Control device 20 possesses data input part 21.The sensing data detected by sensor being configured at turbine 11 is fed into data input part 21.Such as the expression rotation number of turbine 11, the sensing data of rotational speed are fed into data input part 21.Being supplied to the sensing data of this data input part 21, is that every some cycles samples the signal that sensor exports and the numerical data obtained.Such as, when representing the data of rotational speed of turbine 11, such as often count m second, sensing data is fed into data input part 21.
The sensing data being supplied to data input part 21 is fed into timestamp addition portion 22.In timestamp addition portion 22, timestamp is added to each sensing data that every some cycles is supplied to.Timestamp is the data of figure place of regulation, is once represented the time series of data by the data of every 1 unit, value increase.In addition, timestamp also can be the data representing the absolute moment such as hour, minute, second.
Further, the sensing data that with the addition of timestamp in timestamp addition portion 22 is fed into data processing division 23.The value of data processing division 23 pairs of sensing datas judges, when certain conditions are met, is set as sending data.
At this, according to the control of control part 24, the example of certain condition that data processing division 23 judges is described.In order to carry out this judgement, for each of each sensing data, pre-determining threshold value, and being recorded in data processing division 23.Then, data processing division 23 obtains the sensing data and the difference of the sensing data that have input thereafter that have sent last time, judges whether the absolute value of this difference exceedes threshold value.In this judgement, when difference exceedes threshold value, corresponding sensing data is set as send data.That is, following judgement is carried out.

In addition, it is examples that the every some cycles of network communication unit 25 sends primary transducer data, also can be whenever sending when data processing division 23 sets and sends data.
In addition, the steering order transmitted from monitoring arrangement 40 is received by network communication unit 25, and the content of this steering order received is identified by the control part 24 being connected to data processing division 23.Control part 24, according to the steering order of this identification, generates the instruction of the action of instruction turbine 11 in command generation unit 26.The instruction of the action of the instruction turbine 11 generated in command generation unit 26, is fed into each several part of turbine 11, controls the action of turbine 11 according to this instruction from data output section 27.
[structure of monitoring arrangement]
Fig. 3 is the figure of the structure example representing monitoring arrangement 40.
Monitoring arrangement 40 possesses network communication unit 41.Network communication unit 41 plays the function of the data reception portion receiving the data sent from control device 20,30 (Fig. 1), and plays the function of the data sending part sending data from network communication unit 41 to control device 20,30.
The data received by network communication unit 41 are fed into data processing division 42, and each kind for the data received under the control of control part 43 processes.Such as, when network communication unit 41 receives the sensing data transmitted from control device 20, this sensing data is stored in the storage part 44 being connected to data processing division 42.Now, at data processing division 42, according to the timestamp adding sensing data to, judge the time point detecting the value represented by sensing data, make sensing data be that the correct data arranged are stored in storage part 44.
Then, data processing division 42 is according to the control of control part 43, and the data that data network communication unit 41 received, storage part 44 store are supplied to Graphics Processing portion 45.In Graphics Processing portion 45, use the data be supplied to from data processing division 42, make the display data of the monitoring image of generating plant 10, the display data that this is made into are fed into display 46.At display 46, show the monitoring image formed by display data.
At this, when the trend map that display 46 shows each several part of generating plant 10 is as monitoring image, the sensing data being stored in storage part 44 is read by data processing division 42, carries out display graphics make process at data processing division 42.That is, data processing division 42 plays the function that display graphics makes handling part.Then, the data of the trend map processed by data processing division 42 are sent to Graphics Processing portion 45, and Graphics Processing portion 45 makes the display data of trend map.Then, the display data of the trend map be made into by Graphics Processing portion 45 are fed into display 46, show trend map by display 46.In addition, the trend map be made into is stored in storage part 44.By the operation of supervisory work person, the trend map being stored in this storage part 44 can be made to be presented at display 46 at any time.In addition, be stored in the trend map of storage part 44, as required the data of trend map can be forwarded to external mechanical from monitoring arrangement 40.
