OFweek smart home network: Today, smart sweeping robots have been in service in many families, it can be said that they can be considered in the field of household cleaning can be a single side. Today, the author wants to discuss with you about the automatic recharging of sweeping robots.
The automatic recharging of the sweeping robot continuously sends out signals through the charging base, and then the receiver at the top of the robot receives the signal and successfully locates it, thereby embarking on the “home†path. However, it is believed that many users have encountered the failure of the sweeper back-charge failure in actual use. Then, regardless of the quality of sweepers, what can we do when we encounter such situations?
How many kinds of automatic refilling technology for sweeper?
Sweeper's automatic back-fill technology, there are a variety of technical principles, of which the most important are infrared positioning, Bluetooth positioning and radar positioning 3 kinds. And these three kinds of positioning technology, each have their own advantages, let's look at it first!
Infrared positioning
Infrared positioning accuracy is high, so about 70% of models on the market use infrared positioning. However, the relatively weak link is that such light cannot penetrate the object, so that the infrared light can only be positioned within the line-of-sight range. Once it is shielded by the object, the signal connection between the base and the sweeper will be lost. Therefore, the sweeper works in a dusty environment, and some dust debris easily interferes with the infrared receiver on the body, causing the sweeper to fail to recharge.
Ultrasonic radar positioning
Ultrasonic radar positioning, which is bionic ultrasonic positioning technology, is mainly used to locate objects through reflective distance measurement. The principle is based on bats in reality. Ultrasonic radar positioning ranging is affected by multipath effects and non-line-of-sight propagation, and the production cost is high, but compared with infrared positioning, the resolution of black objects and transparent objects is relatively accurate.
Bluetooth technology
Bluetooth technology is positioned by measuring the strength of the model and its power is relatively low. In general, positioning systems made with Bluetooth are small in size and therefore ideal for integration into sweeper circuits. The biggest advantage of using this technology is that the device is small and easy to integrate into small smart devices. Of course, in addition to its advantages, Bluetooth technology also has its own inadequacies, that is, the manufacturing costs of Bluetooth devices and devices are relatively expensive, and for a complex space environment, the stability of the Bluetooth system is poor, and is interfered by noise signals. Large, so really not used in sweeping machine industry.
What should we do if the sweeper fails to recharge?
After understanding the principle and technology of the automatic refilling of the sweeper, then the question arises. When the sweeper fails to recharge, what can we do?
In fact, there are two cases in which the sweeper fails to recharge. One is that the sweeper cannot find the charging base, and the other is that the sweeper finds the charging base but cannot perform normal charging.
Can't find the base
Sweepers have been unable to find the base on the recharging road and are blindly slowing down, it really makes many users crazy, especially those who do not have a physical remote control, only the back button on the machine or only through the phone APP Controlled models. In addition, when the sweeper needs to be recharged, he or she is often insufficiently measured for its own power. Therefore, it is such a fear that the remaining power will be consumed on the way to “find a homeâ€.
There should be no debris in the front and both sides of the base within 0.5-1m.
Examine the environmental factors that affect the recharge. Sweeper can not find the base, the first thing to do is to check the environment placed on the charging base, in general, the charging base should be placed on an open and flat ground, close to the wall, away from a step or a gap Place, and do not have sundries within 0.5-1 meter in front and on both sides.
Determine if the charging base is malfunctioning. Place the sweeper at a distance of 1.5 meters from the charging cradle and manually activate the “auto-recharge†function of the sweeper to see if it can successfully return to the base. If not, move the sweeper directly to the base. Manually align the charging pole piece to see if it can be charged normally. If it can be charged, it means that the base signal device has malfunctioned and should be repaired.
Find the base but it does not charge properly
When the sweeper finds the base but cannot always charge normally, the most likely condition is contamination on the charger. At this time, use a rag to wipe both the charge base of the charging base and the sweeper.
There is also a situation where the author once had contact with a sweeper, but found that it is often repeated several times when returning to the charge, but at this time the author gently pushes it, it can be smoothly home and charge. Carefully observed, the original pole position of the charging base design is a bit too high.
So the author tried a small method, that is, the use of double-sided tape or transparent glue to help sweeping machine universal wheel into the base position slightly raised by about 1 mm, so that every time the sweeper back to the base can be very smooth once In place.
When the sweeper encounters a failure to return charge, we can generally try the following measures:
1. Check the environmental factors that affect the recharging (position of the base, indoor debris, whether or not there are electrical devices that generate interference signals near the base, etc.);
2. Use a dry cloth to clean the contacts of the charging base and the bottom of the cleaning robot that are in contact with the base.
3. Place the sweeping robot at a distance of 5 feet (about 1.5 meters) from the base. Start the sweeping robot and press the "Seated" button to see if the sweeping robot can successfully recharge the charger's seat. If not, you need to repair it.
4. Determine whether the sensor of the sweeping robot is working or not, start the sweeping machine, observe whether the obstacle will automatically avoid the obstacle, and if not, the sensor of the sweeping machine is faulty;
5. Check if the charger is damaged and check whether the charger indicator is steady green.
Summary of the article: As a smart home appliance that helps modern people to reduce their cleaning burden, the sweeping robot has user-friendly functions such as cleaning performance, appointment function, and automatic recharging function, so that users can no longer worry about home cleaning. However, once the automatic refill function of the sweeper becomes obstructed, this will greatly affect the normal use of the machine. So, if the sweeper in your home also has a failure to return charge, check it out carefully.
All-in-one Energy Storage System
An energy storage system (ESS) is a device or set of devices used to store energy for later use. ESSs can store energy in various forms, including chemical, mechanical, thermal, and electrical energy. The stored energy can be used to power homes, buildings, or vehicles, or to supplement the power grid during periods of high demand.
ESSs are becoming increasingly important as renewable energy sources such as solar and wind power become more popular. These sources of energy are intermittent, meaning they only produce electricity when the sun is shining or the wind is blowing. ESSs can help to smooth out these fluctuations in energy production and make renewable energy more reliable and cost-effective.
ESS is an integrated battery system that stores your solar energy for backup protection, so when the grid goes down your power stays on. Your system detects outages and automatically recharges with sunlight to keep your appliances running for days.GOOTU offers a modular, flexible design and can be easily customized to meet diverse customer needs.
