　　If the mobile phone uses GPRS DTU on the Internet, data can be sent and received in groups, which means that users are always online and charged according to traffic, which quickly reduces the service cost. If CSD bearer is changed to GPRS, it means that dozens of people will bear the cost of the original one. Therefore, many unnecessary expenses will be greatly reduced.As it happens, many people are killed Wireless Module And bring more benefits, make it flourish, and promote the industry greatly. https://www.hkulike.com/

　　The advantage of GPRS DTU is that its data transmission speed is not comparable to that of GSM. At present, the transmission speed of GSM mobile communication network is 9.6K kilobytes per second, and the transmission speed of GPRS mobile phone has reached 56Kbps when it was launched at the beginning of this year, and now it has reached 115Kbps. Packet is to package Data into many independent packets, and then send these packets one by one, which is somewhat similar to sending a package. The advantage of packet switching is that it only takes up bandwidth when there is data to be sent, and it can be priced according to the amount of data transmitted, which is a more reasonable charging method for users, because most of the time and bandwidth of data transmission like the Internet are intermittent.

　　GPRS DTU can provide four different coding methods, which also provide different error protection capabilities. Using four different coding methods, each time slot can provide different transmission rates. Each user can use up to eight time slots at the same time. So GPRS DTU is called high transmission rate.

　　The wireless transceiver module is mainly used for signal transmission to achieve multi-functional purposes such as communication and wireless control. General wireless modules are used in a variety of occasions, and the following mainly introduces three kinds.In order to open the market, radio Module Constantly improve the ability of business development and create an extraordinary brand image for it. https://www.hkulike.com/

　　First, used for channel control

　　What is channel control? Channel control is divided into parallel and multi-channel. This kind of control is generally applied to the control of complex remote-controlled robots, and the safety protection control of some places can be controlled and driven by the receiving and sending signals of wireless modules.

　　Second, for the development of wireless communication networks

　　For professionals, the link of wireless communication network needs the application of topological structure, and only with this structure can the application value be realized by using the transceiver system of wireless module. On the one hand, this kind of transmitting and receiving module is cheap, and the cost of forming a star topology is relatively low; On the other hand, the transmitting and receiving module can adopt modular design, which is small in size, convenient to use and easy to integrate. This transmitting and receiving module is very practical for wireless networks with low communication speed and close distance.

　　Third, used for serial data transmission

　　Usually, many control instruments and devices use serial port, and communication with these devices must meet the requirements of serial port, and the transmission rate and electrical characteristics must meet the serial port standard. Some special places, industrial control sites. When it is necessary to use wireless transmission mode, the transmitting and receiving module mentioned in this paper can be naturally selected. However, it must be explained here that in order 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.

　　The JZX811A/B ad hoc network module of Techno Core adopts LoRa spread spectrum technology, and its working frequency is integrated with 433MHZ and 490MHZ. Simply setting the channel can complete the conversion of working frequency, which greatly meets the requirements of various application environments and improves the anti-interference ability of the communication system.As can be seen from the new data, radio Module The market influence is also growing, and the product share is also relatively increasing, which has great potential in the future. https://www.hkulike.com/

　　Ad hoc network is a planar peer-to-peer mesh network, and each node in the network can be used as a routing node and a target node. The communication module adopts the company’s self-organizing network protocol, making full use of the redundant routing in the network, and each node has multiple backup paths besides the main path; The network has good self-healing. When the access link between a node and the center fails, the center can automatically start the path repair function of the node.

　　The JZX811 networking network is composed of a coordinator JZX811B(Coordinator) and several nodes JZX811A(Router), and its system structure is shown in the following figure:

　　As we all know, wireless modules have two common performances. The following small series with outstanding skills will introduce the comparison of the two performances.Through bit by bit efforts, let RF Module Our market share is getting higher and higher, and the return on investment is also rising steadily. https://www.hkulike.com/

　　Firstly, the instantaneous frequency of the FM carrier transmitted by the FM transmitter is that the FM wave that changes with the modulation signal is an equal amplitude wave, and its maximum power is equal to the average power; The amplitude modulation transmitter emits an amplitude signal, and the maximum transmission power is equal to 4 times the average power. If the last stages of AM transmitter and FM transmitter use the same type of power tubes, and both are estimated according to the maximum power, the power emitted by FM transmitter is four times the average power emitted by FM transmitter.

