In addition, more than action can be thought the action of having deposited.
Then, in the native system, newly be provided with above-mentioned redundant manipulator 10, appended the illustrated action relevant with redundant manipulator 10.That is, redundant manipulator 10 is for example termly to each channel controller 3(3a, 3b, 3c) send illustrated status enquiry 2 by order wire 6.Received the channel controller 3 of this status enquiry 2, redundant manipulator 10 has been returned the answer Q of regulation.
, reply among the Q herein, comprise the status information of this channel controller 3, comprise the status information (normal/abnormal etc.) of the refrigerated medium pump unit 2 of these channel controller 3 management in this status information.Wherein, can also comprise such as the content of above-mentioned running instruction and the current state of each the partial air conditioning machine 1 under the management etc. among the answer Q.
In addition, redundant manipulator 10 monitors each machine communication line 5a, 5b, 5c at any time, on detection machine order wire 5a, 5b, the 5c no signal is arranged.In that to send and receive above-mentioned running shown in Figure 3 indication, response (normal/abnormal: OK/NG etc.), status enquiry 2, when replying Q etc., detect as signal is arranged.Wherein, do not understand the content of these data that send and receive.
In addition, status enquiry 2 and sending and receiving termly of Q of answer are carried out, thereby do not have the state of signal on above (for example more than 5 seconds) the machine communication line 5 of certain hour, are impossible in channel controller 3 normal situations at least.Therefore, redundant manipulator 10 does not have at machine communication line 5 in the situation of (for example more than 5 seconds) more than the state continuance certain hour of signal, and being judged to be does not have signal.
Then, the process chart of the redundant manipulator 10 of Fig. 4 described.
Among Fig. 4, redundant manipulator 10 is carried out the standby running control (step S1) of refrigerated medium pump unit 11 usually the time at first at any time.In addition, although not shown, monitor at any time above-mentioned machine communication line 5a, 5b, 5c, storage monitors result's (no signal is arranged).For example, as mentioned above, if do not detect signal more than the stipulated time, then judge, store " no signal ", if detect signal, then judge, store " signal is arranged ".
Then, carry out termly the transmission (step S2) to the above-mentioned status enquiry 2 of each channel controller 3, determine whether normal (OK) (the step S3) of communication.Have for status enquiry 2 and be judged to be normal (OK) (step S3 is) of communication in the situation of above-mentioned answer Q and transfer to step S4.On the other hand, in the situation that does not have above-mentioned answer Q, be judged to be communication abnormality (NG) (step S3, no) and transfer to step S6.
Among the step S4, state (status) information of the above-mentioned refrigerated medium pump unit 2 that comprises among the reference reversion Q (normal/abnormal etc.), if " normally " (step S4, no) then returns step S1, if the then processing of execution in step S5 of " unusually " (step S4 is).
Among the step S5, the channel controller 3 of the transmission source of this pump state answer Q that is " unusually " is sent " halt instruction ", then carry out redundant hand-off process (step S5).This redundancy hand-off process is described below, is to carry out the processing that substitutes running with above-mentioned redundant structure.In addition, received the channel controller 3 of above-mentioned " halt instruction ", stopped all controls and process.Thereby, stop with self management under general service pump 2 and the communicating by letter of local air conditioner 1, also stop and the communicating by letter of upper control device 4.
On the other hand, (step S3 in the situation that is judged to be above-mentioned communication abnormality (NG), no), with reference to the supervision result on the above-mentioned machine communication line 5 relevant with the channel controller 3 that becomes this communication abnormality (NG), in the situation of " signal is arranged ", be considered as monitoring normal (OK) (step S6 is) and execution in step S9.On the other hand, in the situation of " no signal ", be considered as monitoring unusual (NG) (step S6, no) and execution in step S7, S8.
In addition, such as because the fault of partial air conditioning machine 1 etc. although there is status enquiry 1 not reply in the situation of P, have detected the signal of status enquiry 1, be " signal is arranged " therefore.On the other hand, in the unusual situation of channel controller 3, even partial air conditioning machine 1 is normal, there is not status enquiry 1 yet, thus P do not replied yet, so be " no signal ".In addition, be judged to be in the unusual situation of channel controller 3, basically its refrigerated medium pump unit 2 stops automatically when channel controller 3 fault, though in addition simultaneously refrigerated medium pump unit 2 also fault also can't learn, therefore can not adopt redundant manipulator to inherit the method for the control of refrigerated medium pump unit 2.
