Description
Technical Field
The utility model relates to the technical field of wireless communication, in particular to a Bluetooth wireless communication system and intelligent equipment.
Background
After the intelligent device is researched and developed or measured, the intelligent device needs to be debugged in order to solve the problems existing in the intelligent device. The traditional intelligent device debugging method is to connect a debugging host and the debugged intelligent device in a wired mode. The wired connection mode requires a wired debugging interface on the debugged equipment, and leads out a special connection line for debugging, generally a serial port line. However, some intelligent devices are limited by use conditions or use environments, and the intelligent devices need to be realized by a wireless debugging method.
Because bluetooth wireless communication does not need the internet, bluetooth module can adapt to multiple service environment with the intelligent device. When wireless debugging is implemented on the intelligent equipment, an operator can realize wireless communication with a Bluetooth module in the intelligent equipment through a computer with a Bluetooth communication function, so that the intelligent equipment is prevented from being debugged through a communication cable.
The existing Bluetooth wireless communication technical scheme has single function or unstable data transmission. When the intelligent device is debugged through the external device with the Bluetooth communication function, the external device can transmit a debugging signal to the Bluetooth module in the intelligent device, and the asynchronous communication port of the Bluetooth module in the intelligent device transmits the debugging signal to the main control end of the intelligent device, so that the purpose of debugging the intelligent device is realized. However, in the process that the intelligent device is debugged for a long time, the asynchronous communication port of the Bluetooth module inside the intelligent device is occupied, so that the intelligent device cannot transmit other common data to the outside by means of the Bluetooth module, and the Bluetooth module can only realize the debugging function. If the intelligent device is required to be capable of transmitting common data with the outside, only one Bluetooth module can be arranged in the intelligent device, wherein one Bluetooth module realizes a wireless debugging function, and the other Bluetooth module realizes a data transmission function. Therefore, the external equipment needs to control the two Bluetooth modules simultaneously, which brings inconvenience to the debugging of the intelligent equipment. In addition, due to the fact that two Bluetooth modules exist at the same time, the two Bluetooth modules can interfere with each other when transmitting signals at the same time, and transmission of signal data is affected.

As shown in fig. 1-3, a wireless communication smart device according to a preferred embodiment of the present utility model will be described in detail below, wherein the wireless communication smart device includes a device body, and the device body includes a master controller 900 and a bluetooth wireless communication system, and the bluetooth wireless communication system is used for wirelessly connecting the master controller 900 and an external wireless communication unit 800. The main controller 900 has a debug channel 901 and a data transmission channel 902, and the bluetooth wireless communication system is used for switching the connection state between the debug channel 901 or the data transmission channel 902 and the wireless communication component 800, so that the external wireless communication component 800 can debug the main controller 900 or transmit data to the main controller 900, and therefore, the debug data and the common data of the main controller 900 in the debug process are distinguished, so that the external wireless communication component 800 can normally transmit data with the wireless communication intelligent device, and can normally debug the wireless communication intelligent device.
The device body further includes at least one input unit 910, at least one output unit 920, at least one storage unit 930, and at least one internet of things module 940, where the input unit 910, the output unit 920, the storage unit 930, and the internet of things module 940 are all electrically connected to the main controller 900, and are capable of transmitting data to the main controller 900 or receiving data transmitted from the main controller 900. When the wireless communication intelligent device is debugged by the external wireless communication part 800, the debugging data in the main controller 900 is transmitted to the wireless communication part 800 through the debugging channel 901. When the normal data needs to be transmitted, the master controller 900 can use the data transmission channel 902 to transmit the normal data with the wireless communication unit 800.
The bluetooth wireless communication system comprises a bluetooth module 10 and a channel switching module 20.
