City road tail gas supervising device based on well lid
Technical field
The utility model relates to road tail gas monitoring technique field, particularly a kind of city road tail gas supervising device based on well lid.
Background technology
Along with scientific and technological development, be also accompanied by the destruction of environment, in order to ensure the quality of people's living environment, all need to monitor the air quality data in each section, take corresponding environmental protective measure that foundation is provided in order to environmental management personnel to this region.But, existing road Detection of Air Quality is all that the detecting device by being arranged on the electric pole of roadside detects, it detects poor effect, and precision is not high, because the pollution main source of road air is the discharge of vehicle exhaust, and the weight of vehicle exhaust is all than oxygen weight, therefore, there is error for the detection of tail gas in existing checkout equipment.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of city road tail gas supervising device based on well lid, can realize based on well lid the collection of road air, to send to remote monitoring center, accomplishes the monitoring of road vehicle exhaust.
The utility model adopts following scheme to realize: a kind of city road tail gas supervising device based on well lid, comprise square palisade well lid, it is characterized in that: also comprise the scavenger fan and the waterproof mounting box that are arranged at described square palisade well lid below, in described waterproof mounting box, be provided with a circuit board, described circuit board is provided with lithium battery and a MCU for this circuit board power supply, and described MCU is connected with Detection of Air Quality sensor, scavenger fan driving circuit and wireless communication line; The described output terminal of scavenger fan driving circuit and the control end of described scavenger fan are connected.
In the utility model one embodiment, described MCU is also connected with a storer.
The utility model system architecture is simple, makes full use of the vantage point of well lid, and road tail gas is carried out to remote monitoring, and not only monitor data is accurate, and arrangement convenience, does not take road space, does not affect traffic.
Brief description of the drawings
Fig. 1 is that the utility model pick-up unit is arranged at the view on well lid.
Fig. 2 is the circuit catenation principle schematic diagram of the utility model test side.
Wherein, 1 is square palisade well lid, and 2 is scavenger fan, and 3 is wire, and 4 is waterproof mounting box.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As depicted in figs. 1 and 2, the present embodiment provides a kind of city road tail gas supervising device based on well lid, comprise square palisade well lid 1, it is characterized in that: also comprise a remote monitoring center and be arranged at scavenger fan 2 and the waterproof mounting box 4 of described square palisade well lid below, in described waterproof mounting box, be provided with a circuit board, described circuit board is provided with lithium battery and a MCU for this circuit board power supply, and described MCU is connected with Detection of Air Quality sensor, scavenger fan driving circuit and wireless communication line; The described output terminal of scavenger fan driving circuit and the control end of described scavenger fan are connected.
In order to allow those skilled in the art better understand hardware characteristics of the present utility model, describe below in conjunction with use-pattern.The utility model MCU sends to remote monitoring center by data through wireless communication module.Described MCU receives the detection instruction of described remote monitoring center, first starts after described one schedule time of scavenger fan, then gathers the data of described Detection of Air Quality sensor, then these data is sent to described remote control center through wireless communication line.
In order to improve the accuracy of data, the present embodiment proposes, be connected with a storer at described MCU, after described detection instruction triggers, enter Detection of Air Quality flow process, this testing process comprises the detection of pre-determined number, and described MCU is stored in the detection data of this pre-determined number in described storer, and after weighted mean, send to remote monitoring center.It is worth mentioning that, in the present embodiment, each detect all between at regular intervals.
Whether can know test side for the power down mode of guarantee system the best and remote control center and normally work, described MCU, every a schedule time, sends a heartbeat message to described remote control center.In test side, not in the time detecting, system is in holding state, fully to ensure the service time of electric energy.If be provided with cable under well lid, can also remove electricity through cable.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
