Description

Technical Field

[0001] This application relates to the technical field of data transmission. Specifically, this application relates to a two-way communication method, apparatus, and storage medium. Background Art

[0002] Currently, in LED lamp control and other control systems with device ends and control ends, traditional communication protocols such as the DMX512 protocol and the return-to-zero code protocol are usually adopted to transmit digital control data to achieve device control. These protocols are actually the commonly used abbreviations of a technical standard in the industry, which is a technical standard for asynchronous serial transmission of digital control data in a system of control devices and accessories. The main contents include the physical platform for implementing control data transmission, the electrical characteristics of the signal interface, the signal timing on the system data bus, the data packet format, etc.

[0003] Although these communication protocols are widely used in control systems, they have the disadvantage of only being able to transmit signals unidirectionally to control devices. Thus, the control end using these communication protocols can only transmit signals to the device end to control the operation of the device end. However, it is unable to obtain device information in a timely manner, resulting in the need for the object managing the device end to frequently go to the location where the device end is located to check the working conditions of the device end, and it is impossible to perform real-time data collection and management on the device end.

It should be noted that the following embodiments can refer to, draw on or combine with each other. For the same terms, similar features and similar implementation steps in different embodiments, they will not be described repeatedly.

[0057] The two-way communication method, device and storage medium provided by the present application are intended to solve at least one technical problem existing in the prior art.

[0058] In the embodiments of the present application, a two-way communication method is provided, as Figures 1-4 shown. The two-way communication method is used for a control end connected to at least one device end. The control system composed of the device end and the control end can be used for LED control, street lamp control, signal lamp control and the control of other objects. The control end can be a device such as a chip, a microcontroller, a microprocessor, etc. that can send a target instruction and receive the information fed back by the device end according to the target instruction.

[0059] Optionally, the number of device ends can be multiple. A single control end can be connected to multiple device ends, and a single device end can be connected to multiple control ends.

[0060] In one embodiment, the control end sends target instructions through its command port or receives the information returned by the device end. The device end receives the target instructions and the returned information through its response port. The control end and the device end form a set of RDM (The Remote Device Management Protocol) system. This system can have one or more controllers, but only one controller can be in an active state at the same time. The response port of each device end can be used for two-way communication. Specifically, as Figure 2 shown, the response port of the device end includes two address ports, ADRI and ADRO, and the command port of the control end includes two ports, DATA_A and DATA_B. The control end and the device end perform data transmission through a differential two-wire protocol. The device ends are connected in a cascaded manner. The ADRO port of one device end is connected to the ADRI port of the next device end. The ADRI port is connected to the voltage VDD and pulled up to a high level. The ADRO port is left floating (each ADRO port is default floating). When the ADRI port and the ADRO port are connected, the ADRI port is pulled down to a low level (when the device end is not processing data and the ADRI port and the ADRO port are connected, both ports are pulled down to a low level). Each device end is provided with three output ports, R, G, and B, and the display of the LED product is adjusted through this output port.

[0061] Optionally, multiple communication protocols (including but not limited to at least one of the DMX512 protocol, the return-to-zero code protocol, the two-wire protocol, the SPI (Serial Peripheral Interface) protocol, the serial port protocol, and the IIC (Inter-Integrated Circuit) protocol, which can be any communication protocol capable of information transmission between the device end and the control end) can be used for data transmission between the device end and the control end. Moreover, in order to facilitate the control end to monitor and configure the device end through the data link, the RDM can also be used to achieve data transmission between the control end and the device end.

[0062] Optionally, the device end is an LED. The control end is connected to multiple LEDs, sends target instructions to the LEDs, and displays and manages the information of the LEDs (such as the current active state, whether there is a fault, etc.) according to the information returned by the LEDs. As Figure 1 shown, the two-way communication method of the present application includes:

[0063] S101: For the target instruction to be transmitted, obtain the type information of the target instruction.

[0064] Optionally, the target instruction to be transmitted includes all instructions such as control instructions, register configuration instructions, grayscale instructions, etc. that can be used to manage LEDs or collect LED information. This type of information includes information indicating whether the target instruction is a first preset instruction or a second preset instruction. Among them, the control end can obtain the type information of the target instruction through information such as the content, format, and encoding of the target instruction.

[0065] Optionally, the target instruction to be transmitted can be generated by the control end itself or transmitted to the control end by other devices connected to the control end. After generating or receiving the target instruction, the control end can immediately transmit the target instruction to the device end, or determine the transmission time or transmission order of the target instruction according to the current state, time, and type information of the target instruction.

