Abstract
An automated process control system (100) and method includes a controller (101) and a number of peripheral devices (104) that are controlled by the controller (101). The devices are located in a number of environments and sub-environments. The devices, environments, and sub-environments are organised in hierarchies and each device has an associated hierarchical identifier, which depends upon the environment in which the device is located. If the environment changes then so does the associated identifier. The controller is operable to determine when an environment changes and to implement any control actions that may be required by the change in the environment. The identifier for devices can also be linked to users of the system to define dependencies between the devices and users. Properties for the devices can therefore be linked to the users through the identifier, thus enabling multiple users to access the same devices.

In the scope of broad sense, the present invention relates to a process control system that externally is provided in the environment (suitable, as also to comprise subenvironment), comprise a plurality of distinct devices that multiple function is provided in this system.
Fig. 1 has described an example of process control system 100, and process control system 100 comprises a controller 101, for example a computing machine or other suitable Programmable Logic Controllers, and processing control apparatus (process control equipment) 103.This processing control apparatus 103 comprises possible such as sensor, gearing (actuator) and transducer peripherals 104 such as (transducer), it responds the signal of self-controller 101 and operates, and also can be operated to provide data with suitable manner to this controller 101 according to its function simultaneously.By this way, thus this controller 101 can be operated to provide an automated system according to demand control, operation and response apparatus 104.These equipment 104 can have the trigger condition that is linked with equipment, and these conditions make equipment 104 its functions of performance according to default control action when being activated.These peripherals 104 are connected in this controller 101 in any suitable manner, for example by known network wireless agreement, internet or Ethernet.
It is known that the processing controls that is used to handle robotization is used, like this, except content related to the present invention and, remaining just needn't do any more detailed description here.
These equipment 104 are arranged in needed external environment condition, and can be operated with described controller 101 and communicate by letter in any suitable manner.
Typically, this controller 101 is connected in such as user interfaces such as keyboard 105, visual display 106, this user interface also has, for example touch-screen.This controller 101 also comprises a processor 107 and storer 108 (comprising one or more databases 109), and these devices are known to those skilled in the art.This controller 101 is programmed to allow the described process control system 100 can be according to being operated like that of will being described in detail later.
In described process control system 100, environment that is provided within it and equipment 104 are organized by the mode with stratification, with the person of assisting management management and the configuration equipment as process control system, so that the flexible and useful control function of its performance.In fact, this realizes that in controller 101 these contents will be described in further detail below.
Depend on other equipment and the trigger condition thereof of being subscribed, these equipment 104 can have control action.Control action also can depend on equipment 104 residing environment.
Each equipment 104 has the sign of the corresponding stratification of define equipment according to its environment and subenvironment.The sign of this stratification is generated and is stored in controller 101, and the control sequence that allows to comprise one or more equipment by the dependence between define equipment and its trigger condition is established.Change in environment (and correspondingly its sign) can trigger action and/or an action sequence under the control of controller 101, be initialised.In the middle of control action carried out, the information of relevant devices type, operating parameter and characteristic that it has can be linked to stratification information and be stored in this controller 101.The configuration data that is used for an equipment can comprise the position of environment or equipment, diagram expression (pictorial representation), correction parameter (calibration parameters), control sequence, triggering thresholding and to the dependence of other equipment.Such example comprises the picture of equipment or is used to be read (, if the words of sensor) or the operation of be activated (, if transponder) and the parameter of correction.
Each equipment 104 can be a physical equipment, such as sensor, switch or valve (valve), perhaps can be the virtual unit that adopts the part computing method to be modeled and to be implemented in controller 101.Such virtual unit provides the dirigibility of very big increase.For example, they can represent the switch that is activated by the picture on the touch-screen, and time delay or clocking capability perhaps are provided.They can be before the operation of equipment or assessment be initialised, the dependence of the logical collection of indicated condition (perhaps by the dependence on device trigger condition and other equipment, perhaps by the definition of program logic computer state).They also can be used for test purpose and replace physical device provisionally.Such virtual unit can be used as real equipment and is organized in system and the environment in the mode of stratification.
