Compared with the prior art, the switching method of the working modes of the equipment, the micro-control device and the ship positioning system can automatically and intelligently adjust the working modes of the equipment according to the real-time change of an application scene so as to reduce the consumption of the battery of the equipment and prolong the service time of the battery after single charging, thereby effectively realizing the low power consumption of the equipment; the invention is applied to a ship positioning system, effectively prolongs the service time of the single electric quantity of the battery on the premise of not influencing the positioning effect, can prolong the service time of the single charging of the battery by more than one time according to the theoretical value estimation, greatly reduces the maintenance work of frequent charging of the battery in the use process, and simultaneously greatly prolongs the service life of the battery.
As shown in fig. 1, in an embodiment, the method for switching the operating mode of the apparatus of the present invention is applied to a micro-control device.
Specifically, the micro control device includes a control module 11, a power management module 12, a wireless transceiver module 13 and a device 14; the power management module 12 is connected to the control module 11, the wireless transceiver module 13, and the device 14, and configured to supply power to the control module 11, the wireless transceiver module 13, and the device 14; the wireless transceiver module 13 is connected to the control module 11, and is configured to receive wireless data and send the wireless data to the control module 11; the control module 11 is connected to the device 14, and is configured to switch an operating mode of the device 14.
It should be noted that the wireless transceiver module 13 transmits the wireless data to the relevant data register in the control module 11 through the SPI bus.
It should be noted that when the control module 11 is in a standby or sleep state and the wireless transceiver module 13 sends wireless data to the control module 11, waking up the control module 11 is also implemented.
Further, when the control module 11 is in a standby or sleep state and the wireless transceiver module 13 does not receive wireless data, the wireless transceiver module 13 may wake up the control module 11 through a timer interrupt.
It should be noted that the operation modes of the device include a normal mode, a standby mode and a sleep mode.
As shown in fig. 2, in an embodiment, the method for switching the operating modes of the device includes the following steps:
step S1, when the device is in the normal mode, determining whether the wireless transceiver module receives the wireless data within a first preset time period.
It should be noted that, after the device is powered on, the device automatically enters a normal mode, at this time, the wireless transceiver module can normally receive and transmit wireless data, and the control module can also normally process calculation data and manage the device.
Specifically, when the device is in the normal mode, the control module may determine whether the wireless transceiver module receives the wireless data within a first preset time period (if the wireless transceiver module receives the wireless data, the wireless transceiver module may send the wireless data to the control module, so that the control module may know that the wireless transceiver module receives the wireless data, and if the control module does not receive the wireless data sent by the wireless transceiver module, the control module may naturally know that the wireless transceiver module does not receive the wireless data within the first preset time period).
It should be noted that the first preset time period is a preset fixed value, and is specifically set to what number, which is not a condition for limiting the present invention, and may be set according to different practical application scenarios.
Preferably, the first preset time period is set to 5 minutes.
Step S2, when the wireless transceiver module does not receive the wireless data within the first preset time period, the control module switches the operating mode of the device to the standby mode.
It should be noted that, if the wireless transceiver module receives the wireless data within the first preset time period, the operating mode of the device does not need to be switched, that is, the device is still in the normal mode.
Step S3, when the device is in the standby mode, determining whether the wireless transceiver module receives the wireless data within a second preset time period.
It should be noted that the second preset time period is a preset fixed value, and is specifically set to what number, which is not a condition for limiting the present invention, and can be set according to different practical application scenarios.
Further, the second preset time period is greater than the first preset time period.
Preferably, the second preset time period is set to 30 minutes.
In an embodiment, when the device is in the standby mode, the power management module and the wireless transceiver module both work normally, and the control module is in a standby state.
In an embodiment, when the wireless transceiver module receives the wireless data within the second predetermined time period, the wireless transceiver module wakes up the control module to switch the operating mode of the device to the normal mode.
It should be noted that, when the device is in the standby mode, the control module is in the standby state, and at this time, if the wireless transceiver module receives the wireless data within the second preset time period, the wireless transceiver module sends the wireless data to the control module, and on one hand, wakes up the control module; on the other hand, after waking up the control module, the control module is enabled to receive the wireless data, thereby determining that the wireless transceiver module receives the wireless data within a second predetermined time period, and when the control module determines that the wireless transceiver module receives the wireless data within the second predetermined time period, the control module further switches the operating mode of the device from the original standby mode to the normal mode.
Step S4, when the wireless transceiver module does not receive the wireless data within the second preset time period, the control module switches the operating mode of the device to the sleep mode.
