The system specifically comprises a workshop section monitoring module 1 and a processing control system 2.
The section monitoring module 1 comprises parameter detection units arranged on each operation section of a gypsum board production line and is used for detecting the operation parameter states of gypsum board raw material conveying and formed gypsum board conveying.
The parameter detection unit is specifically a detection sensor 101 arranged on each operation section, and a transmission module 102 for converting the detection sensor 101 into a coupling switching value signal, the transmission module 102 transmits data to an input module 201, and the detection sensor 101 mainly comprises a photoelectric switch, a temperature sensor and a pressure sensor.

A current type transmitter is generally used for converting a physical quantity into a current output of 4-20 mA, so that the transmitter is equivalent to a special load in a circuit, and the special characteristic is that the power consumption current of the transmitter is changed between 4-20 mA according to the output change of a sensor.

The executive component 4 is motor equipment or a lighting lamp of each section, the alternating current contactor is closed, all the equipment is started, and otherwise, the equipment is stopped. The actuator 4 may be provided in plural numbers and distributed in each control section of the production line.
Example 2
As shown in FIG. 3, in order to avoid the idle running condition when the feeding on the conveyer belt is not in time on the gypsum board production line, the invention provides a power-saving control method of the gypsum board production line.
The method specifically comprises the following steps:
firstly, setting control detection points at each operation working section of a gypsum board production flow, distinguishing monitoring parameter types of the control detection points according to the production content of each operation working section, and collecting parameter operation information of the monitoring working sections in real time.
As shown in fig. 4, the gypsum board production process includes an illumination system disposed at different sections of the whole production line, a raw material section for conveying gypsum raw materials, a thermal section for conveying gypsum slurry to prepare heat source coal material, a first control section for extrusion molding, conveying and transferring gypsum slurry, a second control section for conveying formed gypsum boards to a dryer, a drying section for drying and dehydrating the extruded gypsum boards, and a third control section for conveying and stacking the dried gypsum boards.
Because the raw material working section and the heating power working section mainly control the proportioning component of the gypsum slurry, the control detection points on the raw material working section and the heating power working section are specifically pressure sensors which are used for detecting the weight change of materials in the raw material working section and the heating power working section.
The first control working section, the second control working section and the third control working section are all used for continuously conveying and transferring the gypsum boards, so the control detection points on the first control working section, the second control working section and the third control working section are photoelectric switches used for detecting the setting conveying and drying conveying states of the gypsum boards, the transfer of the gypsum boards also needs to be completed in the drying process of the gypsum boards, and the control detection points in the drying machine are the photoelectric switches used for detecting the work of conveying roller ways in the drying machine.
The parameter operation information comprises timing information, idling information is screened from the parameter operation information, the operation duration of the idling information is counted according to the timing information corresponding to the acquired idling information each time, and the related workshop section is controlled to pause.
Therefore, according to the working content and the working form of each operation working section, the control detection point corresponding to each operation working section is set, a light intensity detector is installed in a production workshop to facilitate the control of the lighting system of the production workshop, when the production line stops, the brightness response of the lighting system is reduced, and meanwhile, when the light brightness changes, the brightness of the lighting system is also adjusted in a responding mode, so that the resource waste is reduced.
In order to avoid the overhigh or overlow temperature of the drying section, the drying section is provided with a temperature sensor for collecting the air temperature in the dryer, so that the drying temperature is kept stable on one hand, and the waste of electric energy is reduced on the other hand by controlling the temperature of the drying section in a frequency conversion mode.
And initializing all control detection points each time the gypsum board production line is operated.
And then, setting a parameter threshold value for normal operation of each working section, screening normal working information and idle information detected at a control detection point of each working section, and performing logic operation processing on the idle information according to the incidence relation among the working sections.
The step is mainly based on the comparison of real-time information acquired by controlling the detection points and a parameter threshold value, all detection information corresponds to normal working information of each operation working section and no-load idle running information, when a certain operation working section is found to have idle running, the working of the operation working section is immediately stopped, and simultaneously, the working sections related to the operation working section are also stopped according to the incidence relation, so that the electric quantity wasted by idle running of the current operation working section can be saved, the electric quantity wasted by other operation working sections can be saved, and the electric quantity saving efficiency of the electric quantity can be further improved.
