Abstract
The utility model belonging to the information processing equipment field, particularly relates to a gas meter calibrator. The hand-hold meter calibrator comprises a body. The body is provided with a power supply and a CPU controller. The CPU controller is respectively connected with a memory, a display module, an input module for inputting the meter calibration information, and a meter calibration module for calibrating the gas meter. The CPU controller is further connected with an infrared transceiver module. The hand-hold meter calibrator can send the infrared meter calibration signal through the infrared transceiver module, thus completing the calibration of the gas meter, has the advantages of small size and portable characteristic, and is very suitable for the scattered meter calibration.
Description
Technical field
The utility model belongs to the messaging device field, particularly the gas meter, flow meter tester.
Background technology
Gas meter, flow meter uses after a period of time because the influence of environment for use, the inaccurate phenomenon of table may appear walking, at this time need to carry out calibration through calibration software, and common calibration software all is mounted on desktop computer or the notebook computer, by sending the calibration signal to the calibration module on the gas meter, flow meter, by the calibration module gas flow is calibrated and to make the degree of accuracy of gas flow higher, yet the volume of computer has seriously restricted property easy to carry, the dirigibility of calibration and efficient has been produced seriously influence.
Summary of the invention
The utility model at the problems referred to above provide a kind of volume little, be convenient for carrying, noiselessness, easy-operating gas meter, flow meter calibration equipment.
The technical solution of the utility model is: a kind of hand-held calibration machine, comprise body, be provided with power supply, cpu controller in the described body, cpu controller is connected with storer, display module respectively, be used to the calibration module importing the load module of calibration information and be used to proofread and correct gas meter, flow meter, and described cpu controller also is connected with infrared transceiver module.
As preferably, what described display module adopted is LCDs.
The utility model sends infrared calibration signal by the independent hand-held calibration equipment of design by infrared transceiver module, and gas meter, flow meter is finished calibration work, has the advantages that volume is little, be convenient for carrying, and is fit to very much the calibration operation that disperses.
Description of drawings
Fig. 1 is a theory diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of hand-held calibration machine, comprise body, be provided with power supply, cpu controller in the described body, cpu controller is connected with storer, display module respectively, is used to proofread and correct the calibration module of gas meter, flow meter and the load module that is used to import calibration information, and described cpu controller also is connected with infrared transceiver module.What described display module adopted is LCDs.
Hand-held calibration machine is when carrying out calibration to gas meter, flow meter, the operator at first reads the essential information of gas meter, flow meter by the load module operation interface, as flow velocity of gas meter, flow meter etc., display module demonstrates the information of gas meter, flow meter, the calibration module is transferred to cpu controller according to the requirement that the information of gas meter, flow meter obtains calibration, cpu controller control infrared transceiver module sends infrared calibration signal to gas meter, flow meter, the infrared receiving device that receives infrared calibration signal is arranged on the gas meter, flow meter, gas meter, flow meter is proofreaied and correct gas meter, flow meter by means for correcting according to the infrared calibration signal that receives.The method of proofreading and correct is that updating formula is Q
t=KQ+B, wherein Q
tFor proofreading and correct later flow, the theoretical delivery value of Q for calculating according to formula, K, B are correction parameter, K, B value determine can theoretical value and actual value by many groups gas meter, flow meter of obtaining after, the value of correction parameter K, a B by definite the bests such as least square method or curve fitting methods again.
Claims (2)
1. hand-held calibration machine, comprise body, be provided with power supply, cpu controller in the described body, it is characterized in that, described cpu controller is connected with storer, display module respectively, is used to proofread and correct the calibration module of gas meter, flow meter and the load module that is used to import calibration information, and described cpu controller also is connected with infrared transceiver module.