Equipment can also be people, animal or any other object, and the term that can correspondingly be explained, and equipment can also be counted as the environment of other equipment.
As mentioned above, equipment 104 is associated to the environment of stratification tissue.Each environment can represent the image or the picture of this environment, and apart (spatial separation), topology tissue and store with respect to the geographic position of other environment mode with stratification.When these information can be with respect to other environment and equipment 104, can also adopt geographic coordinate (geographicalcoordinates) that it is determined utterly.
Replacedly, the equipment 104 of aforementioned stratification tissue and their control information can be defined by other conventional apparatus, for example comprise the database of the separation that comprises same information basically by visit.
Further, the relation between the many levels of equipment 104 can manually or dynamically change, and this itself can trigger robotization action or new robotization sequence.
With reference to foregoing, the special case of describing common characteristics (general features) now is to further describe the present invention.Be described in the example of Fig. 2 at this, a process control system 1 is provided, this process control system 1 is among the aquatic products operation (aquaculture operation) (Acme fishery), and this aquatic products operation is included in the office building 2 on the one real estate and produces builder's temporary shed (production shed) 3.Produce builder's temporary shed 3 and comprise 6 tanks 4,5, wherein hatchery 4 is used to hatch fish, breed pond 5 is used to culture fish.For clarity sake, two tanks only shown in Figure 2, each tank comprises a plurality of equipment 6 such as oxygen pump (oxygen pump), and it comprises a water flow sensing unit (flow sensor), an oxygen sensor (oxygensensor), a temperature sensor, a pH value sensor in the pump.Tank 4 is connected by valve 9 with 5, and this valve allows fish to walk between two ponds.Near each outlet of valve 9 a RFID transmitter (not shown) is arranged, it can detect the situation that fish passes through, and the position of discerning this fish and determining this fish this moment.Described builder's temporary shed 3 also comprises the equipment 6 such as 4 safety sensors, 4 lamps and 7 security cameras, component devices 6 such as all these sensors, pump, lamp and camera, and all be connected to controller 7 and send and received signal in appropriate mode.Among Fig. 2, for clarity sake, the equipment 6 of some has only been described.
2a of office and the back 2b of office before office 2 is divided into.2a of office and 2b have a lamp and a safety sensor, and preceding office also comprises a camera.These lamps, safety sensor and camera also are equipment 6 of the present invention.
Environment of organizing by the stratification of some and the equipment that is connected in described environment are described the present invention.
Environment: Acme (fishing ground)
Equipment: all Acme had or its real estate on equipment.
Environment: real estate 1 (subenvironment of Acme)
Environmental labels is Acme: real estate 1:
Equipment: 4 safety sensors, 4 lamps, 7 cameras, 6 lambda sensors, 6 temperature sensors, 5 RFID transmitters, 6 fish valves, 6 pH value sensors, 6 oxygen pumps, 6 water flow sensing units
Environment: office building (subenvironment of real estate 1)
Environmental labels is Acme: real estate 1: office
Equipment: 2 safety sensors, 1 camera, 2 lamps
Environment: office front portion (subenvironment of office building)
Environmental labels is Acme: real estate 1: office: front portion
Equipment: camera, lamp, safety sensor
Wherein each equipment is identified uniquely, for example by its title and stratification environment.