Through practical application statistics, the unit power consumption of the product (full production calculation of 300 days in the whole year) of the gypsum board production line is reduced by about 25 percent, and compared with the method of only stopping power supply of the idle running section alone, the unit power consumption is further reduced by about 10 percent.
The division and calibration of the incidence relation among the multiple working sections provided by the embodiment is accurately defined as: the production flow of gypsum board is divided into a downstream section consisting of a drying section and a three-control section by taking the drying section as a boundary, and an upstream section consisting of a raw material section, a thermal section, a first-control section and a second-control section.
The upstream section and the downstream section form a whole gypsum board production line, the upstream section is mainly used for producing gypsum boards, the gypsum boards are transferred from the upstream section and enter the dryer to be intensively dried, and the downstream section continuously transfers and stacks the dried gypsum boards, so that when the upstream section idles at a certain moment, the dryer can still continuously perform drying operation, and when the upstream section idles in the gypsum board manufacturing and shaping process, the downstream section normally works.
When the downstream section is idle, meaning the gypsum board in the dryer is in the drying process, the relevant section of the upstream section is also suspended and stopped, so that the gypsum board is prevented from being continuously conveyed to the inside of the dryer, and the condition of accumulation at an inlet of the dryer is avoided.
And finally, controlling the start and stop of the plurality of working sections according to the duration of the idle information.
Therefore, in the two steps, the power-saving control is performed on the working sections of the gypsum board production line, the linkage relationship is established between different working sections instead of the single control according to the detection information of a certain working section, and when a certain source working section idles, other working sections related to the certain source working section are suspended, so that the power can be saved maximally.
The operation of establishing the linkage relationship of different sections specifically comprises the following steps:
and performing depth traversal on the sections of the upstream section, respectively determining the linkage relation between any section and the rest sections in the upstream section, and determining the influence conditions between the sections with the linkage reaction relation in the upstream section.
Determining the linkage relation between the drying workshop section and the three control workshop section in the downstream section, and determining the influence conditions of the drying workshop section and the three control workshop section.
Because the upstream section and the downstream section use the drying section as a boundary point, the linkage relationship between the operating sections of the upstream section and the downstream section is independently obtained when the linkage relationship is analyzed.
For example, for the downstream section composed of the raw material section, the thermal section, the first control section and the second control section, when the raw material section runs idle, which means that the raw material is not supplied enough, the first control section, the second control section and the thermal section can be suspended until the raw material section releases the idle state, and the first control section, the second control section and the thermal section can not continue to work.
When the first control working section has idle running, the gypsum board shaping work at the moment is slow, and the first control working section and the second control working section can pause.
When the drying section in the downstream section is idle, meaning that the gypsum board is being dried at this time, no material is output, the drying section and the three-control section may be suspended.
In general, the master control source points of the downstream section are found out respectively, any one operating section is taken as a node, other operating sections are traversed, the linkage relation is determined, and a control system is established, so that the power saving control is facilitated.
It should be noted that the power saving control system of the present embodiment can also be applied to the failure processing of the gypsum board production line, in the failure processing system of the gypsum board production line, the relationship between the upstream section and the downstream section still exists, and it can be stated that the operating state of the downstream section is a sufficient unnecessary condition of the operating state of the upstream section, when a problem occurs in the drying stage, the upstream section needs to stop production, and when a problem occurs in the production stage, the drying stage can continue the drying and stacking processing of the remaining gypsum boards.
Meanwhile, the illumination brightness of the existing production workshop illumination system is mostly related to the light intensity, the embodiment associates the working states of the upstream section and the downstream section with the light scheduling of the illumination system for better and more meticulous control of the light scheduling of the illumination system, when the upstream section or the downstream section is in the working state, the production workshop of the illumination system is regulated and controlled to be high illumination, when the upstream section or the downstream section is in an idle running state, the production workshop of the illumination system is regulated and controlled to be low illumination, and on the premise of not interfering normal production, the illumination brightness consumption is reduced as far as possible.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
