Description

Technical Field

[0001] The utility model relates to the field of transformer substation automation control, in particular to a field recoverable sequential control simulation device. Background Art

[0002] With the vigorous promotion of the one-button sequential control application by the State Grid, the verification of one-button sequential control in various places is in full swing. However, the sequential control verification process not only depends on the on-site working conditions, but also faces factors such as large workload and short construction period. Although domestic testing manufacturers have provided sequential control simulation devices to assist on-site staff to quickly complete the sequential control verification work, such devices often face unstable on-site power supply or system collapse due to improper operation of staff. If it is not serious, the manufacturer can remotely guide the on-site personnel to recover, but if it is serious, it must be returned to the factory for processing, which is not conducive to the orderly and rapid on-site sequential control verification work. Summary of the invention

[0003] The utility model provides a field recoverable sequential control simulation device, with a built-in recoverable solid state hard disk, in which a hidden area backs up the system environment, effectively solving the problem that the field sequential control verification work system is difficult to recover when it collapses.

[0004] In order to achieve the above technical purpose, the utility model adopts the following technical solutions:

[0006] The recoverable solid-state hard disk, high-definition touch screen and USB universal interface are all connected to the main control core processing module;

[0007] The system recovery monitor is connected to the recoverable solid state hard disk.

[0008] Furthermore, the main control core processing module uses an Intel i3 processor as a main CPU.

[0009] Furthermore, the recoverable solid-state hard drive adopts an Innodisk M.2 (S80) 3TO7 flash memory solid-state hard drive.

[0010] Further, the recoverable solid-state hard disk is divided into a hidden partition, a test data recording area and a sequential control system environment area;

[0011] The test data recording area is used to record the recorded data generated by the sequential control simulation device when performing sequential control experiments;

[0012] The sequential control system environment area is used to: install the operating system of the sequential control simulation device and the sequential control verification software;

[0013] The hidden partition is used to back up the contents of the sequence control system environment area that have been verified to be correct, so as to be used for timely recovery processing when the system environment of the sequence control simulation device collapses during on-site use.

[0014] Furthermore, the interface design of the recoverable solid-state hard disk includes: a gold finger connector J1 dedicated to M.2, chip capacitors C1, C2, C3, C4, C5, C6, C7, C8, a chip resistor R1, and a chip light-emitting diode D1;

[0015] Connected to the IO port of the main control core processing module through the gold finger connector J1, used to realize data communication between the main control core processing module and the solid state hard disk;

[0016] Chip capacitors C1, C2, C3, C4, C5, C6, C7, and C8 provide stable power supply and power decoupling for the solid-state drive;

[0017] The chip resistor R1 and the chip light emitting diode D1 are connected in series and connected to the IO pin of the main control core processing module.

[0018] Furthermore, the system recovery monitor includes an independently set MCU, an LED light, and a buzzer, and the LED light and the buzzer are all connected to the MCU; the MCU is used to monitor the working status of the system recovery process of the recoverable solid-state hard disk in real time, and output the system recovery progress by controlling the LED light, and prompt abnormalities in the system recovery process by controlling the buzzer.

[0019] Furthermore, the field-recoverable sequential control simulation device also includes a network card and a three-layer switching network unit; the network card is connected to the main control core processing module to expand the number of network ports; the three-layer switching network unit is connected to the network card to provide a three-layer routing function for the expanded network port.

[0020] Furthermore, the network card is connected to the main control core processing module via a PCIE interface.

[0021] Beneficial Effects

[0022] The utility model provides a field-recoverable sequential control simulation device, which has a built-in recoverable solid-state hard disk, and hides part of the space as a hidden area for backing up the factory sequential control simulation device system environment. At the same time, the remaining hard disk space is partitioned to separate the system environment operation area from the test record data area. In the event of a field system crash, the sequential control simulation device can be restored to the sequential control simulation device system environment by adopting a partition design method, without deleting the simulation test data that has been generated for verification, which effectively solves the problem of difficulty in recovery when the field sequential control verification work system crashes.