The bluetooth module 10 has an asynchronous serial port channel 101 and a judging terminal 102, wherein the judging terminal 102 is electrically connected with the wireless communication unit 800, and is used for judging the type of data transmitted to the asynchronous serial port channel 101 by the wireless communication unit 800. For example, when the wireless communication unit 800 transmits an electrical signal to the determining terminal 102, the determining terminal 102 generates a control electrical signal according to the type of the electrical signal. As will be appreciated by those skilled in the art, when the determining terminal 102 determines that the electrical signal transmitted from the wireless communication unit 800 changes, the determining terminal 102 generates a different control electrical signal.
The channel switching module 20 is simultaneously in communication connection with the asynchronous serial port channel 101, the debug channel 901 and the data transmission channel 902, and the channel switching module 20 is electrically connected with the judgment terminal 102 and is configured to receive the control electrical signal generated by the judgment terminal 102. The channel switching module 20 makes the asynchronous serial port channel 101 and the debug channel 901 be in communication connection according to the change of the control electrical signal, or switches to the asynchronous serial port channel 101 and the data transmission channel 902 to be in communication connection.
Specifically, when the wireless communication unit 800 transmits a data to the asynchronous serial port channel 101, the determining end 102 determines the data type, and then sends the data to the debug channel 901 or the data transmission channel 902 through the asynchronous serial port channel 101, and finally transmits the data to the main controller 900. Similarly, the master 900 can also transmit data to the asynchronous serial port channel 101 via the debug channel 901 or the data transmission channel 902, and then transmit the data to the wireless communication unit 800.
For example, at the determining end 102 determines that the data type is debug data, the determining end 102 sends a high-level control electrical signal to the channel switching module 20, and the channel switching module 20 can make the asynchronous serial port channel 101 be communicatively connected with the debug channel 901, at this time, the master controller 900 is communicatively connected with the bluetooth module 10 through the debug channel 901, and at the same time, the wireless communication channel 800 can implement wireless debug for the master controller 900. If the judging end 102 judges that the data type is changed to the normal data, the judging end 102 sends a low-level control electric signal to the channel switching module 20, the channel switching module 20 can disconnect the asynchronous serial port channel 101 from the debug channel 901 and enable the asynchronous serial port channel 101 to be in communication connection with the data transmission channel 902, at this time, the master controller 900 is in communication connection with the bluetooth module 10 through the data transmission channel 902, and the master controller 900 can transmit the normal data to the wireless communication component 800, so that the problem that the asynchronous serial port channel 101 is occupied by the debug channel 901 for a long time can be solved, and normal data of the master controller 900 can be ensured to be normally transmitted to the bluetooth module 10. In addition, the wireless communication channel 800 is separated from the debug data of the master 900 and the normal data interacted with the master 900, so that the data is not disturbed in the transmission process.
Specifically, the channel switching module 20 has a selection terminal 201, a debug terminal 202, a data transmission terminal 203, and a control terminal 204, wherein the selection terminal 201 is electrically connected to the debug terminal 202 or the data transmission terminal 203. The selection terminal 201 is electrically connected to the asynchronous serial port channel 101, wherein the debug terminal 202 is electrically connected to the debug channel 901, and wherein the data transfer terminal 203 is electrically connected to the data transfer channel 902. The judging end 102 is electrically connected with the control end 204, the control end 204 is electrically connected with the selecting end 201, the control end 204 switches the electrical connection state of the selecting end 201 and the debugging end 202 or the data transmission end 203 according to the control electrical signal output by the judging end 102, so that the asynchronous serial port channel 101 is conducted with the data transmission channel 902, or the asynchronous serial port channel 101 is conducted with the data transmission channel 902, so that the common data output by the main controller 900 and the debugging data output by the main controller 900 are mutually independent in the transmission process, and the main controller 900 is not interfered with the common data transmission process in the debugging process.
As shown in fig. 2, further specifically, the channel switching module 20 is implemented as a two-way single pole double throw analog switch. Conduction of the asynchronous serial port channel 101 and the data transmission channel 902 is defined as a normally closed state of the two-way single-pole double-throw analog switch, and conduction of the asynchronous serial port channel 101 and the debug channel 901 is defined as a normally open state of the two-way single-pole double-throw analog switch.