[action of control device]
Fig. 4 represents that sensing data is sent to the process flow diagram of the process of monitoring arrangement 40 by control device 20.Send the process of this sensing data, performed by the control of control part 24.
First, control part 24 judges whether to have input sensing data (step S11) to data input part 21.At this, when being judged as non-input pickup data, control part 24 is standby, until sensing data is input to data input part 21.
Then, when being judged as in step s 11 have input sensing data, by the control of control part 24, timestamp addition portion 22 pairs of sensing datas add timestamp (step S12).
The sensing data that with the addition of timestamp is sent to data processing division 23, carries out the determination processing for sending at data processing division 23.At this, data processing division 23 judges whether the sensing data be supplied to is the data of initial input or the data (step S13) in the time point input that have passed through 1 second from the transmission of last time.At this, when the sensing data be supplied to is the data of initial input and when the sensing data be supplied to is the data of the time point input that have passed through 1 second from the transmission of last time, the sensing data now inputted is set as sending data (step S15) by data processing division 23.
In addition, in step s 13, the sensing data be supplied to be not the data of initial input and be the data without the time point input of 1 second from the transmission of last time when, data processing division 23 transfers to the judgement of step S14.In step S14, data processing division 23 calculates the difference of the value of the value represented by the sensing data inputted and the data sent last time, judges whether the value of this difference exceedes predetermined threshold value.Then, in the judgement of step S14, when being judged as that the value of difference exceedes the threshold value be previously determined, transfer to the process of step S15, the sensing data now inputted is set as sending data by data processing division 23.
Then, in the judgement of step S14, when being judged as that the value of difference is below the threshold value be previously determined, the sensing data now inputted can not be set to send data, and data processing division 23 turns back to the judgement of step S11.In addition, after the sensing data of input being set as sending data in step S15, data processing division 23 also turns back to the judgement of step S11.
Whether thus, at data processing division 23, whenever input pickup data, carrying out sensing data is the judgement process sending data.Then, in network communication unit 25, the sensing data being set to send data in step S15 is sent out under the state that with the addition of timestamp.The transmission data of this setting, such as, every the some cycles of 1 second etc., batch sends once from network communication unit 25.
[data send the example of state]
Fig. 5 is the figure of the example of the transmission state of the sensing data represented at control device 20.Fig. 5 A is the example of the little situation of the change of sensing data, and Fig. 5 B is the example of the situation that the change of sensing data is large.
In the example shown in Fig. 5 A, Fig. 5 B, sensing data is supplied to control device 20 from turbine 11 with the short period (in this case 10m cycle second).Such as shown in Figure 5A, supply sensing data D0 at time point t0, the time point t1 after 10m second supplies sensing data D1, and after this, every 10m supplies sensing data second.Now, at control device 20, to each sensing data D0, D1, D2 ... give the timestamp of successive value.
If the transmission state of sensing data is described, then the sensing data D0 of the time point t0 of initial input is set to send data, is sent to monitoring arrangement 40.Then, in a situation of fig. 5 a, each sensing data D1 supplied after this sensing data D0, D2 ..., in the judgement in the step S14 of the process flow diagram of Fig. 4, be all judged as with the difference of sensing data D0 below threshold value.Now, do not carry out the transmission of sensing data, until through certain hour (1 second).
Then, the sensing data D100 that the time point t100 that have passed through 1 second the transmission from sensing data D0 have input is set to send data, is sent to monitoring arrangement 40.
Like this, under the state not exceeding the change of threshold value at sensing data, every 1 second transmission primary transducer data.
On the other hand, in the example of Fig. 5 B, after the sensing data D0 of the time point t0 that have input at first has been sent to monitoring arrangement 40, the variable quantity of the sensing data D1 of future time point t1 has exceeded threshold value.Now, after the transmission of the sensing data D0 of time point t0, then carry out the transmission of the sensing data D1 of time point t1.After this, because the change exceeding threshold value occurs in succession, thus carry out the transmission of the sensing data D2 of time point t2, the sensing data D3 of time point t3 transmission ... the transmission of the sensing data of every 10m second like this.Wherein, the every some cycles batch of the transmission of these sensing datas carries out once.And, and the variable quantity between the sensing data sent before becomes below threshold value, then can be changing into the sensing data in the 1 second cycle only sent as shown in Figure 5A.
