Specifically, the audio playing device 1 is connected to the central control device 2, and is configured to play the audio file and output a time code of the audio file to the central control device 2 in real time. According to the present invention, the audio playing device 1 may be physically connected to the central control device 2, and the physical connection is, for example, an audio line or an LTC line, and those skilled in the art will recognize that the connection mode between the audio playing device 1 and the central control device 2 is not limited to a physical connection, but may be any other connection mode, which is subject to outputting the time code of the audio file to the central control device 2. Further, the audio playing device 1 is a general audio player, such as a sound box.
Specifically, in the present invention, the time code is an encoding of a time contained in an audio file for recording a minimum unit (the minimum unit is, for example, one frame) of the audio file, and the time code may be parsed into a general physical time, for example, a few minutes and seconds.
The central control device 2 is wirelessly connected to the M wireless receiving devices through an LoRa protocol, and configured to parse the received time code, and send a first operation instruction to the M wireless receiving devices based on the parsed current playing node time, where the first operation instruction at least includes: and wireless receiving equipment identification and operation content. According to the invention, the LoRa protocol allows access of a large number of wireless devices, therefore, the LoRa protocol is adopted to be connected with the central control device 2 and the plurality of wireless receiving devices instead of Wi-Fi or Bluetooth technology, and the distance and scale requirements of practical application scenes on the system can be objectively met, in the invention, M is more than or equal to 1, preferably, the value range of M is [250, 5000 ].
In the present invention, the wireless receiving device identifier is used to uniquely identify the wireless receiving device, and may be, for example, a MAC address of the wireless receiving device. The operation content may be various, for example, the target terminal is enabled to play a few video clips, turn on or off a flash or perform a specified action, and the like, and the operation content may be set by a user as known by those skilled in the art. Further, the target terminal may be a micro-processing device or the like commonly used in the art, such as a robot, an LED display device, or the like.
According to the present invention, the central control apparatus 2 may parse the received time code based on any method existing in the art, and the present invention does not limit the parsing method of the time code. Further, the central control device 2 obtains and sends the first operation instruction to the M wireless receiving devices according to the analyzed current playing node time on the basis of the first mapping table. In a preferred embodiment of the present invention, before the audio file is played, the central control device 2 actively or passively communicates with a control server to obtain the first mapping table.
Specifically, the first mapping table may be stored in various forms, for example, a common table, a database, and the like; when a table mode is adopted, the first mapping table is a table using the current playing node time as a main key, wherein the first mapping table further comprises: wireless receiving device identification, operation content, target terminal operation execution time and other attributes. After the central control device 2 analyzes the current playing node time, based on the current playing node time and the first mapping table, the wireless receiving device identifier, the operation content, the target terminal operation execution time, and the like corresponding to the current playing node time are obtained, and then the first operation instruction is obtained.
Adaptively, in an embodiment of the present invention, the central control apparatus 2 is configured to send the first operation instruction to a total of M wireless receiving apparatuses including the wireless receiving apparatuses 301, 302, …, 303; in a preferred embodiment of the present invention, the central control device 2 is configured to continuously send the first operation instruction to a total of M wireless receiving devices including the wireless receiving devices 301, 302, …, 303L times according to a first preset frequency, where L ≧ 2, preferably, L has a value range of [2,10], for example, L may have a value of 2, 3, 4, or 5. According to the present invention, the first preset frequency may be set in a self-defined manner, so that all L transmissions of the same first operation instruction are determined as the same operation instruction by the M wireless receiving devices, for example, when the first local time and/or the target terminal operation execution time in the operation instruction are expressed in a second level, the first preset interval corresponding to the first preset frequency may be set in a millisecond level. The wireless receiving equipment can receive the first operation instruction to a great extent by continuously sending the first operation instruction for multiple times, so that the signal stability of the system is improved.
The M wireless receiving devices are used for sending a second operation instruction to a target terminal connected with the M wireless receiving devices according to the received first operation instruction so that the target terminal synchronously executes operation according to the second operation instruction; furthermore, each wireless receiving device comprises N wireless receiving units which are used for receiving the first operation instruction and run in parallel, wherein N is more than or equal to 2.

Fig. 2 is a schematic structural diagram of a wireless receiving device including two wireless receiving units in fig. 1 according to the present invention, and in fig. 2, the wireless receiving device 301 includes wireless receiving units 3011 and 3012, a processing unit 3015, wireless receiving storage units 3013 and 3014, and an instruction execution storage unit 3016, where the wireless receiving storage units 3013 and 3014 correspond to the wireless receiving units 3011 and 3012, respectively, so that the wireless receiving units 3011 and 3012 write received instructions therein. According to the present invention, the wireless receiving units 3011 and 3012 are the same and operate in parallel, and are respectively configured to receive the first operation instruction sent from the central control device 2, and by providing a plurality of wireless receiving units operating in parallel, the probability that the wireless receiving device receives the first operation instruction can be greatly increased, thereby improving the signal stability in the whole system.