Environment: office rear portion (subenvironment of office building)
Environmental labels is Acme: real estate 1: office: rear portion
Equipment: lamp, safety sensor
Environment: (production) builder's temporary shed (subenvironment of real estate 1)
Environmental labels is Acme: real estate 1: builder's temporary shed
Equipment: lamp 1, lamp 2, preceding safety sensor, back safety sensor
Environment: hatchery (subenvironment of builder's temporary shed)
Environmental labels is Acme: real estate 1: builder's temporary shed: hatchery
Equipment: lamp, camera, lambda sensor, temperature sensor, pH value sensor, oxygen pump, water flow sensing unit, fish valve, camera
Environment: growth pond 1 (subenvironment of builder's temporary shed)
Environmental labels is Acme: real estate 1: growth pond 1
Equipment: lamp, lambda sensor, temperature sensor, pH value sensor, oxygen pump, water flow sensing unit, RFID transmitter, camera
Can repeat above-mentioned last example at 4 growth ponds of remainder.
As can be seen, each equipment is described uniquely by the level of its title and its environment.
For water flow sensing unit, they can by logically as shown in FIG. be connected in tank like that.
Preferably, because water flow sensing unit is the part of pump, so it can be counted as the equipment in the pump environment, promptly the equipment of pump is the environment that can connect other equipment.In this case, environment can be defined as Acme: real estate 1: builder's temporary shed: growth pond 1: oxygen pump: and equipment is water flow sensing unit.
A stratification scheme like this can reach required any degree of depth.
Extraly, if every fish is mounted a RFID label, just this fish can be looked at as an environment so, this environment self comprises the equipment (RFID label) with unique sequence number.In this case, environment can be a salmon: the RFID label: equipment (#000100), wherein #000100 is the series number of RFID label.If known its is in growth pond 1: environment is exactly Acme: real estate 1: builder's temporary shed: growth pond 1: salmon: RFID label: RFID is the equipment of #000100.
Be convenient meter, if hypothesis RFID label is represented a fish with RFID label, (being convenient meter) selectively is punctured into Acme with environment so: real estate 1: builder's temporary shed: having the RFID label is the growth pond 1 of the equipment of #000100.
For example, when between tank, moving about with response fish opening of valves, can estimate size and the weight of fish by analyzing by the picture of camera and the position of determined fish for response control mehtod fish opening of valves and fish.
When detecting position change, their environment can dynamically change.For example:
Swum over to growth pond 1 if the RFID label is the salmon of #000100, in the process of moving about, this moves the RDID sensor that is positioned at first tank inlet and arrives, and so, process control system 1 just knows that this salmon has entered a new environment.
One has new environment, and corresponding new environmental labels, dynamically associating of equipment can be used as the triggering that certain specific control system changes.For example, at fish, a different feeding circulation can be triggered.The motion that the fish of sufficient amount passes valve can reset to the feedback thresholding lower numerical value, and reset counter, to continue to increase feeding based on the duration or to the estimation of fish size.
Described environment stratification sign can be used to the relation between define equipment and the related trigger condition, it is dependence, so that can causing equipment, process control system 1 operates to respond the change in other equipment, for example, with reference to top description, swim over to another environment certain bar fish (first equipment) from an environment, then this fish just has an altered environmental labels, and this sign can processed control system 1 (particularly controller 7) determine whether this change triggers an automatic feeding equipment (another equipment of control system 1) and correspondingly operate according to a default feeding cycle.
And, gps coordinate can be additional to equipment and/or environment in level.These gps coordinates (for fixing environment or equipment) can be static, or as be connected in system an environment (for example, moving vehicle) in or be dynamic during the output of the GPS equipment of another equipment.Any other equipment that this GPS equipment can be taken as in the system is equally treated.
Be readily appreciated that, in this embodiment, the invention provides a flexible way that is better than being generally used for the existing method of PLC and other opertaing devices, and, it is also understood that, such stratification control method makes people be more prone to management, because it is relevant to the form of thinking of equipment in the environment with people, and these equipment are affixed in the logical organization environment that can be connected to geographic coordinate.
Further, be readily appreciated that described the present invention can be applied to many other traditional industries control scenes abstractively, production line for example, but also can be used for many application that do not realize robotization now.For example, fish is used as equipment and has given a RFID label, and is same, and a people has such as the entrained mobile phone or the environment of computing machine.
