the cold storage is provided with a central controller, and the central controller is connected with the data acquisition device;

the GPRS data exchanger enters the internet through the GPRS gateway to exchange data with the server.

Further, the GPRS data exchanger is provided with a terminal number and a server IP address.

Furthermore, the pressure sensor, the temperature sensor and the flow sensor are connected with the data acquisition device through shielded cables.

Furthermore, the central controller is connected with the GPRS data exchanger through a conversion adapter from a peripheral port to a serial port.

Further, the central controller is a refrigeration house controller.

Further, the freezer is equipped with freezer remote control ware, freezer remote control ware is connected and is equipped with control panel.

Compared with the prior art, the beneficial effects of the utility model are that:

the cold storage controller can detect the data such as temperature, pressure, flow, currently set running mode, target temperature and the like of each controlled point of the cold storage unit through a related acquisition device;

the acquired data can be collated and judged whether to have a fault through the controller, and if the data have the fault, a corresponding fault code is generated;

the system comprises a fault code (under the condition of fault), control parameter data which is set in advance and stored in a controller and refrigerator unit basic information (including information such as unit number, unit model, SIM card number and GPRS hardware number), wherein a mountain GPRS data exchanger enters an internet through a GPRS gateway of a GPRS network operator to exchange data with a specified webpage server;

the device can carry out remote measurement, remote signaling, remote control and remote regulation on the refrigeration house through a wireless network. Has reliable performance of industrial grade. Can meet the temperature control requirement of the user environment. When the cold storage runs, various running parameters are collected and set by a relevant collector in the cold storage unit, and fault parameters are transmitted to the server together through the GPRS data transmission network, and a user and a maintainer can inquire after logging in the server. The on-off control, setting parameter adjustment and function control of the refrigeration storage unit by a user and a maintainer are also adjusted on the server and are sent to the refrigeration storage unit by the server through a GPRS data transmission network. The device can be coordinated with a building management system, the occurrence of the faults of the refrigeration house unit can be effectively reduced, the optimal control of the unit is achieved, and the device has the characteristics of no region limitation, simplicity in installation, stability, reliability, economy, practicality and the like.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1, please refer to fig. 1-3:

a remote monitoring device system for a refrigeration house is characterized in that a pressure sensor, a temperature sensor and a flow sensor are respectively arranged on an outdoor circulating system and each circulating system of the refrigeration house, the pressure sensor, the temperature sensor, the flow sensor and a data acquisition device are connected and used for acquiring environmental data and refrigeration house system data, and the data acquisition device transmits the acquired data to a central controller of the refrigeration house;

a server is arranged on a PC platform of the refrigeration house and is connected with a plurality of client terminals; a GPRS data exchanger is also arranged;

the pressure sensor, the temperature sensor and the flow sensor are connected with the data acquisition device, acquired data are transmitted to the central controller through a data acquisition device processing system bus, the central controller transmits the data to the GPRS data exchanger, the GPRS data exchanger enters the internet through the GPRS gateway to perform data exchange with the server, the GPRS data exchanger sends data packets to the server, the GPRS data exchanger sends the data packets to control panels of equipment such as a refrigeration house when receiving the data of the server, and bidirectional cross type data exchange is achieved.

The working principle is as follows:

the server is installed on a PC platform provided by a freezer manufacturer. And adding a maintenance personnel account and a password, and distributing the account name and the password to corresponding maintenance personnel. And after the refrigerator set is installed and debugged, the GPRS data exchanger is installed in the refrigerator, and the terminal number and the server IP address are set. And then contacting with a manufacturer, and adding the information of the refrigeration house in the server by a server administrator to help complete the registration of the SIM card number and the binding of the GPRS hardware ID number, and distributing the work of corresponding maintenance personnel and the like.