The asynchronous serial port channel 101, the debug channel 901 and the data transmission channel 902 all have a transmitting end and a receiving end. The number of the selection terminal 201, the debug terminal 202, and the data transmission terminal 203 is two, and is electrically connected to the transmission terminal and the reception terminal of the asynchronous serial port channel 101, the debug channel 901, and the data transmission channel 902, respectively.
The selection terminal 201 includes a first selection terminal 2011 and a second selection terminal 2012, and the first selection terminal 2011 and the second selection terminal 2012 are correspondingly connected to the transmitting terminal and the receiving terminal of the asynchronous serial port channel 101.
The debug terminal 202 includes a first debug terminal 2021 and a second debug terminal 2022, and the first debug terminal 2021 and the second debug terminal 2022 are electrically connected to the transmitting terminal and the receiving terminal of the debug channel 901, respectively.
The data transmission end 203 includes a first data transmission end 2031 and a second data transmission end 2032, where the first data transmission end 2031 and the second data transmission end 2032 are correspondingly connected to the transmitting end and the receiving end of the data transmission channel 902.
The two-way single-pole double-throw analog switch has two selection blades, and the control end 204 is configured to electrically connect one of the judgment ends 102 and the two selection blades, so that the connection point of the selection blades is changed according to the control electrical signal output by the judgment end 102. The selection knife is electrically connected with the data transmission end 203, and the two-way single-pole double-throw analog switch is in a normally closed state. The selection knife is electrically connected with the debugging end 202, and the two-way single-pole double-throw analog switch is in a normally open state. Further by way of example, when the determining terminal 102 receives the debug data, the determining terminal 102 outputs a high-level control electrical signal to the control terminal 204, and the control terminal 204 switches the connection position of the selecting terminal 201, and at this time, the selecting terminal 201 is electrically connected to the debug terminal 202, and the two-way single pole double throw analog switch is switched from the normally closed state to the normally open state. That is, the first selection terminal 2011 is electrically connected to the second debug terminal 2022, and the second selection terminal 2011 is electrically connected to the first debug terminal 2021. In other words, the transmitting end and the receiving end of the asynchronous serial port channel 101 are electrically connected to the receiving end and the transmitting end of the debug channel 901, respectively. Thus, the debug data of the master 900 can interact with the wireless communication channel 800 through the bluetooth module 10. If the determining terminal 102 determines that the received data type is changed to the normal data at this time, the determining terminal 102 outputs a low-level control electrical signal to the control terminal 204, the control terminal 204 switches the two-way single pole double throw analog switch from the normally open state to the normally closed state, at this time, the selecting terminal 201 is electrically connected to the data transmitting terminal, the first selecting terminal 2011 is electrically connected to the second data transmitting terminal 2032, and the second selecting terminal 2012 is electrically connected to the first data transmitting terminal 2031. In other words, the transmitting end and the receiving end of the asynchronous serial port channel 101 are electrically connected to the receiving end and the transmitting end of the data transmission channel 902, respectively. Thus, the wireless communication channel 800 can realize data transmission with the master controller 900 through the bluetooth module 10.
When an operator transmits an electrical signal to the bluetooth module 10 by using external equipment, wherein the judging end 102 judges the electrical signal, the judging end 102 correspondingly outputs the control electrical signal according to the type of the electrical signal, and then the control end 204 controls the states of the debugging channel 901 and the data transmission channel 902 to conduct the asynchronous serial port channel 101, so that the asynchronous serial port channel 101 can be switched between the data transmission channel 902 and the debugging channel 901. Thus, the wireless communication channel 800 is capable of wireless debugging or transmitting data with the master 900. It can be appreciated that, when the operator does not transmit the electrical signal to the bluetooth module 10 through the wireless communication channel 800, the bluetooth module 10 does not receive the debug electrical signal, and then the asynchronous serial port channel 101 is communicatively connected to the data transmission channel 902, and the wireless communication channel 800 is capable of transmitting data with the master controller 900; and once the bluetooth module 10 receives the debug electrical signal, the asynchronous serial port channel 101 is communicatively connected to the debug channel, and the wireless communication channel 800 is capable of debugging the master 900.
