The role of the vehicle loop detector in the parking lot system In the parking lot system, to determine the role of the loop detector, we must first know the location of the detector installation. The loop detector is generally installed in the following four positions: 1. At the entrance tick

How to test the rectifier bridge is good or bad? With a digital multimeter diode file or pointer table 100 or 1000 files, measure the two AC input to the output of the rectifier bridge resistance, if it is an open circuit or short circuit that the rectifier bridge has been bad. The normal value shou

The role of rectifier bridge: the rectifier function of bridge rectifier is through the diode's single conduction principle to complete the work, to achieve the conversion of alternating current to direct current. Rectifier bridge is divided into full bridge and half bridge. The full bridge is conne

The principle of parking lot vehicle detector and ground sense coil 1. Working principle The ground induction coil vehicle detector is a vehicle detector based on the principle of electromagnetic induction. It usually embeds a toroidal coil under the road subgrade of the same lane, and passes

Now let Acendant teach you some common minor faults and solutions, hoping to help you.

In the electronics industry, one of the most popular applications of semiconductor diodes is to convert alternating current (AC) signal of any frequency, which is typically 60 or 50 Hz, to a direct current (DC) signal. This DC signal can be used for powering electronic devices, rather than batteries
