In the utility model, as the parameters are transmitted among the monitors and the detectors in the digital communication manner, the stability and reliability of data transmission are increased, and product performance is greatly improved; the parameters can be set in batches by a monitoring center through a communication bus in a concentrated manner, without being edited at each monitoring point by a user, and are convenient and flexible to modify, so that time and labor are saved; and when the remote network monitoring system is adopted, remote monitoring and remote maintenance are realized, the number of monitoring personnel can be reduced, and the maintenance difficulty of equipment can also be reduced.
Description
Technical field
The utility model relates to detector for electric fire protection, relates in particular to the supervisory system with long-distance on-line function that is used for detector for electric fire protection.
Background technology
Existing detector for electric fire protection product is made up of detector and watch-dog.Communication mechanism between detector and the corresponding watch-dog is: detector (being residual current transformer) is directly exported simulating signal and is given watch-dog.Because detector is positioned on the power distribution cabinet outlet return cable, and watch-dog is positioned on the cabinet face, several meters distance is arranged, therefore the residual current transformer output current is minimum, several mA at zero point zero only have an appointment, often decay is very serious through several meters circuit transmission, is also disturbed easily, so image data is unreliable also unstable.
In addition, existing detector for electric fire protection system generally is equipped with watch-dog, the warning message that is used for the watch-dog of each detector for electric fire protection terminal of centralized displaying, send alarm sound, but watch-dog does not possess the operated from a distance function to all watch-dogs, therefore when the alarm parameters of watch-dog will be set, need to operate the difficulty that has improved the equipment operation monitoring and safeguarded to the scene.
The utility model content
At the above-mentioned deficiency of existing detector for electric fire protection communication control system, the applicant improves through research, provides a kind of data transmission reliable and stable, and monitor parameters is revised convenient, flexible detector for electric fire protection long-distance on-line monitoring system.
The technical solution of the utility model is as follows:
A kind of detector for electric fire protection long-distance on-line monitoring system comprises:
One or more detectors are used to survey residual current and temperature parameter, and described parameter is uploaded to watch-dog with digital transmission mode;
One or more watch-dogs are used to finish the collection of phase voltage and phase current parameter, residual current and the temperature parameter that the described detector of reception transmits, and carry out the final processing and the alarm decision of parameters, the output of threading off;
Watch-dog for being arranged at the Centralized Monitoring main frame of Surveillance center, is used to monitor the duty of all watch-dogs;
Adopt the digital communication mode to carry out the transmission of residual current and temperature parameter between described detector and the watch-dog;
Described watch-dog is connected with watch-dog by 485 fieldbus, and described watch-dog carries out the remote batch setting to the alarm parameters of all watch-dogs.
Its further technical scheme is: adopt 485 interfaces to carry out the transmission of residual current and temperature parameter between described detector and the watch-dog.
Useful technique effect of the present utility model is:
(1) adopts the digital communication mode to carry out the parameter transmission between the utility model watch-dog and the detector, strengthened stability of data transmission, reliability, enhance product performance greatly.
(2) the utility model product can be on-the-spot by menu set alarm parameters, also can by communication bus by the monitoring host computer of Surveillance center concentrate, batch setting, need not the user and be in the action each control point is carried out the parameter editor.It is convenient, flexible, time saving and energy saving to revise.Realize remote monitoring, remote maintenance, also can reduce the monitor staff quantity, reduce the plant maintenance difficulty.
Description of drawings
Fig. 1 is a system chart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described by embodiment.
Fig. 1 is a system chart of the present utility model.As shown in Figure 1, the utility model comprises a watch-dog and many detectors, many watch-dogs.
Described watch-dog is the Centralized Monitoring main frame that is arranged at Surveillance center, is used to monitor the duty of all watch-dogs.Watch-dog is connected with watch-dog on each bar cable by a plurality of 485 minutes loops.
Described detector and watch-dog are cooperatings, and both can have two kinds of connected modes: a kind of connected mode is that each watch-dog connects a detector by connection; Another kind of connected mode is that each watch-dog is by many connection linking number platform detectors.
Detector is connected on between electric loading and the isolating switch, is used to survey residual current and temperature parameter, and described parameter is uploaded to watch-dog with digital transmission mode (as RS485).Watch-dog is connected with detector by the RS485 connection, and connection isolating switch, be used to finish the collection of phase voltage and phase current parameter, residual current and the temperature parameter that the described detector of reception transmits, and carry out the final processing and the alarm decision of parameters, the output of threading off.Watch-dog is connected with watch-dog by 485 fieldbus, and described watch-dog carries out the remote batch setting to the alarm parameters of all watch-dogs.
Principle of work:
See Fig. 1, each detector obtains the residual current Is of cable and the value of temperature T separately respectively by built-in residual current collecting unit and temperature collecting cell, these two parameters is imported connected watch-dog by 485 communication interfaces carry out overall treatment.
Watch-dog obtains the value of the phase current I and the phase voltage U in monitored loop respectively by built-in current acquisition circuit and voltage collection circuit.In watch-dog, phase current I, phase voltage U, residual current Is, this quadrinomial parameter of temperature T that collects carried out AD conversion and data filtering, each parameter is carried out comprehensive computing, the fire alarm possibility occurrence is differentiated, after computing, show when entering the fire abnormal alarm, send sound and light alarm, effectively remind the monitor staff; In needs, isolating switch is sent the instruction of threading off and make circuit breaker tripping, to avoid the generation of electrical fire.Meanwhile, watch-dog each parameter that will collect and fire alarm are differentiated result and watch-dog numbering by the watch-dog of 485 bus transfer to Master Control Center.
Watch-dog is connected with all watch-dogs by 485 fieldbus, form warning net, so watch-dog can monitor the duty of all watch-dogs, when certain watch-dog is reported to the police, watch-dog can send alarm sound simultaneously, the operator on duty of notice duty room.Watch-dog in addition can also remote centralized, the alarm parameters of all watch-dogs of batch setting, need not the user and is in the action each control point is carried out the parameter editor.Avoid loaded down with trivial details execute-in-place, it is convenient, flexible, time saving and energy saving to revise.
The selected RS485 communication module of the selected RS485 communication module of watch-dog and watch-dog is corresponding, makes between them that communication is reliable and efficiently, has certain confidentiality simultaneously.The control program of watch-dog is suitable, efficiently, can monitor many different watch-dogs, and watch-dog display frame is readable, hommization, exercisable.
Above-described only is preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that those skilled in the art under the prerequisite that does not break away from spirit of the present utility model and design, can make other improvement and variation.
