The control system of the intelligent sweeping robot is stored, calculated, and processed by various signals transmitted by the sensing system, and then issued instructions to the drive system to complete the prescribed actions such as the most basic sweeping. The control system is controlled by the main MCU, angular velocity sensor, LCD The controller, RAM, RTC and crystal oscillator are composed of MCU and CPU. In order to ensure the stable and accurate operation of program instructions, it is necessary to use high stability RTC and a variety of high-precision crystal oscillators. TXC crystal oscillator RTC product 9HT10 crystal oscillator, built-in 32.768K crystal oscillator , product The calibration is completed before leaving the factory, and the stability is good to ensure that the internal clock of the MCU is more stable and reliable. There is also an imported 7M24000023 crystal oscillator with a frequency deviation stability of 10 ppm. The frequency deviation during operation is low, ensuring the signal acquisition and program operation of the MCU and CPU. More precise.
Taiwan Crystal Technology TXC Crystal Oscillator launched these two models, which are very suitable for sweeping robots. The 7M24000023 crystal oscillator robot is very suitable for the control system MCU of sweeping robots. This crystal oscillator frequency is 24MHz chip crystal oscillator, load capacitance 12PF, and has an ultra-small size. Sheet metal package, size 3.2x2.5x0.7mm, and has high precision and high frequency stability, wide frequency output range (10MHz~64MHz), TXC crystal oscillator 7M series crystal oscillator has high reliability, can be used for automatic installation and reflow soldering , Green and environmentally friendly products, another TXC crystal oscillator 9HT10 series crystal oscillator is suitable for the clock chip of the sweeping robot. This 9HT10 crystal oscillator has a frequency of 32.768KHz and a size of 3.2x1.5x0.75mm SMD metal surface package. The load capacitance is 7PF, 9PF, 12.5PF, you can choose, 7M24000023 crystal oscillator and 9HT10 crystal oscillator have passed RoHS certification, which is very suitable for wireless communication, sweeping robots, wearable smart devices, smart home, smart medical, WLAN, digital TV and other electronic products.
In the sweeping robot, the consistency of the communication frequency between the MCU and the acquisition unit and the execution unit is ensured to achieve rapid frequency capture, synchronization and data communication. A higher-precision crystal is required. The recommended accuracy is ±10ppm (this is the highest accuracy of ordinary crystals) , The low temperature drift ensures that the sweeping robot is not affected by the environment, and can stably establish connections and realize networking. The lower the value, the better. It is recommended to choose within ±20ppm. 7M24000023 crystal oscillator and 9HT10 crystal oscillator are mature in the market Application design, product performance is reliable, can greatly save PCB board space, is conducive to product miniaturization design, Jiake Electronics stocks in large quantities, has long-term stock supply, and can quickly support samples and mass production services.
