Disclosed is a water-cooled radio frequency tumor extinguishing treatment system, which employs radio frequency heating means to place the target tissue in human body into between the melting electrode and leading electrode, a series resonant circuit is utilized in the radio frequency energy amplification, the rear portion of the melting electrode needle of the cold circulating pinshaped electrode is plated with an insulation coating layer, a bare tip is formed on the front end, thus the radio frequency energy capacity can radiate from around to the leading electrode, as a result, a melting zone is formed. The recirculated cooling water flows from the inlet pipe to the melting electrode needle, and returns to the recirculated cooling water subsystem from the exhaust pipe after heat interchange.

The invention relates to a low-voltage electrical appliance communication protocol adapter which comprises double single chips, double Modbus-RTU protocol converting circuits, a Profibus-DP, a DeviceNet protocol converting circuit, an off chip data memory, an LCD (liquid crystal display) screen and a keyboard, wherein on chip universal asynchronous receiver-transmitters of the double single chips are respectively connected with the Modbus-RTU and an RS485 level converting transceiver circuit; an on chip control local area network is respectively connected with double DeviceNet converting transceiver circuits to finish acquiring low-voltage electrical appliance data and responding to bus commands and events; meanwhile, I2C communication modules of the single chips are connected with the off chip data memory based on I2C to finish storing the data and extracting processed low-voltage electrical appliance parameters. Due to the adoption of double processor operations and a caching technology, technical schemes such as response time, and the like when other adapters are operated are reduced so as to ensure that the low-voltage electrical appliance communication protocol adapter becomes a centralized controller, a small network server and an adapter. The adapter can hang at most three buses, thereby increasing the adaptability of low-voltage electrical appliances during networking and facilitating users mounting.

The invention discloses a message transmitting method based on an analog communication chip technology, solving the technical problem for uniformly processing the message with different types by providing a complete set of process logic and transmitting logic. The technical scheme comprises the steps of: setting a special process unit for uniformly transmitting the message on an object plate; memorizing message types which are allowed to be received by a communication chip and communication protocols correlative to the message of the type into a special memory unit which is matched with the special process unit by a CPU; processing the transmitting message by calling the transmitting process logic and allocation which are as the same as the communication chip with a match process software;after processing, returning the message from the special process unit to the communication chip to be processed by means of terminal output; and transmitting the communication chip. The method has the advantages of clear and simple software logic, low procedure complexity, fast software developing speed, and good economic benefit.

The invention relates to a universal protocol conversion platform for the Internet of Things. The universal protocol conversion platform comprises a protocol configuration module, a protocol data processing module and a protocol packaging module; the protocol configuration module is used for realizing self-defined configuration, automatic loading, configuration analysis and protocol coding and decoding generation of an Internet of Things equipment protocol; the protocol data processing module is used for intercepting uploaded protocol data, calling a generated specific protocol decoder through a protocol decoding adapter, and returning the data to an upper management interface; and the protocol encapsulation module is used for realizing that the management interface calls a protocol data operation interface to transmit upper-layer equipment data during data issuing, encapsulating a specific data protocol through a protocol data encapsulator, generating a communication protocol of corresponding equipment and sending the communication protocol to the equipment. According to the invention, a user can arbitrarily configure the equipment communication protocol, and the configuration analyzer can be automatically called according to the user configuration to dynamically generate the protocol decoder, so that the connection, management and communication of the Internet of Things equipment are greatly facilitated, and the economic cost is reduced.
