The specific embodiment
Below, with reference to accompanying drawing, the effect of the embodiment of the invention is elaborated.
Fig. 2 is the central air conditioner system structural representation with black box of the present invention.
As shown in Figure 2, central air conditioner system of the present invention utilizing computer 4 by in the existing central air conditioner system of RS232C module 3 real-time demonstration information, has been set up black box 5.
Above-mentioned black box 5 is between the off-premises station 2 and RS232C module 3 of central air conditioner system, the various information of system (such as, the sensed values of the various sensors of central air conditioner system or exercises changing value) store in real time, and when making a mistake, interrupt storage operation.Therefore wrong time of origin point can be known, and the data of a period of time before the point of interruption can be stored.
That is, under the normal condition of central air conditioner system, by the various information of RS232C real-time Transmission and stocking system.And occur stopping storage operation when wrong.Thereby, can know wrong system information at that time to occur.
Afterwards, the data after the above-mentioned storage can be passed through RS232C module 3, are presented at computer 2.Therefore, can pass through these data, find failure cause, such as states such as wrong pressure, temperature, valve at that time be unusual occurring.
Here, consider the memory space of black box 5 inside, set certain program, after said system information is stored into to a certain degree, the data before deleting in order.Thereby, receiving system information successfully.
Fig. 3 is a central air-conditioning black box internal structure schematic diagram of the present invention.
As shown in Figure 3, black box 5 of the present invention is made up of switch 51, microprocessor 52, memory 53.The pattern of switch 51 decision black boxes 5.Microprocessor 52 is used for communication or control.Memory 53 is used to store the various information of the central air conditioner system that above-mentioned microprocessor 52 spreads out of.
Under normal condition, have the black box 5 of said structure,, the control of passing through microprocessor 52 from the data that off-premises station 2 receives, is passed to RS232C module 3, and is stored in memory 53 in real time.
Press the capacity of memory 53, when the data volume of above-mentioned storage acquires a certain degree, press the mode (FIFO:First In First Out) of FIFO, delete the data that stored in order.
If above-mentioned central air-conditioning produces mistake, then above-mentioned microprocessor 52 allows storage operation stop, and can preserve the system information that makes a mistake at that time.
In the operation afterwards of the information of above-mentioned storage, can be presented at computer 4 by RS232C module 3, the useful information as finding failure cause is carried out utilization.
Here, black box 5 internal switches 51 of the present invention are used as the parts that determine black box 5 mode of operations.Below, be explained with reference to Fig. 4.
