Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 is a block diagram of the basic structure of a bluetooth tracking device in an embodiment of the present invention. Only portions related to the embodiments of the present invention are shown for convenience of explanation.
Referring to fig. 1, the bluetooth tracking device 1 in the embodiment of the present invention includes a processor 11 and a modem 12, and the processor 11 and the modem 12 are connected through a serial communication interface. The processor is a bluetooth low energy processor, and an RTOS operating system runs on the processor 11. The operating modes of the RTOS operating system in the running state comprise a BLE mode and an LTE mode. Wherein, under BLE mode, bluetooth tracking equipment 1 has established the bluetooth with the intelligent terminal that the user carried and is connected, passes through bluetooth communication between the two. In the LTE mode, the processor 11 in the bluetooth tracking device 1 is in the bluetooth low energy broadcast mode, the broadcast message needs to be transmitted to the modem 12 through a serial port, and the modem 12 sends the message to the intelligent terminal carried by the user through wireless communication.
The following embodiments of the present invention are proposed based on the basic structural block diagram of the above-described bluetooth tracking apparatus 1.
Example one
Fig. 2 is a schematic flow chart illustrating an implementation process of a method for switching a serial port working state according to an embodiment of the present invention. The method is performed by the processor 11 in the bluetooth tracking device 1 shown in fig. 1. Referring to fig. 2, the method for switching the serial port working state provided in this embodiment includes the following steps:
step S201, when the bluetooth tracking apparatus 1 is in the LTE mode, monitoring the bluetooth running state of the processor 11 in real time, where the bluetooth running state includes a bluetooth broadcast state and a bluetooth idle state.
The bluetooth tracking device 1 has two ways to enter the LTE mode: one is that after the bluetooth tracking device 1 is started and after the bluetooth tracking application program on the intelligent terminal carried by the user is registered and bound, the bluetooth tracking device 1 is in the LTE mode; the other is that when the bluetooth tracking device 1 and the smart terminal are in a bluetooth connection state, the bluetooth tracking device 1 is in a BLE mode, and when the bluetooth connection is disconnected, the bluetooth tracking device 1 automatically switches to an LTE mode.
In the LTE mode, the processor 11 within the bluetooth tracking device 1 is in a bluetooth low energy broadcast mode. In the bluetooth low energy broadcast mode, the broadcast state of the bluetooth low energy tracking device is to periodically send packets, scan surrounding connectable smart devices, and assuming that the total duration of one broadcast period is T, the processor 11 sends the broadcast packets within a time T1, and is in an idle state within a time T2, where T is T1+ T2. Then, during time T1, the bluetooth active state of processor 11 is in the bluetooth broadcast state; during time T2, the bluetooth low energy bluetooth active state is in a bluetooth idle state. Referring to fig. 3, T2 is typically about 99% of the time during a broadcast cycle.
Step S202, when the Bluetooth running state is a Bluetooth broadcasting state, loading the serial port; and when the Bluetooth running state is a Bluetooth idle state, unloading the serial port.
In this embodiment, when the bluetooth running state of the processor 11 is the bluetooth broadcasting state, the serial port driver is synchronously loaded and a serial port initialization action is performed, so that the serial port task in the processor 11 is also in a working state; when the bluetooth running state of the processor 11 is idle and the broadcast data packet is not sent, the unloaded serial port is synchronously driven, and the serial port is closed. Because bluetooth tracking equipment 1 is under LTE mode, and every bluetooth broadcast cycle only has 1% of the time to be in the bluetooth broadcast state, consequently, after synchronous bluetooth broadcast state and serial ports operating condition, can realize the low-power consumption of serial ports task, and then reduce bluetooth tracking equipment 1's consumption.
Optionally, in this embodiment, the method further includes:
when the Bluetooth tracking device 1 is in an LTE mode, starting a serial port and Bluetooth synchronous loading and unloading function of the Bluetooth tracking device 1;
and when the Bluetooth tracking device 1 exits the LTE mode, closing the serial port and Bluetooth synchronous loading and unloading function of the Bluetooth tracking device 1.
In this embodiment, when the serial port and bluetooth synchronous loading and unloading function of the bluetooth tracking apparatus 1 is started, the processor 11 of the bluetooth tracking apparatus 1 is triggered to monitor the bluetooth running state of itself in real time, and enters a processing procedure of switching the serial port working state. The serial port and the Bluetooth synchronous loading and unloading function is started only when the Bluetooth tracking device 1 is in the LTE mode, and the serial port and the Bluetooth synchronous loading and unloading function is closed when the Bluetooth tracking device 1 exits the LTE mode, so that the power consumption of the Bluetooth tracking device 1 can be further saved.
