Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further explained.

Referring to Fig. 1--Fig. 3; In the door status monitoring control system shown in the present embodiment; Door state software for display and door state main frame are mainly through front end monitoring room door 105; And the state that is communicated with the 101 104 pairs of monitoring room doors of door state detector installed with indoor 102 wind field door 103 that leak informaton detects (in the present embodiment, with 104 expression door state detectors, in order to simplify the use of Reference numeral; Be not that each state detector has all marked 104 among the figure); In case front end monitoring room door 105 is opened or is not closed, but door state detector 104 trigger switch amount signals handle through the condition handler 107 that circuit transfers in the Master Control Room, then signal is transferred to a condition managing terminal 108 and shows through software.This system adopts the mode of electronic chart, makes the policeman can see the switch situation of each monitoring room door easily and intuitively, checks the workload of respectively supervising the chamber thereby alleviate the policeman effectively, has improved work efficiency and quality.System has the function with supervisory system interlock in addition, and door condition managing terminal 108 can transfer to the monitor video matrix with an open alarm signal of door 103 that leaks informaton with monitoring room door 105 and carry out the image interlock.When the prison exterior door and the field door that leaks informaton were opened, the cooperative monitoring system 106 of system accessed the external door of corresponding prison chamber and the camera review of the field 101 of leaking informaton automatically in Surveillance center, the situation of monitoring room door unlatching is carried out video check.Below further introduce the workflow of the utility model door status monitoring control system:

With one of them monitoring room door is example illustrative system working condition.As respectively draw among P1.0 in the circuit theory diagrams and the P0.0 line be connected to a certain prison chamber the door state detector; When door is opened; The door state detector state will from often open become normally closed, thereby cause P1.0 and P0.0 short circuit, chip AT89C52 will detect this variation; Can find corresponding prison chamber numbering through the operation of program; Again numbering is sent to the door condition managing software that is moving in the condition managing computer, door condition managing software can be opened according to the position of numbering demonstration prison chamber in the electronic chart of correspondence and with red flash for prompting door, sends instruction cooperative video monitoring matrix accesses corresponding prison chamber automatically in Surveillance center camera review simultaneously; So that carrying out video, the situation that the policeman opens monitoring room door checks, to confirm whether need further process alert.
