Description
Technical field
The utility model relates to automobile weighing measurement field, is specially a kind of full-automatic electronic truck scale.
Background technology
Electronic vehicle weighing apparatus is the metering outfit of vehicle of auto transportation being carried out weighing; Traditional electronic vehicle weighing apparatus needs stationary vehicle on weighing table; Treat that weight data reads after stable; Then by license number, the Description of Goods of manual work input vehicle, send out (to) information such as manifest position, thereby accomplish the computation weigh task one time.In the transportation of big flow and line production, there is tangible bottleneck in the link of weighing, seriously restricting normal transportation logistics speed.
The utility model content
The technical matters that the utility model solved is to provide a kind of full-automatic electronic truck scale, to solve the problem in the above-mentioned background technology.
The utility model solves the technical scheme that its technical matters adopted: full-automatic dynamic electric automobile balance; Comprise the vehicle of weighing, weighing table, weighing instrument and computing machine, the weighing table below is provided with weighing instrument, and the output terminal of weighing instrument connects input end and computer; The vehicle of weighing acts on weighing table; In vehicle one side of weighing electronic tag is set, in electronic tag the place ahead reader is set, the output terminal of reader connects input end and computer through the RS232 serial line interface.
Adopt radio RF recognition technology; Electronic tag is placed the assigned address of the vehicle of weighing; Reader is connected with computing machine through the RS232 serial line interface, reads the identification code of vehicle in the electronic tag through Programming Computer, thereby discerns the out of Memory of the vehicle of weighing; Like vehicle number, Description of Goods, place of delivery, place of receipt, driver etc., these information and vehicle weight constitute complete computation weigh information.
Radio RF recognition technology (RFID) is a kind of non-contacting automatic identification technology, and its ultimate principle is to utilize the transport property of radiofrequency signal and space coupling (inductance or EM coupling) or radar reflection, realizes being identified the automatic identification of object.(RFID) system comprises electronic tag and reader two parts.The RFID reader carries out radio communication through antenna and RFID electronic tag, can realize the read operation of tag recognition sign indicating number.
Gather other information of the vehicle of weighing for ease, described reader one is a side that can be fixedly set in weighing table, the corresponding setting with electronic tag of reader, fixedly Information Monitoring; Can also reader be connected the RS232 serial line interface through cable in addition, can hand mobile collection.
The beneficial effect that the utility model full-automatic electronic truck scale is had is: through traditional detection system of being made up of weighing table, LOAD CELLS, weighing instrument, computing machine of weighing is set; Weight to load-carrying vehicle is obtained; Utilize current state-of-the-art radio RF recognition technology to discern the out of Memory of the vehicle of weighing (like vehicle number, Description of Goods, place of delivery, place of receipt, driver etc.) automatically simultaneously; Realize the automatic dynamic weighing, the vehicle of promptly weighing does not need on table top, to stop, and at the uniform velocity passes through table top with certain speed; The weight of haulage vehicle, license number, Description of Goods, send out (to) information such as manifest position is automatically recognized; Thereby accomplish weighing process automatically one time, simple to operation, save the labour.Through on-the-spot actual test, the static truck scale that the efficiency ratio of weighing is traditional improves more than 10 times, and practices thrift a large amount of labour costs.
Description of drawings
Fig. 1 is the electrical principle block scheme of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the weighing table below is provided with weighing instrument, and the output terminal of weighing instrument connects input end and computer, and the vehicle of weighing perhaps is statically placed in weighing table at the uniform velocity through weighing table.In automobile one side electronic tag is set, in the place aheads such as electronics marks reader is set, the output terminal of reader connects input end and computer through the RS232 serial line interface.
Weighing table is selected SCS-D type digital weighing table top for use, and after vehicle sailed weighing table into, weighing table was attached thereto the senser element that connects, and the perception weight information converts electric signal into by sensor, and sensor output signal is a digital signal.
Weighing instrument is selected TP-800D digital weighing controller for use, and the digital signal of TP-800D receiving sensor output converts gravimetric value after treatment into and shows, and is connected with computing machine through serial line interface.Weighing instrument also has functions such as angular difference adjustment, linear compensation, Error processing, intelligent management.
Reader adopts the RFID reader, and composition radio frequency identification system such as electronics mark: reader is selected general low frequency induction device for use, and frequency of operation is from 120kHz to 134kHz, and electronic tag is the passive electronic tag.The RFID reader carries out radio communication through antenna and RFID electronic tag, can realize the read operation of tag recognition sign indicating number.Electronic tag places the assigned address of vehicle, and record is like information such as vehicle number, Description of Goods, place of delivery, place of receipt, drivers.The placement location of reader can have two kinds, can be provided with as required: the one, can be fixedly set in a side of weighing table, the corresponding setting of reader, fixedly Information Monitoring with electronic tag; Can also reader be connected the RS232 serial line interface through cable in addition, can be through artificial hand-held mobile collection information.
Computing machine is selected ordinary PC for use or under the relatively poor environment of condition, is selected industrial computer for use.
Principle of work and use: when the vehicle of weighing at the uniform velocity passes through weighing table, perhaps be statically placed in weighing table, weighing table is attached thereto the senser element perception weight information that connects, and converts electric signal into by sensor.Reader reads the recorded information of electronic tag.Computing machine is connected with the RFID reader with weighing instrument respectively through serial port (last, the COM2 of COM1, rs-232 standard), reads the out of Memory of weight information and vehicle respectively, thereby accomplishes the Weighing process one time.
More than show and described ultimate principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the instructions that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