Among the step S9, for example will notify the alarm of " order wire broken string ", send to for example upper control device 4.Then, return step S1.That is, in this situation, do not carry out the redundant hand-off process such as step S5 and S8, only carry out alarm.Then, continue the processing of Fig. 4.On the other hand, carry out in the situation such as the redundant hand-off process of step S5 and S8, do not carry out afterwards the processing (substituting running processes) of Fig. 4.
Among the step S7, for example will notify the alarm of " channel controller 3 abnormals ", send to for example upper control device 4.
Among the step S8, for the cooling system that is judged to be abnormal, carry out the redundant hand-off process same with above-mentioned steps S5.Wherein, step S5 sends " halt instruction " to channel controller 3 from different being of step S8 among the step S5 as mentioned above, but unusual because of existing in the channel controller 3 among the step S8, so even it is also nonsensical to send " halt instruction ", so do not carry out the transmission this point of " halt instruction ".
About above-mentioned redundant hand-off process, describe following.
In any one situation among above-mentioned steps S5, the step S8, redundant hand-off process is for example carried out following processing.
And then redundant manipulator 10 replaces existing the channel controller 3 of unusual cooling system to receive the new setting from upper control device 4, the instruction of turning round, and based on this new setting, running instruction, there is each partial air conditioning machine 1 of unusual cooling system in control.In addition, for this reason, redundant manipulator 10 for example will be arbitrarily general service pump 2 in the cooling system or the unusual generation of channel controller 3, by order wire 6 notices to upper control device 4.Thus, upper control device 4 will be set, the target of delivering letters of the instruction of turning round, and change to redundant manipulator 10 from the channel controller 3 that has unusual cooling system.
More than, the concrete example of above-mentioned redundant hand-off process has been described, but has been not limited to this concrete example.
Like this, replace existing the channel controller 3 of unusual cooling system and the management control that general service pump 2 is carried out each the partial air conditioning machine 1 that has unusual cooling system (cold-producing medium is supplied with, action indication, status data collect) (substituting running) with redundant structure (redundant manipulator 10 and treat pump 11).
By redundant structure (redundant manipulator 10 and treat pump 11) is set, not only can deal with the unusual of (correspondence) general service pump 2, also can deal with the unusual of (correspondence) channel controller 3.Then, by substituting accordingly running with unusual generation, cold-producing medium is supplied with can not stop but being continued.Thus, can make the temperature of local unit air conditioning area keep normal, can not cool off deficiency, thereby can prevent the fault of the information processor etc. in the zone and the state of affairs that data disappear.
In addition, can differentiate the unusual or simple communication abnormality of the unusual or channel controller 3 that unusually is general service pump 2, can carry out and differentiate the corresponding suitable alignment processing of result.
About with the corresponding system acting of above-mentioned processing, describe referring to Fig. 1, Fig. 5, Fig. 6.
At first, with reference to Fig. 1 system architecture has been described, referring to Fig. 1 system acting when normal has been described.In addition, illustrate that with reference to Fig. 5 there is the system acting in the unusual situation in refrigerated medium pump unit 2 afterwards, illustrate that with reference to Fig. 6 there is the system acting in the unusual situation in channel controller 3.
Wherein, below not one by one narration in the explanation, as previously discussed, communication between communication between the channel controller 3-upper control device 4, the redundant manipulator 10-upper control device 4, the communication between the redundant manipulator 10-channel controller 3 are by illustrated order wire 6(Ethernet(registration mark) etc.) carry out.In addition, communicate by letter (control and the Data Collection) of channel controller 3 and each partial air conditioning machine 1 is by illustrated machine communication line 5(5a, 5b, 5c; RS485 etc.) carry out.
In addition, below (2), (2) ', (3), (4), (4) ' in the explanation are the marks that represents on the figure of Fig. 1, Fig. 5, Fig. 6, put down in writing in order to be easy to explanation.
(A) in all regional areas, channel controller 3 and refrigerated medium pump unit 2 both sides run well and do not have in the situation of communication abnormality (with reference to Fig. 1):
(a) each channel controller 3 receives setting, the running instruction (2) from upper control device 4, the control (4) (above-mentioned running indication etc.) of each the partial air conditioning machine 1 under managing.In addition, control self-pumping (=general service pump 2) makes it to each the partial air conditioning machine 1 the supply system cryogen under managing.In addition, each channel controller 3 carries out the supervision that unusually waits with (4) such as operating conditions (above-mentioned status enquiry 1 and answer P) of each the partial air conditioning machine 1 under the fixed cycle collection management.In addition, each channel controller 3 checks the state (normal/abnormal) of self-pumping (=general service pump 2) at any time, the storage check result.