[0066] Optionally, the control end is provided with a command port, and the device end is provided with a response port. At least one control end communicates bidirectionally with the response port of at least one device end through the command port. And, in order to prevent interference between different control ends. Obtaining the type information of the target instruction includes: if it is determined that the current state is the active state, then obtaining the type information of the target instruction.

[0067] In one embodiment, a single device end is connected to multiple control ends. Before sending the target instruction, the control end detects whether its current state is active. If so, it is determined that the target instruction can be sent to the device end currently, and the type information of the target instruction is obtained.

[0068] Optionally, the first preset instruction includes at least one of a control instruction and a register configuration instruction. Among them, the register instruction can be used to configure the register value and register parameters of the device end (such as register parameters such as address, PWM refresh rate, current gain, low gray compensation, channel hysteresis, etc.). The second preset instruction includes a grayscale instruction, and this grayscale instruction indicates the grayscale of the device end in a certain frame. The control end sends the first preset instruction or the second preset instruction to the device end according to actual requirements and the received instruction.

[0069] S102: If the type information indicates that the target instruction is a first preset instruction, then transmit the target instruction to the target device end in a preset communication manner.

[0070] Optionally, the preset communication manner includes any one of point-to-point communication and broadcast communication. Among them, the control end and the device end perform point-to-point communication or broadcast communication based on the RDM protocol.

[0071] Optionally, if the type information indicates that the target instruction is a second preset instruction, the target instruction is transmitted to the target device end using the communication protocol corresponding to the target device end. The second preset instruction includes a grayscale instruction, and the communication protocol is any traditional communication protocol supported by the target device end, including but not limited to at least one of the DMX512 protocol, the return-to-zero code protocol, the two-wire protocol, the SPI protocol, the serial port protocol, and the IIC protocol. Among them, the second preset instruction may be a start instruction for controlling the device end to start working, a shutdown instruction for controlling the device end to stop working, and other instructions that can be transmitted through the communication protocol corresponding to the target device end.

[0072] In one embodiment, the second preset instruction is a grayscale instruction. If the control end determines that the target instruction is a grayscale instruction according to the type information of the target instruction, the target device end that receives the grayscale instruction is obtained according to the grayscale instruction or the pre-stored instruction sending information, and the grayscale instruction is sent using the communication protocol corresponding to the target device end.

[0073] Optionally, to facilitate the device end to return information, when the target instruction is a first preset instruction or a second preset instruction, the target instruction is transmitted to the target device end in a preset communication manner, including: obtaining the identification information of the target device end corresponding to the target instruction; transmitting the target instruction to the target device end at a predetermined transmission interval according to the identification information and the preset communication manner. The identification information includes the number of the target device end. Different target instructions are separated by this transmission interval, and it is convenient for the device end to return information through this transmission interval.

[0074] Optionally, the number of the target device end is a UID (unique identifier) unique identifier, and the UID of each device end is different. Among them, the identification information may also be the name, address, group, response port number of the device end, and other information that can identify the target device end.

[0075] Optionally, the control end can obtain the preset communication manner for sending the target instruction according to the preset information or the content of the target instruction, or can select one of point-to-point communication and broadcast communication for instruction sending according to information such as the sending object, sending time, sending quantity, and size of the target instruction.

[0076] In one embodiment, the target instruction is a first preset instruction, and the preset communication manner is point-to-point communication. The control end obtains the number of the target device end corresponding to the first preset instruction, and sends the number appended with the target instruction to the device end it is connected to. The device end that receives the target instruction matches the number in the target instruction with its own number. If it is determined to be consistent, it determines that itself is the target device end and executes the target instruction. If it is determined that the number is inconsistent with its own number, it does not execute the target instruction.

[0077] In another embodiment, the preset communication mode is broadcast communication, the target instruction is the first preset instruction, the control end obtains the target instruction, and determines that the target instruction needs to be sent to all device ends connected thereto. Then, the numbers corresponding to all device ends (i.e., the UIDs that can be recognized by all device ends) are obtained, the number is appended to the target instruction, and the target instruction is sent to the connected device ends. The device ends receive the target instruction and determine that they need to execute the target instruction according to the number in the target instruction.

[0078] S103: Receive the information returned by the target device end based on the target instruction.

