Abstract
The utility model discloses a freight train blind area detection device, this freight train blind area detection device include ultrasonic sensor, it is provided with two respectively in the both sides of freight train, install the pressure switch on the wheel of freight train both sides respectively, and pressure switch is connected with the ultrasonic sensor of homonymy, the collection module who is connected with ultrasonic sensor, the P L C of being connected with collection module, and the alarm device who is connected with P L C, the utility model discloses an install ultrasonic sensor in freight train both sides, when detecting the freight train and turn by a wide margin, ultrasonic sensor on the freight train starts, and ultrasonic sensor begins to gather information transfer and gives P L C, then P L C calculates back feedback data and gives alarm lamp and bee calling organ, reminds the freight train driver in time to make the adjustment to security when improving the freight train and turning reduces the probability that the car accident takes place.
Description
Technical Field
The utility model relates to an ultrasonic detection technical field specifically is a freight train blind area detection device.
Background
During the running process of the truck, especially during turning, a large-range blind area is formed on the left side and the right side of the truck. If people or objects entering the blind area cannot keep enough safe space, traffic accidents are easy to happen. In order to reduce the potential hazard of blind areas during turning, most truck drivers remind nearby vehicles and pedestrians in modes of whistling, decelerating, and the like. However, the driver of the truck cannot know whether pedestrians and vehicles are in the blind area, and the method of whistling, decelerating and the like is not good.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a freight train blind area detection device, security when improving the freight train and turning.
In order to solve the technical problem, the utility model discloses a following technical scheme:
a truck blind spot detection device, comprising:
two ultrasonic sensors are respectively arranged on two sides of the truck;
the pressure switches are respectively arranged on one wheel at two sides of the truck and are connected with the ultrasonic sensors at the same side;
the acquisition module is connected with the ultrasonic sensor;
p L C connected with the acquisition module;
and an alarm device connected with the P L C.
In the above technical scheme:
the pressure switch can detect the change of wheel pressure when the vehicle turns, thereby turning on the ultrasonic sensor. The selection of pressure switches is conventional in the art.
The ultrasonic sensor is used for transmitting and receiving ultrasonic signals, so that the distance between the sensor and vehicles, pedestrians on the left side and the right side of the truck is measured, and the measured data are transmitted to the acquisition module through analog signals. The ultrasonic sensor is preferably a dual probe ultrasonic sensor.
The P L C is preferably Siemens S7-300, the type of the acquisition module is preferably EM235, the acquisition module performs A \ D conversion on acquired analog signals, and the converted data are sent to P L C for processing.
The alarm device is L ED lamp and/or buzzer, and P L C judges that the vehicle or pedestrian enters the dangerous area by analyzing the measured data of the ultrasonic sensor, thereby triggering the alarm device and sending an alarm signal to the driver of the truck.
The utility model has the advantages that:
the utility model discloses an at freight train both sides installation ultrasonic sensor, when detecting the freight train and turn by a wide margin, ultrasonic sensor on the freight train starts, and ultrasonic sensor begins to gather information transfer and gives P L C, then P L C calculates back feedback data and gives alarm device, reminds the freight train driver in time to make the adjustment to security when improving the freight train and turning reduces the probability that the traffic accident takes place.
Drawings

Fig. 2 is a circuit diagram of the acquisition module of the present invention.
Fig. 3 is a circuit diagram of P L C according to the present invention.
Detailed Description
The present invention is described below with reference to the accompanying drawings, and the specific embodiments described herein are only used for illustrating and explaining the present invention, and are not used for limiting the present invention, and various modifications and improvements made by those skilled in the art to the technical solution of the present invention should fall into the protection scope of the present invention without departing from the design spirit of the present invention.
As shown in FIG. 1, the dead zone detection device for the truck of the embodiment comprises two ultrasonic sensors which are respectively arranged on two sides of the truck, pressure switches which are respectively arranged on one wheel on two sides of the truck and are connected with the ultrasonic sensors on the same side, an acquisition module connected with the ultrasonic sensors, a P L C connected with the acquisition module, and an alarm device connected with the P L C, wherein the ultrasonic sensors are double-probe ultrasonic sensors.
As shown in fig. 2, the ultrasonic sensor of this embodiment is connected to P L C through an analog expansion module EM235, the EM235 is used as an acquisition module, the EM235 module can realize 4-way analog input, that is, simultaneously access four ultrasonic sensors US1, US2, US3, and US 4. specifically, one port of the signal output end of the ultrasonic sensor is simultaneously accessed to an RX end and an X + end (X represents A, B, C and D in the drawing, respectively), and the other end is accessed to an X-end.
As shown in fig. 3, the P L C type of the present embodiment is cpu226xp in siemens S7-300 series, the alarm device is two L ED lamps and a buzzer, the two L ED lamps are respectively connected to Q0.0 end and Q0.1 end of P L C, the buzzer is connected to Q0.3 end, and a L ED lamp for displaying whether a line is faulty is connected to Q0.2 end, the two L ED lamps are respectively used for alarming on left and right sides of a truck, the P L C calculates a distance between a detected object on the side and the truck according to measurement data of the two ultrasonic sensors on the same side, and triggers the L ED lamp and the buzzer for warning when the distance is within a preset dangerous distance, so as to remind a truck driver of timely making an adjustment.
