In the present embodiment, MCU is connect by serial communication interface with UPS, and MCU is prolonged by Serial Port Line RS232 to UPS transmission
The instruction of Shi Guanji, certain UPS are the UPS with RS232 interface.The concrete model of UPS is SURT1000XLICH.
In order to which the shutdown to computer equipment is controlled well, in the present embodiment, MCU is connected with shutdown control mould
Block, shutdown control module include key, and key connects MCU by detection circuit as shown in Figure 7, passes through pressed key press time
The shutdown of one key is still orderly shut down when length judges, and then protects computer equipment well.
The working principle of this system are as follows:
In system worked well, electric power plug socket is whole system power supply by UPS and charges to UPS.Work as system
Suddenly after power-off, power supply controls detection module by the state-detection of real-time detection electric power plug socket to power-off, and power cut-off information is led to
It crosses Serial Port Line RS232 and sends cut-offing instruction to MCU, while UPS is powered to MCU and equipment 1 with equipment 2, so respectively setting
It is standby to be powered off due to abnormal shutdown because suddenly.The control of relay is driven by triode after MCU receives cut-offing instruction
Coil electrification, and then the contact generation of relay acts (while indicator light is bright), each equipment collects corresponding relay contact hair
After lively work, saves computerized information and voluntarily shut down within the set time, such as shut down after 60s.Optic coupling element simultaneously
The contact action message for acquiring relay is sent to MCU, and MCU, which receives relay contact action message, ensures that relay contact is sent out
It is lively to make, if MCU does not receive relay contact action message, relay coil electrification is controlled again.Ensuring relay
In the case that contact acts, MCU passes through the instruction that Serial Port Line RS232 shuts down to UPS forward delay interval, such as (the UPS that shuts down after 70s
The delay switching-off time should be greater than delay switching-off time of computer equipment).This system obviates equipment to make because powering off suddenly
The parts damages such as forming apparatus hard disk.
It completes in system worked well, when needing normal shutdown, is controlled by the button operation of staff, MCU
Key press detecting circuit as shown in Figure 7 is connected, when the duration of staff's key being less than 5s, MCU controls each simultaneously
The actuating of relay, each equipment, which collects, to be saved information automatic shutdown after the corresponding actuating of relay and realizes the same of equipment 1 and equipment 2
Shi Guanji；When the duration of staff's key being greater than 5s, each actuating of relay of MCU delays time to control, each equipment is carried out
Orderly shutdown, specifically, the delay time between set device 1 and equipment 2, MCU first controls relay RL1 movement, equipment 1
It shuts down after collecting relay RL1 movement, to delay time, MCU control relay RL2 movement, equipment 2 are acquired after
It shuts down after to relay RL2 movement, realizes that equipment 1 is orderly shut down with equipment 2.
