Description

For measuring the Intelligent preventive control method of prevention and control
Technical field
The present invention relates to weighbridge prevention and control fields, and in particular to a kind of for measuring the Intelligent preventive control method of prevention and control.
Background technique
The enterprise and factory that related to steel, coal, cement etc. need to weigh cargo at present can all use ground Pound measures.But some unprincipled fellows spare no high price to develop the device that can be remotely controlled weighbridge under the driving of interests now, The data of display can be increased or be reduced, to achieve the purpose that seek exorbitant profit.
Weighbridge mainly utilizes tabletting type sensor (strain gauge electric bridge, weight sensor or a weighing and sensing in other words Device etc.) weight that will measure, charge transport is converted into single-chip microcontroller, then equipment is shown by MCU driving one, weight is shown It shows and.Criminal changes the letter in weighbridge by between tabletting type sensor and single-chip microcontroller, filling a reception device steathily Number transmission, pass through remote controler, realize cheating.
In response to this, after purchasing weighbridge, can all purchase again a set of prevents weighbridge for more and more enterprises now The instrument being remotely controlled, to guarantee accuracy when weighbridge work, such instrument is commonly referred to as measuring prevention and control instrument, anti-prosecutor Method is the electromagnetic wave of transmitting frequency same as cheating device, is interfered the signal of cheating device, distant by cheating device to avoid weighbridge Control and distort the metering numerical value of weighbridge.
More original weighbridge cheating device is mostly the weighing results for emitting the radio change weighbridge of fixed frequency, such as 315MHz or 433MHz.Later, the case where practising fraud for this fixed frequency, market occur emitting the metering prevention and control of fixed frequency Instrument.Present cribber with the development of technology is by changing tranmitting frequency, using the side of frequency conversion transmitting radio mostly Method gets around and interferes biggish frequency (fixed frequency) range, to achieve the purpose that cheating.
The case where for present frequency conversion transmitting radio cheating, our company submitted the practical new of entitled " metering prevention and control instrument " Type patent in the program, is matched by setting receiving module with FM transmission module, i.e. change in receiving module reception environment Frequently (frequency modulation in other words) signal, after processing module is handled, allow FM transmission module emit identical with its frequency electric wave into Row interference.But in practice, it has been found that a new problem, receiving module in fact can only receive in a certain range Frequency signal, it is desirable to monitoring, the screen of the electric wave of this larger range frequency of 100-1000MHz are realized by receiving module It covers, is in fact to be difficult to realize that scanning is received within this range.
Original design mainly reaches change by inputting all kinds of configuration files in metering prevention and control instrument by user The parameter (such as inductance, impedance) of receiving module realizes the received mesh of electric wave signal of wide-band (100-1000MHz) range , but user reflects that the operation of manual loading configuration file is excessively complicated, the parameter of receiving module just seldom changes from factory Become.Therefore, we can just expect being capable of the automatically scanning (monitoring) in wide-band (100-1000MHz) range automatically by one kind Receiving module be added in our metering prevention and control instrument, after consulting pertinent literature, discovery similar approach it is considerably less, mainly It is that the processing module of present antenna relies on single-chip microcontroller mostly, but the processing capacity of existing single-chip microcontroller is limited, should bearing , can be excessive due to configuration file when duty driving display module executes scan command again, in a wider frequency range, sweep It is very slow to retouch speed.And in present environment, there is the electric wave largely interfered in the space environment as locating for us Signal, if cannot effectively be excluded, easily be reported by mistake.
In response to this, it is badly in need of a kind of intelligence for being used to measure prevention and control that can be improved scanning speed, reduce wrong report now It can preventing control method.
Summary of the invention
The present invention is directed to existing metering prevention and control instrument when executing the scanning of 100-1000MHz frequency bandwidth, scanning speed Slowly, it is easy to appear the technical issues of wrong report, is provided a kind of for measuring the Intelligent preventive control method of prevention and control.
Base case provided by the invention are as follows: for measuring the Intelligent preventive control method of prevention and control, include the following steps:
Scan receiving step, the electric wave signal in target band width be separated at least two signal frequency ranges, setting with The corresponding FM reception module of signal frequency range, FM reception module is respectively periodically to the electric wave signal in corresponding signal frequency range Continuous sampling reception is carried out, each FM reception module is connected separately with corresponding processing module, and processing module analysis is corresponding The signal strength that FM reception module receives, when the electric wave signal intensity of a certain frequency is more than threshold value, processing module is to this The electric wave signal of the frequency of point value is analyzed and processed;
It scans and determines step, if the electric wave signal long-term existence of the frequency of the integer value, determines the frequency of the integer value Electric wave signal be environmental disturbances, next period do not carry out sampling reception to the electric wave signal of the integer value frequency;If the integer The frequency signal of value only exists in weight bridge weighing, then determines the electric wave signal of the frequency of the integer value for signal of practising fraud;
The frequency for signal of practising fraud is sent transmitting module, transmitting module transmitting and work by interference preventing control step, processing module The identical interference signal of disadvantage signal frequency;
It interferes and determines step, the weight sensor of weighbridge is connect with check processing module and single-chip microcontroller respectively, in weight Memory module is provided between sensor and single-chip microcontroller, the result that memory module weighs each weight sensor is recorded, supervised After measuring cheating signal, the signal of the weight sensor received is transmitted to check processing module, check processing mould by single-chip microcontroller Block receives the feedback data of weight sensor and single-chip microcontroller respectively, if feedback data unanimously if interference signal it is effective, if feedback coefficient According to inconsistent, prove that weighing results are modified;
Warning note step checks processing module for the result and feeds back to report if there is the inconsistent situation of weighing results Alert module, alarm module issues sound-light alarm, to remind user.
