As shown in fig. 1 and fig. 2, in a first aspect of the present invention, a Tbox sleep wake-up control method is provided, which is applied to a vehicle Tbox, and includes:
s100, responding to a received sleep signal, and judging whether a first preset condition is met; if the first preset condition is met, the step S200 is executed; otherwise, entering S300;

s500: establishing data connection with a server, and judging whether a second preset condition is met; if yes, go to step S400; if not, go to step S300. Therefore, the embodiment adds the judgment condition, so that the Tbox can only be awakened through the first awakening instruction when meeting the first preset condition, establishes the data connection with the server when not meeting the first preset condition, and controls to enter the awakening state or keep the low power consumption state according to the judgment condition, thereby realizing entering different low power consumption states under different conditions, and compared with the prior art, the reliability of awakening and the timeliness of response can be effectively improved only through short message awakening.
Specifically, the Tbox, namely the Telematics Box, refers to an on-vehicle Tbox terminal, and a typical Tbox internally includes a 2G/3G/4G module, a satellite positioning module, an MCU controller, a CAN transceiver, an eSIM module and a power module, and optionally further includes an E-Call audio amplification module, a built-in speaker module, an ethernet module, a BT/Wifi module, a built-in antenna module, a 3-axis gyroscope, an RTC module, an external storage module, a BLE module, and the like. The Tbox is mainly used for collecting vehicle-related information, for example, collecting position information, attitude information and the like of a vehicle through a CAN bus, and then transmitting the information to a TSP platform through wireless communication, and meanwhile, a user CAN log in the TSP platform by using a mobile phone APP and a Web client and send an instruction to the Tbox through the TSP platform to control the vehicle, wherein the TSP platform is deployed on a server. In this embodiment, the sleep signal may be an engine stall signal of the vehicle, and when the Tbox receives the sleep signal, it is first determined whether a first preset condition is satisfied, and if the first preset condition is satisfied, the Tbox is controlled to enter a low power consumption state, and the data connection with the server is disconnected. In the embodiment, the Tbox acquires a satellite navigation message through a satellite positioning module to further acquire a current ephemeris time, the preset time period is 22:00 to 6:00, and since 22:00 to 6:00 are nights, the probability of the vehicle owner to re-use the vehicle in the time period is considered to be low, when the current ephemeris time is between 22:00 and 6:00, the Tbox is controlled to enter a sleep mode, that is, the Tbox enters a low power consumption state, only the NAD module is in a standby state, and all unnecessary peripheral modules are turned off, so that the static power consumption of the Tbox is kept to be the lowest, and in the sleep mode, the static power consumption of the Tbox is usually 1mA, wherein the NAD module is a networking module, such as a 2G/3G/4G module; meanwhile, the Tbox disconnects the data connection with the server, so that the Tbox can only be woken up by a short message sent by the server in the sleep mode. If the current ephemeris time is not between 22:00 and 6:00, a standby mode 1 is entered, and the standby mode 1 starts a timing function through the RTC module on the basis of the sleep mode, and since the static current of the RTC module is usually a few microamps, the static power consumption of the Tbox is basically the same as that of the sleep mode, and is usually 1 mA. After entering the standby mode 1, the RTC module starts timing and enters the first delay, in this embodiment, the first delay is set to 1 hour, and the specific duration of the first delay can also be determined according to actual conditions. If the Tbox receives the short message sent by the server to wake up in the first time delay, the Tbox enters a working mode, namely the Tbox enters a wake-up state, all functional modules work normally, and the consumed current is normal working current; if the Tbox does not receive the short message sent by the server within the first delay, the Tbox enters a standby mode 2 to establish data connection with the server, wherein the standby mode 2 increases the data connection function of the Tbox and the server on the basis of the standby mode 1, and the static power consumption of the Tbox is greater than that of the standby mode 1 and is usually 2-3 mA. And after entering the standby mode 2, the internal NAD module of the Tbox wakes up and is connected with the server, and meanwhile, whether a second preset condition is met is further judged, if so, the Tbox is woken up and enters a working mode, otherwise, the Tbox enters the standby mode 1, the connection with the server is disconnected, the server enters the first time delay again, and the process is repeated. The second preset condition may be a determination condition that data wakeup can be achieved through data connection with the server.
Wherein, the second preset condition comprises:
and the account corresponding to the vehicle-mounted Tbox is in a state of logging in the server, and receives a second awakening instruction in second time delay.
Specifically, after the Tbox enters the standby mode 2, the Tbox detects whether an account corresponding to the Tbox is in a login state in the server, if the account is detected to be in the login state in the server, the Tbox enters the standby mode 3, an RTC module of the Tbox starts timing, a second delay is entered, if a second wake-up instruction is received in the second delay, the Tbox enters the working mode, otherwise, the probability that the vehicle owner remotely controls the vehicle in a short time is considered to be low, the Tbox returns to the standby mode 1, the data connection with the server is disconnected, and the first delay is re-entered, wherein the second wake-up instruction is a data wake-up instruction, for example, a wake-up instruction generated by a user sending service data through a TSP platform and triggering, and the second delay may be 1 hour or determined according to actual conditions; if the account is detected not to be in the login state at the server, the Tbox returns to the standby mode 1, the data connection with the server is disconnected, and the first delay is entered again.
In this embodiment, in the standby mode 3, on the basis of the standby mode 2, a function of keeping a Tbox in long connection with the server is added, and the static power consumption of the Tbox is the same as that of the standby mode 2, and is usually 2 to 3mA, so that the Tbox enters the standby mode 3, and the data wake-up instruction is not received within the second delay, and it is checked that the account corresponding to the onboard Tbox is in a state of logging in the server, the method further includes: and sending heartbeat packets to the server at regular time in a low power consumption state so as to maintain long connection with the server. By detecting whether the user account logs in the TSP platform or not, the probability that the vehicle owner remotely issues the control instruction to the Tbox through the APP or the Web client can be judged. In this embodiment, after the user account is detected to log in the TSP platform, it is considered that the probability that the vehicle owner remotely controls the vehicle within a period of time after the account is logged in is high, and therefore, in the standby mode 3, the Tbox needs to keep a long connection with the server within the second delay, and the Tbox periodically sends a heartbeat packet to the server through timing to keep the long connection between the Tbox and the server until the Tbox is awakened within the second delay or the Tbox is not awakened after the second delay, and the long connection between the Tbox and the server is closed.
In order to further improve the success rate of waking up the Tbox, after the Tbox enters the standby mode 3, the method further includes: and when the second awakening instruction is received in the second delay to enter the awakening state, sending response information to the second awakening instruction to the server. Specifically, after the Tbox receives a data wakeup instruction issued by the server, the Tbox enters a wakeup state and responds to the data wakeup instruction, and sends response information to the data wakeup instruction to the server, and if the server does not receive response information fed back by the Tbox within a set time, for example, within 1S after sending the data wakeup instruction to the Tbox, it is considered that the data wakeup to the Tbox is unsuccessful, and therefore a short message wakeup instruction is continuously sent to the Tbox as a backup, so as to ensure a wakeup success rate.
In a second aspect of the present embodiment, a Tbox sleep/wake control method is provided, which is applied to a server, and includes:
sending a first awakening instruction to the vehicle-mounted Tbox;
