[0016] Figure 2 It is a structural schematic diagram of a multifunctional power supply control system of the present invention. DETAILED DESCRIPTION

[0017] A multifunctional power supply control system of the present invention is explained and illustrated in detail below in conjunction with the accompanying drawings of the specification.

[0018] like Figure 1-2As shown, the embodiment of the present invention discloses a multifunctional power supply control system, including a control module 1, a monitoring module 2, a communication module 3, an output management module 4, an emergency battery management module 5 and an emergency battery module 6. Among them, the control module 1 is electrically connected with the monitoring module 2, the communication module 3, the output management module 4 and the emergency battery management module 5, forming a path for data transmission and command issuance; the emergency battery module 6 is electrically connected with the output management module 4 and the emergency battery management module 5 respectively, to ensure the stable supply of electricity in an emergency situation. The control module 1 is used to receive the input power supply 7 operation data uploaded by the monitoring module 2, and the power equipment feedback data uploaded by the communication module 3. Based on these data (i.e., the input power supply 7 operation data uploaded by the monitoring module 2, and the power equipment feedback data uploaded by the communication module 3), the control module 1 can control the output power of the output management module 4, realize the switching between the input power supply 7 and the emergency battery module 6, and effectively control the power supply and disconnection of the power equipment. The emergency battery management module 5 controls the charging and discharging process of the emergency battery module 6 to ensure that the emergency battery is always available. The control module 1 can adopt a DSP (Digital Signal Processing) digital signal processor, an FPGA (Field-Prog rammable Gate Array) field programmable gate array, an MCU (Microcontroller Unit) system board, a SoC (system on a chip) system board or a PLC (Programmable Logic Controller) minimum system including I / O. In order to enhance the real-time, high-speed, anti-interference and reliability of the communication between the power-consuming equipment and the control module 1, the communication module 3 can adopt a CAN communication module. The monitoring module 2 can be a power quality analyzer. The emergency battery management module 5 can be a BCM or a BMS. The emergency battery module 6 can be a battery pack. The input power supply 7 is a mains power supply.

[0019] The power control system can not only realize the unified control of power supply and power off of various electrical equipment, but also reasonably allocate electric energy according to the actual power demand and operating status of the equipment. The emergency battery can be reasonably charged and discharged to extend the service life of the power supply, realize the efficient use of the power supply, and avoid unnecessary waste of electricity. At the same time, the communication module 3 adopts a standardized interface and a unified protocol, which effectively solves the problem of high system complexity caused by different control interfaces and protocols of various devices. Technicians no longer need to worry about complicated interface and protocol specifications, which greatly reduces maintenance costs. In the event of a fault, the problem can be quickly located and repaired with the help of a simple architecture, which effectively guarantees the stable operation and continuous service of the power supply.

[0020] Furthermore, the power-consuming devices are divided into AC power-consuming devices and DC power-consuming devices, and both the AC power-consuming devices and the DC power-consuming devices can feed back the power demand data to the control module 1 through the communication module 3. The control module 1 reasonably allocates output power to the AC power-consuming devices and / or the DC power-consuming devices according to the power demand data and the preset device priority through the output management module 4, thereby meeting the power demand of different devices and optimizing the power allocation efficiency.

[0021] It is worth noting that the AC power-consuming devices and DC power-consuming devices in the system are both set to multiple, and accordingly, the output management module 4 is configured with multiple power supply interfaces, and these power supply interfaces correspond to the numerous AC power-consuming devices and DC power-consuming devices one by one. The output management module 4 can accurately allocate the corresponding output power to each power-consuming device through the corresponding power supply interface according to the power demand data, thereby ensuring the accuracy and stability of the power supply.

[0022] The output management module 4 specifically includes a first control switch 41, a second control switch 42 and a third control switch 43. The first end of the first control switch 41 is electrically connected to the input power supply 7, and the second end is electrically connected to the AC power device; the first end of the second control switch 42 is electrically connected to the emergency battery management module 5, and the second end is electrically connected to the AC power device; the second ends of the first control switch 41 and the second control switch 42 are both connected to the DC power device through the AD conversion module; the first end of the third control switch 43 is electrically connected to the emergency battery module 6, and the second end is connected to the DC power device. The control module 1 can accurately control the on and off states of the three control switches, thereby realizing flexible switching of power sources and power distribution.

[0023] When the control module 1 determines that the input power supply 7 is supplying power normally, it will turn on the first control switch 41 and disconnect the second control switch 42 and the third control switch 43. At this time, the control module 1 accurately controls the input power supply 7 to provide corresponding output power for AC power equipment and DC power equipment according to the power demand data, thereby ensuring stable and efficient power supply.

[0024] On the contrary, when the control module 1 determines that the input power supply 7 is abnormal, it will quickly turn on the second control switch 42 and the third control switch 43, and disconnect the first control switch 41. Then the control module 1 will control the emergency battery module 6 to provide corresponding output power for AC power equipment and DC power equipment according to the power demand data, so as to ensure the continuous operation of key power equipment in emergency situations.

[0025] In addition, the multifunctional power supply control system of the present invention is also equipped with a main power supply switch 9, a first end of which is electrically connected to the input power supply 7, and a second end of which is electrically connected to the first end of the first control switch 41 and the emergency battery management module 5, respectively, which plays the role of the main control power supply access and enhances the safety and controllability of the system.

[0026] At the same time, the second end of the main power switch 9 is also electrically connected to the emergency battery management module 5, realizing the linkage between the power state and the emergency battery management module 5. When the input power supply 7 is supplying power normally, the emergency battery management module 5 controls the emergency battery module 6 to charge and reserve energy for possible emergency situations; when the input power supply 7 is supplying power abnormally, the emergency battery management module 5 controls the emergency battery module 6 to discharge and ensure uninterrupted power supply.

[0027] Furthermore, the system further comprises an alarm display module 8, which is electrically connected to the control module 1. When the control module 1 determines that the input power 7 is abnormal, the control module 1 will promptly transmit the alarm information to the alarm display module 8 for display, so that the operator can quickly detect the power abnormality and take corresponding measures, thereby improving the reliability and maintainability of the system.

[0028] Finally, it should be noted that the power supply operation data mentioned above covers at least one key parameter such as power supply power, power supply voltage and power supply frequency. These data provide an important basis for the accurate decision-making of the control module 1, and further ensure the stable operation of the entire multi-functional power supply control system.

[0029] The basic operating principle of the present invention is as follows:

[0030] In the integrated power supply control system, the monitoring module 2 monitors the input power supply 7 and transmits the monitored power supply operation data to the control module 1. If the input power supply is abnormal, the control module 1 transmits the prompt and alarm information to the alarm display module 8 for output. The power-consuming equipment uploads the power demand to the control module 1 through the CAN communication module 3, and the control module 1 adopts hierarchical supply according to the priority of the power-consuming equipment. In an emergency state, the power supply is switched to the emergency battery module 6. The priority hierarchical supply can more efficiently utilize the power of the emergency battery module 6 and ensure a longer power supply in an emergency state.
