Device.
Background technology
Weighbridge, is provided in the large-scale weighing machine on ground, is generally used for weighing to vehicle and contained goods.Weighbridge is made
For a kind of weighing-appliance, the occasion that storehouse, factory building etc. need to weigh is widely used in.
In the costly occasion of some materials, criminal remotely changes weight bridge weighing result using high-tech means, with
The situation for obtaining unlawful interests happens occasionally.Cribber installs wireless electron remote-receiver additional on weighbridge, when vehicle weighs
When, by the Digiplex in starting（The wireless electron remote-receiver and Digiplex are referred to as device of practising fraud）, over the ground
The weighing results of pound are arbitrarily added and subtracted, so as to obtain unlawful interests.
For such case, increasing enterprise is after buying weighbridge now, and can all purchase again a set of prevents weighbridge
The instrument being remotely-controlled, to ensure Numerical accuracy during weight bridge weighing work, such instrument is commonly referred to as measuring prevention and control instrument,
It is mainly used for the electromagnetic wave of transmitting frequency same with cheating device, the signal for device of practising fraud is disturbed, to avoid weighbridge quilt
Cheating device remote control and distort the metering numerical value of weighbridge.
Present weighbridge cheating device, is the weighing results for the radio change weighbridge for launching fixed frequency, such as 315MHz mostly
Or 433MHz.Later cribber, changes tranmitting frequency, and the method for radio is launched using frequency conversion, gets around and disturbs larger frequency
Rate, to reach the purpose of cheating.Still later, some cribbers, increase fixed frequency（Mainly 315MHz and 433MHz）'s
The transmission power of radio, to overcome interference, reaches the purpose of cheating.Existing metering prevention and control instrument, generally comprises peripheral module,
Function to realize alarm, display, input order；Power module, is that other need the module for power supply of electric power；Radio mould
Block, to receive and launch radio.
Existing metering prevention and control instrument, is the cheating device for being merely able to disturb low power fixed frequency mostly, and some meterings are prevented
Control instrument can interfere with the radio cheating device for being capable of frequency conversion, and also no one kind can either disturb powerful fixed frequency
（315MHz and 433MHz）Cheating device, other frequency conversions are can interfere with again and are practised fraud the metering prevention and control instrument of devices.
Utility model content
The utility model, which provides one kind, can either disturb powerful fixed frequency（315MHz and 433MHz）Cheating
Device, can interfere with the metering prevention and control instrument of other frequency conversions cheating devices again.
The utility model provide base case be：Prevention and control instrument is measured, including：
