Industrial routers generally have higher stability than civilian wireless routers on the market, and they need to adapt to continuous operation in harsh weather conditions, and the cost is also higher. Nowadays, they are widely used in M2M industries in…

What is a VPN? VPN (Virtual Private Network) is a well-known abbreviation among regular Internet users. Initially, VPNs were used in enterprises to connect networks securely. Currently, VPN is used by the industrial IoT industry to encrypt data transmission environments.…

We should all know about antennas. Any radio communication system is inseparable from the composition of antennas. We all know that antennas are used to radiate and receive electromagnetic waves. Antennas can make a wireless transceiver device receive and transmit…

With the continuous development and maturity of sensors, wireless data transmission equipment, and application solutions, they are also constantly promoting the development of industrial applications, smart homes, smart security, smart transportation, smart environmental protection, smart agriculture and other industries; recently,…

As an execution amplification and expansion component of signal output, the intermediate relay plays an important role in the automatic control system. According to the regulations of the equipment periodic inspection system, necessary inspections and tests should be carried out…

On September 12, 2019, Japan’s Environment Minister advocated that Fukushima nuclear wastewater be discharged into the sea Japan postpones decision to discharge Fukushima nuclear wastewater into the sea on October 24, 2020 Japan’s nuclear wastewater reserves are about to reach…

BLE is a low-power Bluetooth technology that can effectively reduce the power consumption of Bluetooth devices and increase the operating time of the device. But even the same BLE device will produce different power consumption rates under different usage conditions.…

This paper describes the interference phenomenon caused by using relays to control power loads in electronic circuits, analyzes the mechanism of interference and proposes solutions. The study found that the interference comes from spatial coupling, and the interference source is…

Generally speaking, we call the implementation code of a certain protocol a protocol stack. The Bluetooth protocol stack is the code that implements the low-power Bluetooth protocol. Understanding and mastering the Bluetooth protocol is a prerequisite for implementing the Bluetooth…

Zigbee is a wireless technology similar to Wi-Fi and Bluetooth, based on the 802.12 standard of the Institute of Electrical and Electronics Engineers (IEEE) standards association. Wi-Fi can transmit a lot of data at high speeds, while Zigbee mainly transmits…

The Zigbee protocol stack structure is composed of a series of protocol blocks called layers. Each layer provides a specific set of services to the layer above. The data portal provides data transmission services, and the management portal provides all…

The wireless transceiver module is the wireless transmitting module and the wireless receiving module. The two must be paired and used, and the operating frequency must be exactly the same. The receiving module must be equipped with a decoding IC…
