Abstract

PURPOSE:To provide the apparatus, which can measure, detect and record overload of a truck and can issue a fare card for receiving the additional fare in correspondence with the overload. CONSTITUTION:Electromagnetic waves are emitted from the transmitting side of an identifying detector 1 with an operating panel 7 in a gate control chamber 4, and the shape, the length and the stopped position of an automobile are measured and detected. The weight is measured with a first weight measuring device 8 and a second weight measuring device 9, and the identification and confirmation of the display of the truck are performed. When the weight is excessive, the fact of the overload is notified to the driver in digital values and recorded.

Description

Detailed Description of the Invention

[Industrial field of use] Recently, overloading of cargo trucks in particular has become a problem, and owners and managers of trucks are obliged to take responsibility by laws and regulations. Is a problem with.
In addition, the increase in tolls on toll roads has become a hot topic, and it seems necessary to have a method of considering and determining a wide range of tolls for vehicles using toll roads. Nowadays, with the progress of computerization, it can be used for the production process of manufacturing in the industrial world, product management method, and measurement management of garbage incinerator.

[Prior Art] There is a measuring method for measuring the overload of a freight vehicle, but the measuring method is an important problem. A weigh scale is a measuring instrument that measures the physical quantity, which is the mass of the scale, in the basic unit, and accuracy cannot be obtained unless it is measured in a stable state. There are many problems in the conventional method of measuring the load weight of a lorry. To briefly explain this point, the measurement is unstable and accuracy cannot be obtained because the axle of the body of a freight car is mainly considered. I sometimes see police officers inspecting a lorry overweight at the gate of a highway, but for drivers who aren't overweight,
It is annoying to be put on a weighing scale and fair crackdown is necessary.

[Problems to be Solved by the Invention] Excessive loading weight of a freight vehicle causes a traffic accident, and
Road damage will also occur. This is an idea for eliminating the heavy-weight mover, and a freight vehicle and an ordinary passenger vehicle will be described separately. In the case of a freight vehicle, the vehicle body weight + the loaded weight = total weight. The total weight must be added to the weight of the lorry driver. The problem is whether the vehicle body weight + body weight = total weight, the loaded weight + body weight = total weight, or the average weight 60 kg. When the weight including the body weight is taken as the total weight, the weight when the weight measured by the weighing machine exceeds the total weight is the violating weight. Also, the mechanism of the weighing machine and the measuring method are important. When freight cars and ordinary cars use toll roads, the gate, entrance, and exit managers are particularly vulnerable to exhaust gas pollution, as more than 2000 freight cars are repeatedly started and stopped every day. . To eliminate this, I think it is necessary to issue an automatic pay card. Recently, raising the toll on toll roads has become a hot topic. In order to solve this point, I think it would be better to consider the tolls for toll roads broadly by vehicle type. For example, it is considered that there are 4 types of ordinary automobiles and 6 types of freight automobiles, and it is necessary to collect an additional fee for an overweight vehicle with an overweight amount. It is also possible to install an automatic measurement detector, a weighing machine, and an automatic fee payment machine at the garbage incineration site.

[Means for Solving the Problems]

[Fig. 1] Front view This is installed when a freight car or an ordinary car travels on a toll road or a national road. 1,3,4,7,5,6,7,

5. Operation panel, recording device 6. Stopping device when the weight of a freight vehicle is over 7. Identification confirmation of marking When the weight is over, the quantity is digitally notified to the driver and recorded. 8.9. Weighing machine 1st weighing machine, 2nd weighing machine The pressure difference measurement method and the spring deflection margin magnetic sensor common type are used for the weighing method.

[Operation]

[Fig. 2] 1. The transmitting side irradiates the receiving side of 2 with an electromagnetic wave, and the transmitting side receives the information recorded in the receiving side. You can receive detection measurements, alerts, records, fee card classifications, and other information.

[Fig. 3] Pneumatic and hydraulic pressures are sent into the cylinder at a constant pressure. Make an orifice in the cylinder to increase the flow velocity. When the weight is applied to the weigher, a pressure change occurs, resulting in a pressure difference. The method of measuring the pressure difference and the method of measuring the flexure allowance of the spring are also used, and act as a cushion.

[Embodiment] This is installed when a freight vehicle or an ordinary passenger car travels on a toll road or a national road. When a car enters the toll road, the weighing machine measures the gross weight based on the information recorded on the receiving side by the transmitting side. By knowing the vehicle body weight of the automobile, it is possible to know the measured weight−vehicle body weight = loaded weight by the weighing machine. Use at a garbage incinerator. The information recorded in the car allows a wide range of classifications of the car type to be known.

[Advantages of the Invention] In the present situation where information technology is advancing, it is possible to impartially carry out crackdown of overloaded weight of a lorry, which requires a method that can be easily managed by an administrator. It is possible to issue a car-based classification fee card and prevent pollution. It is also possible to automatically pay the automatic measurement and measurement fee at the garbage incinerator. It can be widely used in the production process of manufacturing. The number on the information license plate attached to the vehicle provides information when a stolen vehicle or a criminal escapes in a vehicle and enters a toll road or passes a national road.

Claims (4)

[Claims] 1. When installing a lorry on a controlled toll road or a national highway, when the lorry enters the toll road, the transmitter side sends electromagnetic waves to the lorry from the installed measuring device. Irradiate. The information attached to the vehicle receiving side can be received and recorded by the transmitting side.
By measuring the total weight in the case of a lorry, it is possible to digitally display and warn overweight.
Information on ordinary passenger cars is also recorded. 2. A passenger car and a freight car can be classified by vehicle type, and a toll calculation fee card can be issued. 3. It is installed when a lorry travels on toll roads and national roads, and particularly by installing the first weighing machine and the second weighing machine on the toll road, it is easy to measure the weight. Become. Pneumatic or hydraulic pressure is used for the weighing mechanism. Inject the pressure into the cylinder at constant pressure.
By making an orifice inside the cylinder, the flow velocity becomes faster. When a load is applied to the weighing machine, a pressure change occurs and the pressure increases. The increased pressure causes a bending margin of the spring simultaneously with the pressure measurement method. It is used together with the flexure allowance measurement method and acts as a cushion. Due to the heavy weight of the lorry, ensure that the weigher has an average load. Conventionally, there was no such idea when using a cylinder. 4. A detection / measuring machine is installed in a refuse incineration plant.
The vehicle body weight of the vehicle can be known from the information attached to the vehicle receiving side where the transmitting side enters. By subtracting the weight of the car body from the weight measured by the installed weighing machine, you can also pay the charge automatically according to the weight of the loaded weight.
