Further, it should be noted that this specification describes many features. Although some features may be combined to show a possible system design, these features may also be used in other combinations not explicitly described. Thus, the combinations illustrated are not intended to be limiting unless otherwise specified.
The invention relates to a control system of a unit network relationship, which comprises: a terminal and a control center.
The terminal is connected with the unit and periodically acquires basic information of equipment of the unit. In one embodiment, the terminal may be a communication module in the unit (i.e., a hardware module that is provided when the unit leaves a factory), and the communication module may be a wired communication module or a wireless communication module. In another embodiment, the terminal may be a communication module independent from the unit (i.e., an external hardware module that can be plug and play after the unit leaves a factory), and similarly, the communication module independent from the unit may also be a wired communication module or a wireless communication module.
The control center is used for monitoring the unit network relationship, and meanwhile, according to the unit network relationship, a user can realize remote control of the air conditioning unit through mobile terminals such as a mobile phone and the like by means of the terminal. The specific hardware carrier of the control center can be a server, a server cluster or a host.
The control center is provided with a temporary storage area and a unit network relation data area. The temporary storage area is mainly used for storing basic information of the equipment of the unit in an online state, the unit network relationship data area is used for storing the network relationship of the unit, the online state or the offline state of the equipment of the unit, the basic information of the equipment of the unit, and the basic information of the equipment of the unit can comprise a unique identification code of the equipment of the unit, some running data of the equipment of the unit and the like. The equipment of the unit refers to an inner unit and an outer unit of the unit. In one embodiment, the devices of the assembly may further comprise a terminal.
The control center regularly receives basic information of the equipment of the unit acquired by the terminal, obtains the network relationship of the unit according to the basic information of the equipment of the unit acquired at the current time, ensures that the basic information of the equipment of the unit acquired at the current time is stored in the temporary storage area and the unit network relationship data area, simultaneously sets the state of the corresponding equipment in the network relationship of the unit to be an online state, then judges whether the basic information of the equipment of the unit stored in the temporary storage area has basic information of the equipment which is inconsistent with the basic information of the equipment of the unit acquired at the current time, and if so, sets the state of the equipment which is inconsistent with the basic information of the equipment of the unit acquired at the current time to be an offline state.
Through the technical scheme, the network relationship of the unit and the relationship between the equipment of the unit and the terminal can be updated in time, the trouble caused by manual input of the network relationship of the unit is avoided, and the problem that the network relationship of the unit is not updated in time due to the fact that the equipment of the unit is replaced or parts are replaced in the using process of the unit is solved.
The equipment of the unit comprises an inner unit of the unit and an outer unit of the unit, and the network relation of the unit is actually the connection relation between each inner unit and the outer unit in an air conditioning system. When the terminal is a communication module independent of the terminal, the network relationship of the terminal may further include a connection relationship between the terminal and the external unit. As shown in fig. 1, which is a schematic structure of a network relationship of a unit, it can be known from the technical solution of the present invention that an external unit is connected to a terminal M1 and a terminal M2, the external unit is also connected to an internal unit 1 to an internal unit n, the internal unit can communicate with the external unit through wireless and/or wired communication, and a wireless communication module of the internal unit is W1-Wn in the figure.
In one embodiment, the terminals include a first terminal in wired connection with the crew and a second terminal in wireless connection with the crew. When the remote control system works normally, the first terminal and the second terminal acquire and send data simultaneously, if one terminal is damaged and does not work, the other terminal still acquires and sends data normally, and reliability of remote control of a user is guaranteed.
In one embodiment, when the control center receives the basic information of the equipment of the current unit, the basic information of the equipment of the currently acquired unit is ensured to be stored in both the temporary storage area and the unit network relation data area, and the state of the equipment of the unit is updated, the main implementation process is to firstly judge whether the corresponding basic information of the equipment exists in the temporary storage area. For example, the determination may be specifically made as to whether the unique identifier of the indoor unit exists in the unit in the temporary storage area, or whether the unique identifier of the outdoor unit exists in the play set in the temporary storage area.
And if the unique identification code of the corresponding internal unit or the external unit is stored in the temporary storage area, directly updating the state of the equipment of the corresponding unit to be an online state. For example, when a certain internal machine is originally in an online state, the online state of the internal machine is maintained. If a certain internal machine is in an off-line state, the internal machine is changed into an on-line state.
If the unique identification code of the corresponding internal machine or the corresponding external machine is not stored in the temporary storage area, whether the basic information of the corresponding equipment exists in the unit network relation data area is judged, if not, the basic information of the equipment of the corresponding unit is newly added to the temporary storage area and the unit network relation data area, and then the state of the corresponding equipment is set to be an online state; if yes, the basic information of the equipment of the corresponding unit is newly added to the temporary storage area, and then the state of the corresponding equipment is set to be an online state.
