The security of communication base stations is a constant concern for major carriers because base station equipment is expensive and indispensable, especially for storage batteries. It is the guarantee that the equipment will continue to operate after the base station is powered off, if it is destroyed or The theft will affect the normal operation of the entire communication. Therefore, the security of the battery is particularly important.
Battery GPS anti-theft device external advantages and disadvantages analysis:
1. External installation is quick and easy, no need to cut or destroy the battery, it will not affect the battery appearance and structural changes.
2. The external installation can open the mold of the disguised module to increase the concealment of the device.
3, can ensure adequate signal and power supply stability, will not damage the battery, reducing battery life.
Battery GPS anti-theft built-in pros and cons analysis:
1, the use of built-in methods need to cut the battery, and lead-acid batteries is a highly demanding airtight equipment, once cut, glued with glue, not only damage the airtightness and chemical properties of the battery, but also The inability to bond to the original battery leads to damage to the battery, which not only shortens the life of the unit battery, but also severely shortens the life of the entire battery.
2, although the built-in can do a good job in the concealment, but it will affect the GPS tracker signal reception, signal reception instability will lead to false alarm information, which can not accurately determine the occurrence of the accident.
3, after cutting, if you use an external power supply + back-up battery power supply, you need to install a GPS tracker and backup battery in a small space in the battery, if you install a lead-acid battery, that space is certainly not enough, and lead-acid battery once After a leak, it can easily cause the battery to explode, and if it is a lithium battery, the power is greater and the consequences are unimaginable.
4. If the built-in GPS device fails, it must be cut and reinstalled twice. The process is complicated, and the secondary damage to the battery will affect the use of the battery. We feel that this kind of damage to the battery, regardless of battery safety, blindly pursues the concealed behavior of the device is an irresponsible act, losing the value of the alarm device itself to protect the battery.
5, now the battery manufacturer's maintenance of the battery is generally about 3 years, if you use the built-in method will make the battery life decline, causing great pressure and loss to the battery manufacturers, believe that battery manufacturers are unwilling to bear this unwarranted Lost.
Valve part is kind of pipeline fittings, which is used to open and close, control, adjust and control the flow of medium parameters (temperature, pressure and flow). According to its function, it can be divided into the cut-off valve, check valve, regulating valve, etc.
Valve is the control unit in fluid conveying system, having function of cut-off, regulation, guide, to prevent the reverse flow, voltage regulator, the leakage of the shunt or overflow and so on. Valve parts used in fluid flow control system, have quite a wide varieties and specifications, from the most simple cut-off valve to all kinds of valves used in extremely complex automatic control system.
The valve can be used to control air, water, steam, all kinds of corrosive medium, mud, oil, liquid metal and radioactive medium. According to the material, valve part is divided into iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome molybdenum steel valves, molybdenum chrome vanadium steel valve, dual phase steel valves, plastic valves, non-standard custom-made valves, etc.
