Abstract
The utility model discloses an air compressor remote control device which comprises an upper computer and a programmable logic controller (PLC) control system. The upper computer is in communication connection with the PLC control system. A digital output module of the PLC control system outputs signals to an intermediate relay. Normally-open contacts of the intermediate relay are in series connection in an air compressor starting and stopping circuit so that a compression engine of an air compressor can run in a reliable working constant-voltage state. As a result, labor intensity of operators can be mitigated, the operators can also stop the compression engine of the air compressor rapidly when equipment is in emergency, and therefore safety of the operators and safety of the equipment are guaranteed, and a large number of potential safety hazards are avoided.
Description
Technical field
The utility model relates to the air compressor field, relates in particular to a kind of air compressor remote control.
Background technique
At present, the kind of air compressor has a lot, but its air feed control mode nearly all is that employing adds, the Unloading Control mode.Adopted this control mode as U.S.'s longevity power helical-lobe compressor, but U.S. Shou Li company is not open to the user to communication protocol, so can't realize the remote control function of longevity power air compressor all the time, the control upper-position unit is controlled the startup of air compressor and is stopped in promptly can't realizing utilizing.If buy communication protocol to U.S. Shou Li company, need 200,000 yuan, and need to change 4 of control panels of computer (being worth 80,000 yuan), so not only this enterprise has increased added burden, also is restricted.
The start-up control mode of the fixed screw air compressor of U.S.'s longevity power is local panel manual operation control mode, since longevity power air compressor do not realize the telecontrol air compressor start hold function, 4 air compressors of control operating room distance are about 12 meters far away in adding, need to start at every turn when stopping air compressor, operator will go to 12 meters and far remove the switch air compressor, bring inconvenience to operator like this, not only increase labor intensity of operating personnel, but also be traditional starting-up method, scientific and technological content is not high, particularly in case of emergency, must there be more potential safety hazards in operator's shutdown of can not reaching the spot rapidly in this process.
The model utility content
The purpose of this utility model provides a kind of air compressor remote control, can conveniently carry out telecontrol to air compressor.
The utility model adopts following technical proposals: a kind of air compressor remote control, comprise upper-position unit, PLC control system, described upper-position unit and PLC control system communicate to connect, the digital output module of described PLC control system outputs signal to auxiliary reclay, and the normally opened contact of auxiliary reclay is connected in the air compressor start and stop circuit.
The utility model can be realized the remote activation of air compressor/stop control, make the air compressor compressor operating under the pressure constant state of working reliably, so not only alleviate labor intensity of operating personnel, and equipment in case of emergency, operator can shut down rapidly, thereby guaranteed the safety of personnel and equipment, avoided many potential safety hazards; This device is transformed on original control technique basis, and reforming cost is low, and control is reliable, and is remarkably productive.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
As shown in Figure 1, a kind of air compressor remote control of the utility model, comprise upper-position unit, PLC control system, described upper-position unit and PLC control system communicate to connect, the digital output module of described PLC control system outputs signal to auxiliary reclay, and the normally opened contact of auxiliary reclay is connected in the air compressor start and stop circuit.Upper-position unit utilizes the WICC monitoring software to send instruction for the PLC control system, by numeral input output module SM323, the signal of output is controlled auxiliary reclay, make auxiliary reclay coil KA adhesive, utilize its normally opened contact to connect the startup of air compressor/stop control end (35,36), give pulse signal of air compressor start-up control circuit, by 35, the connection of 36 ends or disconnection, realized the remote activation of air compressor/stop control procedure, make the air compressor compressor operating under reliable work pressure constant state by digital quantity control realize air compressor remote activation stop air compressor, so not only alleviate labor intensity of operating personnel, and equipment in case of emergency, operator can shut down rapidly, thereby have guaranteed the safety of personnel and equipment, have avoided many potential safety hazards.
