Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a communication method, apparatus, computer storage medium, and electronic device. Background Technology

[0002] Due to variations in their internal voltage regulation modules, a certain percentage of existing electronic tags have a sensing distance shorter than designed. This can cause startup failures when attempting to initiate communication between the tag and reader using conventional methods. For example, if the design requires the tag and reader to detect each other at a distance of 19mm, placing a tag with a sensing distance of only 15mm at 19mm will fail because the tag itself lacks sufficient power to power the upper module and transmit data. This results in data transmission failure between the tag and reader.

[0003] There is currently no effective solution to the problem of data transmission between electronic tags and card readers when the sensing distance of the electronic tag is shorter than the design requirement. Summary of the Invention

[0004] This application provides a communication method, apparatus, computer storage medium, and electronic device to solve the problem in the related art where it is difficult to transmit data between the electronic tag and the card reader when the sensing distance of the electronic tag is shorter than the design required sensing distance.

[0005] According to one aspect of this application, a communication method is provided. The method includes: controlling a second wireless module to send a preset number of low-power commands to a first wireless module, wherein the second wireless module is disposed on the main body of a target device, and the first wireless module is disposed on the cover of the target device; determining whether the second wireless module receives a preset number of target data returned by the first wireless module, wherein the first wireless module returns target data each time it receives a low-power command; and, upon receiving the preset number of target data returned by the first wireless module, controlling the second wireless module to communicate with the first wireless module by sending a dynamic power consumption command, wherein the current of the dynamic power consumption command is greater than the current of the low-power command. This embodiment achieves the effect of normal data transmission between the two wireless modules even when the sensing distance between them is short by controlling the second wireless module to start the first wireless module by sending a low-power command, and then controlling the second wireless module to communicate with the first wireless module by sending a dynamic power consumption command after the first wireless module is started.

[0006] Optionally, determining whether the second wireless module has received the target data returned by the first wireless module a preset number of times includes: after each low-power command sent by the second wireless module, determining whether the second wireless module has received the target data returned by the first wireless module; if the second wireless module has received the target data returned by the first wireless module, controlling the target counter to increment by one, wherein the target counter is cleared before the second wireless module sends the low-power command for the first time; after the second wireless module sends the last low-power command to the first wireless module, determining whether the counter count has reached the preset number, wherein sending the last low-power command refers to the last low-power command among the preset number of low-power commands sent; if the counter count has reached the preset number, determining that the second wireless module has received the target data returned by the first wireless module a preset number of times; if the counter count has not reached the preset number, determining that the second wireless module has not received the target data returned by the first wireless module a preset number of times. In this embodiment, after each low-power command sent by the second wireless module, it determines whether the second wireless module has received the target data returned by the first wireless module, and combines this with the counter to count the successful transmission of the low-power command, thereby obtaining the result of whether the second wireless module has received the target data returned by the first wireless module a preset number of times.

[0007] Optionally, after determining whether the second wireless module has received the target data returned by the first wireless module a preset number of times, the method further includes: if the second wireless module receives less than the preset number of target data returned by the first wireless module, issuing an alarm message, wherein the alarm message is used to indicate that a communication connection has not been established between the first and second wireless modules. This embodiment issues an alarm when the first wireless module fails to start, preventing the target device from using a first wireless module that cannot start, thus avoiding abnormal situations during subsequent operation.

[0008] Optionally, the current range of the low-power command is between 0 and 8 μA. This embodiment transmits low-power commands with lower current, allowing for a longer transmission distance, which facilitates the first wireless module receiving the command and starting up.

[0009] Optionally, the current of the dynamic power consumption command is determined by the resistance value of the first wireless module and the resistance value of the temperature measurement module connected to the first wireless module.

In this embodiment, sending dynamic power consumption commands after the first wireless module has started normally ensures the data transmission quality between the first and second wireless modules.

[0011] Optionally, after controlling the second wireless module to communicate with the first wireless module by sending dynamic power consumption commands, the method further includes: determining the state of the cover of the target device based on the target data transmitted by the second wireless module and the first wireless module. This embodiment determines the state of the cover of the target device by transmitting target data, thereby enabling convenient determination of the cover's state without needing to set a power supply to the cover.

[0014] According to another aspect of the present invention, an electronic device is also provided, comprising a processor and a memory; the memory stores computer-readable instructions, and the processor is configured to execute the computer-readable instructions, wherein the computer-readable instructions execute a communication method when executed.