　　The main feature of FM is its strong anti-jamming performance. The so-called strong anti-jamming performance mainly means that the signal-to-noise ratio at the output of FM receiver is greater than the signal-to-noise ratio at the output of FM receiver under the same input signal-to-noise ratio.

　　The reason why FM has stronger anti-jamming ability than AM can be analyzed from the power of the transmitted signals of the two systems. The power of the side frequency component of FM wave is divided from the carrier power. Its sidebands are not only numerous, but also increase in amplitude, which means that the proportion of power converted into sidebands in carrier rate is large, and the maximum power of sidebands of amplitude-modulated waves is equal to that of carrier power. Therefore, FM has more side frequency power than AM, which means it is more capable of overcoming the noise and interference in the channel or the machine.

　　Secondly, we can make a comparative analysis from the mediation of receiving signals. Because the information of amplitude modulation signal is contained in the amplitude of the amplitude modulated signal, the demodulated envelope detector can’t suppress the parasitic amplitude modulation interference, while the information of FM signal contains the frequency change at the moment of high frequency oscillation, so the parasitic amplitude modulation caused by interference can be removed by limiter.

　　Therefore, the anti-interference performance of FM system is better than that of AM system, regardless of the sideband power of the transmitted signal or the demodulation of the received signal.

　　The most basic usage of GPRS DTU is: put a SIM card with GPRS function in DTU, after DTU is powered on, first register to GPRS network, and then establish connection with data processing center through GPRS network. After the GPRS DTU is powered on, first read the working parameters saved in the internal FLASH (including GPRS dialing parameters, serial baud rate, IP address of data center, etc., which have been configured in advance).According to related reports, RF Module To a large extent, it leads the changes of market conditions. https://www.hkulike.com/

　　GPRS DTU logs into GSM network, and then dials GPRS PPP. After successful dialing, GPRS DTU will get an internal IP address randomly assigned by Mobile. That is to say, GPRS DTU is in the mobile intranet, and its intranet IP address is usually not fixed and changes with each dial. We can understand that GPRS DTU is a mobile device in the internal LAN, and it communicates with the external Internet public network through the mobile gateway. This is similar to the way that computers in a local area network access external networks through gateways.

　　GPRS DTU actively initiates communication connection with data center, and keeps communication connection always existing. Because GPRS DTU is in the mobile intranet and the IP address is not fixed. Therefore, only GPRS DTU can actively connect to the data center, but not the data center. This requires the data center to have a fixed public IP address or a fixed domain name. The public IP address or fixed domain name of the data center is stored as a parameter in the GPRS DTU, so that once the GPRS DTU is powered on and dialed successfully, it can actively connect to the data center.

　　Specifically, GPRS DTU sends TCP or UDP communication requests to the data center through the IP address and port number of the data center. After receiving the response from the center, GPRS DTU thinks that the handshake with the center is successful, and then keeps this communication connection. If the communication connection is interrupted, GPRS DTU will immediately shake hands with the center again.

　　Since the TCP/UDP communication connection has been established, two-way data communication can be carried out.

　　For DTU, as long as the two-way communication with the data center is established, it is relatively simple to complete the conversion between user serial data and GPRS network data packets. Once receiving the user’s serial data, DTU immediately encapsulates the serial data in a TCP/UDP packet and sends it to the data center. Conversely, when DTU receives the TCP/UDP packet from the data center, it takes out the data content and immediately sends it to the user equipment through the serial port.

　　Through the wired data acquisition center, it communicates with many GPRS DTU in two directions at the same time. This is the most commonly used way in GPRS DTU application system at present.

