< .Product Introduction
B (r) is a wireless data transmission terminal using high reliability R processor and transparent.
Data transmission based on the public network has the characteristics of wide communication range, stable and reliable transmission, etc. B has been widely used in fields such as unattended, remote equipment monitoring, remote data collection, remote meter reading and remote dispatching. Since this product is specially designed for industrial integration, it adopts special designs in terms of temperature range, vibration, electromagnetic compatibility and interface diversity to ensure working stability in harsh environments and provide data communication for your equipment. High quality assurance.
To provide different customized terminals according to user requirements in different industries, this requires hardware, software development and system integration based on industry characteristics. The channels of mobile data networks can provide connections and can be used for applications such as R connections and data transmission. The B(r) data terminal unit is a wireless device specially used to transmit serial port data through the mobile data network.
This product is aimed at applications in power system automation, industrial monitoring, traffic management, meteorology, environmental protection, pipe network monitoring, finance, securities and other industry sectors. Taking into account the networking needs of each application department, it is implemented on the network structure Virtual data private network. It is suitable for the transmission of small and medium-sized data amounts from the center to multiple points and dispersed points.
B can easily connect and communicate with our company's B network converter.
< .Product Features: Standard industrial-grade products, anti-interference design, strong adaptability to the environment, independent research and development, embedded bit R embedded chip with real-time operating system, providing a variety of reset mechanisms, software controlled, achieving perfect The working frequency of the industrial security mechanism is adopted, compatible with the advanced and strict data communication protocol of the technical system, and comes with error correction and encryption. Data transmission never loses packets, and can transmit the above pictures and animation files without mosaic phenomenon. It is powerful and supports two working modes: (system default) and, in data transmission mode, the serial port of the user device can be Data (or , B can also be networked with products of the same type as B (convenient for use without Internet conditions), and can realize one-to-one and one-to-many networking plug-and-play functions: When networking with company B or B itself, this Without any software and hardware development, you can build an automatic registration mechanism for large-scale systems, realize multiple service modes, and build a complete ultra-large-scale wireless application system. Remote sleep and wake-up: you can use a designated mobile phone number to dial the number for sleep and wake-up. , convenient for users to put it to sleep when not in use, greatly saving traffic fees. Remote parameter modification: supports SMS parameter modification, and network parameter modification switch function: has two switch inputs and two switch outputs. Can be controlled and read remotely. The alarm status threshold can be set, and whether the alarm will automatically report an alarm signal can be set. Powerful communication backup function: supports automatic switching of the connection between the main server and the backup server. Once there is a problem with the main server, it will automatically connect to the backup server. Powerful server software support. The server software has been used for many years. It is powerful, mature and has dedicated support. The data center supports fixed and dynamic domain name resolution. Industrial grade temperature range: Working temperature: ℃℃ , communication is not affected at ℃.

Local parameters
: The unique identifier, which plays a role in the communication process. Card number: the number of the card used, only for user records and reconnection interval: If the connection to the primary server or backup server fails or is disconnected, the time interval for reconnecting to the backup server or primary server. Local port: the local or port heartbeat period: the interval between heartbeats and the server, in seconds, with a maximum range of packets. Long: the maximum number of bytes in one packet of data sent (optional or bytes). Minimum packet interval: the minimum interval time of data packets (). If the interval between two data received by the serial port is smaller than this value, it will be regarded as one packet, ~ The unit is the no-response reconnection period: how long it takes to not receive a response from the server before it is considered that there is a problem with the network and the network should be reconnected. If set to , this item will not be checked. Range debugging output information: some working status information will be output during work, :does not output debugging information, outputs simple debugging information, :outputs detailed debugging information. When the user connects the device, it is recommended to set it to to avoid output information from interfering with the user's device. Device type: There are,, and three types. This parameter is readable but cannot be set. When the user uses it, the user is prohibited from changing this parameter. Area code: the working area code to which it belongs. This parameter is generally not used, and may only be used in networking. Area code is valid: the work area code it belongs to enables or disables the central control number: the mobile phone number that controls sleep and wake-up and SMS parameter change. If this number is set, the number will be called. It can enter sleep or wake up after giving. Sleep mode saves data charges. If the number is empty, any call from any mobile phone number will cause it to sleep or wake up. Therefore, it is recommended that the user must set a number SMS control number: this number will only work when the work type is selected, and up to three numbers can be set. After setting this number, only the mobile phone with this number can send text messages to it, and no other numbers can send text messages to it. If all three numbers are set to empty, any mobile phone number can send text messages to it. Automatic alarm: When set to enabled, an alarm signal will be automatically sent to the server, otherwise no alarm signal will be reported. Threshold (foot): When automatic alarm is enabled When setting the status, high level is an alarm or low level is an alarm. The interface is the terminal B threshold (pin) from left to right: when the automatic alarm is enabled, set the status of B to be high level as an alarm or low level as an alarm. The maximum number of reconnections for the terminal of the interface from left to right: when it cannot connect to the server for how many consecutive times, it will restart. Parameters and server parameters
The name of the access point. In China, it is username: the login account name. When the user uses the network, he must enter the username and password: Login password Master server: The address of the connected master server Master server port: The port of the connected master server Network protocol: The protocol used by the connected master server, including With two user protocols: regular (), compatible), and transparent), currently all are regular () without special needs. Users are prohibited from changing the backup server: The address of the backup server to be connected. Users can also set this value to the same as the primary server. Alternate server port: The port of the alternate server to which the connection is required. Users can also set this value to be the same as the master server. Serial port parameters
Baud rate: The rate used by the serial port, optional from b Data bits: The data bits of the serial port. Optional,,, four stop bits: The stop bits of the serial port data, three options are available:,,., Generally bit check: The serial port data verification method, with or without verification, even parity, odd Verification, r, etc. Flow control: Whether serial port data transmission has flow control, whether there is flow control, hardware flow control, and software flow control are available. General users have no flow control. < .Application areas Water, electricity and gas remote automatic meter reading display screen information transmission water conservancy and meteorological data collection transmission machine networking power automation, distribution station change monitoring industrial instrumentation automation engineering chain or multinational unit equipment monitoring pipe network