Like this, when sensing data existence exceedes the change of threshold value, the sensing data being input to control device 20 can be sent to monitoring arrangement 40 respectively.
[action of monitoring arrangement]
Fig. 6 represents that monitoring arrangement 40 shows the process flow diagram of the process of trend map.Show the process of this trend map, performed by the control of control part 43.
First, control part 43 judges whether have received sensing data (step S21) in network communication unit 41.At this, when being judged as non-receiving sensor data, control part 43 is standby, until receive sensing data.
Then, when being judged as in the step s 21 have received sensing data, control part 43 passes through data processing division 42, according to the timestamp being added on the sensing data received, suitably regulation time axle, makes sensing data mark and draw on figure (step S22).Then, control part 43 according to the trend map marked and drawed in step S22, the display Data Update (step S23) that Graphics Processing portion 45 is made.
Carried out showing the renewal of data in step S23 after, control part 43 has turned back to the judgement of step S21.
[example of trend map]
Fig. 7 is the figure of the example of the trend map shown by display 46 representing monitoring arrangement 40.
In the trend map of this Fig. 7, the longitudinal axis represents the rotational speed of turbine 11, horizontal axis representing time (second (s in accompanying drawing)).Under the state that the change of rotational speed is smaller, the figure formed by the sensing data of every 1 second transmission primaries is shown, and change large during x and period y, become by the figure formed with the sensing data of the periodic transfer shorter than 1 second.In this example, each value marked and drawed on figure illustrates with the state be connected to by line L.
In addition, when making trend map as shown in Figure 7, according to the timestamp being added on each sensing data, rotational speed values is plotted in the tram on time shaft (transverse axis).
In addition, connect the line L of each plotting position, in the interval of the plotting data of every 1 second, with meaning that the value of last time lasts till that being about to the straight line marked and drawed before new value represents, before being about to mark and draw new value, curved shape ground change also represents in the stair-stepping mode being connected to new value.
By showing such trend map, monitoring the supervisory work person of monitoring arrangement 40, the trend of sensing data can judged according to trend map, and also can carry out the trend of the calculating process of the logic of the calculating of sensing data etc.That is, when monitored object equipment exist some abnormal time, details when can understand abnormal generation according to the display formed by the sensing data transmitted with the short period.In addition, also according to the sensing data transmitted with the short period, the trend of carrying out the calculating process of the logic of the calculating of this sensing data etc. can be judged.Further, when the operational situation of monitored object equipment is in stable state, according to by the display formed with the sensing data of MIN periodic transfer, known its is in stable state.In addition, the trend map that can store according to the storage part 44 of monitoring arrangement 40, carries out the detailed anomaly analysis of generating plant, abnormal omen analysis.Therefore, according to the supervisor control of this example, good supervision can be carried out.
Then, on the network 90 of connection control device 20,30 and monitoring arrangement 40, send once in bulk, so can prevent in network 90 with short period transmission sensor data at the every some cycles of sensing data of control device 20,30 side setting.Therefore, it is possible to reduce the volume of transmitted data of network 90, thus effectively can cut down the load of network 90, the delay of the transmission data caused greatly due to offered load, gaps and omissions can be suppressed in Min..In the system shown in figure 1, illustrate only two control device 20,30, but in fact there is a large amount of control device to be connected to a network 90, in addition, the kind of the sensing data handled by a control device is also a large amount of, the traffic volume of each sensing data can be cut down, thus the traffic of overall network can be cut down significantly.
In addition, make in monitoring arrangement 40 in the process of trend map, the trend map that the interval of sensing data is short is only made when sensing data exists variation, as long as make the trend map that the interval of sensing data is long at steady-state, thus also can alleviate the process load in monitoring arrangement 40.