In another embodiment of the present invention, process control system can be used to get in touch a people, communication and interference (intervention) in the feasible reason of management control activity effectively.In some process control systems, because multiple reason is necessary to relate to operator or user.
In existing equipment, at Installed System Memory in the place of depositing contact details so that can relate to someone when needed, for example by mobile phone, pager or Email, respond certain problem or information be provided.For example, one or more Mobile Directory Number can be stored, make short message service (SMS) message can be sent to first telephone number.If do not respond, then dial second mobile phone, the rest may be inferred.
Here just some problems have appearred, and the first, not every people has available communication facilities, sometimes may be at these equipment of a plurality of shared among users; The second, not every people near particular device, therefore may need to attempt a plurality of equipment; The 3rd, may need to notify the several people by process control system.May need to send a plurality of contact details, for example send to 3 people by email synchronization, perhaps contact sequentially, for example get in touch Adrew earlier,, get in touch Bruce then if in 10 minutes, there is not echo (for example using equipment) as timer, and not every contact method all is suitable for everyone, for example,, just dial its family's landline telephone if do not have echo in two minutes by pager contact Andrew.Can see, have many kinds of substitute modes, and in order to reach maximum effectiveness, need a kind of general solution cover the situation that might expect.
The present invention can realize top requirement in the following manner:
1. the people is used as (manually input and output response) equipment and treats, maybe ought act on the environment that allows the communication facilities of communicating by letter with the people;
2. the equipment of different communication equipment being used as stratification;
3. dynamically change contact method and instruction according to individual position and equipment.
In order to describe a last example, adopt the process control system 1 of existing embodiment, suppose that the oxidation furnaces in aquatic products pond has quit work, the operator must promptly be reminded.In the shift work arrangement of a complexity, may relate to a plurality of operators, if one can not be got in touch with, just must contact second or the 3rd operator.They may have different contact methods (for example pager, mobile phone, computing machine (by Email or instant message) or landline telephone (speech or keypad tone (touchtone)), and not every operator has such equipment.In order to increase the complicacy of present embodiment, suppose that they share a pager or mobile phone, and when changing shifts, join.
Such signal can be easily be stored in database or the catalogue so that it can be imported into automatic system in the mode of stratification in advance, perhaps imports these information with manual mode in advance.By way of example, can define unique sign in the following ways:
Environment:
Sign-Acme: technician: real estate 1:Andrew:
Equipment: mobile phone: short message service (sms), mobile phone: voice, mobile phone: keypad tone, pager, computing machine: keyboard, loudspeaker
Notice that mobile phone itself can be regarded the environment of SMS as, speech and keypad tone equipment can be described uniquely by its telephone number.
Environment:
Sign-Acme: technician: real estate 1:Bruce:
Equipment: mobile phone: short message service (sms), mobile phone: voice, mobile phone: keypad tone, pager, computing machine: keyboard, loudspeaker
Environment:
Sign-Acme: supvr: real estate 1:Colin:
Equipment: mobile phone: short message service (sms), mobile phone: voice, mobile phone: keypad tone, pager, computing machine: Email, computing machine: keyboard, loudspeaker
By this way, the people can be counted as being used for the environment of equipment (communication facilities of present embodiment), and each equipment is all to related with it configuration and programming response.Be appreciated that the preceding method that has above-mentioned distribution by employing, every type equipment is provided with and writes appropriate " driving ", can set up in the mode that Any user needs and control flexibly and respond.
For example, A (ndrew), B (ruce), C (olin) breeds fish and oxygen pump quits work, A and B have 16 hours at the scene every day, but nobody is working at night, people on duty can be periodically from A, B and C, select one as first night the contact person mainly be responsible for, perhaps change contact person at this first night weekly.Other two people will be near the scene, and should at first notify them with problem but by day.For example, if A is called out (share pager, and each member having same paging acknowledgment), if but in 10 minutes, do not respond this alarm, just can call out B with note (SMS) mode; But the problem based on occurring will send e-mails to all personnel.Alarm method periodically can be used in all three philtrums, after attempting to get in touch all three people, also not receive response simultaneously, also can take additive method, for example open welding bottle to stop fish death.
