[0002] In the case of a general garden tool controller with two packages connected in series, the discrete signal cannot be detected, or the discrete signal is very weak, and relevant data information cannot be captured correctly
In the case of the existing dual battery packs connected in series, it is impossible to detect the high and low levels of discrete signals, so that it is impossible to judge which battery pack to use reasonably, and it is also impossible to issue correct control commands to achieve effective application and effective control of the battery pack, thereby failing to achieve Effective application of dual battery packs connected in series to the complete garden tool

The invention discloses a discrete signal detection circuit with two battery packs in series connection. A first battery pack unit comprises a first battery pack and a first triode. The positive electrode of the first battery pack is connected with the P+ pin of a master control unit, and the negative electrode of the first battery pack is connected with the P- pin of the master control unit and the emission electrode of the first triode. The output end of an optocoupler unit is connected with the first signal detection end of the master control unit and forward input voltage. A second batterypack unit comprises a second battery pack and a second triode. The positive electrode of the second battery pack is connected with the P- pin of the master control unit. The collection electrode of the second triode is connected with the forward input voltage and the second signal detection end of the master control unit. According to the discrete signal detection circuit with two battery packs in series connection, the relevant data information of the series battery packs can be automatically detected and the relevant data information can be fed back to the master control unit, and the master control unit can judge and issue a command according to the relevant information so that the battery packs can be effectively utilized and protected.
Description
Technical field [0001] The present invention relates to the technical field of signal detection, in particular to a discrete signal detection circuit connected in series with double battery packs. Background technique [0002] In the case of a general garden tool controller with two packages connected in series, the discrete signal cannot be detected, or the discrete signal is very weak, and the relevant data information cannot be captured correctly. When the existing dual battery packs are connected in series, it is impossible to detect the high and low levels of the discrete signals, so it is impossible to judge which battery pack is to be used reasonably, and it is impossible to issue the correct control commands to realize the effective application and effective control of the battery pack. The corresponding role of double battery packs in series is effectively applied to the whole garden tool machine. Summary of the invention [0003] In view of the shortcomings in the prior...