[0015] This application employs the following steps: controlling a second wireless module to send a preset number of low-power commands to a first wireless module, wherein the second wireless module is disposed on the main body of the target device, and the first wireless module is disposed on the cover of the target device; determining whether the second wireless module has received the preset number of target data returned by the first wireless module, wherein the first wireless module returns target data each time it receives a low-power command; when the second wireless module receives the preset number of target data returned by the first wireless module, controlling the second wireless module to communicate with the first wireless module by sending a dynamic power consumption command, wherein the current of the dynamic power consumption command is greater than the current of the low-power command, thus solving the problem in related technologies where data transmission between the electronic tag and the card reader is difficult when the sensing distance of the electronic tag is shorter than the design required sensing distance.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0024] According to embodiments of this application, a communication system is provided. Figure 1 This is a flowchart of a communication system according to an embodiment of this application. For example... Figure 1 As shown, the system includes:

[0025] Temperature sensor 101 is installed on the cover of the target device. Specifically, temperature sensor 101 can be an NTC (Negative Temperature Coefficient) sensor, and the target device can be a rice cooker. First wireless module 102 is installed on the cover of the target device and connected to temperature sensor 101. First wireless module 102 can be an electronic tag. First wireless module 102 and temperature sensor 101 constitute a wireless temperature measurement module to collect the temperature of the cover of the target device.

[0026] The second wireless module 103 is installed on the main body of the target device and transmits data with the first wireless module 102 wirelessly. The second wireless module 103 can be a card reader. The second wireless module 103 supplies power to the first wireless module 102 and receives temperature data sent back by the first wireless module 102. The control module 104 is connected to the second wireless module 103, controls the second wireless module 103 to supply power to the first wireless module 102, and receives temperature data sent by the second wireless module 103.

[0027] According to an embodiment of this application, a communication method is provided.

[0028] Figure 2 This is a flowchart of a communication method according to an embodiment of this application, applied in the aforementioned communication system. For example... Figure 2 As shown, the method includes the following steps:

[0029] Step S202: Control the second wireless module to send a preset number of low-power commands to the first wireless module, wherein the second wireless module is disposed on the main body of the target device and the first wireless module is disposed on the cover of the target device.

[0030] Specifically, the target device can be a rice cooker, the first wireless module can be an electronic tag set on the lid of the rice cooker, the second wireless module can be a card reader set on the main body of the rice cooker, a temperature sensor can be set on the lid of the rice cooker, the electronic tag is connected to the temperature sensor to transmit the data collected by the temperature sensor to the second wireless module, and the second wireless module can be connected to a controller.

[0031] It should be noted that due to variations in the internal voltage regulator chip during mass production of the first wireless module, a certain percentage of the first wireless modules will have a shorter sensing distance than designed. For example, if the design requires a sensing distance of 19mm for the first wireless module, it can sense commands transmitted by the second wireless module. Since the first wireless module is a passive module and requires power from the second wireless module, if the sensing distance of the first wireless module is only 15mm, when it senses the command transmitted by the second wireless module at a distance of 19mm, it will lack power upon initial startup. If the second wireless module uses dynamic power mode to send commands, the power received by the first module at 19mm will be too weak to start the first module and transmit data.

[0032] Therefore, in this embodiment, the controller controls the second wireless module to send a preset number of low-power commands, so that the first wireless module can receive enough energy to start up. Specifically, the preset number of times can be 3. When the communication system is powered on and starts working, the second wireless module sends 3 low-power commands to the first module.

[0033] It should be noted that the command can be a high-level signal or a low-level signal. The low-power command uses less current to send the command, allowing for a longer transmission distance. Optionally, in the communication method provided in this application embodiment, the current range of the low-power command is between 0 and 8 μA.

[0034] Step S204: Determine whether the second wireless module has received the target data returned by the first wireless module a preset number of times, wherein the first wireless module returns the target data each time it receives a low-power command.

[0035] Specifically, if the first wireless module can receive a low-power command, it will transmit target data back, which can be temperature data collected by a temperature sensor on the cover of the target device.

[0036] Step S206: When the second wireless module receives the target data of a preset number of times transmitted back by the first wireless module, the second wireless module is controlled to communicate with the first wireless module by sending a dynamic power consumption command, wherein the current of the dynamic power consumption command is greater than the current of the low power consumption command.

