Description

Method and device for controlling power failure recovery of air conditioning system and air conditioning system
Technical Field
The present application relates to the field of air conditioning technologies, and for example, to a method and an apparatus for controlling power failure recovery of an air conditioning system, and an air conditioning system.
Background
Power failure caused by faults, overhauls and the like of a power system is often encountered in life. When the power is recovered, if the state before the air conditioner continues to operate is required, the user is often required to control the air conditioner by himself. This way of controlling the restoration of the operation of the air conditioner is applicable to the home air conditioner. However, for some large places with multiple air conditioners, such as subway stations, it is inconvenient to manually set each air conditioner.
In the related art, the line controller stores the operation state of each internal machine. After the air conditioner is powered down and powered up, the wire controller sends the running state of each internal machine to the corresponding internal machine, so that the internal machine can continue to run according to the running state before the power down. By the mode, the running state of the air conditioner before automatic running and power failure after re-powering up is realized.
In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:
after the wire controller is powered on, the stored running state of the wire controller is sent to the internal machine, and no matter what state the internal machine is, namely the "blind sending" state of the wire controller. This approach can be complex for the drive-by-wire itself. If the control scheme is to be designed more precisely, the wire controller is required to store the number of each internal machine and the corresponding running state of the internal machine. This requires a high memory space for the drive-by-wire, and the design of the drive-by-wire is more complex.

The embodiment of the disclosure provides an air conditioning system, comprising: the system comprises a wire controller, one or more external machines and a plurality of internal machines. The external machine and the internal machine are connected through bus communication. In combination with fig. 1, only one of the plurality of internal machines is a main internal machine, and the other internal machines are sub internal machines. The main internal machine and each sub internal machine have own machine numbers, for example: the sub-internal machines # 0, the sub-internal machines # 1# … …, the sub-internal machines # 5 and the main internal machine # 6. The main internal machine and the sub internal machine are in communication connection with the wire controller through a bus. The internal machine comprises a first storage module, a CPU (central processing unit, a central processing unit), a wire controller bus communication module and the like. The wire controller comprises a display module, keys, a second storage module, a communication module and the like.
As shown in conjunction with fig. 2, an embodiment of the present disclosure provides a method for controlling power-down recovery of an air conditioning system, including:
s201, under the condition that the air conditioning system is powered on again, the line controller sends a power-down recovery instruction to the main internal machine and each sub internal machine so that the main internal machine and each sub internal machine can operate according to the operation state before power failure; the main internal machine and each sub internal machine store the running state before power failure.
S202, the line controller obtains the current running states of the main internal machine and each sub internal machine.
And S203, the line controller controls the running states of the sub-internal machines according to the current running states of the main internal machine and the sub-internal machines.
After the air conditioning system is powered down, if the power is recovered, the air conditioning system is powered up again. And after the wire controller is electrified, sending a power failure recovery instruction to the main internal machine and all the sub internal machines. The storage modules of the main internal machine and all the sub internal machines are respectively stored with the running states before power failure. When the main internal machine and each sub internal machine receive the power-down recovery instruction, the stored running state before power failure is called and is operated according to the stored running state. For example, in a mode prior to power failure, temperature, wind speed, etc. After the main internal machine and each sub internal machine are restored to operate, the wire controller obtains the current operating states of the main internal machine and each sub internal machine. The wire controller compares the current running state of the main internal machine with the current running state of each sub internal machine, and further controls the running state of each sub internal machine according to the comparison result.
In the embodiment of the disclosure, the running states of the main internal machine and each sub internal machine are stored by themselves. And after the air conditioning system is electrified, sending a power failure recovery instruction to the main internal machine and each sub internal machine. And after the main internal machine and each sub internal machine receive the power-down recovery instruction, the running state before power down is called from the respective storage module and runs according to the running state. Therefore, when the power-down memory function needs to be executed, all internal machines directly call the running state before power down from the respective storage modules. The operation states of all internal machines are not required to be stored by the wire controller, and the design difficulty of the wire controller is reduced. The wire controller further controls the running states of the sub-internal machines according to the current running states of the main internal machine and the sub-internal machines so as to achieve the purpose that one wire controller simultaneously controls a plurality of internal machines. Not only saves time, but also is more convenient.
The power down memory is actually the bit set by the dial of the drive-by-wire device, which is a 0/1 signal. 1 is a power-down memory valid bit, and after the internal machine is powered on and receives the signal, the stored parameters such as mode/temperature/wind speed before power failure are executed. And 0 represents a power-down memory invalid bit, and after the internal machine is powered on, the internal machine receives the signal to keep the power-off state and waits for the power-on control of the line controller.
