Abstract
The utility model discloses a CAN bus-based electric fire hazard monitoring system in a textile workshop, which comprises a central monitor, one or a plurality of fire hazard monitors, a critical parameter storage and an alarm device. The one or the plurality of fire hazard monitors are connected with the central monitor through a CAN bus. The data port of the central monitor is connected with the data port of the critical parameter storage. The control output end of the central monitor is connected with the control input end of the alarm device. According to the technical scheme of the utility model, the plurality of fire hazard monitors can be detected in real time by means of the CAN bus. In this way, upon the detection of the alarm information, the alarm node position, the alarm type, the alarm value the pre-set value and the like can be displayed. Therefore, the occurrence of electric fire hazards can be effectively prevented.
Description
Technical field
The utility model relates to a kind of fire monitoring system, relates in particular to a kind of spinning and weaving workshop electric fire monitoring system based on CAN bus.
Background technology
Textile industry belongs to highly dense type manufacturing enterprise, electromechanical equipment aging, electric leakage and Misuse electrical equipment all may cause electrical fire, due to electrical fire, to have occurrence frequency high, time of origin and place are random, endanger the features such as large especially, in spinning and weaving workshop, in its processed finished products, be mostly inflammable articles, once there is the condition of a fire, do not control in time consequence hardly imaginable, traditional bus type electric fire alarm is (such as two buses, RS-485 etc.) there is certain defect: data rate is low, distance is short, data loss rate is high, attachable detector quantity is less, cannot give full play to the advantage of bus type electric fire alarm device.
Utility model content
The purpose of this utility model is high with regard to being to provide a kind of data transmission efficiency in order to address the above problem, in real time the spinning and weaving workshop electric fire monitoring system based on CAN bus of monitoring.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises central monitor, one or more fire monitors, critical parameters storer and warning device, one or more described fire monitors are connected by CAN bus with described central monitor, the FPDP of described central monitor is connected with the FPDP of described critical parameters storer, the control output end of described central monitor is connected with the control input end of described warning device, described fire monitor comprises current transformer, isolating switch and temperature sensor, the signal output part of described current transformer is connected with the signal input part of described master controller respectively with the signal output part of described temperature sensor, the control output end of described master controller is connected with the control input end of described isolating switch, the exchanges data port of described master controller is connected with the exchanges data port of described central monitor.
Further, the output terminal of described current transformer is provided with amplification modulate circuit.
Particularly, described warning device is audible alarm unit or photoelectric alarm device.
As preferably, described isolating switch and described current transformer are successively set between power transmission line and user load.
The beneficial effects of the utility model are:
The utility model detects a plurality of fire monitors immediately by CAN bus, once there is warning message, the position of display alarm place node, type of alarm, alarming value and setting value etc., send sound and light alarm signal simultaneously, remind fire fighter to go to scene to ascertain the reason in time, effectively the generation of preventing electric fire.
Accompanying drawing explanation
Fig. 1 is system flow schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the utility model comprises central monitor, one or more fire monitors, critical parameters storer and warning device, one or more described fire monitors are connected by CAN bus with described central monitor, the FPDP of central monitor is connected with the FPDP of critical parameters storer, the control output end of central monitor is connected with the control input end of warning device, fire monitor comprises master controller, current transformer, isolating switch and temperature sensor, the signal output part of current transformer is connected with the signal input part of master controller respectively with the signal output part of temperature sensor, the control output end of master controller is connected with the control input end of isolating switch, the exchanges data port of master controller is connected with the exchanges data port of central monitor.
As shown in Figure 1, the output terminal of current transformer is provided with amplification modulate circuit, and warning device is audible alarm unit or photoelectric alarm device, and isolating switch summation current transformer is successively set between power transmission line and user load.
Principle of work of the present utility model is as follows: transmission line of electricity is received after user load through isolating switch summation current transformer, current transformer detects the leakage current of each group subscriber's line, and detect cable temperature by temperature sensor, then its data are sent to master controller, between master controller and central monitor, pass through CAN bus communication.Each fire monitor must arrange a unique ID, for distinguishing other fire monitor, user is before using, first set as required leakage current alarming value and temperature alarming value and be stored in critical parameters storer, central monitor by instant data that each user load is transmitted relatively after, judge whether to report to the police.Once temperature be detected, surpass critical value, if alerting signal can also be detected, master controller cuts off rapidly circuit to isolating switch, send sound and light alarm simultaneously, and warning message is sent to central monitor, warning device is maintenance sound, visual alarm always, until user's confirmation or fix a breakdown after could recover normal, can also store alarms information, as fire fighter, investigate the foundation of cause of fire.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., all should be included in protection domain of the present utility model.