(b) each partial air conditioning machine 1 receives setting from channel controller 3, running indication (air quantity, blow out temperature, turn round, stop) (4), carries out air quantity control and blows out temperature (refrigerant valve) control, carries out the partial air conditioning running of regional area.
(c) redundant manipulator 10 is communicated by letter (3) with each channel controller 3a～3c termly, obtains, stores the state of a control data (above-mentioned status enquiry 2 and answer Q) of the channel controllers 3 such as state (normal/abnormal) of operating condition, its self-pumping (=general service pump 2) of each lower partial air conditioning machine 1 of setting, running command content, management that each channel controller 3 receives from upper control device 4.
In addition, redundant manipulator 10 is collected the communication (4) of the operating condition of each partial air conditioning machine 1 by monitoring (4) in the fixed cycle that is used for that each channel controller 3 is carried out ' monitor in, self-pumping (=treat pump 11) standby is turned round.
This for example the above is the example of normal condition, so in the processing of Fig. 4, repeatedly among execution in step S1 → step S2 → step S3 be → no among the step S4.
Wherein, (a) middle running indication is upper control device 4 → channel controller 3(2), but also can be upper control device 4 → channel controller 3(2) and redundant manipulator 10(2) '.
(B) switch because of general service pump unusual (take the fault of general service pump 2a as example; With reference to Fig. 5):
In this example, channel controller 3a detects cold-producing medium horizontal abnormality and the INV(inverter of self-pumping (=general service pump 2a)) unusually wait that (thus, channel controller 3a for example makes general service pump 2a shut down and makes alarm ON unusually.In addition, the abnormality detection information that comprises general service pump 2a among the above-mentioned answer Q).
In this routine situation, redundant manipulator 10 by with channel controller 3a communicate by letter (3) (above-mentioned status enquiry 2 and reply Q), unusual (judgement that among the above-mentioned steps S4 is) of the general service pump 2a of identification channel controller 3a.
Identify unusual redundant manipulator 10, carried out the processing of above-mentioned steps S5.That is, at first, channel controller 3a sent stop indication (3), make it stop running indication/state collection and treatment (4) to local air conditioner 1.And then, carry out the open and close valve switching controls (stopping to supply with from the cold-producing medium of the unusual pump 2a of channel controller 3a) of refrigerant piping, so that each partial air conditioning machine 1 of localized region A is from treating pump 11 the supply system cryogens.
That is, among Fig. 2, open and close valve 25a and open and close valve 26a are switched to " closing " state, and open and close valve 27a and open and close valve 28a are switched to "On" state.Thus, from treating that pump 11 is by redundant cold-producing medium each partial air conditioning machine 1 the supply system cryogen toward a part of localized region A of road pipe 23 and the past road of cold-producing medium pipe 21a.Equally, to the cold-producing medium after each partial air conditioning machine 1 supply of above-mentioned regional area A, the part and the redundant cold-producing medium that return road pipe 22a by cold-producing medium return road pipe 24, return and treat pump 11.
More than, by switch to the alternative running of using the redundant structure for regional area A, the structure of control from the utilize Fig. 5 dotted line of downside relevant with regional area A switches to the structure of utilizing the dotted line of upside among the figure and carries out.
Like this, even general service pump 2a abnormal also can make the temperature of local unit air conditioning area A keep normal.Certainly, this is not limited to general service pump 2a, in the situation of other general service pumps 2b, 2c fault too.
(C) switch because of channel controller 3 self unusual (take channel controller 3b unusually as example; With reference to Fig. 6):
Identified the unusual redundant manipulator 10 of channel controller 3b, carry out the open and close valve switching controls (stopping the general service pump 2b the supply system cryogen from channel controller 3b) of refrigerant piping, so that each partial air conditioning machine 1 of localized region B is from treating pump 11 the supply system cryogens.
