Abstract
The utility model discloses a terminal device for monitoring anti-static status of a multistation wrist straps, which is characterized by comprising an MCU (Microprogrammed Control Unit), a plurality of signal access modules, a network unit, a power supple unit and an address dial switch, wherein the input ends of the signal access modules are connected with anti-static wrist straps, the output ends of the signal access modules are connected with the MCU, the MCU is connected with the network unit, and the address dial switch is connected with the MCU. The terminal device solves the problem of high cost caused by the reason that only one status signal of the anti-static wrist straps can be accessed to the terminal device in the prior art.
Description
Technical field
The utility model relates to a kind of end device of monitoring multistation wrist strap electrostatic prevention state, and it belongs to the static monitoring device class.
Background technology
In electronics industry, the operator causes the damage to electronic equipment in order to prevent the static electricity on human body when the assembling electronic equipment, will wear antistatic wrist strap when all requiring the operator on production line, so that the human body reliable ground, thereby the static of elimination human body.In order to make this safety practice be able to correct enforcement, generally be provided with antistatic wrist strap on the electronic assemblies production line and use condition monitoring system, whether unified this safety practice of Centralized Monitoring puts in place, the information of described antistatic wrist strap, generally the described system of device access by a terminal in the prior art, described end device generally comprises MCU, signal access module, network element and power supply unit, described power supply unit is to each module or the unit power supply of end device, a signal is processed and exported to described signal access module to MCU to the status information of antistatic wrist strap, be sent to upper system by network element at last, upper system is well-determined by the MAC Address of network element to the identification of antistatic wrist strap position.The problem that this end device of prior art exists is that an end device can only access the status information of an antistatic wrist strap, causes the cost of whole system higher, and further improved necessity is arranged for this reason.
Summary of the invention
The purpose of this utility model is to provide a kind of end device of monitoring multistation wrist strap electrostatic prevention state, to overcome the deficiencies in the prior art.
A kind of end device of monitoring multistation wrist strap electrostatic prevention state of the present utility model, comprise MCU, signal access module, network element and power supply unit, the input end of described signal access module is connected to antistatic wrist strap, the output terminal of described signal access module is connected to MCU, described MCU is connected to network element, its feature is comprising several signal access modules, and also comprises the address toggle switch, and described address toggle switch is connected to MCU.
This end device of monitoring multistation wrist strap electrostatic prevention state of the present utility model, do not pass through the position of the unique definite antistatic wrist strap of MAC Address of network element, but set the address code of the antistatic wrist strap that each signal access module connects by the address toggle switch, upper system is by the position of the address code identification antistatic wrist strap of this setting, thereby the status information of the accessible a plurality of antistatic wrist straps of end device, obviously the purpose of this utility model is achieved.
As further improvement, described signal access module is made of amplifying unit and arithmetic element, and the output of described amplifying unit is connected to arithmetic element, and the output of described arithmetic element is connected to MCU, and the input end of described amplifying unit is connected to antistatic wrist strap.Such signal access module is comparatively simple and reliable.
