In figure: shell 1, power switch 2, acquisition sensor 3, speech chip 4, voice output 5, power supply 6, battery folder 7, the first digiverters 8, central processing unit 9, the second digiverters 10, hummer 11.
Embodiment
Embodiment 1:
As shown in Figure 1, the utility model is a kind of portable SF
6equipment Leakage Gas and abnormal speech identification warning device.A kind of substation operation equipment generation SF prevented in indoor environment
6leakage Gas and abnormal temperature produce the gas burnt and detect the speech recognition reminding alarm device.The utility model is to be provided with power switch 2 on shell 1, and shell 1 top is provided with acquisition sensor 3, and shell 1 internal upper part is divided into circuit board, and the circuit board bottom is battery folder 7.Described circuit board is provided with speech chip 4, voice output 5, power supply 6, the first digiverters 8, central processing unit 9, the second digiverters 10.Wherein acquisition sensor 3, speech chip 4, power supply 6, the first digiverter 8, the second digiverter 10 all are connected with central processing unit 9, and voice output 5 is connected with speech chip 4 and hummer 11 respectively again.Warning device described in the utility model also can be handheld structure.
As shown in Figure 2, the utility model mainly comprises: five parts such as detectable concentration detection module, pick-up unit module, single chip machine controlling circuit module, speech chip module, local voice alarm module.
Wherein the pick-up unit module comprises that acquisition sensor etc. is containing optical devices; The speech chip module comprises identification, information storage conversion process; The local voice alarm module comprises circuit.
Workflow of the present utility model is as follows:
By power supply 6 by power delivery to single-chip microcomputer center-control processing module; By acquisition sensor by the communication that gathers to the concentration detection module, by the concentration detection module, the gas that receives and concentration and the ANOMALOUS VARIATIONS information of temperature are detected again, afterwards testing result is delivered to single-chip microcomputer center-control processing module, testing result is processed and is transferred to the speech chip module by single-chip microcomputer center-control processing module again, the speech chip module is identified, is transferred to the local voice alarm module after information storage conversion process the testing result received; The local voice alarm module passes through voice loudspeaker or hummer to the result received, and sends voice suggestion or warning.
Pick-up unit module wherein: comprise acquisition sensor 3, containing optical devices, can realize the propagation function to the detection module information processing of concentration and temperature.Described acquisition sensor 3 can be gas sensor or temperature sensor.
Principle of the present utility model is to use the intensity that detects the infrared ray spectral technology by concentration and the ANOMALOUS VARIATIONS of corresponding strong and weak gas and temperature, according to strong and weak amplitude detection, sets and reports to the police by information such as acquisition sensors.
The concentration of detection display gas and temperature and ANOMALOUS VARIATIONS in real time, the information of alarm concentration and ANOMALOUS VARIATIONS can be set on request at the scene.