For example, when receiving the first operation instruction, the wireless receiving unit 3011 first determines whether the first operation instruction is legal according to the identifier of the wireless receiving device, and if the identifier of the wireless receiving device included in the first operation instruction is different from the identifier of the wireless receiving device 2 where the wireless receiving unit 3011 is located, the first operation instruction is illegal, and at this time, the first operation instruction is discarded; otherwise, the first operation instruction is legal, and the wireless receiving unit 3011 writes the first operation instruction into a wireless receiving storage unit 3013 corresponding to the wireless receiving unit 3011. Similarly, when the wireless receiving unit 3012 receives the first operation instruction, the operation process is the same as that of the wireless receiving unit 3011, and details are not described here again.
The processing unit 3015 monitors data writing conditions of all the wireless reception storage units 3013 and 3014 in the wireless reception device 301, for example, when the processing unit 3015 monitors that data is written in the wireless reception storage unit 3013 and a command in the wireless reception storage unit 3013 is different from a command in the command execution storage unit 3016, the processing unit 3015 writes the command in the wireless reception storage unit 3013 into the command execution storage unit 3016, analyzes the command in the wireless reception storage unit 3013, and sends a second operation command to the target terminal.
According to the present invention, the wireless receiving device and the target terminal corresponding to the wireless receiving device are physically connected, and those skilled in the art can also know that the connection can be made in other ways, such as wireless connection. In the invention, the target terminal can analyze and execute the second operation instruction, and in order to accelerate the execution speed of the target terminal and improve the execution stability, the target terminal locally stores materials and the like required by executing the second operation instruction.
According to the invention, through connecting the central control device and the wireless receiving device with at least two wireless receiving units operating in parallel by using the LoRa protocol, on one hand, a large number of wireless receiving devices can be added according to the needs to meet the requirements of the practical application scene on distance and quantity, and on the other hand, a plurality of wireless receiving units operating in parallel receive the operation instructions sent by the central control device, so that the possibility that the wireless receiving device obtains the operation instructions is greatly improved, and the signal stability of the system is enhanced.
In the present invention, the first operation instruction further includes a target terminal operation execution time, a first local time of the central control device 2, and/or a current playing node time, where the first local time is the local time of the central control device 2 obtained when the central control device 2 sends the first operation instruction.
At this time, in an embodiment of the present invention, when it is monitored that data is written in any one of the wireless reception storage units, the instruction in the wireless reception storage unit is different from the instruction in the instruction execution storage unit, and a time difference between the first local time included in the instruction in the wireless reception storage unit and the first local time included in the instruction execution storage unit is greater than a time difference threshold, the processing unit is further configured to write the instruction in the wireless reception storage unit into the instruction execution storage unit, analyze the instruction in the wireless reception storage unit, and send the second operation instruction to the target terminal. According to the invention, the time difference threshold can be set in a self-defined way, and the value of the time difference threshold is a value commonly used in the field. By further judging the time difference between the first local time of the instruction in the instruction execution storage unit and the first local time of the instruction in the wireless receiving storage unit, invalid instructions which are delayed to be received due to network blockage can be obviously filtered, and the accuracy of the system is further improved.
For example, when the processing unit 3015 monitors that data is written in the wireless reception storage unit 3013, and the instruction in the wireless reception storage unit 3013 is different from the instruction in the instruction execution storage unit 3016, and the time difference between the first local time included in the instruction execution storage unit 3016 and the first local time included in the instruction in the wireless reception storage unit 3013 is greater than the time difference threshold, the processing unit 3015 writes the instruction in the wireless reception storage unit 3013 into the instruction execution storage unit 3016, analyzes the instruction in the wireless reception storage unit 3013, and sends the second operation instruction to the target terminal.
Further, the processing unit is further configured to calibrate a current local time of the wireless receiving device including the processing unit according to the parsed first local time of the instruction. By using the local time in the correct instruction to calibrate the current local time of the invalid receiving device, the time synchronism of the whole system can be promoted, and the synchronism of the execution operation of the target terminal is further improved.
In another embodiment of the present invention, each of the M wireless receiving devices includes a second mapping table, and when the central control device 2 is disconnected or down, the processing unit in the wireless receiving device may automatically send a second operation instruction to the target terminal connected to the processing unit according to the contents in the second mapping table. According to the invention, the wireless receiving device can send the second operation instruction to the target terminal based on the local time of the wireless receiving device and the content in the second mapping table.
According to the invention, the central control device is further configured to send a time synchronization instruction to a wireless receiving device wirelessly connected to the central control device according to a second preset frequency, where the time synchronization instruction at least includes a first local time of the central control device, so that the wireless receiving device calibrates its current local time when receiving the time synchronization instruction. In the invention, when a new wireless receiving device is added at any time according to the actual environment requirement, once the central control device monitors that the wireless receiving device is accessed, the central control device can send the time synchronization instruction to the newly accessed wireless receiving device, thereby accelerating the time synchronization speed of the whole system. In this case, the wireless receiving unit of the wireless receiving device or the wireless receiving device may further determine the type of the instruction before determining the validity of the instruction, and when the instruction is determined as the first operation type, the operation may be performed according to the function of the wireless receiving unit, for example, the validity of the instruction may be determined, and when the instruction is determined as the time synchronization type, the processing unit may perform the operation of calibrating the local time according to the time synchronization instruction.
