The method includes: checking whether operation status data of a main control module is received; the operation status data is generated by the main control module when it is in an operating state and sent through a status data thread; if the operation status data is received, then keep running, and if the operation status data is not received, then enter a sleep state. The state of the wireless control module is made to follow the state of the main control module. When the main control module is in an operating state, the wireless control module also keeps running. When the main control module is in a sleep or shutdown state, the wireless control module also enters a sleep state, avoiding a startup error caused by the main control module still being in operation while the wireless control module has already entered a sleep state.

Description

Technical Field

[0001] This application relates to the field of control technologies, and particularly to a sleep control method for a wireless control module, a projector, and a storage medium. Background Art

[0002] In electronic products including a wireless control module (such as a Bluetooth module, a WiFi module, a ZigBee module, etc.), when the main control module of the electronic product receives a shutdown instruction sent by the user through the wireless control module, the main control module will save all the processes still running in the electronic product in the memory and wait for the next time the electronic product is awakened. At the same time when the main control module receives the shutdown instruction, it will send a sleep instruction to the wireless control module synchronously or after a preset time delay. The wireless control module enters the sleep state when it receives the sleep instruction and waits for the next wake-up signal.

[0003] For the above operation mode of the electronic product, if there are many programs running on the electronic product, the main control module needs to consume more time to save all the running processes. If the main control module has sent a sleep instruction to the wireless control module to make it enter the sleep state before saving all the running processes. During the process that the wireless control module is in the sleep state and the main control module is still saving processes, if the user sends a power-on instruction to the wireless control module through the remote control, the wireless control module is awakened and sends a power-on instruction to the main control module synchronously once. However, since the main control module is still in the process of saving processes, the main control module will not respond to this power-on instruction. Even if the user subsequently sends a power-on instruction to the awakened wireless control module through the remote control again, the wireless control module will not send a power-on instruction to the main control module again, and finally a power-on error occurs. Summary of the Invention

[0004] Based on this, it is necessary to provide a sleep control method for a wireless control module, a projector, and a storage medium that can avoid power-on errors for the above technical problems.

[0005] A sleep control method for a wireless control module includes the following steps:

[0006] Check whether the operation status data of the main control module is received; the operation status data is generated by the main control module when it is in the operation state and sent through the status data thread;

[0007] If the operation status data is received, keep running; if the operation status data is not received, enter the sleep state.

[0008] In one embodiment, the method includes:

[0009] After the main control module has shut down and / or saved the system processes, it stops sending the operating status data.

[0010] In one embodiment, in the step of checking whether the operating status data is received:

[0011] At every interval of a first preset period, check whether the operating status data is received; the operating status data is generated by the main control module when it is in the operating state and is sent through the status data thread.

[0012] In one embodiment, in the step of checking whether the operating status data is received:

[0013] When receiving the sleep instruction sent by the main control module, at every interval of a first preset period, check whether the operating status data is received; the operating status data is generated by the main control module when it is in the operating state and is sent through the status data thread.

[0014] In one embodiment, after the step of checking whether the operating status data is received, the following steps are further included:

[0015] If the operating status data sent by the main control module is received, update the temporary status bit to the first status bit;

[0016] If the operating status data sent by the main control module is not received, update the temporary status bit to the second status bit;

[0017] Check the temporary status bit to determine whether the operating status data sent by the main control module is received;

[0018] In the step of remaining in operation if the operating status data is received and entering the sleep state if the operating status data is not received:

[0019] If the temporary status bit is the first status bit, remain in operation; if the temporary status bit is the second status bit, enter the sleep state.

[0020] In one embodiment, after the step of remaining in operation if the temporary status bit is the first status bit and entering the sleep state if the temporary status bit is the second status bit, the following steps are further included:

[0021] Clear the temporary status bit.

[0022] In one embodiment, after the step of entering the sleep state if the operating status data is not received, the following steps are further included:

[0024] When responding to the wake-up signal, send the power-on signal to the main control module.

[0025] In one embodiment, the operating state data is generated by the main control module at intervals of a second preset period during the operating state and sent through the state data thread.

[0026] A computer-readable storage medium stores a computer program thereon. When the computer program is executed by a processor, the steps of the above method are implemented. An electronic product includes a wireless control module and a main control module;

[0027] When the main control module is in the operating state, it sends operating state data to the wireless control module. When the system process is closed or saved, it stops sending operating state data to the wireless control module;

[0028] The wireless control module checks whether it has received the operating state data sent by the main control module of the electronic product;

[0029] If the wireless control module receives the operating state data, it remains in the operating state. If it does not receive the operating state data, it enters the sleep state.

If the wireless control module in the electronic product does not receive the operating state data, it enters the sleep state. In the sleep control method of this application, the wireless control module determines the operating state of the main control module based on whether it has received the operating state data. If it receives the operating state data, the main control module is in the operating state. If it does not receive the operating state data, the main control module is in the sleep or shutdown state, so as to realize that the state of the wireless control module follows the state of the main control module. When the main control module is in the operating state, the wireless control module also remains running. When the main control module is in the sleep or shutdown state, the wireless control module also enters the sleep state, avoiding the startup error caused by the main control module still running while the wireless control module has entered the sleep state. The technical solution of this application is aimed at the situation where the device is shut down and then quickly powered on, and can more significantly and effectively avoid the problem of startup errors caused by the asynchronous sleep of the wireless control module and the main control module according to the above technical effects.

