Embodiment Construction

[0028] The present invention will be described in detail in conjunction with accompanying drawing now. This figure is a simplified schematic diagram only illustrating the basic structure of the present invention in a schematic manner, so it only shows the components relevant to the present invention.

[0029] Such as figure 1 As shown, a data processing method of blast furnace coal injection rate of the present invention includes the following steps: determine the sampling time t and the amount of sampled data N, collect the amount X of pulverized coal sprayed from the nozzle every time interval t and collect the sampled data Store it, when the amount of stored data reaches N, determine the maximum and minimum values ​​of the N data, then remove the maximum and minimum values, and calculate the average of the remaining N-2 data, as the N data exact value.

[0030] Further, including callable program blocks based on Phoenix programming software PCWork1.86 version, this progra...

Abstract

The invention provides a blast furnace coal injection rate data processing method. The method comprises the following steps of: 1, determining sampling time t and sampling data volume N, collecting the amount X of pulverized coal sprayed from a nozzle at an interval of t time, storing sampling data, determining a maximum value and a minimum value in N pieces of data when the stored data amount reaches N, removing the maximum value and the minimum value, and solving an average value of the remaining N-2 pieces of data to serve as an accurate value of the N pieces of data. Interference and distortion are reduced, and the action accuracy of the actuating mechanism is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data processing method for blast furnace coal injection rate. Background technique [0002] In engineering projects, it is often necessary to collect a large amount of on-site data, which are used to judge equipment status, on-site conditions, participate in chain control, and danger alarms. These data come from the on-site transmitter, which collects actual pressure, temperature, flow, concentration and other signals, converts them into 4 to 20mA or 0 to 10V electrical signals through the internal circuit, and finally transmits them to the PLC through the cable. Due to the large number of lines in the engineering site, this low-voltage and low-current signal will be interfered and distorted. For logic control, the distorted signal will cause the actuator to malfunction. So it is necessary to process the collected signal. [0003] When the on-site electrical signal is...