[0037] Specifically, if the second wireless module receives the target data a preset number of times from the first wireless module, it means that the first wireless module can receive the low-power command and transmit the target data each time. This indicates that the first wireless module can start normally, and the energy received plus its own energy is sufficient for continuous operation. Therefore, the controller switches the operation between the two modules from low-power mode to dynamic power mode, that is, it controls the second wireless module to communicate with the first wireless module by sending dynamic power commands. It should be noted that the current of the dynamic power command is greater than the current of the low-power command to ensure the quality of data transmission.

[0038] Optionally, in the communication method provided in the embodiments of this application, the current of the dynamic power consumption command is determined by the resistance value of the first wireless module and the resistance value of the temperature measurement module connected to the first wireless module.

[0039] It should be noted that the current of the dynamic power consumption command is related to the hardware settings of the communication system. When the temperature sensor is an NTC sensor, the current of the dynamic power consumption command is I = 1.2V / (R1 + R2 + R...). NTC ), where R1 and R2 are resistors in the first wireless module. If the resistance of R1 and R2 is 20KΩ and the resistance of the NTC sensor at room temperature is 80K, then I = 1.2V / 20K + 20K + 80K = 10uA.

[0040] The communication method provided in this application embodiment controls a second wireless module to send a preset number of low-power commands to a first wireless module. The second wireless module is disposed on the main body of the target device, and the first wireless module is disposed on the cover of the target device. The method determines whether the second wireless module has received the preset number of target data returned by the first wireless module. The first wireless module returns target data each time it receives a low-power command. When the second wireless module receives the preset number of target data returned by the first wireless module, it controls the second wireless module to communicate with the first wireless module by sending a dynamic power consumption command. The current of the dynamic power consumption command is greater than the current of the low-power command, solving the problem in related technologies where data transmission between the electronic tag and the reader is difficult when the sensing distance of the electronic tag is shorter than the designed sensing distance. By controlling the second wireless module to start the first wireless module by sending low-power commands, and then controlling the second wireless module to communicate with the first wireless module by sending dynamic power consumption commands, the method achieves the effect of normal data transmission between the two wireless modules even when the sensing distance between them is short.

[0041] Optionally, in the communication method provided in this application embodiment, determining whether the second wireless module has received the target data returned by the first wireless module a preset number of times includes: after the second wireless module sends a low-power command each time, determining whether the second wireless module has received the target data returned by the first wireless module; if the second wireless module has received the target data returned by the first wireless module, controlling the target counter to increment by one, wherein the target counter is cleared before the second wireless module sends the low-power command for the first time; after the second wireless module sends the last low-power command to the first wireless module, determining whether the counter count has reached a preset number of times, wherein sending the last low-power command refers to the last low-power command among the low-power commands sent a preset number of times; if the counter count has reached the preset number of times, determining that the second wireless module has received the target data returned by the first wireless module a preset number of times; if the counter count has not reached the preset number of times, determining that the second wireless module has not received the target data returned by the first wireless module a preset number of times.

[0042] For example, with a preset number of attempts (3), after the second wireless module sends a low-power command for the first time, if the first wireless module receives the low-power command from the second wireless module, it sends the target data back to the second wireless module. If it does not receive the low-power command, it waits for the next command. It checks whether the second wireless module receives the target data sent back by the first wireless module. If it does, the counter is incremented by 1; otherwise, the second wireless module sends the low-power command a second and third time. After three low-power commands are sent, the counter's count is checked to determine if the second wireless module has successfully sent the command three times. If so, the upper module has started successfully; otherwise, the start-up has failed.

[0043] Optionally, in the communication method provided in the embodiments of this application, after determining whether the second wireless module has received the target data returned by the first wireless module a preset number of times, the method further includes: if the second wireless module receives less than the preset number of target data returned by the first wireless module, issuing an alarm message, wherein the alarm message is used to indicate that no communication connection has been established between the first wireless module and the second wireless module.

[0044] For example, if the second wireless module fails to receive the target data returned by the first wireless module after a preset number of attempts (3 times), or receives it only once or twice, it indicates that the wireless communication between the second and first wireless modules is unreachable or unstable. In other words, the first wireless module has not started successfully, and no communication connection has been established between the first and second wireless modules. The controller will then issue an alarm message to prompt the first wireless module on the target device to be repaired or replaced.

