Abstract

The invention discloses a device status monitoring information terminal. An aviation plug is connected with a three-phase external connector through a three-phase line arranged inside a terminal. A current sensor and a voltage sensor are used for detecting the current and voltage of the three-phase line. A current signal of the three-phase line is connected to three ADs of a controller after amplitude-limited by a conditioning circuit A, and a voltage signal of the three-phase line is connected to the other three ADs of the controller after amplitude-limited by a conditioning circuit B. One phase of the three-phase line is connected with a single-phase external connector. According to the invention, power equipment is connected to the three-phase external connector or the single-phase external connector according to the type of power needed, which is equivalent to the situation in which the terminal is externally and electrically connected in series to the power supply line of the power equipment. Thus, the current and voltage of a power supply line can be measured without the need for an additional switching line. The terminal can also monitor environmental parameters, support access of other network interface expansion peripherals, and provide various types of interfaces. The flexibility of the terminal is improved.

Description

technical field [0001] The invention belongs to the field of field equipment power supply and distribution, and in particular relates to an equipment status monitoring information terminal. Background technique [0002] With the development of science and technology, the number of on-site electrical equipment is increasing day by day. Some large-scale electrical equipment that is lagging behind in upgrades or equipment that does not consider parameter monitoring in design is becoming increasingly important but relatively weak in power distribution management, power consumption, and operating status monitoring. It is too costly to upgrade the equipment that is in service and still meets the needs of the site to realize functions such as power distribution management and operation status monitoring. Therefore, on the premise of not changing the technical status of the existing equipment, adding a monitoring terminal to the equipment can realize the collection of relevant infor...
