Abstract
The utility model discloses an intercity coach load monitoring device based on a single-chip microcomputer, which is characterized by comprising a photoelectric sensor mounted on a coach. An analog-digital converter which is connected with the single-chip microcomputer is further connected to the photoelectric sensor, and an audible and visual alarm, a liquid crystal display and a stepping motor are connected to the single-chip microcomputer. By means of the coach load monitoring device, operating states of the coach can be monitored timely, corresponding treatment measurements can be provided for the overload coach, and supervision of traffic administration departments and long-distance passenger transportation enterprises is guaranteed while overload transportation of the coach is prevented.
Description
Technical field
The utility model relates to a kind of long-distance bus passenger capacity monitoring device, relates in particular to a kind of SCM Based long-distance bus passenger capacity monitoring device.
Background technology
The middle-long distance passenger traffic plays a part very important in the highway communication transportation, but in actual operation process, the operator tends to seek very small profits, in the operation way, has the overcrowding situation of vehicle to take place often, has produced great hidden to transporting safely.This has not only brought economic loss to operator, make troubles to transport administration, and the most serious be that the security of the lives and property to the passenger produces huge threat.Investigation according to authoritative department shows that the first hidden danger of safety of middle-long distance passenger vehicle transportation is exactly the overload operation of vehicle.Therefore, in the operation process of middle-long distance passenger vehicle, strict control vehicle passengers quantity under steam prevents that vehicle is overcrowding, is to solve middle-long distance passenger traffic safety key of problem.
For traffic management system and middle-long distance passenger traffic enterprise, commerial vehicle is a thorny thing in operation management midway.Even the generation that can not stop overload potential safety hazard at operation starting point, terminal point and safety check website that some is set midway.Therefore, be badly in need of a kind of safety monitoring assembly, this device can in time be monitored the service condition of passenger vehicle, and to the overload passenger vehicle measures areput is provided, and is preventing that passenger vehicle from transfiniting in the transportation, also gives security for the supervision of traffic management system and public passenger transport enterprise.
Summary of the invention
The purpose of the utility model is, a kind of SCM Based long-distance bus passenger capacity monitoring device is provided, and this device can be monitored the Ferry Status of middle-long distance passenger vehicle, guarantees passenger safety.
In order to realize above-mentioned task, the utility model adopts following technical solution to be achieved:
A kind of SCM Based long-distance bus passenger capacity monitoring device; It is characterized in that comprise vehicle-mounted opto-electronic pickup, opto-electronic pickup is connected with A and D converter; A and D converter is connected with micro controller system, on micro controller system, also is connected with combined aural and visual alarm, Liquid Crystal Display (LCD) and stepping motor.
Other characteristics of the utility model are:
Said micro controller system is the AT89C51 micro controller system.
Said A and D converter is the ADC0809 conv.
Said sensor is a M18 diffuse reflection type photoelectric switch.
The SCM Based long-distance bus passenger capacity monitoring device of the utility model can in time be monitored the service condition of passenger vehicle, and to the overload passenger vehicle measures areput is provided.
Description of drawings
Fig. 1 is the hardware block diagram of the utility model.
Fig. 2 is the counting module program flow diagram.
Fig. 3 is the micro controller system main program flow chart.
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
The specific embodiment
Referring to Fig. 1; Present embodiment provides a kind of SCM Based long-distance bus passenger capacity monitoring device; Comprise vehicle-mounted opto-electronic pickup; Opto-electronic pickup is connected with A and D converter, and A and D converter is connected with micro controller system, on micro controller system, also is connected with combined aural and visual alarm, Liquid Crystal Display (LCD) and stepping motor.
In the present embodiment, opto-electronic pickup is to adopt the variation that converts measured variation to optical signal, further converts optical signal to electric signal by photounit then, promptly carries out the conversion of electric signal-optical signal-electric signal.It generally is made up of light source, optical path and photounit 3 parts.Through analyzing relatively, select M18 diffuser reflection type photoelectric switch (the NPN aerotron drives output), it can realize required basic function, simultaneously low price.In the M18 photoelectric switch, the diameter of MI8 diffuser reflection type photoelectric switch is 18mm, needs only the circular hole that on device housings, bores Φ 18mm, dark 75mm in the time of fixedly; Relay indicating light is arranged behind; LED red when detecting object lights, and is at ordinary times and extinguishes state, and its wire length is 100mm.
The actuating unit of this monitoring device is a stepping motor, mainly is to realize the forbidden of overcrowding vehicle through the binodal Valves Technology.Be equipped with on the car of ASR, the mechanical connection from Das Gaspedal to the spark ignition engine throttle gate (diesel engine fuel injecting pump lever) is got by the EML Electronic Throttle Control device and is replaced.When sensor is delivered to control unit of engine (ECU) with the position of Das Gaspedal and wheel speed signal; Control unit will produce the control voltage signal; Stepping motor signal is according to this readjusted the position (the perhaps position of diesel engine control bar) of throttle gate; Then this position signal is fed back to micro controller system, so that in time adjust drg.
When carrying out the personnel amount statistics, need carry to accomplish its tally function.
Because the passenger capacity of long-distance bus only adopts two counting systems, so the program flow diagram of counting module is as shown in Figure 2.
Though accomplished building of hardware system, let it play due effect, accomplish the function of monitoring device when the design original intention, will lean on the compiling of software to come concrete realization, the main program flow of passenger capacity monitoring device is as shown in Figure 3.
In the operation process of middle-long distance passenger vehicle, judgement is added up and made to monitoring device to occupant's quantity, and when when overcrowding situation takes place vehicle, micro controller system is carried out " forbidden " instruction to vehicle, prevents the operation of overcrowding vehicle.When only when occupant's quantity is satisfactory, micro controller system is removed after " forbidden " instruction, and vehicle can go, and has so fundamentally solved the problem that the middle-long distance passenger carriage overloading is runed effectively.
The SCM Based long-distance bus passenger capacity monitoring device of the utility model can in time be monitored the service condition of passenger vehicle, and to the overload passenger vehicle measures areput is provided.Preventing that passenger vehicle from transfiniting in the transportation, also gives security for the supervision of traffic management system and public passenger transport enterprise.