[0079] Optionally, the first preset instruction includes any one of a control instruction and a register configuration instruction, and the returned information corresponding to the control instruction and the register configuration instruction is different. Receiving the information returned by the target device end based on the target instruction includes: if the first preset instruction is the control instruction, receiving the control parameters returned by the target device end based on the control instruction and a predetermined transmission interval. The control parameters include, but are not limited to, at least one of temperature, voltage, current, power, LED open / short circuit, device number, working time, address, and register parameters. The information included in the control parameters can be changed accordingly according to conditions such as the type of the target device end, the currently executable control operations, and actual requirements; if the first preset instruction is a register configuration instruction, receiving the register information returned by the target device end based on the register configuration instruction and a predetermined transmission interval. The register information includes at least one of the information on whether the register value is configured successfully and register parameters.

[0080] Optionally, when the first preset instruction is a control instruction, the control parameters returned by the target device end can include the control parameters of the target device end itself or the control parameters of other device ends, and the content it includes can be set according to the requirements of the target instruction.

[0081] Optionally, the device end returns information to the control end through its own response port. Receiving the information returned by the target device end based on the target instruction includes: receiving, through the command port, the information returned by the target device end through the response port in the working mode indicated by the target instruction. The working mode includes any one of a passive return mode and an active return mode. Among them, the target device end can determine the working mode used for returning information according to information such as the classification of the target instruction and the currently used working mode. Correspondingly, the target instruction may not include information indicating the working mode either.

[0082] Optionally, the device end returns information at the target instruction sending interval (i.e., the predetermined transmission interval) of the control end. The device end and the control end can also set multiple ports for data transmission, so that the device end uses different ports to receive the target instruction and return information. Furthermore, the device end can transmit data to the control end when the control end sends the target instruction.

[0083] In one embodiment, as Figure 3 shown, the first preset instruction is a control instruction. The device side includes #1, #2, and #3. The control side respectively sends target instructions for obtaining control data to #1, #2, and #3 (corresponding to #1 control data, #2 control data, and #3 control data in the figure). And when sending, each control instruction is separated and sent at a predetermined transmission interval. The device side sequentially receives the target instructions. If it is determined according to the information of the target instructions that the control parameters need to be transmitted in the passive feedback mode, then #1, #2, and #3 obtain the control parameters and sequentially generate #1 feedback data, #2 feedback data, and #3 feedback data according to the control parameters. The device side sequentially transmits the feedback data to the control side through its own response port (DINA). Among them, #1 transmits the #1 feedback data to the control side during the gap between the control side sending control instructions to #1 and #2 (i.e., the gap between #1 control data and #2 control data in the figure).

[0084] In one embodiment, as Figure 4 shown, the first preset instruction is a control instruction, and this control instruction instructs to use the active feedback mode to feedback information. After the target device side receives the control instruction, it detects whether there are continuous multi-frame control parameter abnormalities (such as temperature higher than the preset value, LED open circuit, etc.) in itself or the device corresponding to the control instruction. If so, at the end of the frame of the control data sending gray scale instruction (each gray scale instruction corresponds to one frame of gray scale data), the abnormality flag (which is a register value, default is 0) is set to 1 (other device sides will not set the abnormality flag to 1 at this time), and the control parameters are feedback during the gap when the control side sends the gray scale instruction. And after continuous multi-frame detection of normal control parameters, the abnormality flag is reset to 0. By setting the abnormality flag, it is avoided that only one device side performs information feedback at the same time. Among them, the number of frames corresponding to the continuous multi-frame is the preset frame, and the number of frames of this preset frame can be 1 frame, 2 frames, and other values, and the specific size can be defined according to actual needs.

[0085] The bidirectional communication method of the present application obtains the type information of the target instruction. After determining that the type information indicates that the target instruction is the first preset instruction, the target instruction is transmitted in a point-to-point communication or broadcast communication manner and the information feedback by the target device side is received. The embodiment of the present application can, when the target instruction is the first preset instruction, send the target instruction by using a preset communication method and correspondingly implement the reception of the feedback information, meet the bidirectional communication requirements between the control side and the device side, and facilitate data collection and management of the device side in a timely manner.

[0089] Optionally, it further includes that if the type information indicates that the target instruction is a second preset instruction, the target instruction is transmitted to the target device terminal by using the communication protocol corresponding to the target device terminal; the second preset instruction includes a gray scale instruction, and the communication protocol can be any communication protocol that can be used for information transmission between the device terminal and the control terminal, including but not limited to at least one of the DMX512 protocol, the return-to-zero code protocol, the two-wire protocol, the SPI protocol, the serial port protocol, and the IIC protocol. Among them, the communication protocol can be selected according to the protocol compatibility information of the control terminal and the target device terminal.