The bluetooth module 10 further includes a reset terminal 103, where the reset terminal 103 is communicatively connected to the master controller 900. When an operator transmits a reset electric signal to the bluetooth module 10 through the wireless communication channel 800, at this time, the reset terminal 103 in the bluetooth module 10 is turned on, and the reset terminal 103 can simultaneously transmit the reset electric signal to the master controller 900, so that the master controller 900 is reset and restarted. When the master controller 900 is dead or is on a card, the wireless communication channel 800 can remotely transmit the reset electrical signal to the master controller 900, so that the master controller 900 is directly reset, and the function of remotely restarting the master controller 900 is realized.
The utility model also provides a Bluetooth debugging control method, which comprises the following steps:
step S1: transmits an electrical signal to a bluetooth module 10.
Step S2: the type of the electrical signal in the step S1 is determined, and the electrical signal is switched to a debug channel 901 or a data transmission channel 902 according to the type of the electrical signal.
The bluetooth module 10 has a determining end 102, where the determining end 102 is configured to receive the electrical signal and determine a type of the electrical signal.
The wireless debugging method comprises a channel switching module 20, wherein the channel switching module 20 is simultaneously in communication connection with an asynchronous serial port channel 101, a debugging channel 901 and a data transmission channel 902. If the judging end 102 judges that the electric signal is a debug electric signal, switching to the communication connection between the asynchronous serial port channel 101 and the debug channel 901; if the electrical signal is not the debug electrical signal, the asynchronous serial port channel 101 is switched to be in communication connection with the data transmission channel 902.
More specifically, if the bluetooth module 10 determines that the electrical signal is a debug electrical signal, the bluetooth module 10 generates a high-level control electrical signal and transmits the high-level control electrical signal to the channel switching module 20, and the channel switching module 20 makes the asynchronous serial port channel 101 and the debug channel 901 in communication connection; if the bluetooth module 10 determines that the electrical signal is not a debug electrical signal, the bluetooth module 10 generates a low level control electrical signal and transmits the low level control electrical signal to the channel switching module 20, and the channel switching module 20 makes the asynchronous serial port channel 101 and the data transmission channel 902 in communication connection. Therefore, the master controller 900 can transmit or receive the debug data or the normal data to the outside through the bluetooth module 10, so as to ensure that the master controller 900 can realize wireless debug with the outside and transmit the normal data.
Regarding the improvement of software, in order to achieve the object of the present utility model, based on the bluetooth module 10 already having the headset audio transmission protocol HSP (HeadSet Profile) and the object transmission protocol OPP (Object Push Profile), a serial port protocol SPP (Serial Port Profile) and a man-machine interface protocol HID (Human Interface Profile) are added to the bluetooth module 10. The serial port protocol SPP is added to the bluetooth module 10 to enable the bluetooth module 10 to realize wireless communication with the master controller 900, so that the master controller 900 can avoid the need of wired connection with the bluetooth module 10. The man-machine interface protocol HID is added to the bluetooth module 10 to enable the bluetooth module 10 to transmit an electrical signal to the master controller 900 or the channel switching module 20, that is, the wireless communication channel 800 can transmit an electrical signal to the bluetooth module 10, and control the master controller 900 to restart or switch a channel connected with the master controller 900 by the bluetooth module 10, and the man-machine interface protocol HID can also enable the determination terminal 102 to identify a type of a debug electrical signal. Specifically, the determining terminal 102 may be implemented as a determining module.
Specifically, the internet of things module 940 may be implemented as a plurality of common commercial 4G cards, and a plurality of operators' 4G cards are simultaneously communicatively connected to the master 900. When the internet of things of the wireless communication intelligent device is disconnected, the external wireless communication unit 800 can transmit an electrical signal of a switching operator to the master controller 900 through the bluetooth module 10, and at this time, the master controller 900 can switch to a different 4G card to attempt to acquire the internet of things again.
