Numerical control machining (numerical control machining) refers to a process method for processing parts on a CNC machine tool. The process regulations of CNC machine tool processing and traditional machine tool processing are generally consistent, but significant changes have also taken place. A machining method that uses digital information to control the displacement of parts and tools. It is an effective way to solve the problems of variable parts, small batches, complex shapes, and high precision, and to achieve high-efficiency and automated processing. Interpretation: Numerical control processing refers to the processing in which the control system issues instructions to make the tool perform various movements that meet the requirements, and expresses the shape and size of the workpiece in the form of numbers and letters, as well as processing requirements. It generally refers to the process of processing parts on CNC machine tools. A CNC machine tool is a machine tool controlled by a computer. The computer used to control the machine tool, whether it is a special computer or a general-purpose computer, is collectively called a CNC system. The movement and auxiliary actions of the CNC machine tool are controlled by the instructions issued by the CNC system. The instructions of the numerical control system are compiled by the programmer according to the material of the workpiece, the processing requirements, the characteristics of the machine tool, and the instruction format (numerical control language or symbols) prescribed by the system. The numerical control system sends out operation or termination information to the servo device and other functional components according to the program instructions to control various movements of the machine tool. When the part processing program ends, the machine tool will automatically stop. For any kind of CNC machine tool, if there is no program command input in its CNC system, the CNC machine tool

The most widely used street lamps in the construction of new rural areas should be led street lamps or solar street lamps. They are mainly energy-saving and can ensure the lighting effect. They can kill two birds with one stone. Use solar street lamps in remote mountainous areas or areas with relatively low power system coverage. It is the most wise to choose the object, because it has the lowest requirements for the surrounding conditions, it can illuminate as long as there is the sun, the least picky and the easiest to form street light products, and the most cost-effective one is the 6-meter solar street light. With hot sales and high penetration rate, let's talk about the reason and inevitability of it below. The price of conventional rural 30-watt 6-meter solar LED street lights is more than one thousand four yuan and less than one thousand eight yuan, and the corresponding configuration can basically meet all regions of the country. The price range is because of the different places of use and the different lighting time requirements , The quotation is not unique due to different rainy and cloudy conditions, and it needs to be customized. You can contact the manufacturer. Solar street light manufacturers discuss the practicality of 6-meter solar street lights. The first thing to consider when making solar street lights is the height of the light pole. The height of the light pole is determined by the width of the road where it is used, how many directions, whether there is auxiliary road, etc. It is said that basically four-way roads with auxiliary roads, so the natural road width must be more than ten meters, then the height of the light pole must be about 8-10 meters, and the auxiliary roads require solar street lights to be made of double arms. The arm is 80-100 watts, and the auxiliary arm is 30 watts, but if the basic road width in rural areas does not exceed 5 meters, this

health LED street lights are free of environmental pollutants such as mercury and lead, and will not pollute the environment. We know that mercury is an extremely toxic substance, but most of the high-efficiency electric light sources currently used contain mercury. According to the study of mercury by Stanford University in the United States, 1 mg of mercury is enough to pollute 5454.5 kg of drinking water. long life The LED light source has a long service life, with a service life of 5-10 times that of traditional lamps. Low carbon Bo Siwei Optoelectronics LED Street Light (120W) = Less use of 298 kg of standard coal per year = 1092 kg of CO2 less emissions per year saving The energy-saving rate of the LED (110W) street lamp of Broadway Optoelectronics is 63% compared with the high-pressure sodium lamp of 250W (system power 300W). It saves 762 kWh/year, which is about RMB 670. Calculated by 5 years of use, it can save electricity costs of 3350 yuan and save traditional lighting supplies by 300 yuan. For new roads, each LED street light can save about cable and transformer costs. 1830 yuan.

The solar LED street light system is an independent photovoltaic system, which consists of six parts: solar battery, battery, LED street light, charging circuit, discharge/drive circuit and controller. The battery is one of the important parts of the hybrid system in the solar LED street light system, so its remaining charge capacity (SOC) also has a significant impact on the stability of the system. The solar LED street lamp system is under the control of the controller. During the day, the solar battery charges the battery through the charging circuit, and the battery discharges at night to drive the LED street lamp, so the design of the controller is very important. If the battery is often over-discharged or over-charged, the battery life will be greatly shortened. In response to this problem, the segmented multi-point monitoring method can be used to monitor the charge/discharge method of the remaining charge capacity (SOC) of the battery. During the discharging process, just like the controller during the charging process, the segmented multi-point monitoring can be used in different Different widths of PWM signal output control are used in the different stages, which effectively avoids over-discharge. Finally, the hardware of the solar controller and the control software of the system are designed. When a large number of independent operation of solar LED street lights are used, it is necessary to know the operating status of each street light in time and accurately, so a networked solution based on CAN bus is designed. The design realizes the CAN bus hardware interface on the street lamp controller, and also realizes the host computer monitoring.