For example, if a certain internal machine is newly added to the machine set, then in the data acquisition process of the just added internal machine, the unique identification code of the internal machine is inevitably not stored in the temporary storage area, then it is determined whether the unique identification code of the internal machine is stored in the machine set network relationship data area, because the internal machine is newly added, and then the unique identification code of the internal machine is also inevitably not stored in the machine set network relationship data area, then the unique identification code of the internal machine is newly added to the temporary storage area and the machine set network relationship data area, and meanwhile, the internal machine is newly added in the machine set network relationship, and the online state of the internal machine in the network relationship is set as the online state.
For another example, a certain internal machine is in an online state before, but in the latest data acquisition process, the internal machine is turned off, so that the latest data acquisition process does not necessarily include the unique identification code of the internal machine, and when the control center compares the unique identification code of the internal machine existing in the unit in the temporary storage area, the control center finds that the unique identification code of the internal machine does not appear in the latest acquired data, and deletes the unique identification code of the internal machine from the temporary storage area. And then, in the unit network relationship, setting the state of the internal unit of the unit as an offline state.
In one embodiment, the temporary storage area includes a fast cache area having a storage speed on the order of microseconds and a permanent cache area having a storage speed less than that of the fast cache area. The fast cache region is temporary, data in the fast cache region can be read and written at a speed of microsecond level for caching, the permanent cache region is a region which is read and written at a slow speed relative to the read and write speed of the fast cache region, and the permanent cache region can transfer basic information of equipment of a corresponding unit into a disk at regular time, namely, the basic information is stored in a unit network relation data set in the disk.
When two different cache areas exist in the temporary storage area, the control center judges whether the temporary storage area has basic information of corresponding equipment, firstly judges the fast cache area and then judges the permanent cache area.
If the basic information of the corresponding equipment is stored in the quick cache region, directly updating the state of the equipment of the corresponding unit to be an online state;
if the basic information of the corresponding equipment is not stored in the fast cache region and the basic information of the corresponding equipment is stored in the permanent cache region, the basic information of the new equipment is added into the fast cache region, and the state of the equipment of the corresponding unit is updated to be an online state.
In the above technical solution, when determining whether the basic information of the device of the unit stored in the temporary storage area is not included in the basic information of the device of the unit collected this time, specifically, determining whether the basic information of the device not included in the basic information of the device of the unit collected this time is stored in the fast cache area. For example, when it is required to determine whether an internal unit is in an offline state from an online state, it is determined whether the internal unit is originally stored in the fast cache region, if the internal unit is originally stored in the fast cache region, it is determined that the internal unit is in the online state, it is determined whether the basic information of the device of the unit collected this time includes the unique identification code of the internal unit, and if the basic information does not include the unique identification code, it is determined that the internal unit is in the offline state, so that the state of the internal unit needs to be updated in time, so as to prevent the control instruction of the user from being unable to be honored.
The control system of the unit network relationship comprises a visual interactive interface besides a terminal and a control center, wherein the visual interactive interface can be an operation interface of application software (APP). For example, a user may install corresponding application software on a mobile terminal such as a mobile phone or a computer of the user, where the application software provides a visual interactive interface, and the visual interactive interface may display a unit network relationship, for example, a unit network relationship diagram as shown in fig. 1.
When a user selects the corresponding equipment in the unit network relationship and inputs the corresponding control instruction, the control center transmits the corresponding control instruction to the corresponding equipment according to the unit network relationship, and the corresponding control instruction is displayed in the visual interactive interface through the response result of the terminal acquisition equipment. For example, if a user selects the internal machine 1 and inputs a corresponding control instruction that the temperature is 25 ℃ in a refrigeration mode, the corresponding control instruction is transmitted to a corresponding machine set from the control center through a terminal, and the machine set controls the corresponding internal machine, so that remote and accurate control of the user is realized. If a certain internal machine is in an off-line state, the internal machine is in a non-selectable state, and a user can not be executed even if a temperature control instruction is sent except for controlling the internal machine to be started up firstly.
In one embodiment, the basic information of the device of the crew comprises a unique identification code of an internal unit of the crew, a unique identification code of an external unit of the crew, information of a terminal of the crew, and the like. The information of the terminal of the group may include a unique identification code of the terminal of the group, and the basic information of the device of the group may include operation data of the device (an internal device or an external device) and the like in addition to these.
