Description

Technical Field

[0001] The present invention relates to the technical field of smart grid, and in particular to a smart grid identification plate. Background Art

[0002] In power grid enterprises, safety, health and environmental protection signs (referred to as signs) are an important part of power infrastructure. Most signs are installed on poles or fixed components of transformer stations to indicate the name of the line, the voltage level, name, location, number, etc. of the equipment. At present, many signs on power facilities still use traditional old iron plates. After years of exposure to the sun and rain, such signs are prone to corrosion and rust. In addition, when reorganizing power infrastructure equipment, it is necessary to change the equipment, name, location and number on the sign, so such signs need to be replaced frequently.

[0003] The traditional way to replace signboards is to make a power outage plan for the replacement area in advance, and then go to the corresponding work site to replace them, which requires a lot of manpower and material resources, and the replacement will inevitably affect the normal power consumption of residents, reducing the reliability of power supply and customer satisfaction. In order to minimize the impact of power outages on residents, distribution operation and maintenance personnel need to replace them at night, but the light at night is dim, which is not conducive to the distribution operation and maintenance personnel to determine the location of the signboard that needs to be replaced, which will inevitably affect the speed of emergency repair and power restoration.

[0004] Providing a safety, health and environmental protection identification plate that is easy to replace identification information is a technical problem that technical personnel in this field need to solve. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to more clearly illustrate the embodiments of the present invention or the technical solutions of the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0020] Figure 2A control circuit diagram of a smart grid sign provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0021] The core of the present invention is to provide a smart grid identification plate, which is more convenient to replace identification information than traditional iron identification plates.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the 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.

[0023] Figure 1 A connection diagram of a smart grid identification plate provided by an embodiment of the present invention.

[0024] like Figure 1 As shown, the smart grid sign provided by the embodiment of the present invention includes a display module 101, a light intensity detection module 102, a wireless communication module 103, and a central processing module 104 connected to the display module 101, the light intensity detection module 102 and the wireless communication module 103 respectively;

[0025] The central processing module 104 controls the display module 101 to display the identification information received through the wireless communication module 103 , and adjusts the brightness of the display module 101 according to the ambient light information detected by the light intensity detection module 102 .

[0026] Traditional iron signboards have a single function and can only be used to identify simple information. The recycling rate is not high. After the reconstruction of the power equipment infrastructure, they cannot be updated in time and correspond to the modified design drawings in time. Timely updates often bring inconvenience to the workers who are working outside in checking the name, location, and number of the tower equipment. If it is high-voltage equipment, once the information is wrong, it will be carried out in the wrong work area, which often poses safety hazards and increases the risk of working outside. The traditional way to replace the signboard is to make a power outage plan before replacing the signboard on the tower. It often requires a lot of physical strength to climb up to the tower to replace it, which has certain operational risks.

[0027] Therefore, the embodiment of the present invention provides a signboard that can remotely change identification information, which meets the intelligent requirements of current smart grid technology. After the power facilities are changed or modified, the identification information of the signboard can be modified online in real time, without the need for distribution and maintenance personnel to go to the site to replace the signboard, saving a lot of manpower and material investment, reducing the production cost of the signboard in long-term use, and effectively reducing the risk of production operations. The central processing module 104 adjusts the brightness of the display module 101 according to the ambient light information detected by the light intensity detection module 102 to ensure that the identification information displayed on the signboard is clearly visible under any light conditions.

[0028] In a specific implementation, the display module 101 may specifically include a liquid crystal display screen connected to the central processing module 104 and a display screen light source connected to the central processing module 104. Further, the display screen light source may specifically use an LED backlight. Both the liquid crystal display screen and the LED backlight have the characteristics of low power consumption and strong anti-interference, which is beneficial to energy saving of the device.

[0029] The central processing module 104 adjusts the brightness of the display module 101 according to the ambient light information detected by the light intensity detection module 102. It can be a positive correlation adjustment or a negative correlation adjustment. The specific implementation plan aims to ensure that the display module 101 can display clearly, and the adjustment method is selected according to the material selected for the display module 101.