As shown in conjunction with fig. 3, another method for controlling power-down recovery of an air conditioning system is provided according to an embodiment of the present disclosure, including:
s211, under the condition that the air conditioning system is powered on again, the line controller acquires addresses of the main internal machine and each sub internal machine.
S221, the line controller sends a power failure recovery instruction to the main internal machine and each sub internal machine according to the acquired address so that the main internal machine and each sub internal machine can operate according to the operation state before power failure; the main internal machine and each sub internal machine store the running state before power failure.
S202, the line controller obtains the current running states of the main internal machine and each sub internal machine.
And S203, the line controller controls the running states of the sub-internal machines according to the current running states of the main internal machine and the sub-internal machines.
And after the line controller is electrified, sending an address inquiry instruction to the main internal machine and each sub internal machine. The main internal machine and each sub internal machine respond to the address inquiry instruction. After the line controller receives the response information, the addresses of the main internal machine and the sub internal machines can be obtained. And then the line controller sends a power-down reply instruction to the main internal machine and each sub internal machine according to the acquired address. The main internal machine and each sub internal machine operate according to the operation state before power failure. Therefore, the line controller can accurately send the power failure recovery instruction to the main internal machine and each sub internal machine by inquiring the addresses of the main internal machine and each sub internal machine.
Optionally, in step S211, the line controller obtains addresses of the main internal unit and each sub internal unit, including:
the line controller obtains the main system number of the air conditioning system and the address of the main internal machine.
And the line controller acquires the addresses of all the sub-internal machines corresponding to the main system number according to the main system number.
After the wire controller is electrified, a query instruction is sent to the main internal machine so as to query the main system number and the main internal machine address. And after receiving the inquiry command, the main internal machine responds. The response information contains a main system number and a main internal machine address. After the line controller receives the response information, the main system number and the main internal machine address can be obtained. And the line controller sends inquiry instructions to all the internal machines (the main internal machine and the sub internal machines) according to the main system number so as to inquire the addresses of all the internal machines. At this time, all internal machines of the queried main system number queue the responses in a preset order. The response information includes addresses of all the internal machines. After the line controller receives the response information, the addresses of the main internal machine and each sub internal machine corresponding to the main system number can be obtained. The reason why the line controller obtains all the internal machine addresses according to the main system number is that: in practical applications, there are scenarios where the line controller controls across air conditioning systems. For example, 8 air conditioners in one room belong to a group of line controller controls, but these 8 air conditioners may belong to 2 systems. The internal machines need to be distinguished by the system number in order to accurately determine the addresses of the internal machines.
In connection with fig. 4, an embodiment of the present disclosure provides a method for controlling power down recovery of an air conditioning system, including:
s201, under the condition that the air conditioning system is powered on again, the line controller sends a power-down recovery instruction to the main internal machine and each sub internal machine so that the main internal machine and each sub internal machine can operate according to the operation state before power failure; the main internal machine and each sub internal machine store the running state before power failure.
S202, the line controller obtains the current running states of the main internal machine and each sub internal machine.
S213, the line controller controls the sub-internal machine to operate according to the operation state of the main internal machine when the current operation state of the sub-internal machine is inconsistent with the operation state of the main internal machine.
S223, the line controller controls each sub-internal machine to continue to operate in the current operation state under the condition that the current operation state of each sub-internal machine is consistent with the operation state of the main internal machine.
And the line controller compares the current running state of each sub-internal machine with the current running state of the main internal machine. If the current running states of the sub-internal machine and the main internal machine are inconsistent, the line controller sends the current running state of the main internal machine to the sub-internal machine so that the sub-internal machine runs according to the running state of the main internal machine. And if all the sub-internal machines are consistent with the current running state of the main internal machine, the line controller controls each sub-internal machine to continue to run in the current running state. Thus, under the condition that the running states of the sub-internal machine and the main internal machine are different, the running states of all the internal machines are consistent by controlling the sub-internal machine to run according to the running state of the main internal machine. Therefore, the purposes that the drive-by-wire controller is multiple in one control mode, the air conditioner is recovered to operate after the air conditioning system is electrified, and the operation states of all the sub-internal machines are controlled simultaneously are achieved.
Optionally, in step S213, the wire controller controls the sub-internal unit to operate according to the operation state of the main internal unit, including:
the line controller controls all the sub-internal machines to operate according to the operation state of the main internal machine; or the line controller controls the sub-internal machines with inconsistent running states to run according to the running states of the main internal machine.
