Description

Technical Field

[0002] Commercial air conditioners usually need to remotely monitor air conditioner data, remotely control the air conditioner on and off, and remotely control the air conditioner's working mode through a computer. Usually, air conditioners use a master-slave communication method. For example, if there is an outdoor unit, an indoor unit, and a wired controller in the air conditioning network, the outdoor unit initiates the roll call, regularly calls the indoor unit, and then calls the wired controller. If remote control is required, it is agreed that the remote control device (such as a computer) will be called again, and the roll call will be repeated after a certain period of time (such as 500ms). The waiting time of 500ms is mainly due to the fact that the computer is a multi-threaded device, and there is a certain delay in receiving data, interpreting data, and replying. However, the defect of the above solution is that the efficiency of the air conditioner communication bus becomes low, and when the computer configuration is not high or is stuck, the control may fail, affecting the user experience.

[0062] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0063] Example 1

[0064] In a preferred embodiment 1 of the present invention, an air conditioner communication control method is provided, which is applied to a main device in an air conditioner communication network, and the main device at least includes an air conditioner outdoor unit; specifically, Figure 1 An optional flow chart of the method is shown as follows: Figure 1 As shown, the method includes the following steps S102-S110:

[0065] S102: sending roll call data frames to slave devices in the air conditioner communication network in a preset order; wherein the slave devices at least include a remote control terminal;

[0066] S104: receiving a reply frame returned from the device;

[0067] S106: when the reply frame is a data frame sent by the remote control terminal, judging whether the remote control terminal needs to send a control instruction to the main device according to the data frame;

[0068] S108: If yes, stop sending roll call data frames to other slave devices and receive control instructions sent by the remote control terminal;

[0069] S110: Otherwise, continue to send roll call data frames to other slave devices.

[0070] In the above implementation, a solution for improving the success rate of remote control is provided. When the main device, the air-conditioning outdoor unit, sends roll call data to the remote control terminal, the remote control terminal will first send a shorter data frame to inform the main device that there is refrigeration control that needs to be sent. At this time, the air-conditioning outdoor unit will become a slave device to be called, and the remote control terminal will become the master device. After the remote control terminal becomes the master device, it is no longer affected by the slow response of the computer device and the timing of the air-conditioning unit, and can freely control the air-conditioning unit. Therefore, it effectively solves the problem of easy failure of remote control in air-conditioning networking, improves the success rate of remote control, and at the same time improves the efficiency of the air-conditioning communication bus.

[0071] Figure 2 An optional schematic diagram showing the air conditioning communication control method is shown, such as Figure 2 As shown, when the master device calls out the slave device, it will call out the slave device in order and sequence. The slave device also includes at least one of the following: air conditioner indoor unit, wired controller, gateway. The timing setting is mainly considered for the remote control end. For example, a computer is a multi-threaded device, which has a certain delay in receiving data, interpreting data, and replying. Therefore, it waits for a certain time after calling out the name. The waiting time is the sequence. The timing can be set to 500 milliseconds or other time to receive the reply frame sent by the remote control end. If the reply frame is sent by a slave device other than the remote control end, perform the following operations: update the data of the air conditioner communication network according to the reply frame; continue to send the calling out data frame to other slave devices.

[0072] When calling the roll to the remote control end, if the remote control end does not have a control command to send, the remote control end will send data within 500 milliseconds to inform the master device that there is no control command to send, and the master device will continue to call the roll. When calling the roll to the remote control end, if the remote control end has a control command to send, the computer remote control will send a very short frame of data within 500 milliseconds to inform the master device that there is a control command to send. After receiving the master device, it determines that the remote control end has a control command, that is, it sends a handshake frame to inform the computer remote control end, and stops calling the roll data. At this time, the master device will become a slave. The remote control end automatically switches to the host. At this time, the remote control end is no longer restricted by the master device's roll call timing and can freely send control commands.

[0073] After receiving the control instruction sent by the remote control end, it also includes: monitoring whether the first communication frame sent by the remote control end is received; wherein the first communication frame is used to indicate that the control instruction has been sent; if so, continue to send the roll call data frame to other slave devices; otherwise, continue to receive the control instruction sent by the remote control end.

[0074] If the remote control terminal can send all control commands within X seconds, it will inform the master device through the communication frame that the sending is completed. At this time, the original master device becomes the master again, and the remote control terminal becomes the slave, entering the normal working state.

[0075] Monitor whether a second communication frame sent by the remote control terminal is received; wherein the second communication frame is used to indicate that the control instruction has not been sent completely; if yes, continue to send roll call data frames to other slave devices; otherwise, continue to receive the control instruction sent by the remote control terminal. After continuing to send roll call data frames to other slave devices, it also includes: after the roll call of other slave devices is completed, send a handshake frame to the remote control terminal to inform the remote control terminal to wait for receiving the control instruction.