[0030] A negative correlation regulation method is adopted, and the central processing module 104 adjusts the driving current of the lighting circuit of the display module 101 according to the ambient light intensity detected by the light intensity detection module 102. The smaller the ambient light intensity, the larger the driving current used. When the ambient light intensity is higher than the preset value (corresponding to a clear day), the central processing module 104 does not apply the driving current.

[0031] By adopting a positive correlation adjustment method, the central processing module 104 adjusts the driving current of the lighting circuit of the display module 101 according to the ambient light intensity detected by the light intensity detection module 102. The greater the ambient light intensity, the greater the driving current used, thereby ensuring that the identification information displayed by the display module 101 is clearly visible during the day and not dazzling at night.

[0032] The wireless communication module 103 may specifically be a Wi-Fi communication module or a GPRS communication module.

[0033] The light intensity detection module 102 may use a detection circuit built with a photoresistor as the core to convert the ambient light signal into an electrical signal and send it to the central processing module 104 .

[0034] The central processing module 104 can use a single-chip microcomputer to build a control circuit, set a serial port for connecting to an external controller, and provide a 5V and 3V power supply interface to facilitate program downloading. The central processing module 104 also includes a storage module for storing the name, location, number, voltage level and other identification information of the smart grid sign, which can be remotely modified through a host computer or an intelligent terminal.

[0035] In order to extend the service life of the device and facilitate carrying and installation, the smart grid sign provided by the embodiment of the present invention may also include a sign body for carrying the display module 101, the light intensity detection module 102, the wireless communication module 103 and the central processing module 104. The sign body may be a rectangular box-shaped structure, the display of the display module 101 is embedded on the outer surface of the box body, and the internal circuit structures such as the light intensity detection module 102, the wireless communication module 103 and the central processing module 104 are encapsulated inside the box body.

[0036] Furthermore, the smart grid sign provided by the embodiment of the present invention may also include a detachable fixing member connected to the sign body. The structure of the detachable fixing member is designed based on the installation occasion of the sign.

[0037] The device that communicates with the smart grid sign through the wireless communication module 103 can be the host computer of the main station, or it can be a smart terminal carried by the staff (such as a mobile phone, tablet, etc.). When the identification information needs to be changed, the address number of the smart grid sign that needs to be modified is determined based on the host computer, and the content that needs to be modified is edited into a modification command. The modification command is remotely transmitted to the central processing module 104 of the smart grid sign on site through the wireless communication module 103. After the modification is completed, the central processing module 104 returns the modification success information to the host computer. If the host computer does not receive the modification success information beyond the preset time, it is determined that the modification has failed. After the modification operation is repeated and still fails to be modified successfully, the sign is remotely marked for on-site replacement.

[0038] The smart grid sign provided by the embodiment of the present invention comprises a display module, a light intensity detection module, a wireless communication module, and a central processing module connected to the display module, the light intensity detection module and the wireless communication module respectively; wherein the central processing module controls the display module to display the identification information received by the wireless communication module, and adjusts the brightness of the display module according to the ambient light information detected by the light intensity detection module. After the electric power facilities are changed or modified, the information of the sign needs to be consistent with the modified drawings. The smart grid sign provided by the embodiment of the present invention can realize real-time online modification of the identification information, and there is no need for the distribution operation and maintenance personnel to go to the site to remove and replace the sign, which saves a lot of manpower and material investment, reduces the cost of making the sign, and improves the economic benefits of the power grid enterprise. Even if the sign needs to be replaced, since the smart grid sign provided by the embodiment of the present invention can adjust the display brightness according to the ambient light, the identification information can be clearly displayed under any light conditions, and the distribution operation and maintenance personnel can quickly determine its location, which effectively speeds up the operation speed of the distribution operation and maintenance personnel.

