Detailed Description
Referring to fig. 1, an internet of things gateway apparatus in an embodiment includes a gateway controller 110 and a wireless module 120, where the gateway controller 110 is provided with a reset pin and a start mode configuration pin, and the wireless module 120 is connected to the reset pin and the start mode configuration pin. The wireless module 120 is configured to establish a wireless connection with the external device 200, and detect whether a configuration instruction sent by the external device 200 is received, and when receiving the configuration instruction, the wireless module 120 outputs a corresponding level signal to the reset pin and the start mode configuration pin according to the configuration instruction, so as to control the gateway controller 110 to reset and restart.
The gateway controller 110 is a core control part of the internet of things gateway device, and specifically, the gateway controller 110 may be started in various ways, such as starting from an SD Card (Secure Digital Memory Card), starting from a NAND Flash (Flash Memory), and the like; the start mode configuration pin is a pin for controlling a start mode of the gateway controller 110.
The configuration instruction is an instruction for instructing the wireless module 120 to control the gateway controller 110 to reset and restart, and is transmitted by the external device 200 in a wireless manner. Specifically, there are multiple configuration instructions, and the different configuration instructions correspond to different starting manners, that is, the wireless module 120 may control the gateway controller 110 to adopt different starting manners when performing reset and restart according to different configuration instructions.
In the internet of things gateway device, the wireless module 120 is connected to the reset pin and the start mode configuration pin of the gateway controller 110, and the wireless module 120 can control the level states of the reset pin and the start mode configuration pin according to the configuration instruction sent by the external device 200, so as to control the gateway controller 110 to reset and restart. On one hand, the wireless module 120 and the external device 200 are in wireless connection, so that the user can conveniently carry the external device 200, when the user needs to reset and restart the internet of things gateway device, the wireless control reset and restart can be realized only by sending a configuration instruction by the external device 200, the internet of things gateway device does not need to be subjected to hardware operation with great expense, and the user operation convenience is high; on the other hand, the wireless module 120 controls the level states of the reset pin and the start mode configuration pin to control the gateway controller 110 to perform reset restart, the wireless module 120 can work independently of the gateway controller 110, and the reset restart is controlled in a soft start mode without power failure, so that the internet of things gateway device can be applicable to areas which cannot be powered off, and has a wide application range and strong practicability.
For example, the internet of things gateway device is applied to smart homes, when some small faults occur at night, a user can send a configuration instruction through the external device 200 such as a mobile phone and a tablet, the wireless module 120 receives the configuration instruction and controls the gateway controller 110 to reset and restart, and the internet of things gateway device is simple, fast and high in practicability.
In one embodiment, the gateway controller 110 includes an ARM and an FPGA, both the ARM and the FPGA have a reset pin, and the ARM further has a start mode configuration pin; ARM connects FPGA, and the reset pin and the start mode configuration pin of ARM all connect wireless module 120, and the reset pin of FPGA connects wireless module 120.
The ARM is used as a master device, the FPGA is used as a slave device, and the FPGA is equivalent to a peripheral device with reconfigurable characteristics of the ARM. The gateway controller 110 with the master-slave structure formed by the ARM and the FPGA has strong functionality. Specifically, the ARM and the FPGA are connected through a bus.
Alternatively, the gateway controller 110 may employ a separate chip with ARM and FPGA, such as ZYNQ 7000 series chip, Straitx 10 series chip; gateway controller 110 may also be in the form of a combination of two chips, ARM and FPGA. Referring to fig. 2, which is a schematic structural diagram of the gateway device of the internet of things in an embodiment, an ARM and an FPGA are embedded in the gateway controller 110, and a reset pin RST and a BOOT mode configuration pin BOOT of the gateway controller 110 are connected to a GPIO pin of the wireless module 120.
In one embodiment, the wireless module 120 is a bluetooth low energy module.