If the current running states of the sub-internal machines and the main internal machine are inconsistent, the sub-internal machines with inconsistent control states are required to run according to the running states of the main internal machine. There are two implementations, the first is broadcast setting: the line controller sends the running state of the main internal machine to all the sub internal machines so as to control all the sub internal machines to run according to the running state of the main internal machine. In practice, of course, only the running states of the sub-internal machines with inconsistent states are changed to be consistent with the running states of the main internal machine. The second way is a single setting: the line controller determines the sub-internal machines with inconsistent states through the main system number and the internal machine number, and sends the running states of the main internal machines to the sub-internal machines with inconsistent states so as to control the sub-internal machines with inconsistent states to run according to the running states of the main internal machines. The two modes are different in that the target objects of the running state of the main internal machine sent by the wire controller are different. The appropriate mode can be selected according to actual requirements. For example, if the number of the internal machines with inconsistent states is greater than or equal to the preset number, the first mode is adopted. And if the number of the sub-internal machines with inconsistent states is smaller than the preset number, adopting a second mode. Alternatively, the preset number is 2. So as to improve the control efficiency.
It should be noted that, the method provided in this embodiment is also applicable to a "one-control-one" scenario, that is, a scenario with only one internal machine, where the internal machine is the main internal machine. Only when the internal machine responds, only the main internal machine responds.
Referring to fig. 5, in practical application, after the air conditioning system is powered on again, the communication and power failure memory implementation process of the wire controller is as follows:
s501, the line controller sends a preset broadcast query frame A to the main internal machine to query the main system number and the main internal machine address.
S502, the main internal machine response data frame B sends the main system number and the main internal machine address to the line controller.
S503, the line controller sends a data frame C, and broadcasts the main internal machine number and the main system number to all the sub internal machines (in this way, all the sub internal machines are clearly the number internal machines, the main internal machine is the number system, and preparation is made for subsequent subsystem group control response).
After 5 seconds, the drive-by-wire transmits a broadcast query frame D by system number S504.
S505, the main internal machine of the inquired system number and each sub internal machine order answer their own addresses (answer feature is that the internal machines of the small number answer first, the internal machines of the adjacent number answer 1ms apart).
S506, the line controller acquires the addresses of the main internal machine and each sub internal machine, transmits a broadcast setting frame E and transmits the power-down memory valid bit to the main internal machine and the sub internal machine.
S507, the main internal machine and each sub internal machine queue to answer to receive the confirmation frame and operate according to the operation state before power failure stored in each storage module.
S508, the line controller sends a single query frame F to query the running state of each internal machine.
S509, the queried main internal machine and each sub internal machine answer the current running state.
S510, the line controller inquires all the internal machines and compares the operation state of the main internal machine response with the operation state of each sub machine response; if there are different, the working state of the master internal machine is broadcasted under the setting.
S511, all the sub-internal machines receive the instruction and execute the same working state as the main internal machine.
Thus, the power-on and power-off memory function of the multi-on-line drive-by-wire controller one-control-multi-system is completed.
Referring to fig. 6, an embodiment of the present disclosure provides an apparatus for controlling power-down recovery of an air conditioning system, including: a transmitting module 61, an acquiring module 62 and a control module 63. The sending module 61 is configured to send a power-down recovery instruction to the main internal machine and each sub internal machine in the case of power-down of the air conditioning system, so that the main internal machine and each sub internal machine execute an operation state before power-down; the main internal machine and each sub internal machine store the running state before power failure. The acquisition module 62 is configured to acquire the current operating states of the main internal machine and each of the sub internal machines. The control module 63 is configured to control the operation state of each of the sub-internal machines according to the current operation states of the main internal machine and each of the sub-internal machines.
By adopting the device for controlling the power-down recovery of the air conditioning system, which is provided by the embodiment of the disclosure, the running states of the main internal machine and each sub internal machine are stored automatically. And after the air conditioning system is electrified, sending a power failure recovery instruction to the main internal machine and each sub internal machine. And after the main internal machine and each sub internal machine receive the power-down recovery instruction, the running state before power down is called from the respective storage module and runs according to the running state. Therefore, when the power-down memory function needs to be executed, all internal machines directly call the running state before power down from the respective storage modules. The operation states of all internal machines are not required to be stored by the wire controller, and the design difficulty of the wire controller is reduced. The wire controller further controls the running states of the sub-internal machines according to the current running states of the main internal machine and the sub-internal machines so as to achieve the purpose that one wire controller simultaneously controls a plurality of internal machines.
