The specific embodiment
It is the system of portable refrigerating unit RE1 that Fig. 1 shows a kind of so-called refrigerating chamber unit that is used to be controlled on the tramcar RC1.According to another embodiment of the present invention, tramcar RC1 is lorry or other wheeled apparatus that is loaded with refrigerating unit RE1.Refrigerating unit RE1 comprises a local power switch (local power switch), when this this locality power switch was disconnected, it can make portable refrigerating unit RE1 decommission fully, and, when this this locality power switch was switched on, it allowed this cell operation.Temperature and the running of control module CU1 monitoring refrigerating unit RE1 on tramcar RC1.The antenna AN1 that is connected with control module CU1 makes control module CU1 communicate by letter with remote port (remote station) RST1 by a two-way Radio Link WL1.According to one embodiment of the invention, this Radio Link is end-to-end link (station-to-station link).According to another embodiment of the present invention, this Radio Link WL1 is connected to the other end, is connected to remote port RST1 by other Radio Link or land line (landlines), internet or its then.According to still another embodiment of the invention, this Radio Link WL1 constitutes one or more satellites individually or with other link in combination.In fact, Radio Link WL1 represents a communication system usually.Remote port RST1 can pass through the electric power of Radio Link WL1, antenna AN1 and control module CU1 Long-distance Control supply refrigerating unit RE1.Control module CU1 and switch module (trip module) TM1 acting in conjunction has the final power of closing refrigerating unit RE1 to allow the local maintenance personnel on tramcar RC1.
Fig. 2 and Fig. 3 have disclosed one embodiment of the invention, and it comprises one second gauge tap or a remote control switch, and it is a part of implementing switch module TM1 of the present invention, and operate by control module CU1 via Radio Link WL1.As shown in Figure 2, under common function situation, workman or the site operation people onboard of the local switch LS1 among the refrigerating unit RE1 just keeps the normally closed state after it is closed.Then, electric current flow to refrigerating unit RE1 by battery BA1 through normally closed self-locking cut-out relay (latching killrelay) KR1.Typically, a site operation people disconnected switch LS1 before to the car unloading, connected this switch before car is loaded.
If allow the local switch of refrigerating unit RE1 be in disconnection (OFF) position because of carelessness, can make this unit not have electric power usually, cause refrigerating unit RE 1 not operate.Typically, must send an operator to car, to remove to operate this switch.Switch module TM provides another approach to refrigerating unit RE1 supply capability, that is, and and by remote control switch (remote switch) RS1.This switch RS1 is controlled by long distance wireless link WL1, and being in which kind of state regardless of local switch LS1 can both be to refrigerating unit RE1 supply capability.
The normal operation of refrigerating unit RE1 and switch module TM1 need be reduced to " remote control " position (as shown in Figure 2) with two linked switch MS1 and MS2 this locality of service switch MSW.These switches remain on remote control position, unless they need be opened during maintenance system.Under the sort of situation, indigenous technique person or maintenance personal promote (as shown in Figure 2) to maintenance position with service switch MSW.When service switch MSW was in remote control position, the breech lock RSL1 that a pair of signal on a remote control switch enable line RM1 responds was applied to a positive signal or high signal the control part of remote control switch RS1.This high signal makes remote control switch RS1 closure.When indigenous technique person placed maintenance position with service switch MSW, the negative electrode of diode D1 made the switch MS1 ground connection of the control part of remote control switch RS1 by service switch MSW.So just force the control part of remote control switch RS1 to reduce, and regardless of the order from CU1.When service switch MSW was reduced to as shown in Figure 2 remote control mode, the negative electrode of diode D1 was unterminated, and the control part of remote control switch RS1 receives the high enable signal of locking from the breech lock RSL1 among the control module CU1.
Two inputs that self-locking cut-out relay KR1 correspondence is denoted as 2 (on) and 4 (off) respond.Usually, low-voltage or no-voltage all appear in two inputs.High potential or positive potential at input 4 are locked in open position with cut-out relay KR1.Positive reset potential (positivereset potential) at input 4 will be removed this locking and allow this relay closes.
In case of emergency, site operation people or other people can press the obvious visible button on an instantaneous contact disconnect EK1.Handle this button and make to have positive potential on the input 4 of this self-locking cut-out relay KR1, and it is opened.So just removed electric power from refrigerating unit RE1, and no matter the state of local switch LS1 or remote control switch RS1.Relay KR 1 stays open state until resetting at input 2 clearly, thereby makes the RE1 unit not have electric power and do not operate thus.