That is, among Fig. 2, open and close valve 25b and open and close valve 26b are switched to " closing " state, and open and close valve 27b and open and close valve 28b are switched to "On" state.Thus, from treating that pump 11 is by redundant cold-producing medium each partial air conditioning machine 1 the supply system cryogen toward a part of localized region B of road pipe 23 and the past road of cold-producing medium pipe 21b.Equally, to the cold-producing medium after each partial air conditioning machine 1 supply of above-mentioned regional area B, the part and the redundant cold-producing medium that return road pipe 22b by cold-producing medium return road pipe 24, return and treat pump 11.
The setting from upper control device 4 after the switching, running instruction replace channel controller 3b to receive (2) by redundant manipulator 10 '.Then, with this running instruction etc. correspondingly each partial air conditioning machine 1 of localized region B send the running indication.
More than, by switch to the alternative running of using the redundant structure for regional area B, the structure of control from the utilize Fig. 6 dotted line of downside relevant with regional area B switches to the structure of utilizing the dotted line of upside among the figure and carries out.
Like this, even channel controller 3b abnormal also can make the temperature of local unit air conditioning area B keep normal.Certainly, occured in the unusual situation too at other channel controllers 3a, 3c.
(D) the Ethernet(registration mark between redundant manipulator 10 and the channel controller 3) communication abnormality is (take the communication abnormality relevant with channel controller 3c as example; Not shown):
In this example, not special diagram, but such as the above-mentioned mark of usefulness (2)～(4) such as reference Fig. 1 ' describe.
As illustrating among Fig. 4, in such situation, do not carry out the running of redundant structure (controller 10 and treat pump 11) is switched.Thus, channel controller 3c and its general service pump 2c work on.
But such state lower channel controller 3c can not receive new setting/running indication from upper control device 4, can not send data (status data of each the partial air conditioning machine 1 under the management etc.) to upper control device 4 from channel controller 3c.Thus, keep this state operation and inappropriate.Therefore, need to such as give the alarm as described in the above-mentioned step S9 (give the alarm etc. such as using level controller 4 or redundant manipulator 10), make such as operating personnel and wait the correspondence of carrying out the communication abnormality on the order wire 6.
In addition, in this situation, redundant manipulator 10 and treat that pump 11 does not substitute running for local control C, after the processing of above-mentioned steps S9, return step S1, continue the processing of Fig. 4, therefore in channel controller 3a and 3b or general service pump 2a and 2b, occured to substitute running in the unusual situation after.
And then, because high reliability can realize the two-fold of communication line, switch to when unusual and treat that machine circuit continues to process detecting circuit.
Structure, the FBD of expression redundant manipulator among Fig. 7.
Among Fig. 7, redundant manipulator 10 has the arithmetic processors 103 such as communication interface 101, memory 102, CPU/MPU, input/output interface 104 etc.
Communication interface 101 is to be connected with above-mentioned order wire 6, is used for the communication module that communicates by order wire 6 and each channel controller 3 and upper control device 4.In addition, communication interface 101 also has the structure that is connected with machine communication line 5, can detect having or not at the signal of machine communication line 5 circulation.
Input/output interface 104 is to be connected with treating pump 11, is the structure for the treatment of the signal of pump 11 usefulness for input and output control.
By being kept in the memory 102 with the data that communicating by letter of upper control device 4 obtains with above-mentioned each channel controller 3.In addition, in memory 102 pre-save the application program of regulation, arithmetic processor 103 is by reading, carry out this application program, realizes thus the processing of illustrated various processing capacity section.
That is, arithmetic processor 103 possesses monitoring unit 111, condition discrimination section 112, abnormality juding section 113, redundant switching part 114.
Monitoring unit 111 monitors that channel controllers 3 communicate by letter with each partial air conditioning machine 1 having or not of signal on the above-mentioned machine communication line 5 of usefulness.Then, will monitor that result's (having or not of signal) is kept in the memory 102.
Condition discrimination section 112 communicates by order wire 6 and each channel controller 3, and can judgement communicate by letter, and obtains at least the normal/abnormal state of general service pump 2 in situation about can communicate by letter.As mentioned above, reply the normal/abnormal status data that comprises general service pump 2 among the Q, so just can obtain the normal/abnormal state of general service pump 2 so long as not communicating by letter.
Can abnormality juding section 113 carry out the abnormality juding of general service pump 2, channel controller 3 based on the normal/abnormal state of the general service pump 2 in the situation that has or not, communicate by letter, can communicate by letter with channel controller 3 of the signal on the machine communication line 5.Special judge to be normal or simple communication abnormality or general service pump 2 are unusual or channel controller 3 is unusual.