[0038] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] The sleep control method for a wireless control module provided by the present application can be applied to an application environment as Figure 1 shown. Among them, the electronic product 10 is a product including a wireless control module 101 and a main control module 103. For example, the electronic product 10 is a projector, a smart TV, a game console, a computer, etc. In addition to being electrically connected, the wireless control module 101 and the main control module 103 are also additionally provided with a status data thread 105. The wireless control module 101 receives a control signal wirelessly input by an external controller and forwards the control signal to the main control module 103. The wireless control module 101 also receives the control signal of the main control module 103. It should be noted that the wireless control module 101 is a Bluetooth module, a WiFi (Wireless-Fidelity) module, a ZigBee (ZigBee protocol) module, etc. The main control module 103 is an MCU (Microcontroller Unit).

[0040] In one embodiment, as Figure 2 shown, a sleep control method for a wireless control module is provided. Taking the method applied to the Figure 1 terminal as an example, the method includes the following steps:

[0041] Step S21, check whether the operation status data of the main control module is received; the operation status data is generated by the main control module when it is in the operation state and is sent through the status data thread.

[0042] The operating status data is used to represent the operating status of the main control module of the electronic product. The operating status of the main control module is either running a program or saving a process. When the main control module is in an active state or an operating state, it generates operating status data and transmits the operating status data to the wireless control module. When the main control module is in a shutdown or sleep state, the main control module does not generate operating status data. In one example, the operating status data can be pulse signal data. When the main control module is in an operating state, it continuously sends pulse signal data to the wireless control module to notify the wireless control module that the main control module is in an operating state.

[0043] Among them, the main control module sends the operating status data to the wireless control module through the status data thread. It should be noted that the status data thread is a thread specifically set between the main control module and the wireless control module in addition to the original threads of the wireless control module of this application to implement the sleep control method of the wireless control module, and is specifically used for the main control module to send the operating status data to the wireless control module. Specifically, the status data thread between the main control module and the wireless control module can be implemented through any of the following interfaces: usb (Universal Serial Bus), pcie (peripheral component interconnect express), uart (Universal Asynchronous Transmitter), or sdio (Secure Digital Input and Output).

[0044] In order to reduce the occupancy of the main control module and relieve the burden on the main control module, in one example, the operating status data is generated by the main control module of the electronic product at intervals of a second preset period when it is in an operating state and is sent through the status data thread. In other words, the main control module generates the operating status data once every second preset period. In one example, the second preset period is 0.5 seconds, 1 second, 1.5 seconds, etc. The specific second preset period can be set according to actual needs. The above specific periods are for illustrative purposes only and do not constitute a limitation on the second preset period.

[0045] The wireless control module checks whether it has received the operating status data to determine whether the main control module is in the operating state, the shutdown state, or the sleep state. Specifically, if the wireless control module checks that it has received the operating status data, it determines that the main control module is in the operating state. If the wireless control module checks that it has not received the operating status data, it determines that the main control module is in the shutdown state or the sleep state. In the example where the main control module has an interval of a second preset period, if the wireless control module has not received the operating status data for a duration exceeding the second preset period after the previous receipt of the operating status data, it determines that the main control module is in the shutdown state or the sleep state.

[0046] In one example, after the main control module has completed shutting down and / or saving the system processes, it stops sending the operating status data to the wireless control module. In the step of checking whether the operating status data has been received: when it is checked that the operating status data has not been received, it is determined that the main control module of the electronic product has completed shutting down or saving the system processes. It should be noted that in the preparation stage of shutdown or sleep of the main control module, the main control module needs to save all processes and shut down all processes. After the main control module has saved all processes or shut down all processes, the main control module will not send the operating status data to the wireless control module. At this time, the wireless control module can determine that the main control module has completed shutting down or saving the system processes, and can also determine that the main control module has entered the shutdown state or the sleep state.

[0047] In order to reduce the occupancy of the sleep control method of the wireless control module in this application on the wireless control module, in one example, in the step of checking whether the operating status data has been received: every interval of a first preset period, it is checked whether the operating status data has been received. Among them, the operating status data is generated by the main control module of the electronic product when it is in the operating state and is sent through the status data thread. In one example, the first preset period is 0.5 seconds, 1 second, 1.5 seconds, 2 seconds, 3 seconds, etc. The specific first preset period can be set according to actual needs. The above specific periods are for example purposes and do not constitute a limitation on the first preset period. In one example, the wireless control module starts a timer for timing to achieve the timing of the first preset period.

