Abstract
The utility model discloses an alarm control system based on PLC, comprising an input module, a display module, a PLC control module, a converter, a RS485 communication bus and a signal acquisition module, wherein the input module and the display module are connected with the PLC control module, the PLC control module, the converter, the RS485 communication bus and the signal acquisition module are connected, the converter is an RS232-to-RS485 converter, and the display module is an LCD display. The alarm control system is simple in structure, low in production cost, strong in system stability, long in service lifetime and easy for maintenance.
Description
Technical field
The utility model relates to a kind of warning system, relates in particular to a kind of alarm control system based on PLC.
Background technology
The flow process that existing panalarm uses generally is to input first instruction, instruction links to each other with common status bus with bus interface circuit by the bus demodulator circuit, common status bus is connected with detector again, and detector returns to control center with required data, then by display information is shown.The designed system hardware configuration is relatively complicated in this way, stability is poor, function ratio is more single, the serviceable life of system is short, if want equipment is upgraded, just need to increase again detector and corresponding hardware device, also just increase upgrade cost, caused the difficulty of later maintenance.
Summary of the invention
In order to overcome the deficiencies in the prior art, of the present utility model provide a kind of simple in structure, production cost is low, system stability is strong, long service life, the alarm control system based on PLC that is easy to safeguard.
By the following technical solutions of the present utility model:
A kind of alarm control system based on PLC, formed by load module, display module, PLC control module, converter, RS485 communication bus, signal acquisition module, described load module, display module link to each other with the PLC control module, and PLC control module, converter, RS485 communication bus, signal acquisition module link to each other.
Described converter is that RS232 turns the RS485 converter.
As preferably, described display module is LCD display.
The beneficial effects of the utility model: the utility model is simple in structure, production cost is low, system stability is strong, long service life, is easy to safeguard.
Description of drawings
Fig. 1 is system chart of the present utility model.
Embodiment
A kind of alarm control system based on PLC as shown in Figure 1, formed by load module 1, display module 2, PLC control module 3, converter 4, RS485 communication bus 5, signal acquisition module 6, described load module 1, display module 2 link to each other with PLC control module 3, and PLC control module 3, converter 4, RS485 communication bus 5, signal acquisition module 6 link to each other.
Signal acquisition module 6 converts the signal that collects to the RS485 communication signal by RS485 communication bus 5, converter 4 converts the RS485 communication signal to the RS232 communication signal, and the RS232 communication signal is transferred to PLC control module 3, show at display module 2 at last.
The user sends instruction by load module 1, PLC control module 3 receives the RS232 communication signal and sends to converter 4, converter 4 converts the RS232 communication signal RS485 communication signal to and sends to RS485 communication bus 5, RS485 communication bus 5 sends to signal acquisition module 6 with the RS485 communication signal, and signal acquisition module 6 is carried out the collection of information according to the instruction that system sends.
The utility model is simple in structure, production cost is low, system stability is strong, long service life, is easy to safeguard.