[0045] Optionally, in the communication method provided in this application embodiment, controlling the second wireless module to communicate with the first wireless module by sending a dynamic power consumption command includes: controlling the second wireless module to send a dynamic power consumption command to the first wireless module; and controlling the second wireless module to receive the target data returned by the first wireless module.

[0046] That is, after the first wireless module is started, the energy received plus its own energy is sufficient for the first wireless module to work normally and continuously. In order to ensure the quality of data transmission, the second wireless module communicates with the first wireless module by controlling the dynamic power consumption, sending dynamic power consumption instructions to the first wireless module, and receiving the target data returned by the first wireless module.

[0047] Optionally, in the communication method provided in the embodiments of this application, after controlling the second wireless module to communicate with the first wireless module by sending dynamic power consumption instructions, the method further includes: determining the state of the cover of the target device based on the transmission of target data between the second wireless module and the first wireless module.

[0048] For example, if the second wireless module receives the target data transmitted by the first wireless module more than the set number of times within a preset time period, it indicates that the distance between the first and second wireless modules is close and the cover of the target device is closed. If the number of times the second wireless module receives the target data transmitted by the first wireless module is less than or equal to the set number of times, it indicates that the distance between the first and second wireless modules is far and the cover of the target device is open.

[0049] Figure 3 This is a flowchart of an optional communication method according to an embodiment of this application, applied in the aforementioned communication system. For example... Figure 3 As shown, the method includes the following steps:

[0050] First, the system powers on and starts working, with the lower module sending three low-power commands to the upper module.

[0051] Secondly, it determines whether the upper module has received the low-power instruction from the lower module. If it has, it sends the data back to the upper module. If it has not received the instruction, it waits for the next instruction.

[0052] Furthermore, it determines whether the lower module has received the data information returned by the upper module. If it has, the count of the successful transmission instruction is incremented by 1. If it has not received, it returns to the first step to send the low-power instruction a second and a third time.

[0053] Finally, after sending three low-power commands, it is checked whether the number of successful commands sent equals three. If yes, the module starts successfully, and subsequent sending of dynamic power commands will proceed normally. If not, the module fails to start, and the system reports an error.

[0054] This embodiment adjusts the startup mode of the wireless module and the way the module transmits energy by software. It starts in low-power mode first, and after the modules have worked stably for 3 times, it switches to dynamic power mode. This allows modules with short sensing distances to work normally at the designed distance, greatly reducing the cost of replacing or repairing modules with short sensing distances.

[0055] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0056] This application also provides a communication device. It should be noted that the communication device of this application can be used to execute the communication method provided in this application. The communication device provided in this application is described below.

[0057] Figure 4This is a schematic diagram of a communication device according to an embodiment of this application. Figure 4 As shown, the device includes: a first control unit 10, a judgment unit 20, and a second control unit 30.

[0058] Specifically, the first control unit 10 is used to control the second wireless module to send a preset number of low-power commands to the first wireless module, wherein the second wireless module is disposed on the main body of the target device and the first wireless module is disposed on the cover of the target device.

[0059] The judgment unit 20 is used to determine whether the second wireless module has received the target data returned by the first wireless module a preset number of times, wherein the first wireless module returns the target data each time it receives a low-power command.

[0060] The second control unit 30 is configured to control the second wireless module to communicate with the first wireless module by sending a dynamic power consumption command when the second wireless module receives target data of a preset number of times from the first wireless module, wherein the current of the dynamic power consumption command is greater than the current of the low power consumption command.

[0061] The communication device provided in this application embodiment controls a second wireless module to send a preset number of low-power commands to the first wireless module via a first control unit 10. The second wireless module is disposed on the main body of the target device, and the first wireless module is disposed on the cover of the target device. A judgment unit 20 determines whether the second wireless module receives the preset number of target data returned by the first wireless module. The first wireless module returns target data each time it receives a low-power command. When the second wireless module receives the preset number of target data returned by the first wireless module, the second control unit 30 controls the second wireless module to communicate with the first wireless module by sending a dynamic power consumption command. The current of the dynamic power consumption command is greater than the current of the low-power command. This solves the problem in related technologies where it is difficult for data transmission between the electronic tag and the card reader when the sensing distance of the electronic tag is shorter than the design required sensing distance. By controlling the second wireless module to start the first wireless module by sending a low-power command, and then controlling the second wireless module to communicate with the first wireless module by sending a dynamic power consumption command after starting the first wireless module, the device achieves the effect of normal data transmission between the two wireless modules even when the sensing distance between them is short.
