Mentality of designing of the present invention is: adopt the control logic circuit take microprocessor as core, can receive by the mode of bus communication corresponding steering order, also can directly link to each other with gauge tap by wire and fetch the variation that obtains on off state, microprocessor is controlled the control signal that the state of the communication instruction that receives or gauge tap is converted into relay to relay, thereby realize the function of traditional insurance relay box, simultaneously microprocessor carries out current detecting by current detection circuit to the main switch control loop of each road relay, and compare with control signal, carry out logic and judge, realize fault diagnosis and warning function.
Therefore the present invention includes:
Micro treatment control system, described micro treatment control system be used for to receive steering order, and the steering order that receives is converted into the control signal of relay, and the break-make at least one relay master switch loop is controlled;
Relay, for the break-make of control external electric equipment, the control end of described relay is connected to micro treatment control system, by the break-make of micro treatment control system pilot relay.
Further: described micro treatment control system has the current detecting control module, and the electric current in relay master switch loop is detected control.
Further: described current detecting control module is that the current detection circuit that is connected on the relay master switch loop is detected.
Further: described microprocessor control system receives the bus steering order in the bus communication mode, according to the actuating of relay of bus communication content-control, and the duty of relay is outwards sent by bus.
Further: described microprocessor control system has the I/0 modulate circuit, can receive high level or the low level signal of operation-control switch, and can control corresponding relay according to the signal that switch provides.
Advantage of the present invention is by changing relay control mode, increase simultaneously the current sense function of the main control loop of relay, thereby in the use that does not change traditional electrical appliance kit, maintenance mode, increase fault diagnosis functions and warning function, and increase total line traffic control function.