On one hand, by adopting the low-power-consumption Bluetooth module, the external device 200 only needs to start the Bluetooth function without networking, thereby improving the convenience of wireless operation reset and restart. BLE (Bluetooth Low Energy) technology, on the other hand, is a Low-cost, short-range, interoperable wireless technology operating in the unlicensed ISM radio frequency band of 2.4 GHz. BLE is designed as ULP (Ultra-Low Power) wireless technology from the beginning, and the ULP performance of the BLE is achieved by utilizing three characteristics of maximum intelligent means for reducing Power consumption, maximum standby time, fast connection and Low peak value transmitting/receiving Power consumption. While BLE technology employs a variable connection time interval, this interval may vary from milliseconds to seconds depending on the particular application. In addition, because BLE technology employs a very fast connection mode, it can be in a "non-connected" state (energy saving) at ordinary times, and both ends of the link only know each other, and the link is opened only when necessary, and then closed in as short a time as possible. The operating mode of BLE technology is well suited for transferring data from micro wireless sensors (exchanging data every half second) or other peripherals such as remote controls using fully asynchronous communication. These devices transmit very small amounts of data (typically a few bytes) and also transmit very small numbers of times (e.g., a few times per second to once per minute, or even less). Therefore, the low-power-consumption Bluetooth module is adopted, so that the working performance of the gateway device of the Internet of things can be improved, and the power consumption is reduced. It is understood that in other embodiments, wireless module 120 may also be other types of modules, such as a WIFI module.
Further, the bluetooth low energy module has two channel types: broadcast channel 3, data channel 37, total 40 channels. Because the Bluetooth and the WiFi work in the frequency band of 2.4GHz and mutual influence is possibly generated in the same use environment, the low-power-consumption Bluetooth makes system compatibility consideration, the working channel of the WiFi is avoided as much as possible when the channel list of the low-power-consumption Bluetooth module is designed, 3 broadcast channels of the low-power-consumption Bluetooth module are all outside the WiFi channel list, 9 data channels are still outside the WiFi channel except the overlapped data channel part, the reliability of the low-power-consumption Bluetooth module and the compatibility with the WiFi system are ensured, and the anti-interference characteristic in application is enhanced.
In an embodiment, the internet of things gateway device further includes any one of a WiFi module, a Zigbee module, and a GSM module, and the WiFi module, the Zigbee module, and the GSM module are in communication connection with the gateway controller 110.
The WiFi module, the Zigbee module, and the GSM module are equivalent to a data transmission channel of the gateway controller 110, and are used to connect with the gateway controller 110 to implement different functions, thereby improving the functional diversity of the internet of things gateway device. For example, when the gateway controller 110 is connected through a WiFi module, the gateway device of the internet of things is configured as a router to provide external network connection or other data transmission; if the Zigbee module is connected to the gateway controller 110, the gateway device of the internet of things is configured as a coordinator to receive data sent by other Zigbee; the gateway controller 110 is connected through the GSM module, and the gateway device of the internet of things is configured as a small-sized mobile phone base station. It is understood that in other embodiments, the internet of things gateway apparatus may further include other functional modules to implement other functions.
Specifically, the WIFI module and the Zigbee module are connected to the gateway controller 110 through a USB interface. Further, the WiFi module, the Zigbee module, and the GSM module are all connected to the ARM of the gateway controller 110.
In an embodiment, the internet of things gateway device further includes a mobile terminal, and the mobile terminal is wirelessly connected to the wireless module 120 and configured to send a configuration instruction to the wireless module 120. The mobile terminal is convenient for a user to carry, and the convenience of wireless control reset and restart is improved.
In one embodiment, the wireless module 120 establishes a wireless connection with the external device 200, including: the wireless module 120 sends a broadcast signal after being powered on, detects whether a connection request sent by the external device 200 according to the broadcast signal is received, and if so, establishes a wireless connection with the external device 200 according to the connection request.
The wireless module 120 transmits a broadcast signal so that the external device 200 can search for the wireless module 120 according to the broadcast signal to transmit a connection request to the wireless module 120. For example, the bluetooth low energy module transmits a broadcast signal after being powered on, and the user can search for the bluetooth low energy module by using the external device 200 to perform bluetooth search within a bluetooth searchable range.
In one embodiment, before the wireless module 120 establishes the wireless connection with the external device 200 according to the connection request, it is further configured to control the gateway controller 110 to be in a standby state or an initial startup state. Gateway controller 110 is initialized by controlling gateway controller 110 to be in a standby state or an initialization state.
