Embodiment Construction

[0012] In the figure, the remote DC load controller (100) includes a load management center module (30), n independent intelligent switch modules (40) and auxiliary power supply (20). The externally fed DC power supply (1) is connected to the auxiliary power supply (20) and each intelligent switch module (40). n independent intelligent switch modules (40) are connected to n direct current loads (6). The remote DC load controller (100) receives serial data sent by the upper management computer (3) through the external data bus (2), receives discrete control signals (4) and sends discrete control commands, which are processed by the load management center module (30) Afterwards, the n-way switch command line (102) transmits the n-way DC load (6) working mode commands to the n-way intelligent switch module (40). The intelligent switch module (40) monitors the running state of the DC load (6), and reports the running state information of the DC load (6) to the load management cen...

Abstract

The invention relates to a remote direct-current load controller, comprising a load management center module, a plurality of intelligent switch modules and an auxiliary power supply module; the remote direct-current load controller is characterized in that: the load management center module is composed of a data converter, a data transceiver, an interface isolating circuit, a data processor and a control selective circuit; the intelligent switch module is composed of a MOSFET switching tube, a fuse protector, a transient voltage inhibitor, a sampling resistance, a fly-wheel diode, a MOSFET switching tube driving circuit, a current sampling circuit, a voltage sampling circuit, a temperature sensor, a short-circuit protecting circuit, a microprocessor, a control synthesizer, an interface isolating circuit and an isolating power supply. The remote direct-current load controller has the advantages of important mission reliability: when an external data bus loses effect, the controller can use discrete type signal to carry out overriding control; the internal intelligent switch modules have the capacity of directly executing command signals when control software has no effect.

Description

technical field [0001] The invention relates to a remote direct current load controller. Background technique [0002] In the current electromechanical control system and power distribution system, there are generally two ways to control electrical loads: one is to transmit electrical energy to electrical loads through traditional electromechanical circuit breakers, contactors, fuses and thermal relays ; The other is to use solid-state relays to replace traditional electromechanical circuit breakers or contactors, and then add fuses and thermal relays to transmit electrical energy to electrical loads. These two methods are difficult to obtain the operating status of the load, do not have the function of health diagnosis and active real-time monitoring, and it is difficult to carry out precise protection and control for different load characteristics to achieve the purpose of safe and reliable operation. Contents of the invention [0003] The purpose of the present inventi...
