Embodiment 1

[0039] Such as figure 1 As shown, an Internet of Things system includes on-site collection, network transmission, and remote monitoring platform; the on-site collection transmits data to the monitoring platform through a telecommunication private network to realize data interaction. On-site acquisition module: Use on-site sensors to measure and monitor scene data information, and output the results. For floating-point data information, the output value OUT is calculated by the following data proportional conversion formula: OUT=[((FLOAT(IN)-IN_LO) / (IN_HI-IN_LO))*(OUT_HI-OUT_LO)]+OUT_LO;

[0040] Among them, OUT is the conversion output result, IN is the conversion input object, IN_HI is the high limit of the conversion object, IN_LO is the low limit of the conversion object, OUT_HI is the high limit of the conversion result, and OUT_LO is the low limit of the conversion result.

[0041] Such as figure 2 As shown, the network transmission module: utilizes the network transm...

Embodiment 2

[0047] Such as image 3 As shown, the data conversion method is calculated by the following formula:

[0048] OUT=[((FLOAT(IN)-IN_LO) / (IN_HI-IN_LO))*(OUT_HI-OUT_LO)]+OUT_LO

[0049] Among them, OUT is the conversion output result, IN is the conversion input object, IN_HI is the high limit of the conversion object, IN_LO is the low limit of the conversion object, OUT_HI is the high limit of the conversion result, and OUT_LO is the low limit of the conversion result.

Abstract

The invention discloses an automatic process equipment data conversion and instruction remote issuing method, and relates to the technical field of Internet of Things communication application. The system comprises instrument equipment, an industrial photoelectric switch, a PLC (Programmable Logic Controller), a KepServer, a data acquisition program and a monitoring platform, the automatic process equipment remote instruction issuing method comprises the following steps: acquiring an original data module; defining a variable address and a label; reading data from the PLC by using a KepServer, reading the data of the KepServer by using an acquisition program, and sending the data to a monitoring platform; and the monitoring platform issues a corresponding operation instruction and writes the instruction into the PLC, and the PLC writes the instruction into the field instrument equipment. The operation state and operation data change of the automatic process equipment are remotely monitored in the central control room, and parameter setting and state switching can be remotely performed on the automatic process equipment, so that dynamic configuration and centralized monitoring capabilities are provided for flexible configuration of instrument equipment, the operation cost of an enterprise is reduced, and the working efficiency of the enterprise is improved. And remote monitoring of the sub-control station is realized.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things communication applications, and in particular relates to a method for data conversion of automatic process equipment and remote delivery of instructions. Background technique [0002] With the construction of industrial Internet of Things equipment and facilities and the rapid development of Internet communication technology, involving sewage plant monitoring, pumping station monitoring, gate monitoring, urban drainage pipe network monitoring and other fields, the parameter setting and status control of automated process equipment based on the Internet of Things system It provides users with convenient, efficient and stable remote control of field equipment, and has been recognized by many companies. [0003] The automatic control system adopts a distributed distributed computer control system, which is composed of a central control room and various on-site control stations (sub-control...