Adopt above-mentioned unique identification, people and real estate 1 are environmentally hazardous, this means, need not dial their landline telephone when the people is on the scene, and adopt loudspeaker as first mode to their alarm.Preferably, (such as the changing shifts or the change of position) or automated manner (for example right sensors or the transmitter by adopting GPS or RFID and people to carry) change when environmentally hazardous manually, and controller 7 can be operated to determine to be identified at timing changing.For example, can call out landline telephone (landline) or family's landline telephone of the 2nd Acme real estate (real estate 2), if for example A is in now, environment is exactly Acme so: the technician: the dwelling: Bruce, equipment are exactly mobile phone: note (sms), mobile phone: voice, mobile phone: keypad tone, pager, landline telephone: keypad tone, landline telephone: voice.
Can correspondingly change described control action.The people that loudspeaker apparatus is not suitable for needing contact is in the situation at the scene of real estate 1, and still, fixed telephone number can be used as and is controlled to people that contact is fit to locking equipment really.
The present invention can set up in simple mode, but may be because the actual needs of some of the staff's work also can have operation very flexibly.The worse scheme of other dirigibilities may cause the inconvenient remedial action (for example opening welding bottle) that maybe may cause costliness in the time of mistake, and can cause more inconvenient and expensive expense afterwards when really needing.Adopt convenient and correct relationship type, the triggering that can not produce mistake, and can in the middle of it uses, cultivate and trust, make each alarm all be treated gravely, and can not be the system of individual " wolf has come ".
Further, can set in advance such key-course for the operator, make and to come assisting users to adopt manual mode by simple user interface comparatively, perhaps the mode that imports by person on duty is set up behavior common, that be scheduled to.The user can also continue the more complicated behavior of configuration outside this predetermined scheme.
Can the present invention be abstracted into many other common situations not difficultly, for example, described control action can be walk about in the room of people in the house cause, and be associated with different room (environment), open or turn off equipment such as lamp.In such embodiments, this people in varying environment, the position is with the equipment of environment change.

Can repeat example for other 4 growth ponds.Be appreciated that each equipment described by its title and environment level thereof.
Such stratification scheme can be according to the required degree of depth arbitrarily that reaches.
In this embodiment, the stratification tissue of environment and the equipment that wherein provided can be used to allow a plurality of different people's access means (and any data that produce) to realize the target of control and robotization.The target of this control and robotization comprises monitoring, promptly determines current state or condition, log (logging), and state before promptly determining, and control promptly reached before dynamic response and work as precondition.
In this example, each equipment is owned by a people, and is perhaps total by a plurality of people when wishing.An owner can authorize, the authority that for example changes device characteristics is authorized read access or when comprising the equipment of output (in output time or) write-access with sweep equipment or when comprising the equipment of input (when the input or), under the assistance of other functions of process control system 1, this can realize on controller 7.
An owner can select " advertisement " to notify other people this equipment available or hiding this equipment of selection.Authority can based on people user one by one managed with or manage with the form of group for convenience, perhaps can unite these methods of use.
Each user's authority is associated with each unique stratification equipment or environmental labels in appropriate mode, make them to list individually and to be stored in the controller 7 according to association identification, perhaps the database that is linked in separation with a kind of alternative with management can access device 6 personnel.
By following method, process control system 1 can be operated to permission and control action are linked in the stratification sign to realize the control and the robotization of equipment.
Consider that many people may need the situation by the equipment access information.A plurality of researcher A (ndrew), B (ruce) and C (harlie) are implementing experiment, and D (onald) is the apparatus manager, and E (dward) is apparatus manager assistant, and G (reg) is aquatic products businessman (commercial aquaculturalist).