[0023] In addition, the on-site recoverable sequential control simulation device of the utility model has a built-in three-layer switching network unit, which can realize the three-layer routing function without relying on an external switch. When simulating the dispatching master station function, there is no need to modify the parameter configuration of the on-site remote motor, thereby ensuring the actual on-site operating environment.

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the detailed description of the embodiments of the present application provided below in conjunction with the drawings is not intended to limit the scope of protection of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application. The utility model is further described below in conjunction with the drawings.

[0029] This embodiment provides a field recoverable sequential control simulation device, such as Figure 1 As shown, it includes: a main control core processing module, a recoverable solid-state hard disk, a system recovery monitor, a high-definition touch screen, a USB universal interface, a network card and a three-layer switching network unit; the recoverable solid-state hard disk, the high-definition touch screen, the USB universal interface and the network card are all connected to the main control core processing module; the system recovery monitor is connected to the recoverable solid-state hard disk to monitor the working status of the recoverable solid-state hard disk; the three-layer switching network unit is connected to the network card through a PCIE interface to expand the number of internal network communications.

[0030] The main control core processing module uses the Intel i3 processor as the main CPU, which is mainly used to run the sequential control work software, realize the human-computer interface interaction function, display the verification result interface, generate verification reports, and perform data storage.

[0031] The core of the recoverable solid-state drive is the Innodisk M.2 (S80) 3TO7 flash solid-state drive (SSD), which is electrically compliant with the Serial ATA (SATA) standard and supports speeds up to the SATA III standard (6.0Gb / s). The hard drive can achieve on-site recovery of the operating system environment through simple operations. When the hard drive is actually used, the size of its hidden partition can be pre-set at the factory, and the existing system environment can be backed up to the hidden partition through dedicated backup software, which greatly facilitates the problem of difficult recovery when the system crashes during on-site use.

[0032] like Figure 2 As shown, the partition diagram of the recoverable solid-state hard disk mainly includes a hidden partition, a test data recording area, and a sequential control system environment area. The hidden partition can be set up according to the actual situation using special software. Once the setting is successful, it is invisible to the sequential control verification system; the test data recording area is used to record the record data generated by the sequential control simulation device during the sequential control experiment; the sequential control system environment area is mainly used to install the operating system and sequential control verification software. When the sequential control simulation device leaves the factory, the contents of the sequential control system environment area that have been verified to be correct are backed up to the hidden partition, which is convenient for on-site use. After the system environment collapses, it can be restored in time through simple operations. Since partition processing is used throughout the design process, even if the system environment is restored, it will not affect the previous test records.

[0033] like Figure 3 As shown, the recoverable SSD interface design includes M.2 dedicated gold finger connector J1, chip capacitors C1-C8, chip resistors R1-R5, and chip light emitting diode D1. 41, 43, 47, and 49 of the gold finger connector J1 are respectively connected to the IO port of the main control core processing module to realize data communication between the main control core module and the SSD; the chip capacitors C1-C8 are mainly used to provide stable power supply and power decoupling for the SSD. The chip resistors R1 and D1 are connected in series and connected to the IO pin of the main control core processing module. The chip resistors R2-R5 are reserved resistor positions.

[0034] like Figure 4As shown in the figure, the system recovery monitor uses an independent MCU inside to monitor the working status of the recoverable hard disk in real time through a given bare metal hard disk working status monitoring program, and prompts the progress of the system recovery by controlling the LED light, which is conducive to the on-site staff to understand the current system recovery status in time. At the same time, a buzzer output prompt is added. If an abnormality occurs during the system recovery process, it can be prompted by triggering a long buzzer.

[0035] The above embodiments are preferred embodiments of the present application. Ordinary technicians in this field can also make various changes or improvements on this basis. Without departing from the overall concept of the present application, these changes or improvements should fall within the scope of protection required by the present application.
