Abstract
The invention discloses an automatic bus overload alarm device comprising a detection sensing module, a single-chip microcomputer, a display alarm module and a key module. The detection sensing module comprises two sensors used respectively for boarding detection and alighting detection. Signals detected by the sensors are transmitted to the single-chip microcomputer for processing, and obtained data are transmitted to the display alarm module. The display alarm module comprises a digital tube displaying the number of people in a bus currently, a photodiode indicating the current load condition of the bus, and a buzzer warning for overloading. The key module comprises five function keys. The automatic bus overload alarm device according to the technical scheme is simple, handy, low in production cost and suitable for large-area popularization.
Description
Technical field
The present invention relates to the automatic checkout equipment technical field, is a kind of passenger carriage overloading autoalarm specifically.
Background technology
Nowadays passenger vehicle has become the important tool of people's trip and tourism, and still, along with the increase of passenger flow volume, the phenomenon of overload is also day by day serious, and this will cause certain potential safety hazard to driving.In order effectively to avoid the generation of this type of phenomenon, the device that designs a set of overload detection will be a kind of trend.Still do not have at present simple and practical.The automatic detection alarm device that the cost cost is low, be suitable for spread.
Summary of the invention
The objective of the invention is, for above-mentioned deficiency of the prior art, provides a kind of scheme simple and practical, cheap passenger carriage overloading autoalarm.
The objective of the invention is to be achieved through the following technical solutions:
A kind of passenger carriage overloading automatic detection alarm device, this device comprises the detection sensing module, micro controller system, display alarm module and key-press module, described detection sensing module is comprised of two sensors that detect that are respectively used to get on the bus and get off, the signal that described sensor detects is passed to micro controller system and is processed, the data that obtain are passed to described display alarm module, described display alarm module comprises that demonstration works as the charactron of number on front truck, the light-emitting diode of the carrying situation that the reflection passenger vehicle is current and the buzzer phone of overload warning, charactron adopts the double figures code to manage current seating capacity in real-time demonstration passenger vehicle, light-emitting diode comprises the normal green indicating lamp of vehicle-mounted number, amber light in the red alarm lamp of overload and the number of adjustment higher limit process.When overload red light can glimmer and buzzer phone warnings that can intermittently pipe, recover normal when passenger capacity and just only have green light bright later.Key-press module comprises five function buttons.
Post-processed for convenient signal, described detection sensing module also comprises amplifying circuit, the signal that described sensor detects is first passed to described micro controller system again and is processed after amplifying circuit amplification and analogue to digital conversion, amplifying circuit is except amplifying signal, also has analogue to digital conversion, the output low and high level.
Further in scheme, described micro controller system has been used low-power consumption, performance-oriented 51 series monolithics, except incoming signal is processed and signal feedback output, also increased the key-press module that the passenger vehicle seating capacity upper limit arranges function has been set, to the passenger vehicle of being transplanted to different passenger capacity, provide convenience.
For improving the accuracy rate detected, described sensor is that heat is released infrared sensor of the human body, heat is released the employing of human body infrared detecting sensor, and to Infrared, the most responsive light sensor detects the infrared ray of human body radiation with the noncontact form, and change it into voltage signal, with traditional detecting device, compare more accurate, avoided people and thing regardless of the false retrieval phenomenon
Described sensor also can be provided with Fresnel Lenses, makes its sensitivity higher, but also has in addition repeated trigger and two kinds of patterns of not reproducible triggering optional, and it is undetected that repeated trigger has been avoided.
Concrete occupation mode is, two sensors are contained in respectively on the front and back door of passenger vehicle, when having detected that the people gets on the bus in front or having got off from back door, the signal detected is passed to micro controller system and carry out plus and minus calculation, the passengers quantity upgraded in time on car, then show the patronage on current passenger vehicle by double figures code pipe.In addition, also by indicator lamp, show the running state of current this device, amber light is bright shows to regulate the number higher limit, and green light bright showing counted, and when red shows that passenger vehicle overloads, and buzzer phone can send warning when passenger carriage overloading.Increased number and set button in data processing module, be used for regulating the number higher limit, this device can be transplanted to flexibly on the passenger vehicle of different passenger capacity.
The present invention has following outstanding beneficial effect: heat is released infrared pickoff and can well the passenger who get on or off the bus be detected, and higher accuracy of detection is arranged; Number on front truck is shown having increased charactron aspect the information feedback, can allow passenger and driver clearly know the number situation on front truck; In addition button alerting ability and the portability that has strengthened this application of installation be set, passenger carriage overloading automatic detection alarm device scheme of the present invention is simple and practical, cheap, has very large promotional value.
The accompanying drawing explanation
Fig. 1 is passenger carriage overloading automatic detection alarm device configuration schematic diagram of the present invention; .
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Referring to Fig. 1, two sensors 8 is installed on respectively the passenger vehicle front/rear door, be mainly used to detect two whether passenger getting on/off is arranged and signal conversion is amplified after send micro controller system 2 to, wherein the power supply of detection module 1 is provided by micro controller system 2 system modules.The data that 2 pairs of detection modules 1 of micro controller system transmit are processed and judged gets on the bus or gets off, and count value is added to 1 if get on the bus, otherwise subtracts 1.After micro controller system 2 statistical treatments, count value is shown by charactron 4.Three indicator lamp Huangs, green, the red current state that is used to refer to, be respectively and regulate number higher limit, passenger vehicle not overload condition, passenger carriage overloading state.When passenger carriage overloading, buzzer phone 6 will send warning.Key-press module 7 has five buttons as shown in Figure 1, and from left to right the function of each button is respectively: key, number upper limit increase key, number upper limit minimizing key, setting check key, reset key are set.
Be more than preferred embodiment of the present invention, all changes of doing according to technical solution of the present invention, when the function produced does not exceed the scope of technical solution of the present invention, all belong to protection scope of the present invention.
