Native machine verification standard device of multiple taximeters based on embedding type technology and verification method

Abstract

The invention discloses a native machine verification standard device of multiple taximeters based on the embedding type technology and a verification method. By use of the embedding type technology, the excellent performance of the PLC and a human-machine interaction interface, the native machine verification device is quite convenient to operate. Each host is capable of independently working and drives four stepping motors, so each host is enabled to finish the native machine verification of 1-4 taximeters. Meanwhile, each host can be used as an auxiliary machine to be connected with another host through the network, so verification of multiple taximeters is achieved. Global control through the same host when multiple auxiliary machines are linked through the network is achieved and acquisition data of other auxiliary machines can be collected, checked and printed. The verification items are clear and each verification item has an independent operation interface, so when a certain item needs to be detected, a corresponding module is called through a touch screen, parameter setting is performed and mis-operation is avoided. According to the invention, by use of the human-machine interaction interface, detection results are automatically calculated and errors caused by manual calculation are reduced.

Description

technical field [0001] The invention relates to a multi-way taxi meter local verification standard device and a verification method based on embedded technology, which belongs to the technical field of measurement and is applied to the measurement verification industry, in particular to a detection device for taxi meter verification. Background technique [0002] The taxi meter is a special measuring instrument installed on the taxi to realize the trade settlement between the passenger and the operator or driver in the form of metering and timing. Newly-manufactured or repaired taximeters whose software and hardware have been changed must undergo local verification before loading into the vehicle; after the taximeters that pass the local verification are installed on the car, they must be regularly checked for use error together with the car to ensure The usage error of the meter in the usage environment is within the range stipulated by the state. Therefore, the verificati...

Problems solved by technology

[0006] The present invention aims at the technical problem that the traditional taximeter’s local verification standard device only matches one stepping motor, and can only verify a single parameter of one taximeter at a time, and invents a multi-way taxi pricing based on embedded technology The standard device for the verification of the meter is used to achieve the purpose of independently verifying multiple fare meters at the same time
