Description
Technical field
The utility model relates to a kind of fire hydrant monitoring device, is specially a kind of fire hydrant bump vibration monitoring device.
Background technology
Fire hydrant plays key effect as the infrastructure of urban fire control in fire extinguishing.China's fire hydrant mainly comprises following three types: town road is joined the fire hydrant of building, and the fire hydrant of building is joined by unit, and residential building is joined the fire hydrant of building.Because the installation of fire hydrant disperses very much, emergency case is many, when receiving external impacts; For example clash into by dolly or than big article; Situation such as copper sleeve is knocked when stealing are very serious, cause municipal fire hydrant to be destroyed, if in time do not find; Fire-fighting work in the future brings great hidden danger, has had a strong impact on carrying out smoothly of fire-fighting fire extinguishing rescue.
The utility model content
To the problem that exists in the prior art, the purpose of the utility model is to provide a kind of technical scheme of fire hydrant bump vibration monitoring device.
Described fire hydrant bump vibration monitoring device; It is characterized in that: in the fire hydrant top end cover, vibrating sensor is set; Vibrating sensor links to each other with the MCU controller through low-pass filter circuit, and the MCU controller is delivered to the telecommunication server with detection signal through wired or wireless mode.
Described fire hydrant bump vibration monitoring device is characterized in that described vibrating sensor and fire hydrant top end cover body laterally arrange, and promptly vibrating sensor and ground are 90 degree.
Described fire hydrant bump vibration monitoring device is characterized in that being provided with pcb board in the described fire hydrant top end cover, and pcb board and ground are 90 degree, and vibrating sensor is equipped with on pcb board, in pcb board one side MCU controller and transmitting antenna is set.
Described fire hydrant bump vibration monitoring device is characterized in that described vibrating sensor adopts spring vibration switch SW-18015P.
Described fire hydrant bump vibration monitoring device is characterized in that described MCU controller sends data through GPRS to the telecommunication server.
The utility model detects the omnibearing bump vibrational state of fire hydrant, and sends signal to Surveillance center and in time report to the police, and realizes unified management; Remove the task of daily on-site hydrant supervision and management from; When the condition of a fire takes place, can locate fire hydrant fast, improve the success rate of fire brigade's fire fighting, the reasonability of aid decision city fire hydrant layout; In time fast fire hydrant is safeguarded; Practice thrift a large amount of freshwater resources, the loss of the people's lives and properties of having avoided causing because of fire hydrant is unavailable improves the effective way of public fire protection service level and socialization level; Reduce fire hydrant management, maintenance cost, fire department, water undertaking and social safety are all had great realistic meaning.
Description of drawings
Fig. 1 is the mounting structure sketch map of the utility model;
Fig. 2 is the signal processing flow figure of the utility model;
Among the figure: 1-fire hydrant top end cover, 2-PCB plate, 3-MCU controller, 4-transmitting antenna, 5-vibrating sensor, 6-low-pass filter circuit.
The specific embodiment
Below in conjunction with Figure of description the utility model is further specified:
Fire hydrant bump vibration monitoring device is provided with vibrating sensor 5 in fire hydrant top end cover 1, vibrating sensor 5 links to each other with MCU controller 3 through low-pass filter circuit 6, and MCU controller 3 is delivered to the telecommunication server with detection signal through wired or wireless mode.
The vibrating sensor 5 of the utility model adopts spring vibration switch SW-18015P, and its structure is made up of conductive connecting pin, power spring, plastic cement body etc., and vibrating sensor 5 laterally arranges with fire hydrant top end cover 1 body, and promptly vibrating sensor and ground are 90 degree.Be provided with pcb board 2 in the fire hydrant top end cover 1; Pcb board 2 is 90 degree with ground; Vibrating sensor 5 is equipped with on pcb board 2, in pcb board 2 one sides MCU controller 3 and transmitting antenna 4 is set, and MCU controller 3 sends data through GPRS to the telecommunication server in the utility model.
Operation principle: when outer mechanical force conducts to vibrating sensor through the fire hydrant housing; Masterpiece is used for power spring; When power spring is displaced to critical point, produce snap action, make the movable contact of power spring body and fixedly conductive connecting pin collision generation connection fast; After the active force on the vibrating sensor was removed, simultaneously power spring produced counteragent power, reach the action critical point of reed when the vibrating sensor reverse stroke after, breaking off fast promptly appears in instantaneous completion counteragent.The contact spacing of vibroswitch is little, and actuating length is short, and it is little to press power; Break-make is rapid, and the responsiveness of its movable contact and vibrating sensor responsiveness are irrelevant, after vibration signal produces; Sensor is through filter circuit, high-frequency interferencing signal is shielded a part after, be connected to the external interrupt mouth of MCU controller; Avoid appearing at MCU and frequent false triggering phenomenon occurs, improve the reliability of single-chip microcomputer work because of interference.
During lower stress, vibrating sensor is not shaken or small shake on having big external impacts or vertical impact, is can triggering signal; When receiving big external impacts or by the side when stressed, as pound, hit, sled etc., the particularly copper sleeve of fire hydrant receive the thief when beaing; Can produce strong vibration signal, pass to MCU, the timing that then can start MCU detects vibration signal number of times program; Whether in the time (as: giving tacit consent at present 30 seconds) that limits, reach the vibration number (as: giving tacit consent at present 80 times) that sets by detecting vibration signal; Can prevent that like this erroneous judgement that some non-artificial pilferages etc. cause is disconnected,, then produce vibration fault status signal sign if reached the number of times of setting at official hour; Set the fault steady state flag; Through steady state flag, write the current data formation, send data through GPRS to the telecommunication server then; If reach setting-up time, and do not reach vibration number, then the vibration number accumulator register is automatically clear 0, gets into sleep state then; For saving battery electric power consumption, the time can not trigger less than 5 minutes once more after setting the steady state flag position.After host computer receives vibration signal; The vibration real-time animation state that can on man-machine interface, show the reference numeral fire hydrant; And record historical data base and Mishap Database, and send the malfunction that note is informed administrative staff's fire hydrant simultaneously, repairing is arranged in prompting as early as possible.
The utility model detects the omnibearing bump vibrational state of fire hydrant, and sends signal to Surveillance center and in time report to the police, and realizes unified management; Remove the task of daily on-site hydrant supervision and management from; When the condition of a fire takes place, can locate fire hydrant fast, improve the success rate of fire brigade's fire fighting, the reasonability of aid decision city fire hydrant layout; In time fast fire hydrant is safeguarded; Practice thrift a large amount of freshwater resources, the loss of the people's lives and properties of having avoided causing because of fire hydrant is unavailable improves the effective way of public fire protection service level and socialization level; Reduce fire hydrant management, maintenance cost, fire department, water undertaking and social safety are all had great realistic meaning.