A, B and C respectively have its oneself growth pond, be responsible for its experiment separately and also use the growth pond, but they may share the hatchery, because this only needs less service time.
In traditional PLC system, the viewpoint of the system scope of the control problem of Xie Jueing as required, total system will be used as control system and programme.This is not suitable for research environment, because the control problem of experimental provision often changes.
Need one flexibly system implement experiment, and the data of equipment and control function are shared and management by different people.Not every people has equipment 6, but they are benefited in the mode of sharing some equipment.For example, air temperature sensor equipment can and have by the D installation, but is calibrated by E.A, B and C may obtain data for their experimental data by the visit air temperature sensor.Typically, any all is endowed ownership and control to the equipment in their each growth pond among A, B and the C, but when their fish is hatched, needs to visit the equipment in the hatchery at least.They not necessarily have in these equipment of calibration the occupation of any or have the knowledge of this respect, and this may be the occupation of E, and he has the authority of finishing this part thing.That A, B and C wish to use is rotatable, the camera of inclination and zoom, with its part as their experiment, focuses on tank off and on and monitors fish, so this is a shared device.A and B may do experiment on a kind of fish, may wish to share their data.C may not wish to share his data with A or B doing secret experiment.May need to control globally light with simulate day and night, the time of the opening and closing of light then is to A, B and all useful data of C.
The characteristic of system, the system that is provided to make has more flexibility and useful to the multi-user such as permission, control and feature.In the present embodiment, defined user and relation between the equipment are link (link) between equipment (and their characteristic) and the user.These characteristics adopt the stratification sign that equipment, their characteristic and one or more user are linked, and all these is realized on controller 7.
The first, the setter of sensor can make themselves or another one user become the owner of this sensor, has special right to calibrate, read wherein data, control its state, it is configured or deletes.These authorities can be distributed to a people individually, uniquely, or with the mode of any mixing and displacement jointly or commonage distribute to them.This can when installing first, finish or after changed because experiment finishes to mean that equipment is more usefully redistributed or is an authority that new individuality is given access control apparatus.
The example that provides from above by a people, may be D as can be seen, and the management common equipment is favourable.But E can be trained to calibrate some equipment rightly and preferably to be given the calibration authority of some or all equipment.A may wish to share the log record data with B, but is not real-time current data, and only is the data of log record.Control system makes these authorities and function can only be endowed correct people by being the devices allocation authority such as the software of password or some other types or the common authentication device of hardware keys.
For each equipment, if calibration and maintenance plan are the information that is associated with each equipment, then calibration and maintenance plan are best.This information can manually be imported when increasing equipment, perhaps can automatically import the configuration data from the producer.This system can carry out too early or in slow excessively warning regulator (for example E) in this calibration.If equipment is maintained according to appropriate calibration plan, user (A, B and C) can also be alerted, and makes them know that their data or control application may be affected.
Is favourable based on individual equipment for the user distributes authority, be convenient and useful perhaps based on equipment (for example all devices in the tank 1) related environment distribution or administration authority, it may be favourable perhaps finishing this work by such device type (for example, all oxygen probe).Preferably, equipment and/or set of circumstances are incorporated into project or experiment and distribute authority rightly.Correspondingly, generate the stratification sign, and the authority that changes the environment configurations parameter can be assigned to relevant device 6 that this project comprises or configuration information distributed to the independently individual who is connected with the stratification sign by controller 7.
The configuration data of equipment can comprise the position of environment, or equipment, picture are represented, the dependence of calibration parameter, control sequence, triggering thresholding and other equipment.User's suggestion is related with equipment and environmental facies.The performance of user's suggestion for a change historical record and with this experimental record of mode mark of laboratory record.That is, in case the input record, in order to defer to the requirement of science audit, they can not be deleted.Record be considered to import they, empirical tests the operator write down, and can be affixed to equipment and environment.Record can be read and retrieve by user, equipment and environment as any data that are logged.
