Description
Technical field
The utility model relates to a kind of power module showing power down time, particularly relates to a kind of electronic ink screen that utilizes and loses a time to what learn power module.
Background technology
Power module, as the power supply supply of various equipment and spacer assembly, is widely used in the fields such as Machine-Tool Control, communication and electric power.On some unattended equipment, because polling period is longer, be difficult to the power fail that Timeliness coverage a variety of causes causes, thus affect the work such as the analysis of fault.
Utility model content
The utility model is for the deficiencies in the prior art, provides a kind of power module showing power down time.
The purpose of this utility model realizes by following technical solution:
A kind of power module showing power down time, comprise single-chip microcomputer, it is characterized in that, also comprise the electronic ink screen, AC/DC module, the outgoing management circuit that are connected with single-chip microcomputer respectively, the input end of described AC/DC module is used for being connected with electric power system, and output terminal is connected with the input end of outgoing management circuit, and the output terminal of described outgoing management circuit is used for being connected with load, being connected with electronic ink screen of the output terminal of described single-chip microcomputer, refresh display current time for driving electronic ink screen.
Further, also comprise the charge-discharge modules be connected with single-chip microcomputer, described charge-discharge modules is connected with accumulator, and the input end of described charge-discharge modules is connected with the output terminal of described AC/DC module, and output terminal is connected with the input end of described outgoing management circuit.
Further, also comprise and being connected with the input end of single-chip microcomputer, for controlling the switch that power module runs.
The utility model has following beneficial effect:
The utility model mainly utilizes electronic ink screen to have bistable display performance, electronic ink screen is applied in power module, when civil power cannot be powered to power module, the uncontrollable electronic ink screen of single-chip microcomputer refreshed the time, so the time of electric ink screen display would not change, so when patrol officer patrols and examines equipment, time of electric ink screen display be power module lose the electricity time.
Single-chip microcomputer can be used for various exception in writing task and failure message, drives electronic ink screen refresh time simultaneously.
Under commercial power supply is normal, be charge in batteries through charge-discharge modules, after civil power is lost, can switch to accumulator is that equipment is powered, when the electricity of accumulator exhausts, the time of electronic ink screen also cannot refresh, so when patrol officer patrols and examines equipment, time of electric ink screen display be power module lose the electricity time.
Accompanying drawing explanation
Fig. 1 is the internal wiring functional block diagram of power module.
Fig. 2 is the connection diagram of power module and equipment.
Embodiment
A kind of power module 1 showing power down time that the utility model provides, as depicted in figs. 1 and 2, comprises single-chip microcomputer 11, the electronic ink screen 12 be connected with single-chip microcomputer 11 respectively, AC/DC module 13, outgoing management circuit 14.Function and the annexation of each parts are described below:
The output terminal of AC/DC module 13 is connected with the input end of outgoing management circuit 14, and the input end of AC/DC module 13 is used for being connected with electric power system, and described electric power system can be specifically civil power 2.
The output terminal of outgoing management circuit 14 is connected with load 3, for powering for the equipment in load 3.
The output terminal of single-chip microcomputer 11 is connected with the input end of electronic ink screen 12 and drives electronic ink screen 12 to refresh to show current time.
When civil power 2 cannot be powered to power module 1,12 pairs of times of the uncontrollable electronic ink screen of single-chip microcomputer 11 refresh, so the time that electronic ink screen 12 shows would not change, so when patrol officer patrols and examines the equipment in load 3, on electronic ink screen 12 display time be power module 1 lose electricity the time.
The power module 1 that the utility model provides can also be provided with charge-discharge modules 15, charge-discharge modules 15 input end is connected with AC/DC module 13, output terminal is connected with the input end of outgoing management circuit 14, charge-discharge modules 15 is also connected with accumulator 4, supply normally at civil power 2, charge for accumulator 4 through charge-discharge modules 15, after civil power 2 is lost, can switch to accumulator 4 is that equipment in load 3 is powered, the time exhausting electronic ink screen 12 when the electricity of accumulator 4 also cannot refresh, so when patrol officer patrols and examines load 3, on electronic ink screen 12 display time be power module 1 lose electricity the time.
The power module 1 that the utility model provides can also be provided with switch 16, and described switch 16 is connected with the input end of single-chip microcomputer 11, for the operation of control single chip computer 11.
The above, be only preferred embodiment of the present utility model, therefore can not limit with this scope that the utility model implements, the equivalence namely done according to the utility model claim and description change with modify, all should still belong in scope that the utility model patent contains.
