Abstract
The utility model discloses a two-bus temperature and humidity monitoring device, particularly to an on-line monitoring system used for monitoring conditions of environment temperature rise of high voltage equipment. The two-bus temperature and humidity monitoring device comprises a host computer and a plurality of slave computers, bidirectional intercommunication between the host computer and the slave computers is realized through connection by two buses, the slave computers and loads are also connected through two wires, the device is provided with the two buses, one of the buses is used for power supply, the other is used for communication, polarity is not distinguished in connection between the host computer and the salve computers, one host computer and one to eight slave computers may be arranged on the buses, each slave computer on the buses has a unique address, and the maximum transmission distance is 100m. The two-bus temperature and humidity monitoring device has the advantages that difference of polarity does not exist in wiring, and the device is not damaged due to wiring errors, and is flexible to use and convenient to install. The two-bus temperature and humidity monitoring device can be widely applied to electric power enterprises.
Description
Technical field
The utility model belongs to field of electrical equipment, refers to be used for the on-line monitoring system of monitoring high-tension apparatus environment temperature rise situation especially.
Background technology
The 11.7.2 regulation will be strengthened the supervision to the operational outfit temperature rise in State Grid's grid company " 18 great anti-accident measures of electrical network ", can be used on the market at present realizing that the product of above-mentioned functions also has a lot of shortcomings when realizing monitoring function, can use the monitoring environment temperature, then exist installed inconvenient part to the product of humidity more, traditional monitoring technique is in case need the environment temperature of monitoring multiple spot, then wiring is miscellaneous and make mistakes easily during humidity, if the control point is in case the phenomenon that the work at present demand will occur satisfying is installed in change at most, also make mistakes easily to requiring of installing is cumbersome, cause the inconvenient and damage easily of installation of equipment, and use also underaction.
The utility model content
The utility model is at the shortcoming of prior art, and purpose is to provide a kind of convenient installation, and wiring is not easy to make mistakes and environment temperature, humidity control device that can flexible combination.
For realizing that the utility model purpose adopts following technical scheme: a kind of two bus temperature and humidity monitor devices, it comprises main frame, slave (comprise communication module, Temperature Humidity Sensor etc., slave can increase and decrease according to actual operating position), three parts of load.
A kind of two bus temperature and humidity monitor devices comprise main frame, slave, it is characterized in that: main frame and slave are connected by two buses realizes two-way intercommunication, also is to be connected by two lines between slave and the load, and slave has several.
As preferably, the bus in above-mentioned a kind of two bus temperature and humidity monitor devices has two lines, and wherein one always through being for power supply, and another root bus is for communication.
As preferably, main frame is not distinguished polarity with being connected of slave in above-mentioned a kind of two bus temperature and humidity monitor devices.
As preferably, on the bus main frame is arranged in above-mentioned a kind of two bus temperature and humidity monitor devices, slave has the 1-8 platform, and the slave of each on the bus has a unique address, maximum transmission distance 100m.
Described main frame is positioned at the front of cabinet; Slave is positioned on the control point; Load is positioned on the limit, control point.
Beneficial effect: the utility model is compared with existing ambient temperature and humidity supervising device, and its advantage is:
1, wiring does not have polarity, can not damage because wiring error causes device.
2, use is flexible, only needs two buses can realize the slave expansion, need get final product with regard to hang a slave on bus a control point, can adjust the ambient temperature and humidity monitoring flexibly according to field condition and count.
3, easy for installation, wiring only needs two buses to get final product, and has saved wiring and time and the cost installed greatly.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Embodiment 1
As shown in Figure 1, make two bus temperature and humidity monitor devices, comprise main frame, slave, wherein main frame is connected the two-way intercommunication of realization with slave by two buses, also be to be connected by two lines between slave and the load, bus has two lines, and wherein one always through being for power supply, and another root bus is for communication; Main frame is not distinguished polarity with being connected of slave; A main frame is arranged on the bus, and slave has 2, and the slave of each on the bus has a unique address, maximum transmission distance 50m.During use: the front that main frame is installed in monitored cabinet; Slave is installed on the monitored point, and a slave is installed in a plurality of then each control point; Load of each slave band, load be installed in control point next door or below.
Embodiment 2
As shown in Figure 1, make two bus temperature and humidity monitor devices, comprise main frame, slave, wherein main frame is connected the two-way intercommunication of realization with slave by two buses, also be to be connected by two lines between slave and the load, bus has two lines, and wherein one always through being for power supply, and another root bus is for communication; Main frame is not distinguished polarity with being connected of slave; A main frame is arranged on the bus, and slave has 6, and the slave of each on the bus has a unique address, maximum transmission distance 100m.During use: the front that main frame is installed in monitored cabinet; Slave is installed on the monitored point, and a slave is installed in a plurality of then each control point; Load of each slave band, load be installed in control point next door or below.
This device only needs two lines just can realize the detection of 1-8 road temperature and humidity, controls the load of 1-8 road correspondence simultaneously, user's slave quantity of can freely arranging in pairs or groups.This product adopts MCU to gather automatically, analyze, judge whether current humiture surpass that the user arranges opens the control value, thereby handles it, and temperature range is at-20 ℃～100 ℃, and humidity range is at 25-100%RH.Display window adopts liquid crystal display (160*128), the current monitor state of more directly perceived, detailed reaction, and open functions such as history curve, history table, the user can view the variation of temperature, humidity very intuitively.
