Abstract
The utility model is a kind of for the uncharged early warning protector of frame direct current accumulation of energy storage battery, comprises DC power source unit, direct current accumulation of energy storage battery, direct supply identifying unit, display and switch element.The utility model is simple and practical, can carry out early warning and protection to storage battery is uncharged, extends the serviceable life of storage battery, reduces machine maintenance cost.
Description
Technical field
The utility model relates to frame control field, is specially a kind of for the uncharged early warning protector of frame direct current accumulation of energy storage battery.
Background technology
It is by multiple transducer drive motor driver mostly that existing frame controls, in order to allow each power wheel of frame synchronous or run with certain proportion relation and machine right position can be made to stop when improper power-off, direct current accumulation of energy storage battery can be used in frame control.But in the uncharged situation of direct current accumulation of energy storage battery, the electricity of direct current accumulation of energy storage battery is limited, if Use out of range or shortcoming can damage direct current accumulation of energy storage battery, reduce serviceable life, increase machine maintenance cost.
Summary of the invention
The purpose of this utility model is to provide a kind of for the uncharged early warning protector of frame direct current accumulation of energy storage battery, simple and practical, carrying out early warning and protection, extend the serviceable life of storage battery, reduce machine maintenance cost to storage battery is uncharged.
The utility model is achieved by the following technical solution:
A kind of for the uncharged early warning protector of frame direct current accumulation of energy storage battery, comprise DC power source unit, direct current accumulation of energy storage battery, direct supply identifying unit, display and switch element; Wherein, the input end of DC power source unit is connected with electrical source of power, output terminal is connected with direct current accumulation of energy storage battery; The output terminal of direct current accumulation of energy storage battery is connected with load by switch element; Whether direct supply identifying unit is normal for judging that direct supply exports, and direct supply identifying unit is coupled with DC power source unit and switch element respectively, is connected again with display simultaneously.Each working cell in the utility model is all hardware cell, and direct supply identifying unit realizes its function by mimic channel.The former machine of DC power source unit is the power supply of 27V to 28V with an output, and when direct current accumulation of energy storage battery is uncharged, voltage is 24V, and during charging, voltage equals DC power source unit voltage.Direct supply identifying unit compares the voltage on direct current accumulation of energy storage battery, and normal close to judging during DC power source unit output voltage that DC power source unit exports, time uncharged close to storage battery, voltage judges that DC power source unit output is abnormal.
The utility model compared with prior art has following beneficial effect: simple and practical, can carry out early warning and protection to storage battery is uncharged, extends the serviceable life of storage battery, reduces machine maintenance cost.
Accompanying drawing explanation
Fig. 1 is connection diagram of the present utility model.
Embodiment
Do to state further to the utility model below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of for the uncharged early warning protector of frame direct current accumulation of energy storage battery, comprise DC power source unit, direct current accumulation of energy storage battery, direct supply identifying unit, display and switch element, wherein, the input end of DC power source unit is connected with electrical source of power, output terminal is connected with direct current accumulation of energy storage battery, the output terminal of direct current accumulation of energy storage battery is connected with load by switch element, when normal power supply, DC power source unit is the charging of direct current accumulation of energy storage battery and powering load, direct supply identifying unit is connected with display, also be coupled with DC power source unit and switch element respectively simultaneously, when direct supply exports abnormal, direct current accumulation of energy storage battery starts powering load, it is abnormal that direct supply identifying unit detects that DC power source unit exports simultaneously, result is outputted to display, display can carry out early warning by sound or light etc., if early warning is not removed within the time of setting, then direct supply identifying unit controls switch unit, cut off the connection of direct current accumulation of energy storage battery and load, and play the effect of protection direct current accumulation of energy storage battery.
