should meet technological requirement.
After being divided into poll group, master controller is to carrying out periodic polls from device controller in the poll group, and the concrete course of work is referring to the explanation to Fig. 2.Poll sequencing in the cycle of poll and cycle should require coupling with the above-mentioned process time.Concrete following two aspects (two kinds of situations that require at the above-mentioned process time) that comprise:
The first, in the time range that the described described production equipment operation that connects from device controller limited in polling cycle was set in described group.
This situation is primarily aimed at single equipment and carries out multi-pass operations, and there is technological requirement in the time interval between each operating process, and then the cycle of poll or several cycles must meet technologic time requirement.For example, stirring with the interval time of stirring for the second time for the first time is 10 minutes, and then polling cycle is 10 minutes, or certain integral multiple of polling cycle is 10 minutes.
The second, in described polling procedure, the described time interval from device controller that two described production equipments of poll connect meets the time interval that these two described production equipment operations limit.
This situation is primarily aimed between the operation of different fermentations explained hereafter equipment has sequence requirement, should meet technological requirement the interval time between the operation simultaneously.Add water after for example stirring, stirring operation and the time interval technological requirement that adds between the water operation are 8 minutes, and stir production equipment and add the water production device branch in same poll group, then in one-period, poll stirring production equipment and the time interval that adds between the wetting system should be 8 minutes, and perhaps certain integral multiple cycle adds that poll stirring production equipment and the time interval that adds between the wetting system should be 8 minutes.
The method of above-mentioned division poll group also comprises: what production equipment of the same type connected divides in same poll group from device controller; Or of the same typely divide in same poll group from device controller; According to the existing qualifications (for example " first " of aforementioned polling cycle and poll order and " second ") of polling cycle, adjust production equipment and enter into poll group, to meet the existing qualifications of polling cycle.The method priority application of dividing poll group aforesaid " is connected with the described production equipment with operation incidence relation described be divided into one group from device controller ", aforesaid additive method is then selected application according to physical condition.This is the method that those skilled in the art can know, and repeats no more.
In order to implement technical solutions of the utility model more efficiently, preferred pin arranges first wireless communication module to a poll group, and namely first wireless communication module is corresponding one by one with described poll group.
Do not influence the communication of other poll group for fear of the communication of poll group, the communication frequency of different poll group (communication frequency between first wireless communication module and corresponding second wireless communication module) is different.Table one has provided the example of a poll group communication frequency.
Table one
Fig. 2 has shown the course of work of the utility model zymotechnique production equipment monitor message communication system.
At first, provide in the described polling procedure described master controller and described formula from device controller communication time T:
T≥t1+t2+t3+t4+t5+t6+t7+t8
Wherein, t1 is the maximum time of main operation controller corresponding program;
T2 is the time that master controller generates information to be sent;
T3 sends the information required time from described first wireless communication module to described second wireless communication module;
T4 describedly changes required time from device controller with the information that receives;
T5 is described from device controller operation corresponding program required maximum time;
T6 is the described time of waiting the information of uploading that generates from device controller;