In an embodiment, the wireless transceiver module wakes up the control module at a regular time, so that the control module switches the working mode of the device to the sleep mode when the wireless transceiver module does not receive the wireless data within the second preset time period.
It should be noted that the control module is awakened when in the standby state, not only after receiving the wireless data sent by the wireless transceiver module, but also the wireless transceiver module is periodically interrupted to awaken the control module, so that when the wireless transceiver module does not receive the wireless data within the second predetermined time period (because the wireless transceiver module does not send the wireless data to the control module, the control module cannot be awakened by the wireless data), the control module is awakened by the timed interruption (after the control module is awakened, since the control module does not receive the wireless data sent by the wireless transceiver module, it can be determined that the wireless transceiver module does not receive the wireless data within the second predetermined time period), and when the control module determines that the wireless transceiver module does not receive the wireless data within the second predetermined time period, it will further switch the operation mode of the device from the original standby mode to the sleep mode.
In one embodiment, the wireless transceiver module is in a sleep state when the device is in the sleep mode; the dormant state is a dormant stage which is continuously repeated; the sleep stage is as follows: the wireless transceiver module works in a third preset time period and sleeps in a fourth preset time period.
It should be noted that, after the device enters the sleep mode, the sleep state of the wireless transceiver module is a sleep stage that is continuously repeated, and in the whole process of the sleep stage, the wireless transceiver module is not completely in the sleep state, but has a continuous time period (corresponding to the third preset time period), the wireless transceiver module is normally operated, and in another continuous time period (corresponding to the fourth preset time period), the wireless transceiver module is in sleep.
Further, the sum of the time of the third preset time period and the time of the fourth preset time period is just equal to the time corresponding to a sleep stage.
It should be noted that, in the sleep stage, the wireless transceiver module may enter the third preset time period first, or enter the fourth preset time period first, that is, when the device enters the sleep mode, the wireless transceiver module may keep working normally in the third preset time period first, and then enter the sleep state in the fourth preset time period immediately; or the sleep mode is entered before the fourth preset time period, and then the normal operation is performed in the third preset time period; as long as it is ensured that the first sleep phase entered by the wireless transceiver module is the same after the subsequent repeated sleep phases are entered into the sleep mode by the device.
It should be noted that the third preset time period and the fourth preset time period are preset fixed values, and are specifically set as what number, which is not used as a condition for limiting the present invention and can be set according to different practical application scenarios; considering that the wireless transceiver module can still receive wireless data while ensuring low power consumption, it is preferable to set the third preset time period to 100 ms and the fourth preset time period to 900 ms, so that even if a wireless data is transmitted to the wireless transceiver module just at the beginning of the fourth preset time period, the wireless data can be received by the wireless transceiver module after the lapse of 900 ms (the duration of a wireless data is more than 1 s) although the wireless data cannot be received by the wireless transceiver module during the whole fourth preset time period.
It should be noted that, when the device is in the sleep mode, the wireless transceiver module may be in a normal operating state all the time in consideration of low power consumption of the wireless transceiver module.
In an embodiment, when the device is in the sleep mode, the method for switching the operating mode of the device further includes the following steps:
step S5, determining whether the wireless transceiver module receives the wireless data within the third predetermined time period.
In one embodiment, the control module is in a sleep state when the device is in the sleep mode.
Step S6, when the wireless transceiver module receives the wireless data within the third predetermined time period, the control module switches the operating mode of the device to the normal mode.
In an embodiment, when the wireless transceiver module receives the wireless data within the third predetermined time period, the wireless transceiver module wakes up the control module to switch the operating mode of the device to the normal mode.
It should be noted that, when the device is in the sleep mode, the control module is in the sleep state, and at this time, if the wireless transceiver module receives the wireless data within the third preset time period, it will send the wireless data to the control module, and on one hand, will wake up the control module; on the other hand, after waking up the control module, the control module is enabled to receive the wireless data, so as to determine that the wireless transceiver module receives the wireless data within a third predetermined time period, and when the control module determines that the wireless transceiver module receives the wireless data within the third predetermined time period, the control module further switches the operating mode of the device from the original sleep mode to the normal mode; if the wireless transceiver module does not receive the wireless data within the third preset time period, no wireless data is sent to the control module, that is, the control module is still in the sleep state, and certainly, the control module cannot switch the working mode of the device, that is, the working mode of the device is still in the sleep mode.
It should be noted that the protection scope of the method for switching the operating modes of the device according to the present invention is not limited to the execution sequence of the steps listed in this embodiment, and all the solutions implemented by adding, subtracting, and replacing steps in the prior art according to the principle of the present invention are included in the protection scope of the present invention.
