Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.

Fig. 1 is the schematic diagram monitoring system according to cold closet of the present utility model.As it is shown in figure 1, the data collected by acquisition terminal 100 from cold closet 400 through the process of control case 200, eventually through wireless transport module 240 transmission to the host computer as reception display module 300.Specifically, acquisition terminal 100 is connected to cold closet 400, and by 485 serial ports and middle control case 200 wired connection, acquisition terminal 100 by collect from cold closet 400 include the case number (CN) of cold closet 400, control case 200 processes during the cold closet data of temperature and humidity are transferred to.In the embodiment shown in fig. 1, acquisition terminal 100 includes shell, 232 chip 110 and 485 chips 120, cold closet data, through the transfer transmission of 232 chips 110 to 485 chips 120, and then are transmitted to middle control case 200 by 485 chips 120 by data receiver Serial Port Transmission to 232 chips 110.Staff is only needed terminal to be inserted on the communication serial port on cold closet 400 after cold closet 400 arrives harbour, easy to operate.One acquisition terminal 100 is capable of identify that the cold closet 400 of multiple different brands, such as same acquisition terminal 100 can recognize that the ice chest that the market accountings such as TK, Carrier, StarCool, DK are relatively larger, therefore by different terminals and changes software without the need to distinguish different brands frequently when gathering data.

Middle control case 200 includes casing 210, receiver module 220, Centralized Controller module 230, power module 250 and wireless transport module 240.In embodiment of the present utility model, receiver module 220 is 485 modules for receiving from the cold closet data of acquisition terminal 100 and transmitting it to Centralized Controller module 230.Centralized Controller module 230 comprises multiple terminal controller 231 and a master controller 232, wherein terminal controller 231 is set to according to set agreement, cold closet data are decoded Unified coding respectively again, multiple terminal interface drawn by multiple terminal controllers 231 and 485 modules connect, master controller 232 is for collecting the cold closet data of multiple terminal controller 231, and transmits it to reception display module 300.External 220V voltage can be converted to 12V, 5V and 3.3V voltage by power circuit, to supply different controllers.The transmission of cold closet data is extremely received display module 300 by wireless transport module 240 by master controller 232.In one embodiment, wireless transport module 240 comprises network interface module 241 and the such positioner 242 of such as GPRS module, for being wirelessly transferred cold closet data and the positional information of middle control case 200 to accepting display.In another embodiment, middle control case 200 has 24 terminal interfaces, and namely control case 200 can connect 24 acquisition terminals 100 in one.

Also including relay 260 in middle control case 200, this relay 260 is for remotely controlling the on an off of cold closet 400.

Acquisition terminal 100 sends, by 485 serial ports, the data received to central controller and processes, the central controller data to sending according to after set protocol code by the mode of Ethernet or CDMA transfer data to Surveillance center be analyzed display.The display module 300 that receives of Surveillance center arranges and stores the cold closet data from middle control case 200, chooses for user and passes through man machine interface and understands current state and the historic state of cold closet 400.

It addition, middle control case 200 also comprises LED circuit, LED bright light prompting when central control case 200 is with acquisition terminal 100 successful connection.

Attractive in appearance in order to facilitate, acquisition terminal 100 is set to the form of plug, by being connected with cold closet 400 in the communication interface of insertion cold closet 400.And the shell of acquisition terminal 100 is made up of waterproof material so that it is more robust, it is possible within 24 hours, be connected on cold closet 400, it is not necessary to take off, and terminal is furnished with automatic wire-collecting box, decrease the trouble of coiling.Central controller shell also can be made up of waterproof material, and is fixed on the iron prop in the middle of cold closet 400 aisle, the acquisition terminal 100 near convenient connection.

The wireless transmission method that Ethernet and CDMA combine is used to reduce the campus network produced.General port and pier all can be coated with wireless network, and middle control case 200 can be connected with the computer acquirement of office either directly through Ethernet, and CDMA is alternative scheme.Before on the market some monitoring cold closet 400 equipment use be exactly CDMA transmit data, these equipment can be directly installed on casing 210, no matter which chest can receive data at, but this can produce substantial amounts of campus network, especially the place of cold closet 400 is not fixed, can outside other provinces, city even at abroad, then the campus network of generation is exactly expensive.Monitoring system disclosed in the utility model not only reduces outfit and the labor intensity of dock personnel, more increases economic efficiency.

In this utility model, identifying that a cold closet required time is about 10 seconds, therefore the renewal time of cold closet data may be configured as 10 seconds.The operation of system allows temperature to be-40～60 DEG C, and running and allowing humidity is 0%-100%, it is possible to properly functioning under the natural environment of harbour.

Embodiment described above only have expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
