Device for monitoring current and voltage of laser direct imaging equipment

Abstract

The invention discloses a device for monitoring current and voltage of laser direct imaging equipment. The device comprises a plurality of transmitters, a signal acquisition module, a switch, an upper computer, a control module, an alarm module and a shutdown protection module, wherein the transmitters are used for converting current and voltage of a plurality of working module power supplies of the laser direct imaging equipment into a plurality of digital signals in a one-to-one correspondence manner; the signal acquisition module is used for acquiring a plurality of digital signals and sending the plurality of signals to the switch; the switch is used for sending a plurality of received digital signals to the upper computer; and the upper computer analyzes the working states of the working modules according to the received digital signals, and notifies the control module to send a control instruction to the alarm module and the shutdown protection module according to an analysis result. According to the invention, the working state of current and voltage of each working module power supply of the laser direct imaging equipment can be monitored in real time, and alarm prompt and power-off protection can be carried out on the working module in an abnormal state.

Description

technical field [0001] The invention relates to the electrical field, in particular to a device for monitoring the current and voltage of laser direct imaging equipment. Background technique [0002] Laser direct imaging equipment includes many important working modules, and the normal operation of these working modules ensures the normal operation of laser direct imaging equipment. These working modules can be, for example, sensors, light sources, laser modules and drivers. In order to ensure the normal operation of the important working modules of the laser direct imaging equipment, it is necessary to supply power to each important working module mentioned above, and to monitor whether the current and voltage of each working module are within the set range at all times. However, in the prior art, because it is impossible to constantly monitor whether the important working modules of the laser direct imaging device are in a normal working state, some accidents occur, so th...
