The wireless transmitting and receiving module is engaged in applications such as digital audio wireless transmission, digital video wireless transmission, wireless data communication, wireless transmission system, wireless remote control and telemetry system, wireless data acquisition system, wireless network, wireless security system, etc. Design has always been a bottleneck for wireless applications. The wireless transceiver module integrates the functions of the high-frequency keying transceiver circuit, and realizes the function of high-speed data transmission with an ultra-small volume and a lower cost.
With the improvement of smart home living standards, wireless transmitter and receiver modules are widely used in various electric screens, electric doors and windows, smart home control, smart home security and other places. Although it is just a small module, it plays a role that cannot be underestimated. Wireless transmitter modules are more and more widely used in various industries. Why is the wireless transmitter module used so widely? What is the function of the wireless transmitter and receiver module? The following editor will introduce it to you.
Function 1. It is used to form a wireless communication network with a star topology.
And it must be a multi-point star topology, and some extraordinary places require wireless communication. On the one hand, the price of such transmitting and receiving modules is low, and the cost of forming a star topology is relatively low;
On the other hand, this transmitting and receiving module can adopt a modular design, which is small in size, easy to use and easy to integrate. This transmitter and receiver module is very practical for wireless networks with low communication speed requirements and relatively short distances.
Function 2. It is used for wireless multi-channel (parallel) control.
Such as complex remote control robots, etc., some places require multi-channel (parallel) control. One method is to use the receiving module to directly connect to the decoder, and then connect it to electronic components such as relays to drive the subsequent controlled objects;
Another method is to use the receiving module to connect with the single-chip microcomputer. After the data is processed, the single-chip computer is used to connect the electronic components such as relays to drive the subsequent controlled objects. Usually, a pair of transmitter and receiver modules can realize six parallel wireless control. If the required number of channels is greater than six, multiple pairs of transmitter and receiver modules can be used to work at the same time to meet the actual needs.
Function 3. It is used for universal serial port (RS232 wireless data transmission.
Usually, many control instruments and devices use serial ports, and communication with these devices must meet the serial port requirements. Some extraordinary places, industrial control sites. When the wireless transmission method must be used, the transmitting and receiving modules mentioned in this paper can be selected naturally.
However, it must be explained here that to adopt this communication method, the corresponding software must be compiled at the transmitter and receiver to realize the file format conversion, so as to achieve the purpose of wireless communication. If the communication system is full-duplex, you can It is realized by using two pairs of shooting and receiving modules to work at the same time.
The above content is an introduction to the function of the wireless transmitter and receiver module. When choosing a wireless transmitter module, users must pay attention to whether their products are used in a more complex environment or a simpler environment, and the service life of the product. . If the product has good stability and consistency, a super-heterodyne wireless transmitter module must be selected. If the user's product has a short life cycle, such as remote control toys, motorcycle alarms and other low-cost products, in order to save costs, a super-regenerative wireless transmitter module can be selected.
