Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to an automatic detection and distribution system for split-type charging piles. Background Art

[0002] As a new type of high-power fast charging equipment, the split charging pile consists of two parts: a power supply cabinet and multiple charging terminals. Compared with the integrated charging pile, the split design of the split charging pile has the advantages of flexible installation and higher safety; however, the split charging pile also has the trouble of installation; each terminal of the split terminal is equivalent to an independent charging device, and the startup and operation are completed independently by the split terminal, and the data exchange with the platform is also carried out as an independent terminal; but the split terminal needs the power cabinet to provide charging energy, and the power cabinet is a power distribution and distribution control device, so the split terminal must be bound with the split terminal that distributes power with the same power cabinet, and the power cabinet is used as a whole system to communicate data with the platform. When installing, the operation and maintenance installation personnel need to first confirm the connection between the split terminal and the power cabinet, and then number the split terminals, determine the IP address, MAC address, terminal location information, etc. of each number, and then bind and upload this information to the platform, and finally test and verify the correctness of the data information one by one. This series of operations increases the workload of operation and maintenance installation, and places high demands on the technical knowledge reserves of operation and maintenance installation personnel, raising the threshold for operation and maintenance installation personnel, rapidly increasing labor costs, and low installation efficiency. Therefore, a simple and easy-to-operate split charging pile installation method is urgently needed. Summary of the invention

[0003] Problem to be solved: A method for installing a split-type charging pile that is easy to operate.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a split-type charging pile automatic detection and distribution system, comprising a split-connected power supply cabinet and a split terminal, the power supply cabinet including a power supply cabinet master control, the power supply cabinet master control including an LMS device and a PWM input port, there are N PWM input ports, and the power supply cabinet master control is connected to a cloud platform through the LMS device; there are n split terminals, and n is less than or equal to N, each split terminal includes a terminal master control, the terminal master control includes a terminal network port and a PWM output port, the terminal network port is connected to the cloud platform through the LMS device, and the PWM output port is connected to the power supply cabinet master control through the PWM input port.

[0005] Preferably, light language signals are provided on the split terminal.

[0006] Preferably, a unique MAC address and a unique production serial number are stored on the network port chip of each split terminal.

[0007] Preferably, the method comprises the following steps:

[0008] Step 1: After the cables are connected, the LMS device inside the power supply cabinet communicates wirelessly with the cloud platform through 4G signals; the LMS device connects the main control of the power supply cabinet and the terminal network port of the split terminal through the network switch to form an internal network; the PWM output port of the split terminal is connected to the PWM input port of the power supply cabinet, and the port number of each split terminal corresponds to the installation number of each split terminal;

[0009] Step 2: Power on the split terminal. After powering on, the split terminal broadcasts the MAC address information to the LMS device through the terminal network port. This MAC address is a unique code that exists on the network port chip of each split terminal and cannot be changed. At the same time, the split terminal will send a PWM pull-up level signal to the power supply cabinet through the corresponding PWM output port, indicating that a split terminal is connected to the power supply cabinet and no charging QR code is assigned;

[0010] Step 3: After the power supply cabinet detects that there is an access signal at the PWM input port, it will read any MAC address information in the LMS device, and directly conduct one-to-one information exchange with the split terminal corresponding to this MAC address through this MAC address; after receiving the information exchange, the split terminal adjusts the duty cycle and frequency of the PWM output according to the information content to cooperate with the power supply cabinet to confirm the installation location information of the split terminal;

[0011] Step 4: After receiving the confirmation signal from the PWM input port, the power supply cabinet packages the production serial number, location number and other information of the split terminal received from the network port and sends it to the cloud platform via the LMS device using the 4G signal;

[0012] Step 5: After the cloud platform authorizes and confirms the information in step 4, it forwards the charging QR code information of the split terminal to the split terminal through the LMS device. After receiving the charging QR code information, the split terminal adjusts the signal output by the PWM output port to the heartbeat packet signal of the waiting charging state, and stops broadcasting the MAC address. At this point, the allocation of a split terminal is completed, and the matched split terminal will display the light language prompt waiting for charging. Repeat the above steps in this way to complete the allocation settings of all split terminals one by one. The entire split charging pile system has been allocated and set up, and n split terminals all display the light language prompt waiting for charging. After receiving all the light language prompts, the operation and maintenance personnel submit the order to complete the installation and configuration.

