The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to the specific circumstances.
The embodiment of the invention shown in fig. 1 discloses a multi-split air conditioning unit, which comprises an outer machine 10, a plurality of inner machines 20 and a control device, wherein the outer machine 10 is connected with the inner machines 20 to form a refrigerant compression cycle, so that refrigeration or heating is realized. The control device is respectively in communication connection with the external machine 10 and the plurality of internal machines 20, thereby realizing the control of the external machine 10 and the internal machines 20. The control device may be a control circuit board on the external machine 10 and/or the internal machine 20, and the control circuit board is in communication connection with components such as a four-way valve, an electronic expansion valve, a fan, and the like, so as to control each component.
In addition, the multi-split air conditioning unit further includes a line controller 40 and a control module. The line controller 40 is in communication connection with the control device, and can give a control instruction to the control device through the line controller 40, and the control device controls the internal machine 20 according to the content of the control instruction after receiving the control instruction given by the line controller 40. The control module is also in communication connection with the control device, and is used for issuing control instructions to the control device according to the conditions in the room, so that the control of indoor temperature, wind speed and working modes is realized, for example: emergency switches, infrared human senses, house cards, etc. When the centralized control is performed, the upper computer 30 is required to be in communication connection with the control device through the gateway 50, when the upper computer 30 gives a control instruction to the control device, the control instruction is transmitted to the control circuit board through the gateway 50, and each component is regulated through the control circuit board, so that the control of indoor temperature, wind speed and working mode is realized.
It should be noted that, in this embodiment, one external machine 10 and a plurality of internal machines 20 form a unit, and the multi-connected air conditioner unit may include a plurality of units, where each unit is connected to an upper computer through a respective gateway in a communication manner.
The control method of the multi-split air conditioning unit comprises the following steps:
s10: after receiving the centralized control instruction of the upper computer 30, controlling the inner machine 20 of the multi-connected air conditioning unit to enter a centralized control mode according to the received centralized control instruction;
s20: and in the centralized control mode, checking all received control instructions, and selectively executing the received control instructions according to the checking result.
When the multi-split air conditioning unit is required to enter the centralized control mode, a centralized control instruction is sent out through the upper computer 30, the centralized control instruction is transmitted to the control device through the gateway 50, and the control device controls the inner machine 20 to enter the centralized control mode after receiving the centralized control instruction. In the centralized control mode, the control device checks all received control instructions, and selectively executes the received control instructions according to the checking result.
According to the control method of the multi-split air conditioner unit, after the multi-split air conditioner unit enters the centralized control mode, when the control device receives the control instruction again, the control device does not immediately execute the received control instruction, but checks the received control instruction first, and only after the check is passed, the corresponding control instruction is executed. If the check fails, the received control instruction is not executed. Compared with the prior art, the verification link is added, and the control command sent by the equipment in the room can be controlled by setting the verification standard during use, so that the real centralized control is realized, the centralized control of an administrator is facilitated, and the experience of the centralized administrator is improved.
Further, the step S10 further includes the steps of:
the operation parameters and/or operation modes of the internal machine 20 are set according to the control instructions of the upper computer 30 while the internal machine 20 is controlled to enter the centralized control mode.
While the control device controls the internal machine 20 to enter the centralized control mode, the operation parameters of the internal machine 20 are set according to the content of the control command of the upper computer 30, for example: the outlet air temperature, wind speed, etc., or the operation mode of the internal machine 20, for example: cooling mode, heating mode, dehumidification mode, etc. When the centralized control mode is entered, the control device sets the operation parameters and/or the operation modes of the internal machine 20 according to the content in the centralized control instruction, so that the internal machine 20 in the centralized control mode is uniformly controlled, repeated setting of the internal machine 20 is avoided, operation steps are simplified, and operation efficiency is improved.
In order to ensure the experience of the authority of the centralized manager, in the above steps, the authority of the control instruction of the upper computer 30 is set to the highest level, so as to avoid that the control instruction of the upper computer 30 is covered by the control instructions of other devices.