　　If the mobile phone uses GPRS DTU on the Internet, data can be sent and received in groups, which means that users are always online and charged according to traffic, which quickly reduces the service cost. If CSD bearer is changed to GPRS, it means that dozens of people will bear the cost of the original one. Therefore, many unnecessary expenses will be greatly reduced.Without exception, RF Module Our customers are willing to purchase their products, because high quality is the concept of their products. https://www.hkulike.com/

　　The advantage of GPRS DTU is that its data transmission speed is not comparable to that of GSM. At present, the transmission speed of GSM mobile communication network is 9.6K kilobytes per second, and the transmission speed of GPRS mobile phone has reached 56Kbps when it was launched at the beginning of this year, and now it has reached 115Kbps. Packet is to package Data into many independent packets, and then send these packets one by one, which is somewhat similar to sending a package. The advantage of packet switching is that it only takes up bandwidth when there is data to be sent, and it can be priced according to the amount of data transmitted, which is a more reasonable charging method for users, because most of the time and bandwidth of data transmission like the Internet are intermittent.

　　GPRS DTU can provide four different coding methods, which also provide different error protection capabilities. Using four different coding methods, each time slot can provide different transmission rates. Each user can use up to eight time slots at the same time. So GPRS DTU is called high transmission rate.

　　The working frequency of the wireless transceiver module is 315MHz or 433MHz (there are other special frequencies), and the SAW resonator is used to stabilize the frequency, so the frequency stability is extremely high. When the ambient temperature changes between-25 and+85 degrees, the frequency drift is only 3ppm/ degree. It is especially suitable for wireless remote control and data transmission system. The frequency stability of acoustic resonator is second only to that of crystal, but the frequency stability and consistency of general LC oscillator are poor. Even if high-quality fine-tuning capacitors are used, it is difficult to ensure that the tuned frequency points will not shift due to temperature difference and vibration.This shows that, Wireless Module It has a strong development pulse and is an indispensable source of power for the development of the industry. https://www.hkulike.com/

　　So how to use the wireless transceiver module correctly? The following small series of Zhuoxin Technology introduces the following three methods.

　　1. It is used to build a wireless communication network with star topology.

　　It must be a multi-point star topology, and some special places need wireless communication. On the one hand, this kind of transmitting and receiving module is cheap, and the cost of forming a star topology is relatively low; On the other hand, the transmitting and receiving module can adopt modular design, which is small in size, convenient to use and easy to integrate. This transmitting and receiving module is very practical for wireless networks with low communication speed and close distance.

　　2. Used for wireless multi-channel (parallel) control

　　Such as complex remote control robots, some places need multi-channel control. One method is that the receiver module is directly connected to the decoder, and then connected to electronic components such as relays to drive the subsequent controlled objects; Another method is to connect the receiving module with the single chip microcomputer, and then connect the relay and other electronic components with the single chip microcomputer after data processing to drive the subsequent controlled objects. Usually, a pair of transmitting and receiving modules can realize six parallel wireless control at most. If the number of channels required is more than six, multiple pairs of transmitting and receiving modules can be used to work at the same time to meet the actual needs.

　　3. Used for universal serial port (C502B) wireless data transmission.

　　Usually, many control instruments and devices use serial port, and communication with these devices must meet the requirements of serial port. Some extraordinary places, industrial control sites. When it is necessary to use wireless transmission mode, the transmitting and receiving module mentioned in this paper can be naturally selected. However, it must be explained here that in order 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, two pairs of transmitter and receiver modules can be used to work at the same time.

　　Of course, there are some precautions when using the wireless transceiver module. The transmitting module should be installed vertically on the edge of the motherboard, and should be more than 5mm away from the surrounding devices to avoid being affected by the distribution parameters. The transmission distance of wireless transceiver module is related to modulation signal frequency and amplitude, transmitting voltage and battery capacity, sensitivity of transmitting antenna and receiver, and receiving and transmitting environment.