[0013] Compared with the prior art, the present invention provides an automatic detection and allocation system for split charging piles, which has the following beneficial effects: (1) The present invention uses the internal network of the split charging pile itself and the heartbeat alarm system of each split terminal, and the self-test system when powered on to automatically identify the production serial number and installation location of the split terminal for binding.

[0014] (2) Through the design of the present invention, the operation and maintenance installation personnel only need to install the charging pile equipment normally and connect the cables correctly, without having to perform tedious settings and a series of configuration operations; they only need to wait for the automatic test to pass after powering on, without the need to manually determine, bind, and verify information, thus saving a lot of labor costs and simplifying the installation process.

[0017] The technical solution in the embodiment of the present invention will be described below in conjunction with the accompanying drawings in the embodiment of the present invention:

[0018] As shown in the figure, the present invention includes a power supply cabinet 1 and a split terminal 3, and the split terminal 3 is provided with n numbers. The power supply cabinet 1 includes a power supply cabinet main control 11, and the power supply cabinet main control 11 is provided with an LMS device 12 and a PWM input port 13; the split terminal 3 includes a terminal main control 31, and the terminal main control 31 is provided with a terminal network port 32 and a PWM output port 33, the terminal network port 32 is connected to the LMS device 12, and the cloud platform 2 communicates with the terminal main control 31 through the LMS device 12, and the PWM input port 13 is correspondingly connected to the PWM output port 33 to realize internal communication between the power supply cabinet main control 11 and the terminal main control 31. When the split terminal 3 leaves the factory, the unique production serial number will be burned into the terminal master control BOOT program. Each split terminal 3 corresponds to a PWM input port 13, i.e., the installation location. The power supply cabinet 1 will bind the production serial number and installation location of each split terminal 3. The LMS device 12 will assign an independent IP address to the split terminal 3. Then the cloud platform 2 will redefine a charging code for each split terminal 3 according to the binding information and distribute it to each split terminal 3. When the LMS device 12 sends the charging code to the split terminal 3, it will also store the charging code in the power supply cabinet 1. The whole process does not require the operation and maintenance personnel to participate in the setting. You only need to wait for the light language information to confirm that the installation is complete.

[0019] In the power supply cabinet 1, there is an LMS device 12 connected to the power supply cabinet main control 11. The LMS device 12 can communicate with the cloud platform 2 externally through a network cable or a 4G / 5G signal, upload the real-time status and charging information of the charging pile, and receive instructions issued by the cloud platform 2; internally, it is connected to the split terminal 3 through the terminal network port 32, receives the charging information and status of each split terminal 3, and issues instructions to the split terminal 3.

[0020] The terminal main control 31 of each split terminal 3 has a PWM output port 33, which is connected to the PWM input port 13 of the power supply cabinet main control 11. There are N PWM input ports 13 on the power supply cabinet main control 11, and N is equal to or greater than n. The first split terminal 3 is connected to the first PWM input port 13, the second split terminal 3 is connected to the second PWM input port 13, and so on. The nth split terminal 3 is connected to the nth PWM input port 13. The power supply of the PWM output port 33 uses a separate isolated power supply as the power supply output to ensure the output distance of the PWM signal. The frequency and output duty cycle of the PWM output signal are adjustable and are adjusted by the terminal main control 31.

