Abstract

The utility model provides a bus temperature monitoring system, which comprises an acquiring device and a monitoring device, wherein the acquiring device is connected with the monitoring device, acquires bus temperature data and bus environment temperature data, and transmits the acquired data to the monitoring device; and the monitoring device analyzes and displays the bus temperature data and the bus environment temperature data. The bus temperature monitoring system acquires the temperature data of the environment of the bus in addition to the bus temperature data, and the unusual judgment on the bus temperature is more accurate by comprehensively considering impact of bus environmental factors on the bus. When a temperature sensor transmits the acquired temperature data to a temperature indicator, a DeviceNet network is adopted so as to avoid interference on data transmission, and the data is more reliable.

Description

The bus temperature monitoring system

Technical field

The utility model relates to the electric power monitoring field, in particular to a kind of bus temperature monitoring system.

Background technology

Switch cubicle is a most frequently used electrical equipment in industry and the civilian distribution system.Bus is as the part of switch cubicle, is used for transferring electric power.Problems such as surface oxidation burn into fastening bolt is loosening, the junction is aging can appear in bus in the long-time running process, cause busbar overheated even catastrophic failure occurs.Therefore all need to measure bus temperature every day, overheated to prevent bus temperature.

Fig. 1 shows the bus temperature monitoring system synoptic diagram of prior art, as shown in Figure 1, after the collection of bus temperature process radio temperature sensor data is sent to temperature indicator, and temperature indicator sends to higher level's supervisory system again.

Existing bus temperature detection system has the following disadvantages at least: existing bus temperature monitoring system is not taken all factors into consideration the temperature of bus environment of living in, makes that the unusual judgement of bus temperature is not accurate enough; When radio temperature sensor transmitted the bus temperature of being gathered to temperature indicator, what adopted was wireless network, and the transmission of data is interfered easily; The network interface that temperature indicator is supported is few, is difficult to merge with the multiple network system.

The utility model content

Technical problem to be solved in the utility model provides a kind of bus temperature monitoring system to the unusual accuracy of judgement of bus temperature, and this system synthesis has considered that environment factor is to the unusual influence of bus temperature.

In order to solve the problems of the technologies described above, the utility model provides a kind of bus temperature monitoring system, comprising: harvester, link to each other with monitoring device, gather bus temperature data and bus ambient temperature data, and with the data transmission of being gathered to monitoring device; Monitoring device is analyzed and demonstration bus temperature data and bus ambient temperature data.

Further, monitoring device comprises the display module that is used to show bus temperature data, bus ambient temperature data and monitoring result.

Further, harvester links to each other by the DeviceNet network with monitoring device.

Further, the bus temperature monitoring system also comprises: control device, and control device links to each other with monitoring device, according to exporting control signal from the monitoring result of monitoring device input; Alarm module is connected with control device, receives control signal and carries out alarm operation.

Further, harvester is a temperature sensor.

Further, monitoring device is a temperature monitor.

Further, control device links to each other by following a kind of network with monitoring device: ControlENT (towards the real-time fieldbus networks of key-course), Profibus-DP (Profibus Decentralized Perphery, the distributed peripheral hardware of Profibus) or Ethernet.

Further, control device is a computing machine.

Adopt the bus temperature monitoring system of said structure to have following beneficial effect:

1. bus temperature monitoring system of the present utility model has also been gathered the temperature data of bus environment of living in except gathering the bus temperature data, by taking all factors into consideration the influence of the residing environment factor of bus to bus, make that the unusual judgement of bus temperature is more accurate.

2. temperature sensor is when temperature indicator transmits the temperature data of being gathered, and what adopted is the DeviceNet network, makes the transmission of data be difficult for being interfered, and data are more reliable.

3. temperature monitor is supported the multiple network interface, can be (for example by multiple network, ControlNET, ProfibusDP, Ethernet) data are sent to control device, make bus temperature monitoring system of the present utility model to merge with the multiple network system, increased the dirigibility of system.

Description of drawings

Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:

Embodiment

Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.

Fig. 2 shows bus temperature monitoring system structured flowchart of the present utility model.As shown in Figure 2, this bus temperature monitoring system comprises temperature sensor 100, temperature monitor 200, computing machine 300, DeviceNet network 400 and Ethernet 500.

Bus temperature sensor 102 and 106 is used for gathering in real time the temperature of bus, selectively is arranged at the different temperatures collection point of the busbar in the switch cubicle.Bus

environment temperature sensor
