Abstract
The utility model relates to inspection and calibration of a weighing apparatus, and especially relates to a weighing apparatus status detection apparatus. The weighing apparatus status detection apparatus comprises a sensor interface, an on-off interface, an I/O processing circuit, an amplification circuit, an A/D converter, a display interface, an output interface, an MCU (a single-chip microcomputer), a UPS and accessory equipment. The weighing apparatus status detection apparatus can realize overall detection of a mechanical weighing apparatus body status and electrical equipment and accessory equipment status, and can also select one part to install as needed, and perform fault self-diagnosis and fault early warning, prevent manual misjudgment, and help to improve efficiency of workers. During the use of the weighing apparatus status detection apparatus, only partial equipment needs to be added to a conventional weighing apparatus and no big changes to the weighing apparatus is needed, and therefore the weighing apparatus status detection apparatus has an advantage of low construction cost.
Description
technical field:
The utility model relates to check and the calibration of weighing apparatus, particularly relates to a kind of weighing apparatus condition checkout gear.
background technology:
CN202915999U discloses a kind of " dynamic electronic rail balance fault device for fast detecting ", and it is made up of weighing platform, sensor, terminal box, A/D converter, for the on-mechanical fault detect of track scale.
Track scale is except on-mechanical fault, and no matter that link generation deviation of the associated components of scale body, working environment, integrality and the operation process relevant with weighing process, all can affect the accuracy of weighing.How the auxiliary device of track scale itself and periphery is carried out to complete detection, make track scale field maintemance personnel grasp in time the running status of weighing apparatus comprehensively, and it is particularly important to make timely early warning for the data of collecting.
summary of the invention:
A kind of weighing apparatus condition checkout gear is made up of sensor interface, switching value interface, I/O treatment circuit, amplifying circuit, A/D conversion, LCD display interface, output interface and several parts of MCU single-chip microcomputer, UPS and auxiliary device; Sensor interface has two kinds, range sensor and induction pick-up interface, is connected respectively with amplifying circuit, and amplifying circuit is again via access MCU after A/D conversion; Switching value input and switching value output are connected to MCU by I/0 circuit; LCD display interface also accesses MCU; UPS is connected into MCU by RS232 interface; Auxiliary device is connected into MCU by RS232 interface and RJ45 network interface; MCU connects network interface output, serial ports output and miscellaneous equipment intercommunication data.
Range sensor is used for being connected different classes of detecting sensor with induction pick-up interface; Range sensor interface is for connecting rail distance, rail gap, spacing equidistant measurement class sensor; Induction pick-up interface is used for connecting the sensor such as water level, sensor angle; This two classes sensor is for detecting in real time scale body outdoor machinery state and electric equipment.The sensor signal that is connected into equipment is transferred to device core device MCU in spi bus mode after amplifying circuit and A/D conversion; Switching value input is for the switching value of collection site auxiliary device used, and output is used for controlling field apparatus, and switching value input and output signal is input to I/0 processing of circuit, and signal after treatment is transferred to device core device MCU in spi bus mode; MCU reads UPS state by RS232 interface and detects city's electricity condition; The internal work state that main control MCU reads corresponding auxiliary device by RS232 interface and RJ45 network interface is realized auxiliary device and is detected, and it does not need extra hardware supported, integrated relevant function in auxiliary device.MCU carries out collection, analysis, the storage of late time data; LCD is the man-machine interface of operating equipment, for the information of collecting is presented in the understandable mode of user; Network interface output, serial ports output are used for the device intercommunicating data with other, facilitate equipment to be connected into detection or control kind equipment that user wishes.
Owing to adopting technique scheme, the major part of the utility model to weighing apparatus: the running status of mechanical scale body, electric equipment and auxiliary device state all can detect; And can select, to wherein partly installing, to reach the object that only certain equipment component to weighing apparatus detects.Fault self-diagnosis, fault are reported to the police in advance, the weighing apparatus that will go wrong is provided to prompting, maintainer just can control the status information of all weighing apparatus in inspection center, regularly patrol without every weighing apparatus again, avoid artificial erroneous judgement, improve staff's efficiency, reduced the personnel cost of enterprise.When use, on existing weighing apparatus basis, increase part part equipment, not needing has large change to weighing apparatus, possesses the advantage that construction cost is low.
accompanying drawing explanation:
Fig. 1 is structured flowchart of the present utility model.
Embodiment:
A kind of weighing apparatus condition checkout gear is made up of range sensor and induction pick-up interface, switching value output and input interface, I/O treatment circuit, amplifying circuit, A/D conversion, LCD display interface, output interface and several parts of MCU single-chip microcomputer, UPS and auxiliary device.
Range sensor is used for being connected different classes of detecting sensor with induction pick-up interface; Use at weighing-rail and down-lead rail rail gap that No. 4 range sensors detect, the weighing-rail gauge of table top uses that No. 2 range sensors detect, scale body deflection uses that No. 4 range sensors detect, the verticality of sensor is used that No. 4 angular transducers detect, water level uses that 1 road level sensor detects, transition detects and uses No. 4 range sensors to detect under scale body; Read that UPS state-detection city electricity condition, indoor temperature and humidity 1 road Temperature Humidity Sensor detect, indoor smog 1 road smoke transducer detects, come antitheft with 1 passerby's body induction sensor by RS232 interface.Main control MCU reads the internal work state of corresponding auxiliary device by RS232 interface and RJ45 network interface, as: weighing instrument state, license number meter status, video equipment state, network state, humiture etc. realize auxiliary device and detect, it does not need extra hardware supported, integrated relevant function in auxiliary device.
The sensor signal that is connected into equipment is transferred to device core device MCU in spi bus mode after amplifying circuit and A/D conversion; Switching value input and output signal is input to I/0 processing of circuit, and signal after treatment is transferred to device core device MCU in spi bus mode; MCU carries out collection, analysis, the storage of late time data; LCD is the man-machine interface of operating equipment, for the information of collecting is presented in the understandable mode of user; Network interface output, serial ports output are used for the device intercommunicating data with other, facilitate equipment to be connected into detection or control kind equipment that user wishes.
