Do explanation in further detail below in conjunction with the accompanying drawing specific embodiments of the invention.
Embodiment one, and referring to shown in Figure 1, the air-conditioning dual-host backup control method of present embodiment may further comprise the steps:
S1, set up communicating to connect between air-conditioner host and the random, and both are connected with control module respectively;
S2, control module are gathered the running state information of air-conditioner host and random in real time, are labeled as parameter S, and wherein, the value of parameter S comprises: all normally operation and an air conditioner normally move two air conditioners;
S3, according to the value of parameter S, carry out the Different control step.
In step S1, the communication of being set up is connected to 485 and connects.
Because running status is very important respectively at first to obtain two air conditioners; Running state of air conditioner is bigger to inside of base station temperature effect; In traditional scheme control; When two machines time of all just often carrying out switch no problem, but can cause base station temperature rising when when fault that can't freeze appears in certain air-conditioning, running into this operation of air conditioner again.Therefore to consider the current running status of different air-conditionings; The current state of two air conditioners that collect through communication according to control module judges that whether machine is in state in proper working order, confirms the operation of air conditioner mode through running status; For there being certain mechanical disorder situation; Need be controlled to be the first element this moment with satisfied temperature, and the air-conditioning state parameter is represented with S, and all normally operation and an air conditioner normally move two kinds of situations to be divided into two air conditioners.When having only an air conditioner normally to move, be main purpose with the control temperature, so can not switch this moment; Need normal machine running, the fault machine is shut down, when two air conditioners all normally move; Consider that two air-conditioning wheels change jobs, and guarantee that two air-conditioning groundwork times are identical.If have only an air conditioner normally to move, then need not to make self adaptation and regulate based on complex environment, therefore, comprise following substep among the step S3:
S31, if having only an air conditioner operate as normal, then control the air conditioner continuous service of this operate as normal;
S32, if two air conditioners operate as normal all then control two air conditioners wheels and change jobs.
As a concrete embodiment; When two equal operate as normal of air conditioner; Can face various complex environments on every side; Therefore need carry out the Different control method according to different environment, involved reaction environment complicated parameter comprises air-conditioning installation site, running state of air conditioner, inside of base station hot load state etc. in the present embodiment, and the relevant environment parameter value all can be divided judgement from the data of air-conditioning collection; Thereby judge the characteristics that characteristics in base station own and air-conditioning are installed, realize the different control operation methods that control environment then.Also comprise real-time collection thermic load parameter F and heat load distribution balance parameters X among the step S32, need to prove, wherein; To the inside of base station thermic load; The base station of two air-conditionings has been installed can monitor mutually and Coordination Treatment, and the cooling-down effect that detects during through two air-conditioning works is confirmed the relatively hot payload, and the thermic load parameter is represented with the F parameter; Possibly exist the phenomenon of different thermic loads according to different base station inside; For same base station, Various Seasonal and intraday different period, thermic load also is inequality simultaneously.Indoor temperature change generated in case when adopting through single machine work detects, and can judge indoor thermic load size, and the thermic load parameter F comprises indoor high load capacity type FH and indoor underload type FL.
Because of inner relevant device layout can have influence on whole inside of base station temperature field, the space layout of whole base station can have influence on the temperature field of whole base station equally, and the distribution of the thermic load of whole base station simultaneously also can have influence on the temperature field of inside of base station.Correspond to the inside of base station temperature field that an air-conditioning can't monitor; For the base station that two air-conditionings have been installed; Can judge the inside relative installation of two air-conditionings through the indoor environment temperature that two air-conditionings detect; Confirm associated inner ventilation effect, internal heat load distribution situation thus; Differentiate in carrying out the environment territory with ventilation effect according to heat load distribution, heat load distribution balance parameters X comprises that the mutual unobstructed balanced type X0J of two air conditioners, single air conditioner stop that unbalanced type X1J and two air conditioners stop unbalanced type X2J each other.
It also is different requiring the running status of two air-conditionings to require for different thermic loads; Satisfied not the high temperature problem that requires and cause for fear of an independent air-conditioning; When high load capacity, need consider to move simultaneously two air-conditionings, to guarantee whole base station decrease of temperature.To the method for operation of F parameter, the indoor temperature change generated in case that detects when working through single machine, as collect indoor temperature and surpassed the temperature that two-shipper moves simultaneously, this moment, air-conditioning out of service was also participated in operation.Concrete, the acquisition mode of thermic load parameter F is: during arbitrary work of two air conditioners, temperature change value T this air conditioner sensing chamber in is higher than threshold value T1 as if T, then is indoor high load capacity type FH, otherwise is indoor underload type FL.