In one embodiment, the unit network relationship data area stores a unit network relationship data set, the unit network relationship data set uses the unique identification code of the unit as a large category, uses the unique identification code of the equipment of the unit as a small category, and stores the corresponding information and state of each equipment. The information and the state of the equipment of the unit are stored in the unit network relation data set mode, and the problem that data storage in the existing data is disordered can be solved.
The detailed process of setting up the network relationship of the air conditioning unit according to the present invention will be described with reference to fig. 1 and fig. 3.
Firstly, each internal unit reports data to the external unit through wire and/or wireless, the terminal M1 and the terminal M2 simultaneously acquire basic information of the equipment of the unit and send the basic information of the equipment of the unit to an access service module of a control center, and the access service module receives the basic information of the equipment of the unit, for example, the basic information is transmitted to an access service by the terminal in the form of an information set Q1. The information set Q1 is data collected by the terminal M1 and the terminal M2 and sent to a server (control center), and includes corresponding information of the internal unit, and the corresponding information of the external unit is analyzed and then stored in the unit network relationship data set D1.
Then, the control center will first determine whether the fast cache region H1 has the unique identifier of the internal unit in the current information set Q1, and the unique identifier of the external unit, and if not, then determine whether the permanent cache region H2 has the unique identifier, if not, then determine whether the unit network relationship data set exists, if not, then obtain the unit network relationship based on the information set Q1, and add the basic information of the device of the unit into the two cache regions and record the basic information into the unit network relationship data set D1, the unit network relationship data set D1 specifically includes the connection relationship (i.e., the unit network relationship) between the internal unit and the external unit of the unit, the corresponding information of the terminal, and the basic information of the unit, wherein the basic information of the unit includes the corresponding information (e.g., the unique identifier of the internal unit) of the internal unit and the corresponding information (e., the unique identifier of the external unit) of the external unit.
If the corresponding unique identifier of the internal machine does not exist in the fast cache region H1, but the unique identifier of the internal machine exists in the permanent cache region H2, the corresponding information of the internal machine in the permanent cache region H2 is acquired and synchronized into the fast cache region H1, and meanwhile, the state of the internal machine is updated to be the online state, for example, the online state flag bit in the unit network relationship data set is true.
And then, judging whether the equipment in the fast cache region H1 exists in the information set Q1, if not, updating the state of the equipment of the unit to be an offline state, for example, setting the online state flag position of the corresponding internal unit in the unit network relationship data set to be False, and deleting the equipment of the unit in the offline state in the fast cache region H1 and the permanent cache region H2.
And finally, binding the relationship among the terminal M1, the terminal M2 and the equipment of the unit and updating the relationship to the unit network relationship data set D1, thus completely recording the network relationship of the air conditioning unit. For example: a unit network comprises 1 outdoor unit and 5 indoor units, a terminal reports information corresponding to 3 indoor units I1, I2 and I3 for the first time, information of the three indoor units is newly added to a temporary cache region and a unit network relation data set, corresponding information of the other two indoor units I4 and I5 is reported for the second time, a control center can automatically identify the information of the two newly added indoor units, the three previous indoor units are offline, and corresponding fields in the temporary cache region and the unit network relation data set are updated at the same time.
The following describes a process of implementing real-time point-to-point remote control of large concurrency of the air conditioning unit according to the present invention with reference to fig. 2 and fig. 4.
Suppose that a user needs to control the internal machine I5, the internal machine code is A1, namely I5 is the serial number of the internal machine, A1 is the unique identification code of the internal machine, the user needs to select the internal machine I5 on the visual system, and click the function needing to be controlled, such as remote monitoring and remote control of the operation of the unit. At the moment, the control center can obtain a machine set network relation data set, the bound inner machine code A1 is obtained through the unique identification code of the terminal, a user control command is written into the fast cache region, the fast cache region is transferred into the access service module, the access service module sends the code to the appointed terminal, the terminal sends the code to the inner machine with the code of A1 again, the corresponding inner machine makes a control response, the terminal collects the operation data of the inner machine and sends the operation data to the access service module, the data is transferred into the fast cache region and the permanent cache region after being analyzed, and the visual interaction interface displays the corresponding operation data to the user according to the operation data of the equipment of the machine set in the fast cache region. Therefore, the second-level data are read from the quick cache region and displayed on the visual interactive interface from the time when the user clicks and controls the internal unit I5 to the time when the data are collected and reported by the terminal, and the real-time point-to-point remote monitoring and remote control of the air conditioning unit are realized.
The above description is intended to be illustrative of the preferred embodiment of the present invention and should not be taken as limiting the invention, but rather, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
