Than above-mentioned prior art, the utlity model has following advantage.
The anti-cheating shielding of weighbridge metering of the present utility model device; adopt the large-scale screening frequencies scope of 260～800MHz; can realize the comprehensive shielding action to the cheating device, thereby weighbridge is played a very good protection, effectively avoid because measuring the inaccurate economic loss that causes.
Description of drawings
Fig. 1 is the structured flowchart of the anti-cheating shielding of weighbridge metering device among the utility model embodiment.
The realization of the utility model purpose, functional characteristics and advantage are described further with reference to accompanying drawing in connection with embodiment.
Embodiment
Describe the technical solution of the utility model in detail below with reference to drawings and the specific embodiments, so as clearer, understand invention essence of the present utility model intuitively.
Fig. 1 is the structured flowchart of the anti-cheating shielding of weighbridge metering device among the utility model embodiment.
With reference to shown in Figure 1, present embodiment provides the anti-cheating shielding of a kind of weighbridge metering device 100, this shielding device comprises frequency receiver module 1, frequency transmitter module 2, anti-remote control module 3 and alarm module 4, frequency receiver module 1 is connected with anti-remote control module 3, and anti-remote control module 3 is connected with frequency transmitter module 2.Wherein, frequency receiver module 1 receive frequency is the weighbridge remote signal of 260～800MHz, and this signal outputed in the anti-remote control module 3, after anti-remote control module 3 receives above-mentioned signal, produce the undesired signal identical with this signal frequency, and be input in the frequency transmitter module 2, outwards launch by this frequency transmitter module 2, make weighbridge avoid the practising fraud remote control of device, demonstrate real metering numerical value.
Particularly, alarm module 4 is connected with frequency receiver module 1, and when frequency receiver module 1 received above-mentioned weighbridge remote signal, alarm module 4 started, and sends alerting signal.
Find with contrast by analysis, the present many proportions of cheating device are that the electromagnetic wave of several frequencies commonly used such as 303MHz, 390MHz and 418MHz is as the weighbridge remote signal, therefore, present embodiment frequency receiver module 1, frequency transmitter module 2 and anti-remote control module 3 also can frequency of operation be set to 303MHz, 309MHz and these three kinds of frequencies of 418MHz, or be set to 303～418MHz, to mate most cheating device, can reduce production costs again simultaneously.
In addition, present embodiment also comprises time block 5, and this time block 5 is connected with alarm module 4, and the duration of the alerting signal that alarm module 4 is sent is set.This alerting signal can adopt siren and/or warning lamp, and time block 5 can be set the airing of views time of siren, also can set the scintillation time of warning lamp, and the concrete length of time can be come fixed as required.
Simultaneously, the anti-cheating shielding of weighbridge metering device 100 also comprises counting module 6, and this counting module 6 is connected with anti-remote control module 3, is used for the number of starts of 3 of anti-remote control moulds is carried out record.And the numerical value in the counting module 6 can not be subject to the impact of startup and shutdown, and the numerical value of counting module 6 also can not be removed.The fundamental purpose that present embodiment arranges this counting module 6 is, because the price of the anti-cheating shielding of weighbridge metering device 100 products is comparatively expensive, ordinary consumer is often not too urgent to the demand of product, therefore, dealer or commission merchant can sell to rent, product hired out to the consumer use, then collect usage charges and rent according to the numerical value of record in the counting module 6, so just satisfied widely consumer's consumption demand, promoted its consumption experience, be particularly suitable for the consumer of those short-terms or Interim use weighbridge metering, to save its spending.
For the ease of using, present embodiment is set up power module 7 in the anti-cheating shielding of weighbridge metering device inside, adopts the mode of outside plug-in to power.For example, this power module 7 can comprise the plug that is connected for vehicle power, or the plug that is connected with vehicle-mounted cigarette lighter etc., so that in automobile, use.Also can comprise the plug that is connected for household socket, with the grafting civil power, at this moment, power module 7 just is equivalent to a power supply adaptor, and civil power is converted to low-voltage DC, for inner each circuit and module for power supply, uses also more convenient.In other embodiment of the utility model, also can accumulator (not shown) be set in the anti-cheating shielding of weighbridge metering device inside, adopt this storage battery power supply, so that mobile the use can be installed in the automobile, the metering process of weighbridge is monitored, Prevent cheating device remote control weighbridge, distort the metering numerical value of weighbridge, avoid inaccurate because of the weighbridge metering, cause great economic loss to enterprise.
In sum; the anti-cheating shielding of weighbridge metering of the present utility model device; adopt the large-scale screening frequencies scope of 260～800MHz; can realize the comprehensive shielding action to the cheating device; thereby metering plays a very good protection to weighbridge; thoroughly avoid inaccurate because of the weighbridge metering, cause great economic loss to enterprise.
The above only is preferred embodiment of the present utility model; be not so limit its claim; every equivalent structure transformation that utilizes the utility model instructions and accompanying drawing content to do; directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
