Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Through embodiment, the technical scheme of the utility model is done further detailed description below.
As shown in Figure 1; A kind of explosion-proof type industrial gasses detector, it includes explosion-resistant enclosure and is arranged on microcontroller circuit, gas sensor, signal filtering amplifying circuit, wireless communication module, sound light alarming circuit, display circuit, power circuit, solar cell, charging and the handover management circuit in the said explosion-resistant enclosure and can discharges and recharges battery;
The said battery that discharges and recharges adopts chargeable lithium cell; Said charging and handover management circuit have the function that detects the solar cell for supplying power ability; When detecting solar cell and can't independently supply power for system; Can automatically switch to the chargeable lithium cell power supply; The chargeable lithium cell capacity is used up and not work of solar cell when detecting, and will force system to get into low power consumpting state, avoids the damage of chargeable lithium cell;
Wherein, said gas sensor connects said signal filtering amplifying circuit, and said signal filtering amplifying circuit connects said microcontroller circuit, and said microcontroller circuit connects said wireless communication module, said sound light alarming circuit, said display circuit respectively; Said solar cell is connected said charging and handover management circuit respectively with the said battery that discharges and recharges; Said charging and handover management circuit connect said power circuit, and said power circuit connects said microcontroller circuit, said signal filtering amplifying circuit, said wireless communication module and said sound light alarming circuit respectively so that working power to be provided.
It in the said explosion-resistant enclosure dual chamber structure; Inner solar cell, charging and handover management circuit, chargeable lithium cell and the wireless communication module installed of upper chamber; The upper chamber certain angle that recedes; Can make solar cell fully receive illumination, windowpane adopts the high transmission rate material, improves light penetration; Lower cavity is installed the main body of circuit part, like microcontroller circuit, gas sensor, signal filtering amplifying circuit, sound light alarming circuit, display circuit and power circuit.
The utility model is the design of whole flame proof, and sunray is radiated at through top high printing opacity flame proof windowpane on 10 square centimeters the high efficiency solar cell plate, and the supply of electrical energy of 5VDC voltage, 1W left and right sides power is provided for complete machine.
The electric energy that the photovoltaic device of solar cell produces through overcharge and the handover management circuit after be divided into two-way; One the tunnel is the circuit system power supply; Another Lu Weike discharges and recharges battery charge, and charging and handover management circuit detect the power supply capacity and the battery electric quantity of solar cell in real time.When the solar cell for supplying power scarce capacity with simultaneously for discharging and recharging battery and circuit system when supplying power simultaneously, will cut off charge circuit automatically.If the power supply capacity of solar cell continue to reduce, can't the back-up system circuit working, charging and handover management circuit switch to solar cell for supplying power and can discharge and recharge powered battery.If charging and handover management electric circuit inspection will make system get into low power consumpting state to discharging and recharging cell voltage when not enough, avoid to discharge and recharge the battery damage.
The power supply that solar cell maybe can discharge and recharge battery to be provided carries out voltage regulation filtering treatment and supplied microcontroller circuit, signal filtering amplifying circuit, sound light alarming circuit, wireless communication module use through power circuit.Gas sensor signal is delivered to microcontroller circuit through the signal filtering amplifying circuit, obtains object gas concentration through calculating, and microcontroller circuit is accomplished alarm decision according to predefined actuation of an alarm value.
The utility model adopts regularly testing pattern, i.e. machine start shows testing result after detecting once; Get into low power consumpting state then, only start the microprocessor internal timing device and pick up counting; When timing length reaches time interval of client definition, carry out gas detection again; Like this work to greatest extent energy savings reduce power consumption, do not stop over the detection of object gas simultaneously again; In the practical application, the detection of object gas is not all will carry out all the time, and a few minutes or tens minutes are detected the purpose that once can play security monitoring fully sometimes.The time interval user that object gas detects can carry out freely setting as required; In addition; Cooperate the power management function of circuit design with the intelligence of low-power consumption, the combination of a plurality of technology is used, and the power consumption of gas detector complete machine is reduced; Dwindled the volume of solar cell, reached solar cell and Detection Circuit are integrated into the inner target of same explosion-proof casing; Having solved original solar powered gas detector must separate dress, the middle problem that is connected with cable with solar cell and gas detector, has reached and has simplified the purpose of installing, being convenient to move, practice thrift cost.
The utility model is applicable to that unmanned lacks electric power again and supplies with or the not readily accessible place of staff; Or some use or the workplace of frequent change in short-term; Or measurement point relatively disperses, the applied environment of inconvenient concentric wiring, like petroleum pipe line interface and natural gas line interface, be distributed in that backwoodsman oil field and gas field etc. are local, the place of oil well probing; The utility model saves the wiring link, and improve work efficiency and reduced construction cost again, and also easy to maintenance, during use, the attention assurance sun can shine and get final product, and also can normally monitor 48 hours even without sunlight.
Should be noted that at last: above embodiment only in order to the explanation the utility model technical scheme but not to its restriction; Although with reference to preferred embodiment the utility model has been carried out detailed explanation, the those of ordinary skill in affiliated field is to be understood that: still can make amendment to the embodiment of the utility model perhaps is equal to replacement to the part technical characterictic; And not breaking away from the spirit of the utility model technical scheme, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
