Embodiment Construction

[0020] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] like figure 1 As shown, the PLC and the power supply of the titanium pump are connected to the PC through a switch. With the PC as the client, the PLC and the titanium pump power supply as the server, the PC client sends a connection request. After the connection is successful, the PLC and the titanium pump power supply will continue to provide data feedback. The PC client collects all the data, and makes the host computer through LabWindows / CVI to visualize the received data. At the same time, the PC client is set with a titanium pump abnormal coefficient threshold. When the titanium pump voltage and current data fed back to the PC client by the titanium pump power supply exceeds the titanium pump abnormal coefficient threshold, th...

Abstract

The invention discloses a thermal measurement pretreatment and storage monitoring system for filaments of cyclotron traveling wave tubes, belonging to the technical field of microwave and millimeter wave electric vacuum devices. The system includes a PC client, a programmable logic controller (PLC), a titanium pump power supply, a program-controlled constant current module, and a multi-channel rail relay; through the interaction between the PC client and the PLC and the titanium pump power supply, the gyrotron traveling wave tube heat The semi-automatic process of the preprocessing of the measurement and the storage monitoring; when there is no power transmitter available, the traveling wave tube can be prepared in advance using the system of the present invention before the thermal measurement, which saves a lot of time and tedious procedures. After baking, the traveling wave tube can be directly loaded on the power transmitter for thermal testing. In addition, after the heat test is over, the filament can be conveniently and quickly baked regularly during storage using the system of the present invention, so as to ensure the functional integrity of the traveling wave tube when it is used again later.

Description

technical field [0001] The invention belongs to the technical field of microwave and millimeter wave electric vacuum devices, and relates to the necessary links of preprocessing and storage display processing of a high-power millimeter wave cyclotron traveling wave tube automatic thermal measurement system. Background technique [0002] The gyrotron, the mainstream of high-power millimeter-wave devices, is an important high-power millimeter-wave source. It has the characteristics of wide frequency bandwidth and high power, and has a high degree of participation in the application fields of national defense, scientific research, and civil communications, so it is highly valued by the country and the people both at home and abroad. [0003] After years of development, the thermal measurement link of the gyrotron traveling wave tube has been relatively mature. The filament of the traveling wave tube is used to heat the cathode of the traveling wave tube to provide a suitable ca...
