State the first ring current verification relay J I normally-closed contact J I -1 both ends.
Each driving face is provided with by the local fan main frame and local fan standby host of a magnetic starter control,
Therefore, each circuit supervision module of the embodiment of the present invention can monitor a magnetic starter of a driving face（Such as
QBZ—2×120、80/1140（660）SF types blower fan double power source vacuum electromagnetic starter）, i.e. two local fans.Therefore,
I.e. the present embodiment can monitor the working condition of 6 local fans of 3 driving faces simultaneously.In addition, circuit supervision module
The quantity quantity of driving face that can also be monitored as needed set, can be 1,2 or be greater than 3
It is individual.
The operation principle of the present invention is as follows：Under normal circumstances, the main frame operation of blower fan, the powered stand-by heat of standby host.Work as main frame
Or the preceding blower fan of standby host（Or preceding blower fan and rear fan）During normal operation, the auxiliary contact of corresponding controller of fan（KM1、
KM2、KM3、KM4）Closure, corresponding relay connected in series（J1 、J2、J3 、J4）Obtain electric, corresponding indicator lamp（L1、
L2、L3、L4）It is bright, corresponding relay normally closed contact（J1-1 、J2-1、J3-1 、J4-1）Disconnect, circuit where audible-visual annunciator Y
Access failure is not alarmed；When the same one-level blower fan of main frame breaks down or powered off, the auxiliary contact of corresponding controller of fan
（KM1、KM2）Disconnect, corresponding relay connected in series（J1、J2）Power-off, corresponding indicator lamp（L1、L2）Extinguish, it is corresponding
The normally-closed contact of relay（J1-1 、J2-1）Closure, because now guest machine does not work, then it is normally closed to power off its by relay J3, J4
Contact（J3-1 、J4-1）Closure, circuit where audible-visual annunciator Y being connected, audible-visual annunciator Y sends sound and light alarm, while accordingly
It is identified with certain working face printed words（Such as 8106 working faces or 8110 air way working faces）Red portable blower fault alarm indicator lamp YL
Flash it is shinny, prompt blower fan caregiver pay attention to inspection handle；If now blower fan can automatically switch to standby host and work on,
So, the auxiliary contact of the controller of fan of standby host（KM3、KM4）Closure, corresponding relay connected in series（J3 、J4）
Electricity, corresponding indicator lamp（L3、L4）It is bright, disconnect the normally-closed contact of corresponding relay（J3-1 、J4-1）, audible-visual annunciator Y institutes
It is disconnected in loop, alarm stops；If now blower fan can not automatically switch to standby host, audible-visual annunciator Y will persistently alarm,
Until pressing SR K3, or blower fan recovers to run well.
, wherein it is desired to according to the size of driving face and progress situation, it is determined whether need to open two level（Motor afterwards）
Ventilation blower, if necessary to open, then main frame rear fan selecting switch K4, standby host rear fan selecting switch K5 are closure state, such as
Fruit need not open, then main frame rear fan selecting switch K4, standby host rear fan selecting switch K5 are off-state, to prevent from reporting by mistake
Alert condition occurs.
When fan trouble investigates processing, in order to reduce alarm noise, reset switch K3 can be pressed, makes acousto-optic report
Alert device Y stop alarms.Now, malfunction indicator lamp LY still flashes, power transfer relay 5J still adhesives, until failure is thoroughly arranged
Remove.
Further, the embodiment of the present invention can also include the local fan main frame for being separately positioned on each driving face
The second air duct blast switch K2 at the first air duct blast switch K1 and local fan standby host at place, the circuit supervision module is also
Including the main frame air duct blast indicator lamp LK1 and standby host air duct blast indicator lamp LK2 being arranged on housing, the first air duct wind
Compress switch after K1 connects with main frame air duct blast indicator lamp LK1 and be connected in parallel on the normal of the second servo loop Power Supply Monitoring relay J II
Closed contact J II -1 both ends；The second air duct blast switch K2 is connected in parallel on institute after being connected with standby host air duct blast indicator lamp LK2
State the first ring current verification relay J I normally-closed contact J I -1 both ends；As shown in figure 5, it is air duct blast switch K4 or wind
Cylinder blast switch K5 structural representation, including skeleton 41, draw ring 42, switch connection box 43, dry spring positioned at the both ends of skeleton 41
Pipe switch 44, magnetic induction plate 45 and spring 46, as shown in fig. 6, being the mounting structure schematic diagram of air duct blast switch, band 48 is logical
Cross draw ring 42 by the first air duct blast switch K1 and the second air duct blast switch K2 be bundled in respectively local fan main frame and
On the air duct 47 of local fan standby host.
When fan switch is working properly, and for some reason（Leak out, rotating speed is low, fan damage, air duct depart from etc.）Lead
When causing air duct blast deficiency, air duct will be relaxed, and blast switch K on air duct is bundled in spring 6 by draw ring 2 with band 8
In the presence of, tablet 5 is resetted close to tongue tube 4, its contact closure has been connected alarm circuit, corresponding air duct blast instruction
Lamp（LK1、LK2）Luminous, audible-visual annunciator Y sends alarm, prompts blower fan caregiver to carry out inspection processing, prevents power failure blowing-out
Accident occurs.
Further, as shown in Fig. 2 the circuit supervision module also includes alarm relay J5, the portable blower failure report
After alert indicator lamp LY and alarm relay J5 series connection, reset switch K3 and audible-visual annunciator the Y both ends, the alarm are connected in parallel on
Relay J5 normally opened contact is used to be used as failure output relay contact.The fault-signal can be timely by mine communication network
Fault-signal is uploaded to team's night shift room or ore deposit control room, commander department is accurately grasped Underground Local Fan operation feelings in real time
Condition.
A kind of remote centralized control apparatus of driving face local fan proposed by the present invention, it is possible to achieve local fan