This also creates very good conditions for its future sustainable workability, which can effectively increase the working characteristics of its products to a certain extent, so that solar LED street lights can be more durable. When installing solar LED street lights, only guarantee LED The high efficiency of solar street lights can ensure the road to achieve good road lighting. Solar LED street lights are now more and more widely used in road energy-saving lighting. Because LED solar street lights are durable and energy-saving, they are relied on by government agencies or large enterprises in various countries, and LED solar street lights are used by street light manufacturers to reduce energy consumption. At the same time, the quality of road lighting is improved to ensure people's travel safety. The working principle of the solar street lamp is very simple, that is, the solar panel made by the photovoltaic special effect principle receives solar radiation energy during the day and converts it into electrical output. It is stored in the solar battery through the charge and discharge controller, and the illuminance gradually decreases to About 101ux, the open circuit voltage of the solar panel is about 4.5v. After the charge and discharge controller measures this voltage, the solar battery will discharge the lamp cap. Generally, the market price of

Products such as LED high-power floodlights can really shine in the lighting effect, and their own characteristics and practicality can also meet the needs of consumers. So how should the product be maintained when it is not normally used? The first step for maintenance is to turn off the power of the LED high-power floodlight. This is a step that all lamps must be maintained for maintenance. Because doing so can ensure that the entire maintenance process is safe, and will not harm the product's circuit. So turning off the power is a must. Secondly, when cleaning, be sure to wipe it with a dry cloth. Wipes soaked in water will often cause certain damage to lighting fixtures, for example, if water drops into the fixtures, if this happens, it is irreversible for this type of product. Therefore, during the cleaning process, there must be no water stains. It is worth noting that when cleaning, do not use chemical substances to wipe, such as detergent, etc. These chemical substances often have a corrosive effect on the surface of LED high-power floodlights. Therefore, the maintenance work needs to pay attention to many aspects. In fact, the whole work is not difficult. Proper treatment of some details can often make the maintenance work have the corresponding effect.

1. First check whether the controller battery indicator light is on, if not, check whether the connection line between the controller and the battery is off. If the connection line is normal, check the battery voltage with a multimeter. The battery voltage is normal and replace the controller. 2. Check whether the load indicator of the controller is on, and check the output voltage with a multimeter to see if there is a voltage output. If there is no voltage output, replace the controller. 3. Do photovoltaic modules need to face south? It is best to face the photovoltaic module to the south. In order to ensure that the module can receive as much and even as possible light radiation, when designing the module bracket, we have made the best tilt design according to the regional sunshine situation. 4. Is the solar panel fragile? The solar panels are composed of fairly strong toughened glass panels, all of which have passed the hail test. 5. How much electricity can solar street lights produce? Different configurations have different power generation and lighting duration. We will recommend or design a street light configuration that can meet your requirements according to your lighting requirements and local actual conditions. 6. What happens if the solar panels are shaded? Solar panels should be installed in a place where there is no shade and can receive sunlight all day long. Even a small amount of shading will greatly reduce the power output of the system. In the initial site selection for the installation of solar street lights, places with obstructions should be avoided. 7. Should I clean the solar panels frequently? Under normal circumstances, it is not necessary to clean the solar panels frequently. In most areas, there is enough rainfall to clean the panels. If it is in a dusty area, timely cleaning is a must. It can be cleaned with a hose. Be careful not to step on or walk on the sol

What factors influence the price of solar street lamps? First of all, we need to know what these factors are! So let's talk about what solar lamps are made of. A complete set of solar street lamps should be composed of: lamp pole, light source, photovoltaic panel (solar panel), battery, controller, base cage, wires and screws. Let's start with the solar lamp pole. The price of the lamp pole is affected by the height, wall thickness, arm length and molding process of the lamp pole. The higher the height of the lamp pole, the higher the price, wall thickness, arm length is proportional to the price of the lamp pole. In modeling, the most commonly used humanized arm, self-bending arm, conch arm and S-arm, among which the self-bending arm is on the low side and the conch arm and S-arm are on the high side. Light source yu liang, irradiation range Yu Wide, then its lighting power needs yu, the higher the lighting power price will be higher, the brand of light source chip on the price will also have a certain impact. Now let's talk about photovoltaic panels. At present, photovoltaic panels used by solar street lamps are divided into monocrystalline silicon solar panels and polycrystalline silicon solar panels. The photoelectric conversion rate of monocrystalline silicon solar panels is higher than that of polycrystalline silicon solar panels. Solar street lamp batteries are divided into colloidal batteries and lithium batteries, in the same power, the price of lithium batteries is more than 1 times the colloidal batteries, small power we recommend conditional customers choose lithium batteries, becaus