This judges as mentioned above, the normal/abnormal status data of the general service pump 2 of obtaining by can communicate by letter with channel controller 3 time, and it is normal or unusual to identify general service pump 2.In addition, in situation that channel controller 3 can not be communicated by letter, if do not have signal on the machine communication line 5 then to be judged to be channel controller 3 unusual, if on the machine communication line 5 signal is arranged then be judged to be simple communication abnormality (order wire 6 broken strings etc.).In addition situation is judged to be normally.
Redundant switching part 114 is utilizing above-mentioned abnormality juding section 113 to be judged to be in the unusual situation of the unusual or channel controller of general service pump 23, carries out with treating that pump 11 replaces 2 pairs of general service pumps to have many partial air conditioning machines 1 the supply system cryogen of unusual cooling system and replaces channel controllers 3 management to control above-mentioned many partial air conditioning machines and treat the hand-off process of pump 11 with redundant manipulator 10.
This hand-off process is the switching hand-off process of above-mentioned open and close valve etc.In addition, in the unusual situation of general service pump 2, also comprise and send above-mentioned halt instruction etc.
Wherein, channel controller 3 also is the structure roughly the same with above-mentioned Fig. 7 on hardware.But the linking objective of input/output interface 104 is general service pumps 2, and the application program of preserving in memory 102 is different from redundant manipulator 10.Thereby, read, carry out in memory 102 the various processing capacities that the application program of preserving realizes by arithmetic processor 103, different from the processing capacity of above-mentioned symbol 111～114.But, in the situation of channel controller 3, nearly all be the processing capacity of having deposited, just increased the processing that generates, sends above-mentioned answer Q for above-mentioned status enquiry 2, so do not illustrate especially, illustrate herein.Also roughly same for upper control device 4, do not illustrate especially herein, illustrate.
As described above, in this method, at first as the redundant structure, not the pump that the preparation of redundant usefulness only is set such as prior art, but " redundant manipulator 10+ treats pump 11 " is set.Then, redundant manipulator 10 not only monitors the unusual of general service pump 2 in standby, also monitors the unusual of channel controller 3.
Monitor upper (higher level) and each communications status of the next (subordinate) of channel controller 3, unusual situation in judge all that higher level and the both sides of subordinate channel controller 3 self is unusual, switch to the alternative running of using redundant structure (redundant manipulator 10+ treats pump 11).
Wherein, the communication of " higher level " refers to communicating by letter by order wire 6 and each channel controller 3.
In addition, correspondence is carried out the processing of Fig. 4, redundant manipulator 10 communicates by the order wire different from machine communication line 56 and each channel controller 3, can judgement communicate by letter, the obtaining of state (normal/abnormal) of carrying out general service pump 2 in the situation about can communicate by letter gets final product, and not necessarily needs upper control device 4 on this meaning.In the absence of upper control device 4, certainly do not have above-mentioned and communication process upper control device 4, each channel controller 3 for example draw oneself up by oneself the management under partial air conditioning machine 1 and general service pump 2, but the processing of redundant manipulator 10 usefulness step S2, not only can obtain the state of general service pump 2, can also obtain current Control the content, therefore when abnormal, can former state inherit control.
In addition, whether common channel controller 3 operating condition of collecting each partial air conditioning machine 1 of the next (subordinate) with the fixed cycle is interrupted and is become without the state of communicating by letter and monitor for the communication of this collections usefulness.
In the local air conditioning system in IDC, outside " channel controller+general service pump " of common structure " redundant manipulator+treat pump " of configuring redundancy structure, redundant side monitors the operating condition of side commonly used.At this moment, not only monitor general service pump, also monitor the unusual of channel controller self, if exist unusually then switch to the redundant structure, respective pump unusual not only thus, also corresponding controller is unusual, switches to the redundant structure when unusual detecting, and can make reliably thus the temperature of local unit air conditioning area keep normal.
Computer room air-conditioning system of the present invention, by its redundant manipulator etc., not only corresponding refrigerated medium pump is unusual, also corresponding controller is unusual, cold-producing medium is supplied with do not stop but being continued, can make the temperature of regional area keep normal, can not cool off deficiency, thereby can prevent the fault of information processor etc. and the state of affairs that data disappear.
