Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Embodiment
With reference to shown in Fig. 1, the remote switch apparatus control system that a kind of bringing onto load detects, comprise for the A.C. contactor 3 of control load loop break-make, switch controlling device 1 and communicator 2, wherein, load circuit comprises the load 4 be connected between zero line and phase line, and A.C. contactor 3 is connected between zero line and phase line.
Switch controlling device 1 comprises first processor 11, Hall current sensor 13, amplifier 14, relay 12, CAN controller 16 and control panel 15, first processor 11 is connected with amplifier 14, control panel 15, relay 12 and CAN controller 16 respectively, Hall current sensor 13 is arranged on load circuit, its output terminal is connected with amplifier 14, for the electric current in sensing lead loop, and first processor 11 is fed back to after amplifier 14 amplifies, first processor 11 can judge the duty of load 4 according to the electric current of feedback; Relay 12 is controlled by first processor 11 for controlling A.C. contactor 3 break-make, and first processor 11 is MCU processor.
A.C. contactor 3 is provided with for the host node of control load loop break-make and the auxiliary node 31 that links with host node, and auxiliary node 31 is connected the action situation being used for feeding back host node to it with first processor 11.
Communicator 2 comprises the second processor 22, the CAN controller 21 be connected with the second processor 22 respectively and LAN controller 23, CAN controller 16 is connected with CAN controller 21, LAN controller 23 is connected with host computer, first processor 11 realizes telecommunication by communicator 2 and long-range host computer, can receive host computer instruction and control the break-make of A.C. contactor 3 and the duty to host computer feedback load 4 by relay 12.Communicator 2 can access multiple Light Control Unit (127) by CAN mode, and uses LAN controller 23 and host computer carry out networking and realize Long-distance Control flexibly; Second processor is arm processor.
From structure, the logical and Traditional control of control section of the present invention is consistent, therefore, does not need to carry out too much extra design, particularly for improvement project, without the need to changing the position of load circuit and contactor; Only need replacement switch controlling device 1 can realize the functions such as Long-distance Control, on the spot control, the equipment state supervision of equipment.
The course of work:
By switching long-range, the mode selector switch on the spot of control panel 15, export to first processor 11 1 amount of logic to arrange the mode of operation of whole switch controlling device 1.
Remote mode: after host computer forwards switch order to the instruction of communicator 2 transmit button, communicator 2 to corresponding switch controlling device 1 by LAN, switch controlling device 1 receives switching control instruction, control the action of its relay 12 to reach the object of control load 4; Simultaneous Switching control device 1 can send current on off state and the result of switch order by communicator 2 to host computer, and the fault of equipment.
With regard to ground mode: when being on the spot under control model, Long-distance Control is invalid; Carry out operation can return corresponding error message if at this time long-range; First processor 11 carrys out the action of pilot relay 12 by the state that button leaves, thus realizes the open and close to load 4.
Load operating condition monitoring and protection: very extensively, we select the Hall current sensor 13 of 0-80A can meet the power requirement of load 4 under application scenarios here for the sensitivity of Hall current sensor 13 and measurement range.When concrete enforcement, by the bearing power scope such as 10A-12A of host computer deploy switch control device 1.After load circuit is unlocked, first processor 11 just can be judged the duty of load 4 by the sampled value calculating Hall current sensor 13.When electric current is lower than 10A, can distally send the too low alarm of load 4 by communicator 2; When load 4 electric current distally can send the alarm of overload higher than 12A, the load circuit of switching off load 4 is protected simultaneously; Further, can be judged the state of load circuit, if the abnormal state of auxiliary node 31, distally can send alarm information by the auxiliary node 31 of A.C. contactor 3, this time may be that A.C. contactor 3 damages or load circuit dead electricity.
The above, be only preferred embodiment of the present invention, therefore can not limit scope of the invention process with this, and the equivalence namely done according to the present patent application the scope of the claims and description changes and modifies, and all should still remain within the scope of the patent.