The principle of the present invention and advantage are: by received target band (100-1000MHz) in scanning receiving step Electric wave signal in width is separated into multiple frequency ranges, setting FM reception module corresponding with frequency range after separation, FM reception Module respectively receives the electric wave signal in its corresponding frequency band.It is a FM reception module of setting in existing design, Reception ability, scanning speed is limited, in the present solution, multiple FM reception modules are received respectively with regard to different frequency ranges, Sweep time is reduced, the received speed of scanning is improved.
It is determined in step scanning, the environment as locating for us is all always to have electric wave signal, if our meter It measures prevention and control instrument in operation, cannot recognize that the control signal and environmental disturbances of cribber's remote controler, then this metering prevention and control Instrument can not reach preferable control effect.Therefore, in the present solution, joined environment-identification interference function, this Function needs to be manually entered unlike existing metering prevention and control instrument, but by comparison, search out the signal of environmental disturbances Frequency avoids this frequency, on the one hand reduces the workload of scanning when FM reception module receives.On the other hand, even if Some cribbers use this frequency, and emitting radio waves signal is practised fraud, but due to the presence of environmental disturbances, cribber It is to be difficult to success of practising fraud.Therefore in scanning receiving step, also specifying signal strength will be more than threshold value, i.e., below this threshold value Electric wave signal intensity it is weak, transmitting remote signal is difficult.More than threshold value environmental disturbances signal (in later reception, will not It receives again, i.e. be equal to the integer frequency has a powerful transmitting module to the environmental disturbances signal, ceaselessly launches outward Interference signal), cheating signal can also be interfered by the environmental disturbances signal.
Interference preventing control step is after practising fraud signal identification out, and transmitting module transmitting is identical with cheating signal frequency Interference signal interferes cheating signal.
It interferes and determines step, be to determine that interference enters into force, data are not tampered in other words.Therefore, it uses multiple Processing module is looked into, under normal circumstances, the design of weighbridge is that there is no check modules, therefore as background technique is said Check module is to install additional in the later period.Cribber distorts data, is concentrated mainly between weight sensor and single-chip microcontroller, therefore Weight sensor is connect with single-chip microcontroller and check processing module by we respectively, thus there are two signal paths, in weight After the signal path of sensor and single-chip microcontroller is tampered, check processing module can be found in time, then carry out warning note.
The present invention is used to measure the Intelligent preventive control method of prevention and control, first is that the electric wave signal in target band width is separated into Multiple frequency ranges allow multiple FM reception modules to receive respectively, compared with a FM reception module is only arranged in the prior art, improve Scanning received speed;Second is that intelligence identifies environmental disturbances signal, and ignore the reception to environmental disturbances signal, drops Low sampled point, to achieve the purpose that improve sample rate;Fourth is that check processing module can determine that interference comes into force, prevent from counting According to being tampered.
Further, it scans in receiving step, sampling received sampled point is integer point value.Change a form of presentation, sampled point Although narrowly discontinuous, sampled point is continuous integer value.The letter in a wider frequency section can either be reached in this way It number receives, and also improves reception speed.I.e. in the identical situation of sampling number, received bin width meeting in this programme It is substantially better than the prior art.
Further, it is interfering between determining step and warning note step, is further including high voltage protection step, handled in check After module determines that weighing results are modified, the both ends of memory module, single-chip microcontroller and weight sensor are grounded respectively, are passed in weight Circuit between sensor and memory module, memory module and single-chip microcontroller carries out high voltage stimulus with piezoelectric ceramics.Piezoelectric ceramics is said More popular is exactly the electronic ignition device in electronic lighter, which can generate up to ten thousand volts of high pressure, but electric current It is small, it is substantially harmless to human body, in the present invention, this device is added, is because the receiver of existing cheating is mounted on mostly Between weight sensor and single-chip microcontroller, therefore after monitoring that data are tampered, start this device, reception device can be damaged In chip or capacitor etc., and due to being grounded, weight sensor, single-chip microcontroller and memory module will not all be damaged It is bad.
Further, in scanning receiving step, the electric wave signal in 100-1000MHz frequency bandwidth is separated into three letters Three FM reception modules corresponding with signal frequency range are arranged in number frequency range.By our experiment simulations and prototyping testing, we It was found that being divided into three frequency ranges, cost and scanning speed can be taken into account.
It further, automatically will be apart from current after the result in memory module is recorded in the storage cap more than memory module The information deletion of time at most.Memory module can be allowed to operate normally, and calling verification of data history after user is facilitated to claim Weight information.
Further, choose a central processing module, will processing module corresponding with each FM reception module respectively with Central processing module connection allows central processing module to connect display module, and display module, which is shown, is currently judged as environmental disturbances Signal frequency.A central processing module, which is arranged, can allow each FM reception module work more to be coordinated, and avoid the occurrence of Multiple FM reception modules require the interference signal of transmitting module transmitting different frequency the same simultaneously.
Further, in scanning determining step, long-standing judgment criteria is that at least three FM reception modules connect The period is received with the presence of the electric wave signal of the frequency, and in the presence of the electric wave signal, check processing module receives weight biography Sensor is consistent with the feedback data of single-chip microcontroller.Such judgment criteria can more accurately determine the electric wave signal of environmental disturbances Frequency.
