Description
Technical field
The utility model electronic surveying and display device belong to technical field, and in particular to a kind of linear alternating message source.
Background technology
Linear alternating message source is a kind of common signal source, and it is real to be widely used in scientific research, production practices and teaching
Test etc. in field, the particularly scientific experiment of communication system.Linear alternating message source produces sine wave, after the amplification of high pressure amplifier
Output, enables signal to have good output performance and system stability.The linear alternating message source of various models has one
Fixed storage temperature, such as exceedes the temperature, may cause the damage of linear alternating message source；In addition, the contribution margin meeting of light
Influence the error in reading to linear alternating message source display；And when some have the laboratory applications of vibrations, linear exchange
The damping effect of signal source is poor, directly affects its reading.
Utility model content
The purpose of the utility model is to overcome existing linear alternating message source can not forecast that temperature, display are poor in light
In the environment of reading there are the problem of error and poor damping effect.
For this reason, the utility model provides a kind of linear alternating message source, including circuit board, dress is further included on circuit boards
And PLC is electrically connect with the temperature sensor of circuit board electrical connection, the temperature sensor, PLC electrically connect liquid crystal display
And alarm；
The circuit board, temperature sensor and PLC are encapsulated in linear alternating message source housing.
The embedding slot being recessed inwardly is opened up on the side panel of the housing, liquid crystal display is installed in the embedding slot,
Alarm is installed on the side panel.
The control panel of linear alternating message source is further included, control panel is equipped with square oscillography display, and oscillography is shown
Show that the position on four sides of device is installed with intilted four shadow shields.
The oscillography display surrounding four slots parallel with four side of oscillography display, four screenings along its edge
Tabula rasa is inserted in corresponding slot, and each shadow shield is inserted in the both ends on the side of slot and is stuck in slot, the width of shadow shield
Depth of the degree more than slot.
The foot pad installed in housing lower face corner is further included, foot pad is rubber material, is opened up thoroughly at the center of foot pad
Stomata.
The beneficial effects of the utility model：This linear alternating message source provided by the utility model, temperature sensor are adopted
Collector plate temperature simultaneously transfers data to PLC, PLC compared with the data of storage, as temperature exceed circuit board bearing temperature,
Alarm is then sent by alarm, actual temp is otherwise shown by liquid crystal display, operating personnel can intuitively learn electricity
The temperature of road plate；In addition the sunshading board on oscillography display solves the digital independent under the poor environment of light, while foot pad
Design expands the use scope of linear alternating message source, is used in the environment of having vibrations, also ensures that linear friendship
Flow the stability of signal source.
The utility model is described in further details below with reference to attached drawing.

Embodiment
Embodiment 1：
As shown in Figure 1, a kind of linear alternating message source is present embodiments provided, including circuit board 1, further include mounted in circuit
The temperature sensor 2 being electrically connected on plate 1 and with circuit board 1, the temperature sensor 2 electrically connect PLC3, and PLC3 electrically connect
Liquid crystal display 4 and alarm 5；The circuit board 1, temperature sensor 2 and PLC3 are encapsulated in linear alternating message source housing 6
It is interior.
2 collecting circuit board of temperature sensor, 1 temperature simultaneously transfers data to PLC3, and PLC is compared with the data of storage, such as temperature
Degree then sends alarm, while show specific temperature by liquid crystal display 4 more than the bearing temperature of circuit board 1 by alarm 5
Degree, operating personnel can intuitively learn the temperature of circuit board 1, make corresponding processing to linear alternating message source in time.
Embodiment 2：
On the basis of embodiment 1, as shown in Fig. 2, opening up the embedding slot being recessed inwardly on the side panel of the housing 6
7, liquid crystal display 4 is installed in the embedding slot 7, and alarm 5 is installed on the side panel.
Embodiment 3：
On the basis of embodiment 1, as shown in Fig. 2, further including the control panel 8 of linear alternating message source, control panel 8
Square oscillography display is equipped with, the position on four sides of oscillography display is installed with intilted four shadow shields 9.Shading
Plate 9 can block the strong light of surrounding, easy to see the sine wave on oscillography display clearly.
Embodiment 4：
On the basis of embodiment 3, the oscillography display surrounding along its edge and is put down with four side of oscillography display
Four capable slots, four shadow shields 9 are inserted in corresponding slot, and the both ends on each shadow shield 9 side for being inserted in slot are equal