[0076] If the remote control terminal fails to send all control commands within X seconds, it will stop sending control commands and inform the slave device through data frames (the time is up, but the control commands have not been sent). At this time, the original master device becomes the host again, and the remote control terminal becomes the slave, entering the normal working state. At this time, the master device continues to call out other devices in the network, with the purpose of re-updating the latest data of all units in a round of networking. After the data update is completed, a handshake frame is sent to inform the computer remote control terminal and stop calling out data. At this time, the master device will become a slave, and the remote control terminal will automatically switch to the host. At this time, the remote control terminal is no longer restricted by the master device's call out timing, and will continue to send the control commands that have not been sent within X seconds.

[0077] Optionally, before stopping sending roll call data frames to other slave devices, the method further includes: sending a handshake frame to the remote control terminal to inform the remote control terminal to wait for receiving a control instruction.

[0078] The above solution can improve the efficiency of the air conditioner communication bus, and effectively solve the problem that when the computer configuration is not high or there are too many threads during freezing, the control may fail.

[0079] Example 2

[0080] In a preferred embodiment 2 of the present invention, another air conditioner communication control method is provided, which is applied to a slave device in an air conditioner communication network, and the slave device at least includes a remote control terminal; specifically, Figure 3 An optional flow chart of the method is shown as follows: Figure 3 As shown, the method includes the following steps S302-S308:

[0081] S302: monitoring whether a roll call data frame sent by a master device in the air conditioning communication network is received;

[0082] S304: upon receiving the roll call data frame, determining whether a control instruction needs to be sent to the master device;

[0083] S306: If yes, sending a first reply frame to the master device within a first preset time; wherein the first reply frame is used to indicate that a control instruction needs to be sent;

[0084] S308: Otherwise, send a second reply frame to the master device within the first preset time; wherein the second reply frame is used to indicate that there is no need to send the control instruction.

[0085] In the above implementation, a solution for improving the success rate of remote control is provided. When the main device, the air-conditioning outdoor unit, sends roll call data to the remote control terminal, the remote control terminal will first send a shorter data frame to inform the main device that there is refrigeration control that needs to be sent. At this time, the air-conditioning outdoor unit will become a slave device to be called, and the remote control terminal will become the master device. After the remote control terminal becomes the master device, it is no longer affected by the slow response of the computer device and the timing of the air-conditioning unit, and can freely control the air-conditioning unit. Therefore, it effectively solves the problem of easy failure of remote control in air-conditioning networking, improves the success rate of remote control, and at the same time improves the efficiency of the air-conditioning communication bus.

[0086] After sending the first reply frame to the master device, the method further includes: monitoring whether a handshake frame sent by the master device is received; and sending a control instruction to the master device when the handshake frame is received.

[0087] After sending the control instruction to the main device, it also includes: starting timing; after the timing time reaches a second preset time, determining whether the control instruction has been sent; if so, sending a first communication frame to the main device; wherein the first communication frame is used to indicate that the control instruction has been sent; otherwise, stopping sending the control instruction and sending a second communication frame to the main device; wherein the second communication frame is used to indicate that the control instruction has not been sent.

[0088] After sending the second communication frame to the master device, the method further includes: monitoring whether a handshake frame sent by the master device is received; when the handshake frame is received, sending the unsent control instructions to the master device.

[0089] When calling the roll to the remote control end, if the remote control end does not have a control command to send, the remote control end will send data within 500 milliseconds to inform the master device that there is no control command to send, and the master device will continue to call the roll. When calling the roll to the remote control end, if the remote control end has a control command to send, the computer remote control will send a very short frame of data within 500 milliseconds to inform the master device that there is a control command to send. After receiving the master device, it determines that the remote control end has a control command, that is, it sends a handshake frame to inform the computer remote control end, and stops calling the roll data. At this time, the master device will become a slave. The remote control end automatically switches to the host. At this time, the remote control end is no longer restricted by the master device's roll call timing and can freely send control commands.

[0090] If the remote control terminal can send all control commands within X seconds, it will inform the master device through the communication frame that the sending is completed. At this time, the original master device becomes the master again, and the remote control terminal becomes the slave, entering the normal working state.

[0091] If the remote control terminal fails to send all control commands within X seconds, it will stop sending control commands and inform the slave device through data frames (the time is up, but the control commands have not been sent). At this time, the original master device becomes the host again, and the remote control terminal becomes the slave, entering the normal working state. At this time, the master device continues to call out other devices in the network, with the purpose of re-updating the latest data of all units in a round of networking. After the data update is completed, a handshake frame is sent to inform the computer remote control terminal and stop calling out data. At this time, the master device will become a slave, and the remote control terminal will automatically switch to the host. At this time, the remote control terminal is no longer restricted by the master device's call out timing, and will continue to send the control commands that have not been sent within X seconds.

[0095] The receiving module 404 is connected to the sending module 402 and is used to receive a reply frame returned from the device;

[0096] A first judgment module 406, connected to the receiving module 404, is used to judge whether the remote control terminal needs to send a control instruction to the main device according to the data frame when the reply frame is a data frame sent by the remote control terminal;

After the remote control terminal becomes the master device, it is no longer affected by the slow response of the computer device and the timing of the air-conditioning unit, and can freely control the air-conditioning unit. Therefore, it effectively solves the problem of easy failure of remote control in air-conditioning networking, improves the success rate of remote control, and at the same time improves the efficiency of the air-conditioning communication bus.
