Abstract

The invention relates to a power-up sequence control device and method, a phased-array antenna and a radar. The device comprises a control circuit, a first relay array and a second relay array; the control circuit is connected with all first relays in the first relay array, the first relays in the first relay array are connected with second relays in the second relay array in a one-to-one correspondence mode, and the second relays are connected with electric equipment; the first relay is connected with a first external voltage source, and the second relay is connected with a second external voltage source; and the control circuit controls the gating state of the first relay array according to the received sequence control word, further controls the gating state of the second relay array, and further controls the power-on state and the power-off state of the corresponding electric equipment. The power-up sequence control device can be designed into a single board form, and is simple in structure and low in cost; and the control logic is simple and easy to realize.

Description

technical field [0001] The invention relates to the technical field of control devices, in particular to a power-on sequence control device, method, phased array antenna and radar. Background technique [0002] At present, phased array antennas are widely used. With the diversification of phased array antenna functions, the number of high-power devices in the system is gradually increasing, and the system complexity is getting higher and higher. For general phased array antennas, since many subsystems need to be controlled and the functions to be completed are complex, there is a strict sequence requirement for the power-on and power-off of the high-power subsystems. Currently, the control is realized in the form of control combination, which consists of multiple A circuit board plug-in together completes the control function. [0003] Although this form can meet the power-up requirements of most phased array antennas, when the phased array antenna has restrictions on weigh...
