Abstract
The utility model relates to a patrol monitoring display which is suitable for railways, warehouses and other places needing timing patrol and examination, belonging to a device which is composed of electronic elements and can display data received and stored by a corresponding recorder. The utility model is characterized in that the utility model is provided with a main control circuit with a monolithic computer, which is respectively connected with a display circuit, a power supply detecting circuit and a control key and also connected with a patrol monitoring and recording device by a splicing type recorded information receiving end arranged on the utility model to together complete the monitoring for patrol examination work. The utility model adopts a non-conducting wire transmission method and has the advantages of simple structure and convenient use and carrying, and the utility model overcomes the defects that the length of a wire is increased with the increase of points in traditional wire transmission type monitoring devices.
Description
The utility model relates to a kind ofly to be made up of electronic component, can show the device of patrolling and examining the information of patrolling and examining that the monitoring recording device receives and store accordingly, is applicable to that railway locomotive, circuit and all kinds of warehouse, goods yard etc. need regularly patrol and guard the place of inspection.
At present, for the personnel of patrolling and examining, can night watchman in accordance with regulations to respectively patrolling and examining the monitoring apparatus that a little carries out tours of inspection work, the wired formula of many employings, promptly will be arranged on the switching device of checkpoint by lead and indoor testing fixture couples together, the checkpoint is many more far away more, and lead is just long more, limited by external condition, and the equipment complexity, function is poor, and is also unreliable.
The purpose of this utility model is exactly to overcome the shortcoming that above-mentioned wired supervision equipment exists, design a kind of can with application number for " 95228700.5 " patrol and examine that the monitoring recording device matches, no lead transmission mode patrol and examine the supervision display device, this device can will be patrolled and examined the information of respectively patrolling and examining a little that the monitoring recording device receives and store and be shown, so that work is patrolled and examined in inspection.
The purpose of this utility model can realize in the following manner.
Be provided with the governor circuit 4 of single-chip microcomputer, connect display circuit 5, power sense circuit 6, key control circuit 7 respectively, governor circuit 4 also is provided with recorded information receiving end 8, is provided with the automatic power-down circuit of ON-OFF control circuit and power supply in the power sense circuit 6.When recorded information receiving end 8 and number of patent application are patrolled and examined the monitoring recording device when being connected for the name of " 95228700.5 " is called, storage a little the information of respectively patrolling and examining within it can be write and originally patrol and examine the supervision display, after data processing, conversion, these data are shown on LCDs one by one, so that managerial personnel understand, check.
The utility model adopts electronic component structure simple, stable performance; Adopt no lead transmission mode, carry, easy to use; Be provided with LCD, directly perceived, automatic circuit break function is arranged, conserve batteries.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model schematic appearance;
Fig. 2 constitutes block diagram for the utility model circuit;
1-display screen among the figure, 2-button, 3-housing, 4-governor circuit, 5-display circuit, 6-power sense circuit, 7-key control circuit, 8-recorded information receiving end.
Fig. 3 is the circuit theory diagrams of an embodiment.
In the present embodiment, governor circuit 4, the structure of power sense circuit 6 and number of patent application are basic identical for " 95228700.5 " name is called the related circuit of patrolling and examining the monitoring recording device.The chip IC 2 of governor circuit 4 adopts PIC16C84, the chip IC 1 of power sense circuit 6 is MAX856, adopt the on-off mode voltage stabilizer of N-channel MOS FET, boost, voltage stabilizing, the formation of ON-OFF control circuit that it is established in addition and the automatic power-down circuit of power supply is, external power E is connected with the port RB0 of governor circuit 4 through switch S 4, and the port RB3 of governor circuit 4 connects the base stage of transistor G1, its collector connects the base stage of transistor G2 again, and the emitter of transistor G2 meets external power E.Display circuit 5 is made up of data converting circuit IC3 and 16 LCD LCD, and chip IC 3 adopts the 74HC164 integrated package.Recorded information receiving end 8 adopts connector.
Principle of work is as follows: operating personnel couple together originally patrolling and examining supervision display and the number of patent application monitoring recording device of patrolling and examining for " 95228700.5 " by connector 8, press power button S4, energized, press control button S1 again, S2, S3 carry out operations such as timing, fox message, removing, then governor circuit 4 corresponding port RA3, RA0, RA1 discern the operation of each button, by port RB1, RB2, connector 8 carries out serial communication with the clock memory circuit of patrolling and examining in the monitoring recording device, reads, writes corresponding data.Be the data conversion that reads the video data of certain format simultaneously, port RA2, RB4 serial by governor circuit 4 is sent to the data converting circuit IC3 in the display circuit 5, data after conversion are delivered to the FPDP of LCD LCD, and governor circuit 4 is finished demonstration work by port RS, R/W, the E of its port RB5, RB6, RB7 control display ICD again.
In power sense circuit 6, when clicking button S4, power supply is powered to chip IC 1 through diode D1, through its boost, after the voltage stabilizing to each circuit supply, it is high level that governor circuit 4 gets electric rearmounted port RB3, then makes triode G1, G2 conducting in succession, the power supply sustainable supply.After pressing the S4 key once more, produce an electric saltus step from low to high at the port RB0 of governor circuit 4, cause interruption, then port RB3 becomes low level, causes triode G1, G2 to end, and power supply disconnects behind the reverse keys S4, realizes the control power switch thus.In addition, by timing of software set, if there is not any button operation in this timing, then to put port RB3 automatically be low level to governor circuit 4, realizes automatically cutting off power source.