The device sides are connected in a cascaded manner. The ADRO port of one device side is connected to the ADRI port of the next device side. The ADRI port is connected to the voltage VDD and pulled up to the high level. The ADRO port is left floating (each ADRO port is default floating). When the ADRI port and the ADRO port are connected, the ADRI port is pulled down to the low level (when the device side is not performing data processing and the ADRI port and the ADRO port are connected, both of these ports are pulled down to the low level).

The signal output from the DATA_B port is the differential signal of the signal output from the DATA_A port, and the signal of the DINB port is the differential signal of the signal of the DINA port. Figure 2 The #1 control data, #2 control data, and #3 control data in it are control instructions sent by the control end, and the #1 feedback data, #2 feedback data, and #3 feedback data are information feedback by the device end. The control end sends a point-to-point sending template instruction based on the UID or a broadcast target instruction based on the broadcast UID. The target instruction may include the working mode used to indicate the device end to feedback information. When the target instruction is a control instruction, the format of the control instruction may be: identification code (A55A) + target device end UID + tail check code (D25A). When sending point-to-point, the UIDs corresponding to different target device ends are different. When sending broadcast, the UIDs of all control instructions are the same broadcast UID (the broadcast UID can be recognized by all device ends). In the passive feedback mode, after receiving the control instruction, the device end sequentially and passively feedbacks parameters including but not limited to the temperature, voltage, current, power, LED open circuit or short circuit, device number, etc. of the target device end itself. Among them, the passive feedback mode requires the control end to send a control instruction separately, and the device end needs to feedback information every time it receives a control instruction, which takes a long time.

[0100] In another embodiment, as Figure 4 shown, the device end uses the active feedback mode to feedback information. Figure 4One frame of grayscale data represents the grayscale instruction sent by the control terminal, and the #1 return data and #3 return data are the data returned by the device terminal. The device terminal enters the active return mode according to the control instruction sent by the control terminal. In the active return mode, the device terminal receives the grayscale instruction sent by the control terminal and detects whether its own control parameters are abnormal for multiple consecutive frames (such as high temperature, LED open circuit, etc.). When this occurs, it will set the abnormal flag (default value is 0) to 1 at the end of the frame corresponding to the grayscale data, and reset the abnormal flag to 0 after detecting that the control parameters are normal for multiple consecutive frames. The device terminal will only perform parameter return when the abnormal flag is 1, which avoids multiple parameter returns from the same device terminal and simultaneous return operations by multiple device terminals. Only the data of one device terminal is returned in each frame of grayscale data frame (the time occupied by each grayscale instruction transmission and the time interval between the start time points of the next grayscale instruction are used as one frame of grayscale data frame). The device terminal judges the level of ADRI at the end of the grayscale data frame (the device terminal takes turns to raise the level of ADRO to avoid simultaneous return by multiple terminals). If ADRI is at a high level and its own parameters are abnormal, it will return data and raise ADRO at the start of the next frame of data after the return ends; if ADRI is at a low level or its own parameters are normal, it will not perform data return and will raise ADRO at the same time.

[0101] Specifically, as Figure 4 shown, the device terminal receives a large number of grayscale data frames before returning. The first device terminal (#1) and the third device terminal (#3) detect that their own parameters are abnormal, and the second device terminal has normal own parameters. Therefore, at the end of the grayscale data frame, after the first device terminal finishes returning data, it raises the ADRI of the second device terminal. The second device terminal does not return data and raises ADRO at the same time (ADRI and ADRO are connected in sequence, and the change in the ADRO level of the previous device terminal will change the ADRI level of this device terminal. The level of ADRO of this device terminal is controlled by this device terminal itself). After the third device terminal confirms that ADRI is raised, it performs parameter return and raises ADRO at the start of the next frame of grayscale data frame after the return ends.

[0102] The two-way communication method of this application expands the two-way communication function on traditional protocols (such as DMX512 protocol, return-to-zero code protocol, two-wire protocol, SPI protocol, serial port protocol, IIC protocol, etc.), and at the same time retains its original functions (such as register configuration, chip addressing, etc.). The data that the device terminal can transmit to the controller includes but is not limited to parameters such as the temperature, voltage, current, power, LED open / short circuit, device number UID, working time, address, and register parameters of the terminal itself.
