Embodiment Construction

[0013] In the drawings, like parts are denoted by like reference numerals in different views, and the various elements depicted are not necessarily drawn to scale.

[0014] Refer to attached figure 1 , the figure depicts an embodiment of a 0-150V large-amplitude long-distance control synchronization pulse generator, which is used to realize the synchronization triggering of remote equipment under the condition of strong electromagnetic interference. figure 1 Among them, pulse control terminals 1 and 2 are pulse trigger sources, which are external level trigger and manual trigger respectively. The external level trigger is input through the BNC connector, and the manual trigger is controlled by the self-resetting button. After the pulse trigger signal is generated, it is output to the state lock circuit 5 through the OR gate circuit 4. 3 is the reset control of the synchronous pulse generator, through which the generator can be controlled to restore it from the locked state to...

Abstract

A 0-150 V wide-range remote control synchronous pulse generator consists of a pulse control end, a pulse generating end and a connecting optical fiber and mainly comprises an outer trigger circuit (1), a manual trigger circuit (2), a reset circuit (3), an or-gate circuit (4), a state locking circuit (5), a mode switching module (6), an electro-optical conversion module (7), a single mode fiber (8), a photovoltaic conversion module (9), a 0-150 V adjustable power supply circuit (10) and a pulse generating output circuit (11). The problem that a synchronous control pulse signal cannot effectively trigger level compatibility between a far-end device and different devices under the electromagnetic interference is solved, and the 0-150 V wide-range remote control synchronous pulse generator can be used for triggering of long-distance devices in a strong electromagnetic environment. The scheme involved by the 0-150 V wide-range remote control synchronous pulse generator is achieved mainly by adopting a logic IC, a photovoltaic conversion device, a high-speed MOSFET field effect switch tube and a transmission optical fiber, and when optical fiber transmission time is not calculated, the overall delay of the synchronous pulse generator is smaller than 290 ns from trigger signal input to synchronous pulse signal output, output pulse rising time is about 21 ns, and maximum delay of four pulse outputs is smaller than 500 ps.

Description

technical field [0001] The invention relates to a 0-150V large-amplitude long-distance control synchronous pulse generator. The synchronous pulse generator can adjust the output pulse amplitude, output mode, and pulse width, and uses single-mode optical fiber for control signal transmission to avoid the influence of electromagnetic interference. It can be used to trigger long-distance equipment in a strong electromagnetic environment to ensure multiple Synchronization of actions between devices. Background technique [0002] Modern electronic systems usually contain multiple devices, and each device is required to act in the same way. In order to achieve precise synchronization, a synchronization signal is required for triggering. In some special environments, there is strong electromagnetic interference, and the sync pulse generator is required to be separated from other devices by a certain distance. Usually, the synchronization pulse signal has limited amplitude and ene...