When the user used controller, described picture represented it can is that icon, picture or the figure of equipment is maybe with the environment that is shown.Can import by the application of adopting process control system 1 or extract these pictures and represent.
The another one characteristic is that different pictures can license to and a plurality of users that equipment had authority.Further, the icon of equipment, picture or figure can change with the indication environment or equipment are had the authority of mandate.Similarly, the color of icon, picture or figure or shape can change according to the state or the triggering thresholding of equipment.
It can also be seen that such mode is useful, promptly different user has the different pictures of related distinct device, can also provide different parameters based on each user.For example, consider the situation that the air temperature sensor per second is all sampled to air themperature.A may need reading of data of per second in its experiment, and B may need per minute to read, and C needed read in per 30 seconds.A may be concerned about whether temperature (triggering thresholding) arrives 10 degrees centigrade, and B may be concerned about whether arrive 15 degrees centigrade.Such common parameter can store in the equipment, and based on each user demand give the permission that it revises these parameters.
In case B finishes his research, he may wish to share on-the-spot (in real time) with other people or data in the data recording archives in the past.It is described that other people can comprise colleague or aquatic products businessman G.B can authorize the authority that G inserts B, it can be inserted and the data that directly from control system, write down in obtain historical data.This permission will stop G to revise or change data, equipment and environment, not allow him to check the data of testing of A or C.
Second application level can be realized by the experiment framework (experimental setups) between importing or derivation equipment, environment and user and system.For example, if good processing that is used for salmon of B exploitation can directly export to this control architecture (control setups) the aquatic products businessman (G) who has similar control system and wish to culture salmon.Here, G is allowed to directly obtain environment and equipment, perhaps intelligently this framework is implanted into his environment, and by replacing environment and this framework of device control.Similarly, the producer of equipment can provide data, so that miscellaneous part can be replaced at an easy rate, sensor and gearing can be increased up at an easy rate.
Such importing and derived data can be the forms of the computer documents of manual switch, or be sent out by the electronic communication device that is used for manual installation such as Email, or by particular protocol transmission and foundation automatically, this agreement is located between the controller to promote this service.For example, a kind of simple mode is exactly by the tcp/ip communication port.
For for derived data, show that by logical diagram the equipment and the relation between the environment that derive in the controlling schemes are favourable.Before importing control data, such logical diagram can be independently with observable, perhaps can be after importing, by observed as system controller software of its operation part usually.
At last, if equipment and environment are shared, when increasing, changing or deleting user, equipment and environment, need special consideration so between the user.If D prepares (and having the authority of doing like this) and removes public air temperature sensor, but depending on this information, A, B and C succeed in doing experiment, discount just appears in Shi Yan integrality so.For realizing target, several schemes can be used.The first, if an equipment will be removed by D or heavily be dispensed in the new environment, A, B and C can automatically be apprised of this change by Email or another communicator so.In another complexity level, A, B and C may not have the ownership of this equipment or change power, but the data that this equipment provided are important to their work.Before their experimental work is finished, they can have that system gives to removing the veto power of this equipment.
If new equipment is added in an environment or the system, and can be for using usually or limitedly, its service can offer the user so that the data or the control that are provided is provided for they so.This can carry out communication by Email or another kind of communication mode, and perhaps its service can be carried out advertisement in not with a tabulation in the equipment.
Further, if a people who has or use equipment is removed from system, just need be by system management.In described first kind of situation, entitlement and authority can be added in existing obligee's list or distribute to a new person.Further, if equipment is not distributed based on removing of people, then they should be provided for assigned personnel in the same way, as the service of an aforesaid new equipment.
Can derive out similar purposes the multi-user of the commerce of a plurality of applications and research facilities.This method can be applied to the robotization and the control of the wide range of types except that above-mentioned aquatic products example at large and use.
Similarly, though example given here is an individual enterprise, the notion of shared device and service can be applied to stride any Control Network in a plurality of enterprises, position or the world.
