The utility model has the advantages that: for Cold Chain Logistics transit link, adopt GPRS technology, real-time, long distance control system for refrigerating box the temperature inside the box are developed, can monitor in real time the variation of each refrigerating box the temperature inside the box in transit, and the temperature that transfinites (below or above limiting temperature) is carried out and alarm, so that staff adopts an effective measure and reduces the loss in time. Meanwhile, temperature data can remain to persistence in background data base system in time, is convenient to transport the information system management of product data, the inquiry of historical data and recalling.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises: refrigerating box temperature monitoring module, data communication module, remote monitoring maintenance terminal and monitoring central server, described refrigerating box temperature monitoring module is integrated in refrigerating box, data communication module is integrated on refrigerating box housing, be connected with refrigerating box temperature monitoring module, described data communication module passes through GPRS network accessing Internet, then connects described remote monitoring maintenance terminal and monitoring central server. Below each several part is elaborated.
1. monitoring central server (MCS), operates in client's monitoring operation center. Need continuously uninterrupted stable operation in 24 hours, the function of all refrigerating box equipment of monitoring is provided, receive in real time the temperature data that refrigerating box reports and preserve warehouse-in, monitoring refrigerating box state is also reported to the police, for maintain customer end software provides the interface function of management maintenance.
This monitoring central server simultaneously for customization and client's existing information management system to connection function, image data is reported to the existing information management system of client in time, with the existing information management system slitless connection of client, make full use of client's existing resource.
2. remote monitoring maintenance terminal (RMMC), offer management maintenance personnel and carry out system maintenance, management, installation administration software or supporting App is installed on smart mobile phone and can realizes on computers, the functions such as refrigerating box equipment control, refrigerating box device status monitoring, the monitoring of temperature real-time graph, the inquiry of historical data and chart displaying, historical data download and preservation are provided for user, and management maintenance personnel can monitor system in the place of any accessible Internet network.
3. refrigerating box temperature monitoring module (TDU), is integrated in refrigerating box, and the monitoring of the temperature inside the box and data acquisition, preservation, reporting functions are provided. This module is integrated in refrigerating box in advance by refrigerating box equipment manufacturer.
4. data communication module (DTU), provide wireless communication function by GPRS network, realize real-time, the long-range monitoring central server that uploads to of data, and provide network state monitoring and Auto-reconnect function, promptness and the accuracy of guarantee data upload. This data communication module need to be integrated together with refrigerating box, and with the temperature monitoring module collaborative work of refrigerating box self, jointly complete temperature acquisition, report.
GPRS data communication module provides and has comprised that RS232, RS485, tri-kinds of data communication interfaces of TTL and refrigerating box temperature monitoring module carry out data communication, provides 2 tunnel inputs and 2 tunnels output totally 4 way switch amount IO, for refrigerating box temperature monitoring module simultaneously.
Introduce the course of work of the utility model embodiment below in conjunction with Fig. 2.
Medicine refrigerated item (as medicine, blood, blood plasma, vaccine etc.) is loaded into after refrigerating box, the temperature monitoring module being arranged in refrigerating box starts to gather the temperature inside the box and is numbered preservation, the temperature data collecting is sent to monitoring central server by the GPRS data communication module that is integrated into refrigerating box housing simultaneously. Temperature data can be accurate to 0.1 degree.
Data communication module on refrigerating box keeps the communication connection with monitoring central server, the data that report in time temperature monitoring module to send, the communication connection of monitoring and monitoring central server simultaneously, discovering network communication abnormality regularly (can set) initiation reconnects request until successful connection.
Monitoring central server uninterrupted stable operation in 24 hours, receives in time, processes from the temperature data of refrigerating box and be saved in Database Systems, can at least preserve the historical temperature data of nearest 6 months, is convenient to the information system management of data, accident recall inquiry. Monitoring central server normally receives after the temperature that refrigerating box reports, and can return at once the message of confirming that data are received.
Due to the data that a variety of causes does not report in time, monitoring central server can in network service under normal circumstances, be sent and again report the request of omitting temperature data to refrigerating box temperature monitoring module.
For the data communication module of each refrigerating box, the phone number that two temperature over-ranges are reported to the police can be set, after refrigerating box temperature monitoring module monitors the temperature inside the box and transfinites, trigger data communication module sends SMS alarm to the phone number of specifying at once, notifies staff to process in time.
The utility model is monitored for refrigerating box the temperature inside the box targetedly specially, adopt that scheme implementation operation is relatively convenient, scheme cost is relatively little, and can fully effectively utilize the scheme of the existing information management system resource of client, be convenient to client and make full use of existing resource, improve the level of informatization of materials circulation transport field, help client's realize target with less cost.