Disconnect EK1 connects a positive potential, its be presented at that a disconnect monitoring circuit KM1 goes up and the kill switch monitor in control module CU1 on.Fig. 3 shows the details of control module CU1.Here, the controller CO1 among the control module CU1 automatically sends message by Radio Link WL1, is triggered with warning long-distance service personnel or this disconnect of technician EK1.
There are two kinds of methods that the self-locking cut-out relay KR1 among Fig. 2 is resetted.These two kinds of methods all need local maintenance personal service switch MSW to be set in remote control position.A kind of method that cut-out relay KR1 is resetted is that trained technician at the scene uses the hiding SR on a reset switch HK1 who hides.So just produce positive potential and relay KR 1 is resetted at the input 2 of self-locking cut-out relay KR1 by switch MS1.Other method is, sends signal the trained technician of remote port RST1 by Radio Link WL1, causes controller CO1 to open circuit to reset in remote control and produces positive potential on the circuit RK1.This positive potential appears at the input 2 of self-locking cut-out relay KR1 by switch MS 1.Obtain reset function by said method and be limited to trained especially technician.
If switch MSW is in maintenance position, then diode D2 connects the terminal 2 of the control part of K switch R1, thereby prevents that high signal from arriving the control part of K switch R1, and it is stayed open.Electric power can not be applied on the refrigerating unit RE1 when therefore, neglecting in maintenance process.
Second utmost point MS2 of service switch MSW can also can forbid remote control refrigerating unit RE1 by remote control refrigerating unit RE1.When service switch MSW was in remote control position, utmost point MS2 was connected to transceiver TR1 with Serial Control circuit TX, thereby allowed refrigerating unit RE1 is carried out remote control.When maintenance position, this connection is cut off, and forbids RE1 is carried out any remote control.It is the circuit TX that circuit RX is connected to control module CU1 that second of second utmost point MS2 by service switch MSW connects.So just provide the CU1 switch to be in the indication of maintenance position.
As shown in Figure 3, can control this remote control switch RS1 by control module CU1 by breech lock RSL1.If controller CO1 restarts, then breech lock RSL1 can remember its state.When resetting because of carelessness or restarting controller CO1 among the control module CU1, breech lock RSL1 keeps its state before resetting.If the state before interrupting is high, then latching relay RSL1 closes switch RS1 and provides lasting electric power to refrigerating unit RE1.If the state before interrupting is low, then latching relay RSL1 closes switch RS1 and makes refrigerating unit RE1 keep opening circuit.
Transceiver TR1 forms the part of refrigerating unit RE1, and the function situation of the running unit OP1 in the induction refrigerating unit.Running unit OP1 and the situation of other parts, for example temperature of the microcontroller MCO1 induction refrigerating unit among the refrigerating unit RE1.Transceiver TR1 is sent to controller CO1 among the control module CU1 with situation about sensing.Then, controller CO1 is sent to remote port RST1 with these situations about sensing by transceiver TR2 and antenna AN1.Controller CO1 also is formed with kill switch monitor, and it is by the situation of disconnect monitoring circuit KM1 kill switch monitor EK1.It is sent to remote port RST1 with this situation by transceiver TR2 and antenna AN1.Controller CO1 also is formed with the remote control restorer that opens circuit, and it resets self-locking cut-out relay KR1 by the open circuit circuit RK1 that resets of remote control.It receives reset command from the technician of remote port RST1 by transceiver TR2 and antenna AN1.Controller CO1 also is formed with the remote control switch enabler, and it responds remote port RST1 by transceiver TR2 and antenna AN1, thereby locks by remote control switch enable line RM1 setting breech lock RSL1 and with remote control switch RS1.
Transceiver TR2 among the control module CU1 will send controller CO1 to from all signals of antenna AN1, and all signals of self-controller CO1 send antenna AN1 in the future.
The present invention allows remotely to start or close refrigerating unit RE1 by wireless technology.When normal operation, comprise that the commutation circuit of unit CU1 and switch module TM1 works, so when if indigenous technique person makes " local switch " to be in " off " position because of carelessness on panel, the teleoperator can start native system.In addition, operation control unit CU1 so that the teleoperator can make this unit in running order, and can make it break away from duty.When scene nobody can have when easy-to-use, this teleoperator can use this unit.If the local switch among the switch module TM1 is in on-state, then the teleoperator can close this unit R E1.For final control is provided, be arranged to allow the technician who is operated on this unit guarantee that this unit can not be activated by remote command in circuit.
