Technical Field
The utility model relates to a device for preventing to change instrument calibration value cheating.
Background
At present, in the field of building materials and related detection, measuring instruments based on devices such as computers and single-chip microcomputers are adopted, field measurement data signals output by sensors are collected and processed and displayed by computer software, and the method is a common implementation form of various measuring and testing instruments. The measurement of the specific detection value is based on the following principle: the sensor of the measuring instrument collects the physical quantity to be measured, then converts the physical quantity into an electric signal with corresponding proportion, and finally obtains a measured value by processing the electric signal by computer software and comparing the electric signal with a calibrated value. However, since the calibration value of the instrument is directly stored in the computer and the proportionality coefficient of the corresponding processing software is easily modified, the calibration value is tampered in actual use, so that the measured value is distorted.
SUMMERY OF THE UTILITY MODEL
In order to solve and exist at present in the detection area and falsify calibration value etc. to the measuring instrument and lead to the unsafe technical problem of measuring result, the utility model provides a can be better prevent that calibration value is falsified prevent to change device that instrument calibration value cheated.
In order to achieve the technical purpose, the technical proposal of the utility model is that,
the utility model provides a prevent to change device calibration value cheat, includes measuring instrument and data server, the measuring instrument pass through network communication and be connected to the data server, be equipped with sensor communication module on the sensor that is used for data acquisition on the measuring instrument, sensor communication module pass through network communication and be connected to the data server, directly send the data that the sensor was gathered to the data server.
The device for preventing the cheating of changing the calibration value of the instrument is characterized in that the sensor communication module directly sends data collected by the sensor to the data server when the measuring instrument is calibrated or measured.
The device for preventing cheating of changing the calibration value of the instrument is characterized in that the sensor communication module is a cellular network communication module, a WiFi module or a Bluetooth module.
A method for preventing cheating of instrument modification calibration values comprises the following steps:
firstly, calibrating a measuring instrument, and storing a calibration value;
step two, measuring based on the stored calibration value;
and step three, after the measurement is finished, the sensor on the measuring instrument directly sends the acquired measurement data to the data server through the independent communication module arranged on the sensor, meanwhile, the measuring instrument also sends the measurement data to the data server, the data server simultaneously compares the measurement data uploaded by the measuring instrument and the sensor, if the measurement data are consistent with the measurement data, the measurement data are recorded, and if the measurement data are not valid, the measurement is judged.
The method for preventing cheating of the calibration value of the instrument change comprises the following steps in the first step:
the sensor directly transmits the sensing data acquired during calibration to the data server through the independent communication module arranged on the sensor, the data server simultaneously compares the calibration data uploaded by the measuring instrument and the sensor, if the calibration data are consistent, the calibration data are recorded, and if the calibration data are not valid, the calibration is judged.
The method for preventing the cheating of the calibration value of the instrument is characterized in that when the sensor uploads the measurement data, the pre-stored specific information for identifying the sensor is transmitted to the data server at the same time.
The technical effect of the utility model lies in, through set up communication module alone on the sensor, can make the sensor bypass the measuring instrument and come direct demarcation or measured data to uploading to data server, data server is after the data that contrast measuring instrument and sensor uploaded, and the judgement that just can be accurate fast is measured and is whether accurate for even if the calibration value is tampered with, also can be found by data server end, very big improvement data detection's accuracy reliable, help the expansion of quality supervision work.
The present invention will be further explained with reference to the accompanying drawings.

Detailed Description
Referring to fig. 1, the present embodiment includes a measurement instrument and a data server, the measurement instrument is connected to the data server through network communication, a sensor communication module is disposed on a sensor used for collecting data on the measurement instrument, the sensor communication module is connected to the data server through network communication, and the data collected by the sensor is directly sent to the data server.
In order to realize the comprehensive monitoring of the measured data, the sensor communication module respectively and directly sends the data acquired by the sensor to the data server when the measuring instrument is calibrated or measures.
In order to realize remote communication of the sensor, the sensor communication module is a cellular network communication module, a WiFi module or a Bluetooth module.
The method implemented by the embodiment comprises the following steps:
firstly, calibrating a measuring instrument, and storing a calibration value;
step two, measuring based on the stored calibration value;
and step three, after the measurement is finished, the sensor on the measuring instrument directly sends the acquired measurement data to the data server through the independent communication module arranged on the sensor, meanwhile, the measuring instrument also sends the measurement data to the data server, the data server simultaneously compares the measurement data uploaded by the measuring instrument and the sensor, if the measurement data are consistent with the measurement data, the measurement data are recorded, and if the measurement data are not valid, the measurement is judged.
In order to simultaneously monitor the calibration data, in the first step, the method further comprises the following steps:
the sensor directly transmits the sensing data acquired during calibration to the data server through the independent communication module arranged on the sensor, the data server simultaneously compares the calibration data uploaded by the measuring instrument and the sensor, if the calibration data are consistent, the calibration data are recorded, and if the calibration data are not valid, the calibration is judged.
In order to identify the source of the sensor data, when the sensor uploads the measurement data, specific information for identifying the sensor itself, which is stored in advance, is transmitted to the data server at the same time. The specific information may be a number preset by the sensor, or may be encrypted specific information, so that the data server can compare the information sent by the sensor of which measuring instrument after receiving the information.
Meanwhile, when data comparison is carried out, data synchronization is convenient, data can be quickly searched, and a retrieval label is provided for later data retrieval. The measurement data sent by the sensor directly to the data server, and the measurement data sent by the measurement instrument to the data server, all include information for identifying the source of the data. The information for identifying the data source can be the serial number given for each measurement experiment in sequence, namely, during measurement, an independent number is given for each measurement, and the number and the measurement data are sent to the data server together, so that as long as the numbers of the measurement data sent respectively are the same, the same measurement is carried out at the same time, and the data can be used for comparison. Of course, according to the actual situation, the corresponding information may also be other information for identifying the corresponding measurement experiment. Meanwhile, the measurement data can also comprise time stamp information for identification.
