The input voltage is compared based on the high and low input levels. A low output level indicates insufficient power, while a high output level indicates normal power. This utility model, through the setting of the battery management module, can monitor the power consumption of the lithium battery in real time during use and promptly remind personnel when the power is low, facilitating timely replacement. This effectively reduces the situation where the low-power manhole cover alarm body stops working due to insufficient power, affecting monitoring and anti-theft, and improves the stability of the low-power manhole cover alarm body.

[0036] Working principle: In use, the low-power manhole cover alarm body can be fixed to the bottom of the manhole cover by using the first bolt hole 201 and external bolts. The sensor, microcontroller, communication module and alarm on the low-power manhole cover alarm body work together to monitor the condition of the manhole cover. The monitoring data is transmitted to the monitoring terminal through the communication module. The monitoring terminal can understand the condition of the manhole cover in real time. When the manhole cover is detected to have changed, the alarm will be issued and transmitted to the monitoring terminal to remind the personnel. The specific monitoring principle of the low-power manhole cover alarm body is existing technology and will not be described in detail here.

[0037] The low-power manhole cover alarm is powered by a lithium battery. As the battery's charge decreases, the output voltage also decreases. The battery output voltage is sent to a voltage detection circuit. Resistors R5, R4, and R6 in this circuit divide the input voltage. This voltage division, combined with a high-level input voltage, controls transistor Q1 to conduct. The voltage output is achieved through the conduction of transistor Q1. During this voltage output process, capacitors C2 and C1 filter the voltage, and Zener diode D1 further stabilizes the output voltage. This stabilized voltage is then input to a voltage comparator circuit. Comparators U1 and U2 in this circuit compare the output voltage twice with a set voltage threshold. The "+" input terminals of comparators U1 and U2... When the voltage is higher than the "-" input voltage, comparators U1 and U2 output a high level; when the "+" input voltage is lower than the "-" input voltage, comparators U1 and U2 output a low level. When the output is low, it is determined that the lithium battery is in a low-power state. When the lithium battery voltage is lower than the set threshold, comparator U2 will output a low-power alarm signal and transmit the alarm signal to chip U3. Chip U3 controls the power warning device to issue an alarm to remind personnel. The alarm signal is also transmitted to the monitoring terminal, which facilitates timely detection and replacement of the lithium battery by the personnel at the monitoring terminal. By monitoring the power status of the lithium battery in real time during use and reminding personnel in time when the power is low, it is convenient for personnel to replace the battery in time. This can effectively reduce the situation where the low-power manhole cover alarm body stops working due to insufficient power, which affects the monitoring and anti-theft.
