Further, video monitoring apparatus is set near weighing platform, is used to monitor vehicle and personnel's situation on weighing platform and the weighing platform, and monitor data is transferred to described computing machine.
Further, described weighing sensor is a digital transducer.
Further, at each weighing sensor by different communication protocol transmission signals.
Further, be that weighing sensor is protected by the closed package structure to the data bus connection between the computing machine at least.
Further, the continuous data of storing in the computing machine can not be modified and delete, the daily record of work of computer recording metering system.
Further, warning device is by voice signal and/or luminous signal and/or dial and report to the police.
Further, near the weighing sensor at least of electronics weighing apparatus and the line thereof proximity transducer is set and is used to survey the illegally approaching of lawless people, when detect illegally near the time, proximity transducer triggers warning device by computing machine and reports to the police.
After adopting said structure, the trailing wheel that can prevent vehicle in weighing process not exclusively on weighing platform or front-wheel surpasses weighing platform and make metering result situation less than normal occur, page or leaf can prevent that in weighing process two drivers gang up back first car on weighing platform during weighing, the back vehicle front-wheel is also gone up the weight metering result situation appearance bigger than normal that weighing platform causes, and can prevent the destruction of illegal molecule to sensor and cable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail: as shown in Figure 1, the system of the utility model electronics weighing apparatus forms infrared sensor, video monitoring apparatus, proximity transducer, weighing sensor, display interface, vehicle clearance device and the warning device that comprises computing machine, PLC control.
Computing machine be responsible for other building blocks of control system cooperating, store the data that each building block gathers, the Operation Log of register system.
The infrared sensor of PLC control is used to judge whether vehicle all is positioned at weighing platform as requested, the two infrared correlation systems that are arranged on the weighing platform rear and front end are as infrared sensor, when infrared correlation system is under the situation of on-state, system's work of just can weighing normally, when vehicle front-wheel or trailing wheel are not parked on the weighting platform but between the edge of weighting platform and ground fully, computing machine can be pointed out or control system will not be weighed by warning device, when infrared correlation system is under the situation of fault or off-state, system can point out and will not weigh by warning device.
Before and after infrared correlation system be provided with can prevent vehicle in weighing process trailing wheel not exclusively on weighing platform or front-wheel surpasses weighing platform and make metering result situation less than normal occur, page or leaf can prevent that in weighing process two drivers gang up back first car on weighing platform during weighing, and the back vehicle front-wheel is also gone up the weight metering result situation appearance bigger than normal that weighing platform causes.
Proximity transducer among Fig. 1 is used to survey the lawless person to being arranged on the illegally approaching of near the electronic loadometer electronic circuit and sensor, selecting proximity transducer among this embodiment is infrared eye, be arranged near the weighing sensor, video monitoring apparatus, electronic circuit of electronic loadometer, as long as lawless person one does not allow other people approaching electronic installation and circuit near pound body and other, infrared eye will detect and report to the police by warning device, in time notify operator on duty or related work personnel to call a halt, prevent the generation of cheating in advance.
As shown in Figure 1, warning device can be sound and/or luminous and/or dialing alarm device, and for unnecessary interference, should be in the other upright warning board of electronic loadometer, in order to avoid the relevant personnel produce unnecessary warning when being not intended near the pound body.
Video monitoring apparatus is used for weighbridge and situation are on every side monitored, whether the weighman can monitor the weighing platform position of stopping of getting on the car by display interface and meet the requirements, whether the someone stands on the weighting platform in weighing process, whether the people is arranged in the pilothouse, and whether railway carriage has the cheating of article top grade weighing process when returning skin; Gross weight, net weight can only receive the weight information of weighing sensor output in the weighing process, when preserving gross weight, net weight data each time, all can get off preservation of scene photograph at that time; Like this, the photo that the car of same license plate number can access when weighing for the first time when carrying out weighing for the second time contrasts, and the weighman can see the photo when weighing for the first time and weighing for the second time.
The weighman can see that when weighing for the first time and weighing for the second time be same vehicle, can stop like this that dolly weighs, cart returns skin or cart weighs, dolly returns the such cheating of skin and takes place; Stop in the weighing process that front-wheel or trailing wheel are intact originally to be parked on the weighing platform weight such cheating that kicks the beam.
Weighing sensor in this utility model is a digital transducer, rather than traditional analog sensor, this digital transducer is directly exported digital signal by the mode of embedded digital module, carry out digital data transmission by certain communication protocol, and different sensors uses different communications protocol, thereby this has just fundamentally stopped to attempt to change the possibility that signal magnitude influences simulated sensor data output by resistance circuit in the past.Export the duty of detecting sensor in real time by digital sensor, can judge by the interior code value of checking sensor whether sensor voltage signal is changed, realize the anti-cheating function of electronic loadometer.
In order to prevent that the lawless person is by destroying and change the data transmission cable realization cheating of system; this system all adopts the closed protective device to wrap up from the data transmission cable of penetration pipe to the scale body to weight house of sensor conductor, makes by the behavior of circuit cheating to have no way of doing it.
The host computer Operational Management System that system provides has data protection function, and the record of promptly finishing of weighing no longer has the authority (comprising the modification of the data of weighing and the deletion of pound list etc.) of modification.It is with the valid data of honest and trustworthy record actual mechanical process.
System also can be provided with a threshold value (setting being set by authority); when actual weight on the scale body surpasses this threshold value; system will write down one group of data and protection automatically, and the operating position that can inquire about electronic loadometer so at any time effectively prevents the illegal use of operating personnel to electronic loadometer.
The Operation Log of computer system record metering system comprises that the user lands the time of metering system, carried out which kind of operation, the error reporting that produces in the use etc. when using metering system.Provide reliable basis to the people for cheating.
The utility model is not limited to the content of the foregoing description; present embodiment only is a kind of exemplary illustration; the simple change that those skilled in the art makes on the basis of the present utility model thought according to general knowledge also should fall into protection domain of the present utility model.
