According to the system, whether wireless remote cheating behavior occurs in a weighing process is judged by monitoring excitation voltage of a measuring circuit of the electronic scale, and an alarm is sent, so that the wireless remote cheating phenomenon is effectively prevented. The system has the advantages of simple structure, easiness in implementation, low cost, high measuring accuracy and reliability and the like.
Description
Technical field
The utility model belongs to electronics and communication technical field, relates to the anti-wireless remote control cheat monitoring system of a kind of electronics weighing apparatus.
Background technology
The electronics weighing apparatus is as a kind of weighing apparatus; Has the weighing precision height; Advantage such as convenient to use is widely used in the various occasions of weighing, like the weighing in the weighing of energy exploitation, the steel manufacture process; And in the transportation of the deposit of materials such as building, constructing road, in the production of grain secondary product and the processing or the like.In recent years; The quick growth of domestic economy, trade activity make that frequently the material flow flux is increasing; Under the ordering about of interests, make various electronics weighing apparatus cheatings in commerce clearing weighing process, to have occurred, these illegal row have caused great harm for both parties and even entire society.In various electronics weighing apparatus fraudulent meanses, especially with the most difficult strick precaution of electronics weighing apparatus wireless remote control fraudulent means.Electronics weighing apparatus wireless remote control fraudulent means is that certain that be employed in the electronics weighing apparatus only or on several sensor signal cables installs remote-receiver additional; And in the weighing process; Through remote controllers use remote-controlled launcher people for a change resistance of sensor and voltage; Thereby change the value of sensor, reach the purpose that changes the data of weighing.This fraudulent means is very hidden, and use at ordinary times is difficult for being discovered, and mainly shows: 1. disguised, the telechiric device that installs additional is positioned to be claimed to find than difficult below the body; 2. instantaneity only when weighing material, is taken advantage of the occasion to practise fraud by the cheating personnel at the scene, is difficult to find.Therefore, we will enhance your vigilance to this mode, draw attention.
The reception of high-frequency signal that electronics has weighed " wireless cheating " techniques make use, the corresponding cheating system of control of decoding therefore have stronger instantaneity, and cheating system composition itself simply, and it is convenient to control, and is difficult to come to light, so harmfulness is big especially.Avoid this kind cheat method, in using installation process, will strictly take precautions against and in use strict supervision, should on manufacturing technology, increase anti-cheating system simultaneously, make cheating device can not insert electronics weighing apparatus weighing system, produce when perhaps inserting and report to the police.
Summary of the invention
The technical matters that the utility model will solve provides the anti-wireless remote control cheat monitoring system of a kind of electronics weighing apparatus; This system is through the driving voltage of monitoring electronics weighing apparatus metering circuit; Judge the generation whether the wireless remote control cheating is arranged in weighing process; And produce warning, thereby prevent the generation of wireless remote control cheating effectively.
The technical scheme of the utility model is following: the anti-wireless remote control cheat monitoring system of a kind of electronics weighing apparatus, it is characterized in that, and comprise analog to digital conversion circuit, voltage conversion circuit, warning circuit, reset circuit, voltage monitoring microprocessor and computing machine; Described analog to digital conversion circuit, voltage conversion circuit, warning circuit and reset circuit all are connected with described voltage monitoring microprocessor; Described voltage conversion circuit is connected with described computing machine; Described voltage monitoring microprocessor changes circuit through described voltage dress and gives described computing machine with data transmission.Described voltage monitoring microprocessor adopts the AT89C2051 single-chip microcomputer.
The beneficial effect of the utility model: native system is judged the generation whether the wireless remote control cheating is arranged, and is produced warning through the driving voltage of monitoring electronics weighing apparatus metering circuit, thereby prevents the generation of wireless remote control cheating effectively in weighing process.Native system is simple in structure, be easy to realize, has that cost is low, measuring accuracy and a reliability advantages of higher.
Description of drawings
Fig. 1 is the structured flowchart of the utility model; Fig. 2 is a voltage monitoring circuit overall construction drawing among the utility model embodiment 1.
Embodiment
Embodiment 1: as shown in Figure 1, the anti-wireless remote control cheat monitoring system of a kind of electronics weighing apparatus is characterized in that, comprises analog to digital conversion circuit, voltage conversion circuit, warning circuit, reset circuit, voltage monitoring microprocessor and computing machine; Described analog to digital conversion circuit, voltage conversion circuit, warning circuit and reset circuit all are connected with described voltage monitoring microprocessor; Described voltage conversion circuit is connected with described computing machine; Described voltage monitoring microprocessor changes circuit through described voltage dress and gives described computing machine with data transmission, and described computing machine can be realized functions such as monitoring display as host computer.
Seeing that the cheating mode of wireless remote control cheating system is that instantaneous change LOAD CELLS driving voltage reaches the purpose that changes weigh in the weighing measurement process; Therefore design auxiliary anti-cheating Circuits System a--voltage monitoring circuit; Driving voltage through monitoring electronics weighing apparatus metering circuit; Judge the generation whether the wireless remote control cheating is arranged in weighing process, and produce warning, thereby prevented the generation of wireless remote control cheating effectively.This circuit is a core with the AT89C2051 single-chip microcomputer, mainly is made up of mould/number conversion circuit and monitoring alarm circuit two parts.
Electronics weighing apparatus voltage monitoring circuit overall construction drawing is as shown in Figure 2: at first; Modulus conversion chip ADC0832 is converted into the digital voltage signal that single-chip microcomputer can be discerned with the analog stimulus voltage signal of electronic vehicle weighing apparatus LOAD CELLS; Through the AT89C2051 single-chip microcomputer voltage signal is gathered in real time then; And signal is transformed device through MAX232 voltage be sent to monitoring equipment (computing machine), thereby judge accurately and timely in the electronic vehicle weighing apparatus weighing process that driving voltage is whether in the boundary of regulation.If the not potential pulse in the regulation compass appears suddenly in weighing measurement voltage; Then showing has in the instantaneous access electronic vehicle weighing apparatus of the cheating equipment weighing measurement circuit; This moment, observation circuit interrupted through Single-chip Controlling Realtime Alerts and reset operation; Remind the related personnel that the circuit of electronics weighing apparatus is carefully checked simultaneously, get rid of the wireless remote control cheating device.
