Description

Vehicular weighing digital measurer

Technical field:

The present invention relates to a kind of measurement instrument, especially relate to a kind of Vehicular weighing digital measurer.

Background technology:

At present, at home and abroad in the like product market, to the mensuration of weighing of all motor vehicles and the goods that loaded, mostly be the conventional metered dose mode that adopts all kinds of on-ground weighers or track weighing apparatus etc., the one, its error is bigger, degree of accuracy is lower, sensitivity is relatively poor, and its volume is extremely huge and heavy, production, installation and running cost height, the inconvenience care and maintenance, calibrating and repair cost height; The 2nd, most of on-ground weighers or track weighing apparatus all need to build the house and hide, it is installed in indoor use, construction cost is high, also motor vehicles and the goods that is loaded will be driven to transport to on-ground weigher or track weighing apparatus in addition gets on to be weighed and weighs, so not only taken a lot of work but also time-consuming, its weighing use cost is higher; The 3rd, inconvenient motor vehicle operator is driving to check the deadweight of grasping motor vehicles and the goods weight that is loaded in transit at any time, can not realize that the deadweight of motor vehicles and institute's lade weight are at the dynamic measurement of driving in transit; The 4th, because artificial the reequiping of some motor vehicles, the overload overrun condition has become a kind of extremely general phenomenon, cause the pernicious security incident of road to happen occasionally, the utmost point is not easy to highway administration and road supervision, and these all become the serious problems in the actual conditions.

Summary of the invention:

The objective of the invention is to overcome the deficiencies in the prior art, a kind of Vehicular weighing digital measurer is provided, this gauge is to adopt the stress change among four groups of bridge-type steel spring plates of the headstock below that is installed in motor vehicles respectively and vehicle body below to send the combined type weighing sensing device, realize the deadweight of motor vehicles and the static weighing or the dynamic measurement of institute's lade weight with this, and send and the demonstration of static or dynamic control demonstration electronic-circuit device realization numeral by micro computer information acquisition change.It can not only carry out static state or dynamic accurate measurement to deadweight and institute's lade weight of various motor vehicles, but also has high reliability, stability and security.

The technical scheme that reaches the object of the invention is: below the headstock of motor vehicles with vehicle body below four groups of bridge-type steel spring plates among fixedly connected a kind of stress respectively and become and send the combined type weighing sensing device, the deadweight of its four groups of bridge-type steel spring plate tops and the total weight of institute's lade can both pressure-bearing be sent on the combined type weighing sensing device in these four stress changes, and the deadweight of this device top is demarcated the back meter with its below to the total weight of four groups of tires allowance for bark as the deadweight of whole motor vehicles, closely paste one group respectively at these four device inner surfaces and can produce the metal strain plate sensing material that effect is sent in the stress change, simultaneously in these four devices, be respectively equipped with the one group of electronic circuit that can export analog electrical signal, respectively just with the input of these the four groups electronic circuits that can export analog electrical signal by electric wire, the output of negative connector and the metal strain plate sensing material of wherein closely pasting just, negative connector is connected; Fixedly connected micro computer information acquisition change is sent and static or dynamic control demonstration electronic-circuit device on the panel board of vehicle driving chamber, and by high shielded cable the analog electrical signal of its device is imported positive and negative level joint and send positive and negative grade of joint of the analog electrical signal that electronic circuit produced output of combined type weighing sensing device to be connected with four stress changes respectively; The micro computer information acquisition become give and static or dynamically control show that the positive and negative level of the power supply input joint of electronic-circuit device is connected with the positive and negative level of vehicular power-bottle power supply output joint by electric wire, and set up a power regulator in positive and negative grade of joint of power supply input of this device.

The present invention has following principle of work: the present invention adopts stress to become to send the static of deadweight that combined type weighing and sensing technology comes the measuring machine motor vehicle and institute's lade weight or measures situation of change dynamically, and by the micro computer information acquisition become give and static or dynamically control show that electronic-circuit device becomes stress and send the analog electrical signal of the combined type STRESS VARIATION situation that weighing sensing device is produced to gather amplification, receive and handle, analog to digital conversion becomes to be sent, the control of transfiniting is reported to the police, static state or dynamic digital show automatically fast, stress being become the total weight demarcation back meter of below to the four group tire that send the combined type weighing sensing device as the deadweight of whole motor vehicles allowances for bark again, what this technology was mainly leaned on has adopted a kind of section to emulate the advanced, rationally the stress that is suitable for becomes the combined type weighing and sensing mode of sending, and is used as the static of the deadweight of motor vehicles and institute's lade weight or measures the information sensing of situation of change dynamically with this.On the one hand, when stress that this technical approach adopted become send the combined type weighing sensing device at motor vehicles deadweight and the pressure-bearing effect of institute's lade weight under when producing deformation, and physical change also takes place in the metal strain plate sensing material that closely sticks in this device thereupon, be transformed into a kind of analog electrical signal, again stress become the total weight demarcation back meter of below to the four group tire that send the combined type weighing sensing device as the deadweight of whole motor vehicles and allowance for bark.On the other hand, utilize a micro computer information acquisition being fixedly connected on the panel board of vehicle driving chamber to become again to give and static or dynamically control show the electronic-circuit device counter stress become send the combined type analog electrical signal that weighing sensing device is generated gather amplifications, receive handle, analog to digital conversion becomes transfinite control warning, static state or the dynamic digital of sending, overload and shows fast automatically, even if can obtain the deadweight of motor vehicles very accurately and the static weighing or the dynamic measurement of institute's lade weight fast.

The present invention has following beneficial effect: from above-mentioned situation as can be known, the objective of the invention is to realize, it can send the deadweight of the next accurate measuring machine motor vehicle of this technical approach of combined type weighing sensing device and the static or dynamic number change situation of institute's lade weight with the stress change, realization is carried out quick digital display metering to its number change situation, it is really to have embodied high-performance, pinpoint accuracy, high sensitivity, high reliability, high stability, high security, error is little, response speed is fast, vibration resistance is strong, variation of temperature resistance humidity and adaptive capacity to environment are strong, zero point drift is little, energy consumption is low, volume is little, in light weight, processing and use cost are low, swift to operate, easy to use, easy care, beneficial effect and characteristics such as maintenance and maintenance.
