Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further elaborated:
Being passenger carriage overloading monitoring system structural representation shown in Fig. 1, native system is processed circuit by single-chip minimum system, infrared tube and count signal, pressure transducer, alarm form with relay, liquid crystal display circuit.Hardware includes the components and parts such as AT89C51 system, pressure transducer MPX4250, A/D conversion chip ADC0832 and display module LCD1602.Relay, speaker, LCDs electrically connect with single-chip microcomputer respectively；It is connected with single-chip microcomputer after infrared tube connection count signal processing circuit；Pressure transducer is connected with single-chip microcomputer after connecting A/D conversion chip.
Being that passenger gets on and off schematic diagram shown in Fig. 2, Fig. 3 is direction discernment circuit；
Whether the overload of intercity bus is exceeded the manned number of core by it judges, may determine that whether it overloads by gathering the get on and off method of number of motor passenger vehicle.Owing to intercity bus is during operation, the upper and lower number of passenger is continually changing, so native system must accurately judge that passenger gets on the bus or gets off and adds up.
This monitoring system passenger get on and off number judgement and statistics specific design as follows:
Having three steps at passenger door, be set to A, B, C, wherein A represents first step, and B represents second step, and C represents the 3rd step.First pair of infrared tube is placed in the place at 1.2 meters from pedal of A step high (height the child less than a meter do not count) place；Second pair of infrared tube is placed in 0.6 meter from pedal high place of C step；First set pressure transducer is placed at B step-type pedal, and the second sleeve pressure sensor is placed at C step-type pedal.Under normal circumstances, if the infrared tube at A is first triggered, then the pressure transducer at B is triggered, and when the infrared tube at C is triggered, illustrates that passenger is to get on the bus；On the contrary, the infrared tube at C is first triggered, and then the pressure transducer at B is triggered, and when being triggered after the infrared tube at A, illustrates that passenger is to get off.Under abnormal condition, such as some lawless persons deliberately individually block A or C or time two are blocked simultaneously with hands, and relay is started working, the pressure transducer entrance duty at gating C place.In this case, if the pressure transducer at B is first triggered, then the pressure transducer at C is triggered again, and passenger loading has been described；On the contrary, if the pressure transducer at C is first triggered, then the pressure transducer at B is triggered, and passenger getting off car has been described.Add up by the judgement that passenger is got on and off with to the number in car, can determine whether whether passenger vehicle overloads.
The monitoring system using single-chip microcomputer to be core can add up patronage in passenger vehicle, and is shown in real time by liquid crystal display.When overload occurs in passenger vehicle, system carries out sound and light alarm.Stoped the operation of overload passenger vehicle by the starter of cut-off passenger vehicle simultaneously.Otherwise, after overload releases, sound and light alarm is released from, and system releases the locking to passenger vehicle the most accordingly, and passenger vehicle can be properly functioning, thus reaches to monitor the requirement of passenger carriage overloading.
Fig. 4 show photoelectric sensor circuit, simulates infrared sensor by photosensitive resistive arrangement, and when not having passenger through out-of-date, owing to the resistance of illumination forceful electric power is the least, the least audion of transistor base voltage is off state, and relay A end of being failure to actuate is in high level；When having passenger through out-of-date, can block illumination, photoconductive resistance resistance increases, and transistor base voltage increases, and audion is in the conduction state, and actuating of relay A end is in low level.
Fig. 5 show warning circuit, and when in passenger vehicle, patronage exceedes default value, overload monitoring system will send warning.Use buzzer as the sounding component of acoustic alarm.When overloading occurs, single-chip microcomputer send high level instruction, drive buzzer work with audion, call time delay subroutine and make buzzer send the audio signal of 1KHZ.When number is less than default value, single-chip microcomputer sends low level instruction, and the buzzer light emitting diode that do not works is the most luminous, cancellation of i.e. reporting to the police.
Fig. 6 show relay lock circuit, when passenger carriage overloading, in order to stop passenger carriage overloading to travel, and the method usually using the electronic ignition device cutting off bus engine.AT89C51 system connects the control end of relay, drives relay work through audion, the output termination yellow light-emitting diode of relay normally open contact, the output termination red light emitting diodes of normally-closed contact.Light emitting diode is used to identify the light indication signal of relay whether action, and when relay internal switch is at normally opened contact, green diode is luminous, represents that the starter of passenger vehicle can be properly functioning；When passenger carriage overloading by the Single-chip Controlling actuating of relay, making internal switch be placed in normally-closed contact, now red light emitting diodes is bright, and red light emitting diodes lights that expression passenger vehicle is locked cannot be properly functioning.
The above, detailed description of the invention of the present utility model is only intended to describe technical scheme in detail, does not limit protection domain of the present utility model, any change made without creative work or equivalence and replaces, is all contained by this utility model.
