Fire emergency lighting detection system Supervision, Inspection and fire emergency lighting industry plays an important role. Fire Electronic Product Quality Supervision and Inspection work also plays a decisive role . The rapid development of electronic technology and control theory , for the manufacture of high-performance , high - index testing equipment developed to provide the necessary conditions . Not high degree of automation of traditional detection methods , some functions rely on manual operation , the collection of data needed to test further processing ; function expansion can not be carried out , can not be completed at the same time the number of test data collection . In order to improve the accuracy of the test data , reduce errors , the automatic detection of a fire emergency lighting system design . The paper first introduced the performance characteristics of the fire emergency lighting and works . Fire emergency lighting testing requirements and key technologies are discussed . In this paper, the design of distributed computer control system , lower machine adopted the PIC16F877A microcontroller as the core processor , completed emergency work time and the termination of the voltage measurement unit , charge and discharge durability test unit , charge and discharge test unit , repeat conversion test unit , static discharge current measurement unit , the communication unit , display and keypad circuit unit circuit design , the next crew using the MPLAB ICD2 development system microcontroller program design , software design and programming of each module is completed . The host computer program using C # . NET language , practical software , user-friendly, easy to operate, powerful storage , computing functions. Completed the following program interface design: Emergency time and termination voltage interface , and charge-discharge durability test interface , and charge-discharge test . Duplicate conversion test interface , and static bleeder current test interface . Monitoring and control system designed entirely by computer to complete the inspection can be realized through the visual interface of the computer all the inspection operations . Greatly improve the level of automation and efficiency of the fire emergency lighting detection system .
