The purpose of the utility model realizes through following technical scheme:
A kind of intelligent surge protector with the RS485 interface; Comprise surge release module, lightning induction module and lightning stroke counter; Surge is released and the lightning induction module is set on the ground wire of module; The signal output part of lightning induction module connects lightning stroke counter, and the RS485 communication module is set in the said lightning stroke counter.
Preferably; Said lightning stroke counter further comprises lightning strike signals processing module, microcontroller processor, display module and RS485 communication module; The signal output part of lightning induction module connects the lightning strike signals processing module; The output of lightning strike signals processing module connects the microcontroller processor, and the microcontroller processor connects display module and RS485 communication module.
Preferably, the RS485 communication interface of said RS485 communication module for being connected with peripheral hosts through transmission cable.
Preferably, said lightning stroke counter also comprises the power module to the lightning stroke counter power supply.
Preferably, the said surge module of releasing is made up of surge protection device.
Preferably, said lightning induction module is the thunderbolt transducer.
Compared with prior art, the utlity model has following beneficial effect:
The intelligent surge protector of the utility model has realized that through setting up the RS485 communication interface surge protector and peripheral hosts carry out real-time both-way communication and transfer of data; Can be with the working condition of surge protector; As data in real time such as the counting that is struck by lightning, working temperature, remote signalling inefficacy be transferred to main frame, and realize functions such as lightning protection, monitoring, record, warning.The utility model has been realized the two in one technique of surge protector and RS485 interface module on hardware technology, on software engineering, realized the real-time communication technology of surge protector and host computer.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
Be illustrated in figure 1 as a preferred embodiment of the utility model, a kind of intelligent surge protector with the RS485 interface comprises surge release module 1, lightning induction module 2 and lightning stroke counter 3, and is preferred, and release module 1 of surge is made up of surge protection device; The 2 monitoring thunderbolts of lightning induction module take place, and transducer preferably is struck by lightning.Surge is released and thunderbolt transducer 2 is set on the ground wire of module 1, and the signal output part of thunderbolt transducer 2 connects lightning stroke counter 3.
Further; This lightning stroke counter 3 comprises lightning strike signals processing module 31, microcontroller processor 32, display module 33 and RS485 communication module 34; The signal output part of thunderbolt transducer 2 connects lightning strike signals processing module 31; The output of lightning strike signals processing module 31 connects microcontroller processor 32, and microcontroller processor 32 connects display module 33 and RS485 communication module 34 respectively.This lightning stroke counter 3 also comprises the power module 35 to the lightning stroke counter power supply.
Wherein, the RS485 communication interface of RS485 communication module 34 for being connected with peripheral hosts through transmission cable; To the be struck by lightning conversion of signals of transducer 2 input of lightning strike signals processing module 31 becomes desired signal; Microcontroller processor 32 record thunderbolt information, display module 33 shows the information of microcontroller processor 32.
The course of work is following: after the RS485 communication interface in the surge protector connects through the main frame in transmission cable and the Control Room; After the surge protector energising; Inner microprocessor can be controlled the work of RS485 interface module, the host computer that sends to Control Room that the various operational datas of surge protector in the microcontroller processor are real-time.Also receive simultaneously the various instructions that the Control Room main frame sends, the operation that intelligent surge protector is correlated with according to command content again.Surge protector in use can carry out real-time both-way communication with the host computer in the Control Room, thereby realizes real-time transfer of data.
The RS485 interface is a kind of telecommunications industry standard by Electronic Industries Association (EIA) works out and Telecommunications Industries Association revises.The maximum communication distance of RS-485 is about 1219M, and peak transfer rate is 10Mb/S, a kind of communication standard that transmission rate and transmission range are inversely proportional to.In surge protector, increase the RS485 communication interface, be connected with the host computer of Control Room through cable again, can realize real-time communication; The working condition of surge protector; As data such as the counting that is struck by lightning, working temperature, remote signalling inefficacy, the real-time main frame that is transferred to is also accepted various instructions that main frame issues etc. simultaneously; Thereby realized the two-in-one effect of surge protector and the real-time communication of Control Room host computer, thereby realized the function of lightning protection, monitoring, record, warning.
The utility model can solve the shortcoming that existing intelligent surge protector can not carry out real-time communication well; Just can realize that under the situation that does not increase communication cable maximum distance is 1200 meters communication; If the distance of Control Room and surge protector exceeds this communication distance, just can increase communication distance as long as increase by one 485 repeater more so between the two.The RS485 bus at most can plug-in 128 peripheral hardwares in theory; Promptly a host computer can carry out real-time communication with 128 surge protectors with RS485 interface at most, and this has just well solved the real-time communication problem of a host computer in a plurality of intelligent surge protector that is distributed in the same area and the Control Room again.
The intelligent surge protector of the utility model has realized that through setting up the RS485 communication interface surge protector and peripheral hosts carry out real-time both-way communication and transfer of data; Can be with the working condition of surge protector; As data in real time such as the counting that is struck by lightning, working temperature, remote signalling inefficacy be transferred to main frame, and realize functions such as lightning protection, monitoring, record, warning.The utility model has been realized the two in one technique of surge protector and RS485 interface module on hardware technology, on software engineering, realized the real-time communication technology of surge protector and host computer.
More than the disclosed several specific embodiments that are merely the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection range.