The to-be-started state refers to a preparation state that is not yet started, and corresponds to a state to be started after the gateway controller 110 is powered on; the initialization start state refers to a state of performing initialization, configuration of adding a start mode, and starting, and corresponds to starting after the gateway controller 110 is powered on. Optionally, the wireless module 120 specifically controls which state the gateway controller 110 is, and is set by actual needs. For example, when the gateway controller 110 needs to be powered on and then does not work, and needs to be restarted, the gateway controller is initialized to a state to be started through the wireless module 120; if it is desired that the gateway controller 110 can begin operating upon power up, the gateway controller is initialized to an initialization start state by the wireless module 120.
Specifically, the wireless module 120 may set the gateway controller 110 to a standby state or to initialize a startup state by controlling the level states of the reset pin and the startup mode configuration pin. For example, when the wireless module 120 does not configure the start mode configuration pin during initialization, the gateway controller 110 enters a state to be started; if the wireless module 120 stores an initialization start-up mode in advance, the wireless module 120 outputs a level signal corresponding to the initialization start-up mode to the start-up mode configuration pin for configuration during initialization, and the gateway controller 110 enters the initialization start-up state and starts up in the initialization start-up mode.
Further, the wireless module 120 and the gateway controller 110 are powered by the same power supply device, and the gateway controller 110 is powered on while the wireless module 120 is powered on; the wireless module 120 may control the gateway controller 110 to be in a standby state or an initialization state while transmitting a broadcast signal after power-on.
In one embodiment, the plurality of start mode configuration pins are provided, and the wireless module 120 outputs corresponding level signals to the reset pin and the start mode configuration pin according to the configuration instruction to control the gateway controller 110 to reset and restart, including: the wireless module 120 outputs a reset level to the reset pin; the wireless module 120 obtains the start configuration information corresponding to the configuration instruction, and outputs a corresponding level signal to each start mode configuration pin according to the configuration information, so that the gateway controller 110 starts according to the start mode corresponding to the start configuration information.
The wireless module 120 outputs a reset level to the reset pin, thereby controlling the gateway controller 110 to reset; the wireless module 120 outputs a level signal to the start mode configuration pin, thereby controlling the gateway controller 110 to restart. There are various combinations of the level states of the plurality of start mode configuration pins. Through setting up a plurality of start mode configuration pins, support to set up multiple start-up mode, improve the functional diversity.
Alternatively, a low level may be used as the reset level, and a high level may be used as the reset level. Specifically, the wireless module 120 may pre-store a corresponding relationship table between the configuration instruction and the start configuration information, and obtain the corresponding configuration information by looking up the table after analyzing the configuration instruction; the configuration information is used to indicate the level state of each boot mode configuration pin, for example, there are 4 boot mode configuration pins, the configuration information includes 1000, 1010, 1011, etc., the boot mode corresponding to 1000 is boot from SD card, and the boot mode corresponding to 1010 is boot from NAND Flash.
In an embodiment, the wireless module 120 outputs a corresponding level signal to the reset pin and the start mode configuration pin according to the configuration instruction, controls the gateway controller 110 to reset and restart, and is further configured to detect whether to disconnect from the external device 200, and the wireless module 120 repeatedly sends the broadcast signal when disconnecting from the external device 200; while maintaining the connection with the external device 200, the wireless module 120 repeatedly detects whether or not a configuration instruction transmitted from the external device 200 is received. In this way, the wireless module 120 can automatically detect the wireless connection state with the external device 200, and when the wireless module is disconnected, the broadcast signal is continuously transmitted so that the external device 200 is connected again, which is convenient for use.
In an embodiment, the wireless module 120 is further configured to send a prompt message to the receiving end when receiving an invalid instruction after detecting whether the configuration instruction sent by the external device 200 is received. The prompt is used to indicate that the wireless module 120 is not working properly when receiving the invalid command. In this way, the wireless module 120 can be queried for proper operation at the time of testing or maintenance, so that the user can know.
The receiving end refers to a computer connected to the wireless module 120 through a serial port of the wireless module 120. It is understood that in other embodiments, wireless module 120 may also send a hint information to gateway controller 110.
