Description
Technical field
The utility model relates to the attending device of waking up certainly of a kind of power down protection, no external power supply, particularly a kind of power down protection and certainly awake attending device of no external power supply that is used for ink jet numbering machine.
Background technology
In a lot of applied field, ink jet numbering machine need carry out some necessary scene protections when unexpected power down, such as the information that is writing, current spray printing state or the like; When disconnecting when ink jet numbering machine shutdown a couple of days and with electrical network in addition, if time one length will cause the local obstruction of ink jet numbering machine, modal is spray nozzle clogging, so just must can start and carry out some necessary attended operations automatically when shutdown.
Up to now, the ink jet numbering machine industry does not also have a machine to realize power down protection simultaneously and does not have the maintenance function of waking up certainly of external power supply, will be greatly improved if realized the real-time of these function ink jet numbering machines and stability.
The utility model content
The purpose of this utility model is to provide a kind of power down protection and no external power supply from the attending device of waking up, and makes ink jet numbering machine can start and carry out necessary attended operation automatically after power down.
For reaching above technical purpose, the utility model provides following technical proposals:
A kind of power down protection and no external power supply are from the attending device of waking up; be used for the ink jet numbering machine power down protection and self-timing startup shutdown maintenance under the situation of no external power supply, comprise Switching Power Supply and batteries, power for respectively Switching Power Supply and batteries by the alternating current of electrical network input; wherein
Described Switching Power Supply is connected with microcontroller through the detection of power loss module, and described detection of power loss module is responsible for the output of pilot switch power supply, and sends the power-fail interrupt signal to microcontroller MCU;
Described batteries is as an outage servo power supply, connect charging module and battery condition detection module respectively, by detection of power loss module diverter switch power supply or batteries and conducting of ink jet numbering machine main power source or disconnection, send charging control signal by the monitoring of battery condition detection module and to charging module.
The utility model operation principle is as follows: after the electrical network that inserts disconnects, described switch power source output voltage will descend, when dropping to setting voltage, the detection of power loss module is promptly sent the power supply switching signal, the main power source of ink jet numbering machine switched to by batteries export, simultaneously the detection of power loss module is also sent power-fail interrupt to MCU, MCU is carried out close line of ink marker operation and a series of scene protection operation, and ink jet numbering machine was with closeall power component and be in holding state after operations was finished;
Simultaneously, batteries is also as an outage servo power supply, and after ink jet numbering machine cut off electrical network, batteries promptly provided power supply to the maintenance function of waking up certainly of ink jet numbering machine, guaranteed also can carry out from the maintenance function of waking up after the ink jet numbering machine shutdown.
For mating with the ink jet numbering machine main power source, on the such scheme basis, described switch power source output voltage is 24V.
On the such scheme basis, described batteries output voltage is the 24V direct current.
Superiority of the present utility model is: can start and carry out necessary attended operation automatically after power down, improve the stability of ink jet numbering machine greatly, and reduced maintenance significantly, make that user's experience is better, maintenance cost is well controlled.

Embodiment
Below in conjunction with description of drawings, the utility model is further described.
As shown in Figure 1; a kind of power down protection and no external power supply are from the attending device of waking up; be used for the ink jet numbering machine power down protection and self-timing startup shutdown maintenance under the situation of no external power supply; comprise Switching Power Supply 1 and batteries 2; give Switching Power Supply 1 and batteries 2 power supplies respectively by the 220V alternating current of electrical network input, wherein:
Described Switching Power Supply 1 is connected with microcontroller MCU through detection of power loss module 3, by the output of detection of power loss module 3 pilot switch power supplys, and to microcontroller MCU transmission power-fail interrupt signal;
Described batteries 2 is as an outage servo power supply, connect charging module 21 and battery condition detection module 22 respectively, by detection of power loss module 3 diverter switch power supplys 1 or batteries 2 and conducting of ink jet numbering machine main power source or disconnection, send charging control signal by 22 monitoring of battery condition detection module and to charging module 21, be used to control battery charging.
After the 220V electrical network that inserts disconnects, the 24V voltage of described Switching Power Supply 1 output will descend rapidly, when dropping to detection threshold voltage (minimum voltage value of setting), detection of power loss module 3 is promptly sent the power supply switching signal, the main power source of ink jet numbering machine is switched to by batteries 2 outputs, detection of power loss module 3 also will be sent power-fail interrupt to MCU simultaneously, MCU carries out immediately and closes line of ink marker operation and a series of scene protection operation, and ink jet numbering machine is with closeall power component and be in holding state after finishing;
Can send the power-fail interrupt signal at once when the detection of power loss module detects Switching Power Supply 24V output again after normal, notice MCU enters normal operating conditions and according to the field data that keeps ink jet numbering machine is adjusted to state before the power down;
Simultaneously, batteries 2 is also as an outage servo power supply, provides power supply to the maintenance function of waking up certainly of ink jet numbering machine, guarantees no matter whether ink jet numbering machine inserts the 220V electrical network, can both carry out from the maintenance function of waking up after the ink jet numbering machine shutdown.