As can be seen from the above, in the method for switching the serial port working state provided in this embodiment, when the bluetooth tracking apparatus 1 is in the LTE mode, the bluetooth running state of the processor 11 is monitored in real time; when the Bluetooth running state is a Bluetooth broadcasting state, loading the serial port; and when the Bluetooth running state is the Bluetooth idle state, the serial port is unloaded, so that the working states of the serial port and the Bluetooth can be synchronized, the low power consumption of the serial port task is realized, and the overall power consumption of the Bluetooth tracking device 1 is reduced.
Example two
Fig. 4 is a schematic flow chart illustrating an implementation process of the method for switching the serial port working state according to the second embodiment of the present invention. The method is performed by the processor 11 in the bluetooth tracking device 1 shown in fig. 1. Referring to fig. 3, the method for switching the serial port working state provided in this embodiment includes the following steps:
step S401, when the Bluetooth tracking device 1 is in an LTE mode, monitoring the Bluetooth running state of the processor 11 in real time, wherein the Bluetooth running state comprises a Bluetooth broadcasting state and a Bluetooth idle state;
step S402, when the Bluetooth running state is a Bluetooth broadcasting state, loading the serial port; and when the Bluetooth running state is a Bluetooth idle state, unloading the serial port.
It should be noted that, since the implementation manners of the steps S301 to S302 in this embodiment are completely the same as those of the steps S201 to S202 in the previous embodiment, the description is omitted here.
Step S403, when receiving a control instruction for requesting serial port communication input by a user, determining whether a bluetooth running state of the processor 11 is in a bluetooth idle state, if yes, entering step S404; if not, the process goes to step S407.
And S404, loading the serial port.
In this embodiment, the processor 11 is provided with a key at a side thereof, and a user can operate the key, for example: the single click, the double click and the triple click correspondingly generate key sequences with different meanings, the key sequences are sent to the modem 12 side from the processor 11 through the serial port, and the modem 12 realizes different functions according to different key values. Wherein, each key sequence corresponds to a control instruction.
In this embodiment, when receiving a control instruction input by a user through a key, the processor 11 determines that the bluetooth motion state is in the bluetooth idle state, and loads and initializes the serial port to switch the serial port from the off state to the on state, so that the processor 11 can send the control instruction to the Modem through the serial port, and the Modem completes a corresponding control function according to the control instruction.
Step S405, after the control instruction is sent to the modem 12 through the serial port, determining whether the bluetooth running state of the processor 11 is still in a bluetooth idle state, and if the bluetooth running state is still in the bluetooth idle state, entering step S406; if the bluetooth operation state is switched to the bluetooth broadcast state, the process proceeds to step S407.
And S406, unloading the serial port.
And step S407, keeping the working state of the serial port unchanged.
In one specific implementation example, the user key press action and the corresponding bluetooth tracking device 1 response function are as follows:
in this embodiment, the GPS required for positioning and the microphone required for recording by the bluetooth tracking apparatus 1 are both disposed at the Modem side, and after the user performs a key pressing operation, the key sequence is only required to be sent to the Modem side through the serial port, and the remaining function modems can be performed by themselves without depending on the processor 11 and the serial port. Therefore, in this embodiment, after the control instruction is detected to be sent, if the bluetooth running state of the processor 11 is still in the bluetooth idle state, the serial port driver is unloaded, and the serial port is closed, so that the power consumption of the serial port can be saved, the power consumption of the whole bluetooth tracking device 1 is reduced, and the standby time of the bluetooth tracking device 1 in the emergency state is prolonged.
As can be seen from the above, compared with the previous embodiment, in the method for switching the working state of the serial port according to this embodiment, when the control instruction which is input by the user and requires serial port communication is received, and when it is detected that the bluetooth running state of the processor 11 is in the idle state, the serial port is loaded, so that the processor 11 can send the control instruction to the Modem through the serial port, and the bluetooth tracking device 1 can realize a corresponding control function; after the control instruction is sent and completed, when the Bluetooth running state of the processor 11 is still in the idle state, the serial port is unloaded, so that the power consumption of the serial port can be saved, the power consumption of the whole Bluetooth tracking device 1 is reduced, and the standby time of the Bluetooth tracking device 1 in the emergency state is prolonged.