The acquisition mode of heat load distribution balance parameters X is: during air conditioner A work, and temperature change value in the air conditioner B sensing chamber, greater than the detected indoor temperature change generated in case value of air conditioner A self, then air conditioner A is unobstructed to B as if the detected indoor temperature change generated in case value of air conditioner B; Otherwise stop that for having wherein, air conditioner A is air-conditioner host or random, corresponding; Air conditioner B is air-conditioning random or main frame, according to aforesaid way, detects when air-conditioner host, random are worked respectively; If testing result is mutual when unobstructed when two air conditioners, be X0J, when only existing a side to stop between two air conditioners; Be X1J, when two air conditioners stop each other, be X2J.
Among the step S32,, explain and only move the work that an air conditioner can't satisfy cooling in the base station, then control two air conditioners and move simultaneously if the thermic load parameter F is indoor high load capacity type FH; Otherwise, carry out different instructions according to two air conditioners of value control of heat load distribution balance parameters X.Need to prove; In running, control module is still gathered the thermic load parameter F in real time, in case when the indoor high load capacity type FH of execution operates accordingly; Satisfied the condition of indoor underload type FL; Perhaps when the indoor underload type FL of execution operates accordingly, satisfy the condition of indoor high load capacity type FH, then need change control strategy.
The front has been mentioned if the thermic load parameter F is indoor underload type FL; Then judge heat load distribution balance parameters X; If heat load distribution balance parameters X is X0J, also promptly two air conditioners are unobstructed each other, and the separate unit operation of air conditioner promptly can satisfy the operation of whole base station; This moment, no matter for which platform machine operation ventilating all to guarantee whole base station demand.In order to save the energy, consider that air-conditioning installs opposite position and control this moment.Because different air-conditioning installation sites, be installed in sunny side such as one, another one is installed in the back; Therefore, the outdoor temperature that two air-conditioners collect is different, and the difference P situation of the outdoor environment temperature that collects according to two air-conditioners is concluded; Season in the P parameter tracking, outdoor situations constantly changes; Possibly change repeatedly within one day, so the judgement of P parameter also follows environment and continue to judge, calculate as basis according to the outdoor temperature difference data that are consecutively detected.Different according to the P parameter; Judge the different machine of different time operation; The power consumption of striving for reaching two air-conditionings on the basis of two machine equilibrium operating times is minimum, and purpose just selects the mode of the high operation of air conditioner of Energy Efficiency Ratio to reduce the total run time of two air-conditionings according to ambient conditions.Concrete, the acquisition method of P is: two outdoor temperature difference △ T that air conditioner is consecutively detected, if △ T is greater than threshold value T2; Then be the outdoor temperature difference type PH of high difference; Otherwise, when outdoor temperature difference parameters P is PH, move the low air-conditioning of detected outdoor temperature for the low outdoor temperature difference type PL of difference; Otherwise, move the high air-conditioning of detected outdoor temperature.So both satisfy the time equalization of two machines, satisfied the energy-saving and cost-reducing of whole base station again.
If heat load distribution balance parameters X is X1J, promptly one of them air conditioner does not receive wind when an other air conditioner is worked, and this air conditioner is for being stopped machine; Another air conditioner is the non-machine that stopped, can be guaranteed the inside of base station temperature equalization machine when operation when non-stopping; Carry out corresponding operation during for X0J by parameter X, when being stopped the machine operation, descended slowly by the space temperature of barrier zones; Be slowly will be lowered fully by the temperature of barrier zones through indoor wind convection current; Thereby cause two results: one is that the house interior temperature is unbalanced, and the place that possibly lower the temperature temperature does not on the contrary lower, and another one result is stopped that because of the air-conditioning air-out causing air-conditioning to reach temperature requirement once working recovers the temperature of needs start once stopping temperature; Cause the air-conditioning frequent start-stop; For this type,, should take following measure to avoid: non-ly to be stopped temperature T 3 in the real-time sensing chamber of machine when avoiding above-mentioned phenomenon when being stopped air-conditioning work; If T3 is greater than threshold value T4, then starts and non-ly stopped that machine moves simultaneously;
If heat load distribution balance parameters X is X2J, promptly two air conditioners are and are stopped machine, and during one of them air conditioner work, temperature T 5 in the real-time sensing chamber of another one air conditioner is if T5 greater than threshold value T4, then starts two air conditioners and moves simultaneously.
Need to prove that equally in running, control module is still gathered heat load distribution balance parameters X in real time, in case variation has taken place parameter, then need change control strategy, the corresponding control step after execution parameter changes.
Embodiment two; Based on the air-conditioning dual-host backup control method among the embodiment one, the present invention provides a kind of air-conditioning dual-host backup to control system simultaneously, comprises air-conditioner host, air-conditioning random and control module; Also comprise the involved concrete steps that arrive among the embodiment one, do not do at this and give unnecessary details.
