Problems solved by technology

[0003] If the maintenance personnel of the excavator forget to run the engine on time, the battery will lose power and the excavator cannot be started. If the power loss is serious, the battery needs to be replaced
[0004] In the prior art, the power of the battery is directly monitored, and a signal is automatically sent to charge when the power is insufficient. Although the above problems are solved, the interaction between the length of engine shutdown and the power of the battery cannot be monitored, and the performance of the battery cannot be fed back.

Embodiment 1

[0027] Please refer to figure 1 , the present embodiment provides a battery charging feedback system, which can be applied to equipment such as excavators. When these equipments are working, the engine 1 of the equipment has its own generator to automatically charge the battery 3, and the power stored in the battery 3 ensures that the equipment can start normally. But when equipment does not work for a long time, the electric quantity of accumulator 3 can be lost, and at this moment needs to start equipment to make engine 1 run and thus accumulator 3 is charged. This embodiment provides a battery charge feedback system, which can automatically monitor the power condition of the battery 3 and the operation of the engine 1. When the battery 3 is running out of power, it can automatically send a signal to remind the user to start the engine 1 to charge the battery 3. At the same time, it can also monitor and feed back the power usage time of the battery 3 to reflect the performan...

Embodiment 2

[0056] Such as image 3 As shown, this embodiment provides a control method for a battery charging feedback system, using the above-mentioned battery charging feedback system, the method includes:

[0057] S100: judging whether the engine 1 speed is lower than a preset value of the speed.

[0058] S110: when the rotation speed of the engine 1 is lower than the preset rotation speed value, the first timer 4 starts timing.

[0059] The rotational speed of the engine 1 is obtained according to the rotational speed signal of the rotational speed sensor 7 , and when the rotational speed is lower than a preset value of the rotational speed, the first timer 4 is started to count time.

[0060] S120: The duration exceeds a first preset duration.

[0061] When the rotation speed is lower than the preset value of the rotation speed, it is determined that the engine 1 is in a shutdown state, and the duration recorded by the first timer 4 is the shutdown duration of the engine 1 .

Abstract

The invention provides a storage battery charging feedback system and its control method, and an excavator, which belong to the technical field of monitoring systems and include: a host and a monitor. The host is equipped with a main controller, an engine and a battery, and the main controller is connected to the monitor for signals. , to send a working signal to the monitor, the engine and the battery are electrically connected to charge the battery in the starting state; it also includes a first timer, a rotational speed sensor and a voltage sensor, and the rotational speed sensor is arranged on the engine for obtaining the rotational speed of the engine; The first timer is connected to the main controller, and the main controller triggers the first timer to count; the voltage sensor is used to detect the voltage of the storage battery; the duration recorded by the first timer is longer than the first preset duration or the voltage of the storage battery recorded by the voltage sensor When the voltage is less than the preset value, the main controller sends a working signal to the monitor. It can automatically monitor the power of the battery, and automatically send a reminder signal to the user when the power is low.

Description

technical field [0001] The invention relates to the technical field of monitoring systems, in particular to a storage battery charging feedback system, a control method thereof, and an excavator. Background technique [0002] The excavator battery is a maintenance-free battery, that is, the engine's own generator automatically charges the battery when the excavator is working. When the excavator is not working for a long time, the maintenance personnel of the excavator need to run the engine regularly to charge the battery. [0003] If the maintenance personnel of the excavator forget to run the engine on time, the battery will lose power and the excavator will not start. If the power loss is serious, the battery needs to be replaced. [0004] In the prior art, the power of the battery is directly monitored, and a signal is automatically sent to charge when the power is insufficient. Although the above problems are solved, the interaction between the length of engine shutdo...
