It should be noted that like reference numerals and letters refer to like items in the following figures, and thus once an item is defined or illustrated in one figure, no further detailed discussion or description thereof will be necessary in the following description of the figures.
Referring to fig. 1 and 2, the embodiment provides a reset switch circuit for a wireless sensor device of a coal mine, which comprises a battery pack, a change-over switch, a main control module, a reset module and an LED indicator lamp. The battery pack is electrically connected with the change-over switch, the main control module, the reset module and the LED indicator lamp, and provides electric energy for the change-over switch, the main control module, the reset module and the LED indicator lamp. It is noted that the battery pack includes, but is not limited to, a lithium-ion battery pack, which in the present embodiment is provided as a lithium-ion battery pack.
Specifically, the positive pole electric connection change over switch of group battery, change over switch electric connection main control module and reset module, wherein main control module electric connection LED pilot lamp and group battery's negative pole, reset module pass through LED pilot lamp electric connection group battery. It is noted that the main control module and the reset module are not directly electrically connected, and are two mutually independent circuits. In this embodiment, the reset module is electrically connected to the LED indicator through the alarm.
Further, the main control module comprises a main control chip, wherein the positive electrode of the battery pack is electrically connected with the public end of the change-over switch, the public end of the change-over switch is electrically connected with the normally-closed end of the change-over switch, the normally-closed end of the change-over switch is electrically connected with the 1 port of the main control chip, and the 2 port of the main control chip is electrically connected with the LED indicator lamp and the negative electrode of the battery pack. That is, when the main control chip works normally, the supply current of the battery pack flows to: the positive pole of the battery pack, the common end of the change-over switch, the normally closed end of the change-over switch, the main control chip and the negative pole of the battery pack form a complete loop, and the power supply voltage of the main control chip is 3.34V at the moment and is the normal power supply voltage, so that the normal work of the singlechip can be judged, and the program runs normally. It is worth noting that when the singlechip is in normal operation, a complete loop cannot be formed because the power supply current of the battery pack flows to the LED indicator lamp from the main control chip, so that the LED indicator lamp cannot work when the singlechip is in normal operation.
In this embodiment, the reset module includes a current limiting resistor R1, where the positive electrode of the battery is electrically connected to the common end of the change-over switch, the common end of the change-over switch is electrically connected to the normal open end of the change-over switch, the normal open end of the change-over switch is electrically connected to the current limiting resistor R1, the current limiting resistor R1 is electrically connected to the alarm, the alarm is electrically connected to the LED indicator, and the LED indicator is electrically connected to the negative electrode of the battery. Notably, the warning device includes, but is not limited to, an indicator light and a buzzer. In this embodiment, the warning indicator is selected as the indicator light, i.e. the indicator light a in fig. 2.
Further, when the reset is needed, the indicator lamp A works after the change-over switch is pressed. When the reset module operates, the power supply current flow direction of the battery pack is as follows: the positive pole of the battery pack, the common end of the change-over switch, the normally open end of the change-over switch, the current limiting resistor R1-A indicator lamp, the LED indicator lamp and the negative pole of the battery pack form a complete loop. The power supply current flow direction of the battery pack can be seen that after the change-over switch is pressed down, the switch is changed from normal close to normal open, and the power supply on the main control chip is disconnected, namely the main control chip stops supplying power, that is, the voltage on the main control chip is 0V at the moment. It is noted that in the reset module, the power supply current of the battery pack can form a complete loop after passing through the LED indicator lamp, so that when the reset is performed, the LED indicator lamp works, but the singlechip does not work.
Specifically, when the reset switch circuit works normally, the LED indicator lamp does not work, and only the main control chip works, so that only the power of the main control chip is consumed. When the reset is needed, the power supply of the main control chip is cut off, and only the LED indicator lamp works. Meanwhile, after the current-limiting resistor R1 is used, the current flowing to the LED indicator lamp is reduced and the power consumption is low. Therefore, whether the battery pack operates normally or not can be confirmed through the working state of the indicator lamp A in the reset switch, the working state of the main control chip can be confirmed, and the reset state of the equipment is ensured.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
