[0001] The present invention relates to the technical field of energy management and control systems, and in particular to an intelligent energy management and control system. Background Art

[0002] At present, energy control in various factories is basically applied for by on-site personnel, who sign pre-work and post-work tickets to determine whether there is maintenance work in the area. The approval process is cumbersome. Due to the lack of mandatory control measures, operations without tickets are common. Operations without tickets are serious violations of regulations, which will seriously threaten the lives of operators and do not comply with safety production regulations. Summary of the invention

DETAILED DESCRIPTION

[0010] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0011] like Figures 1 to 4As shown, an intelligent energy management and control system includes: a PC host 1, on which are connected several PC slaves 16; an edge WEB server 3, connected to the PC host 1; several management and control subsystems, respectively connected to the edge WEB server 3; the management and control subsystem includes: a regional I / O substation 4, connected to the edge WEB server 3; a KA2 relay 6, arranged on a control loop in a device control box; a KA3 relay 7, arranged on a control loop in a device control box; a micro switch 10; a martensitic stainless steel lock 14, hung on the outer wall of the device control box, and magnetically attracted to a magnetic ball on the device control box that can slide up and down; an iron connecting rod 15, the top of which is magnetically attracted to the magnetic ball, and the bottom of which is in contact with the switch handle of the micro switch 10; wherein, K A2 relay 6, including: KA2 normally closed contact 9, connected to the power circuit of the control circuit; KA2 relay coil 11, connected in series with micro switch 10 and connected to the control circuit; KA2 first normally open contact 61, KA2 second normally open contact 62 and KA2 third normally open contact 63; wherein, KA3 relay 7, including: KA3 first relay coil 13, connected in series with KA2 first normally open contact 61 and connected to the control circuit; KA3 second relay coil 12, connected in series with KA3 normally open contact 17 and KA2 second normally open contact 62 in turn and connected to the control circuit; KA2 third normally open contact 63, connected in parallel to KA3 normally open contact 17; human infrared induction sound and light alarm 8, connected in parallel to KA3 second relay coil 12. The control subsystem also includes: current relay KA15, connected to the wiring terminal of the regional maintenance power supply box. The PC host 1 is also provided with a sound and light alarm 2. The KA3 relay 7 is connected to the regional I / O substation 4 via PROFIBUS-DP communication, and the regional I / O substation 4 is connected to the edge WEB server 3 via PROFIBUS-DP communication.

[0012] When the present invention is in use, the PC slave 16 has a sub-administrator with the right to log in to the PC host 1. The PC host 1 and the PC slave 16 realize data exchange through the PROFIBUS-DP communication mode. When there is a temporary maintenance operation on the equipment and it needs to be shut down for maintenance, the operator needs to submit a temporary power application to the PC host 1. Taking the PC slave 16 administrator as an example, at this time, the PC slave 16 administrator needs to log in to the PC host 1 to submit a temporary power approval form. After submission, the system circulates according to the set approval flow. After the PC host 1 console completes the approval, it automatically issues the maintenance equipment. After the password of the electromagnetic lock on the maintenance power box in the preparation area is obtained from the PC slave 16, the maintenance power box can be opened, and the power end of the operating equipment is connected to the wiring terminal of the maintenance power box, and the operating equipment is powered. At this time, current passes through the current relay KA15, and the normally open point of the current relay KA1 is closed. The relay status is uploaded to the edge WEB server 3 through the I / O substation 4 in each area in the PROFIBUS-DP communication mode. The edge WEB server 3 communicates the status of each device to the PC host 1 to monitor the working status of the maintenance power box in each area.

[0013] When there is a temporary maintenance operation and the machine needs to be shut down for maintenance, in order to ensure the safety of the operators and prevent the equipment from starting suddenly and causing personal injury, the operator hangs the martensitic stainless steel lock 14 in the keyhole. The lock is attracted by the magnetic ball and relies on its own weight to drive the iron connecting rod 15 connected to the magnetic ball to move downward. The iron connecting rod 15 drops to the fixed point of the micro switch 10, thereby driving the handle of the micro switch 10 to move downward, so that the micro switch 10 is closed, the KA2 relay coil 11 is energized, and the KA2 normally closed contact 9 is disconnected, so that the equipment is powered off. The equipment cannot be started locally or remotely. At the same time, the KA2 first normally open contact 61 and the KA2 second normally open contact 62 are closed. The open contact 62 and the third normally open contact 63 of KA2 are closed, the second relay coil 12 of KA3 and the first relay coil 13 of KA3 are energized, the normally open contact 17 of KA3 is closed, and the human infrared sensing sound and light alarm 8 is energized and works. When a person enters the detection area within 5 meters of the human infrared sensing sound and light alarm 8, the human infrared sensing sound and light alarm 8 emits an alarm sound "The equipment is under maintenance, please pay attention to safety". The alarm information is uploaded to the edge WEB server through each regional substation via PROFIBUS-DP communication. The server communicates to the intelligent energy management and control platform to realize anti-intrusion area alarm monitoring in each area.

[0014] Among them, when there are illegal operations during non-working hours or forced operations without approval, the PC host 1 sends an alarm message through the sound and light alarm 2 based on the feedback information, "There are illegal operations during non-working hours in the XX area, please stop them in time" or "There are unauthorized illegal operations in the XX area, please stop them in time."

[0015] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