In addition, in the case of this example, as shown in Figure 7, marking and drawing the interval of every 1 second such cycle long sensing data, last till that being about to the straight line marked and drawed before new value represents, also can alleviate the load of monitoring arrangement 40 thus by the value of last time.That is, monitoring arrangement 40 is when making trend map, until receive the state change that each sensing data do not need to make trend map represent.Therefore, when monitoring arrangement 40 makes trend map, figure can be made with a small amount of processing operation, also can alleviate the load of monitoring arrangement 40 from this point of view.
In addition, for the stair-stepping line L shown in Fig. 7, in the process of monitoring arrangement 40, after have passed through the time to a certain degree, line L also can be formed as the level and smooth line connecting each plot point with straight line.
[modified example]
In addition, the embodiment example so far illustrated is the example of the supervisor control being applicable to generating plant.On the other hand, the present invention also goes for carrying out various factories in addition etc. and is controlled the supervision of object-based device, the supervisor control of control.
In addition, be used in the trend map illustrated in above-mentioned embodiment example and represent that the rotational speed this point of turbine is also an example, also can represent sensing data in addition with trend map.In addition, 1 second equivalence as the cycle of carrying out sensing data transmission also shows an example, as long as set the suitable cycle for the every kind of each data.
In addition, in above-mentioned embodiment example, judge whether that the threshold value being set as sending data is fixing value, but also can such as in the data sent last time, be multiplied by fixing coefficient and try to achieve threshold value.Thus, when sensing data is large value, set larger threshold value, when sensing data is little value, set smaller threshold value, thus the threshold value of the situation be suitable at that time can be set.
In addition, in above-mentioned embodiment example, the transmission every some cycles of sensing data from control device 20,30 to monitoring arrangement 40 carries out once, thus sending part sends the sensing data be set in bulk with some cycles.The cycle of this sensing data of Batch sending can adopt 1 second and wait the changeless cycle all the time, also can change according to situation.Such as, when the situation that the quantity of the sensing data being set as transmission data is many, it can be also 0.5 second cycle etc. by the periodic change of 1 second.Or, when there is the stipulated time continuously in the situation that the variation of sensing data is large, also can the Batch sending of temporary transient stop sensor data, will be set as that the sensing data sending data is successively sent to monitoring arrangement 40.In addition, also can be by the instruction from monitoring arrangement 40, the interval that each control device 20,30 carries out the cycle of Batch sending, the sensing data of variation hour transmission can be changed.Thus, monitoring arrangement 40 can carry out the suitable supervision corresponding with the situation of the factory as monitored object.
In addition, only sending of illustrating in above-mentioned embodiment example meets the process of the sensing data of certain condition, also optionally can carry out according to the situation of network etc.Such as, when monitoring arrangement 40 detects that the communication conditions of network is crowded, send instruction from monitoring arrangement 40 to control device 20,30, the control device 20,30 receiving this instruction carries out only by process that the sensing data meeting certain condition sends in bulk with some cycles.Then, under the situation that the communication conditions of network is not crowded, control device 20,30 also can send sensing data with the cycle shorter than above-mentioned some cycles.
Or, when monitoring arrangement 40 needs to carry out than usually more tight supervision specific supervision project, instruction is sent from monitoring arrangement 40 to control device 20 grade, for this specific monitored item object sensing data, even if difference is below threshold value, also the sensing data of all time points can be sent to monitoring arrangement 40.Thereby, it is possible to reply such as some adjustment is carried out to specific turbine after, the such situation of operational situation after its adjustment of wanting temporarily to look over one's shoulder.
In addition, supervisor control of the present invention also can be made up of program (software), this program is installed to the control device 20 of existing supervisor control, 30, monitoring arrangement 40, thus carry out the process that describes in above-mentioned embodiment example.In the case, program can be recorded in various recording medium such as such as semiconductor memory, CD etc., thus via this recording medium, be installed to control device 20,30, monitoring arrangement 40.
