The utility model discloses a realize through following technical scheme:
the utility model provides a warehouse humidity automatic control system, automatic control system is including setting up the dehumidifier in the warehouse, automatic control system still includes programmable controller, temperature and humidity sensor and monitoring host, the monitoring host is located the monitor chamber, dehumidifier, programmable controller, temperature and humidity sensor all set up in the warehouse, programmable controller passes through the ethernet mouth and is connected with the communication of monitoring host, temperature and humidity sensor, dehumidifier are connected with programmable controller respectively, programmable controller gathers the humidity value that temperature and humidity sensor detected through the 485 bus to open and close of dehumidifier is controlled according to the size of the humidity value of gathering.
Furthermore, the temperature and humidity sensors comprise three temperature and humidity sensors which are connected in parallel and then connected with the programmable controller through a 485 bus.
Furthermore, the programmable controller is connected with the dehumidifier through an output signal line, a relay is arranged on the output signal line, and the programmable controller controls the on-off of the dehumidifier through controlling the relay.
Compared with the prior art, the utility model has the following advantages:
the utility model provides a pair of warehouse humidity automatic control system, its control system through constituteing with Programmable Logic Controller (PLC), dehumidifier, temperature and humidity sensor and monitoring host can be greater than opening of setting value automatic control dehumidifier according to warehouse humidity and stop, need not frequent inspection of personnel and operation. The stability of warehouse humidity control is guaranteed, and the manual workload is reduced. Just the utility model discloses simple structure, it is with low costs.

Fig. 1 is a schematic structural diagram of the present invention.
Reference numbers in the figures: 1 monitoring host, 2 programmable controller, 3 temperature and humidity sensor, 4 relay, 5 dehumidifier.
Detailed Description
The embodiments of the present invention will be described in detail below, and the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
Referring to fig. 1, the embodiment discloses an automatic control system for the humidity of a warehouse, the automatic control system comprises a dehumidifier 5 arranged in the warehouse, the automatic control system further comprises a programmable controller 2, a temperature and humidity sensor 3 and a monitoring host 1, the monitoring host 1 is located in a monitoring room, the dehumidifier 5, the programmable controller 2 and the temperature and humidity sensor 3 are all arranged in the warehouse, the programmable controller 2 is in communication connection with the monitoring host 1 through an ethernet port, the temperature and humidity sensor 3 and the dehumidifier 5 are respectively connected with the programmable controller 2, the programmable controller 2 collects the humidity value detected by the temperature and humidity sensor 3 through a 485 bus, and controls the on and off of the dehumidifier 5 according to the collected humidity value.
The temperature and humidity sensors 3 are connected in parallel and then connected with the programmable controller 2 through a 485 bus. The programmable controller 2 is connected with the dehumidifier 5 through an output signal line, a relay 4 is arranged on the output signal line, and the programmable controller 2 controls the on-off of the dehumidifier 5 through controlling the relay 4.
In this embodiment, the programmable controller 2 is a 485 communication interface, an ethernet port, and a digital input/output point type programmable controller 2, and the type s7 — 200smart programmable controller 2 can be used. The programmable controller 2 is in communication connection with the monitoring host 1 through the Ethernet. The three temperature and humidity sensors 3 are connected in parallel and then connected with a 485 interface of the programmable controller 2 through a 485 bus. The programmable controller 2 is externally connected with an output signal line through a Q0.0 point so as to be connected with the dehumidifier 5, and an operation signal of the dehumidifier 5 is input into the programmable controller 2 through an I0.0 point of the programmable controller 2.
When the humidity control device works, the humidity of a warehouse is detected through the temperature and humidity sensor 3 and is transmitted to the programmable controller 2, when the detected humidity is higher than a set value, the programmable controller 2 starts the dehumidifier 5 for dehumidification through the control relay 4, and when the detected humidity is equal to or lower than the set value, the programmable controller 2 controls the dehumidifier 5 to stop through the control relay 4.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