After entering the centralized control mode, although the control command issued by the line controller 40 in the room is filtered by the control device, the line controller 40 may be used from the user's perspective, but after being set by the line controller 40, the internal machine 20 does not react, so the user experience is easily affected.
In order to avoid the above, the following steps are further included in step S10:
the line controller 40 of the internal unit 20 is locked while controlling the internal unit 20 to enter the centralized control mode. When the control device controls the internal machine 20 to enter the centralized control mode, the control device locks the line controller 40 of the internal machine 20, so that the line controller 40 cannot input control instructions, and the operation interface of the line controller 40 displays that the internal machine 20 enters the centralized control mode, so that a user knows that the line controller 40 of the internal machine 20 has entered the locked state, thereby avoiding the reduction of user experience.
Further, the step S20 specifically includes the steps of:
s21: in the centralized control mode, verifying the sources of all received control instructions; if the source of the received control instruction is the upper computer 30, executing the received control instruction; if the source of the received control instruction is the non-upper computer 30, checking the content of the received control instruction;
s22: and selectively executing the control instruction according to the verification result.
The "check the received control instruction content" in step S22 specifically includes the steps of:
identifying the content of the received control instruction and comparing the content with the content of the control instruction currently running;
the step S22 specifically includes the following steps:
if the content of the received control instruction is consistent with the content of the control instruction currently operated, executing the received control instruction;
if the content of the received control instruction is inconsistent with the content of the control instruction currently operated, continuing to execute the control instruction currently operated.
In the centralized control mode, when the control device receives the control instruction, the control device firstly checks the source of the control instruction, and if the source of the control instruction is the upper computer 30, that is, the control instruction is sent by the upper computer 30, the control device executes the control instruction; if the source of the control instruction is found to be not the upper computer 30 after verification, but the control instruction (for example, the control instruction sent by the indoor control module according to the condition of the indoor user is sensed by the infrared person), the control device can identify the content of the control instruction and compare the content of the control instruction with the content of the control instruction currently operated, and if the content of the control instruction is consistent with the content of the control instruction currently operated, the control device executes the received control instruction; if the content of the control instruction is inconsistent with the content of the control instruction which is currently running, continuing to execute the control instruction which is currently running.
After the control instruction is received by the control device, the control instruction is checked, and the control instruction is selectively executed or the content of the control instruction is compared with the currently executed instruction according to the checking result. If the control instruction content is selected to be compared with the currently executed instruction content, selecting whether to execute the received control instruction or continue to execute the currently executed control instruction according to the comparison result. Therefore, the command of the upper computer 30 and the command which is the same as the command of the upper computer 30 can be filtered out from the command received by the control device and executed, so that the control command of the upper computer 30 is prevented from being covered by the control command of other devices, and the internal machine 20 is prevented from being separated from the centralized control of the upper computer 30.
In another embodiment of the present disclosure, the control method is substantially the same as the above embodiment, except that the following steps are specifically included in step S20:
s23: in the centralized control mode, verifying the sources of all received control instructions;
acquiring a source address code of the received control instruction, and comparing the acquired source address code with an address code of the upper computer 30;
if the source address code is consistent with the address code of the upper computer 30, the verification result is that the received control instruction is from the upper computer 30;
if the source address code is inconsistent with the address code of the upper computer 30, the verification result is that the received control command is from the non-upper computer 30.
S24: and selectively executing the control instruction according to the verification result.
If the verification result is that the received control instruction is from the upper computer 30, executing the received control instruction;
if the check result is that the received control instruction is from the non-host computer 30, the received control instruction is not executed.
In this embodiment, in the centralized control mode, when the control device receives the control command, the source address code of the control command is obtained first, and the source address code is compared with the address code of the upper computer 30, so as to determine whether the source of the control command is the upper computer 30, and if the source address code is consistent with the address code of the upper computer 30, the control command is executed; if the source address code is not consistent with the upper computer 30 address code, the received control command machine is not executed. By the judging method, the control instructions of the upper computer 30 can be directly filtered and executed, and the control sent by the equipment except the upper computer 30 is not executed uniformly, so that the control instructions of the upper computer 30 are effectively prevented from being covered by other equipment, the real centralized control is realized, and the control experience of an administrator is improved.
