A hospital bed control system includes a bed body and a foot board. The bed body includes a power source, a Hall element coupled between the power source and a conductive contact, a first infrared transceiver, and a main control device. The main control device is coupled to the first infrared transceiver. The foot board includes a control circuit, a second infrared transceiver coupled to the control circuit, a magnetic component, and a conductive pin for connecting the conductive contact. When the footboard is connected to the bed body, the magnetic element is used to change the Hall element from a first state to a second state, and the conductive pin receives a voltage from the power supply through the conductive contact and transmits the control circuit and the second infrared transceiver device, and the control circuit transmits a first data signal to the main control device through the second and first infrared transceivers.一種病床控制系統，包括一病床本體及一床尾板。病床本體包括一電源、一耦接於該電源與一導電接點之間的霍爾元件、一第一紅外線收發裝置、及一耦接第一紅外線收發裝置的主控制裝置。床尾板包括一控制電路、一耦接控制電路的第二紅外線收發裝置、一帶磁性元件、及一用以連接導電接點的導電接腳。當床尾板與病床本體連接，帶磁性元件使霍爾元件由一第一狀態改變為一第二狀態，導電接腳透過導電接點接收來自電源提供之一電壓並傳送控制電路與第二紅外線收發裝置，控制電路透過第二、第一紅外線收發裝置傳送一第一資料信號給主控制裝置。