[0048] In order to further reduce the occupation of the wireless control module by the sleep control method of the present application and reduce energy consumption. In one example, in the step of checking whether the operating status data is received: when a sleep instruction sent by the main control module of the electronic product is received, every other first preset period, it is checked whether the operating status data is received. Among them, the operating status data is generated by the main control module of the electronic product when it is in the operating state and is sent through the status data thread. It should be noted that it is easy to have abnormal startup situations, that is, when the main control module is in the preparation stage of entering sleep or shutdown, and the main control module is saving and closing the system processes, the wireless control module has already entered the sleep or shutdown state. Therefore, in this example, the wireless control module only starts to check whether the operating status data is received every other first preset period when it receives the sleep instruction sent by the main control module of the electronic product, so that the wireless control module specifically monitors the preparation stage of the main control module entering sleep or shutdown, realizing the reduction of the occupation of the wireless control module and the reduction of energy consumption. It should be noted that when the main control module is in the preparation stage of entering sleep or shutdown, it will actively send a sleep instruction to the wireless control module to control the wireless control module to enter sleep. The wireless control module of the present application enters the sleep state only when the conditions of receiving the sleep instruction and not detecting the operating status data are met, so as to realize the state of the wireless control module following the main control module. When the main control module receives the shutdown instruction, the main control module does not immediately send a sleep instruction to the wireless control module.

[0049] In one example, when the wireless control module receives the sleep instruction sent by the main control module, it starts a timer to count the time to realize the counting of the first preset period.

[0050] Step S23, if the operating status data is received, keep running. Step S25, if the operating status data is not received, enter the sleep state.

[0051] The wireless control module determines whether to respond to the sleep instruction sent by the main control module according to whether the operating status data is received. If the wireless control module receives the operating status data, the wireless control module does not respond to the sleep instruction and keeps running. If the wireless control module does not receive the operating status data, the wireless control module responds to the sleep instruction and enters the sleep state.

[0052] In one embodiment, as Figure 3 shown, a sleep control method for a wireless control module is provided, including the following steps:

[0053] Step S31, check whether the operating status data of the main control module is received; the operating status data is generated by the main control module when it is in the operating state and is sent through the status data thread.

[0054] Step S33: If the operation status data sent by the master control module is received, update the temporary status bit to the first status bit; if the operation status data sent by the master control module is not received, update the temporary status bit to the second status bit.

[0055] Step S35: Check the temporary status bit to determine whether the operation status data sent by the master control module is received.

[0056] Step S37: If the temporary status bit is the first status bit, keep running; if the temporary status bit is the second status bit, enter the sleep state.

[0057] It should be noted that step S31 in this embodiment is the same as step S21 in the foregoing embodiment, and will not be elaborated here.

[0058] The first status bit is used to represent that the wireless control module has received the operation status data sent by the master control module. In one example, the first status bit is represented by 1. The second status bit is used to represent that the wireless control module has not received the operation status data sent by the master control module. In one example, the second status bit is represented by 0. After each check by the wireless control module on whether the operation status data is received, the check result is temporarily stored, and then the wireless control module determines whether the operation status data is received by checking the status bit. When the wireless control module checks that the temporary status bit is the first status bit, the wireless control module does not respond to the sleep instruction and keeps running. When the wireless control module checks that the temporary status bit is the second status bit, the wireless control module responds to the sleep instruction and enters the sleep state.

[0059] To enable the wireless control module to smoothly enter the next check process. In one example, after the step of keeping running if the temporary status bit is the first status bit and entering the sleep state if the temporary status bit is the second status bit, the following step is further included: clear the temporary status bit. It should be noted that after each check process ends, the temporarily stored status bit is deleted and cleared to prepare for storing the status bit of the next time, and to avoid interference of the current status bit on the next check process.

[0060] After the master control module is in the sleep or shutdown state and the wireless control module is in the sleep state, if it is necessary to wake up the wireless control module, as Figure 4 shown, the following steps are executed:

[0061] Step S41: When in the sleep state, receive the wake-up signal.

[0062] Step S43: When responding to the wake-up signal, send a power-on signal to the master control module.

[0063] When the wireless control module is in the sleep state, after receiving the wake-up signal sent by the external controller, it sends a power-on signal to the master control module to control the master control module to power on.

[0064] The wireless control module in the electronic product checks whether it has received the operation status data, where the operation status data is generated by the main control module of the electronic product when it is in the operation state and sent through the status data thread. If the wireless control module in the electronic product receives the operation status data, it remains in operation. If the wireless control module in the electronic product does not receive the operation status data, it enters the sleep state. In the sleep control method of this application, the wireless control module determines the operation state of the main control module based on whether it has received the operation status data. If it receives the operation status data, the main control module is in the operation state. If it does not receive the operation status data, the main control module is in the sleep or shutdown state, thereby enabling the state of the wireless control module to follow the state of the main control module. When the main control module is in the operation state, the wireless control module also remains in operation. When the main control module is in the sleep or shutdown state, the wireless control module also enters the sleep state, avoiding the startup error caused by the main control module still being in operation while the wireless control module has already entered the sleep state.

[0065] It should be understood that although Figures 2 - 4 the steps in the flowchart are shown in sequence according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless there is a clear indication in this article, there is no strict order limit for the execution of these steps, and these steps can be executed in other orders. Moreover, Figures 2 - 4 at least a part of the steps in