[0021] After the equipment is installed and powered on, each split terminal 3 will broadcast its own unique MAC address through the switch, and at the same time, the data of the PWM input port 13 will be pulled high to notify the power supply cabinet 1 that a split terminal 3 has been installed and connected; the power supply cabinet 1 reads a MAC address arbitrarily in the network through the LMS device 12, and confirms the information one-to-one with the split terminal 3 through this MAC address. The corresponding split terminal 3 receives the confirmation information transmitted by the network port at this time, and opens the PWM output port 33 for PWM communication while replying; at this time, the power supply cabinet 1 obtains a series of factory information such as the production serial number of the split terminal 3 through communication, and obtains the installation number of the split terminal 3 from the location of the corresponding PWM input port 13; after the power supply cabinet 1 packages this information and sends it to the cloud platform 2 through the LMS device 12, after being authorized by the cloud platform 2, the charging authorization QR code information is sent by the LMS device 12 to the split terminal 3. After receiving it, the split terminal 3 completes the confirmation information with the power supply cabinet 1 and the cloud platform 2, and the split terminal 3 stops sending the MAC broadcast, and sends the heartbeat PWM signal normally from the PWM output port 33 to complete the configuration process. At this time, the power supply cabinet 1 reads that other PWM input ports 13 still have new installation split terminals 3 applying for network access, and reads a MAC address again at random, repeats the above steps, and completes the configuration of a split terminal 3 again; after repeating this n times, all split terminals 3 are configured, n PWM output ports 33 all send heartbeat signals normally, and the switch no longer receives the broadcast MAC signal, the automatic configuration of all split charging piles is completed, and the light signal on the split terminal 3 shows waiting for charging, which is fed back to the operation and maintenance installation personnel to complete the installation.

[0022] The system of the present invention mainly comprises the following steps when in use:

[0023] Step 1: After the cables are connected, the LMS device 12 inside the power supply cabinet 1 communicates wirelessly with the cloud platform 2 via a 4G signal; the LMS device 12 connects the power supply cabinet master control 11 with the terminal network port 32 of the split terminal 3 through a network switch to form an internal network; the PWM output port 33 of the split terminal 3 is connected to the PWM input port 13 of the power supply cabinet 1, and the port number to which each split terminal 3 is connected corresponds to the installation number of each split terminal 3;

[0024] Step 2: After being powered on, the split terminal 3 broadcasts the MAC address information to the LMS device 12 through the terminal network port 32. This MAC address is a unique code that exists on the network port chip of each split terminal 3 and cannot be changed. At the same time, the split terminal 3 sends a PWM pull-up level signal to the power supply cabinet 1 through the corresponding PWM output port 33, indicating that a split terminal 3 is connected to the power supply cabinet 1 and no charging QR code is assigned;

[0025] Step 3: After detecting that there is an access signal at the PWM input port 13, the power supply cabinet 1 will read any MAC address information in the LMS device 12, and directly perform one-to-one information exchange with the split terminal 3 corresponding to the MAC address through the MAC address; after receiving the information exchange, the split terminal 3 adjusts the duty cycle and frequency of the PWM output according to the information content to cooperate with the power supply cabinet 1 to confirm the installation location information of the split terminal 3;

[0026] Step 4: After receiving the confirmation signal sent from the PWM input port 13, the power supply cabinet 1 packages the production serial number, location number and other information of the split terminal 3 received from the network port and sends it to the cloud platform 2 via the LMS device 12 by 4G signal;

[0027] Step 5: After the cloud platform 2 authorizes and confirms the information in step 4, it forwards the charging QR code information of the split terminal 3 to the split terminal 3 through the LMS device 12. After receiving the charging QR code information, the split terminal 3 adjusts the signal output by the PWM output port 33 to a heartbeat packet signal waiting for charging status, and stops broadcasting the MAC address. At this point, the allocation of a split terminal 3 is completed, and the matched split terminal 3 will display a light prompt waiting for charging. Repeating the above process in this way can complete the allocation setting of all split terminals 3 one by one. The entire split charging pile system has completed the allocation setting, and n split terminals all display light prompts waiting for charging. After receiving all the light prompts, the operation and maintenance personnel submit the order to complete the installation and configuration.

[0028] The above embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
