The scope of use of the treasure detector is also very wide, because there are many manufacturers in the market to produce it, so the quality is also uneven. In order to allow users to buy a good quality treasure detector, the next step is to share with friends what you need to pay attention?

buy treasure detector need to pay attention to what?

When we see the treasure detector, we should know that it has a wide range of applications and many advantages. Many people in the industry are also used for these reasons. First of all, when buying a treasure detector, you must choose according to your own needs, so that you can buy products suitable for your occasion. In this way, the money will not be wasted and can play its practical role. If you still don't know how to buy it, you can come here and have a look.

Secondly, to find regular manufacturers to buy. When choosing a manufacturer, you need to see if it has strong strength. There are many on the market now, so users may be dazzled when choosing, and many advertisements will be seen on the Internet, so it is difficult for us to distinguish at this time. Which companies are good treasure detectors. At this time, you can see when they were established and what honors they won. Through these we can judge their strength. Moreover, consumers also need to see whether they have their own factories and whether they develop and produce independently. If not, it is OEM treasure hunting company, try not to choose.

In addition, if you want to buy a good quality treasure detector, you need to look at the reputation of the manufacturer you are looking for and whether its after-sales service is in place. Of course, what you need to know is that its reputation is the standard for any industry to measure manufacturers. Pre-sales is also a standard to determine whether a manufacturer is responsible. Some manufacturers only have pre-sale and no after-sale. In this case, they can only use their real names, which is irresponsible. If you buy treasure detectors through them, either the price is expensive or the quality is not guaranteed. In this way, the original effect will not be achieved, so it is not recommended to choose.

What is the design of the treasure detector control system?

Hardware Circuit Design of Treasure Exploration Control System

The control hardware circuit mainly includes the design of oscillation circuit, amplifier circuit, peak detection circuit, signal processing and alarm display circuit. Coil oscillation circuit. The pulse frequency is 24KHz and the duty cycle is 2/3.

2. Amplification and peak detection circuit. The voltage variable of the Hall element output is relatively small, and the voltage needs to be amplified first. The voltage output by the OH49E element is amplified by the amplifier circuit.

3. Alarm circuit. The alarm part of the treasure search is essential. There are many alarm methods for this product on the market. In this system, we use the buzzer and LED display alarm circuit. The input signal is the received microcontroller signal. The current limiting resistor in the alarm circuit should be suitable, which can not only protect the circuit, but also ensure that the current in the circuit is not too small to make the alarm not obvious.

4. Display circuit. In order to use conveniently, the system also designs the display part. The output of the AT89S52 is connected to a four-digit digital tube. The output port P0 determines the four digits, and the output port P2 determines the on/off of the eight segments of each digit. The voltage values in the circuit are shown above.

Software Design of Treasure Exploration Control System

In the rapid development of science and technology today, software shows a very important position. Software can better simplify the hardware circuit of the system, so as to improve the stability of the treasure hunting system. The data collected by the hardware is digital.

The treasure detector system has met the requirements, can detect nearby metals, and can let us know the detection results intuitively through the alarm device. In real life, it also has a certain practicality, overall more convenient, easy to carry and use. The shortcomings of this treasure detector system are also obvious. Its structure is a traditional way, which is very different from the way used today. It cannot detect the size, weight, shape, etc. of metal.