[0039] The smart grid sign provided in the above embodiment can determine its position through the correspondence between the pre-recorded address number and the address, but this method is not convenient for locating its position on site, especially when the smart grid sign fails, its display module 101 no longer provides lighting function, which is even more inconvenient to locate. Therefore, based on the above embodiment, in another embodiment, the smart grid sign also includes a GPS positioning module connected to the central processing module 104.

[0040] The GPS positioning module, also known as the GPS locator, is a terminal with a built-in GPS module and a mobile communication module. It is used to transmit the positioning data obtained by the GPS module to a server in the cloud through the mobile communication module (GSM / GPRS network), so that the terminal location can be queried on a computer or mobile phone.

[0041] Through the GPS positioning module, distribution operation and maintenance personnel can quickly determine the location of the smart grid sign on site without having to search by address number, which improves the efficiency of replacement work.

[0042] To facilitate application in various occasions, based on the above embodiment, in another embodiment, the smart grid sign also includes a power module connected to the central processing module 104 .

[0043] The power module is used to supply power to the central processing module 104, the display module 101, the light intensity detection module 102, the wireless communication module 103, etc. In a specific implementation, the power module can be a photovoltaic power generation module, which can supply power and charge at the same time when there is sufficient sunlight, and supply power to the system when there is insufficient sunlight, thereby achieving uninterrupted power supply throughout the day without the need for an external power supply.

[0044] Figure 2 A control circuit diagram of a smart grid sign provided by an embodiment of the present invention.

[0045] Based on the above embodiments, the present invention provides a circuit diagram of a smart grid sign in a better real-time manner. Figure 2 As shown, the power module of the smart grid sign provided by the embodiment of the present invention is composed of a solar photovoltaic power generation panel, a convergence control box, a voltage stabilization and regulation circuit, a battery charging circuit, and a conversion circuit.

[0046] Among them, the current generated by the three solar photovoltaic panels is all converged to the convergence control box for aggregation, and divided into two branch outputs, one is the voltage stabilization circuit and the other is the charging circuit.

[0047] The voltage regulation circuit includes a pre-stage filter circuit (including capacitors C1 and C2), a voltage regulator module U1 (using a 7805 three-terminal voltage regulator integrated circuit), a post-stage filter circuit (including capacitors C3 and C4) and a voltage regulator diode D1. The load circuit including the central processing module 104, the display module 101, the light intensity detection module 102, the wireless communication module 103, etc. is connected in parallel to the two ends of the voltage regulator diode D1. The output of the confluence control box is subjected to pre-stage filtering, voltage stabilization and post-stage filtering, and after passing through the voltage regulator diode D1, a stable voltage can be output, which prevents the load circuit voltage from changing due to the change in the amount of electricity generated by the load circuit and the solar photovoltaic power generation panel, and ensures that the electricity generated by the solar photovoltaic power generation panel can be supplied to the load circuit with a better voltage quality.

[0048] The charging circuit includes an IGBT switch, a fast recovery diode DIODE, an inductor L1, a capacitor C5, a resistor R5 and a battery BT1. The base of the IGBT switch is connected to the central processing module 104. The central processing module 104 controls the inductor L1 to store and release energy by controlling the on and off of the IGBT switch, thereby amplifying the input voltage and charging the battery BT1.

[0049] The output ends of the above two branches are connected to a conversion switch K1, and the conversion switch K1 can be a relay. The coil of the relay is provided by the voltage processed by the voltage regulating circuit. When the solar photovoltaic power generation panel generates electricity normally, the voltage regulating circuit outputs voltage and the coil is energized. The relay is a normally closed switch when the coil is not energized. When the coil is energized, the relay switch is disconnected. At this time, the voltage regulating circuit and the charging circuit are disconnected, and the load circuit is powered by the electricity generated by solar energy; when the sunlight is insufficient, such as at night, the solar photovoltaic power generation panel no longer generates electricity, and the voltage regulating circuit has no output voltage, then the relay switch is closed, and the power of the battery BT1 supplies the load circuit.

[0050] The above is a detailed introduction to a smart grid sign provided by the present invention. The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referenced to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part description. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.

[0051] It should also be noted that, in this specification, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.
