fig. 2 is a flowchart in an embodiment of the present invention.
Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The principles and construction of the present invention will be described in detail below with reference to the drawings and examples.
As shown in fig. 1 and 2, the present invention provides a protection device for an electric control cabinet, including: self-locking device, door closing device, shimmer sensor and controller. After the self-locking device is opened, the electric control cabinet is powered on, and the cabinet door is closed, the cabinet door can be automatically locked by action, after the action, the locked cabinet door can send an action signal, and after the action is not carried out, the unlocked cabinet door can send an action signal; the door closing device can close the cabinet door according to the control signal, and the low-light sensor is arranged in the electric control cabinet and can detect light intensity and send different light intensity signals according to the intensity of light; when the electric control cabinet is powered on and the light intensity signal exceeds the preset threshold value, the controller controls the door closing device to automatically close the cabinet door when the self-locking device sends a non-action signal. Make the user need not the manual cabinet door that closes, increase self-locking function. Can avoid the staff to neglect to forget the condition emergence of closing cabinet door or locking cabinet door, intelligent high improves the security of automatically controlled cabinet greatly, prevents that someone from opening the cabinet door when the circular telegram and causing the accident, perhaps causes the internal ash that falls of cabinet, damages such as damp, corruption.
When the electric control cabinet is powered on and the self-locking device is locked to send an action signal, the controller switches on or off the power supply of the electric control cabinet. In another embodiment, before the controller switches on or off the power supply of the electric control cabinet, whether the light intensity signal exceeds a second preset threshold value can be further judged, and if so, the controller switches off the power supply of the control cabinet. Because of self-lock device sends the action signal, then explains that the cabinet door has closed, and the light that shimmer sensor received this moment is the highlight of the inside production of automatically controlled cabinet, for example power device explodes and splits or other components and parts damage produces the light arc etc. can avoid continuously receiving the influence this moment through automatic power off, and equipment in the automatically controlled cabinet of timely accurate protection reduces the loss to the minimum.
The invention also comprises an alarm device and an energy storage module, wherein the alarm device is controlled to alarm when the controller cuts off the power supply of the electric control cabinet according to the light intensity signal. The alarm device can be a sound-light alarm device and can remind workers to treat as soon as possible.
The energy storage module can supply power for the protection device, and the energy storage module stores energy when the electric control cabinet is electrified. When the user overhauls and accomplishes, if appear forgetting the condition of closing the door, for energy storage module storage electric energy when the automatically controlled cabinet is electrified before can using, wait to charge energy storage module once more after the electricity is gone up, close the door self-locking action once more.
In a specific embodiment, the controller, i.e., the main control chip, is a DSP, and can collect data in real time. The door closing device is provided with the motor, the motor driving unit and the chain, so that the door can be pulled to be closed in a mode that the motor is driven by controlling the motor driving unit through the controller and the chain is matched, and the door can be automatically closed in other realizable modes, and the door closing device is within the protection scope of the invention.
The self-locking device can be manually opened and closed, and when the self-locking device needs to be electrified for maintenance, a maintenance worker can manually close the self-locking device to prevent the self-locking device from being electrified and trigger the controller to control the door closing device to close the cabinet door.
The invention also comprises a watchdog, a timer and a display module, after being electrified, the watchdog, the timer, the display module and the control logic of the controller are initialized, and the timer is interrupted. The program is divided into a main cycle program and a timer processing program, the program enters the main cycle program after the program is started, when the timer processing program is executed by the system after the timing time is up, and the main cycle program and the timer processing program are mutually matched to jointly realize the control of the protection device.
Meanwhile, the invention can also carry Bluetooth, voice and WIFI functions, can enable users to control the voice, and is convenient for use in occasions with special requirements.
