Abstract
The invention discloses a signal transmission method and a device for a sensor and a master control PLC (programmable logic controller). The method comprises the steps that a wireless node adapter is arranged on the sensor, so that a data signal of the sensor is sent by the wireless node adapter; a wireless gateway is arranged on the master control PLC; and the wireless gateway receives data sent by the wireless node adapter and then sends the received data to the master control PLC through the wireless gateway, so that the problem of poor contact of a data transmission line between the sensor and the master control PLC is solved. According to the method and the device, the wireless node adapter and the wireless gateway are arranged correspondingly between the sensor and the master control PLC, so that data transmission is realized through a wireless transmission mode between the sensor and the master control PLC, and the defects arising from a wired connection mode, such as production accidents due to cable core fracture or connection point looseness are overcome. The method and the device are simple in structure, convenient to use and good in using effect.
Description
Technical field
The present invention relates to a kind of sensing system, method for transmitting signals and the device of especially a kind of sensor and main control PLC.
Background technology
At present, be installed in all kinds of sensing One's name is legions on the equipment such as carbon block stacking crown block, the multi-functional unit of roasting, and all the sensors all is the main control PLC of signal input carbon block stacking crown block by cable.But, because the various kinds of sensors that is contained on these equipment all is installed on the parts that need to move usually, and long-term reciprocal movement and the vibration of these parts, therefore, the long-time use of process will cause cable core to fracture or wiring point becomes flexible, make main control PLC not receive normal signal, thereby cause industrial accident to take place.
Summary of the invention
Technical matters to be solved by this invention is, method for transmitting signals and the device of a kind of sensor and main control PLC is provided, it can avoid stube cable core between main control PLC and the sensor to fracture or wiring point loosening, to overcome the prior art deficiency.
Technical scheme of the present invention: the method for transmitting signals of sensor and main control PLC, at sensor the radio node adapter is set, the data-signal of sensor is sent by the radio node adapter, and in main control PLC radio network gateway is set, radio network gateway receives the data that the radio node adapter sends, by radio network gateway the data that receive are sent in the main control PLC again, thereby avoid the problem of the data line loose contact between sensor and the main control PLC.
The signal transmitting apparatus of sensor and main control PLC, it comprises main control PLC, sensor, be connected with radio network gateway in main control PLC, be connected with the radio node adapter at sensor, the radio node adapter is connected with radio network gateway, is wireless connections between radio node adapter and the radio network gateway.
Compared with prior art, owing to adopt technique scheme, the present invention arranges corresponding radio node adapter and radio network gateway with reaching between the main control PLC adopting at sensor, make between sensor and the main control PLC and realize data transmission by Wireless transmission mode, avoided adopting wired mode of connection to bring drawback: fracture or wiring point is loosening and cause industrial accident to take place as cable core.Method of the present invention is simple, and the device that adopts is made easily, and is easy to use, and result of use is good.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Embodiments of the invention: the method for transmitting signals of sensor and main control PLC, at sensor the radio node adapter is set, the data-signal of sensor is sent by the radio node adapter, and in main control PLC radio network gateway is set, radio network gateway receives the data that the radio node adapter sends, by radio network gateway the data that receive are sent in the main control PLC again, thereby avoid the problem of the data line loose contact between sensor and the main control PLC.
The structure of the signal transmitting apparatus of sensor and main control PLC as shown in Figure 1, a radio network gateway 2(of installation radio network gateway 2 can adopt radio transmission apparatus such as commercially available wireless router or wireless exchange board near main control PLC 1), radio network gateway 2 and the telecommunication cable of main control PLC 1 by one section very short are coupled together, a radio node adapter 3 is installed near each sensor 4, radio node adapter 3 is coupled together by very short cable, adopt wireless connections between radio node adapter 3 and the radio network gateway 2, the communications protocol of supporting between radio node adapter 3 and the radio network gateway 2 has RS-485 Modbus RTU, Modbus TCP or Ethernet IP.
In use, what sensor 4 will be gathered is transferred to radio node adapter 3 to data line, radio node adapter 3 radio node adapters 3 are by wireless network and radio network gateway 2 communications, radio network gateway 2 is the sensor signal that receives input main control PLC 1, and the transmission speed of all pilot signals satisfies the carbon block stacking crown block fully or burns the action response rate request of equipment such as multi-functional unit.
