The utility model has the advantages that: when the equipment is in a maintenance state, the safety protection device can control the stating and stopping of the drive motor at any position without being fixed at certain position for operation, thereby the safety of maintenance personnel can be effectively guaranteed.
Description
Technical field
The utility model relates to a kind of wireless security protection system, in particular for the safety guard on the full-sized car production line based on wireless network.
Background technology
Development along with radio network technique, the attractive force of radio communication in Industry Control Application strengthens day by day, many advantages that it brought comprise: can realize installing faster, need not reconfigure and can carry out physical displacement, be mounted to instinct and economize on the use of funds greatly by eliminating cable and reduction, and avoided in most of environments of plant the trouble waters of line as the dragnet.
The scene of automobile industry can exist various kinds of equipment usually, and a lot of equipment can not stop line, but sometimes the staff for to plant maintenance and maintenance, the equipment of but having to brave dangers near moving.Under normal conditions, for maintenance staff's safety, can adopt emergency stop switch protected usually.When maintainer's access arrangement scope is worked, also need other personnel and manually control in the place's operation of installation switch, arrange that such switch can play considerable effect.
Yet for the equipment that much is embedded in the melt pit, such as the plate chain etc., a large amount of driving arrangements are in melt pit, and when the maintenance personal entered, the external staff can't observe the situation of periphery, can't bring reliable personal safety to guarantee to it thus.In order to satisfy, must adopt portable safety feature to control in the safeguard protection of observing under the unclear situation.
Summary of the invention
The purpose of this utility model is at above-mentioned existing problems; propose to make the maintenance personal equipment be carried out the safety guard based on wireless network of emergency stop fast and accurately under a kind of, state that plant equipment can't be shut down not good in the maintenance personal position.
According to the technical scheme that the utility model provides, safety return circuit and apparatus control system interconnect, and apparatus control system is connected with Radio Network System.
Described safety return circuit comprises emergency stop switch, safety relay, safety programmable logic controller (hereinafter to be referred as safety PLC).
Wherein emergency stop switch access security relay is handled passive again access security programmable logic controller (PLC) PLC through the protection of safety relay.
Described apparatus control system is according to the operation of the signal controlling plate chain drive motor of outside and stop, stopping as enabling signal, overload signal, emergency, thereby.
Described safety return circuit links to each other by the programmable logic controller (PLC) of Industrial Ethernet and apparatus control system, the safety signal that safety return circuit is received is issued apparatus control system, the operation that the programmable logic controller (PLC) of apparatus control system comes control program according to the instruction of setting in advance.
Described Radio Network System comprises the wireless receiver that is connected under the BUS bus, single only portable transmitter, is connected the I/O module under the BUS bus.
The I/O module of band BUS bus is reserved one or two urgency and is stopped input end and corresponding output terminal, connects wireless receiver on the BUS port, by this transmitter receipt from the signal on the mobile transmitter.
The utility model is for those main equipments, and personnel's observation is not that the application of very comprehensive occasion is extremely important.When being in maintenance state for equipment, the maintenance personal need not be fixed near the operator's console, can be at an arbitrary position the radio that sends of button by this safety system the dangerous moment that operates at is stopped, guaranteed personnel's safety.

Embodiment
The utility model is provided with apparatus control system, and as shown in Figure 1, programmable logic controller (PLC) is also connecting the I/O module, and the I/O module is also connecting operator panel buttons, all kinds of switching signal, and these signals are being indicated the state of line body at present as common input signal.Safety PLC is transferred to programmable logic controller (PLC) to safety signal by Industrial Ethernet; PLC is according to the difference of safety signal grade, and it is to be in different processing modes such as time-out, outage shutdown that common input signal is come the controlling and driving motor with safety signal by logical program.
The utility model is provided with safety protection loop, as shown in Figure 2, be connected the I/O module on the BUS bus, this module access security signal, as safety door switch, emergency stop switch, safety barrier switch etc., export the switching value signal then and give safety relay, safety relay is installed on all kinds of high-protection levels place; After safety relay receives all kinds of safety signals, export several groups of passive signals and give safety PLC, safety PLC is handled various types of signal again, sends to programmable logic controller (PLC) according to safety signal different brackets selectivity.
The novel wireless system for transmitting data that is provided with of this use, as shown in Figure 3, on the I/O module that is connected on the BUS bus, tell a BUS port, on this port, connect wireless receiver, have the urgency of permanent wiring to stop input end, stop input end, show output terminal and each two input/output terminal for the urgency with 2 passages of wireless reservation on the I/O module with the anxious discontinuance of 2 passages.Selector switch is set on wireless receiver, and when the equipment normal operating condition, the wireless network of wireless receiver is chosen as the pass; When choice of equipment is manual mode or service mode, simultaneously the wireless network of wireless receiver is chosen as out, this moment, maintainer's portability mobile wireless transmitter carried out field maintemance.
The utility model is provided with wireless system for transmitting data, and as shown in Figure 4, when the no line options switch of wireless receiver was chosen as out, also for opening, this moment, both sides can carry out wireless transmission in same mobile wireless transmitter switch selection.Need the line body to suspend as the maintainer, then press the pause button on the wireless launcher, programmable logic controller (PLC) receives this information and stops after line handles, by wireless send to suspend finish instruction, time-out pilot lamp on the mobile wireless transmitter lights simultaneously, and prompting the maintainer note; Need the line body promptly to stop as the maintainer equally, press the emergency stop push button on the mobile wireless transmitter, programmable logic controller (PLC) receives this information and stops after line handles, promptly stop to finish instruction by wireless sending, the pilot lamp that promptly stops on the mobile wireless transmitter lights simultaneously, and prompting the maintainer note.On the mobile wireless transmitter, also be provided with Battery Indicator Light in addition, can prevent hand-held mobile radio transmitter personnel operation overlong time, battery electric quantity is not enough can remind the maintainer to leave the hazardous location.The mobile wireless transmitter is reserved two input/output signals in addition, is reserved with the signal of equivalent amount equally on the I/O module, so that other functions of user's increase are required.
