The boiler shutdown wireless alarm
Technical field
The utility model relates to a kind of boiler shutdown wireless alarm.
Background technology
Boiler is an indispensable part during modernization industry is produced, because high temperature, high pressure, strong noise during boiler operatiopn, make that staff's working environment is very abominable, the staff can not keep in the boiler room in 24 hours, in case the unexpected blowing out of boiler and in time not found in the short time might cause serious accident and bring serious economy loss to production.The skid-mounted type boiler that the oil field is used is all the more so, in case in the unexpected blowing out of boiler in winter and the personnel of patrolling and examining can not in time find and safeguard, not only may cause security incident, also can cause serious injury boiler itself because of arctic weather.Therefore to the monitoring of boiler operatiopn state, it is very important especially to report to the police timely during boiler shutdown.
In field produces, being installed in outdoor skid-mounted type boiler mainly relies on patrolling and examining of staff to check the running status of boiler, also some passes to Surveillance center with the wired alarming mode with the boiler operatiopn state, does not also have the wireless alarm that designs for boiler shutdown specially at present.The wired alarming mode has determined that its construction is inconvenient, the cost height, and safeguard inconvenient.Along with the roller exploitation in oil field, being installed in outdoor unattended skid-mounted type boiler will get more and more, and is very unpractical and the boiler shutdown wired alarming constantly is installed.
The utility model content
The purpose of this utility model is to provide a kind of boiler shutdown wireless alarm, and it is simple in structure, can find in time that radio alarming is carried out in the improper blowing out of boiler, in time notifies the monitor staff, and is easy to use.
The purpose of this utility model is achieved in that a kind of boiler shutdown wireless alarm, comprise the PLC controller, the signal input part of PLC controller is connecting the boiler state detection circuit, the signal output part of PLC controller is connecting SMS module, and SMS module is connecting mobile phone and Long-distance Control host computer by wireless communication networks.
During the utility model work, the boiler state detection circuit is installed on the boiler, carry out uninterrupted monitoring in 24 hours by the PLC controller, when the blowing out state appears in boiler, the mobile phone that the PLC controller can be dialed the monitor staff at once and held by SMS module, if nobody replys mobile phone, then also can send the warning end letter of boiler shutdown at once, also can be simultaneously the blowing out state of boiler be sent on the Long-distance Control host computer by wireless communication networks.Thereby accomplish that the blowing out state of in time finding boiler carries out radio alarming, in time fix a breakdown, guarantee that production safety carries out in order.Roller exploitation along with the oil field, unattended skid-mounted type boiler will get more and more, the workload of patrolling and examining the staff of boiler attendance will be very big, can not carry out 24 hours real-time trackings to whole boilers of widely dispersed safeguards, and wired boiler shutdown alarm is because the roller exploitation in the having a very wide distribution of boiler, oil field, construct very difficult and cost is very expensive, therefore use the utility model radio alarming device that the boiler operatiopn state is monitored, not only cost performance height, and application prospect will be very wide.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a syndeton schematic diagram of the present utility model.
The specific embodiment
A kind of boiler shutdown wireless alarm as shown in drawings, comprises the PLC controller, and the signal input part of PLC controller is connecting the boiler state detection circuit.Said boiler state detection circuit can also can be the temperature signal testing circuit that is made of the temperature signal sensor for the electrical signal detection circuit that is made of electric signal sensor, operating voltage, electric current or boiler temperature to boiler detect, thereby in time find the blowing out state of boiler.The said boiler state detection circuit video monitoring circuit with camera of can also serving as reasons constitutes, by the field condition of camera can the real time record boiler shutdown time.The signal output part of PLC controller is connecting SMS module, and SMS module is connecting mobile phone and Long-distance Control host computer by wireless communication networks.Said wireless communication networks is the wireless communication networks based on GSM, CDMA or 3G.
Boiler shutdown wireless remote alarming device adopts the PLC controller by the boiler state detection circuit boiler state to be detected, after detecting the boiler shutdown signal, PLC moves alert program automatically, uses the GSM SMS module to carry out telephone call, SMS alarm and ipc monitor interface and reports to the police. The characteristic of property of the utility model alarm:
(1), the boiler shutdown mode that report to the police to adopt PLC controller automatic poking phone and send short messages and combine.
(2), boiler shutdown is reported to the police and can be adopted China Mobile GSM network to realize the automated wireless remote alarms.
(3), the alarm control program design becomes: successively dial 3 predefined phone numbers behind the boiler shutdown and report to the police, if 3 equal access failures of mobile phone, then the boiler state is issued predefined 3 phone numbers in the mode of Chinese short message, the notice boiler attendance personnel safeguard boiler.
(4), alarm can be automatically sends to the warning message of boiler on the control interface of remote control center computer with the GSM way of short messages, remind administrative staff that boiler is safeguarded.
