Problems solved by technology
[0003] The existing pig farm alarm does not have the function of lithium battery life detection, but only has the function of battery voltage detection. The state of the lithium battery is detected by detecting the voltage. After the lithium battery fails, it cannot be found in time. The reduction of lithium battery life leads to short alarm time, which cannot meet the existing alarm requirements
[0004] At present, the lithium battery capacity detection only supports the discharge power detection. Due to the particularity of the lithium battery use environment, it is necessary to keep the lithium battery with sufficient power in real time, and the discharge for the purpose of life testing cannot be performed.

The invention relates to a pig farm alarm rechargeable lithium battery life prediction method, which comprises a master control MCU, an alarm function module and a lithium battery charging module controlled by the master control MCU, and a lithium battery connected with the lithium battery charging module, a switching power supply part is additionally arranged between an alarm function module and a lithium battery charging module, and the lithium battery charger is characterized in that a capacity acquisition module is additionally arranged between a master control MCU and the lithium battery charging module, the master control MCU is connected with a key input module and a screen display module, a voltage-capacity curve is preset by the master control MCU, and the MCU performs control according to 11 steps. Compared with the prior art, a lithium battery service life detection circuit is integrated in the pig farm alarm, so that the service life of the lithium battery can be detected in real time, the lithium battery does not need to be taken out of the device for detection, and the situation that no lithium battery exists in the device when an alarm event occurs is avoided.
Description
technical field [0001] The invention relates to a data processing method for the purpose of prediction, in particular to a method for predicting the life of a rechargeable lithium battery of a pig farm alarm. Background technique [0002] The pig farm alarm is a controller that detects various types of alarm information on the pig farm. It is very important for the pig farm. If the alarm information cannot be resolved in time, there will be irreparable losses. Therefore, the pig farm alarm has a built-in recyclable lithium battery, and the pig farm alarm can also alarm in real time in the case of power failure. [0003] The existing pig farm alarm does not have the lithium battery life detection function, but only has the battery voltage detection function. The reduction of the life of the lithium battery leads to a short alarm time, which cannot meet the existing alarm requirements. [0004] At present, lithium battery capacity detection only supports discharge power dete...
