The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Fig. 1 is the schematic diagram according to the structure of the system of the monitoring air conditioner group of the embodiment of the invention.As shown in Figure 1, in the present embodiment, the system of monitoring air conditioner group comprises a plurality of communication modules 11, communication interface device 12 and calculation element 13.Wherein, each communication module 11 is connected with one or more air-conditioning unit 10, is used to obtain the data of air-conditioning unit 10 and to air-conditioning unit 10 sending controling instructions; Communication interface device 12 is connected with calculation element 13 and a plurality of communication module 11, is used for the data between transfer calculation element 13 and the communication module 11, for example can be the RS232/485 converter; Calculation element 13 is used to obtain and handle the data of air-conditioning unit 10 and sends according to this data generation control instruction and to communication module 11.Communication interface device 12 can also be used for the data between described calculation element of TCP/IP mode transfer and the described communication module.
A plurality of air-conditioning units 10 that each communication module 11 is connected can make up according to user's wish, wherein can comprise different types of machines.
System shown in Figure 1 can be used for the air-conditioning unit is monitored.Communication interface device 12 obtains the device data of the air-conditioning unit 10 that self connects, and this device data is sent to calculation element 13.This device data has comprised the operation information of air-conditioning unit 10.Calculation element 13 is preserved the operation information of air-conditioning unit 10 according to the device data of receiving, perhaps exports operation information, for example shows on man-machine interface.
Use system shown in Figure 1, adopt communication module and communication interface device to set up communicating to connect between air-conditioning unit and the calculation element, and can between calculation element and air-conditioning unit, transmit data according to RS232/485 agreement or ICP/IP protocol, realize remote monitoring thus the air-conditioning unit.When carrying out this remote monitoring, can adopt the method for the control air-conditioning unit that provides in the embodiment of the invention and monitor the method for air-conditioning unit, below to this with describing in detail.
Fig. 2 is the flow chart according to the method for the monitoring air conditioner group in the embodiment of the invention.According to flow process shown in Figure 2, can control the air-conditioning unit from long-range.As shown in Figure 2, the method for the monitoring air conditioner group in the embodiment of the invention mainly comprises the steps:
Step 21: receive configuration-direct.This configuration-direct is used for determining to carry out the air-conditioning unit of data communication.This configuration-direct is to import in the man-machine interface by the calculation element 13 of operating personnel in Fig. 1, this configuration-direct has been specified the bus that need open and the air-conditioning unit that needs monitoring, like this, can comprise the sign of the bus that need enable and the sign of need watch-dog in the equipment configuration-direct of generation.
Step 23: receive control instruction.This control instruction is used for the air-conditioning unit of control chart 1.This control instruction can be to import in the man-machine interface by the calculation element 13 of operating personnel in Fig. 1, and control instruction for example can be start or the shutdown command to the air-conditioning unit, and for example can be the setting to the air-conditioning unit available machine time.
Step 25: the control data that generates the device protocol that meets the air-conditioning unit according to control instruction.According to different air-conditioning units, the control data here should adopt the device protocol of controlled air-conditioning unit.
Step 27: the packet that control data is encapsulated as default communications protocol sends to the air-conditioning unit then.For example, as adopting the RS232 agreement, then be encapsulated as the packet of RS232 agreement; As adopt ICP/IP protocol, then be encapsulated as the TCP/IP packet.Here the transmission of carrying out can be to be sent to communication interface device 12 earlier, is forwarded to communication module 11 by the latter, sends to controlled concrete air-conditioning unit 10 by communication module 11 again.
Above step 21-27 is finished by calculation element, after step 27, the air-conditioning unit can be adjusted self duty according to this control data, for example starts shooting, shuts down or set operational factor, also can be according to the time period that comprises in the control data, carry out action default in this time period.
In step 23, receive control instruction after, can preserve this control instruction earlier; In step 25, can be the control instruction that reads a preservation earlier specifically, confirm that this control instruction meets default authority, generate the control data of the device protocol that meets the air-conditioning unit then according to this control instruction.The authority here mainly is for safety that guarantees the air-conditioning unit or operation rationally.Operating personnel at first carry out user's login when the enterprising line operate of man-machine interface of calculation element 13, multiple user class can be set, and each rank has the operating right for the air-conditioning unit separately, promptly different opereating specifications.
The control instruction that calculation element sends can be used for controlling in the lump a plurality of air-conditioning units, and like this, before step 23, calculation element also will receive the grouping instruction, and this grouping instruction is used for a part of air conditioner assembly is changed to a group.Control instruction in the step 23 is specially group's control instruction, is used for controlling the group of configuration.The sign that contains communication module 11 in the step 27 in the packet of encapsulation, after communication module 11 is received packet, whether the sign in the judgment data bag is identical with self identification, if it is identical, then the control data in the packet is sent to the air-conditioning unit of connection, if difference then abandon this packet.
Fig. 3 is the flow chart according to the method for the supervision air-conditioning unit in the embodiment of the invention.Related data when promptly obtaining operation of air conditioner can be monitored according to flow process shown in Figure 3 from long-range to the air-conditioning unit.As shown in Figure 3, the method for the supervision air-conditioning unit in the embodiment of the invention mainly comprises the steps:
Step S31: communication module receives the packet of the device data that comprises the air-conditioning unit.The air-conditioning unit sends to communication module with the data of self, and these data are data of the device protocol form of air-conditioning unit.These data are encapsulated packet or the packet of ICP/IP protocol or the packet of other agreements that obtains the RS232 agreement by communication module.
Step S33: the communications protocol of the data/address bus that adopts according to the communication interface device is resolved the device data that the packet of receiving obtains meeting the device protocol of air-conditioning unit.
Step S35: preserve device data, perhaps according to device data output equipment operation information.This output can be that the man-machine interface by calculation element shows.
Below again the system of the control air-conditioning unit in the present embodiment and the system of supervision air-conditioning unit are illustrated respectively.
